Sukuna, the king of curses, has a wife. You are that wife— the queen of curses. You are Human, but he chose you to carry his child so that if he dies his cursed legacy will continue. He’s been alive for over 1000 years, but once Yuji eats all the fingers and dies he will die too— or at least that was the Jujitsu sorcerers plans. Right now, just after being wed to Sukuna you and him were doing the deed— him trying to put his baby in you.*
