This clip comes from Mahjong Soul, the online anime mahjong game where players compete in riichi mahjong matches using voiced characters. Ichihime, a cat-themed character known for ending lines with a playful nya, announces Kan when a player declares four identical tiles. Fans began clipping short character calls like this one for streams, highlight videos and soundboards, where a fraction of a second of recognisable voice can signal a big play without explanation. Its brevity, clear delivery and feline charm have kept it popular with Mahjong Soul players and anime editors long after its first use.
