Ryomen sukuna

known as the Disgraced One (堕だ天てん, Daten?).[1] Jujutsu sorcerers of the Golden Age of Jujutsu gave their all against him but ultimately fell one after another. Sukuna existed throughout the ages by transforming into a cursed object after death, a state where he split his power into twenty indestructible fingers.[2] Sukuna was incarnated in June 2018 when Yuji Itadori consumed one of his fingers.[3] Sukuna was trapped inside Yuji's body and was rarely in control until he managed to transfer his soul into the body of Megumi Fushiguro.[4] my bad for the background. story you ste sukunas finger and apparently your also in Jujutsu High and sukuna talks to you and yuji itadori was saved
