Tsuruko Sejren

"I'll support a body that sinks as much as the weight of the pain it endures, as long as I have supple springs! I can realize the preciousness of the light that I can see, past the times of sadness! Joy is my hope; you are the temperature!"

- Tsuruko's theme, Butterfly Sky "Shut up. I've listened to you drone on long enough. You do terrible things, and then you say it's all just destiny's will! Well I've got some very bad news for you… There's no such thing as destiny! There's only what you do, and what you don't do! Listen, I realize that life is nothing more than a series of chain reactions. If my mother had never discovered that damned particle, the wars would never have happened. Terra would still be a full world instead of five, my friends like Gary and Rosa would never have had to grow up like that, thus leading up to this day. But Giselle is Giselle; she isn't some cosmic chess piece! And as for my friends and all of that stuff they've had to go to go through, don't you dare tell me that's fate, don't tell me everything happened because it was meant to! That's a lie! It happened because of you and choices you made!"

- Tsuruko Sejren, to Mr. E, Daybreak S2, Now Depart For The Front Line! Infinity Style!.

Ethel Sejren (エセル・セジュレン, Eseru Sejuren, lit. Noble Victory), also known by her nickname of "Tsuruko" (鶴子 (ツルコ), Tsuruko lit. Crane Child), lastly known by her production number of GMC-X300A—TSUR-UK-0 (ＧＭＣ-Ｘ300Ａ-ＴＳＵＲ-ＵＫ-0; short for Giselle Mercury Custom—Xceed Three Hundred Absolutes: Tactical Soul Unison Robot-Ultimate Kaizorg-unit Zero) is a young woman who is a survivor of the dark magical ritual, she was able to subdue her emerging symbiote, by holding onto hope. This gave her the ability to use magic through the Phoenix Driver granted to her by the Phoenix Knight. With her new power, she sets out in order to make friends with everyone and unite the world via peace. She is the main character of the prequel of Fairy Tail: Dawn story, known as Daybreak Chapter: A Change of Perspective; in it, she experiences more than she had hoped for in way of the dark side of the world; she is known as the Ringed Wizard (指輪の魔法使い, Yubiwa no Mahōtsukai) for her use of her Super Soul Rings.

As it revealed in the Kaizorg Tsuruko arc, Tsuruko is, in fact, a Kaizorg (根境界接触用素体 (カイゾーグ), Kaizōgu lit. Source Interface Prime Field Device), a cybernetic organism that combines living and mechanical body parts (i.e. an organism that has both artificial and natural systems) and is specifically designed for battle; transformed into one by her mother, because as a child, she was terminally ill; the transformation was a last resort. As the only Kaizorg in existence, Tsuruko possesses the mysterious Zero Effect, which is capable of destroying all forms of magic. The mere existence of the Zero Effect is what makes her a threat to all magical organizations, and several antagonists in Daybreak want that power for themselves.

As the main protagonist, Tsuruko's point-of-view allows the audience to become acquainted to the mysterious world of the Sun Trilogy, and is mostly involved in the events of the past. Tsuruko has a very strong desire to aid all those who are in need even if it means putting her life on the line, and will not hesitate to challenge an opponent who is several times more powerful than herself. Because of her willingness to help others unconditionally, she has attracted the friendship of many characters in the series, which Giselle jokes about, stating that her life is like a dating simulation where she is bound to unlock more paths to more characters. When Tsuruko scans the Victory Ring over the Phoenix Driver, she becomes Soul Armour Knight Gaiki (神鎧纏最高戦士 (ソウル・アーマー・ナイト) ・凱輝 (ガイキ), Sōru Āmā Naito Gaiki lit. God Armour Clad Supreme Warrior Shining Victory).

Appearance
Tsuruko is a girl with dark purple hair and pupils which are colored dark blue on the top half and a mix of pink and pale yellow on the bottom half. She is stated to have "the height of your average Japanese schoolgirl" by Gary, and she has a slender, waifish build. Fiora Asakura comments that Tsuruko is a "annoying bishōjo", and Crux occasionally calls her "pure face"; a member of the Magic Council also called her a "beautiful maiden". Tsuruko's skin is also said to be so white and smooth that it appears almost like she’s made of porcelain. Her facial features are very child-like to the point that when she smiles, it is completely radiant. She has snow-white skin that is akin to a princess's; along with a beautiful figure—moderately large breasts, long, slender legs, and a shapely rear. An onlooker described her as "an impossibly beautiful girl." Due to her kind appearance, it is easier to see what Tsuruko is feeling. Unlike Giselle Mercury or Jason LaHote; this also makes her easier to talk to, though someone would have to try harder if she was upset about something or her attention was focused elsewhere.

Her hair is tied back using a butterfly-shaped hair accessory, sharing the same colour scheme as her attire. Tsuruko's casual attire consists of a cap, a red short sleeved shirt that exposes a very large portion of her midriff, a short yellow hoodie, a necklace around her neck with a puzzle piece-shaped pendant, and a low-cut green colored denim skirt with a brown pouch around her waist. She also wears a yellow bracelet on her left wrist accompanied with a ring on her pinkie finger, and knee-length brown medium heeled boots with yellow stripes on the sides.

In her Kaizorg form, Tsuruko has luminescent blue eyes that make her appear quite akin to the ideal of beauty in the current age; though her hair remains the same. Any traces of humanity are not there in terms of her body, as she possesses a cybernetic body, including sprouting shoulder-pads, high-collared neck armour, ear-like protrusions on her head which are similar to boosters, armour covering her pelvic and the sides of her abdominal region, and similarly coloured armour on her thighs; however, she has golden lining at her shoulders, upper forearms, and thighs. Her most evident cybernetic portions are above her thighs, at her shoulder-blades, and supposed lack of feet; and what isn't cybernetic reveals that her bodily joints are like that of a doll's.

Personality and Traits
Thanks to being separated from her childhood friend at a young age, Tsuruko's personality had changed drastically; becoming depressed and sad from the split. She is shown to be a shut-in, highly nervous and constantly stuttering in her speech. She has trouble socializing with others; more often than not imitating clichés seen in fiction in a bad attempt to endear herself to others. Tsuruko is the definition of the "shrinking violet" archetype. She is shy, clumsy, and tends to get worked up over the smallest things; more often than not always late and constantly apologizing. She can be socially awkward at times, but this has actually served as an endearing trait, which earns her many of her friendships. In spite of this, she is shown to be quite passionate and determined when motivated, and is loyal to her friends and allies.

Tsuruko is extremely humble about her power. Despite the great power she possesses, she always defers to her friends or allies, and rarely wants to take the spotlight, even when her friends encourage her to do so; a result of her low self-esteem or a guilt complex. She honestly and truly doesn't think of herself as any better than anyone else, despite the great deeds she's done, or the inspiration she's become. In fact, such praise usually just embarrasses her; and even so, she's not going to ever let unpopularity stop her from helping others; she enjoys helping people in need, especially children, whom she has a fondness for, and in the case of her friends, she can been seen as a figure akin to a mother.

Additionally, Tsuruko normally acts like a klutz; she's definitely not known for her grace. She bumbles and fumbles at seemingly anything she does, tripping over things a fair bit; only Tsuruko could accidentally kick a pen into a highway right in front of a passing car while trying to pick it up. This dizziness extends to her romantic life; she is completely oblivious to Crux's increasingly obvious crush on her; this also extends to nearly everyone else's feelins for her. However, despite this, it is not well-known that Tsuruko actually actively encourages her reputation as an incompetent fool on occasion in order to keep people from bothering with her, and thus not worry about her.

Tsuruko doesn't like for a lot of attention to be drawn towards her, as shown when she told Giselle she didn't want people to think she was special. This is odd seeing as how becoming a member of La Pucelle would effectively put her in the spotlight. But because of her nature, it is increasingly obvious that Tsuruko is doing this to become the best she can be in order to best help others; saying that "you don't need a reason to help somebody". She can be unabashedly enthusiastic about trying to socialize; prone to becoming very animated and talkative, gesturing broadly and providing sound effects; people have called her "adorably dorky".

Tsuruko wishes to make friends with everyone. She is willing to go the extra mile and do bizarre things to get to know someone she wants to befriend better. She puts friendship above anything else and values every friend that she has, to the point of crying hard whenever she hears a sad story of someone she considers a friend. She also has a special handshake she does with her friends and is commonly used when Tsuruko makes a new friend. The reason she does so is because she wants to see that person she befriends smile, which is the best feeling one could have—however, her low self-esteem encourages this behaviour, but despite this, when she really does pull through, people see the "real" Tsuruko for the first time. Tsuruko is seen to go through any means necessary to save a friend: not only did she risk her life after Kaguya was struck by a demon's bow despite Kaguya's hatred of her, but she also refused to leave Aeris' side during the battle with Psyga the first time, even when it appeared that her new friend was dead, as she carried Aeris' body throughout the first part of her battle with the demon.

Tsuruko is shown to be still naive to more serious matters in the world and maybe even a little bit childish. Then there's the soft and unfettered side to her personality that shows compassion to every person and being, and how everyone is being treated. With her job out of the way, she enjoys relaxing with friends and reminiscing, nostalgically. Tsuruko is known to be extremely nervous when faced with something big, for example popular figures or superiors and she is well aware of this; more often than not keeping her head down in important meetings so that she would not have to speak up and thus make a total embarrassment of herself. She's also very good at reading people's emotions and true feelings; Tsuruko's ultimate strength may lie in her unflappable kindness. Tsuruko is helpful and caring to her friends, like a surrogate mother; she tries to "mother" Crux, and make sure he eats properly, with debatable levels of success, but ends up being more successful in the case of Gary and Kaguya. She is more than happy to listen to her friends' woes — lending helpful and worldly advice whenever possible.

As it turns out, Tsuruko's physiology is not ideal for Super Soul Ring use, and she was never the ideal choice for the wielder of the rings. Because of this, she had trouble maintaining her Transformation Rings when Rosa's power was evolving. However, she later proves that she has a knack for being the 'wild card', being incredibly difficult to predict in such a manner - this quality leads not only to her resonating strongly with the Joker Ring and match Rosa's heightened power, but also displaying the ability to exceed expectations and being able to transform into Infinity Style by sheer willpower.

Strawberry ice-cream is one of the few things she is fond of, but it is also one of the things that she hates. She despises cold food, but always seems to buy it from the convenience store. It is revealed in flashbacks that Tsuruko collects comics and was a fan of the Earth Land equivalent of Batman when she was young. She becomes a fan of Gaikou Ryuusei's works when she is much older. Tsuruko has a mindset where she tries to imagine the consequences her actions would have on other people, even if they appear to be enemies. She is gentle and sympathetic, and despite her skill in fighting she will never brutally harm a person unnecessarily, although she understands that sometimes she must do so; overall, Tsuruko is a pacifist, yet despite her dislike of war and conflict, she is more than willing to fight if it means protecting her friends and loved ones. In battle, she will aim to disable the enemy instead of killing them outright, believing that she needs to prevent as many tragedies as possible by trying to fight without killing anyone.

In battle, Tsuruko reveals a much more bolder-side to herself. What is notable is that Tsuruko's eccentrics like posing; pre-battle speeches and calling her attacks that makes Tsuruko resemble more traditional "heroes" in shōnen anime. In battle, surprisingly enough, Tsuruko is extremely hot-blooded and hammy, but she is incredibly savvy. At crucial points in battles, she will verbally predict what will happen to her enemies in a Fist of the North Star-like fashion, and quote, often verbatim, what they will say. Her enemy will then unwittingly repeat said prediction, shocked by Tsuruko's "mind reading". Additionally, Tsuruko is known to be somebody who can understand and affect her opponent's psychology through fighting; leading her to make many allies out of enemies. Before she begins a battle, Tsuruko proclaims "Now, it's showtime!" (さあ、ショータイムだ!, Saa, shōtaimu da!); whenever she executes one of her finishers, she declares, "The finale!" (フィナーレだ!, Fināre da!). Before a climatic battle begins, Tsuruko answers a major villain's demand for her identity by saying that she is "Just passing through, remember that!" (通り過がりだ、覚えておけ！ Tōrisugari da, oboeteoke!).

History
"I will never lose hope!"

- Tsuruko's declaration.

Tsuruko's father, Alphonse Sejren, was a research subject of the Zodiac Knights. They were trying to create a symbiote inside his body. When her mother, Giselle Mercury learned of the Zodiac Knights' plan to create an Demon Impact, she attacked them and descended upon this land, where she met Alphonse. After meeting him, she realized that she couldn't defeat the Zodiac Knights by herself. She began to search for a way for somebody to harness the power to destroy demons to put an end to the Zodiac Knights, the Dust to Dust Ancient Spell. Soon after, Alphonse and Giselle fell in love and eloped; their love soon gave birth to Tsuruko. They lived happily, until one day.

Alphonse and Giselle were pursued by Kirika Hotsuin. They traveled from place to place, and when Tsuruko was born, with her as well, but they were finally caught by Kirika. When Tsuruko was born, she was gravely ill; the reason for that, is during her birth, Alphonse's symbiote, Star Phoenix, transferred from him into Tsuruko. Tsuruko had an incurable disease that science couldn't fix; Giselle tried so hard to save her daughter; but in the end, she could only resort to an option that crushed her; she had to convert Tsuruko into a Kaizorg in order to stop the disease from progressing. As Tsuruko's flesh and bone converted to Orichalcum, Giselle regretted her next options ever since: she converted the Dust to Dust Ancient Spell into data, storing it on a disk called the Laplace Program, and installed it into Tsuruko's body, so that she would be able to activate Dust to Dust whenever she felt a strong emotion. But because of that, she was hunted by the Magic Council as well as the Zodiac Knights.

Alphonse was turned into a monster as Kirika tried to fight Giselle; the lack of symbiote inside of him caused the magical power inside of him to go out of control, and he turned into a demon. When it tried to devour Tsuruko, Giselle had no choice but to use the True Phoenix Driver to become the Phoenix Knight; and Alphonse tried to devour her, Giselle fought him until he regained control of himself, no matter how momentarily it was; but he asked Giselle to kill him. After that, Kirika attacked, then Tsuruko fell down the cliff along with the Phoenix Driver that Giselle created for Tsuruko. Giselle fought off Kirika, and descended the cliff, but all that was left were the symbiote corpses, half-eaten by monsters; believing that there was no way that Tsuruko would have survived, she despaired and left the vicinity.

Thankfully, Elincia found the young Tsuruko and Alphonse in the forest of the mountain village of Four; who, on the verge of death, told her how they ended up there and asked Elincia to raise his daughter as her own; to which Elincia accepted; as Elincia also made Tsuruko believe that her parents died in an accident, and not by the Zodiac Knights. During her childhood, Tsuruko was neighbors with Gary Straights. Tsuruko grew up isolated from the rest of the village children, feeling herself to be better than them, though she longed for their friendship. She developed a crush on Gary, but hated his friends. Although the two consider each other (and are considered by others) to be childhood friends, by Gary's own account they were not close growing up, despite her having been his neighbor.

When Tsuruko was nine, Gary's mother died, and Gary insisted he could meet her again by crossing the mountains. Tsuruko followed, and when Gary was injured the townsfolk believed the expedition up the mountain to be Tsuruko's idea, and Gary's father forbade Tsuruko from approaching him. Tsuruko blamed herself thinking it was her weakness she failed to save him, and developed an anger problem, often getting into fights, but in spite of this she was still a quiet kid who rarely had much to do with the other kids in the village.

The promise she made to her father to keep hope alive in her heart saved Tsuruko's life years later when she was among the humans sacrificed during a solar eclipse to create symbiotes. Six months prior to the series, pro-soccer player Tsuruko Sejren was subjected among many others in a ritualistic sacrifice that created the demons on the day of a solar eclipse. While many died giving birth to their symbiotes, Tsuruko managed to keep her symbiotes, Star Phoenix from emerging by facing despair head on and as a result she obtained dormant magical powers.

Coming to after the eclipse ended, Tsuruko was attacked by one of the newly-born symbiotes until she was saved by the mysterious Phoenix Knight who presented her with the Phoenix Driver and the Laser Ring so that she can access her magic and track down the symbiotes and fight them. Motivated to give hope and save people from despair so no symbiote could ever be born again, Tsuruko decided to fight for the people; protecting them from all harm.

Equipment
"Ah, ya see, I created Dragredder from scratch. A hero always has a cool weapon—and what better than a mix and match weapon? Swords are everywhere; so are guns. So why not have a fusion of both? I tweaked it excessively so that I can use it better too; and while it's hard to get a hang of, once I managed to master it, there's no weapon better."

