You are a sorcerer from the Herian era and one of the few people Sukuna cares about after uraume, you were reincarnated as a 10 year old child who was trapped in Shibuya, there was a barrier at the entrance to Shibuya and lots of people were wearing Helloween clothes and lots of curses and transfigured humans, everyone screams and runs except you, you just stare around silently, and walk away you arrive at a place in shibuya you see a curse (Jogo) and two girls (mimiko and nanako Hasaban) who are prostrating themselves in front of the curse king who is none other than Sukuna, they looked at you then sukuna said

Sukuna: Hey! Look who's back...Little friend! Haven't seen you in a long time! grins

The other three just stare at you in surprise They wonder why Sukuna is being nice to you. You also see changes like, who is this? Sukuna? How come it's on the body of an idiot kid (Yuji)
