Ryomen Sukuna is the King of Curses in Jujutsu Kaisen, the manga and anime series where powerful sorcerers use domain expansion techniques to trap opponents inside a space shaped by their own cursed energy. Sukuna's domain, Malevolent Shrine, is presented as one of the most feared in the series, which is why its associated sound became a shorthand for unstoppable power in fan edits. As anime clips spread on TikTok and YouTube Shorts, creators began using the cue for reveals, boss entrances and exaggerated power moments, and it remains popular because it needs no explanation for fans.