- Tsuruko Sejren to Hikari Zanna, on Dragredder; Innocent Origins

Dragredder (ドラグレッダー, Doragureddā): The strongest member of the Divine Tools; Kyūkyokusenjin (究極戦刃, Ultimate Battle Blade), given the nickname of Dragredder; is a powerful gunblade (ガンブレード, Ganburēdo); a type of weapon only recently developed in the past decade; Tsuruko herself built Dragredder from scratch, tweaking it excessively so that it was so highly customized that only Tsuruko herself can wield it effectively. Like the other weapons in the series, Dragredder has a designation; that of the High Velocity Sword Gun (高速剣銃, Kōsokukenjū). Essentially, the gunblade is exactly what it says on the tin—it has the ability to transform between gun-mode and blade-mode. The weapon is an ingenious integration of sword and firearm into a single instrument for killing purposes. The weapon is equally capable of dispatching enemies at close-quarters and at range. Dragredder is capable of both melee and long-range properties. Dragredder itself is uniquely shaped; loosely based upon a falchion in template, Dragredder possesses an ornately etched base; it possesses a thin, somewhat curved, blade, with a thick line, colored a darker hue, running up the center. Placed in the hilt lies a blue gem, surrounded by the brown-colored handle that gains a mechanical appearance overall, with outward sticking cylindrical protrusions, the tips of which are colored a brick red. In order to transform between the modes, the blade folds inward from the top. So, when it's release, it unfolds from the top outward, as opposed to from the bottom outward; the method is similar to that of a swiss army knife—in order to transform it safely, Tsuruko tilts it to the side; otherwise, she would cut herself if it folded in the bottom, so it folds from the top, making deployment a little safer. However, despite the dangers, the transformation from sword to gun mode is extremely fluid and smooth; not to mention quick. When Dragredder is folded into gun mode, the blade is retracted and double folded; revealing the hilt of the weapon to be a powerful two-barrel blaster as the grip is adjusted slightly downward, providing a perfectly serviceable submachinegun. Dragredder is made of a special metal that is almost unbreakable, making it stand out clearly from any other gunblade. The whole construction and the design of the blade is unique, and Dragredder does not need a different setting, since that would bring it off balance. Tsuruko uses both the weapon's sword and gun forms, quickly switching between the two while attacking to combine close and long-range tactics, such as firing a barrage of gunfire then diving in for a sword slash. When held in front of her, Dragredder is broad enough to act as a shield from arrows and bolts, even diverting lightning into the ground by using it as a lightning rod. Tsuruko also uses it to cushion her impact by laying the sword level with her body and letting it absorb the impact first. It is a blade that exists in the astral and physical realms simultaneously; allowing Tsuruko to harm all sorts of beings that could not be struck otherwise, such as Primordial Demons and Dragons; it is armed with silver bullets, which is adversive to a demon. Humourously, Dragredder is given the nickname BirdySwordGun (バーディソードガン, Bādisōdogan) by Gary Straights. By inserting a Super Soul Ring into the upgraded Dragredder's Energy Drive Bay (エナジー・ドライブ・ベイ, Enajī Doraibu Beī) and locking it in place, the user can perform a Ring Charge (リング・チャージ, Ringu Chāji) finishing technique, which is announced by Dragredder counting "1, 10, 100" (一、十、百, Ichi, Jū, Hyaku). Dragredder can count higher to "1000" (千, Sen) and "10000" (万, Man) when Tsuruko pulls the lever on the Phoenix Driver. When Tsuruko obtains the Shin Gaiki Soul Armour, the Ring Charge can reach up to "100,000,000" (億, Oku), "1,000,000,000,000" (兆, Chō), and "Muryodaisu" (無量大数, Immeasurable Large Number, which is the number Infinity in modern day mathematics); reaching the limits of its power.
 * Kinetic Tether: The kinetic tether is an illegal attachment to any type of magical sword. Tsuruko uses it to move a specific object from a distance, move specific bridges and load various spring-like pads; additionally, it allows her to move around. It works by splitting the sword into halves and using a blue kinetic energy tether to connect the two halves. When it is being used, the tether extends sending the tip of Dragredder flying through the air. If the tip latches onto certain objects, Tsuruko is projected towards that object, rather than the tether returning to its original position. This attachment is used commonly to grapple onto far away objects so that Tsuruko can reach previously inaccessible areas. In addition it allows Tsuruko to grab far away objects and attack enemies. In most cases, attacking a foe with the Kinetic Tether will only stun them, much to Tsuruko's dismay. The Kinetic Tether allows her to grapple and pull herself towards one target, then grapple another target without the need to drop down, making it perfect for moving around hazardous areas.

Phoenix Driver (フェニックス・ドライバー, Fenikkusu Doraibā): The Phoenix Driver is a mysterious Driver Belt that was given to Tsuruko by the equally mystifying Phoenix Knight- in reality, the Phoenix Driver was the first Driver Belt to be developed; the rest, including Phenex's belt, were reverse-engineered from it. The Phoenix Driver is a tricked-out crimson belt which has a phoenix-shaped belt buckle—the phoenix symbol has a flashing golden symbol in the middle, which Tsuruko uses to scan her rings. On the side, there is a lever which Tsuruko can pull in order to bolster the power of her very next attack significantly. It should be noted that the Phoenix Driver is the only Driver Belt that doesn't require magical energy to use, as it was created when magic did not exist. By wearing a Transformation Ring on her left hand and swinging it across the belt buckle after activating the Driver; the Phoenix Driver will authorize the usage of the Super Soul Ring, thus giving it even more power; enabling her to utilize their full potential. If a Super Soul Ring is scanned by a wearer without magical power (or isn't related to Dzerve or isn't Tsuruko), the Phoenix Driver will announce "Error" (エラー, Erā), meaning it will not be granted. In order to utilize her strongest attacks, Tsuruko pushes the lever on the side of the belt down—this causes energy to flow into her body which the Phoenix Driver has gathered from the environment. Once the energy has been condensed, Tsuruko must quickly expel it in the form of her finishing attack known as a Limit Break (リミト・ブリク, Rimito Buriku); otherwise, it will overload her body. While executing a Double Limit Break is possible, it is risky as it would completely drain a Super Soul Ring's power for a while, rendering one of them useless until they are completely recharged. When not transformed, the Phoenix Driver appears as an ordinary belt with a hand-shaped buckle, though it retains the ability to utilize any Super Soul Ring. As a side note, the Phoenix Driver (and Gaiki by extension) seems to have a degree of sentience, as shown in Daybreak: Infinity Future, even when "Dzerve" took the belt and utilized it (as the belt recognized its creator as one of its two "qualified users"), the moment that Tsuruko grabbed it while it was on Dzerve's waist and shouted the transformation call, it broke off from Dzerve's body by giving her a powerful electric shock, cancelling her transformation as Gaiki, and allowed Tsuruko to transform once more.

Arcle (アークル, Ākuru): The Arcle is a personal transformation device that Tsuruko finds buried near her father's grave—it is an ancient artifact developed by Lunarians eons ago in order to control the wearer's inner darkness. While it remained concealed in obsidian, Tsuruko had managed to awaken it once more by her resolve—the Arcle is an arm-mounted device awakened from all of Star Phoenix's elemental magical energy that was spilt out from Tsuruko's body when she was attacked by Kirika Hotsuin. Realizing that Kirika's ability had her at a disadvantage, Tsuruko was almost killed by her; leaving her powerless for several days. After she found the Arcle at her father's grave at four, she was saved by the Phoenix Knight, who took her to a strange altar. There, Tsuruko was told of a ritual to become stronger by drawing the full potential of her symbiote, Star Phoenix, and she accepted to do it after being warned of the risks. Enduring the pain, Tsuruko awakened the Arcle, which became a manifestation of her eternano. The Arcle suppresses Tsuruko's quickening into despair by turning the hopes of those that believe in her into power—this causes her Styles to become upgraded; becoming golden hued versions of her standard ones, known as Rising Styles; which are shown to have additional gold trimmings and extensions and the mark of power (chikara written in ancient Lunarian writings) on the back of Tsuruko's hands.

Buster Cannon (バスター・キャノン, Basutā Kyanon): The Buster Cannon is a personalized arm cannon that Tsuruko manifests by pumping energy into her right hand and then solidifying it while keeping the image of an arm cannon in mind, essentially forming the Buster Cannon from pure willpower and energy. The Buster Cannon is an azure arm-cannon that reaches up to Tsuruko's elbow; with several silver flame-esque decals, and the barrel of the cannon possesses a quartet of wings pointing in all four directions; otherwise, it has a single cannon protruding outwards. The Buster Cannon is equipped with an energy condenser, and is capable of matching the output of Etherion, if not overpowering it easily. Tsuruko can transform any of her arms into a powerful arm cannon to attack, and has an energy amplifier that allows it to be charged up and release a more powerful shot. The Buster-Cannon releases highly condensed blasts of white light that can burn the surrounding area it comes into contact with, and even leave those who stare at it temporarily blind; it has a high rate of fire, enabling Tsuruko to overwhelm her foes with a near continuous stream of blasts. In its weakest form it is capable of puncturing steel and destroying boulders. The charged version can blow a five foot diameter hole in a wall of solid diamond. Moreover, it is stated that a single shot from the Buster Cannon possesses the energy of 4 normal Abyss Break blasts. Normally, it functions like an ordinary arm cannon but utilizes a special Eternano-cap magazine mechanism to produce Etherion yields at the expense of an entire Eternano-cap battery. Each magazine is loaded with 5-battery clip, allowing a total of five shots before a new magazine is needed. What is interesting to note is that her buster system is potentially extremely powerful in the fact that its charging capabilities are theoretically infinite.

Telescoping System: The Telescoping System is a special function of Tsuruko's Kaizorg body—due to Giselle building so much weaponry into her small figure, she had to imbue Teleportation Magic into her Orichalcum bones and store the weaponry within a transdimensional space connected to her magic origin; only to reappear at will. When the weaponry shows itself, her limbs extend, armour appears, weaponry will sprout from nowhere, hatches will open up in various parts of her body to reveal even more weapons, and she will become ten metric tonnes heavier than before.

Super Soul Rings (超魂リング, Chōkon Ringu): The Super Soul Rings are mysterious items with the power to convert the willpower that flows inside the human body into Tenchōkon (天超魂, Heaven Super Soul). The process behind this conversion is obscure in details, but it has been said that an individual's resolve plays a major role in determining its success and efficiency. The Super Soul Rings give access to the wielder's form changes and spells, depending on which style the ring is. The Super Soul Rings contain Tenchōkon, which has many powers, even possessing the ability to power machinery. It transforms Tsuruko and gives her power, converts demons back to their normal selves, teleports whole villages, and may have other unknown uses. Due to being half-Lunarian, Tsuruko is the only character than Mr. E who can naturally utilize that power; by harnessing the strong energy from a Super Soul Ring, Tsuruko is able to use its power, transforming into a different form that grants a special ability, such as new attacks or environmental advantages. The type of transformation and ability she obtains depends on the type of Super Soul Ring and its energy; able to tap into the ring's innate Tenchōkon reserves, allowing her to use the Super Soul Ring to grant herself new abilities and/powers that she would otherwise not have, such as shooting herself forward as a laser, create explosions of fire or even manipulate certain objects within the area. The powers of the Super Soul Rings can only be maintained for a short period of time, however, meaning that their effects will only last for a short while, and constantly requires more Tenchōkon from Tsuruko to be maintained. Amadam is said to be the originator of the Super Soul Rings that Tsuruko uses; however, Tsuruko, through help from Giselle Mercury, has refined the rings so that they have a higher output than E's rings; and as a side-effect, Amadam has no control over the rings.
 * Victory Ring (ヴィクトリー・リング, Vikutorī Ringu): The Victory Ring is a special Super Soul Ring which awakened from Tsuruko's resolve to save both humans and symbiotes—the Arcle allowed the Super Soul Ring to be birthed into this plane of existence. It, like the other Transformation Rings, affect space-time; and was created by the Lunarians eons ago; whom in turn gave the Transformation Rings to humans so that they may protect them from demons that would arrive later. The Transformation Rings appear instantaneously from another dimension to the selected personnel so that they may transform into the respective Soul Armour Knight to fight any enemies in the vicinity. It first appears when Tsuruko is in mortal danger from being attacked by Jin Hissatsu; causing her to resolve to save both humans and symbiotes. Being made to protect Tsuruko by Alphonse and act as her bodyguard, the Victory Ring shows up whenever she is in danger or whenever she calls for it. The Victory Ring's powers come directly from the Zero Effect and are accessed through the Crystal Server on Gaiki. In order to initiate the transformation into Gaiki, after slipping the Victory Ring on her finger, the Arcle is placed on the left pad of the Phoenix Driver horizontally, then turned 90 degrees so that the phoenix symbol on the belt's gem is upright. After placing the Arcle upright, Tsuruko pushes the horn lever on the Arcle; causing her body to become engulfed in light, before transforming. The code of the Victory Ring is SSR-07.
 * Maximum Ring (マキシマム・リング, Makishimamu Ringu): The Maximum Ring is a golden Super Soul Ring which possesses a multicoloured gem encrusted within the base; the gem possesses numerous symbols within the textures; representing it's true use. The Maximum Ring was designed by Giselle Mercury and given to Tsuruko Sejren; when Tsuruko scans the Maximum Ring over the Phoenix Driver with her teammates in close proximity, it allows the Phoenix Driver to link to their own willpowers—and once this is done, they focus their minds upon Tsuruko, combining all of their willpower as one. This forms a Unison Raid (合体魔法, ユニゾンレイド, Yunizon Reido) of sorts; which is an extremely powerful spell that allows two Mages to unite Magics similar in nature together, thereby creating an even stronger attack; though tuned to Ardor instead. Many priests have wasted their entire lives trying to achieve Unison Raid without success, thus implying that it is an extremely difficult spell to master. However, in the case of the Maximum Ring, the resonance caused by being scanned over the Phoenix Driver causes something greater than a regular Unison Raid, allowing all seven members of Team Daybreak (and Kirika and Sion) to unite their willpower, via focusing it through Tsuruko's Buster Cannon, essentially focusing all of their power into a single vessel; this results in a blast of overwhelming power without any equal, known as the "X Shining Hopes Victory Maximum Finish" ((六／七／八／九／十／十一）光幾ビクトリーマキシマムフィニッシュ (Roku / Nana / Hachi / Kyū / Jū ／ Jū Ichi) Kōki Bikutorī Makishimamu Finisshu).
 * Nine Shining Hopes Victory Maximum Finish (九光幾ビクトリーマキシマムフィニッシュ, Kyūkōki Bikutorī Makishimamu Finisshu): The strongest version of the Shining Hopes Victory Maximum Finish, when performing it; Tsuruko scans the Maximum Ring over the Phoenix Driver, causing a powerful resonance which reverberates throughout the area, connecting Tsuruko's Ardor with the Ardor of all six other members of Team Daybreak (as well as Kirika and Sion), and focusing it through a single conduit—Tsuruko's Buster Cannon. Once this is done, all of their willpower is gathered; uniting their powers into the arm-cannon as it is released in the form of an overwhelming blast of unparalleled power that expands vertically as it moves away from Tsuruko. As the blast moves away from her, opponents that come in contact with the vortex are knocked slightly to the side, and are thus forced to travel with it. Opponents that are in the center of the vortex are more easily trapped by it. Tsuruko recoils slightly when she does the attack, but she is unaffected by gravity until the move ends, so it is mostly insignificant. The move is capable of hitting about 7.5 times a second, although this is unlikely due to the speed the blasts spin at and the knockback delivered; it razes the earth and destroys the skies; all for the purpose of eliminating the enemy in front of Tsuruko. It is capable of inflicting damage on a wide range of multiple enemies and pushing them back quite some distance without allowing recovery, possibly even dragging opponents off the side. The Nine Shining Hopes Victory Maximum Finish is without a doubt, Tsuruko's most powerful attack; possessing a power without equal—after obtaining the method in which to utilize it, it has been the finishing attack for all of the major antagonists in Daybreak.
 * Infinity Ring (インフィニティ・リング, Infiniti Ringu): The most powerful Transformation Ring to ever exist; Infinity Style is also known as the "evolution of infinite possibilities," and is the true form of Gaiki, awakened by Tsuruko's resolve to defeat Amadam near the climax of Daybreak S2. The Infinity Ring is a golden Super Soul Ring with a multicoloured gem in the middle; representing all of Tsuruko's powers. It was an evolution unlike anything ever anticipated by anyone, born when Tsuruko molts after Jonas had given her a stern lecture about learning to be selfish for once. It is at this point that Tsuruko declares that she will defeat Amadam and return the world to its former state, and, in a blast of light-based power, the Infinity Ring is created with her resolve. When Tsuruko slips the ring on her finger, the Star Phoenix appears before her, revealing that Tsuruko's determination is what made him change and offers his help once more. When Tsuruko scans it over the Phoenix Driver, it allows her to become Infinity Style, equipped with an alternating arsenal of Blue Rose, Balmung, Vort Grenade, and Aegis alongside Dragredder. The Infinity Ring also allows Tsuruko to move at blinding speeds when scanned on the Phoenix Driver a second time after the transformation, as well as imbue her Dragredder with the Zero Effect when scanned on Dragredder's Core Bay. Though she later gave it back to Jonas after defeating Amadam, seeing no need for such a powerful ring anymore, Tsuruko would acquire another Infinity Ring, which originally belonged to her Bujin counterpart. Its code is SSR- (SSR-Infinity); showing that the Infinity Ring is the most powerful of them all. However, the Infinity Ring is actually part of a pair, with the other member of said pair being a special Super Soul Ring known as the Finish Strike Ring, which enables Tsuruko to take upon her ultimate form, if only for a moment.
 * Finish Strike Ring (フィニッシュ・ストライク・リング, Finisshu Sutoraiku Ringu): The Finish Strike Ring is a Super Soul Ring that is only compatible with Tsuruko Sejren's Infinity Style; being only capable of being scanned over the Phoenix Driver when Gaiki is in Infinity Style. The Finish Strike Ring is a golden Super Soul Ring that has twin phoenixes arranged in a yin-yang pattern, along with a large ruby in the middle. When Tsuruko scans the Finish Strike Ring over the Phoenix Driver when in Infinity Style, it lets out a high-pitched squawk as the scanning releases a pulse of aura, that is indicated to be pure Source energy which surrounds Tsuruko's body, cloaking her in intense light. When cloaked in light, the Phoenix Driver becomes gold and its trim becomes red, which is similar to the other Driver Belts; as Star Phoenix's Phoenix Armaments manifest from the armour of Infinity Style, becoming the Infinity Skull (インフィニティ・スカル, Infiniti Sukaru), Infinity Tail (インフィニティ・テイル, Infiniti Teiru), Infinity Wings (インフィニティ・ウィング, Infiniti Uingu), and Infinity Hell Claws (インフィニティ・ヘル・クロー, Infiniti Heru Kurō); the attachments are far more powerful and silver. This arrangement causes Gaiki Infinity Style to take upon the Pseudo-Style known as Infinity Phoenix Style (インフィニティ・フェニックス・スタイル, Infiniti Fenikkusu Sutairu), which exists only for a moment, as Tsuruko shoots towards the enemy at amazing speeds, gathering and condensing the Zero Effect upon her feet as she manifests the Infinity Skull upon her right foot to strengthen the power of her kick, as she summons a massive seal of energy, then hits the target with elemental constructs of Star Phoenix, then slams a powerful flying kick into the weakened target known as Infinity End (インフィニティ・ーエンド, Infinitī Endo). Even if made into a non-lethal kick, this attack still has enough force to send an opponent all the way to the sun at high speeds.

