The clip is identified as the KOG Studio logo sound, the short audio ident used by the South Korean game developer behind Elsword and Grand Chase. Studio logos like this are designed to be instantly recognisable in a few seconds, which is why short idents travel well beyond their original games and end up on soundboards. Online, creators reuse it less as a game reference and more as a generic studio bumper, lending a polished, official feel to fan videos, edits and parodies even when the content that follows is deliberately informal.
