以为是CLAMP大神们的时尚大剧，单是主要角色便有14个之多，岂料随着2000的来临，世界末日不见了，X也中止了

In 1999, a teenager named Kamui Shirō returns to Tokyo after a six-year absence. He comes to protect those dearest to him, Kotori and Fūma Monou, and fulfill his mother's dying wish of changing fate. The end of the world is fast approaching as superhuman individuals gather and take sides in Tokyo, the battle site of Armageddon. Following Kamui's arrival the Dragons of Heaven and the Dragons of Earth, the two factions in the final battle for humanity's future, vie for the young man's allegiance, convinced his power will assure their victory. The Dragons of Heaven are the first to contact Kamui. The Dragons of Heaven are guided by Hinoto, dreamgazer for the Legislature of Japan. They are the protectors of the kekkai, spiritual barriers (in the form of buildings such as the Tokyo Tower) that hold the fabric of nature together. As long as the kekkai survive, Judgment Day is postponed. The Dragons of Earth are the counterpart to the Dragons of Heaven. Their mission is to destroy the kekkai and unleash earthquakes so the Earth can be cured of the plague of humanity. They were assembled by Hinoto's sister Kanoe, secretary to the Governor of Tokyo.
As Kamui is forced to choose between the two sides, he concludes he only wants to protect Kotori and Fūma, and becomes a Dragon of Heaven. At the same time, Fūma has a change of personality and becomes the "Kamui" of the Dragons of Earth as he was destined to be Kamui's opposite. Fūma kills Kotori and swears to kill Kamui. Deciding he wishes to bring Fūma back to normal, Kamui joins the Dragons of Heaven in their fight against the Dragons of Earth. Because of the issues regarding the manga's serialization, the plot from the series has yet to be concluded by Clamp.
The animated films and the TV series follow the manga's initial story and come to two different endings. In the film all the Dragons of Heaven and Earth die in the ensuing battles, leaving Kamui and Fūma as the last Dragons. In the final battle, Kamui decapitates Fūma and the film ends with Kamui crying why he ended killing his best friend. In the TV series, all the Dragons of Heavens lose their powers to create kekkai because of they lose their most important people leaving the Tokyo defenseless. As Hinoto commits suicide to stop her alternate self from attacking the Dragons of Heaven, Kamui goes to face Fūma. In the fight's outcome, Kamui is killed by Fūma, but uses his last forces to transform his body into a kekkai that protects the world from the change from the Dragons of Earth, and causes Fūma to return to his old self.
