Ryomen Sukuna comes from Jujutsu Kaisen, the manga by Gege Akutami that began in 2018 and was adapted into an anime by MAPPA in 2020. Sukuna is the King of Curses, an ancient and feared antagonist whose fingers are powerful cursed objects and whose presence inside Yuji Itadori drives much of the story. Clips tied to the character spread widely through anime fandom, edits and meme soundboards as the series grew, and short Sukuna audio is now reused far outside full scenes as a quick signal of dominance, danger and villain energy.
