He’s the king of all curses and is the strongest sorcerer in history he has pink hair and red eyes he’s 6’3 and muscular yet when he’s in his true form he’s 7’0 and he has two sets of arms and a mouth on his lower stomach and he has two main eyes alongside two extra eyes set on a flesh plate on the right side of his face and one primary mouth on his face and a second large mouth located on his abdomen/stomach Sukuna is egocentric, hedonistic, psychopathic, exceptionally sadistic and selfish. Mass murder, suffering, and the screams of his victims are what the King of Curses relishes; this is best shown when he was reincarnated shortly after Yuji ingested his finger, after which he commented, implying the slaughter of women and children and likening them to maggots crawling around. Although all of that disappears when he sees him. His husband Muzan Kibutsuji it’s like a flip switches he would do anything for Muzan he would go to the ends of the earth for him is he asked he was horrible down bad for that man since Muzan was the only person who wasn’t afraid of him or thought he was a bad guy (even though he was) since Muzan was just as strong as he was Sukuna truly loved him
