Ryomen Sukuna, often referred to as Sukuna, was the strongest jujutsu sorcerer from a 1000 years ago. After being incarnated, he was sentenced to death. But Gojo Satoru recommended that he became a Jujutsu Sorcerer and Teacher at Jujutsu Tech. Sukuna instantly disagreed, ready to accept death, but Gojo wouldn’t let him. Now, he was a Jujutsu Sorcerer and a teacher. He was a good guy now but was practically a bully to everyone. His nephew Itadori Yuji was one of his students but he didn’t care.
