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

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.

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.

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 Charioce XVII is leading Bahamut to the capital, demonic forces jointly commanded by Azazel and Lucifer besiege the city. Jeanne's rebel army enters the fray, which results in a free-for-all battle of men, gods, and demons. Amidst the chaos, Dias finds Alessand wandering the battlefield.

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…

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

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.

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

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

Nina and Jeanne leave behind the battlefield and head toward Nina's home in search of a way to enter the land of the gods. There they meet the village elder and are warmly welcomed by the villagers, including Nina's mother.

Jeanne and Sofiel leave the land of the gods in search of El, but they aren't able to get any information. As part of a plan to snatch Charioce XVII's bracelet, Nina and Alessand lead an effort to sneak into a ball at the palace.

By meeting Charioce XVII again, Nina gains the ability to transform into a red dragon at will. Azazel has escaped the coliseum and is filled with bitterness when learning of Nina's new ability. El gazes on at Azazel, and the group plans how to snatch the bracelet that Charioce is wearing.

Charioce XVII brings unrest to the land of Eibos, where Bahamut was revived a decade ago. Nina follows the king to Eibos in order to put an end to his violent acts. Having lost her son El to a stabbing, Jeanne leads her allies to make an assault on the capital and slay Charioce.

Nina and Jeanne soar through a storm to reach the land of the gods. Once there, Jeanne is reunited with her son, El. Meanwhile Azazel now a captive of the humans is forced to battle other demons to the death in the capital's coliseu.

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.

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...

Rita frantically attempts to save El after he's stabbed by Alessand. El's mother Jeanne is powerless to do anything but watch. Azazel makes his ire known and then vanishes into the rain. Alessand pleads with the head of the Onyx Knights to allow him entry into the force as a reward for stabbing El.

Nina and El flee from the land of the gods and return to the capital. There they are reunited with Rita and Favaro, who have rescued Kaisar. While searching around town for information, Nina once again encounters Charioce XVII in disguise.

After fleeing from Charioce XVII's ball, Nina and the others are pursued by the Onyx Knights, who make an attempt on their lives. Mugaro acts together with Azazel, and Jeanne encourages him to return to the land of the gods.

El attempts to evade Nina and Bacchus in order to flee from captivity in the palace of the gods. Meanwhile, in the capital of Anatae, Kaisar is taken from prison to the coliseum, where he's forced to battle one-on-one against a demon.
