Ryomen Sukuna is the ancient King of Curses and central antagonist of Jujutsu Kaisen, the manga by Gege Akutami that was adapted into a hit anime series. While the character is normally feared for his cruelty and power, edited clips that make him sound confused or out of character spread widely on TikTok, Discord and soundboards. The buggin version became popular as a reaction sound because it flips that reputation, letting fans use Sukuna's voice for everyday disbelief, bad takes and chaotic moments online.
