Ryomen Sukuna (両りょう面めん宿すく儺な, Ryōmen Sukuna?), more often referred to as simply Sukuna (宿すく儺な, Sukuna?), is the strongest jujutsu sorcerer from a thousand years ago. Regarded as the undisputed King of Curses (呪のろいの王おう, Noroi no Ō?), Sukuna is one of the primary antagonists of the Jujutsu Kaisen series. Sukuna was incarnated in June 2018 when Yuji Itadori consumed one of his fingers.
