The exact source of this short Japanese line is not widely documented online, so it circulates mainly as a standalone soundboard clip rather than as a clip tied to one famous scene. Anime fans and editors reuse it because the phrase is instantly recognisable even without context, and its meaning, that an enemy remains, works across many stories and games. Shared through soundboards and short video edits, it has stayed useful as a quick dramatic cue, especially for creators who want tension without explaining a full scene.
