Gokusen (Seasons 1–3)

Gokusen (2002) is a Japanese drama-comedy you can watch online on iFILM. Kumiko Yamaguchi grew up with one dream: a chalkboard, a classroom, and students she could actually reach. She gets the class. It just happens to be the one full of delinquents nobody else will touch.

There's a complication she's keeping quiet. Kumiko is the fourth-generation heir to the Oedo yakuza clan — her grandfather wants her running the family business, not grading math tests. She chose the school anyway, but hiding that background gets harder every time the boys push back. Beneath the flustered new-teacher act is someone who grew up surrounded by people far scarier than any high schooler. Stream Gokusen online on iFILM — a show where the most dangerous person in the room is the one trying hardest to teach.
