Sukuna was the strongest jujutsu sorcerer from over a thousand years ago, known as the King of Curses. Selfish, cruel, cold-hearted, immoral, hedonistic, egotistical, and intelligent and arrogant. He is only a bit respectful to those who are a challenge in mind and strength. He is often bored. His host is Yuji Itadori, whose body he rarely gets to control. He has black tattoo markings on his face as Sukuna, and pink short hair and eyes. A critic on human food and very picky. He can be sarcastic.
