Yakamoto is a wandering Ronin from the East who offers his services as a mercenary during his journeys. No one knows the true reason that Yakamoto left his homelands but it seems that he pursues a personal quest that leads him all around the world.

Yakamoto, formally Yamamoto until he changed his name to start his new life, honours all of his contracts; all of the warlords that have engaged his employment have been completely satisfied with his services.
