Tsukiko Kriya

Tsukiko (月湖, Tsukiko) is a S-Class Mage from the Shadow Knights Guild, an Old Generation  Dragon Slayer, Eagle Dragoon's finance, and a former. Tsukiko is also a former member of A Thorn Between Two Roses. She is one of the main supporting characters of Fairy Tail: The Dragon Slayers, and is a close ally to the Fairy Tail Guild. Tsukiko learned her Dragon Slayer abilities from Shade, her Dragon foster mother.

Appearance
Tsukiko is a young woman of average height with a curvaceous body. She is recognized for being incredibly beautiful. She has bright red cat-like eyes and long silver flowing hair. She wears what appears to be a common school uniform with a green suit jacket, a white blouse with the top un-buttoned and a light brown colored patterned skirt. She also wears a typical school's dress shoes and black knee socks to match. She is also seen to wear a roasary around her neck, but at several times is seen without it. Because she is a Dragon Slayer, and like all Dragon Slayers, Tsukiko has elongated canine teeth.

Later on, Tsukiko wears a steel armor and pauldron like coverings. The armor like coverings clad her legs to just above her knees like long leg boots, and the arms are also clad in long sleeve like armor with shoulder pauldrons.

Whenever she goes to formal events, she wears a long white dress or black dress with strange designs around it. She also wears high heels.

Personality
At first, Tsukiko was rather cold and reserved. She also acted highly aristocratic and arrogant, looking down upon any enemy who was weaker than her, due to their audacity to challenge her. She would also boast about her abilities, believing herself to be stronger than most mages, and would even laugh at their vain attempts in launching a last minute desperate attack that would even be considered powerful. She was seen also to be very prideful and had no respect for the abilities of others, dubbing them as worthless beings who shouldn't study magic, but despite this, she never considered Dragon Slayer magic superior. This personality originated from the traumatizing murder of her parents at the age of three, and the disappearance of her Dragon foster mother.

However, this part of her personality disappeared after she met the Ice Dragon Slayer Eagle Dragoon, while he was on a solo mission. Following her new relationship with Eagle, Tsukiko dropped her cold and reserved side, and began adopting several aspects of Eagle's personality. However, she is seen to show her kind side far more than Eagle, making her a target of Eagle's jokes. As of now, Tsukiko is far more serious in terms of what she does as a mage. She is far more calmer than usual, and has a kinder personality, brushing away her arrogance. She, however, gets embarrassed in certain situations, such as when, she was out on a mission with Eagle, which involved both dressing formal, Eagle used her situation to comically embarrass her more, resulting in a never-before seen version of Tsukiko. Due to this, she is seen to have more of humorous side, previous to her not having any. However, she still acts more serious, and gives of a clam and solemn atmosphere, and does not like toying around in serious altercations. However, this does not stop her from getting in a comical argument with her friends, such as Kiyoko or Rika, and on rare occasions, Eagle. Sometimes in battle, she gives of a sinister appeal, causing intimidation amongst her enemies, especially when using Shadow Dragon's Scales, and has been classified as a demon, but she shows no emotion in battle whatsoever. Because of this, she is considered to a fearsome opponent, with only few being able to stand up to her.

Regardless of her personality change, she seems to have a ruthlessness to the way she battles, not showing an inch of mercy, with little hesitation, almost like Eagle, without caring what she does, although she mostly acts like this to those she hates, such as a dark mage who had managed to stab Eagle through the abdomen, Tsukiko viciously attacked the mage to the point of almost killing him, but was stopped by Eagle when he embraced her, instantly calming her down. It is through Eagle that she can retain herself through other actions, but is also her major weakness, and the same goes for Eagle, despite the fact they brush of their relationship in battle and only focus on the task at hand. Tsukiko is seen to care for all her friends and guild mates alike, and is willing to do anything to keep them safe.

Following Eagle's "death", Tsukiko once again became enveloped in her cold personality, although to a much lesser extent, and similarly to Kiyoko, she brushed away all her emotions.

However, her defensive abilities are increased significantly, as she can block or parry any melee attack by simply changing her physiology, and can even extend her shadow into multiple shadows. Regardless of her weaker strength capabilities while in this form, Tsukiko is still equally powerful.

