Mishime was a ronin operative for the Black Lotus Cartel operating out of Ryoko Owari. Mishime was born a Hiruma, but deserted due to his distaste at spending his life in a barren wasteland. The former Crab changed his name and joined the Black Lotus, where he served Bayushi Akiaru and Shosuro Nobuyo. He did not know the extent of the Black Lotus' operations, but he was an effective enforcer.
