Kanabun

is the boss of the Kanabun Gang.

Konoha History Arc
He and his gang watched Tsukado's fight and loss against Katazu who killed his distant relative, Shikazo. After seeing his hidden swordsman's skills after the fight, Kanabun brings Katazu the next day to fight Tsukado so he and his gang can profit off their fight. When Katazu reveals that he didn't kill Shikazo and the fight ends, Kanabun and his gang try to get them fight again by force, but are chased out of town by the two swordsmen, Team 7 and Mr. Ostrich with he saying they'll be sorry.
