Ryomen Sukuna is the King of Curses from Jujutsu Kaisen, the manga by Gege Akutami that began in 2018 and the anime adaptation that followed in 2020. The character became one of modern anime's most quoted villains for his arrogant, dismissive way of speaking to anyone weaker than him. This Portuguese version of his insult circulated widely among Brazilian fans on short video platforms and soundboards, where short threatening lines are reused as reactions far beyond the original scene and fandom edits.
