Unified States

Unified States (合州国) is a democratic state located in the continent to the west of the continent where most of the countries in the series are located in. The nation, though isolationist, is a great power with a vast territory, large population, and immense natural and financial wealth.

It was described by a seaman in the manga as a nation filled with agriculture, oil, and spectacular buildings.

Arkansas, one of its states, is the home-place of Anson Sue's wife.

International Relations

 * Commonwealth (連合王国) -  A special relationship between the two nations exists due to past colonial history. During the Great War, the Commonwealth received both equipment and volunteers from the Unified States and also purchased numerous war materials from US arms companies. Of particular note is the deployment of an aerial mage unit by the Unified States on the behalf of the Commonwealth.
 * Empire (帝国) - The US and Empire were competitors in some industries, but generally had cordial relations as trading partners. During the Great War, the Unified States' public tended to continue their trading relationship, but the government began to become wary of the Empire's military might and is considering hostilities.
 * Russy Federation (anime) (ルーシー連邦)  - The exact relationship the Unified States has with the Federation is not yet clear, but several US armored vehicles are shown being used by the Red Army in Volume 7.
