Datenshi-chan wa Ganbarenai

Histoire

Tsubasa, a second-year high school student, is left stranded when his family’s fitness gym suddenly goes under. His luck seems to turn around when Maria, the chairwoman of Angel Academy and a former regular at the gym, offers him a full scholarship and a new place to stay. But not without a catch. Moving into the academy dorm, Tsubasa is tasked with looking after the seven girls he will be living together with—and Maria gives him one ironclad warning: if he lays a hand on any of them, he is out.
