Favaro tries everything possible to remove his newly-acquired demon tail. Meanwhile, an elite band of knights is sent to retrieve Amira's God Key.

While humans, gods, and demons pursue the God Key, Amira and Favaro venture into a small town covered in a mysterious, eerie fog...

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 Rita try to find a way into Azazel's flying castle, where Amira and Kaisar are being held prisoner.

Favaro, Amira, and the others are captured and taken to the royal city of Anatae. There, truths are revealed and executions are prepared…

Azazel, leading a demon horde, launches an assault on the human castle. His aim: Amira and the God Key.

Azazel has been forced to retreat, and now the truth behind Amira's existence is revealed. Favaro and Kaisar are summoned to see the king, however...

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.

All hell breaks loose when Amira is finally reunited with her mother.

The humans and angels struggle in a last-ditch effort to keep Amira from unlocking Bahamut's seal.

Bahamut has been released, and the world is faced with destruction. How can anyone stop the power of this legendary beast?!
