Dragon's Breath

Sixteen-year-old Jun strives to prove his worth as a warrior and become the next Keeper of the magical scroll of the Heavens. To do this, he must win the elite Guardians tournament, held once every six years.
Jun hopes that victory will restore his father's honor and rectify the mistake that led to their exile from home, separating him from his mother and twin brother. However, his father is fiercely against Jun's participation in the tournament, as the young man lacks the breath mark and he does not see a future warrior in him.

Despite his father's ban, Jun sets off for the capital to participate in the tournament. Soon he realizes that his struggle involves not only his personal life but also the fate of the entire country and the survival of his loved ones.
