Koyuki Kurosaki is a playable character in Blue Archive, the mobile role playing game first released in 2021, where she is known as a mischievous hacker from Millennium Science School. Her Nihahaha laugh became her signature vocal quirk in dialogue and gacha moments, making it instantly recognisable to players. Clips isolating the laugh spread through YouTube Shorts and TikTok edits, where fans reuse it whenever a character acts smug, gets lucky, or celebrates a pull they were not supposed to get.

Koyuki's signature Nihahaha laugh from Blue Archive, heard when she gets a gacha pull. Creators use it for smug anime wins and mischievous meme moments.
This is Koyuki from Blue Archive delivering her unmistakable Nihahaha laugh, a high pitched giggling burst that lasts just over two seconds. The delivery is bright, smug and a little chaotic, rising quickly as if she has just gotten away with something or pulled exactly what she wanted from the gacha. That mischievous energy is why the clip lands so well in edits, because the laugh alone tells viewers a character is delighted, teasing and probably about to cause trouble for everyone else in the scene.
