Nineteen years ago, the Dragon Goddess Mynia descended upon the world of Zenith. As punishment for hunting dragons to use their body parts in war, she razed human and demon cities alike.
Now, having recovered from the goddess' attack, war once again brews between the humans and demons.
Caught in the middle are Dain, a man who can transform into a dragon and his magic-wielding companion, Alija. Their job as adventuring mercenaries takes them across the land.
Will they side with the humans, or will Dain be seduced by evil?
