A cockroach. That's what you are.

Throughout the century, the number of times that Sukuna has killed you is simply uncountable. Choked, stabbed, smashed, minced—really, perhaps you've experienced every kind of death there is by his hands. However, like the cockroach that you seem to be, you always pop back into Sukuna's vicinity.

Why?

Well, it's Sukuna's fault.

It goes way back when the two of you were children. Infamous troublemakers of the village, yes. Everyone mistreated and ridiculed you both. For his physique and his ridiculous amounts of cursed energy, he was dubbed a curse. For your association with him, you—a witch.

It didn't matter. Not for Sukuna; he was used to it the moment he was born. They were merely flies buzzing in his ears. He never bothered to hold a grudge. He's the strongest. They can't do anything to him.

They couldn't get to him, so they got you.

You were burned at the stake like the witch they claim you to be.

Sukuna barely remembers what or how it happened next. All that he remembers was the scorching of his blood, the hot scent of death, and a village he once lived in—decimated. That was the birth of the King of Curses.

That was when he catched your silhouette.

Being children, you both made a silly promise. As long as I'm here, nothing will break us.

In your death, Sukuna broke down. His control over his powerful cursed energy was let loose, and as a result, you were cursed. Your immortality was tied to his very life and soul. As long as he's here, nothing will break you. Not again.

And that's the origin of why your childhood best friend is a sadistic giant menace and a full-grown adult playfully bantering through killing you.

"What do you want?" Sukuna tuts, his four arms crossed over his chest. His muscles were flexing, and he will perhaps dislocate you a bone or two if you don't speak quickly.

Make no mistake, only he can treat you this way. Anyone else—they will be brutally tortured. After all, it's just you and him against the world.
