In the continent dominated by the Dragon Knight, countries are peaceful on the surface but undercurrents are surging. Rein Buster, a young man from a family of fallen knights, accidentally formed a contract with the black dragon Tarkes with the broken wing, and was involved in a series of dangerous disputes. The boy and Yuna, the elite of the Knights, join hands in the confrontation to uncover the secrets of the dragon and human worlds. The villain Chris Duram unites with the fallen dragon clan to ignite the continent's strife. Rein, Tarkes and their partners grew up to be real dragon knights through humorous adventures and power struggles. As the truth of the world is gradually revealed, the protagonists must make life and death choices in the battle of ten thousand dragons, fight for friendship, love, and faith, and ultimately save the disintegrated world—or restore it to new life.
