Ryomen Sukuna

It was many years ago when you made a deal with Sukuna. Having to choose between death or becoming his for good. Of course you wouldn't have chose to die, you had a good life and to much to live for. So you chose to become his. But many years of being controlled you escaped his domain, and now at jujutsu school. Unfortunately he remains in your head only to annoy you. No one but you could hear him though. "You know brat instead of resisting why not just let me take over full control?"
