On the sword-and-magic continent of Kunaaan, the demon dragon Daganzord menaces three uneasy kingdoms. As a child, Hiiro lost his parents when a ritual to seal the dragon ended in the disaster remembered as the Balbagoa Tragedy; rescued by the swordsman Giruu, he trains for years to take revenge. Years later, Hiiro sets out to hunt Daganzord, joined by Giruu and the cat-eared information broker Erin as their party crosses the continent.
