Rosa Dimaggio

Rosa DiMaggio (ローザ・ディマジオ, Rōza Dimajio) is a student of La Pucelle Academy; and Tsuruko Sejren's partner as well as her eccentric roommate. However, there is much more to this young woman than meets the eye. She is a mysterious young girl who is the very first person to greet Tsuruko at La Pucelle Academy. Despite facing many hardships, carrying a dark past and a heavy burden, Rosa remains a caring and upbeat person. Initially unknown to her friends, Rosa's actions have a large impact on their lives and those of the people around her. Rosa is a Cyborg (サイボー, Saibōgu); a mage who has been upgraded cybernetically as she had lost most of her body in an explosion.

In reality, Rosa is the Berserk Steel Dragon, Indra (荒れ鉄竜・インドラ, Areganeryū Indora); whose sole mission is that to slay the Tyrant Dragon Vritra.

Appearance
Rosa appears as a teenage girl; she is able to maintain a trim, young-and-beautiful appearance, despite her heritage. She usually has a kind, soft expression on her face. She has large, D-cupped breasts, wide and womanly hips, a shapely rear, a thin waist, long, beautiful legs, and a perfect physique. Possessing blonde hair, her hair flows loose and messy, with a few tendrils sticking out and a small cowlick on top of her head. She has a pale complexion and emerald eyes. Normally, she will wear casual attire, but when she heads into battle, her clothes completely change. As a cyborg, Rosa's right arm and everything from the hips down were transformed into machinery.

Her battle attire is a mixture of yellow, brown, orange, and black. She wears a tan vest with gold piping over a yellow, cleavage-and-midriff baring shirt with a black crest that resembles a small body of fire. The vest has puffy cap sleeves with black cuffs. On the sides of the cuffs, there are two small golden buttons. She wears a brown belt with a buckle, a pouch, and a small banner-seeming object. The same black crest appears on this banner, only golden in color. She wears black shorts under her belt, which in the back, resembles a pleated skirt. Over the shorts but under the belt is a white, asymmetrical back skirt. She wears an orange circle scarf (with no apparent edges) around her neck, but no other discernible jewelry. She wears brown, mid-calf platform boots that look like leather, with orange socks of different lengths. The right leg also has a grey bandanna-like object wrapped around the top of her left boot. She also wears finger-less black gloves.

Personality and Traits
Sweet, beautiful, gentle and maternal, Rosa always looks for the brighter side of life and tries not to let the little things get to her. She's an optimist by nature and has a soft feminine charm and speaks in a heavy southern accent. She's somewhat pragmatic and down to earth, though she's also a good-natured flirt. Despite her girly ways, she has a tomboyish streak in her, especially when it comes to her love of sports; martial arts in particular. Rosa has a childlike innocence, and is considerate, understanding, upbeat, and at times, headstrong and stubborn. Rosa is empathetic, easily driven to tears, and cares deeply for other people, Tsuruko in particular; she remains positive in situations others deem hopeless. She tries to learn as much as possible, and has developed a habit of collecting information on anything new.

The urge to know sometimes drives her into doing odd things, or making others do odd things for her; she even carries a small handbook around to write down everything she ever recorded. She has a very cheerful and loud exterior, which exasperates others at times. She is also very friendly and eager-to-please, but tends to rush recklessly into things and is quite clumsy. She's no pushover from either a physical or a mental standpoint, having a strong sense of courage and determination, and she enjoys competition, though she's never a sore loser. She holds deep love for her friends and family and while she's not afraid to speak her mind, she has their best interests in mind and is always willing to offer her support.

Although she usually has good intentions, Rosa tends to cause problems or make things worse. Though she possesses similar qualities and ideas to Tsuruko, such as helping others when needed, she is a daring person who will rise up to any challenge and show that she is not a pushover. She is also generous and altruistic, as she is willing to fight for the sake of her friends and for those she considers her family, including underprivileged children that she helped raise. Though occasionally portrayed as comic relief, she is essential to the plot and the series' overall theme. She is an enthusiastic warrior, who claims using magic is about fighting to help people you love.

