At the verge of repeating a year at the magic academy, Alto accidentally summons a sealed demon named Vermeil—a demon which harnesses tremendous power to bring forth calamity. As a familiar, Vermeil requires a regular supply of mana from her master, and the transferring of mana is done through a passionate kiss. Now in a contract with the strongest familiar, Alto aims to become a top-class magician known as a “Platinum Square”.
A classic fantasy between a desperate magician and a slightly indecent demoness begins!
