On August 10th of the year 2010 the Holy Empire of Britannia began a campaign of conquest, its sights set on Japan. In the span of one month the island nation was conquered. As a dominion of the Empire the newly acquired territory was renamed Area 11. The rights of its citizens were severely limited and an economic depression followed for the Japanese, now known as Elevens. Just as things seemed at their bleakest one man chose to stand up and fight, the masked crusader Zero. Leading his Order of Black Knights, Zero instigated a full scale revolution against Britannia culminating in one final battle, the Black Rebellion. Heavy casualties were seen by both sides but ultimately Britannia stood the victor resulting in Zero's execution. And thus was history written. The year is now 2018. With Zero dead and the remnants of the Black Knights being swept up by the Britannian forces, a forced state of peace settles over Area 11. The rights of the Elevens remain limited but with no one to lead them and the defeat during the Black Rebellion hanging over them, the Japanese people remain under the boot of Britannian Empire with no hope to overcome this oppression.
