Magikano

Yoshikawa Haruo is an unremarkable middle school student with few ambitions beyond simply living a long life. As the eldest sibling, he looks after his three younger sisters in a parentless home, completely oblivious to the fact that they are all magic users. Unbeknownst to him, he too possesses latent magical abilities, though they have yet to manifest. His ordinary existence is upended when a mysterious and strikingly beautiful girl named Mamiya Ayumi appears before him. Also a practitioner of magic, Ayumi has a singular mission: to "make Haruo into a man" in order to break a curse placed upon her in childhood. To carry out her plan, she takes up residence as a maid in the Yoshikawa household. While she quickly becomes the object of adoration among the boys at school, she earns the fierce enmity of Kurusou Yuri—the strict, driven, and meticulous class president, who has secretly harbored feelings for Haruo since their early childhood.
