Infinity Castle is strongly associated with Demon Slayer, where the shifting castle space became a memorable visual for fans. Online, short clips labeled as the Infinity Castle opening or Infinity Castle door spread through anime edits, TikTok-style transitions and dramatic meme videos. Its popularity comes from how quickly it signals danger, mystery and a scene change in barely more than a second. Creators often treat it like a stylized transition effect, similar to a teleport sound, especially when cutting between worlds, characters or power-up moments.
