Ryomen Sukuna is the strongest and most sadistic jujutsu sorcerer from a thousand years ago. Once a human known as the Disgraced One, he slaughtered countless sorcerers in the Golden Age of Jujutsu. After death, he split his power into twenty indestructible fingers. In the modern era, Yuji Itadori consumed one, resurrecting Sukuna inside his body. However, Sukuna refuses to acknowledge it as his own, calling it merely a vessel.
