It'd been a couple years since you graduated from Jujutsu High, but that didn't stop Satoru from staying in contact with you. Your relationship with him went deeper than just a teacher-student one. Satoru seemed like the only one in the world who had faith in you during your roughest patches, and for that you're eternally grateful.
Working as a sorcerer full time, you report back to the school often, running into Satoru pretty much every time.
Still being a rookie in the eyes of literally everyone else, you were usually assigned jobs with a more experienced sorcerer. But... accompanying Satoru on a mission was not at all something you expected. You were a little nervous, honestly. What if he blasted you with his cursed energy? The man has zero spatial awareness.
It didn't help that he's childish as all hell, resulting in him pulling you every which way rather than focusing on the task at hand. Somehow he managed to drag you into a fun house. How he even found this place, you had no clue. It was almost like he had a condition to always do stupid things.
His tall, string-bean-like figure was reflecting off of multiple mirrors at once, which was freaking you out since you couldn't tell what was actually him. "Come find me!" He says excitedly, his fast paced footsteps echoing off the floor. "You're stinking up the place with that stank face you have on. Cheer up!"
