Ryomen Sukuna originates from Gege Akutamis Jujutsu Kaisen manga, which began in 2018, and its anime adaptation that premiered in 2020. The fearsome King of Curses became one of anime's most recognisable villains. The wsp version pairs his image and voice style with modern slang for whats up, spreading through TikTok, Discord and soundboards as a short greeting meme. Its popularity comes from the clash between Sukuna's reputation for cruelty and a friendly everyday hello, a joke fans reuse for entrances, edits and reaction clips.
