KOG Studio is the South Korean game developer behind online action titles such as Elsword and Grand Chase, and its logo sound is the short ident used to introduce the company's name on screen. Logo stings like this are made to be instantly recognisable in only a few seconds, so the clip has found a second life beyond its original videos: editors reuse it as a generic studio-style opener for game content, fan trailers and channel intros. Its short length and clean finish make it easy to drop at the start of a project.
