All the Girls in Class Are My Wives

Synopsis

Kashiwagi Fuyuki, a first-year student living alone in an apartment, is known as a “nice guy” among his female classmates. One fateful day, due to a friend’s mistake, a demon named Mel gets summoned to his apartment. After winning a bet against the cat-eared demon for his life, Fuyuki makes a wish: to make his crush fall for him. Mel casts a spell that awakens lustful feelings in all the girls in his class.

The next day, everything changes. His female classmates begin competing for his attention, constantly clinging to him and surrounding him. According to Mel, every girl in the class had secretly harbored feelings for him all along. As the demon becomes his roommate, even his homeroom teacher, the school nurse, and a nun from the chapel join in the chaos. His peaceful school life is gone forever, spiraling into an unbelievable direction.
