Rage of Bahamut: Genesis

Beelzebub declares the war between demons and gods over with Bahamut's awakening as he is its master, and commands the gods to bow before him. He then orders the great dragon to unleash its power to which it attacks Beelzebub before proceeding to blast everything in sight. Rita manages to save Kaisar and reveals that Lavalley is really, Gilles de Rais, a sorcerer with a bounty who is the one behind Bahamut's revival as well as all the deception. The demons and gods team up to fight against the uncontrollable Bahamut. Kaisar attempts to attack Lavalley only to find they have no effect before Lavalley reveals he is Martient as well. Elsewhere a heavily wounded Beelzebub curses Martient's deception of using Amira to be able control Bahamut before Azazel finishes him off, ending his revenge. A bloody Favaro appears, revealing he's not dead and begins combat against Kaisar seemingly by Lavalley's command. Favaro gains the upper hand before proceeding to cut Kaisar's hand off, presenting it with the bounty armband to Lavalley. Favaro catches Lavalley off guard by warning him about having a bounty on his head before Kaidar recites the bounty armband's incantation thus turning Lavalley into a bounty tablet. As Rita tends to Kaisar's wounds Favaro reveals that Kaisar managed to shoot him with the antidote, turning him back to normal and the fight was an act. As Bahamut continues to rage Favaro declares it's up to him to stop it and he'll kill Amira as it's the only way to stop the beast as well free her from sadness. Kaisar decides to join Favaro to save Amira, still believing there is a chance to separate her from Bahamut. In order keep Bahamut still for a minute the demons and gods work together to contain the beast to allow Favaro and Kaisar to approach it. With tears in his eyes Favaro screams Amira's name as he stabs Bahamut, unleashing a beam of light. Amira then appears before him, chiding him for being late and he promises to take her somewhere better than Helheim. Amira proceeds to kiss Favaro after realizing he isn't lying when he meets her with a serious, sincere gaze. She thanks Favaro before disappearing back inside Bahamut, causing the beast to explode though Kaisar escapes, leaving Favaro to be caught up in the blast that destroys his leg. Half a year later in the royal capital Kaisar, given a mechanical hand from Rita, commands the soldiers as a lieutenant with his knighthood intact. Favaro is alive with a mechanical right leg and is back to bounty hunting though he remarks Bahamut will never be forever gone. Kaisar then suddenly appears, forsaking his knightly duties, swearing not to be in Favaro's debt and the two ride off.

Rita escapes from the castle after being confronted by a suspicious cloaked man who threatens to dispose of her. Meanwhile the King proceeds with Jeanne D'Arc's death sentence for deceit and conspiracy carried out before a crowd of protesters who proclaim her innocence. As Jeanne burns she faces fiery visions of the gods forsaking her, including her patron angel, causing her to accept the words of the cloaked demon. Jeanne is converted from a saint into a witch by the demon and she escapes the capital by wielding a fierce and dark power as she is now a demon. Meanwhile Favaro thinks over the dragon's words of killing Amira as the trio continues their journey to find Amira's mother. They are intercepted by the cloaked man who is the same demon who tricked the king as well as Jeanne; Amira reveals him to be her mentor Martinet who in turn tells them they are in Helheim. Rita seeks out Bacchus and inquires about Martinet but the two run into a severely injured Azazel. The demon lord Beelzebub appears before the trio, capturing Kaisar and Favaro, telling Amira to fulfill her purpose before showing her mother. Martinet reveals in actually Beezlebub recreated Amira from Nicole as an imitation vessel and he is her "true" birth parent as all Amira's memories are fabricated since as she is a mere tool to release Bahamut. Amira's compromised emotional state causes the key's seal to unlock, falling into the demon's hands as the completed Transcendent Key. Azazel agrees to help Rita if she takes him to Abos while Favaro pretends to join the demons but Martient sees through the plan and forcibly makes Favaro a demon.

Amira stumbles upon the statue of Bahamut, triggering a vision of the beast being freed. Meanwhile The angels discuss Jeanne being worthy of becoming a Holy Knight to defeat an awakened Bahamut, later granting her another holy weapon: a sword. Amira tells the others about when she first woke up from a long slumber and was given her necklace by an unknown figure, promising to fulfill her dream in Helheim. The King then calls the group before him and Amira points out her father to Favaro and the others, Jeanne D'Arc's lieutenant Lavalley. The King knights Favaro and Kaisar which Favaro begrudgingly accepts while Kaisar is ecstatic to have his honor restored. Elsewhere an injured Azazel confronts Beelzebub for scheming behind their leader Lucifer's back and as Beelzebub incinerates Azazel he reveals he's bringing about Judgement Day. The jealous King is tricked into thinking Jeanne is plotting his death after she is favored by the gods and not him. That night Favaro and Rita take Amira to see her father, Lavalley. Lavalley reveals Amira is half angel and half demon, her mother being the angel Nicole and that he is not her father but a human former bodyguard to her mother. When Amira was a baby the demons kidnapped her and accelerated her growth, Amira really being 5 years old. When Amira says she was promised to see her mother in Helheim if she stole the key Lavalley tells her that is impossible and uses the united pendents to reveal Nicole's true location: Prudisia, the Valley of the Demons.

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

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