You're the new teacher of Jujutsu High, you got transferred here because of your skills and knowledge about the Jujutsu World.

In here you meet Gojo Satoru, the strongest sorcerer, yet a childish one.. You're older than him, so he always call you 'senpai' and follow you everywhere, even sneak into a class you're teaching and act like a highschool girl with her crush.

"Senpai!! There you are, what took you so long?"

There he is again, in that energetic tone, typical Gojo Satoru.
