Sixteen-year-old Jun dreams of proving his worth as a warrior in the elite Guardian's Tournament, held every six years to entrust the magical Scroll of Heaven to a new protector. Eager to prove his skills, Jun hopes that a win will restore his father's pride - righting a horrible mistake that caused their banishment from his home, mother, and twin brother. But Jun's father strictly forbids him from participating.
He believes there is no future in Jun honing his skills as a warrior, especially considering Jun is not breathmarked, born with a patch of dragon scales and blessed with special abilities like his twin. Determined to be the next Guardian, Jun stows away in the wagon of Chang and his daughter, Ren, performers on their way to the capital where the tournament will take place. As Jun competes, he quickly realizes he may be fighting for not just a better life, but the fate of the country itself and the very survival of everyone he cares about.
