Favaro Leone travels the land, collecting bounties while avoiding a rival bounty hunter. But his life changes when he encounters a mysterious girl from the sky.
After receiving a helpful tip from Bacchus, Favaro and Amira finally board a boat headed for Helheim. By sheer coincidence, its captain is an old friend of Favaro's father.
Favaro and Amira escape from the royal capital, and all sides - gods, demons, and humans - are thrown into confusion. Meanwhile, the king of Anatae begins to act very oddly.
