START-419 A nagging schoolteacher who missed her chance to marry is a very eccentric pervert with a hobby of indecently exposing herself on campus during class. When her hobby is discovered by the students, she is made to act like an animal and begins to rediscover her instincts as a woman. Tadai Mahiro

Yuii-sensei, who always wears a tracksuit and has a tomboyish personality, is strict and constantly lectures a group of not-so-bright male students. Behind her back, the students mock her, saying things like, She definitely doesn’t have a boyfriend, She’s probably never even dated, and She’s completely missed her chance to get married. But in reality, she has an unusually strong libido and is a total pervert who takes advantage of empty times during class or after school to secretly expose herself around the school and indulge in private pleasure.
