Aldnoah.Zero

Japan has been invaded and conquered by the Britannian Empire. Japan is now known as Area 11 and its citizens known as Elevens. The Britannian Empire takes away Japan's autonomous power and imposes its rule through the use of Knightmares. The Empire's rule has never faltered, but cracks have begun to show...

In the near future, humanity has taken its first steps towards journeying into the far reaches of the galaxy. Upon doing so they discover a huge race of insectoid aliens known as "Space Monsters." These aliens seem dedicated to the eradication of mankind as they near closer and closer to discovering Earth. In response, humanity develops giant fighting robots piloted by hand-picked youth from around the world. Shortly after the discovery of the aliens, Noriko Takaya, the daughter of a famous deceased space captain, enters a training school despite her questionable talents as a pilot. There, she meets her polar opposite, the beautiful and talented Kazumi Amano, and is unexpectedly made to work together with her as they attempt to overcome the trauma of war as well as their own emotions.

Caught in a 150-year-long war, interstellar nations reach the pinnacle of strategic combat at the hands of two genius leaders. Reinhard of the Galactic Empire, and Yang of the Free Planets Alliance lead the charge from opposing fronts. Fighting is their destiny, but in this vast universe torn by political intrigue, their greatest enemy may not be each other.

The year is 2199. The human race has been crushed in their war with the Gamilos, driven into underground cities by the invader's assault. Scientists estimate they have only a year left. The young officers Susumu Kodai and Daisuke Shima receive a mysterious capsule from a ship that made an emergency landing on Mars and return with it to Earth. It contains humanity's last hope: the planet Iscandar on the other side of the Magellan Galaxy has the technology to defeat the Gamilos and restore the planet. The space battleship Yamato is entrusted with this task, but they have only one year before humanity ends.