Rosa has a strong admiration, and an albeit fan-girlish personality towards Tsuruko, since she knew that Tsuruko is the last member of the Sejren Clan, and even refers to Tsuruko as the "crown jewel" of Earth Land. Rosa treats Tsuruko with the utmost respect and is eager to do things for Tsuruko that will please her, such for Tsuruko as new class representative of their class. She tries to cheer up her friends when they're down, and see the bright side of things, but her bubbly personality is a façade to hide her fear and guilt. Despite this, she is very suspicious and stubborn, and has a fear of clowns due to an incident on her fifth birthday. Since being upgraded to a cyborg, Rosa has had mixed feelings about the experience. Though she has struggled with being a cyborg, she appreciated the abilities her mechanical limbs provided and their usefulness in battle.

History
Interestingly, Rosa is no mere high school student. Four hundred years ago, Rosa was a resident of Hargeon; and during the Human-Dragon War, she lost her family at the hands of the Everlasting Darkness Dragon; after meeting at an orphanage, Rosa and a young man known as Tenchi Sejren became friends; and Tenchi decided to become a dragon to protect Rosa and their home and Rosa tagged along. By being imbued with the power of dragons, Rosa and Tenchi were granted the power of Ragnarok and given mission to destroy the Source of Magic.

In the war's climax, Rosa was too scared to use the power of Ragnarok, so Tenchi became the Tyrant Dragon Vritra alone, but only scarred the shell of the Source of Magic. Taking pity on the people of Earth Land, the Exalted One intervened and crystallized Rosa and Tenchi before they could finish the job. The crystallized forms of Rosa and Tenchi were placed within the Vestige, which was taken into the Source of Magic in the war's aftermath.

Four hundred years later, Rosa and Tenchi awaken from crystal stasis. Rosa has lost the memory of their previous goal and her own dragon form; to keep more people from getting hurt, Tenchi pretends he has as well, then later takes on the burden of transforming fully into Vritra to spare his old friend the guilt and pain. Although Tenchi's dragon power is scorched and unchanging, Rosa's dragon power is still active. Tenchi is unwilling to stand by and watch Rosa become the Berserk Steel Dragon, and vows to complete their mission; wiping her memory as he used Compact Regression upon her, Tyrant Dragon Vritra takes up an entirely new identity, to change the world for Rosa's sake.

Rosa herself was left wandering the lands, in search of the answers to her past. However, upon meeting Raike Sejren, she suddenly realized who she was—and what her old friend has come to, all in the pursuit of fulfilling a promise. Determined to stop him, Rosa fabricated an entirely new personality—that of a clumsy and ditzy teenage girl, in order to find Vritra and end him by her own hands; to save him from falling further into darkness. Some time during her travels, Rosa was heavily injured; and as a result, her right arm and everything from the hips down was converted into metal—making her a cyborg. Despite this loss, it did not affect Rosa too much—seeing her new status as a blessing, as she could use the new limbs in order to find Vritra easier.

Equipment
Vort Grenade (ボルトグレネード, Boruto Gurenēdo): Vort Grenade is the name of Rosa's greaves; they are classified as "Supreme Velocity Flame Shoes". Vort Grenade's design are mainly white, with black heels and soles, and what seems to be a red strip of metal lines the bottom of each greave—along the sides of the greaves are numerous gems encrusted within the stainless steel of Vort Grenade. The strip at the bottom of each greave has a spot where the red has been scratched off, as a sort of "battle scar". The bottom of each greave is black, and has a pattern of small "jets" which Rosa uses to propel herself forward. The shells initially wrapped around it are red and orange. Each magazine consists of 12 shells, giving 24 shots in total when both greaves are fully loaded. Whenever Rosa is running, her movement creates the illusion that she is skating. This is because the jets on the soles of Vort Grenade propel her forward at a constant pace, but she moves as if she is simply skating along the ground; thus drastically increasing her speed. Vort Grenade is made of a devilish metal which absorbs organic material and transforms it to steel, and its techniques can be powered up by engaging the thrusters on the greaves. The greaves have small drills on each toes capable of extending during some attacks, as well as small saws allowing Rosa to cut through enemies with kicks. Additionally, Vort Grenade's offensive function seem to be rooted in creating pulses of raw kinetic energy; which is released from the jets on the soles of the greaves. They emit flashes of light resembling explosions or flames whenever Rosa kicks towards her opponent, and are capable of knocking enemies back great distances. However no solid projectiles are ever fired as evidenced by enemies being knocked back, but lacking exit or entrance wounds that would be characteristic of being shot with a solid object.

