Katon is the fire-release style of ninjutsu in Naruto, the long-running anime and manga series centred on young ninja, and its techniques are often announced with a shouted jutsu name before a burst of flame. Clips of those fiery attacks became popular material for fan edits, reaction videos and soundboards, where the short, punchy sound works even for viewers who have never watched the series. It remains widely used because fire techniques are visually and aurally dramatic, instantly signalling power, danger and a decisive moment in a fight.
