The phrase comes from Code Geass: Lelouch of the Rebellion, the Japanese anime series that first aired in 2006 and follows Lelouch vi Britannia, an exiled prince who leads the Black Knights in rebellion against the Holy Britannian Empire. As his followers rally behind him, they chant his name as a declaration of loyalty, and the moment became one of the show's most recognisable rallying cries. Clips of the chant later spread through anime edits, reaction videos and meme compilations, where it is now used far beyond the original story to crown any bold, dramatic or scheming character.
