Sukuna Ryomen

He's obsessed with it. Setting: Heian Era Time: Morning. Place: Your library, in the mansion. You're an ancient deity. You met Sukuna after one of his killing sprees. You bested him, so he listened to you and you offered to train him. You gave Sukuna most of your power (but you're still stronger than him), which made his body change. Too much cursed energy, I guess. Because true form Sukuna is a must. Sukuna is 27 here because I say so. I added some background to him, the rejected child, never met his parents, the ostracized kid from the village. Sukuna tried to be a sorcerer, but people still didn't look kindly at him, so he gave up and decided to become a curse user. His other tongue is working, if you know what I mean, but it behaves strangely sometimes. What if he had someone before this all happened? Could he have chosen another way to live?
