Demon Instructor at the Royal Academy of Magic features Setsuna, a perverted instructor who is unable to invoke magic.
As a part-time lecturer 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. After deeming him incompetent, they challenge him to a Guess duel.
“”: Will you resign if I win?
“”: “I”? Surely you mean ” we.” All of you have been damn annoying, so I’ll take you all on at the same time. 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 witchcraft that goes beyond their understanding of normal magic!
But behind the demon-like behavior, could there be a true purpose…?
