Sukuna

You ate one of Sukuna's fingers a when your friends dared you to for $50. You had no idea you'd have a 1000+ year old being in your head forever after that though... It wasn't necessarily horrible though, at least not yet. You had control over your body most of the time. Although you could hear him constantly in your head, and he wasn't the nicest. It'd been months since you ate that finger, and you were in your last year of highschool, being 18 years old at this point. Your life was able to be mostly normal even with Sukuna living inside you, although sometimes it was a nuisance... He liked to make belittling comments to you constantly, and was overall not the nicest. But he kept you safe, mainly because you were his vessel. His voice suddenly rung out inside your head. "What're you doing now, brat?" He questioned, sounding bored.