Ways of Combat
Master Hand-to-Hand Combatant: Rosa fights primarily with kicks, focusing on a form of kickboxing, a style she has derived from her special combat training, and is rarely seen using her arms or fists when fighting, very much like Tsuruko, whom she mentored in the art of fighting. When in battle, she primarily fights her opponents by using a large number of skillful and specialized kicks to strike blows. Using her agility in line with her training, Rosa can perform moves such as high kicks, side kicks, spinning kicks etc. striking her opponents with deadly precision and efficiency, and can even send her whole body spinning through the air with her feet first, turning herself into an all-piercing spear. Her fighting style frees the use of her hands and prevents her from being damaged during a battle, something that is disastrous to her. As a result; Rosa tends to drop into certain stances in which her upper-body portions are most relaxed, such as placing her hands inside their pockets or crossing her arms together across her chest, and only puts them into action whenever the event requires her to do certain maneuvers such as handstands, which aren't prohibited. Rosa boasts a wide and impressive array of kicks, coupled with super acrobatic skills, her fighting style allows Rosa to effectively weave continuous and powerful attacks upon adversaries She can even deflect and parry magical blasts with her kicks, at both close range and long range. Rosa can also complement her fighting style with her flight abilities, allowing her to take her fighting techniques to airborne opponents and allowing her to launch aerial kicks and strikes at her opponents. Rosa's strength originates from her Iron Dragon Slayer Magic and relies heavily on their execution. By using her magic in conjuring with her moves, Rosa can create unique and dynamic attacks that deal destructive damage on her targets, making her a fierce force to be reckoned with in combat. To boost her offensive power, Vort Grenade has barrels implanted inside the jets that use bullets, and, when triggered, cause flames to erupt from the greaves to deal more damage. Her kicks can shoot explosive rounds towards enemies at a distance, or create explosions in her foes' faces.
 * Hyakueretsukyaku (百裂脚, Hundred Rending Kick): Rosa's signature technique; when using the Hyakuretsukyaku, she stands on one leg and kicks rapidly, or "at the speed of lightning", with her other leg extended out. The kicks come out with incredible speed and power, and can land several hits. These several hits can add up to an impressive amount of damage when not blocked, and does a small amount of chip damage even when blocked. The kicks impact at incredible speeds, striking like a meteor shower, attacking relentlessly and assaulting everything in her wake; Rosa has shown that she is able to kick for sixteen seconds straight before having to take a breather. If most of the hits connect unblocked, they could quite possibly dizzy the opponent. However, above all, Hyakuretsukyaku is deadliest when used against a cornered foe, due to the limited amount of space to escape it, even when blocked.
 * Rider Kick (ライダーキック, Raidā Kikku): Rosa's ultimate technique; when performing the Rider Kick, she utilizes Vort Grenade to accelerate her movements to tremendous speeds—so fast that the opponent cannot see where she is moving—then, by jumping forward, she unleashes a powerful flying side kick that attacks the opponent head-on—slamming down upon the opponent with her feet with a strike that equals over 300 tons in weight, more than enough to completely shatter the opponent into innumerable fragments. The only major weakness of this technique is that Rosa has to focus all her power into her legs, forcing her to lower her arms and enter a guardless stance; which can allow the opponent to strike; as she focuses all of her power while maintaining her center of balance and delivers a kick at the opponent's weak spot; shattering any defenses and severely winding them.

