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.

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…

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.

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.

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

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.

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

There are rumors of a mysterious rag demon that has been massacring humans in the capital. Hearing this, Nina decides to try to catch this wanted criminal. Nina is a young girl who has come to the capital to work hard and earn money to send back to her mother in her rural village.

After waking up in Rita's clinic, Nina continues to work hard in the capital. Azazel approaches her in hopes of using her red dragon powers to get revenge against the humans.Meanwhile in the palace, Charioce XVII questions Kaisar on his responsibility for failing to capture the rag demon, spurring Kaisar to attempt to contact the rag demon on his own.

A god has infiltrated the capital following the trail of Mugaro's recently unleashed power. Nina is enjoying life in the capital as if nothing happened, and she has a chance meeting with an attractive, young man. Back at the palace, Charioce XVII takes up command and sets out to capture the rag demon (Azazel) himself.

The rag demon (Azazel) faces Charioce XVII's forces alone in order to save the demons that are being held hostage.

After Azazel was saved by Nina, and he now wants to use Nina in his revolt against mankind. Being completely unaware of all this, Nina is enjoying shopping with Mugaro in the city. At the same time, Kaisar and Rita are having lunch together...

Nina is out shopping for supplies to prepare for the evening festival of the war commemoration. She bumps into the handsomely disguised Charioce in the city once again, and invites him to the food stand she is helping to run.

The Orleans Knights captain Kaisar becomes uneasy as he spots demons led by Azezel acting suspiciously, so Kaisar attempts to advise Charioce XVII against participating in the upcoming victory parade. Meanwhile, Nina has no idea that any of this is going on as she helps run the food stand with Rita in the city.

Burning with rage, the demon Azazel engages King Charoice XVII in combat, and the Orleans Knight captain Kaisar takes action to do what he believes is right.

Even while she's imprisoned, Nina is still her energetic self, working away tirelessly. On the other side of the prison, Kaisar finds out that his old friend Favaro has also been imprisoned and discovers that Favaro already knows Nina. Kaisar sits and listens as Favaro tells him the story of how he met Nina.

Captain of the Orleans Knights, Jeanne D'Arc, is ejected from the capita following differences with Charioce XVII, which costs her everything.

Hoping to see Mugaro again, Jeanne and Nina decide to break out of the prison where they're being imprisoned. In the capital, the gods have　gotten hold of El's power, and they demand that Charioce return the power that he took from them.

After failing to break out of the dungeon once, Nina and Jeanne are helped by Rita in their second escape attempt. Meanwhile, Gabriel leads the gods' advance on the royal capital, where Charioce is waiting. Forces on each side are about to open fire.

War erupts between humans and gods. To get the upper hand against the fast-advancing gods, Charioce XVII activates a weapon that was slumbering deep underground. Just when Nina and the others are escaping from the dungeon, they're thrown into the heat of battle.
