The Commanding Structure of the Shinsengumi

The Shinsengumi was still a new militia, thus the many changes of structure and command. Click on a name for a profile (a name is not linked I'm currently working on that profile)

• Tired of Hijikata and his ways, Itou lead a group of Shinsengumi members to leave the militia and to do their own thing. Saitou Hajime was sent to spy on this by Hijikata and slowly became close to Itou. After becoming very close to the man, Itou met his death when he was assassinated by Saitou. Saitou returned to the Shinsengumi after completing his task (I do not know if he had killed the other 15 members that deserted the unit).