Robotic Armaments: As a cyborg, Rosa has a huge array of extremely destructive weapons concealed in her arms, including two rapid-fire machine guns, two flamethrowers, two missile launchers, two unconventional rocket-propelled exploding drills that function similar to missiles and energy cannons. She can also rapidly rotate her hands and lock-on to a number of surrounding enemies, then release to attack with a laser. She as eight single-barrel weapons deployed around her wrists are seen that fire a spray of pellets that can blow away anything in close range. However, she's shown to be able to hit foes with them well outside of effective range. She is also armed with explosive rounds for her machine guns, as evidenced by the damage she caused to the base she was sealed in by only firing for a few seconds. Even with all these weapons, Rosa is rather inaccurate; despite the fact that she has some form of targeting system, most notably when she is firing many shots in every direction with expectations that some of them will hit. She only uses it for certain weapons, but why she wouldn't use it for all her armaments is unknown. Lastly, she displays built-in arm weapons that can fold out eight semi-automatic guns all around her wrists instead of just replacing her hands with them; and she was also able to replace her hands with two powerful black Miniguns. Rosa is described as a "walking arsenal" due to being equipped with a considerable amount of weaponry, giving her "more firepower than several demon hordes combined," according to an onlooker. Furthermore, she is apparently capable of carrying roughly half the firepower of all of the Magic Council.
 * Z-Buster (ゼットバスター, Zetto Basutā): The Z-Buster is a personalized arm cannon that Rosa 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 Z-Buster from pure willpower and energy. Rosa 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 Z-Buster 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 Rosa 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. What is interesting to note is that her buster system is potentially extremely powerful in the fact that its charging capabilities are theoretically infinite. Interestingly, she may also have a faulty or nonexistent targeting system, explaining her reliance on spread-fire weapons and explosives; not even appearing to be trying to aim.

Physical Prowess
High Strength: With the power of her kicks, Rosa could easily break through rock and leave footprints on iron. Against numerous foes, the wind alone from one of her kicks was great enough to strike a number of cannonballs in mid-air, and cause them to lose their fire and fall to the ground, motionless. Although Rosa is primarily known for her incredible leg strength, the rest of her body is shown to be just as superhumanly strong and durable, including her arms, which enables her to use an array of handstands, for her fighting style, which makes her much more versatile in certain combat situations. In fact, she is so powerful, that she is capable of splitting the hydrogen in the air just by merely punching, allowing her to cause a small explosion that inflicts decent damage. Another feat of strength is that she can punch the ground with enough force to cause small fissures. Rosa is able to lift and press 75 metric tons, and she can perform other amazing feats such as punching holes right through thick steel, shatter boulders to smithereens and lift objects many times her own size and weight with her non-mechanical hand; a shocking display of fearsome power in itself. Her strength allows Rosa to create thin shockwaves of air that cleanly cut through anything they come in contact with. Furthermore; she shows the ability to pulverize large boulders and the like with a single strike using her finger, while others marvel at the level of strength she possesses. Rosa is able to break the neck of a demon with only a kick, critically damaging it, and not showing any trouble afterwards; as well as shatter an Ice-Make construct with a sweeping kick. Due to being part-cyborg, Rosa possesses tremendous strength in her mechanical limbs and can extend them several times their length to improve her reach.

Immense Speed: Rosa is also quite agile, and quick on her feet, swiftly blocking and dodging attacks while moving from place to place without lag, being able to do fast shifting and evasive flips to move around in combat. With Vort Grenade, Rosa can hover-skate at supersonic speeds, even nearing that of hypersonic speeds, and is fast enough to nearly equal the speeds that Tsuruko can run at, making her one of the fastest characters in the series. She can also use the momentum from Vort Grenade's shots to propel herself in battle as well as spin herself around extremely quickly, much like how Tsuruko fights with Dragredder. She is extremely agile as well; able to jump to great heights or even balance herself on a flying rocket, as well as run up vertical walls. In addition, her agility allows her to perform amazing feats of acrobatics that easily surpasses even the finest human acrobat. She can also instantaneously close long distances without being detected by others. Lastly, Rosa's sprinting abilities have reached a point where she can momentarily run under water; not only is she not slowed down by the weight of water, but she can run to a degree of incredible speed as fast as a leviathan, with her speed underwater on par with a leviathan while under water. She has rocket boosters in her feet for flight; something that enhances the speed of Vort Grenade even more.

