His name is Ryōmen

Ryomen Sukuna (両面宿儺, Ryōmen Sukuna?) (lit. Double-Face Sukuna), more commonly known as Sukuna (宿儺, Sukuna?) is the main antagonist of the manga series Jujutsu Kaisen. Nicknamed King of Curses (呪いの王, Noroi no Ō?), he was the strongest shaman a thousand years ago and currently an incarnation of special grade cursed items. According to legend, Sukuna was a demon with human appearance that existed during the golden age of Jujutsu about 1000 years ago, sorcerers by perfecting their skills were able to defeat him. After his death, they were not able to destroy his body and it passed down generations in the form of cursed objects, represented in a total of 20 fingers[1]. 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 into his body[2]. After his victory against Gojo Satoru, Sukuna is titled as the most powerful character in the work, something admitted by Gojo Satoru himself.

His past appearance describes him as a demon with four arms and two faces. Currently, he looks like his vessel (Yuji Itadori), but with upturned hair in shades similar to pale pink[3] and with lines/marks on his forehead, nose, cheeks and body. He also has a second pair of eyes, below the normal ones. Sukuna also has two lines that begin at his collarbone and descend to his hips, some surrounding his neck and circles on both shoulders[4]. When he takes possession of Itadori's body, he is usually seen wearing the uniform of the Tokyo Metropolitan Magic Technical College. In the manga, he wears a black long-sleeved shirt resembling a gakuran over a red hoodie, black pants[5] and red shoes[6], while in the anime, the shirt and pants are depicted in navy blue color[7]. At other times, he can be seen shirtless, or commonly wearing a light kimono with black trim, a black scarf, and black shoes.[8]

Sukuna has a free spirit that only guides pleasure[9], 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 absolutely refuses to let anyone try to kill him, since doing so would mean getting in the way of his plans [9].

He immediately considers anyone who does not meet his expectations based on strength or physical abilities boring [10]. He constantly criticizes his vessel for how weak and incompetent she is with his abilities, even becoming upset when he loses to an opponent he considers weaker than Itadori [11]. On the other hand, if he encounters someone who is strong and capable of entertaining him enough, he often flatters the skills of his opponent [12].

Although he likes to kill humans, especially weak children [13] and spirited women [14], he possesses a cunning side that he often uses to his advantage. For example, during his confrontation against Megumi Fushiguro, he ripped out the heart of his vessel to prevent him from successfully performing the body switch [15].

Sukuna considers himself above humans, sorcerers, curses, and curse users. His attitude is similar to that of an arrogant tyrant king and, as such, he constantly treats others as his inferiors and orders them around as he feels he has the right to do so. Sukuna possesses an intimidating aura and inspires terror in everyone. He does not hesitate to intimidate and threaten those around him so that they do what he orders. In Shibuya, as soon as he woke up and took control of his vessel body, he threatened Jogo, Mimiko and Nanako to kneel before him. He also threatened all the humans present, saying that if they moved without his permission, he would kill them all without hesitation.