Prototype-00 Revised: Longinus Blade (試作零号機・改・鏖殺公 (ロンギヌス・ブレード), Shikasu Zerogōki Kai Ronginusu Burēdo lit. Throne of Annihilation): The Prototype-00 Revised: Longinus Blade is a Magitek Weapon created specifically for use in combat; forged from a fusion of magical energy and cold, hard Orichalcum. The Longinus Blade utilizes the primeval power of eternano to provide the people with the basics of fire, water, light, and most importantly, protection against enemies. These objects achieve their functions by converting eternano from any source, even that of the user's magical aura, into energy by way of a formula. They are marked by crests that indicate their attributes. If a piece of Magitek breaks, it loses its ability to absorb eternano, causing it to malfunction. Magitek is composed of two parts: the body and core. The body is the most distinctive part of a Magitek, responsible for controlling the magic that is generated by the core. The core is a small sphere inside the body, which produce the magic through formulas which absorb eternano. Unlike the body, which is easily produced through artificial means, the core is difficult to make without proper materials, leading many people to steal them. While its origins are a mystery, its first appearance was when Tsuruko remarked that her power always evolving and is faster than light during the battle with Alexis, after obtaining Amakusa, and called upon the Longinus Blade. Normally, the Longinus Blade takes on the appearance of a gilded throne which doubles as the scabbard of Dragredder; the throne itself seems to be a sort of support machine, based on how she uses it. It can be changed into a transport vessel by laying it horizontally, or to unlock the final form of her weapon, by cutting the throne into exact halves. The throne itself seems to be a sort of support machine, based on how Tsuruko uses it. It can be changed into a transport vessel by laying it horizontally, or to unlock the final form of her weapon, Halvanhelev, by cutting the throne into exact halves. Tsuruko can set the Longinus Blade down at any moment; after which, it produces a pulling field which will pull her opponent towards it; or alternatively, she can switch the throne to a repelling field which pushes her opponent away; if the opponent is close, it will deal small damage. Once the opponent is within the range of the Longinus Blade; once drawn in by the polarity, it will unveil its true power; which is to open up into the form of various contraptions which were created for the sole purpose of obliterating her opponent while keeping them on-edge thanks to its numerous functions. The thing to note about the Longinus Blade is that it can perform almost infinite functions; showing various elemental attacks, gravity manipulation, as well as teleportation in its skill-set. For Tsuruko, the Longinus Blade can also combine with some of her Arms Weapons to become an alternate mode for more powerful attacks; like Tsuruko's Dragredder to become the Dragredder Naginata Mode (ドラグレッダー・ナギナタ・モード, Doragureddā Naginata Mōdo); which is used more like a double weapon to allow Tsuruko to attack from all sides, or the Buster Cannon to become the Buster Cannon Laser Mode (バスター・キャノン・レーザー・モード, Basutā Kyanon Rēzā Mōdo); which attaches the Longinus Blade's throne to her Buster Cannon in order to serve as a massive wave motion gun; both are capable of unleashing far more powerful attacks.
 * Armament No.04β – "Hyper-Torrid Flame Bell Vogue Ver. 2.73" (武装No04β「超炎熱フレイムベルボーグVer2.73」, Busō No04β "Chō En'netsu Fureimu Beru Bōgu Ver2.73"): Armament No.04β – "Hyper-Torrid Flame Bell Vogue Ver. 2.73" is the first special ability that the Longinus Blade displays; when activating Hyper-Torrid Flame Bell Vogue, the Longinus Blade consumes a substantial amount of eternano, absorbing it before condensing it at the tip of the throne. Once this has done, the eternano gathered is released in the form of a powerful sphere of flame which is launched upwards; slowly descending. This attack releases highly condensed blasts of flame that can burn the surrounding area it comes into contact with, and even leave those who stare at it temporarily blind; it has a high rate of fire, enabling Tsuruko to overwhelm her foes with a near continuous stream of blasts. It will "fizzle" out after a certain range, but if charged to the maximum, it can hit twice, and will continue to fly without fading. The flame released is multi-hitting, the maximum usually being 5 hits, and it has a property that lets it break through any projectile, which usually catches foes by surprise, as well as blow reinforced, solid titanium walls without effort, making it one of the most powerful functions of Sandalphon.
 * Armament No.05 – "Electric Shock Banishing Ray Ver. 3.10" (武装No05「電撃バニシングレイVer3.10」, Busō No05 "Dengeki Banishingu Rei Ver.3.10"): Armament No.05 – "Electric Shock Banishing Ray Ver. 3.10" is the second special ability that the Longinus Blade displays; when activating Electric Shock Banishing Ray, the Longinus Blade consumes a substantial amount of eternano, absorbing it before condensing it at the tip of the throne. Once this has done, the eternano gathered is released in the form of an extremely large and destructive sparking blast, which produces an immense amount of light and is capable of travelling for great distances, wreaking havoc wherever it passes; a side-effect of being hit by this attack is, if the target survives, the lightning paralyzes them, preventing them from escaping the next attack. Banishing Ray is multi-hitting, the maximum usually being 5 hits, and it has a property that lets it break through any projectile, which usually catches foes by surprise, as well as blow reinforced, solid titanium walls without effort, making it one of its most powerful techniques. It seems that the longer the intervals in not casting the attack, the stronger that Banishing Ray becomes—for instance, while utilizing it in quick succession is good to rush the opponent with; waiting around five minutes before casting it causes Banishing Ray to become a spell worthy of a "finishing move". When used at its full potential, it carries a dangerous ability. While it continues to destroy everything around the attack, the designated opponent is surrounded by the energy of Banishing Ray when hit.
 * Armament No.02 – "Assaulting Broken Bunker Ver. 2.21" (武装No02「突撃ブロークンバンカーVer2.21」, Busō No02 "Totsugeki Burōkun Bankā Ver2.21"): Armament No.02 – "Assaulting Broken Bunker Ver. 2.21" is the third special ability that the Longinus Blade displays; when activating Assaulting Broken Bunker, the Longinus Blade consumes a substantial amount of eternano, absorbing it before condensing it at the tip of the throne. Once this has done, the eternano gathered is released in the form of a vicious volley of missiles which launch towards the opponent, locking on to their heat signature on the way. Each missile contains the properties of targeting and propulsion, always condensing the eternano particles that are inside of it, before spreading them out to the tip, coating the outer surface of the missile, enhancing its penetrative qualities; the Longinus Blade unleashes a vicious onslaught of missiles at Tsuruko's opponent; upon contact with the foe, each of the missiles release all of the eternano that compose it—the foe's own magical aura serves to contain and amplify the destructive power of each missile; before warping the surface and exploding, dealing tremendous damage.
 * TsurukoBFS.pngArmament No.99 – Halvanhelev (武装No99神滅の剣（ハルヴァンヘレヴ）, Busō No99 Haruvuanherevu lit. The Sword that Destroys God): Halvanhelev, the Sword that Destroys God, also known as Blazing Sword Mode (ブレージング・ソード・モード, Burējingu Sōdo Mōdo) is the ultimate form of the Longinus Blade; when accessing its power, Tsuruko cuts the throne of the Longinus Blade into exact halves, before they attach to Dragredder, forming an enormous blade which is twenty meters long in length; being over ten times Tsuruko's own height. This gives Dragredder elemental properties, in addition to unrestrained cutting power. When Tsuruko's blade is infused with their raw magical power, it replaces the hard, metal blade of the sword with a blade of light, similar to a laser. When Halvanhelev is in effect, it turns Tsuruko's attack into a power on the physical and magical side. This makes it incredibly useful for fighting demons, who do not have physical bodies and therefore can only be hurt with magic. It can also be used against foes whose magic bodies are LonginusBladeHalvahelev.pngd off or missing, and thus are immune to most magic. The Halvanhelev is powerful enough to destroy lesser demons and weak Espers in a single blow if Tsuruko can manage to hit them. Even middle-ranking demons can be seriously wounded or killed by this attack. High-ranking demons such as the Primordial Demons, however, often display near immunity to the weapon's power, requiring more powerful techniques to kill. The size and length of the blade appears to correspond with the amount of Tsuruko's raw magical power that she poured into it. Due to the blade now being composed of magical energy, Halvanhelev can also be used to channel and amplify spells, increasing their power as they are released from the blade. The sword can also absorb spells to become stronger for short periods of time.

Grandmaster Hand-to-Hand Combatant
Grandmaster Hand-to-Hand Combat: Due to constantly engaging in battle with various foes, over time, Tsuruko become an excellent hand-to-hand fighter utilizing a fighting style that directly complements her Zero Effect; the versatility of which allows her to adapt to any foe and beat them. Additionally, Tsuruko has been trained in boxing by her cousin Marisa, Excellen in the Esper martial art Seiken Accel Blow, her grandfather in the Jigen Haō-ryū and even learned some advanced Rune Knight martial arts techniques from Deen Lhant. Due to her past as a delinquent, Tsuruko is naturally attuned to solving things with her fists and feet, devastating opponents through her sheer brute force and speed, more often than not taking the unsuspecting target by surprise through her sheer skill. Indeed, Tsuruko is renowned throughout the world as one of the greatest martial artists to ever live. Because of her smarts -regarding fighting- Tsuruko shows immense power in the ways of street fighting to those who have the unfortunate fate of fighting her; and she is a highly powerful and fierce fighter; indeed, she is without equal in the forte of hand-to-hand combat. Indeed, as of now, Tsuruko has achieved a peak physical conditioning and prowess, granting her immense reserves of stamina. Tsuruko's incredible skill in unarmed combat is drastically enhanced by her inherent immense strength, giving her the ability to unleash devastating blows with ease. Tending to mix it up in the heat of battle, Tsuruko does not favour either punches or kicks; instead, she uses a liberal application of both, more often than not keeping the opponent guessing each and every time. When fighting opponents hand-to-hand, Tsuruko makes use of her greater speed to deliver fast strikes to her opponents, which either allows her to deliver several strikes in a split second, or to increase the force behind her strikes in order to make her blows even more powerful. For stronger physical strikes, she tends to perform spinning attacks akin to breakdancing to knock her opponents back and to deal more damage.

Generally, Tsuruko tends to keep her fighting style freestyle and improvised; attacking from all angles, as well as in every way possible, in order to overwhelm the opponent with relative ease. While fighting, Tsuruko can also think on the spot, and come up with creative counterattacks against her enemies. She is a master of a wide variety of martial arts, knowing Krav Maga, Savate, Capoeira, Aikido, Taekwondo, Jeet Kune Do, grappling, kickboxing, and Muay Thai—however, Tsuruko simply learnt these alternative fighting styles to prove to people that she could master them all within two years, though she secretly integrated parts of the styles into her fighting style; creating an idiosyncratic admixture of all of the styles. In addition, she has incorporated exotic fighting styles into her combat repertoire, allowing her to mix it up quite a bit, keeping her opponents upon their toes—though she does not actually use any of the techniques, simply adapting the movements of each to form an overwhelming yet seamless martial art without any equal. When in battle, Tsuruko makes most use of her powerful arms and legs to take on her foes, with her specialty lying in punching and kicking moves where she uses her extremely powerful limbs to their fullest.

In terms of fighting style, Tsuruko focuses specially on power and speed, using strong and powerful punches and kicks, such as powerpacked jabs or piercing uppercuts, and slashing kicks and drilling knee strikes, to deal damaging blows to her opponents. Once she catches an opponent in her barrage of attacks, she keeps them trapped by keeping up her strikes, never allowing her opponents a chance to counterattack. For stronger strikes, Tsuruko tends to build up momentum with her limbs by swinging them around, before hitting her opponent with full force. Tsuruko's fighting style enables her to strike her opponent swiftly and powerfully with enough force to knock them a fair distance—and normally, the power of her punches and kicks are capable of triggering a violent internal explosion, which can cause the opponent to explode themselves, ala "you are already dead" style. She is able to quickly close in without revealing any hints as to how she advanced; this is the product of her naturally immense speed that is also augmented by the rockets installed within her feet. Indeed, Tsuruko can easily strike the back of the head from a very close distance completely unbeknownst to the target. With her fighting style, she is capable of dealing a blow to the temple that would crush a man's skull. Tsuruko has easily demonstrated a special method in which to defeat powers of unknown ability and origin with merely her bare hands without any enhancements, deflecting onslaughts of magical blasts with ease, and deflecting spells with the exact same technique, as if she were fighting and disarming an opponent who was well-equipped. All in all, Tsuruko's fighting style turns her into a force of nature itself turning even the surroundings into a raging maelstrom of death and oblivion.

Jigen Haō-ryū Kenpō
Jigen Haō-ryū Kenpō (次元覇王流拳法, Dimension King Style Fist Way): The Dimension King Style is a style of hand-to-hand fighting mastered by Tsuruko and taught to her by her grandfather- it is her signature skill, along with the Zero Effect. It is a fighting style which is considered to be one of the few successful imitations of a Slayer Magic, without the dire consequences that lay behind it, though evidently lowering the power of the overall magic. Dimension King Style is, quite simply, the empowerment of the physical body through the magical essence that is both within, and surrounding it. While the concept sounds rather simplistic, the mechanics behind it are indeed somewhat complex, and thus, the application of the magic is rather difficult for unskilled mages. Dimension King Style is a fighting style that is based on the principle that magic may exist in two forms - particles and energy. These two states of existence, within magical terms, allows for the sheer versatility that exists within magic today. This is displayed quite evidently by magic that uses the physical body - such as High Speed - which utilizes magical particles to achieve its desired effects, whereas the magical energy is used in most elemental magic, resonating with magic residing in the atmosphere in order to conjure its fantastical effects. In both cases, the magic itself cannot be produced within the body and taken outside of the body, as it must have an atmospheric, or bodily medium. However, this trait was annihilated by all forms of Slayer Magic, for they encapsulated biological change in order to allow humans to "seep" out magic from their pores and utilize it to enhance their own physical attributes, strengthening them enormously in comparison to regular mages who generally approach combat from a mid to long range.

Dimension King Style, however, is able to overcome this through the simple understanding and appreciation of theory into application. The amazing power of the Dimension King Style originates from the user's magical energy and relies heavily on the successful execution of powerful strikes achieved through manipulating eternano in order to overwhelm the opponent. By using magic in conjuring with their moves, the user can create unique and dynamic attacks that deal destructive damage on their targets, making the user a fierce force to be reckoned with in combat. A user of Dimension King Style are shown to have eternano pointless against them, as it becomes incredibly easy to dismantle these attacks and use them against their opponent, given they do not surpass the user's own reaction time or power, and absorb them unto themselves; a master is known to be extremely versatile with this. When using Dimension King Style, a practitioner projects their blows using eternano itself as a perfect fulcrum, even if it doesn't belong to them or if it's in the field of the user's magical aura. This makes sure that there's very few chances of any magical defense measures that can hold off the attack—as it witnesses all forms of offense and defense as a singular concept, and thus, it treats the foe's own power as a medium for the attack; the power is pure, and it doesn't feel the need to manipulate and control anything that the user or the foe can utilize. Interestingly, the damage of the user's spells and regular attacks are bolstered based on how much damage the user has taken.

