-Prelude-

Humanity has taken a great step in their attempt to overcome the vast frontiers of the universe. However, as history has written from time and time again, their mental immaturity and unwillingness to acknowledge the benefit of others has forever thwarted them in their attempt to discover the true meaning of their time-limited lives.

The superpower bound for world domination, the Holy Empire of Britannia, defeated Japan, stripped its people of their identity and pride, and renamed it to the colony, Area 11. Hereby, the Holy Britannia Empire actually managed to gain control of nearly two-thirds of the Earth's population.

However, seven years later, on a day when the Japanese people had no hope to speak of, one rebel stood up. A protector of justice, the masked man known as Zero. His tale, and the tale of the people behind him, marked the beginning of how the universe's history was re-written anew.
