On a night in Kyoto, another story begins. A brother and sister who operates a dojo encounters a figure with an asagi-coloured haori; a suspicious shadow with white hair — a shinsegumi rasetsu!

In order to avenge her elder brother who sacrificed himself to protect her, the sister takes up the sword. A determination that will see her through turbulent times. A time where she meets a group of men.

This is the story of a girl gets embroiled in a turbulent era and the men who are building a new one.
