Kinji Hakari is a third-year student at Tokyo Jujutsu High in Jujutsu Kaisen, and his Idle Death Gamble domain turns combat into a pachinko-style game where a jackpot grants him a surge of power. The domain became a fan favourite during the Culling Game arc, when Hakari's gambling theme, confidence and catchphrase about always betting on himself made him stand out from more serious sorcerers. Online, the sound spread through anime edits and short-form videos that use it to mark lucky breaks, risky bets and unexpected wins, keeping it popular long after its first appearance.