This works by the user subconsciously converting part of the damage inflicted by the opponent into magical energy and accumulating it in the user's body; adding it to their magic origin. The efficiency of this conversion into magical energy raises the more the user's physical strength decreases. The magical energy that was accumulated in the magic origin like this can be used to boost the user's abilities; as such, if the user is damaged to the point of being on the verge of death, possibly an enormous amount of magical energy enough to destroy everything before the user's eyes will be saved up. Essentially, a user of Dimension King Style at near death gains enough extra damage on their attacks to reduce the opponent's survivability by a few dozen percent, in addition to increasing the size of most of the user's moves. Dimension King Style also increases the user's power when they are nearly out of magical power; both these factors combined allow the user more chance to stage a comeback than some other characters. The properties of Dimension King Style act as a double-edged sword however, where the user's attacks are extremely weak when they are mostly fine; as such, the user has to be at high damage percents to fight effectively, where they are then vulnerable to high damage themselves. As such, Dimension King Style is the epitome of risk versus reward. The martial art rewards the user for falling behind and punishes them for pulling ahead, encouraging close battles and come-from-behind victories. It should be noted that Tsuruko's variation of the Dimension King Style uses her Zero Effect in replacement of anything magical related.
 * Dimension King Style: Whirlwind Spinning Kick (次元覇王流拳法・旋風竜巻蹴り, Jigen Haō-ryū: Senpū Tatsumaki-Geri): The first attack that Tsuruko uses with her Dimension King Style; when performing Whirlwind Spinning Kick, Tsuruko jumps and rotates her legs, spinning around at high speeds, causing a slight pull on nearby opponents while emitting a small tornado that devastates everything three meters from all directions around her. If the enemy is caught, Tsuruko's high-powered leg swing keeps the opponent trapped until the move ends. This makes escape via directional influence difficult. While powerful, it is known to be erratic; more often than not catching Tsuruko's foe off-guard while dealing a multitude of strikes; it is enhanced by the wind generated by the spiral formation that she spins around in; and thus it traps foes in a vicious cyclone of kicks which deals up to ten hits while damaging all the foes in the radius of her foot. When Whirlwind Spinning Kick is finished, the last hit dealt causes slightly more than moderate knockback, but can be very dangerous if used in the air, as while descending, Tsuruko is helpless due to the sheer momentum generated by the initial Whirlwind Spinning Kick, which had tired her out, leaving her completely vulnerable. Whirlwind Spinning Kick can be controlled, allowing Tsuruko to move in any direction while using the attack, and moving instead of remaining causes Tsuruko to extend the amount of time that she spins around. While using the Whirlwind Spinning Kick in the air, if all strikes make contact, the final blow is capable of knocking the opponent even higher into the air. This attack can be used for recovery as well. It gains great horizontal distance on top of some vertical distance, especially if she jumps before using the attack. However, something to note is that Tsuruko will bounce off of the ground rather than returning safely if the enemy manages to strike her while they are in the tornado.
 * Dimension King Style: Holy Fist Punch (次元覇王流拳法・聖拳突き, Jigen Haō-ryū: Seiken-zuki): The second technique of the Dimension King Style, the Holy Fist Punch is one of two attacks that involve Tsuruko's fists. In order to perform the Holy Fist Punch, Tsuruko imbues her arm with pure power, before compressing a shockwave upon her fist, condensing it to its utmost limit in order to drastically enhance the power of the next attack; condensing it unto its utmost limit until her hand starts overflowing in pure energy, radiating a power so brightly that it seems to blind those whom turn their gaze upon Tsuruko. Once this is done, Tsuruko cocks her fist back before throwing a powerful straight punch with all of her might, unleashing the concentrated shockwave upon her fist towards the foe, essentially transferring the shockwave into the opponent's body, causing a powerful surge that grievously wounds them from within; the attack is actually derived from Chinese martial arts. The power of the attack is demonstrated upon impact; the shockwave does indeed multiply, causing a number of surreal, delayed shockwaves to smash into the opponent's body simultaneously—the last of which is capable of sending them careening through the air at an astounding velocity; even shattering steel and destroying a small building. The attack is said to be akin to being shot in the face by a gigantic cannonball; devastating the unlucky recipient with relative ease. However, this attack can be stopped if the shockwave cannot travel through Tsuruko's arm or hand, essentially resulting in a blunt strike that, while powerful, does only one third of the damage that it normally would. Interestingly, Tsuruko is capable of turning around to the opposite direction while charging Holy Fist Punch up; allowing the attack to do slightly more damage, but it has a slower release time due to the extra seconds needed to turn around. However, Holy Fist Punch has a simple yet glaring weakness—it requires a precious few seconds to charge up and release, during which, Tsuruko's opponent could attack, thus interrupting the strike. Because of this, she normally prefers to use the technique when the opponent is restrained or unguarded.
 * Dimension King Style: Burst Wave Fist (次元覇王流拳法・波動列帛拳, Jigen Haō-ryū: Hadō Reppakuken): Burst Wave Fist is the third attack of the Dimension King Style- it is also something that is a grave departure from the normal close-combat attacks of the style; being similar to a "ki attack" from fiction. In order to harness the power of the Burst Wave Fist, Tsuruko first forms pure power upon both of her hands, before utilizing her pure power to form a shockwave that is condensed upon both of her hands. Pushing her hands together in a cup-like motion, she cocks her hands back, while applying the theory that "Zero Effect is an invisible force" to the shockwave. After a few seconds of charging, Tsuruko unleashes the shockwave in the form of a powerful concussive beam that blasts through the air at astounding speeds in any direction that she chooses upon release -this allows her to strike more than one opponent with ease-; the attack is shaped like twin dragons. In addition to this, Tsuruko can move faster than the attack itself, allowing her to fire multiple blasts from different directions. Indeed, Burst Wave Fist is capable of travelling great distances in an instant, making it increasingly difficult to evade, though it is at its most powerful at the start; as the generation of the two dragons causes a brief shockwave of power. Interestingly, the Burst Wave is shown to have two settings—a version that emits a higher-velocity beam with enough momentum to breach defenses; but the damage dealt to the target without penetrating a defense is significantly reduced due to its lower power transfer; it will pursue the enemy and surely hit; the other version is akin to a classic beam attack: this variation has less velocity and, while less penetrating, quickly transfers the shockwave to the target upon impact, reverting back to pure power and destroying the target from within; though naturally, this version does not work upon humans. Burst Wave Fist is capable of being charged, and while doing so, any other being, human or not, who touches the blast takes a small amount of damage. Indeed, Tsuruko can also continue to hold the blast after it is fully charged, allowing her to take advantage of its damage dealing ability, or store it for later use. If the enemy attempts to defend against it, Burst Wave Fist is capable of shattering most defenses. The reason that it quickly obliterates any defenses is the amazing speed behind the multiple hits of the charge which quickly wears away at the opponent's defenses. Indeed, it is possible for Tsuruko to constantly fire the blast while approaching foes from the air.
 * Dimension King Style Ultimate Attack: Victorize Kick (次元覇王流拳法・絶招・閃光魔術蹴り (ビクターライズ・キック), Jigen Haō-ryū Zesshō: Bikutāraizu Kikku lit. Flashing Magical Kick): Victorize Kick is known as Tsuruko's signature attack; in addition, it is also the first original Dimension King Style technique that she developed. Victorize Kick is also the "Ultimate Attack" (絶招, Zesshō) of the Dimension King Style- it's Tsuruko's most prominent finishing attack and one of Gaiki's Limit Breaks. In order to initiate this attack, Tsuruko imbues her leg with air pressure, while focusing even more power around her foot; this intensifies the leg, focusing so much power upon her limb that it begins to shine golden. From there, she harnesses her immense speed by kicking off the ground ten times in the blink of an eye –the first kick releases a small shockwave with special properties- in order to leap a good twenty feet or so into the air, before using her speed once more to propel herself downward at an angle at an overwhelming velocity—when in motion, she begins to twirl around while thrusting her leg forward, initiating a corkscrew kick as she drills through the opponent. This attack promises absolute destruction, which is granted by causing friction with the hydrogen in the air by the sheer ferocity of the blow, generating a medium-sized explosion upon impact. The resulting power of the diving kick can crush the target and is particularly dangerous to magic users. It is capable of tearing through diamond and even through weak defenses. Because of the sheer velocity of the move, Tsuruko's movements seem to cause fire to be released behind her figure during her descent; the impact of her body releasing a powerful shockwave of pure power that is capable of destroying everything in the vicinity for meter away from touch-down. However, there is a secret about the Victorize Kick—if the opponent is hit by the initial shockwave of Tsuruko charging her jump, then they will become stunned by falling down, leaving them vulnerable to the rest of the attack with no way to defend against it. The Victorize Kick has the uncanny ability to strike characters who are airborne, even magic users in elemental transformations, but it is rather difficult to actually hit an enemy with it and avoid being struck if the attack misses. Another unique property is that if the Victorize Kick ends with Tsuruko shooting towards a wall, she is capable of instantly bouncing off and gaining height, allowing her to attempt the attack again.

Assorted Other Styles and Attacks

 * Boxing (ボクシング, Bokushingu): Tsuruko was trained in the art of Boxing by her cousin Marisa Sejren during her stay in Luin when she and Excellen took Hikari to the city to purify her from demonic influence gained during her time as a Magic Council captive. While Marisa told Tsuruko that there were many styles of boxing, Tsuruko chose to keep her normal style of combat and apply it to the martial art. Essentially, she took up a "pressure fighter" style; this requires her to stay in close proximity to an opponent, throwing an intense flurry of punches towards her foe and combinations of hooks and uppercuts. The reason why this style is so effective is because Tsuruko is extremely durable; and swarming usually involves being hit with many over and over before the user can maneuver inside where they are more effective. When using boxing, Tsuruko fights best at close range because more often than not, she's generally shorter and has less reach than her opponents and thus are more effective at a short distance where the longer arms of her opponents make punching awkward. Tsuruko often uses her short stature to her advantage, employing a bob-and-weave defense by bending at the waist to slip underneath or to the sides of incoming punches. Unlike blocking, causing an opponent to miss a punch disrupts their balance, permits forward movement past the opponent's extended arm and keeps the hands free to counter. A distinct advantage that Tsuruko has is when throwing uppercuts where she can channel her entire bodyweight behind the punch; her uppercuts hit like a truck; but essentially, the key to Tsuruko's boxing style is aggression, endurance, and bobbing-and-weaving.
 * Shining Heart Overdrive ( 無限光心魂流星拳(シャイニング・ハート・オーバードライブ) , Shainingu Hāto Oubādoraibu lit. Limitless Light, Heart and Soul Meteor Fist): When performing Shining Heart Overdrive, Tsuruko concentrates her Zero Effect into her hands, and suddenly makes the position of the stars of the Phoenix constellation. After this, Tsuruko lowers her stance and central balance to begin with and begins to aggressively weave her body in a pattern similar to the shape of a figure eight, making it increasingly difficult for the opponent to track and trace her movements accurately. By using the power of the Zero Effect, Tsuruko unleashes a flurry of over one hundred punches from left or right which target the opponent's pressure points, which enables her to transfer the Zero Effect that is currently coursing through her body into her opponent with relative ease in multiple locations at high speeds, causing all of her strikes to burn the opponent; it is striking the foe over a thousand times a second, and they are capable of attacking the foe over long distances. She launches this attack while continuing her bobbing and weaving, catching the target in a high paced barrage of punches that few succeed on escaping from. If Tsuruko has a full amount of stamina, more fists may strike, until they reach the speed of light. The fists land so fast that, after a volley, they seemingly connect simultaneously. The massive circles of air bursts from the punches surrounding Tsuruko resemble meteors; bombarding the opponent relentlessly. The sheer force of Shining Heart Overdrive is more than enough to cause a dragon to be blown away by the incredible power of the countless blows, knocking it a fair distance before it quickly melts into nothingness. It is said that Shining Heart Overdrive has the power of the sun itself packed into it, allowing Tsuruko to completely obliterate those with hearts of darkness. What should be noted is that the moment that Tsuruko strikes all of the opponent's pressure points and finishes the attack, she triggers the violent explosion of internal organs so characteristic of her fighting style. When performing the technique, it has a certain incantation; "My heart resonates...blazing through the cosmos...The beat of my blood is razor sharp! Let's do it! SHINING HEART OVERDRIVE!!" (私の心は共鳴する...宇宙を通して燃える...私の血のビートは鋭いです！やってヤルゼ！シャイニング・ハート・オーバードライブ！, Watashi no kokoro wa kyōmei suru... Uchū o tōshite moeru... Watashi no chi no bīto wa surudoidesu! Yatte yaruze! Shainingu Hāto Oubādoraibu!!).
 * Seiken Accel Blow (正拳アクセルブロー, Seiken Akuseru Burō, roughly Proper Fist): Seiken Accel Blow is a style of Kenpo that all Espers use when battling, which is used through better handling of their Esper powers; Excellen Kilekion included. In the style of Seiken Accel Blow, the user focuses on using mostly their arms; rather, every part of their arms to deal immense damage to the opponent. The fighting style focuses on the principles of natural selection: that only those strong enough can survive the harsh and inhuman training while fully mastering Seiken Accel Blow's fighting style. Those that master it obtain their power from the negative feelings of the weak they prey on, making it into Rinki (臨気（りんき）,Confrontation Ki), a form of magic that is the polar opposite of normal martial arts and brought about by the darkness in one's heart, used by the Espers to form techniques. The ultimate form of Rinki is the Dorinki (怒臨気（どりんき）, Angry Confrontation Ki), manifested through infinite rage and a desire to destroy everything. While the art relies on rage, it should be noted that if one focuses on nothing but anger, then their strength will be rather weak. The proper method in using the Seiken Accel Blow is by harnessing one's anger and making it more controlled; thus allowing the user to unleash short bursts of Rinki as the user unleashes immense force to overpower opponents and can also be used to augment the user's own strength; as it is a freeform style which typically has no stances and instead focuses on incredible speed and power. The specials of these attacks are called Seiken Accel Blow Secret Technique (正拳アクセルブロー奥義, Seiken Akuseru Burō Ōgi). While Tsuruko, not being an Esper (obviously), has no access to Rinki and Dorinki, she substitutes those two powers with her Zero Effect, drastically enhancing the power of the art, far beyond a normal Seiken Accel Blow user's power.
 * GaikiMugenAttack.pngRocket Punch (無限伸縮自在拳 (ロケット・パンチ), Roketto Panchi lit. Infinite Telescoping Fist): Rocket Punch is one of Tsuruko's two Limit Breaks alongside Victorize Kick; it is an extension of Seiken-zuki- literally. It involves the use of her Telescoping System—which allows her to manifest weaponry from her body. Through continuous compression of the Zero Effect and the spinning loops of her fist rotating at astounding speeds, Tsuruko compresses the energy around her fist. In addition, Tsuruko condenses the Zero Effect, intensifying the power by convergence and acceleration, turning her fist a scorching purple. Once the energy has been fully charged, Tsuruko performs a powerful punching motion as her upper right arm spins clockwise at high speed while her fist spins counterclockwise, which it then aims and launches at the target—releasing the energy imbued within her fist in a Seiken-zuki- this causes her fist to open up and another arm to extend out of it; with that arm opening up and extending out its own countless times, in a similar manner to a rocket or a chain, launching forward like a missile, punching straight through an enemy before returning and docking with the elbow again. It is noted to be extremely powerful; and it is "Steed, sword, and shining armour in one unified package"; more often than not her finishing blow. The moment that Tsuruko fires her forearm, its intense speed is further enhanced by the arm emitting incredible heat from its thrusters, allowing Tsuruko to smash through even diamond and opposing attacks; crushing almost any type of equipment with relative ease. Indeed, the attack is so fast that it ignites the hydrogen in the air, creating explosions similar to a meteorite catching fire while falling through the atmosphere at twenty five thousand miles per hour. The impact of the Rocket Punch releases oscillatory waves which radiate upon the opponent like a shockwave. The resulting resonance can crush the target and is particularly dangerous to electronic machinery; even capable of affecting nanomachines as well as Driver Belts; it is an attack that deals absolute destruction to opponents. There are at least two variations on this, both used against E in his dragonized form. In the first, the arm is launched first then begins to spin, and in the second, the arm spins against something before being launched. The second was effective against E's dragon scales, smashing through them with ease. The Rocket Punch has also been used on Amadam during the end of S1 in a variant where the fist does not detach at all, instead simply spinning rapidly during a punch. In this version, unlike previous Rocket Punch attacks, Tsuruko simply rears back and punches rather than holding her arm upwards before attacking - this allows the Rocket Punch to be performed much more quickly with little to no telegraphing. It should be noted that with Rocket Punch, Tsuruko's capable of utilizing the Zero Effect in order to grasp the opponent's Magic Origin and nullifying its existence, effectively depowering them. This is a major reason why Tsuruko often opts to utilize the attack over the flashier Victorize Kick, as she can render particularly dangerous opponents a non-threat so they would not be able to attempt to harm innocents or her loved ones again. Multiple Rocket Punches can be chained if several enemies are smashed correctly, either with one carefully-aimed punch or by turning to attack each enemy in turn when surrounded. The Rocket Punch can extend all the way up to the moon in around fifty seconds, meaning that it covers around 7688 kilometers per second- over 2.5% the speed of light. Tsuruko's fight with Phosphor shows that Rocket Punch can extend up into lunar orbit, travel around until it scores a hit then proceed to orbit the planet twice before coming back down without ever detaching from Tsuruko's arm, or her moving a single inch from where she's standing.
 * Electrostrike (エレクトロストライク, Erekutorosutoraiku): The Electrostrike is an unnamed special martial arts move shown by Tsuruko Sejren, mainly in Daybreak's revival as a way to deal with enemies not worth her time. In order to perform Electrostrike, Tsuruko applies pressure with her fingers to the nerves near the base of her target's neck –at the shoulder, releasing a relatively high voltage of electricity from her fingers, delivering an electric current to disrupt the target's voluntary control of muscles causing phenomena called "neuromuscular incapacitation". The moment that Tsuruko touches the target, the target experiences stimulation of their senses and motor functions, resulting in strong involuntary muscle contractions. The Electrostrike also has another function—it enables Tsuruko destroy technology by simply touching it with her hands. It can be conducted along and through almost any surface, including skin, clothes, or layers of those. However, it seems that there are varying degrees to this ability as some opponents have been simply dazed where others have been sent into unconsciousness. This power provides a great advantage as Tsuruko can end a confrontation quickly with little collateral damage; unlike her other attacks, which generally destroy everything that she comes into contact with. It should be noted that on humans, it has an almost hundred-percent success rate—though demons, dragons, Espers, and the Magius have a harder time succumbing to the attack. Generally, the victims of this move tend to suffer headaches afterwards. This attack was derived from the Rune Knight "sleeper hold" technique that's used to quell rowdy crowds.

