RahXephon

The city of Tokyo has been overthrown, taken over by the Mu, invaders who have devastated the rest of the planet. Within the domed walls of the city, however, time flows in a different path, and none of the citizens even know they've been conquered. Outside Tokyo, the remnants of the human race have fought a desperate 15-year war against the Mu, knowing only that the key to victory lies within the occupied city. But no one has been able to get into Tokyo”until Ayato Kamina, a young resident fleeing a horrifying attack on the city, unwittingly breaks out. An extraordinary mystery unfolds as Ayato confronts a world he has never known, and begins to learn the horrifying secrets of RahXephon, a humanoid super weapon which apparently only he can control.
