Ryomen Sukuna is the King of Curses and the main antagonist of Jujutsu Kaisen, the manga by Gege Akutami that became a hugely popular anime series from 2020. Known for his overwhelming power and cruel confidence, Sukuna quickly became one of the most quoted anime villains online. Short clips of his voice are widely shared in fan edits, TikTok videos and gaming montages, where his calm threat adds instant drama. The welcome line works because it needs no context: even viewers who have not seen the series recognise the tone of a powerful villain arriving.
