Ryomen Sukuna comes from Gege Akutami's Jujutsu Kaisen, which began as a manga in 2018 and became an anime in 2020. As the ancient King of Curses trapped inside high schooler Yuji Itadori, Sukuna's rare appearances became instant fan highlights. Short clips of his voice spread through TikTok, YouTube edits and anime soundboards, often grouped with other iconic anime moments like Mangekyo Sharingan activations and Za Warudo time stops. The clip stays popular because one line signals a shift from comedy or calm to genuine danger.
