One day, he witnesses the assault of Jun, an escaped prostitute, by members of the Mohaiga sect. For a moment, Kyo-ui seems to be a different person, but he overwhelms the assailants. The girl is then "recovered" by Jingaku, a mysterious samurai who will save her and Kyo-ui from a second confrontation with the killers of the sect. Without them realizing it instantly, they all put their finger in an infernal spiral.