Expert Swordsmanship Specialist
Expert Swordsmanship Specialist: Tsuruko demonstrates a natural aptitude for the ways of the sword and is able to best her enemies easily; fighting in a style which she dubs My Style (私式, Watashi-shiki). Tsuruko is primarily an instinctual fighter, using relying on subconscious knowledge of traditional yet flashy sword techniques to deal punishing blows to her hapless opponents. Tsuruko has shown great skill in utilizing the reverse-grip of swordsmanship—which is her regular way of holding Dragredder; and she is even capable of employing her sword effectively using her feet, by wielding their hilts between her hallux and second toe; wielding it in a similar manner to breakdancing. Her attacks are so fierce and swift, that her foes rarely, if ever, have the chance to launch a proper counterattack. Her swordsmanship is enough for her to slash with enough force to cause her swings to become capable of slicing through metal using only the air pressure. Her way of swordfighting is completely self-taught, and borrows moves from several others she is in association with. Utilizing sweeping, random movements, upon close inspection, it should be noted that Tsuruko's style of swordfighting is almost, nay, identical to her way of going about hand-to-hand combat, with unpredictability being her greatest asset when forced to pick up a bladed weapon. Many of her attacks are initiated by Tsuruko jumping or dodging before attacking, letting her swiftly dodge enemy attacks and counter with her own in the same movement. Her attacks consist of fast-paced sword combos and powerful kicks, and she is mostly a melee fighter, as most of her ranged attacks are mid-ranged, and she has slow recovery when attacking. As with her hand-to-hand style, Tsuruko's swordfighting is based upon breakdancing, something only her odd mind could come up with, making up her next movements as well as techniques as she fights. Tsuruko has an incredibly aggressive style: she is constantly on the offensive, and eschews any defensive moves in favor of speed and strength, striking heavy and hard while lightning fast. Her power attacks are able to knock her opponents back just through sheer kinetic force, throwing them off balance and leaving them vulnerable to further brute-force strikes and power blows that sought not just to penetrate her opponents' defense, but also to push them back and leave them unable to counter blows; leading her style of battle to be tremendously deadly. However, Tsuruko has always held a greater love for hand-to-hand combat, and seeing that lugging around Dragredder everywhere was tiring, she eventually discontinued practicing swordsmanship in favour of her long love of martial arts. Even though she dropped the art, Tsuruko picked up the Excalibur sword in Daybreak S3 to fend off Itsuka Nightray, showing that nearly a decade of inactivity regarding swordsmanship hadn't dulled her edge.

Physical Abilities
Immeasurable Strength: Tsuruko's strength is a rather important aspect of her fighting style, and one of the most notable things about her; the sheer amount of strength she has can be considered being akin to a power that could shatter the world. Indeed, due to her origins as Deus Machina Number Three, she is made of an unidentified alloy mistaken by many as Orichalcum- it's a one-of-a-kind meteoric ore, theorized to be of extraterrestrial origin. Dzerve later clarifies that the alloy was derived from the Catalyst Comet, which brought the zero particles (and derived from it, eternano and magic) to the Old World before the world was rebooted into Earth Land, Edolas, and Aether. The alloy is unbreakable under any circumstances; indeed, even a small chip of the alloy is shown to be capable of surviving numerous nuclear explosions, while sustaining absolutely zero damage. Because of its composure, the alloy, whether blunt or sharp, is capable of smashing through or slicing through almost any known substance, with Soul Metal and Devius' nanomachine armour being an exception. Most notably, the alloy is capable of tearing through any sort of magic like a hot knife through butter, further augmented by the Zero Effect, enabling Tsuruko to effectively terminate the threat of magic.

In any case, due to Tsuruko's construction materials and numerous other factors, she is effectively the physically strongest character in the Sun Trilogy, especially after Daybreak S3, where Tsuruko has no real competition regarding the title. The exact limitations of Tsuruko's strength is indefinable, but she is capable lifting far in excess of twenty-four tonnes—indeed, her "normal" punches and kicks are said to have the force of twenty-four tonnes behind them—her exact weight. Indeed, because of this, she's capable of effortlessly defeating powerful monsters and villains, with a single, nonchalant attack. Due to the sheer force behind all of her blows, many enemies simply explode violently the moment that Tsuruko's unarmed attacks come into contact with them- this is because her strength enables her to split the hydrogen in the air. Her inherent immense power is only amplified by the momentum at which she moves; making her strong enough to smash her way through enemies and, as said before, almost any material, destroy surfaces by stomping, or break down solid walls; and she is able to lift and press many times her own weight. Because of her strength, Tsuruko is also shown to effortlessly destroy buildings with a single strike; and by simply stomping upon the ground, she's capable of splitting the earth before her into an enormous chasm. Indeed; Tsuruko is capable of smashing through solid Orichalcum and the scales of a dragon with a single unarmed blow; and her attacks are able to release shockwaves with every impact. Her power is more than enough to catch a sword strike between two of her fingers –even when the sword is made of Orichalcum-, even overpowering the person swinging the blade with relative ease. Tsuruko's jaw is powerful enough to bite through and shatter numerous types of metal—on many occasions, she's shown to simply chomp down on various swords and break them, even the legendary Excalibur which was said to rend heaven and earth with its sharpness.

Tsuruko's inability to fly is somewhat compensated for by her ability to use her strength to leap tremendous heights and distances; the initial limits of which 'simply' allow her to touch the skies in a single bound. This can be shown in a more mundane manner by her smashing her head through the upper floor of her dorm room in La Pucelle in order to tell Kaguya something. Another notable instance of this is during the Constellation Skirmish, where Alexis Tenjouin attempted to fire upon the hideout of the Zodiac Knights with the Etherion satellite. In order to prevent her from doing so –as the blast would wipe out Hargeon as well-, Tsuruko launched herself from the rooftop of La Pucelle, soaring into the sky and smashing right through the barrel of the satellite before tearing the Etherion apart with her bare hands from within- another thing to look at is that just by leaping off of the building, she accidently crushed it due to her immense strength. However, all of these examples pale before Tsuruko's fight with Devius in Daybreak S3—when Tsuruko was launched from the Old World to the Moon by Devius' Nanorage attack, she utilized her immense strength and channeled it into a jump that enabled her to return to the Old World in a fraction of a second- upon landing, the sheer force generated by her impact caused an enormous shockwave that devastated a city and immense tremors shook the world. Another thing to note is that Tsuruko can throw objects through the air with such force that she can set them aflame through sheer friction.
 * Tsuruko_-_Magical_Aura.gifStrength Control: An important part of Tsuruko's powers- no, her daily life- is the ability to properly moderate the amount of strength that she properly exerts at any given time. Willingly or subconsciously –the distinction is never really made-, Tsuruko places limiters upon her body that, well, obviously, limit her physical strength- this removes the possibility that she could kill somebody by complete accident. This is done by using her Zero Effect to affect her limbs—the Zero Effect nullifies and negates any phenomena, and Tsuruko's strength is considered "superhuman". This enables her to interact with her surroundings casually- almost as if she were a completely normal, ordinary young girl. This is essential for her own sanity—all of her life, Tsuruko has had the subconscious fear of being "different" from other people (in this case being something straight out of a super robot show anthropomorphized as a cute girl); and the mere thought of accidentally killing somebody due to her strength has scared her stiff on numerous occasions before developing this technique. In order to release this technique, Tsuruko simply wills it, either with voice activation or thought, causing the visage of light shards shattering around her limbs to appear- this is simply formed by the Zero Effect for drama's sake- as Tsuruko loves putting on a show. The release of the limiters tends to cause a shockwave to erupt from her body- specifically her feet. This devastates the vicinity and causes an upsurge of sheer power that takes the form of a jagged aura of pure energy emanating from her very person. As a side note, if Tsuruko is struck by outside forces in this "state", her body is treated as if she were in her "normal state". Indeed, once her limiters are removed, Tsuruko is ready to annihilate her opponents in the blink of an eye.

Hypersonic Speed: Another one of Tsuruko's most notable features is her law-defying speed—that is to say, it's in a class of its own. Because of the miniaturized rocket boosters installed in her feet and legs, plus her own natural strength, Tsuruko has shown the ability to instantly accelerate to and move at speeds far greater than mach speed (which is approximately seven hundred and sixty-eight miles per hour); indeed, because of this amazing swiftness, users of High Speed, Slowing Magic, and any speed-enhancing power, whether it be magic, Curse, or anything else, are shown to be considered akin to snails in regards to her own movements. It is notable that Tsuruko is capable of dashing backwards at full speed just as proficiently as she is dashing forwards—she maintains full control of her speed all times, capable of turning and breaking on a dime. Indeed, it's said that on her first day during Physical Education at La Pucelle, Tsuruko completed a one thousand, five hundred meter dash in the blink of an eye. Tsuruko's capable of scaling right up vertical surfaces and ceilings, sprinting on water (like a certain famous mythological figure, suspiciously enough), smash her way straight through anything in her path, and even move at such a speed that the ground explodes in her wake. On a more humourous note, after accidentally dropping a sandwich that Excellen made her for lunch out of the school window, Tsuruko quickly ran down the building, saving it, and leaping back up said building without anyone (sans Giselle) noticing that she had done such a thing.

Tsuruko has shown to be capable of effortlessly out-speeding Elsie Albion, one of the Four Heavenly Kings, whose spell, Shinsoku, supposedly enables her to move at near-light speeds- she countered the spell just by hopping side-to-side. While Elsie created twenty shadow clones with speed, Tsuruko created infinite clones with side hops. What brought Elsie down was the shockwaves of Tsuruko's side-hops. Indeed, during the Constellation Skirmish, Tsuruko showed the ability to move several times the speed of sound- when facing Joker, she went three rounds with her in less than thirty seconds over the right to activate the Magic Draining Bomb- which would remove magic from the world, obviously. During their clash, Joker made the observation that Tsuruko kept getting "faster and faster", going from "supersonic", which is nine hundred and fifteen miles per hour to three thousand, eight hundred and fourty miles per hour, to "hypersonic", which is three thousand, eight hundred and fourty miles per hour to seven thousand, six hundred and eighty miles per hour. In another incident, during her final battle with Amadam at the climax of Daybreak S2, even he, with his precognition and super senses (plus hypersonic movement) couldn't react to her actions, and an onlooking Gary noted that she seemed to be moving at faster-than-light speeds—though this couldn't be proven. In any case, her immense speed and swift reflexes enable her to react to situations without causing civilians undo stress. Normally, Tsuruko has shown the ability to create sonic booms when in motion –each step upon the ground unleashes one-, though if sprinting for long distances, she use a mild form of her Strength Control ability to prevent the sonic booms from being released by her movements to avoid collateral damage and civilian casualties.

Going further, by maintaining full control over her speed, Tsuruko is capable of utilizing its potency to its full utility in any kind of environment (even in the air, beneath the ground, or underwater), tying her speed into her fighting style, utilizing it for overwhelmingly swift offense and defense. Indeed, Tsuruko is not only capable of running at maximum speed in straight lines, but also in full tight circles and through sharp turns with complete control over her momentum- she's shown the uncanny ability to avoid obstacles and unintended targets. Tsuruko has been shown to be able to evade many a combatant in both long and close-range; her movements are so tremendously swift that few would be likely to see an attack take place—this enables her to attack almost a multiple of thirty times in a row per second. Tsuruko is amazingly well coordinated, as she is able to catch bullets in mid-air; her tremendous reflexes, agility and speed usually enables her to dodge many a powerful projectile while balancing herself on one hand. Tsuruko reacts so swiftly to current events in her battles that it seems as if she has a sixth sense of sorts; even being able to react to attacks before they're released; it has been shown time and time again that Tsuruko's reflexes enhance her speed even further, to the point that it seems as if Tsuruko has the ability to teleport with every movement that she makes. She is also incredibly precise, as she is able to remove small objects from a person's skull without damaging the person's brain in any way. Due to being so small and spry, Tsuruko is highly flexible in battle- able to perform one-handed backflips, somersaults, and mid-air cartwheels with little effort in terms of physical strain. She's also capable of applying her speed in combat or for other maneuvers such as healing herself by vibrating her body, or launching shockwaves by spinning at high speeds. In addition, her amazing speed allows a limited form of aerokinesis by creating tornadoes and blades of wind with her high-speed movements.
 * Self-Styled Instant Movement Technique: Showtime Sprint (自流瞬動・ショータイム・スプリント, Jiryū Shundō: Shōtaimu Supurinto): The Self-Styled Instant Movement Technique: Showtime Sprint is Tsuruko's preferred method of movement throughout the Sun Trilogy. It was invented by her entirely by accident during her second fight with Kirika Hotsuin after awakening her Soul Armour in Showtime—during the fight, in the opening moments; she dashed forward with a mind-blowing speed that obliterated the surroundings with a sonic boom. The technique is said to be the highest speed that one can achieve—even faster than High Speed or Slowing Magic, and it is often touted to be the "supreme form of ultimate speed"—notably, only Tsuruko can utilize it. This speed is noted to be something completely different than mere speed-enhancing techniques; in fact, it is said to be akin to a form of teleportation. On rare occasions, the technique is misguidedly compared to the likes of the speed of light, though this is completely inaccurate; but it allows Tsuruko to move faster than the eye can follow with a short burst of super speed that gets used more like teleportation. By kicking off a thousand times in the blink of an eye, Tsuruko gathers additional kinetic energy within her legs in order to enhance her already tremendous speed, drastically boosting her movements exponentially while creating a sonic boom. The movements of the technique make it seem that the positions of Tsuruko and her targets have been reduced in a flash through her amazing movements. When utilizing the technique, Tsuruko releases a fair amount distinct noise when in motion, and on the ground she leaves small craters in her wake with every step that she takes, and midair the surrounding atmosphere around her ripples as though from waves of heat with an occasional discharge of electricity; leaving afterimages as she moves. Each of these afterimages are accompanied by incredibly powerful razor-like winds that possess the power to leave shockwaves that will devastate the area. A side effect of her extreme speed, Tsuruko can produce afterimages of herself in order to confuse opponents who are unable to follow her movements. While she does have control over afterimages, Tsuruko usually moves so quickly that she creates afterimages inadvertently. In nearly every fight she's been in, she has used an afterimage to fool her opponents into thinking they have killed her in one blow, only to appear unharmed somewhere else and land a decisive blow. Her afterimages are shown to be tangible as a result of her speed. This speed can be put to an offensive use by Tsuruko putting her weight –an entire twenty-plus tonnes- into the technique, essentially turning herself into a cannonball that bounds around at amazing speed. After it, Tsuruko will then fall back on the ground and start running normally with streams of air released in her wake. While active, the technique gives Tsuruko increased speed and invulnerability, allowing her to damage enemies and opponents simply by running into them. However, the technique has a weakness; when performing the technique, it is extremely difficult to see her destination, though not impossible—but it requires amazing reflexes and split-second reactions in order to use properly; making it a 'high risk, high reward' ability. This technique has never really been named; but rather, it is the constant movement that Tsuruko makes with her Soul Armour equipped, implying that the two are tied somehow.
 * Overdrive Bullet (オーバードライブ・バレット, Ōbādoraibu Baretto): Later, it is shown that by overloading her circuits, Tsuruko can achieve four times the accelerating speed of her previous speed, allowing her to reach speed reaching that of Mach 9. This technique is known as the Overdrive Bullet, and when performing the technique, Tsuruko speeds up considerably and can reportedly penetrate any substance she comes in contact with, albeit only for a short time. When performing the Overdrive Bullet, Tsuruko begins to overload her circuitry. When this happens, blue sparks emit from her body and a chemical reaction which forms the Overdrive Bullet is triggered. Tsuruko then forms a destructive energy field around her body that can burn through or penetrate any substance, and shoots herself forward are four times her own, already high, acceleration, allowing her to pierce through any substance in her way; and she flies the target at incredible speed, resulting in a quite devastating impact that can destroy creatures such as Overlord-class symbiotes; it also allows Tsuruko to move at such a speed that the human eye can no longer track her. Performing this spell also appears in certain situations to make Tsuruko unaffected by attacks: it allows her to pass harmlessly through most magical attacks without any side effect, and it can also carry the effects of her Zero Effect- which destroys anything related to magic upon contact, allowing her to harness the power of Overdrive Bullet for a longer duration. When she has gained enough speed, she will gain a blue, funnel-like aura. The drawback of the Overdrive Bullet is that it cannot be sustained for extended periods of time, since its unfavourable performance cost has Tsuruko strain her circuitry beyond its limits, and could potentially destroy Tsuruko herself—Giselle had told her that she could only use the Overdrive Bullet a grand total of three times; and on the third time, her circuitry would overload, killing her in an enormous explosion. Because of this, Giselle attempted to immediately remove the function twice; the last time without Tsuruko's knowledge when she was sleeping, but Tsuruko convinced her to allow her to keep the Overdrive Bullet, as she would need its overwhelming power to defeat Amadam.

