Kurumi Tokisaki is one of the central characters in Date A Live, the anime series based on the light novels, where her playful yet menacing personality made her laugh instantly recognisable to fans. Clips of the laugh were shared on YouTube and soundboard sites, where editors began using it outside its original scenes for villain edits, reaction videos and cosplay content. It remains popular because the sound carries so much character on its own, instantly suggesting mischief, confidence and a dark sense of humour without needing any dialogue.
