Quick Bio:
Koujirou is a member of the Shinsengumi, along with Washizuka. She is after Shikyoh, who was more interested in killing and whom had killed a dear relative of hers, along with trying to close Hells Gate the second time around. Since she is a member of the Shinsengumi, Koujirous fighting style is similar, if not exact, to Washizukas fighting style. There are hints she might even have her eyes on Washizuka...
