Yandere Simulator is an indie stealth game in development since 2014, created by YandereDev. Players control Ayano Aishi, a schoolgirl who eliminates rivals competing for her crush's attention by stealth, sabotage or direct action. Clips of rival eliminations spread widely through YouTube let's plays, fan edits and TikTok reposts, helping short in-game cues become recognisable outside the game itself. This kill sound is now reused by fans as shorthand for a successful elimination, even in videos that have nothing to do with the original school setting.
