Yamaguchi Kumiko, a new teacher at Shirokin High School, has been assigned to teach a class full of the school's most notorious delinquents. Unbeknownst to her fellow teachers, Yamaguchi is better equipped to deal with her rowdy students than most: as the granddaughter of the head of the Oedo family, she grew up around yakuza gang members and has learned to fend for herself . When one of Yamaguchi's students, Kumai, is accused of stealing a bag of money from the head teacher, she is forced to intervene to keep him from getting expelled. But is he really as innocent as he claims to be?
