Unravel was released in 2014 as the opening theme for Tokyo Ghoul, performed by TK from Ling tosite sigure, and quickly became one of the most recognisable anime songs online. Its quiet, aching verses and explosive chorus made full versions and acoustic covers hugely popular with fans. Short excerpts later spread on video platforms as a meme shorthand for heartbreak, inner conflict and dramatic character arcs, often paired with slow zooms, rain and monochrome filters to mimic the show's dark, emotional tone in edits and parodies.
