Ayumi Hamasaki

Ayumi Hamasaki recorded the main theme for Dragonball Evolution, "Rule/Sparkle," bringing her pop sensibilities to the live-action film's soundtrack. Akira Toriyama, the creator of Dragon Ball, illustrated Hamasaki wearing Goku's gi for the single's artwork, creating a unique collaboration between the music industry and the franchise's original artist.

Hamasaki stands as one of Japan's most successful musicians, with her first album selling over fifty million copies and establishing her as a pop icon throughout Asia. Beyond music, she works as a songwriter, record producer, model, lyricist, and actress, making the Dragonball Evolution collaboration a natural intersection of her multimedia presence.
