Space princess Fandora and her sidekick Que are bounty hunters in an age where warp travel has become a reality, along with space criminals. Fandora possesses the red, magic, Jewel of Lupia which she uses to fight with when conventional weapons are ineffective. In pursuit of space criminal Red Eye Geran, they encounter in the kingdom of Lemia a mysterious evil religious leader who has taken control from its legitimate rulers. This individual possesses a blue jewel which will unify the dimensions of the universe and start an age of peace or terror if it is conjoined with the Jewel of Lupia. And so Fandora and he are fated to meet.

Above Earth, invisible to humans, float the Heavens—a collection of floating island kingdoms supported by the magic of their godlike inhabitants. The mysterious power source known as Akuto enables this magic to exist, but this is quickly running out. In response to this energy crisis, most of the kingdoms in the Heavens agree to use the minimum amount of Akuto required to sustain themselves, except for the Magical Kingdom. The leader of this kingdom, the Magical King Munto, believes that Akuto can be replenished if he travels to Earth and meets a mysterious girl shown to him by a seer. While Munto sets off on the dangerous journey, the other kingdoms attempt to destroy the Magical Kingdom and acquire the remaining Akuto for themselves. On Earth, Yumemi Hidaka is dealing with her own problems. She can see floating islands in the sky that nobody else can. While her best friend Ichiko Ono believes her, Yumemi wonders if she is going insane. When Munto suddenly appears before her, Yumemi dismisses him as a mere delusion. She is more concerned about her 13-year-old friend Suzume Imamura, who is attempting to elope with her delinquent boyfriend. As the Magical Kingdom nears the point where it will fall from the sky, Munto's quest to save both the Heavens and Earth grows increasingly desperate.

Six long months have passed. The Raalgon Empire has developed a horrible new type of weapon, and Tylor has been charged with the duty of intercepting it as it is being transported. But when all that could go wrong does go wrong, the crew members of the Soyokaze find themselves at the mercy of their enemies. As the hours tick down toward their execution, the crew wonders: has their irresponsible captain misled them? Or is this all a part of some greater strategy? (Source: RightStuf)
