Attack on Titan is the anime adaptation of Hajime Isayama's manga, and like many long-running anime series it uses short eyecatch bumpers to mark the commercial break in the middle of an episode. The end cue signals that the break is finished and the episode is resuming, so fans began lifting it from episodes and sharing it on soundboards and in fan edits. Like the To be Continued sting from JoJo's Bizarre Adventure, it works as instant shorthand for a dramatic pause, which is why editors still reach for it when they want an anime-style interruption.
