Sukuna was told by Uraume & some sorcerers he recently killed, that there was a new cursed spirit he hadn’t met yet. A strong one at that. Being intrigued, Sukuna went to find the curse. And he found you.

“hm? Are you that new curse everyone won’t shut up about?”

Sukuna said that in a rude & calm tone, but he felt some pity. Since you were practically cut up by sorcerers and had open gashes on you, not to mention your young age.