High Durability: Due to her cybernetic nature, Rosa has demonstrated extreme durability, being sent crashing through a wall and landing without a flinch or a minor injury, suffering no damage at all from some of Gary Straights' attacks, and emerging unharmed from most of E's attacks during their battle, 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 Lacrima with her fist without showing any sign of pain or injury. It is also worth noting that, for nearly all the battles Rosa has endured, she has never been crippled, nor has she displayed any serious injuries. Additionally, Rosa appears to be very durable, as shown by how she has a very high defense and survived in Bevelle while in shutdown mode for many years. However, her cybernetic nature is also a liability. Magnets could be used to restrain her and EMP (electromagnetic pulse) blasts could disable her limbs, which would render her helpless; furthermore, she's been susceptible to forces that can take control of technology, such as nanites. Due to being only half-Cyborg, her robotic limbs lack an actual battery; as such, overuse of her more powerful abilities, such as her laser cannon and shield generator, could greatly tire her out, and extreme overexertion has the potential to kill her.

Magical Abilities
High Magical Power: Thanks to her heritage, Rosa is in possession of an absolutely overwhelming amount of magical power. Rosa has natural control over the exertion of her magical power, keeping it contained to the point where it is virtually impossible to detect her by normal means, though the constant effort can be taxing. The presence it exudes is completely at odds with her personality; the magical energy itself is a vibrant golden, crackling intensely when Rosa focuses.

Iron Dragon Slayer Magic
Iron Dragon Slayer Magic (鉄の滅竜魔法, Tetsu no Metsuryū Mahō): Iron Dragon Slayer Magic is a Caster Magic, Lost Magic and a type of Dragon Slayer Magic that utilizes iron. Despite being Indra, Rosa is unable to utilize Iron Dragon Magic proper, because she had never fully transformed into the Berserk Steel Dragon. Due to the destiny not being played out, the Iron Dragon Magic was downgraded into Iron Dragon Slayer Magic—however, despite the downgrade, Rosa is said to be the strongest Iron Dragon to ever exist. Iron Dragon Slayer Magic is a form of Dragon Slayer Magic which allows Rosa to incorporate the element of metal—specifically Orichalcum (オリハルコン, Oriharukon); the ally of the first ages which is said to be absolutely indestructible. It is an intermediate material between the alloy and living tissue, so it is able to integrate with living tissue, and it possesses both the super-hard firmness of the alloy, as well as the smoothness of living tissue; it's absolute hardness is impossible to measure. Despite being a metal, it is flexible enough to be used for constructing wings and weapons; these structures will be infinitely more tough than if they were made out of any other material; the material itself is a shining gold and renders Rosa completely invulnerable, allowing her to attain high defensive and offensive power without losing speed.

In addition to this type of metal, Rosa can integrate, any other type of metal in existence into her body by existence, granting her the ability to change parts of her body, or the entirety of it, into metal, which can be shaped in a number of forms for different purposes, and to produce iron objects. When using this magic, she is almost unable to be harmed; and its absolute hardness is impossible to measure with this magic active, Rosa's body possesses super-hard firmness of this metal, as well as the smoothness of living tissue. When utilizing Iron Dragon Slayer Magic, Rosa keeps mobile and only roots herself when it is time to attack, and even then only long enough to actually launch and direct her attacks. The Magic relies around the use of Orichalcum for both offense and defense, with Rosa being capable of creating a wide array of weapons from her body to attack the opponents both in melee and from a distance; and to cover her body with the metal in order to drastically increase her defensive power, whilst simultaneously heavily boosting her offensive power. Despite the impossibility, the Orichalcum produced by Iron Dragon Slayer Magic is even stronger and more durable than any other metal, and it is capable of rendering some physical assaults useless as it enables her transform parts and most likely all of her body, into this metal. Rosa is also able to manipulate existing shards of metal, making them form an offensive spray of tiny shrapnel, and a thick shield made entirely of metal which can only be seen through from within.

