The clip comes from Lucky Star, the 2007 slice-of-life anime following the gaming-obsessed Konata Izumi, whose habit of mimicking everyday sounds became a running joke among fans. Her playful take on the Windows XP chime captures a double nostalgia: the early-2000s PC era and the anime boom of the same years. Passed around in anime meme circles and Discord soundboards, it sits comfortably beside other retro system audio like the Windows XP Error sound, still used today as a tiny in-joke that only fellow fans immediately get.
