Synopsis
In a world called Mistarcia, where gods, demons, and humans coexist, a fearsome dragon named Bahamut was sealed away long ago by the combined efforts of gods and demons. The key to Bahamut's prison was split in two to prevent its release.
The story centers around Favaro Leone, a carefree bounty hunter who finds himself entangled in a much larger conflict when he encounters Amira, a woman who possesses one half of the key to Bahamut's seal.
Favaro, along with other unlikely characters, must navigate a dangerous world on the brink of chaos as the balance between gods and demons threatens to shatter, potentially unleashing Bahamut once more. They are forced to forge their own destinies as they become central figures in a potentially world-ending clash.