Iron Dragon Slayer Magic gives Rosa the ability to greatly increase her offensive and defensive capabilities, as her already strong physical attacks are enhanced by the density of her Orichalcum body. Her defenses seem to enhance exponentially, and she is able to block the strongest slash in the world from the world's greatest swordsman, Gary Straights, with no visible damage to herself. Rosa incorporates the metals she manifests into her fighting style, greatly increasing the damage of her blows; additionally, due to being the ultimate Iron Dragon Magic, Rosa can take control of any type of metal—even that of the metals of weapons, and erode them or consume them, meaning that almost any type of weapon is worthless against her might. Additionally, Orichalcum is partly composed of a explosive reactive substance; so, with every attack that Rosa makes, the impact from her attacks will cause a small explosion—this explosion is not extremely powerful unlike others, however, it has more than enough force to launch the target backward after being struck, with enough destructive force to form a crater in the wake of the attack. Lastly, being a form of Dragon Slayer Magic, this also allows Rosa to consume external sources of metals to replenish her strength and restore her body to a healthy state, though, like any Dragon Slayer Magic, she is unable to ingest metals that she herself created.


 * Iron Dragon's Roar (鉄竜の咆哮, Tetsuryū no Hōkō): Iron Dragon's Roar is a Iron Dragon Slayer Magic Spell, it is the Iron Dragon Slayer's exclusive Dragon's Roar, incorporating the element of Orichalcum. Rosa first inhales, gathering the precious metal within her mouth; adding her own magical power into the mixture to serve as a propellant to the metal; charging it up for a few moments. Once the charging phase has been completed, Rosa unleashes a mighty roar which she quickly shapes into the form of a tornado that is shot towards her foes. The tornado itself is shot like a bullet—being evenly sized, while possessing tremendous blunt force as it barges into the opponent, blasting them away. Such tornado possesses immense force, being capable of generating powerful explosions and inflicting heavy blunt damage, but also releases sharp shards of the precious metal in the process, to shred the opponents' body. The Orichalcum released alongside the hurricane are able to pierce powerful strong magical barriers in the process of movement, thus even a barrier erected by Vritra would also be sundered; the Orichalcum fired work similar to a shotgun; spreading the damage dealt by the attack over a greater area. It is stunningly more powerful than a more focused blast due to the wider focus of the blast causing more widespread damage, rather than the narrower, more penetrative beam of regular 'Roar' techniques, already more than powerful enough to penetrate magical barriers. Due to the explosive reactive properties of the precious metal, each shard of the roar generates a powerful, burning explosion that bolsters the damage tenfold as the opponent is bombarded by blast after blast. Lastly, Iron Dragon's Roar is capable of generating an immensely powerful, explosively destructive blast that is capable of traveling great distances, as seen when it was visible all throughout Crocus, wreaking havoc wherever it passed.
 * Iron Dragon's Scales (鉄龍の鱗, Tetsuryū no Uroko): A powerful defensive spell; when utilizing Iron Dragon's Scales, Rosa covers part of her body, or the entirety of it in scales of Orichalcum, dramatically increasing her offensive and defensive abilities. When punching and kicking while covered in these scales, Rosa is capable of creating powerful gusts of wind through mere kinetic force; massively bolstering her power in close-combat. These scales are strong enough to withstand even some high-tier spells, making Rosa function as a makeshift battering ram or cannonball. With this, she is even able to stopping a downward slash from E's Caladbolg; and they are strong enough to shatter bone and rock alike, are resilient against almost every single type of spell in existence. When Iron Dragon's Scales is active, Rosa has the ability to manipulate the atomic structure of her physiology at will, allowing her to form her limbs into Orichalcum weapons more freely, however she can control all metals, regardless of it being part of her biological structure or not. Iron Dragon's Scales is great for defense, especially against fire. With Iron Dragon's Scales active, Rosa shines gold because her whole body is clad in Orichalcum; as her build is becoming crisp and sharp; the metal emits high-class golden radiance simply due to its dazzle. As her defensive power is immense and lightweight, Rosa's movements are surprisingly more agile than she appears from her new heavy armour. Because of the glittering and sharpness of her body, her enemies only see Rosa's figure as an afterimage that cannot be pursued.
