This sound comes from Unravel, the first opening theme of the anime Tokyo Ghoul. The song is performed by TK from Ling tosite sigure and became closely associated with the series after the anime aired in 2014. Short cuts of the opening spread through AMVs, anime edits, and reaction videos because the vocal delivery is instantly recognizable and highly emotional. It remains popular years later for dramatic fan edits, especially when creators want a clip that signals angst, conflict, or a major character moment.
