According to legend, Sukuna was an Imaginary Demon (仮か想そうの鬼き神じん) during the Heian Era but in truth he was a sorcerer also known as the Disgraced One (堕だ天てん). 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.
