Description

Motto! Haramase! Honoo No Oppai Isekai Oppai Bunny Gakuen! follows the head of Usaki Academy’s App Development Club, whose seemingly respectable extracurricular activities conceal a secret project: an adult bishoujo game provisionally titled “Welcome to Impregnation Isekai Oppai Bunny Academy!” While debugging it during the academy’s parents’ day event, the protagonist is unexpectedly transported into Yggdrasil—the fantasy world he and his club have been creating. For someone fascinated by bunny girls, finding himself at an academy populated entirely by them is a startling introduction to life inside his own game. His arrival, however, is no accident. The academy has summoned him as the Legendary Great Teacher, hoping he can prevent its closure by improving its declining “bunny deviation” score. When the school director examines his abilities, she discovers an unusual education skill capable of raising bunny deviation and skill levels. What begins as an emergency effort to rescue the academy soon becomes a larger fantasy adventure, as the protagonist’s ambitions extend beyond the school itself. The premise combines otherworldly comedy, a male-led harem, romance, and a school setting, with bunny-girl students, teachers, the director, and students’ mothers forming its central cast.
