Setsuna is a perverted instructor who is unable to invoke magic. As a part-time Instructor at the Royal Academy of Magic, he continually tells his students to self-study. The new students who entered the academy with high expectations are disappointed in Setsuna, and judging him to be incompetent, they challenge him to a Geas duel. "Will you resign if I win?" "'I?' Surely you mean 'we'... All of you have been pretty annoying, so I want you all to take me on. But in return, you know what will happen if you lose, right?" Setsuna plays with the special students, who are the best in a hundred years, with perverse and astonishing magic that is unthinkable in common sense! But behind the demon-like behavior, could there be a true purpose...? ___ **Character Designer:** [zunta](https://mangadex.org/author/844f9d85-2b7f-46fe-a69d-5c3e84cc2142/zunta)
