The sound comes from The Mimic, the Roblox horror experience built around Japanese folklore and chapter based scares, where Kaito is one of the threatening figures players encounter. Clips of its jumpscares spread through Roblox edits, TikTok and YouTube Shorts because the audio works even without the visuals. Fans often pair it with the FNAF jumpscare scream in compilations, and it sits in the same Roblox sound culture that made the ROBLOX oof so recognisable, though this one is used purely for fear and shock comedy.
