Asuka and Maya are typical high-school students living in Tokyo. Even though their parents were archaeologists, they lived a rather mundane life. But then one day, the same ominous dream that the two siblings were having lately suddenly became a reality. The seven monsters that sunk down the land of Atlantis and destroyed most of the ancient civilizations 10,000 years ago has suddenly revived. Modern weapons were no use against the strange weapons of Atlantis. The entire world was engulfed in the flames of war and it did not take long for the hands of evil to reach Japan. Asuka and Maya’s parents, who were caught in an attack, revealed the truth to their children during their dying moment – they were not Asuka and Maya’s true parents. During an archaeological trip on a deserted island 17 years ago, the couple discovered an Aurawing, an aircraft built by the ancient Mu civilization. Inside the aircraft there was a life-support system containing a pair of infants. Indeed, Asuka and Maya were actually the children of a brave warrior from Mu who fought against Atlantis 10,000 years ago. Asuka and Maya, now awakened to their true destiny, are the only hope mankind has against Atlantis. The siblings board on their respective Aurawing ships, each possessing a mystical power, as they fly off to a continent shrouded in dark clouds.