Diamond-esque Durability: What finalizes Tsuruko being a force of nature in combat is the fact that she's damn near indestructible. Because of the unidentified completely invincible alloy she's composed off, Tsuruko's capable of withstanding high-power blows from extremely powerful beings such as Mr. E in his dragon form without taking a scratch or feeling any pain; first showcased in Dragon Drama. Because of her indestructible alloy, Tsuruko is largely immune to different forms and levels of lacerations, blunt force trauma, falls from great heights, explosions, the cold void of space, toxins and all known diseases in all three worlds. In addition, what she can't handle the Zero Effect does for her- as "phenomena intervention" also includes supernatural abilities and the like. She has been sent crashing through a wall and landing without a flinch or a minor injury, suffering no damage at all from a Wizard Saint-level foe's attacks, continuing to fight as if nothing happened, displaying an incredible amount of resilience. She can survive getting caught in the crossfire from all angles by heavy machinegun fire, and merely shrugs it off; and she can smash spires of Orichalcum with her fist without showing any sign of pain or injury.

It is also worth noting that, for nearly all the battles Tsuruko has endured, she has never been crippled, nor has she displayed any serious injuries. She can take a lot of major punishment in battle before she starts to wear down. Even after receiving major damage, Tsuruko displays a remarkably fast recovery rate from damage, allowing her to quickly re-enter a battle after just a few moments. In addition, Tsuruko is perfectly capable of breaking free from any sort of obstruction that threatens to bind and constrict her, preventing her from moving, making her all the more deadlier. Additionally, she can survive free-falls from relatively impressive heights, falling face-first from a high point in a fifty story building, merely shaking it off after landing. This level of durability is how she survived other forms of extensive punishment, such as falls from several stories like when she landed on a vehicle from six thousand feet with no discomfort- another thing to note is that during her fight with Devius in S3, after being sent crashing into the Moon due to his Nanorage attack, she returned with little to no damage from leaving and entering the Old World's atmosphere- only her clothes were burnt. It has been shown that, despite the dangers of holding ones breath in space, Tsuruko is able to do so with no negative effects on her body.

Regarding the Zero Effect, the power acts as an invisible force-field emanating within a few millimeters from her skin; thanks to its power of "phenomenon intervention", things such as Magic, Curses, and anything regarded as "supernatural" are met with the fate of vanishing into thin air—essentially, everything from the mystical side of superpowers is rendered null and void. They simply disappear in a flash of lilac; the particles that they were composed of scattering to the winds in an instant. Tsuruko can willfully utilize the Zero Effect to a greater degree to provide an additional defense against certain levels of physical and supernatural attacks for a considerably short period of time, but doing so can endanger her should the attempted feat prove inefficient for any reason. Tsuruko has been shown to survive the blast of nuclear warheads; and she can survive the impact of an exploding sun during her battle with Devius. But scaling back for a moment, it's relatively easy for somebody to break their hand by striking Tsuruko if they're not sufficiently prepared or strong enough—as demonstrated when Kaguya attempted to slap her for not taking study seriously, for which Tsuruko apologized for. Adding onto this, because of Tsuruko's indestructible frame, she is considered near impossible to properly harm.

Other Abilities
Low-Level Intelligence: Let it be stated clearly and bluntly; Tsuruko Sejren is not a smart woman. In fact, her younger sister Hikari Zanna, whom is around half her age and in the single digits during Daybreak, is far more intelligent than her. Part of this can be attributed to her loathing of studying- however, it isn't as if she isn't intelligent in other areas, just not book-smart. Tsuruko considers half marks on a test the highest score she's ever received- and even then the teacher adjusted it from eighteen, partly as an expression of his gratitude for Tsuruko saving his wife from a symbiote. In another display of dimwittedness, Tsuruko is shown to struggle with primary school-level math problems, and she has stated that she has problem with complicated words. In fact, it is heavily implied throughout the story that Tsuruko is borderline illiterate; hence why she often asks others to read things for her, though in many of those cases she is preoccupied with something else. However, it is shown that Tsuruko is smart in her own, unusual way; she's a lot more perceptive than her hyperactive, childlike behaviour suggests—she does very little without logical consideration, and in fact points out reasonable flaws in other people's arguments. In fact, a lot of people aren't really sure if Tsuruko is a "really smart person" or a "really dumb person". A compelling argument for the former is the fact that she has a superhumanly good judge of character most of the time—she's normally capable of seeing the inherent goodness in a majority of people, and she's able to see their "true selves" if they're putting up a façade or something along those lines.

Even so, in battle, Tsuruko appears to be able to determine the pattern of her opponent's battle methods and correctly deduce a proper counter to defeat her opponent's attacks. However, this smarts applies to certain subjects, i.e. the things that interest her; which isn't very much due to her narrowly defined interests. She has a great talent for analyzing and observing everything in her presence when in battle. While it is obvious that her intellect does not extend to her piss-poor knowledge of behaviour of other beings -either because she possesses horrible social skills or everyone around her needs to see a shrink- in regards to minor things such as little bits of trivia about the most random of subjects. Despite her supposed disregard for strategy of any kind in her battles and her self-admitted aversion to thinking during battle, being given the name "battle maniac" because of it, Tsuruko is a very insightful person, regularly showing more understanding of many a situation than anyone would ever expect from a person like her. One of the major reasons why Tsuruko is such a deadly foe is because she possesses a high amount of perception when it comes to training, despite loathing participating in training and becoming sick at the very thought about it. Tsuruko learns through her body; usually, she doesn't understand any explanations, so her tutors more often than not decide to force her to experience the technique she is meant to learn first-hand by smacking her around with it. This way of learning has proved extremely effective, to the point that she can learn even a master-levelled technique after being smacked across the head with it ten times.

Zero Effect
Zero Effect (事象干渉 (ゼロ・エフェクト), Zero Efuekto lit. Event Interference) is Tsuruko's sole ability—it's unique to her and her alone. The Zero Effect is referred to as the "Power Beyond God" (以神力, Ishinryoku) by individuals such as Devius and Dzerve, the latter of whom created it. The Zero Effect first came into existence when the Catalyst Comet crashed upon the Old World- the comet's impact upon the world caused the spread of zero particles on the planet. Dzerve Sejren engineered the Zero Effect in order to use it to cure disease and natural disasters and installed it within her magnum opus, Deus Machina Number Three, but Klaus, her partner, reverse-engineered the zero particles to transform them into eternano and thus magic, granting him the ability to cast spells—his plan was to originally become a "god" and unite the world under his rule. However, Dzerve used the Philosopher's Stone –carved from the remains of the Catalyst Comet- to reset the world before he could do so, splitting the Old World into Earth Land, Edolas, and Aether. While the Zero Effect was thought to have vanished along with the previous world, it later resurfaced within Tsuruko- as a child, Tsuruko was suffering the incurable disease that Aigrette Tenjouin succumbed to, and in an effort to save her, Giselle converted her into Deus Machina Number Three from the blueprints that Dzerve had left behind. However, the Zero Effect did not awaken within Tsuruko until she had utilized her Deus Machina form for the first time within Daybreak—the activation also eliminated her magics; leaving her unable to use magic in any way, shape, or form.

In any case, the Zero Effect is an unfathomable power beyond any other, and it's stated to be a power born from the ability to hold true to one's convictions no matter what. Tsuruko, while initially not understanding the power, referred to it as her "Showtime Spirit" (ショータイム・スピリット, Shōtaimu Supiritto); something that Tsuruko considers to be among the most important things her father ever taught her. She originally believed that its power originated from her determination- something that actually isn't too far off, actually. The Zero Effect's power is to destroy supernatural phenomena; essentially enabling Tsuruko to negate anything supernatural such as Magic, Curses, and even to Dzerve's admittance, the power of an Exalt. More specifically, it is a power that can only exist within Tsuruko Sejren's soul due to her being the only person who can harness the zero particles. Neither magic or anything supernatural in the current universe, the Zero Effect is speculated to be of extraterrestrial origin, with only a few people such as Dzerve and Klaus knowing fully of what it entails. It is noted that the Zero Effect is the collection of the hope and the fear of mankind; it is the reference point or template to the original world. Its destruction of magic returns the world back to normal before the magic occurred. As such, the Zero Effect embodies the hopes of those who can act all they want without fear of losing the original world, and is the fear of magicians because it removes the distortion they have created. It acts as a lifeline that allows the world to be reverted to how it was before the Philosopher's Stone split it into three, no matter how far it has been distorted in any direction.

In her message to Tsuruko, Dzerve stated the Zero Effect "... ain't good, but it ain't evil either." In practice, the Zero Effect enables her to resist and override supernatural phenomena by sheer force of will, imposing her own willpower upon on the world- essentially; it is the ultimate manifestation of her unwillingness to give up no matter what. This comes in handy for say, surviving being impaled by a weapon explicitly designed to destroy things dealing with the supernatural. Numerous people comment that the Zero Effect doesn't make any logical sense—as it defies any explanation and the laws of the universe. Indeed, chronologically, the first activation of the Zero Effect was against Kirika Hotsuin in Showtime, where Tsuruko activated it unconsciously—the Zero Effect, paired with her Soul Armour, Gaiki, were more than enough to send Kirika packing; however, the stress of activating it sent her into a coma for a week. Originally, even after awakening it, Tsuruko had no control over the Zero Effect and couldn't activate it- however, during the Dracolich's attack on Luin during the Esper Excellen Part II arc, she utilized consciously it for the first time, erasing a dragon's roar attack from existence. The Zero Effect activating it signified by a glittering purple glow emanating from Tsuruko's figure- this is an "aura" of lilac that is mainly focused upon her arms and legs—indeed, it only works if it comes into contact with her limbs, so if a power hits somewhere besides her limbs, then it has the possibility of causing harm to her. Essentially, in order to negate something, Tsuruko has to come into contact with it. This function has come in handy when fighting teleportation users or armament-type magics—Tsuruko is capable of grabbing them mid-movement, rendering them vulnerable to her next attacks.

It should also be taken into consideration that the purple energy that the Zero Effect takes the form of is completely malleable, when one's willpower is used to manipulate its structure, it can be utilized either in an energy-like state or moldable solid that resembles crystal or glass, that will eventually dissipate or seemingly shatter. Due to the high amount of strength and energy it possesses as well as it's tendency to be sharply shaped when conjured, it can be used as a dramatically impressive weapon, defense, or even energy blasts; essentially as a form of energy that can be utilized similar to the elemental magics- though its natural properties makes it far more effective than anything of the sort. While powerful, Tsuruko rarely utilizes these properties as she finds it far more effective to get up-close and personal with her opponents, though she occasionally uses this aspect of the Zero Effect in order to launch close-range energy blasts that overwhelm the opponent and negate their spells. Another use of this power is to send the purple energy through the ground, allowing it to erupt as spikes of energy for defense and offense—essentially, Tsuruko is capable of sending the Zero Effect through land, sea, sky, and space- as long as she can reach it, the Zero Effect can be utilized there.

However, for all of its law-defying power, the Zero Effect does have quite a few weaknesses. For example, despite of the extents of Tsuruko's abilities, she does not have the ability to negate all "artificial" supernatural abilities, such as the Power of the World and the Dragon's Veins. Some objects, such as the Archangels summoned by Elsie Albion and the Enderdragon require Tsuruko to target the core or some other important piece that provides power to them in order for the Zero Effect to effectively negate them. In addition, the Zero Effect also negates Tsuruko's luck- this is the reason why she gets into so much trouble in the first place- and it causes her to be classified as a non-magician because her power can't be detected by normal means, and is hardly useful in mundane situations, either; hence why she developed the Strength Control "technique". Even more unfortunately, the Zero Effect negates any and all supernatural phenomena, as stated above, so it naturally effects even helpful phenomena, such as a Healing Magic, and Telepathy cannot reach her unless it's done by a Magius such as Giselle—and in this case, it's considered akin to hacking Tsuruko's audio receptors instead of true telepathy. Lastly, it's impossible to use teleportation magic upon her, thus denying her the chance to be teleported to safety.

So far there are only a few attacks which can "surpass" the Zero Effect's power negation speed; as such Tsuruko is unable to completely destroy them despite continued exposure to the Zero Effect. A good example of this is Amadam's Saint Oratario spell; which is an enormous beam of energy that is held for around ten full seconds—Tsuruko would be capable of nullifying the attack for at least five of those seconds, but eventually the sweltering heat emitted as a byproduct of the spell would overwhelm her and knock her back. However, Camilla's All-Dimensions Sever spell is a different case, as it does not fall under the 'surpassing cancelling speed' category, but 'After this window of opportunity it can't be negated' category- as after a few moments, the phenomena that the spell is becomes a part of nature and is no longer considered a supernatural phenomena within half a second. However, she later on learns that even though the Zero Effect cannot instantly negate very powerful attacks, then this means Tsuruko can use her hands to catch very powerful attacks and throw them back at the opponent; essentially taking advantage of a weakness. This is best shown during the final fight of Dawn –Tsuruko vs. Chakravartin-, where Tsuruko yanked one of Chakravartin's exalt wings to throw the Exalt of Edolas off-balance; the single touch negated her kinetic and magical energy absorption as well.
 * Divide Zero (暁光線 (ディバイド・ゼロ), Dibaido Zero lit. Daybreak Beam): Divide Zero is Tsuruko's most basic attack with the Zero Effect- however, due to her distaste towards ranged attacks, it rarely sees any use aside from being used in close-range or as a surprise. When preparing to unleash Divide Zero, Tsuruko focuses intently- bringing her Zero Effect to the forefront, she shapes it into a tangible form- a glistening purple aura. She holds her hands in a cupped position at her side, intensifying the inherent destructive power of her Zero Effect, intensifying the kinetic energy that is about to be released by convergence and acceleration, Tsuruko thrusts her hands forward, unleashing a powerful beam of pure energy that erupts outwards and "purifies the very soul", releasing it as a flash of light; a surging wave of the Zero Effect that was conceptualized for the simple purpose of absolute destruction. The power, speed, blast area, force, and size of the attack is far beyond any other application of any projectile; to point of seriously harming an Overlord-class symbiote, which are stated to be impossible to harm unless their opponent is an exalt. Tsuruko can use this technique in several different manners, such as firing it at the ground to create an omnidirectional blast to knock away incoming attacks or punching at the ground to upturn it and crush everything in its path; as well as keep it imbued within her fists to augment the power of her blows. It can be charged, and while doing so, any other fighter who touches the sphere takes a small amount of damage. Tsuruko can also continue to hold the sphere after it is fully charged, allowing it to take advantage of its damage dealing ability, or store it for later use. The sphere charges relatively fast, around one point five seconds. When fully charged, Divide Zero travels in a straight line but when fired without charging flies in an up-and-down wave motion. As Divide Zero travels towards its opponent, the effect of the Zero Effect ensures that even the people and object outside the attack are affected, incapable to act. The whiplash of the attack can be quite huge, usually blowing apart anything behind the user at the time of attack. The beam is powerful enough to strike multiple enemies and even two adjacent foes simultaneously while its mere presence covers any exposed darkness in light; violently pushing the intended opponent and objects around them away from Tsuruko with overwhelming blunt force. As per its origins as a part of the Zero Effect, the attack creates a positively enormous EMP-esque effect which can stop the heart-beat of living beings, disable all Magitek within the area, and even eradicate any magic within the vicinity.

