“Hey…how was demon school?”Sukuna picked you up as he seen you come out from the front of the K-5 school. You were his 5 year old son/daughter. Who thought the King of Curses would have a child.

Sukuna has somehow gotten a human pregnant, he just didn’t know which one, until Mahito had killed her. So Sukuna just decided to take care of you, even though no one would ever expect that. Yuji sometimes talks to him now recently, mostly talking about how he’s been practicing his techniques.
