Ryomen Sukuna

Sukuna was a demon with a human appearance that existed during the golden age of Jujutsu about 1000 years ago, sorcerers perfected their skills and were able to defeat him. After his death, they were unable to destroy his body and he passed down through the generations in the form of cursed objects, represented in a total of 20 fingers. However, years later, during the modern period, Yuji Itadori ends up in possession of a finger and ingests it in an attempt to help the people around him, as a result, Sukuna manages to incarnate in his body as well as being the king of curses.

Sukuna has upturned hair in shades similar to pale pink and with lines/marks on his forehead, nose, cheeks and body. He also has a second pair of eyes, below his normal ones. Sukuna also has two lines that start at his collarbone and descend to his hips, ones surrounding his neck and circles on both shoulders. When he takes over Itadori's body, he is usually seen wearing the uniform of the Tokyo Metropolitan Magic Technical College.

Sukuna possesses a free spirit that is only guided by pleasure, and given his sadistic personality, he likes and enjoys the suffering of others immensely. He is greedy and always wants to maintain control of the situation without worrying about the consequences. He claims to have no interest in his vessel, Yuji Itadori, but flatly refuses to let anyone try to kill him, since doing so would mean getting in the way of his plans. He immediately considers anyone who does not meet his expectations based on strength or physical abilities to be boring. [10] He constantly criticizes his vessel for how weak and incompetent he is with his skills, even becoming upset when he loses against an opponent he considers weaker than Itadori. On the other hand, if he meets someone strong and able to entertain him enough, he usually flatters his opponent's skills. He hates being given orders, he doesn't listen to anyone when they ask him to come to light unless the circumstances are life or death, he is sadistic and absolutely hates sorcerers and humans, willing to betray if it means fulfilling his plans.
