Black Rover is a song by Japanese singer-songwriter Vickeblanka that became an opening theme for the anime Black Clover, which follows Asta, a boy born without magic who dreams of becoming the Wizard King. Its energetic rock sound matched the series' underdog story, and fans began clipping the opening for AMVs, TikTok edits and gaming montages. The chorus is instantly recognisable to anime fans, so the short excerpt still works as shorthand for determination, rivalry and a hero refusing to quit.
