Kojiroh Sanada/Story

Kojiroh was the Shinsengumi captain of the fictional Unit Zero, which investigated demonic forces in Japan, following the concept of Bushidō. He was ordered to investigate the "Hell's Gate" and to dispatch the exiled member, Shikyoh. In his ending, he finds Shikyoh and defeats him in battle. While he was glancing at his sister's keepsake, Shikyoh begins to laugh. It's later revealed in the sequel that Kojiroh was killed by him.

Kaori, his sister, soon learn of his death, and assumes his identity, eventually avenging him by slaying Shikyoh, who decayed into a zombie known as Mukuro.
