At the millennial edge, the concluding battle for humanity's future is staged. Kamui Shirou's destiny has been decided as he returns to Tokyo to face his ultimate challenge. The Dragon of Heaven, defenders of the Earth, stand ready to protect the world from the Dragon of Earth, the seven angels of legend, who embrace the devastation of the planet to bring about its purification. Now Kamui must decide which side to fight for although he finds the idea utterly unappealing. It isn't until realizing that his two childhood friends, Fuma and Kotori Monou, are in grievous peril that Kamui decides to step into his fated position in the climactic struggle of the Year of Destiny: 1999.

Takaya Ougi is just a typical high school guy who wants nothing more than to protect his best friend and live a normal life. Enter Nobutsuna Naoe, an older man who informs Takaya that he is in fact the reincarnation of Lord Kagetora. Naoe, himself a possessor, awakens Takaya's abilities to exorcise evil spirits and fight the Fuedal Underworld. While most possessors remember their former lives before being reincarnated, Takaya does not. Naoe is thankful for this, considering his passionate and abusive past with his Lord Kagetora. As Takaya improves his abilities, he also begins to remember what Naoe did because of his love for him. Meanwhile the dark forces of the Hojo and Fuma clans begin their attack as the Fuedal Underworld descends upon the living world.

Takaya was sent to Kyoto to investigate the re-awakening of Ikko sect and Araki Murashige, a member of the Ikko sect who deserted the clan.With the help of his vassal Haruie, Takaya is finally successful in tracing Araki who hunts down a 400-years-old mandala (Buddhist artifact for meditating) that was made of the hair of the deceased Araki clansmen. Unfortunately, by the time they meet, Haruie recognizes Araki as Shintarou, her lover in her past-life. Takaya orders her to eliminate Araki, who is a threat, but will she be able to do it. Furthermore Takaya finally meets Naoe...
