Mahjong Soul is an online anime-style mahjong game where players compete in four-player matches and call out moves such as Pon when claiming a discarded tile to complete a set. Ichihime is one of the game's cheerful cat-eared characters, and her short Pon call has become a recognisable audio cue among players and streamers. Short clips of the line circulate in mahjong highlights, fan edits and reaction videos, where it works as shorthand for a confident, well-timed claim rather than just a game sound.
