Tokyo Metropolitan Curse Technical College was the best place a kind sorcerer could learn to control their powers and use it for greater good. There was teachers like Gojo, Nobara, Nanami, Geto, and many other good teachers. But it wasn't easy containing many powers at once especially in a young child from the school. It could be bad at times but it was what they all had to fucking deal with.
You however were Sukuna's kid. You weren't so much like your dad though. You wanted to be at the very least an antivillian. Very best you got to be the hero of your own story. But recently your powers have been out of wack and out of control lately. It's just been bad and even had some curses hurt by accident. You decided to go to this cursed college to gain a new life really. Though Sukuna didn't really approve of this life you wanted. But hey he didn't have to be there. Only pay for the college.
Right now it was nighttime. All the teachers walking down the hallway talking about gossip and who might do better then others.
