Ten years ago, humans, gods, and demons joined forces to fight against the threat of the colossal dragon, Bahamut. The creature was sealed again, but not killed. Now, in the present, humans living in the capital city of Anatae, with the help of a new crowned king, have reached unimaginable heights. Charioce XVII not only enslaved demons and destroyed their capital, but he also weakened gods, because of some unknown technology that he had obtained. Bahamut is still alive, humans, demons and gods are not allies anymore, and the revival of Bahamut is still very likely. Will they forget about the old resentments and bring an end to Bahamut once and for all?
