Place it at the very end of a mahjong win sequence, after the tile click and the reaction shot, as the final payoff. Pair it with Click Nice for the tile placement just before it, then follow it with Okay Let's Go to carry the celebration into the next round.
About this sound
This under-a-second clip is Ichihime's bright, playful voice line from Mahjong Soul, announcing a tsumo win with a cheerful cat-like 'nya' at the end. It feels triumphant and cute at once, like a tiny victory fanfare for a lucky draw. The line comes from the anime-style mahjong game Mahjong Soul, where Ichihime is one of its characters.
