Kris is the human protagonist of Deltarune, the role-playing game by Toby Fox that began with its first chapter in 2018, and a sword is his signature weapon in its turn-based battles. The brief unsheathing noise comes from those battle moments, where drawing the blade marks the shift from exploration to combat. Fans have clipped the sound for edits, reaction videos and memes because it is instantly recognisable to players and needs no dialogue to land. Its continued use reflects Deltarune's lasting fan community and the way a single game sound can signal readiness.
