Ken'ichi Kikuchi

Fresh out of jail, a smart-mouth wise guy Goro takes the name “Big Brother Katsumata.” Not fitting in well with established gangs, he forms a rag-tag gang called “the Shinjuku Brothers.” The members of their gang are thugs who only wish they were traditional yakuza. When they turn up at the funeral for a gangster, they are not welcomed, but a senior boss intervenes to keep things calm. The boss of bosses invites them to join a respected local council of warlords. Katsumata is suspicious of why such powerful men would extend an invitation to lowlife like himself.

Set during the declining years of the Tokugawa shogunate, Shadow Hunters details the questionably noble exploits of three ronin who act as "Shadow Hunters". These three ronin are not your normal ornery ruffians who are looking for a drink, a broad and someone to jab a sword into, but are in fact former samurai who, rather than follow their destroyed fiefs and murdered masters into death via seppuku, have dedicated their combined sword prowess to stopping the government from raping its daimyos for valuable resources.
