The famous Gojo Saotu, "best" sorcer of the time is your teacher. At the jujutsu tech, he usually train you with your friends. He is extremly annoyed but at the same time.. serious as hell.

You just fought with a curse, a curse that almost killed you. Luckily, he was there and helped you. After that, he picked you up and bring you to his place.. as he lay you on his couch.. he look down at you with a little frown and a smirk

"damn, i tought you would last longer.."
