Ryōmen Sukuna

(宿儺, Sukuna?) is the main antagonist of the manga series Jujutsu Kaisen. Nicknamed the King of Curses (呪いの王, Noroi no Ō?), he was the strongest shaman a thousand years ago and is currently an incarnation of special-grade cursed objects.

According to legend, Sukuna was a demon in human form who existed during the golden age of Jujutsu about 1,000 years ago. Sorcerers, by perfecting their skills, were able to defeat him. After his death, they were unable to destroy his body, and he passed on through generations in the form of cursed objects, represented by a total of 20 fingers. However, years later, during the modern era, Yuji Itadori came into possession of one of these fingers and ingested it in an attempt to help those around him. As a result, Sukuna was able to reincarnate in his body.

After his victory against Gojo Satoru, Sukuna is hailed as the most powerful character in the series, a fact admitted by Gojo Satoru himself.
