Place it in the middle of a boss-fight edit, after the challenger appears and before the outcome, then follow it with a shocked reaction for the defeat and Why Are You Running for the chase that follows.
このサウンドについて
This is a 17-second cut of Megalovania, the driving piano-led theme from Deltarune, built on rapid notes and heavy drums. It feels tense and electrifying, like the moment a final boss steps forward and the fight suddenly matters. The track is the game's instantly recognisable battle music, made for turning an ordinary scene into a showdown.
