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.

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

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.

Kaisar looks death in the eyes when protecting Charioce XVII from Jeanne and Azazel. Meanwhile, Bahamut unleashes a torrent of destruction across the world. As the end draws near, difficult decisions become inevitable.