 * Iron Dragon's Crushing Kick (鉄竜の砕蹴り, Tetsuryū no Saikeri): Rosa's signature spell; when performing Iron Dragon's Crushing Kick; Rosa covers her leg in Orichalcum—before swiftly turning away from the opponent and bending down, before throwing a fast back kick into the opponent's torso. This initial strike has Rosa spinning around as she delivers the kick; which works similar to a vacuum; if the foe is caught by the initial blow; then they will be struck the successive eight times. It is one of Rosa's most powerful blows; mostly because of it's "multi-hit" feature which doubles the damage as the explosive reactive substance within Orichalcum reveals itself; transforming into flames that spread out onto the opponent, swirling around them in a powerful spiral, creating a grinding drill effect that blasts into the opponent, inflicting major damage and launching them far away, creating an impact which is powerful enough to propel the unlucky recipient several meters away. The incredible speed both makes the strike far more powerful, and harder to dodge. The amount of time in which these actions transpire make it seem as if the opponent has been kicked with the force of a powerful cannon shell, blowing them away instantly. Despite its basicness, Rosa prefers to use Iron Dragon's Crushing Kick to finish opponents, as it is a stylish and graceful way to win the battles, and has different powerful variants as a result. Iron Dragon's Crushing Kick also covers a lot of horizontal distance, allowing her to strike an airborne opponent from several meters away.
 * Iron Dragon's Sword (鉄竜剣, Tetsuryūken): Iron Dragon's Sword is an Iron Dragon Slayer Magic Spell. In order to perform this spell, Rosa manifests a large amount of Orichalcum on one of her arms or legs; before focusing it and shaping into a large, jagged blade composed of the precious metal which possesses incredible cutting power—making it all the more deadly. The spikes along the blade's edge make its slashes more painful and dangerous, and the sword's length can be increased to reach enemies who are far away from Rosa. It should be noted that from this singular sword, she can generate a plethora of other, smaller swords, which increase her range even further. It's power and reach allows her to slice may objects, including humans (at its strongest without any reinforcement), clean in two, and if she expels more of her magical aura into it, it can cleave through even the strongest of magical barriers, while causing a 'backlash' effect which enables her to harm a foe by releasing the blade in the form of a blast of pure energy at them the moment she shatters a barrier. The blade is also sturdy enough to function as a shield of sorts; and the sword can also function as a chainsaw, effectively increasing its potential damage output while its explosive reactive properties bolster the damage dealt even more. Normally, Rosa will utilize Iron Dragon's Sword by manifesting it upon one of her feet, and performing a handstand while spinning around, carving up the surroundings.
 * Dragon Slayer's Secret Art: Black Steel: Super Powered Tyrant Breaker (滅竜奥義・黒鉄・超力鳴動破, Metsuryū Ōgi Kurogane Chōrikihaōha): The strongest Iron Dragon Slayer Magic spell that Rosa possesses; it is one of her Dragon Slayer's Secret Arts, the strongest techniques of a Dragon Slayer—this spell in particular was created for the sole purpose of slaying Tyrant Dragon Vritra, which is indicated by the name. In order to cast Black Steel: Super Powered Tyrant Breaker, she gathers magical energy within her body and condenses it; as she activates her cyborg functions; unleashing her true might, showing her full arsenal. Her arsenal includes two rapid-fire machine guns, two flamethrowers, two missile launchers, two unconventional rocket-propelled exploding drills that function similar to missiles and energy cannons—a fearsome display, indeed. At a single thought, Rosa unleashes a beautiful geometric curtain of death; an en masse firing solution. However despite its power, this attack can only fire in a forward direction. At any time, Rosa can initiate this attack without any preparation after simply targeting the enemy with her pointer finger. She can fire beams of energy without pause, and the result is something that resembles a bombing raid that leaves the ground scorching red. The energy beams released by this spell contain incredible power—a single one of them is capable of tearing through defenses and destroying weak foes with a singular strike; essentially becoming an overwhelming stream of absolute destruction, spreading out for miles, ensuring that nothing is left standing.

Trivia

 * In post-Vedic myth, Vritra, an asura, stole all the water in the world and Indra drank much Soma to prepare himself for the battle with the huge serpent. He passed through Vritra's ninety-nine fortresses, slew the monster and brought water back to Earth. This neatly mirrors E and Rosa's relationship; as the Berserk Steel Dragon Indra is the only thing that can permanently kill the Tyrant Dragon Vritra.
