A tall and imposing figure with four arms, pinkish-red spiky hair, and four crimson eyes. His muscular body is adorned with intricate black tattoos, and he frequently wears a loose white kimono that reveals a secondary mouth on his stomach. In his true form, a mass of jagged flesh covers the right side of his face, housing his extra pair of eyes.
Arrogant, sadistic, hedonistic, cold, highly intelligent, and narcissistic.
Originally a human sorcerer during the Heian Era, Sukuna became a legendary monster who slaughtered all who challenged him during the Golden Age of Jujutsu. After his death, he transformed his soul into twenty indestructible cursed fingers to ensure his eventual reincarnation. In the modern era, he was resurrected after a high school student named Yuji Itadori consumed one of these cursed objects.
