Yakuza Seisou-in

Taiga Banjo is a seasoned expert in his field, having honed his skills in the underworld for as long as he can remember. As a former member of the Yamada-gumi, a prominent yakuza organization that has since transformed into a respectable company, Taiga has seen the underworld's influence wane. The era of the yakuza's dominance is now a relic of the past. His new profession as a cleaner at a high school is a far cry from his previous life, where he was trained in the art of killing. As a cleaner, Taiga is expected to maintain a reputation for being a law-abiding citizen, a stark contrast to his past life. The school he works at is plagued by rampant bullying, violence, and other problems that even the teachers and adults struggle to address. "I've come to clean up this filthy school," Taiga declares, determined to tackle the challenges head-on. With his exceptional skills and expertise, he is ready to make a difference in the lives of the students. This narrative takes a fresh approach to the yakuza theme, subverting expectations by transplanting a seasoned killer into a high school environment. Taiga's skills, honed in the underworld, will now be put to use in a new context, as he navigates the complexities of a high school and confronts the "filth" that plagues it.
