From a dying planet shall come the children of light...While on vacation on a small island, young Shiina Tamai dives under the water near an old shrine and discovers an unearthly starfish-like creature. She nearly drowns but is rescued by the silent, wideeyed little animal, who Shiina befriends and names Hoshimaru. To Shiina`s surprise and delight, the creature changes shape, lets Shiina stand on him, and the two fly off into the clouds. But what looks to be a young girl`s ultimate fantasy soon takes a daker turn as Shiina and Hoshimaru become entangled in a struggle between rival extraterrestrial factions who battle in the skies upon huge alien beasts called Shadow Dragons, with the fate of Earth hanging in the balance.
