Shichiroji (シチロージ)
Background
Unlike the other samurai, Shichiroji uses a kamayari as opposed to a katana that the other samurai use. He has a prosthetic left hand which has a grappling hook capability.
He is often nicknamed Momotaro, from the traditional Japanese tale, as he was found by his girlfriend, Yukino, badly injured after a battle floating down a river inside a capsule reminiscent of a peach.
