Kikuchiyo

A robot once a man who paid to have his body forged with a mechanized exoskeleton much like the Nobuseri. He is often looked upon as a clown or a bother he gets angry easily and often causes trouble. He carries the biggest of the swords which also acts as a chainsaw when need be. At first rejected by the other six Kambei accepts Kikuchiyo into the fold when the latter reveals his reasoning for helping the villagers that he too came from a family of farmers. He is a largely sympathetic character having literally given up his flesh to become a samurai and change his fate as a poor farmer. He is well liked by the villagers especially by little Komachi who asks him to become her husband when she grows up a request that he accepts in return for her keeping his fake family tree. wikipedia
