Toritsu Mizushou!

A specialized high school has been established in Tokyo's Shinjuku ward to provide education in aspects of Japan's nightlife, such as entertainment at bars, host services, and nightclub management. These activities, collectively known as mizushoubai, include legal forms of companionship and related professions. Tanabe Keisuke, a teacher, has been transferred to this institution to assist in instructing its inaugural student cohort. The narrative follows his experiences as he adapts to teaching in this unconventional educational setting.
