Codegease: Air-ground Warfare 1946

(This is a fanfiction of *Codegease: Lelouch of the Rebellion* titled *Codegease: The Night Before the Cold Sky 1945*.) After years of struggle, the anti-fascist alliance was finally close to defeating Nazi Germany. To save themselves, the Germans devised an incredible plan: using a mysterious machine still in the experimental stage, hoping to open a door to another world and request their aid. They thus forever changed the world. However, this did nothing to help Nazi Germany; they were still utterly defeated and ultimately surrendered unconditionally. But this change led to the rise of a new power: the Britannian Empire, led by Emperor Charles, who firmly believed that conquering the world was their destiny. The empire launched an attack without any warning. Fortunately, we were not entirely unaware of their existence. The Northern Alliance and the Eastern Alliance regrouped their armies, set off again, and brought back victory.