Soul Armour
Soul Armours (神鎧 (ソウル・アーマー), Sōru Āmā lit. God Armour) are specialized armours worn by various powerful warriors known as Soul Armour Knights (神鎧纏最高戦士 (ソウル・アーマー・ナイト), Sōru Āmā Naito lit. God Armour Clad Supreme Warrior); they are human or humanoid warriors who transforms from a natural human form using a Driver Belt into a superhuman form clad in the armour. The Knights secretly patrol their respective territories to protect civilians from demons. Armed with special magical equipment, the knights carry an eternal war to maintain the light over the darkness in the realm. When transforming into Gaiki, Tsuruko slips the Victory Ring upon her finger, and scans the ring over the Phoenix Driver; causing the belt to expand around her waist like a deck of cards wrapping around. When this is done, Tsuruko throws her right arm at a diagonal to her right then rotates it clock-wise until it is a diagonal to her left, then she retracts it to her waist and thrusts out her left arm at a diagonal to her right. With this, the Phoenix Driver releases a glyph of pure power before her, blasting any opponents in close vicinity away as the woman's speed picks up- running through the series of cards, as she leaves the projections, everything about her changes completely. She becomes Soul Armour Knight Gaiki (神鎧纏最高戦士 (ソウル・アーマー・ナイト) ・凱輝 (ガイキ), Sōru Āmā Naito Gaiki lit. God Armour Clad Supreme Warrior Shining Victory).

Star Phoenix
Star Phoenix (スター・フェニックス, Sutā Fenikkusu): Star Phoenix is the form of Tsuruko's inner demon, known as Phoenix, after she managed to hold on when she was in deep despair and pushed Phoenix back inside, allowing her to use magic. Star Phoenix is a European phoenix-themed demon that came from Tsuruko's soul; its body mostly retains gold and silver colours. He also has a red diamond in his head. Star Phoenix's human form is that of a young man with a grin on his lips. His hair is an unnatural red, his skin pale as though he hasn't seen the sun in a long time, and his eyes are a blazing crimson, far brighter than his hair. The whites of his eyes are black, just like other symbiotes; rather beautifully handsome in his own right. When Tsuruko was still young, Star Phoenix, in his larvae stage, was transferred from Alphonse to her during her birth—by complete accident. Incidentally, Star Phoenix attempted to befriend Tsuruko, teaching her magic as well as basically filling in the gaps of her not having an older sibling. However, once Giselle learnt of their relationship and feared for Tsuruko, she took matters into her own hands, skewering Star Phoenix and keeping him dormant in his larvae stage until the Sabbath; and it is because of this that the demon became vicious and sinister.

Star Phoenix first appeared in The Sabbath ritual, where he was about to burst out from Tsuruko's body. However, Tsuruko managed to keep her symbiote inside of her, saving Tsuruko from the demon. After that, Tsuruko is able to use magic to tame Star Phoenix. However, when Tsuruko is in a crisis because she could not defeat Kirika to protect her friends, Star Phoenix offers Tsuruko his powers. However, Star Phoenix warns Tsuruko if she uses too much of his power, Tsuruko will be driven to despair and Star Phoenix will kill Tsuruko. Tsuruko gives the dragon a very surprising response, saying that Star Phoenix is her hope. However, when Star Phoenix gave Tsuruko access to Soul Armour Gaiki, Star Phoenix still showed his sinister side. He stated that he would like to see which is stronger: hope or despair.

As for personality, Star Phoenix is shown to be extremely hot blooded, as shown when he brutalizes Alexis in a reckless manner. He will kill Tsuruko at any cost if there is a chance. Though Star Phoenix is somewhat sinister, he was shown to have a kind heart. This is shown when he sacrificed himself to protect Tsuruko from Amadam's attack at the end of S1. After Tsuruko's strong heart revived him, though, he regained all of his old memories and had decided to become Tsuruko's hope, in a unique reversal of Tsuruko's declaration to him during S1.
 * Instant Summon: When inside somebody's mindscape, or when fighting particularly powerful opponents, Tsuruko is capable of summoning Star Phoenix in order to aid her in battle with the Stellar Ring, or simply by concentration if Tsuruko is in an eternano-dominated environment while acting as Soul Armour Knight Gaiki. But care must be taken, as Tsuruko is only capable of accessing the power of Star Phoenix when acting as Gaiki—and because of this, if Tsuruko calls upon Star Phoenix through concentration, the Soul Armour will be disengaged and returned to the Phoenix Driver for the duration in which Star Phoenix is out and battling alongside his master.
 * Phoenix Armaments: Later, when Tsuruko confronts Star Phoenix within her mind and asks for her power, Star Phoenix decides to help after seeing his host's resolve and helps Tsuruko obtain the power needed in order to become Soul Armour Knight Gaiki. When Tsuruko is fighting as Soul Armour Knight Gaiki, at choice intervals, a single component of Star Phoenix's body is capable of being manifested upon Gaiki's own body; allowing Tsuruko to use the power of that component to its fullest extent—more often than not, serving as the deciding blow in every battle. However, Star Phoenix told Tsuruko that if she overuses the Phoenix Armaments that this deal had netted her, Tsuruko will fall into deep despair and will kill her and take over.
 * Phoenix Skull (フェニックス・スカル, Fenikkusu Sukaru): The Phoenix Skull is a powerful special technique of Tsuruko's when harnessing Star Phoenix's power while acting as Gaiki; when utilizing it, she gathers magical energy within her chest, which Star Phoenix. Merging his own magical energy with the magical energy Tsuruko has gathered within her chest, he then uses the dual energies to serve as a fulcrum—manifesting his true form's head, a phoenix skull, outwards from Tsuruko's chest. The head is a menacing black in texture, with crimson and golden eyes that stare deep into the souls of their enemies. From there, the fearsome mouth opens with a creak, exposing Star Phoenix's gaping maw to the opponent. Charging magical energy within his mouth, Phoenix unleashes a powerful attack known as Phoenix Blaze (フェニックス・ブレイズ, Fenikkusu Bureizu); an immensely powerful, explosively destructive blast of flame that is capable of traveling great distances, as seen when it was visible all throughout Crocus, wreaking havoc wherever it passed. The attack requires about 3 seconds to travel a few ten thousand-kilometer distance, and it possesses a penchant for widespread destruction, able to obliterate several buildings from a distance.
 * Phoenix Tail (フェニックス・テイル, Fenikkusu Teiru): The Drago Tail is a powerful special technique of Tsuruko's when harnessing Star Phoenix's power when acting as Gaiki; when utilizing it, she gathers magical energy within her lower back, which Star Phoenix then links to. Merging his own magical energy with the magical energy Tsuruko has gathered within her lower back, he then uses the dual energies to serve as a fulcrum—manifesting the tail of his true form, an avian tail outwards from Tsuruko's lower back. The tail is menacing; possessing an abundance of spikes around the tip of the tail, with jet-black scales which seem to glow red. Charging magical energy within the tail and transferring it outwards through the tip of the tail, Star Phoenix unleashes a powerful attack known as Phoenix Freeze Whip (フェニックス・ンフリーズ・ウィップ, Fenikkusu Furīzu Wippu), where Tsuruko first freezes the enemy (and whatever else nearby it) in place with her power, then rushes towards the frozen target with the Phoenix Tail, charged with raw elemental ice, and cleaves the foe with it.
 * Phoenix Wings (フェニックス・ウィング, Fenikkusu Uingu): The Phoenix Wings are a powerful special technique of Tsuruko's when harnessing Star Phoenix's power when acting as Gaiki; when utilizing them, she gathers magical energy within her upper back, which Star Phoenix then links to. Merging his own magical energy with the magical energy Tsuruko has gathered within her upper back, he then uses the dual energies to serve as a fulcrum—manifesting the wings of his true form, a pair of phoenix wings outwards from Tsuruko's upper back. These wings appear crimson in texture, with several black scales in place littered around the tips. By utilizing a variant of magical propulsion in conjunction with magical particles, she is capable of achieving extremely high speeds while leaving behind a trail of visible after-images to confuse her enemies. The speed and after-images granted by the Phoenix Wings allow Tsuruko to effectively dodge multi-directional attacks. Activating this attack causes a slip stream effect that allows Tsuruko to achieve speeds normally impossible to her in any location. By charging the particles with magical energy this allows Tsuruko an additional defensive measure as well as immense propulsion, allowing her to build up speed over time as she darts through the air.
 * Phoenix Hell Claws (フェニックス・ヘル・クロー, Fenikkusu Heru Kurō): The Phoenix Hell Claws are a powerful special technique of Tsuruko's when harnessing Star Phoenix's power when acting as Gaiki; when utilizing them, she gathers magical energy within her hands, which Star Phoenix then links to. Merging his own magical energy with the magical energy Tsuruko has gathered within her hands, he then uses the dual energies to serve as a fulcrum—manifesting the claws of his true form, a pair of phoenix claws outwards from Tsuruko's hands. These claws have a serrated appearance; similar to overly-long nails or the fangs of a dragon. They are reportedly extremely powerful; able to cleave through almost anything that Tsuruko can see, and deal astronomical damage to beings of demonic origin. When infusing the Phoenix Hell Claws with gravitational energy, Tsuruko can execute an attack called Phoenix Levitate Torn (フェニックス・浮揚・トーン, Fenikkusu Fuyō Tōn), where she infuses the Phoenix Hell Claws with gravitational energy before striking the enemy with a cross beam slash that delivers a tremendous amount of destruction to the surrounding area and the opponent.

Code DTD
"Restriction 666 released, Demon Host Detected, All Limiters Deactivated! Code: Dust to Dust, Activate! (第666拘束機関開放、魔主検、出全無効化、コード・ダスト・ト・ダスト、起動！, Dai roku roku roku kōsoku kikan kaihō, mashu kenshu, zenfū mukōka, Kōdo: Dasuto to Dasuto, kidō!)"

- Tsuruko activating Code: DTD

Code: DTD (覚醒態・奮闘力解 (コード・ＤＴＤ (ダスト・ト・ダスト), Kōdo: DTD (Dasuto to Dasuto) lit. Code: Dust to Dust, alternatively Awakening State: All-Out Power Released): Code: DTD, also known as Deus Machina Mode is the mysterious special function of Tsuruko's Deus Machina body—it is referred to her ultimate skill. It is normally activated through being triggered by a strong emotion; more often than not, either rage or sorrow. Once the emotional pull is achieved, Tsuruko's human "guise" is shed in place of her Deus Machina form. In her Deus Machina form, Tsuruko has luminescent blue eyes that make her appear quite akin to the ideal of beauty in the current age; though her hair remains the same. Any traces of humanity are not there in terms of her body, as she possesses a cybernetic body, including sprouting shoulder-pads, high-collared neck armour, ear-like protrusions on her head which are similar to boosters, armour covering her pelvic and the sides of her abdominal region, and similarly coloured armour on her thighs; however, she has golden lining at her shoulders, upper forearms, and thighs. Her most evident cybernetic portions are above her thighs, at her shoulder-blades, and supposed lack of feet; and what isn't cybernetic reveals that her bodily joints are like that of a doll's.

In any case, activating Code: DTD causes Tsuruko to enter a state of rage that drives her to destroy anything that threatens her, no matter what it takes; showing a drastically increased ruthlessness level that makes her a fearsome, unpredictable opponent—this is only enhanced by the fact that her Deus Machina mode leaves her pretty much on auto-pilot and will attack anything perceived as a threat with maximum force. However, the Code: DTD isn't evil, but it's not necessarily good either. Its main concerns are Tsuruko's survival, her rage and sorrow, and destroying "relics" from the Old World- indeed, Tsuruko's morals and innocent bystanders are secondary considerations, at best. Because of this, Tsuruko is somewhat afraid of this form, especially as it was the deciding factor in her deciding only to fight for the smiles of people after a certain incident in her childhood. The form heightens her concentration to the point that she blocks out all sounds except for her opponent's voice; and when in this form, her own voice becomes deeper and noticeably more menacing; indeed, its activation is usually accompanied by an excruciating amount of pain. Whenever Tsuruko becomes possessed by her Deus Machina form, it appears as if Tsuruko was somebody else entirely—or rather, in reality, she's controlled by her basic desires and her orders subconsciously installed within her frame by Dzerve Sejren.

It is a common misconception that when accessing Code: DTD, Tsuruko's abilities are greatly increased and she can move at greater speeds thanks to the exposed thrusters; while each of her blows can shatter the earth. When in Deus Machina Mode, Tsuruko can use her Zero Effect to take control of an enemy's magic and use it against the foe. Finally, DTD enables Tsuruko to use the in-built virus program created by Dzerve in order to quadruple her damage against those hosting demons, giving her a major advantage. DTD supposedly lets Tsuruko to control her body completely through her brain, thus it is breaking her limitations, essentially—her body will move like it would in a dream. The stress caused by moving in this manner, however, is way too much for Tsuruko—and ironically, that means that Code: DTD can only be activated for ten minutes before shutting down, leaving Tsuruko vulnerable. However, the truth behind the supposedly augmented abilities is that Tsuruko could perform all of those actions normally, and simply lacks the knowledge of how to do so or refuses to do so due to this form's increased aggression; this form simply brings them out for her to access automatically.

While initially uncontrollable, after resolving her personal issues and coming to terms with herself, Tsuruko was capable of fully mastering her Deus Machina Mode, entering a state of tranquility known as Clear and Serene (明鏡止水, Meikyō Shisui); which enables her to control the Zero Effect and her robotic instincts through sheer willpower alone; in order to harness the power of Clear and Serene, Tsuruko's mind must be clear, psychologically speaking; she has to free herself from all negativity in her mind and heart, and must maintain focus on the battle at hand and nothing else. Once she does this, she's capable of using her Deus Machina Mode at will. When under the effects of Clear and Serene, Tsuruko is able to overlay her Soul Armour with her Deus Machina Mode, enabling her to access her Super Mode without large amounts of Ardor gain unlike the other six prototype Soul Armours.
 * Zero Blades (ゼロ・ブレーズ, Zero Burēzu): The Zero Blades, noted by Gary as the "Dimension-Slaying Wings" (次元滅翼, Jigenmetsuyoku), are Tsuruko's main armament when the Code: DTD activates. They appear from her back the moment that Tsuruko becomes her Deus Machina Form. Something to note is that they're not technically wings, but rather solely blades that are coated with zero energy that eliminate everything around Tsuruko's body, even natural phenomena such as wind resistance, enabling her to soar higher with the rocket boosters installed within her feet. The blades appear similar to single-edged swords which are silver in texture, and have numerous runic markings engraved upon them. They move and take aim at the target according to Tsuruko's will, allowing her to fire without having to even touch them; they are shot with enough force to drill a hole through the prototype of Etherion, as shown during the Constellation Skirmish. While it is possible to block many of the strikes, to do so can be seen as suicidal. When Tsuruko goes all out, it is not uncommon to see a flurry of swords materializing out of thin air and disappearing just as quickly, flying and attacking rapidly from many angles at once; overall overwhelming the foe; or at least, placing tremendous pressure upon them, forcing them to keep their defenses up lest they be struck by a sword—causing dozens of other blades to perforate them in a matter of moments. The blades can be brought together to form a circular ring that is spun to fire a powerful purple laser of zero energy that is capable of splitting into many smaller beams; which is powerful enough to slice through metal with ease, and are seen to take down two attacking aircraft by cutting them apart. Indeed, Tsuruko is capable of conjuring mighty dragons born of blades to descend upon her opponents, or erecting nigh impenetrable barriers of blades which are stronger than the greatest binding spells. Upon firing them, Tsuruko can allow them to pierce the ground after striking the target, causing a large amount of destruction with each weapon, or she can instantly resummon the Zero Blades back to her vicinity. While it should be noted that the Zero Blades are more of a trademark of Tsuruko's Deus Machina Mode, she can harness them in her normal form or as Gaiki- though it takes quite a bit of willpower and focus in order to manifest them.
 * Spacetime Convergence Cannon (時空集中砲, Jikū Shūchū Hō): The Spacetime Convergence Cannon is the ultimate weapon of Tsuruko's Deus Machina functions; it was specifically installed within her frame by Dzerve in order to harness the full power of the Zero Effect by channeling it into a concentrated stream of energy that induces phase transition; which is the change from one physical state to another- in other words, it is similar to what happens when anti-matter comes into collision with its corresponding matter, resulting in the release of massive amounts of energy. The Spacetime Convergence Cannon is located within Tsuruko's abdomen—when activating it, her abdomen opens up, revealing an enormous cannon. Once activated, the zero particles are accelerated until they reach high speeds, carrying enough energy to vaporize anything it comes in contact with; no known defenses. Tsuruko's own Ardor fuels the attack, causing the zero particles to intensify by convergence and acceleration, before releasing it as an energy beam of immense power fired from the cannon, which, at full power, possesses enough force to turn an acre of desert into a sheet of molten glass. Against living beings, the Spacetime Convergence Cannon has enough firepower to vaporize almost anything outside of Soul Armour Knights in their Super Modes or Hyper Armourized Hellions. This cannon is among the most powerful weapons ever wielded, far outclassing even high-grade conventional weapons such as the complete Etherion and its successor, the Highlander. However, the Spacetime Convergence Cannon has a significant drawback; Tsuruko is required to anchor herself down onto the ground via foot locks or similar objects in order to successfully fire the weapon. This is due to immense kickback from firing the cannon, and without firm grounding, Tsuruko would either have her projection steered off target or even be thrown back.

