World War III

World War III (第三次世界大戦, Dai san-ji sekai taisen) was a large international war being fought throughout the Tenchikaimei series.

Prologue
Twenty years before the beginning of the series, the United States of America elected a more militaristic and blood-thirsty President. With his sheer mental prowess and ruthlessness, the newly elected president manipulated the American system until, two years into his term, he was finally able to establish a monarchy in the nation that had for centuries been a free Republic. It soon became clear to the nations of the world, that this new President wasn't just content with America's current borders.

Shortly after his take over of the country, the President launched a full scale invasion of both Mexico and Canada. The war was over within weeks, and the two once sovereign nations were absorbed into the new American Empire. The brutality of these acts ignited discussions within the United Nations about how best to deal with the increased threat of the Empire, and the now-Emperor that ruled it.

The United Nations mustered an army together to fight against the Empire and its ruler, but even with this, there were nations that feared the Empire's power, and so sided with it, becoming part of the Empire itself. Thus began World War III, the largest military engagement since the last World War.
