The Heavens hover above Earth, unseen to humanity, a collection of floating island kingdoms maintained by the magic of its godlike residents. This magic can exist thanks to the unknown power source known as Akuto, but it is swiftly running out. Except for the Magical Kingdom, most of the kingdoms in the Heavens agree to utilize the least amount of Akuto necessary to sustain themselves in response to the energy crisis. The Magical King Munto, the ruler of this country, thinks that Akuto can be refilled if he travels to Earth and encounters a mystery female given to him by a seer. While Munto embarks on the perilous voyage, the other kingdoms strive to destroy the Magical Kingdom and seize the remaining Akuto.
