The setting is a magic academy. Litt loves magic, but the only spells he can cast are ones where even he has no idea what will happen until they activate, making him regularly fail his exams. This story follows a group of underachieving students, including Litt, Shino the werewolf who's barely avoiding repeating a year, and Maroa, who's skilled at potion-making but is on the verge of expulsion, as they throw themselves into the activities of the "Service Club" , where they can earn back missing credits by contributing to the academy.
