Oshi no Ko began as a Japanese manga by Aka Akasaka and Mengo Yokoyari, before its anime adaptation brought its story of idols, fame and hidden ambition to a wider audience in 2023. The series quickly became a talking point among anime fans, and short clips from it spread through edits, reaction videos and social posts. This five-second sound is used in that same way, as a compact, instantly recognisable cue for idol-themed edits and dramatic anime moments, keeping the series present in online fan culture long after its episodes aired.
