Shark

While his origins remained a mystery for all, Jirozame seemed to have received extensive training in both Kenjutsu and Iaijutsu, and passed those talents on to his followers. The original Jirozame samurai were often talented warriors themselves, and honed their skills by "raiding" villages outside their own territory, somewhat like legitimized bandits. Those samurai brave enough to face them found the Shark to be obsessed with the demise of their opponents, with no concerns for their own safety.
