Ryomen Sukuna is the primary antagonist of Jujutsu Kaisen, the manga by Gege Akutami that began in 2018 and the MAPPA anime adaptation that premiered in 2020. Known as the King of Curses, his arrogant one-liners became a staple of anime meme culture, with short voice clips circulating on soundboards, TikTok edits and gaming montages. Fans use his cold greetings to signal overwhelming power or mock confidence. The character's popularity has kept these brief voice lines in steady circulation years after their first appearances.
