Kidou Senshi Gundam 00

2307 AD.
As fossil fuels became exhausted, humanity found a new energy source to change their situation: A large-scale solar power system with three enormous orbiting elevators. However, only a few large countries and their allies reaped the benefits.
Three superpowers had ownership of the three orbiting elevators: The Union, based in the United States Of America, The People's Reform League, made up of China, Russia, and India, and Europe's AEU. The superpowers continue playing a large zero-sum game for their own dignity and respective prosperity. Even though it is the 24th century, humanity has yet to become one.
In this world where war has no end, a private militia appears advocating the eradication of war through force. Each possessing a mobile suit Gundam, they are Celestial Being. The armed intervention by the Gundams against all acts of war begins.
