The end of the century is approaching, but is this a new beginning for the earth, or is it the real doomsday? All this is in the hands of the "Sky Dragon" and the "Earth Dragon". The ordinary and indifferent boy, Shilang Shenwei (voiced by Kenichi Suzumura), pulled out the sword sealed in the ground one day. At the same time, he is about to face a difficult choice-to protect the earth and become a "Sky Dragon", or to destroy the earth and become a "Earth Dragon". 14 mysterious men and women gathered on the land of Tokyo. They are the Seven Seals of the Sky Dragon and the Seven Imperial Historians of the Earth Dragon. These 14 men and women with complicated life experiences are going to fight a cruel battle for the earth. Shenwei chose to become a Sky Dragon, and the leader of the Earth Dragon who appeared in front of him turned out to be his childhood friend Momo Fuma (voiced by Junichi Suwabe). Fuma killed his sister Kotori (voiced by Mamiko Noto) in front of Shenwei. From then on, the fate between the two began to flow. The Tianlong was defeated step by step, and finally only the barrier on the Tokyo Tower was still operating. When this barrier was broken, it would be the end of the earth. Can the Kamui, who was predicted to fail, reverse the fate of the earth?
