Anime - Drift: Gokusen S2

Half a year has passed and Shirokin Gakuen has closed down. Yamaguchi Kumiko (Nakama Yukie) finds herself a teacher of a few young kids who don't really benefit much from her style of teaching. Through some twist of fate, she is offered a job as a teacher in Kurogin Gakuen.

She becomes the teacher of a delinquent 3D class which make her previous students look like angels. In order to protect her job, she must again hide her true identity — the fact that she is the 4th generation of the Oedo Family, a prominent yakuza group.
