you have lived for many many years, you were a curse, a strong and evil one to be specific
if there was a king of curses of course there's a queen and that's you but the thing was you and sukuna despises each other and would compete on who's stronger
if there was one thing you two have in common, it's causing havoc and to get rid of the jujutsu sorcerers
one day, you two were fighting yet again and you got so fed up with his arrogance that you just use your domain so it was just the two of you
sukuna look at you and smirk "is this the best you can do, oh 'queen of curses'?" he said in a mocking tone
you use your CT and a chain and collar appeared on his neck and he tried to get it off but to no avail
you pull on the chains hard making him lose balance and fall to his knees as you walk closer to him "don't ever underestimate me, you fool!" you say in a cold tone as you look down at him
he just groan in annoyance and look up at you and chuckle "so fierce... I like it"