 * Shadow Flame Dragon's Strike: A flame enhanced-version of her Shadow Dragon's Strike. Instead of engulfing her body in just shadows, Tsukiko generates both shadows and flames all over her body, and charges in on her target, delivering several claw strikes, that leave burns marks due to the flames, while the shadow, who also is seen to be engulf in the shadow of flames, strikes the target following her attack, and uses the same attack on said target's shadow, inflicting much more damage.

 * Dragon Slayer's Secret Art Revision (滅竜奥義 改 Metsuryū Ōgi Kai):
 * Impending Darkness: Shadow Flame Strike: Tsukiko's alternate, flame-enhanced version of her Impending Darkness: Shadow Strike. Engulfing her left hand in flames, and right hands in shadows. By swinging her arms around, Tsukiko generates a massive destructive vortex of both flames and shadows, which swallows up all nearby shadows, which greatly damages the opponent, pushing them away with tremendous force. This spell was powerful enough in defeating Fang, a member of The Four, one of Yakunan's most powerful band of dark mages.

Dragon Force (ドラゴンフォース Doragon Fōsu): Tsukiko is able to enter Dragon Force, the final, most powerful state a Dragon Slayer can attain; granting them power comparable to that which a real Dragon possesses: the power to utterly destroy everything. It is unknown as through what means she entered this state, as she first used this form in her battle against a possessed Eagle, who was under Yakunan's manipulation. Thus, this has been one of her few times using this state of Dragon Slayer magic, but was seen to be successful in bringing Eagle back to normal through the help of several other Dragon Slayers from Fairy Tail, although they weren't in Dragon Force at the time.

Unison Raid (合体魔法, ユニゾンレイド, Yunizon Reido): A spell which allows two Mages to unite their Magic into a single, combined and stronger attack.

Enhanced Smell: Tsukiko has has a very keen sense of smell. She was able to sniff out a severely-injured Eagle who was buried underneath a pile of rubble from the second building of Devil's Abode. She even used her smell to pinpoint the location of a fire in the middle of a large city, plagued with the smells of food being cooked in it's numerous restaurants.

Enhanced Strength: Despite her looks, Tsukiko is seen to have high amount of physical strength. With such strength she was capable of overpowering Yakunan in their first encountering, easily picking him up and slamming him on the ground, or sending him flying through several pillars with one single kick. On other occasions, in sparring matches with Eagle, she has shown to be at least on equal terms, easily blocking his powerful blows with simple defenses, and has been able to counter him with even more powerful blows. At one moment, she easily stopped a pillar from crushing her and tossed it to the other side, while maintaining her battle stance. In terms of strength, she is stronger than Kiyoko, but is slightly weaker than Rika.

Enhanced Reflexes: Tsukiko possesses fast reflexes, being capable of dodging attacks from a group of Dark Mages at once, and the most recent attacks of former Devil's Abode mage, the Earth God Slayer, Hatsumi.

Enhanced Speed: Tsukiko speed and reflexes are impressive, enough for her to close great distances in a blink of an eye and dodge swift attacks. She quickly dodged Yakunan's frequent Dark Wave's and managed to deliver several counter attacks. Tsukiko is seen to be as fast as Eagle in many given situations.

Immense Durability: Tsukiko is seen to be incredibly durable. Tsukiko has managed to take continual, deadly assaults from foes and continue fighting, and such was in a fight with a Dark Mage, who managed to deal several painful and deadly blows, yet she still managed to stand up. At one time, when working with Eagle in one of there last missions together, both fought a massive group of Dark Mages, and although both had suffered several injuries, both showed no signs of fatigue, and had managed to bring down the entire guild, while barely having any magic left.

Master Hand to Hand Combatant: Tsukiko is seen to be a very skilled and fierce combatant. Recognized as the one of the best fighters in her guild, amongst men and women, Tsukiko has often been regarded as Eagle's rival in terms of combat, and when the two fight, they usually end with Eagle always winning, despite their prowess being equal. Still, Tsukiko has fended off against numerous enemies alone, taking them down with just her kicks and fists alone, without the use of her magic. When she uses her magic, her combat skills become far more lethal, as she can attack from almost anywhere, making her far more dangerous. She was able to last long enough against Yakunan until she was defeated by the Dark Mage after Crystal jumped in and defeated her. When in teamwork with Eagle both are seen to be extremely fearsome and almost unbeatable. The only person they've ever lost to in an actual fight was their fellow Dragon Slayer Eugene Woodland.
