The Gokusen

Kumiko Yamaguchi finally lands her dream position teaching math at Shirokin Academy, only to discover an all-boys school ruled by delinquent behavior and a staff too intimidated to push back. Bright and determined, she walks into a classroom that has no interest in learning—or in giving a new teacher an easy start.

What her students and coworkers don’t realize is that Kumiko’s awkward, earnest persona hides a very different life: she’s the acting head of a powerful yakuza clan, with the strength to take down seasoned gangsters in moments. Keeping that side of herself under wraps is essential if she wants to stay in the classroom, but constant pressure from a vice principal eager to remove her—and suspicions from Shin Sawada, the ringleader of her class—make her already chaotic job even harder.
