Shingeki no Bahamut is a dark fantasy anime franchise set in Mistarcia, a world where humans live alongside gods and demons while the dragon Bahamut remains sealed away. Long ago, that seal was created by splitting the key to Bahamut's prison between rival deities, but the peace it bought is always fragile. As soon as the seal shows signs of weakening, hunters, rulers, and supernatural forces all move to control the future of the realm.
The franchise begins with Genesis, where bounty hunter Favaro Leone and the mysterious girl Amira are pulled into a conflict that could reopen Bahamut's prison. It later continues in Virgin Soul, shifting the focus to Nina Drango and Kaisar Lidfard while the same world of shifting alliances, old grudges, and large-scale battles keeps pulling ordinary people into the center of the struggle. Across both stories, action and adventure are tied to political intrigue and personal loyalties, and every faction must decide how much it is willing to sacrifice to keep catastrophe sealed away.
