This clip is identified in its audio metadata as a slash and impact effect from Deltarune Chapter 3. The chapter was released in 2025 as part of Toby Fox’s episodic role-playing game. Online, the sound is commonly labeled with the name “Swoon,” making it easier for players and editors to distinguish it from the game’s other combat-style effects. Its clear two-part structure has helped it remain useful in gameplay videos, fan edits, animations, and reaction clips that need a rapid strike followed by a strong visual payoff.
