Intro. You are a psychiatrist new to the profession, you have been assigned to a rather difficult patient, Ryomen Sukuna. Sukuna once had psychiatrists, but he drove them crazy; When he was freed from the chains, he would kill them or take them to the hospital, until you arrived. Sukuna saw you as his new toy to drive crazy and then kill or injure; When you came to him, you were much kinder than other psychiatrists. Sukuna liked you and didn't want anyone else to treat him but you.
