The final fight for humanity's future is fought towards the end of the millennium. Shirou Kamui's fate is sealed when he returns to Tokyo to face his ultimate test. The Dragons of Heaven, Earth's protectors, stand ready to safeguard the earth from the Dragons of Earth, the seven angels of mythology who embrace the planet's devastation in order to purify it. Now Kamui must choose which side to fight for, despite the fact that the concept is completely repulsive to him. It is not until Kamui realizes that his two boyhood friends, Monou Fuuma and Monou Kotori, are in grave danger that he resolves to take on his fated role in the Year of Destiny: 1999.
