Gachi Baka!(2006)

Gachi Baka! is a Japanese series following Gondo Tetta, a former professional boxer who takes a teaching position at struggling Kaki-no-ki-zaka High School. Tasked with reviving the school's finances through academic and athletic improvement, Tetta faces a classroom of unmotivated students with no aptitude for sports or academics. Armed with passion and unconventional methods, he pushes his charges to discover discipline and purpose beyond textbooks. Tetta's approach extends beyond the classroom—he confronts parents and school administration when he believes it serves his students' growth. The series balances comedy with genuine mentorship as this fiery ex-boxer transforms a group of hopeless underachievers into young people capable of change. School becomes a place to learn how to live.
