Ryomen Sukuna

Ryomen Sukuna, more often called just Sukuna, is a mighty cursed spirit known as the undisputed King of Curses. He serves as one of the primary antagonists of the Jujutsu Kaisen series. According to a legend, during the golden age of jujutsu over 1,000 years ago, Sukuna was an Imaginary Demon, though in truth was a human sorcerer, and other sorcerers gave their all to defeat him. After his death, he became a cursed spirit, and his curse was too strong for his body to be fully destroyed.
