Code Geass: Lelouch of the Rebellion

The year is 2307 A.D. Although fossil fuels have been depleted, humanity has obtained a new source of energy to replace them, in the form of a large-scale solar power generation system based on three huge orbital elevators. However, the benefits of this system are available only to a handful of major powers and their allies. In this world of never-ending conflict, a private armed organization appears, dedicated to the elimination of war through armed force. Its name is Celestial Being, and it is in possession of "Gundam" mobile suits.

What would you do if you suddenly found yourself in the middle of a war? Teenager Amuro Ray sees his life shattered when war comes to his home. During the chaos, Amuro finds himself inside the mobile suit Gundam, the Earth Federation's new secret weapon, and he somehow gets it to work. Amuro and the other refugees flee their homeland on the warship White Base. This group of children and inexperienced soldiers will change the outcome of the war.

When a young laborer escapes to the world aboveground, he discovers a violent land in which humans battle robots controlled by a power-hungry noble.