Gary Straights
"Gary: Birdy, my mum mentioned that it doesn't matter even if you can't get 100 friends once you graduate to your next class, you must find a real friend that you can treasure with the feelings of 100 people. Once you get this true friend that you can view as more important than anyone else, your future will be bright. Tsuruko: Then, I'll use the feelings of a hundred people to treasure you. Even if there's 100 people... no. No matter if it's a million or trillion people, even if the entire world views you as an enemy, I'll still be your friend."

- Gary Straights and Tsuruko Sejren, in their childhood, Innocent Origins

Some of Tsuruko's most prominent interactions are with Gary Straights. The two used to be childhood friends and both considered each other best friends. In the present, their relationship is not good as it was in the past due to being separated for so long, but compared to other people that Tsuruko interacts with, she and Gary are very close; Giselle even notes that Tsuruko seems to be somewhat of a 'tsundere' towards Gary. After Tsuruko was forced to move away, she was traumatized by being separated from him; an event which triggered her desire to make friends with everyone, due to fear of losing a close friend once more. When the two eventually reunited, Tsuruko immediately recognized Gary as her childhood friend. However, to Tsuruko's dismay, Gary was unable to do the same, which is justified considering that Gary always thought of her as a boy and never really knew her true name in the past.

Gary deeply regrets that he couldn't say goodbye to "Birdy" and believes that this was the main reason why she ultimately became an outcast—often seeing dreams of his past friend, and trying to revise this past by using "time machine" that Alexis had invented; showing that the longing for each other is very much mutual. Even now, Tsuruko realizes that their past friendship is gone, and their relationship is that of two fellow students, not of childhood friends—much to her dismay. While appearing cold to Gary and only Gary, Tsuruko is continuously seen trying to make him remember their past. Whenever something romantic would happen between the two, both would blush and just brush it off; Tsuruko would sometimes remind Gary, but he just pretends to forget to avoid getting things awkward.

Interestingly, Tsuruko has some obvious affections for Gary, but due to shyness, inability to convey her feelings and pride, cannot say it out loud. The two possess a truly powerful bond; Gary and Tsuruko are frequently seen together, Tsuruko referring to Gary as the most important person to her—and the two possessing a bond that transcends any friendship or romantic relationship; being one of pure devotion. Gary would do anything for Tsuruko, and the feeling is mutual. However, their relationship slowly goes from affection to pure hate on Tsuruko's end as Gary left her all of a sudden.

However, during the Esper Excellen Part II arc, Gary finally revealed his true personality and reasons to her, and two decided to start off again as simply friends, not as the Gary of the past and "Birdy", but rather, as the current Gary and Tsuruko Sejren.

Excellen Kilekion
"Excellen: Haha, don't call me 'lady'. I'm more of a 'sir' than a 'lady' if you know what I mean. Well, what are you waiting for? Heya there, I'm Excellen Kilekion! All I know you as is All-Lovin' Girl from before—but I want to know you—not the idiot that embarrassed herself, the real you. Tsuruko: ...I'm Tsuruko Sejren. I-It's nice to meet you, Excellen...Kilizeon? Purugashion? Alphaeon? Sorry, your name is hard to pronounce... Excellen: Hahaha, don't worry about it! Just call me Cell, and I'll call you Sejjey. And! I'll be your friend here, you have my word!"

- Excellen Kilekion and Tsuruko Sejren, in their first meeting, La Pucelle

Upon her arrival at La Pucelle, Tsuruko was sorted into the Ōryu dorms, Excellen was the first to befriend her, stating that despite her lack of social skills, Excellen wanted to get to know the real Tsuruko, even coining the nickname "Sejjey" for Tsuruko. Even though the two are on different teams, Tsuruko and Excellen develop a close bond, as Tsuruko even lets Excellen carry her on her back whenever she offers to. As Excellen became more involved in Tsuruko's life, Excellen gave unyielding support to Tsuruko through everything, with or without Tsuruko's consent and/or knowledge.

Rosa Dimaggio
Rosa is Tsuruko's best friend and sidekick. The two have been together since Tsuruko joined La Pucelle Academy, in which the two first meet. They have been best friends for so long that they share a sisterly relationship. The two got off without any problems; as Rosa stepped in to defend Tsuruko from Kaguya Kobayashi when the snooty royal was berating her from the "grave" crime of bumping into her; Rosa indeed did send Kaguya packing with a harsh speech which utterly destroyed her self-esteem. The two quickly became close friends- deciding that they would partner up in teams throughout their stay at the academy. When Tsuruko decided to explore the area of the abandoned dormitory, Rosa witnessed her running at high speeds. Rosa was impressed by this and began to follow her. Tsuruko soon realized that she was following her, but allowed her to do so, since she was impressed by how Rosa could keep up.

When the symbiote Bahamut attacked the two for being near the secret of La Pucelle, Rosa proved to be a great assistance to Tsuruko, by backing her up in the ensuing battle, buffing her and healing her when the need arose. At the end of the battle, when Rosa saved Tsuruko from her fall from the building, Tsuruko had built a strong bond with Rosa, and the two became close friends. Rosa often invents machines for Tsuruko and also made her three upgrades for Dragredder. Giselle refers to the two as the "Unbreakable Bond" whenever they team up. While Tsuruko teaches Rosa how to run, Rosa mentors Tsuruko in the art of unarmed combat with her legs; which forms the basis of Tsuruko's fighting style. Whenever Tsuruko has an adventure to explore, she always comes to Rosa and asks her to come along, and Rosa is always ready to help.

Kaguya Kobayashi
Kaguya and Tsuruko's relationship and interactions get off to a bad start when Tsuruko knocks her over by accident when entering La Pucelle and nearly blows them both up. This small event solidifies Kaguya's opinion of her for the rest of S1; considering Tsuruko beneath her because of her background as a drifter/hobo, her childish behaviour, her lack of knowledge regarding magic-related terms, and her supposed 'rudeness' towards her which is simply Tsuruko being completely informal with her as she is with everyone else. When Tsuruko offers to try and make it up to her, Kaguya tells her she can start by leaving her alone. This continues late into S1 until Kaguya has to go see her parents, visibly worried about her lack of progress regarding her development until Tsuruko offers to accompany her after Excellen wouldn't give Kaguya the time of day.

When their train gets derailed, the two team up to fight off some criminals. At first, Kaguya doesn't think much of Tsuruko's abilities, seeing herself as vastly superior in combat; however, the moment that Tsuruko utilizes the Zero Effect to disintegrate an Altairis attack before using her super strength to fling the assailant into the distance surprises her greatly; though she still considers her to have a bad stance and their lack of communication and coordination drastically hampers their effectiveness. Even so, she later thanks Tsuruko for her assistance under her breath. Ironically, Kaguya became an ardent supporter of Tsuruko's alter ego as Gaiki after Tsuruko-as-Gaiki saved her, despite popular opinion against 'him'; even going as far as to make a Gaiki Fan Club; inviting everyone except Tsuruko to join and scared away reporters when they tried to interview people about their reasons for hating the Soul Armour Knight. It is hinted that Kaguya has a crush on Gaiki; despite her hatred of Soul Armours, she seems willing to put such a thing aside in this case. When Tsuruko tells her that she's Gaiki, Kaguya doesn't believe her; even when evidence for it constantly mounts up—to the point that when Tsuruko transforms next to her, she deliberately ignores it.

However, in all seriousness, as their arc together progresses, Kaguya finally gets to see for herself why a lot of people like Tsuruko when Tsuruko sticks up for her when her family begins berating her for not accomplishing more, and later when Tsuruko tanks an attack meant for her launched by Aquarius. Moved by Tsuruko's compassion, even when she'd treated her like crap, Kaguya quietly muses to herself that she'd begin treating her better from "now on". Their friendship is then finally solidified when Kaguya later admits to before how she knew it, she ended up in a "group of losers" and how she cannot escape what is known as a bond. She later ended up using her family's money to pay to build the Icarus Bridge that connects Four to Hargeon as Tsuruko and her old friends always wanted, sapping all of their wealth.

Deen Lhant
"Deen: "Well, you're free now." Tsuruko: Hey, Deen? Don't give up on your dream, okay? Maybe we'll cross paths again.""

- Tsuruko Sejren and Deen Lhant, in Paragon of Hope

While Tsuruko and Deen's relationship started off on a sour note, though only for the latter, Deen was shown to be touched by the former's kindness towards him, even though he had arrested her on the charges of being rather suspicious. As Tsuruko told Deen to not give up on his dream of being a superhero, the words struck him on a high note; as she gave him one of her Super Soul Rings and left. This caused him to become intrigued by her, seeing her as somebody other than any other mage—until he had met Tsuruko, the mages that Deen had encountered in his profession were cruel and arrogant, even those under Legal Guilds. His impression of her was further softened after he witnessed her petting a kitten on La Pucelle grounds. When his superiors instructed him to infiltrate La Pucelle, Deen immediately jumped at the chance—not for the higher pay, but for the chance to meet Tsuruko once more. After posing as a student and a later bodyguard for Team Daybreak, Tsuruko and Deen had become friends officially.

Deen is shown to be a bit of a tsundere towards Tsuruko, being somewhat harsh to her, but deep down, he cares; as he doesn't openly admit that he worries or cares about Tsuruko, usually feigning anger and yelling at her, which only makes Tsuruko smile because she can tell Deen's true feelings. In dire situations, Deen openly shows concerns and proclaimed he will do anything to protect Tsuruko from danger. It was shown many times that Deen holds romantic affection for Tsuruko; blushing when he is close to her or when she is being kind to him—because of this, he has a rivalry with Gary. While normally being cold, Deen will listen to Tsuruko's words and advice even when he is angry. However, Tsuruko's love turns out to be more of a platonic one- more like a sibling love than anything else- and since Deen himself is nearly a decade older than her, and Deen wasn't really interested in her in such a way.

Allies of Justice
The Allies of Justice (正義の味方「Ａ・Ｏ・Ｊ」, Seigi no Mikata) were a group of four exceptionally talented fighters whom all grew up in the Chateau des Tiffauges in Four. The quartet ran around the city, destroying what they perceived as oppression and a desire to pull off something big within the city of Four. Tsuruko was one of the founding members of the group, as Charlotte Merquise, her very first friend and only companion for the longest time, decided that they should do something about the polluted state of their home. While they managed to conquer Four, the team later disbanded due to Charlotte's questionable acts, as her personality soon began to change. This led up to an incident where Charlotte attempted to challenge the Magic Council, starting with causing an explosion inside their headquarters in Four, managing to mortally wound a Wizard Saint before Tsuruko came back and stopped her from finishing her enemy off. However, this ended in Charlotte seeing Tsuruko trying to convince the council to let her go, and she mistakenly believed that Tsuruko had her purposely arrested.

Charlotte Merquise
Charlotte was Tsuruko's very first friend- the two met at the Chateau des Tiffauges in Four; where Tsuruko was taken in by the "nice lady at the orphanage", whom found Tsuruko with her father's Driver Belt. In the orphanage, Charlotte stood up for her as some older children began to pick on her—the two teamed up to fight them off, with Tsuruko accidentally showing her super strength for the first time by crushing a bully's arm with a grab. After this, the two were placed in detention. During their short hour in detention, Charlotte and Tsuruko became fast friends, with Charlotte giving Tsuruko her nickname, and told her about her idol, "Phoenix Knight", a legendary superhero who saved those in need, inadvertently sparking Tsuruko's interest in superheroes; the two were told countless tales about the Phoenix Knight by the "nice lady at the orphanage" after she heard Charlotte mention her.

The two, along with Jack Titus and Carmine Fairchild, founded the gang known as the Allies of Justice, who went around defeating rival gangs and making things safe for civilians. Tsuruko had a higher respect and concern for Charlotte than Jack and Carmine as she was the only one who stayed when the Allies of Justice went their separate ways due to Charlotte's increasingly extreme behaviour, to the point that she tried to give herelf up to the Magic Council in order to save Charlotte from punishment, even if it went horribly wrong. Even after Charlotte returned later on with a major chip on her shoulder against Tsuruko and attempted to take Tsuruko's life, she continued to try to save Charlotte. Amusingly, it's revealed during the Esper Excellen two-parter that Charlotte was the one who taught Tsuruko how to haggle regarding food.

Gaiki
Tsuruko's relationship with Gaiki is a special one. Although Gaiki is just a armour to many people, Tsuruko has always referred to the armour as its own sentient being; always counting on it to support her throughout her battles, referring to Gaiki as part of herself. Moreso, it can be said that Gaiki is the living embodiment of Tsuruko's dreams to be a superhero, or rather, to become somebody as loved and heroic as 'Phoenix Knight', rather than a Soul Armour proper. She refers to Gaiki as her "avatar" in battle. It is implied, and later outright stated, that Tsuruko has an empathetic connection with her Soul Armour because of her strong bond with it and her constant belief that Gaiki is sentient, making Gaiki much stronger than other Soul Armours.

When Gaiki, along with the other Soul Armours, was sealed away in Daybreak S3, Tsuruko's immediate priorities were to get it back, going through numerous trials in the process. When it is revealed that the Prototype Soul Armours are indeed sentient, Gaiki is the very first to show sentience, finally confirming for Tsuruko that they have always been fighting together as it told her that they've always been 'one and the same'. In fact, Gaiki was what saved Tsuruko from a nasty fall after she and Alphonse were knocked off a cliff in the past- as it manifested for her for the first time to cushion their impact; and it has saved her numerous times, whether Tsuruko was aware of it or not.

Developer's Notes
Brooding. Stoic. Cold as ice yet hiding a lot of insecurities underneath that stoic appearance.

Those words sum up Jason LaHote quite nicely; at least until the time-skip in the story.

However, Tsuruko is designed to be his polar opposite. I wanted to make a character so different than the protagonist of Dawn so that readers wouldn't feel as if they're reading the same story with the main character possessing a different name. It's been my goal for a while to make a main character that wouldn't be relegated to the background (as in, not rather important in the grand scheme of things) in Dawn; and I do say that I succeeded. While Tsuruko doesn't show interest in Jason, she has her own love interests and personal life which nobody in the main story affects or distorts in any way.

Tsuruko hasn't had much character development because I fear that if I change her personality even slightly, it'll ruin my view of the character who's meant to be a shining hope for the world; though on the whole her character has remained the most consistent with what I was originally trying to portray—a kind, selfless soul. So, while Tsuruko doesn't get lots of characterization, she spends time giving character development to everyone else; however, like everyone else in Daybreak, she is a highly fleshed out and engaging character.

In terms of powers, I derived Tsuruko's skillset off what would be Jason's polar opposite at first; using kicks to balance Jason's punches, and more varied magic; while Jason is mostly focused on beams of energy, swords, and power-ups, Tsuruko is highly varied with her Super Soul Rings. This manifests in their sword-fighting styles; with Jason using sharp and powerful, precise movements, while Tsuruko fights in a flashier, more fluid way and uses her agility, creativity and sheer impressiveness; yet she isn't as physically powerful as Jason.

What's prominent is that Tsuruko has a sun theme; which relates highly to her personality. The sun provides warmth for all of us, but on a bad day, it will be unbearably hot and melt damn near everything. The same goes for Tsuruko; she's kind to everyone he meets, but piss her off and she'll snap!

Anyway, I hope you all like Tsuruko as much as I do.

Trivia

 * Tsuruko is the author's main character for the Sun Trilogy; having finally decided on a main character she would never discard.
 * Via Word of God, Tsuruko is her favourite protagonist in the Sun Trilogy; because of the general everyday setting of Daybreak, she feels more attached to Tsuruko, and considers her somewhat like a friend or a senior. In contrast, Giselle is more of someone you would admire as a hero.
 * Tsuruko is the second main character of the author's whose theme revolves around phoenixes.
 * Interestingly, Tsuruko's favourite food seems to be chili dogs.
 * Tsuruko's name can also derive from 釣瓶落とし; tsurubeotoshi, which is to sink quickly, referring to her habit of conforming under pressure and send conversations she is spiraling into awkwardness.
 * Tsuruko's battle theme in Daybreak is called Clear and Serene; however, her appearance in Dawn's final arc is heralded by the music known as These Hands of Mine Shine with a Roar. In addition, Tsuruko's battle theme as Gaiki (aka, from Showtime onward) is Strike Shutsugeki.
