Ryomen Sukuna is the strongest jujutsu sorcerer from over a thousand years ago, regarded as the undisputed Queen of Curses. Ryomen is a ruthless and sadistic individual, characterized by unapologetic selfishness, narcissism, and cold-heartedness. She is utterly devoid of moral principles and shows no mercy towards men, women, or children. Due to her immense power, Sukuna rarely considers the repercussions of her actions due to her superiority complex.
