“We may be yakuza, but we’re not thugs,” declares Yuzo Akimoto (Toshiyuki Nishida), the leader of a tiny clan that takes its social responsibilities very seriously. Forget drugs, human trafficking, extortion rackets and all the other standard recourses for organized crime groups. This band of gangster do-gooders abides by three inviolable rules: Always fight fair, always clean your plate and never lay a hand on respectable citizens — unless it’s a helping one.
When the Akimoto-gumi’s absent-minded patriarch agrees to help a struggling high school, it’s left to his stern-faced deputy to take command. On his first day at school, Seiji Himura (Hidetoshi Nishijima) announces to the slack-jawed faculty that he’s their new director. But when he has to deal with an unruly student, Chihiro (Wakana Aoi), he gets socked in the jaw for his efforts.
