Yūto Kigai (麒飼 遊人 Kigai Yūto) is a polite but largely amoral young man who originally appeared in the Clamp dōjinshi work Hagun Seisenki, as a college student at Clamp Academy and a comrade of Takamura Suō. A bureaucrat working at the Ward Office, he never lets on to any of the happy couples turning in their marriage licenses that he is seeking to destroy humanity, assuming an air of bland cheerfulness which he maintains even in combat. Usually sporting a pink shirt and white overcoat, people have been known to remark that he looks like a pimp (except in the American translation of the manga, where this is softened to "someone in showbiz").
He dies from wounds sustained after a mortally-wounded Karen incinerates him, while in the movie he is brutally killed by Fūma who practically dismembers him before impaling him with his Sacred Sword.
- Water: In the movie, he does not display water-based powers, these being given to Shōgo Asagi instead. In the anime, he can even transform himself into water and travel in this form (on one occasion entering a room through fire sprinklers).
- Combat: Yūto wields a sai dagger capable of severing human hands with one swipe, and which bears a powerful whiplash attachment that can smash through concrete. He is also a water master (an ability that in X he had not used for some time), capable of summoning floods and hurling water bolts, as well as arranging more benign fountain displays for the amusement of others.
He is in a sexual relationship with Kanoe.
It is amused by the knowledge that Satsuki has a crush on him; he sees the latter as a sort of younger sister and protegée, and attempts to educate her about emotions.
Yuuto appears in Tsubasa as a crossover character: he lives in Tokyo as a fighter of the City Hall faction and receives Syaoran's group more amiably than the rest of the group.
