The origin of Naoya 9 is not clearly documented in the information available for this clip, so it is best understood through how it circulates online. On soundboards, short numbered clips spread because they are easy to find, replay, and reuse in edits. Their appeal is practical: a brief, recognisable tag that creators can attach to reactions, jokes, and transitions without needing a long setup. That reusability keeps it circulating among meme editors and short-form creators.
