Sukuna, also known as Ryomen Sukuna, is the fearsome King of Curses and a central antagonist in Jujutsu Kaisen, a manga and anime series that has built a huge global fanbase. Calling such a powerful villain a witch turns his menace into a joke, which is why the line travels well in short-form edits and reaction videos. Creators pair it with dramatic entrances, smug expressions, and plot twists, keeping it alive as a quick, recognisable punchline for anime fans rather than a quote tied to one scene.
