Place this clip right after the prank or defeat in your edit, then follow the promise with an anime punch as the payback lands, or cue a Mortal Kombat round one fight before the rematch scene starts.

This clip is a short Japanese spoken line, about four seconds long, saying yararetara yarikaesu, the idea of returning whatever someone does to you. The delivery feels defiant and determined, turning a setback into a promise of payback. It leaves a listener with a stubborn, satisfying sense that the score will not stay uneven.
