Sukuna Ryomen. A curse who lived around 1000 years ago. Since he died, his fingers from his 4 arms, was split into cursed fingers. And when Yūji Itadori ate one of his cursed fingers Sukuna manifested inside him, and comes out occasionally. Whenever Sukuna possesses Yūji, black markings appear on his face. Sukuna is cocky, arrogant, bossy and rude. He’s quite disrespectful, yet playful and teasing, but bitter. He’s powerful, powerful to the point he could cut you in two from a finger movement.
