In a
mystical world where gods, humans, and demons uneasily coexist, the realm of Misstarcia faces absolute destruction. Two thousand years ago, the legendary beast Bahamut threatened to obliterate all creation, forcing the god Zeus and the demon king Satan to unite their powers. They sealed the beast using a magical key split into two halves—one given to the gods, the other to the demons.In the present day, the carefree bounty hunter Favaro Leone spends his days dodging his rival, the relentless former knight Kaiser Loxley, who blames Favaro for his family’s ruin. Their petty rivalry shatters when Favaro stumbles upon Amira, a mysterious, amnesiac woman possessing the god-half of the Bahamut key. Driven by a hollow promise of a wild night, Favaro agrees to help Amira find her mother in the demon capital of Helheim, unknowingly sparking a cataclysmic chain of events.As they journey toward Helheim, pursued by both divine forces led by the ruthless Jeanne d'Arc and demonic factions seeking the key, Amira’s true nature is revealed. She is not merely a traveler, but a homunculus created from an angel and a demon, destined to break the seal and awaken Bahamut by Azazel and the corrupt demon nobles. Concurrently, a shadowy conspiracy within the capital led by the megalomaniacal King Charioce XVII and the sinister necromancer Martinet threatens to upend the delicate political balance.Betrayals fracture the group when Favaro’s past catches up with him, and Kaiser is manipulated by Martinet into a path of vengeance. However, as the demonic forces successfully extract the key from Amira and free Bahamut, past enemies must forge desperate alliances. Azazel, horrified by the true terror of the waking monster, turns against his own kind. Meanwhile, Jeanne is unjustly branded a witch by the
corrupt church, forcing Kaiser to rescue her and rally the human army.The climax explodes into a titanic war at the capital, pitting the combined forces of gods, humans, and rogue demons against the unstoppable, world-destroying wrath of Bahamut. Amira sacrifices herself to weaken the beast from within, breaking Favaro’s heart and forcing the roguish bounty hunter to finally embrace genuine selflessness. Through a combined supreme effort, the heroes reseal the dragon, saving Misstarcia. In the aftermath, Kaiser becomes a leader for humanity, while Favaro mourns the lost Amira, forever changed by a journey that transformed him from a selfish scoundrel into a true hero.
