The year is 1999 and the ultimate battle for humanity's future is being fought. It was destiny that brought Kamui back to Tokyo. And what he found waiting for him there surprised him.The Dragons of Heaven, the defenders of Earth, were fighting against the Dragons of the Earth, the seven angels who embrace the thought of Earth's annihilation. Kamui is stuck in the middle. But just who is Kamui?
It has been foretold that Kamui, a mysterious young man with psionic powers, holds the key to the world's fate. Kamui can choose either be the world's savior, or the world's destroyer. After being away for several years, Kamui goes back to Tokyo to rejoin his childhood sweetheart Kotori, and her older brother Fuma. Kamui swears to protect the two no matter what happens. But a strange twist of fate condemns Kamui and Fuma to a destiny of bloodshed... all because Fuma is Kamui's twin star -- existing to play the role opposite of Kamui. If Kamui chooses the side of good, Fuma would automatically belong to the side of evil. If Kamui falls to the evil side, Fuma would be on the good side... which side will Kamui take and what will become of the world's future? And what about Fuma and Kotori? Like that Highlander line says -- "In the end there can only be one...".
