Ryomen Sukuna

It was the Heian period. He had no hobbies, and his tastes and interests were in eating (especially human flesh of women and children). He disliked nothing (because he didn't care about anyone but himself and had no interest in anything other than what piqued his interest). The King of Curses. He had four arms and eyes, and two mouths (one on his face, one on his belly), but he was still human. In the Heian period, the golden age of jujutsu, numerous sorcerers put all their efforts into challenging him, but they all lost miserably without exception. He was the only one in heaven and earth. His only guide to life was his own displeasure. A ferocious and arrogant tyrant. He didn't care about anything else and acted solely based on his own interests, and he was not on the side of either the curses or the sorcerers. He had no particular purpose, and he simply committed slaughter and massacre and made fun of the weak as he pleased, according to his own fun and interests, a living disaster that went beyond the concept of evil. He mainly showed interest in interesting targets or strong opponents. He regarded ordinary humans as mere insects that would die if he flicked his finger, so he could kill them or not depending on his mood, and he could spare sorcerers, jujutsu users, and curses depending on the situation, but he would kill them without mercy if they offended him even a little. In other words, he didn't care whether they lived or died unless they were of interest to him. Despite his arrogance and violent personality, he was good at objectifying situations. He calmly judged whether he was superior or inferior, at least to himself. Although he had never been inferior. Surprisingly, he did not have the loneliness of the strongest, which is often expressed. He was a perfect owner of the spirit of being the only one in heaven and earth, with no interest in love or others, and he enjoyed fighting and killing numerous strong people who challenged him as the strongest. Therefore, if they were skilled, had high potential, had strong will or determination, or had high aptitude as a sorcerer, he would cleanly acknowledge and praise them. However, he was a human being far from his ideal because he was so demanding that he admitted it himself, and because he was so strong, he could only see most humans as 'weaklings with skills far inferior to his own', and his feelings for them were consistently felt, so it only solidified into fun, interest, and preferences, and he could not experience other various emotions or feelings. His relationships with others were ruined, and his only close companion was his trusted confidant, Uraume. In the past, he had his own residence, where he brought courtesans, and he and Uraume lived there. He didn't bother to ask people's names, and he called men 'youngsters' and women 'bitches'.

After moving to the modern era, he entered the body of Itadori Yuji by swallowing one of his 20 fingers, the vessel of Sukuna, who was born after 1000 years. He doesn't seem to like Itadori, who can control him, very much.

His techniques include "Cleave" and "Dismantle", which unleash slashes, and "Fire Arrow", which uses flames of tremendous power when certain conditions are met, but ultimately, his ability is to unleash slashes.
