Kyota and his pals Shingo and Junichi dream of becoming pop idols. At a New Year's show they get their lucky break when a Cosmopop agent discovers the trio and offers to manage their debut. Then things take a turn for the weird when Kyota begins having visions of magical girls battling one another in the air - only he's not dreaming! For centuries, five supernatural factions have waged war for supremacy over mankind with legend prophesizing that one day the Aquarian Age will begin and one group will reign supreme.
