The original melody is He's a Pirate, the signature theme from Pirates of the Caribbean: The Curse of the Black Pearl from 2003, composed by Klaus Badelt with Hans Zimmer. Hololive VTuber Minato Aqua, known for her playful singing streams, performed it with the lyrics flipped to She's a Pirate, a nod fans dubbed Pirates of the Caquaribbean. The short clip spread through Hololive fan edits and VTuber compilations. It endures because it merges an instantly recognizable blockbuster theme with Aqua's idol charm, perfect for pirate jokes.
