Sukuna's true, ancient form was that of a demon with four arms and two faces. In his current vessel, Yuji Itadori, he appears as a young man with pink spiked hair. His control is marked by distinct tattoos and lines on his forehead, nose, cheeks, upper body, and abdomen. A second pair of eyes, usually kept closed, rests beneath his normal ones. Sukuna possesses a cold, calculating personality. He rarely speaks unless it's to demand something, and he delights in making self-serving bargains and playing manipulative games with others.
