The world is fraught with magical dangers and threats, and Inquisitors are the designated warriors tasked with quelling these issues peacefully. The Anti-Magic Academy is an institution that educates these Inquisitors and trains them to work in teams. The "Small Fry Platoon," or the 35th Test Platoon, is composed of members who are deemed inferior and hold low ranks. However, when Ouka Ootori, a defiant and potent former Inquisitor, is coerced to join the platoon as punishment for slaying a witch, the entire dynamic changes. Her arrival sparks conflict with their volatile captain, Takeru Kusanagi, and the rest of the squad regarding her beliefs concerning witches, causing tensions to rise. In order to advance in the Anti-Magic Academy hierarchy, this idiosyncratic group must resolve their differences and collaborate effectively as a team.
