Mobile Suit Gundam Thunderbolt: December Sky

In UC 0093, the Federation has recovered from its defeat and has created a new anti-colonial special forces unit to deal with rebel forces: Londo Bell. Elsewhere in space, Char Aznable reappears out of self-imposed hiding with a declaration that he now commands his own Neo-Zeon movement, and intends to force the emigration of Earth's inhabitants to space by bringing about an apocalypse.

The side story takes place in 2017 a.t.b., between the rise of the “Black Knights” organization and the return of the supposedly "dead" Zero. The setting is in Europe, where the European Union (E.U.) allied nations are being invaded by the overwhelming forces of the Holy Britannian Empire. On the verge of defeat, the E.U. army forms a special unit known as “W-0″, of which a young pilot named Akito Hyuga is a member. Leila Malkal , a former Britannian Aristocrat comes to the E.U.'s aid, commanding the “Wyvern” Knightmare corps comprised of Japanese teenagers. They recklessly plunge into a battlefield, where the survival rate is extremely low, at about 5% only. They fight for their freedom and for a "home" to which they can return.

The war between Euro Britannia and the European Union continues. New orders are given to the W-0 Unit. To land in the middle of the enemy territory as a diversion. The pilots of the W-0 Unit consist only of the commanding officer, Leila, the only surviving Japanese from their last battle, Akito, and the three that escaped from the Eleven ghettos and lived in the underworld, Ryou, Yukiya, and Ayano. With everyone holding their respective expectations, the operation moves forward. On the other side in Euro Britannia, Shin, who made his benefactor commit suicide with the mysterious power of “Geass”, is appointed the leader of the Knights of St. Michael. As Shin steadily advances for the sake of his own ambition, he and his subordinates in the Ashura squad are given orders to deploy. The one that lives in order to fight, and the one that fights in order to live.

In C.E.75, the fighting still continues. There are independence movements, and aggression by Blue Cosmos... In order to calm the situation, a global peace monitoring agency called COMPASS is established, with Lacus as its first president. As members of COMPASS, Kira and his comrades intervene into various regional battles. Then a newly established nation called Foundation proposes a joint operation against a Blue Cosmos stronghold.

The Ark Fleet has been destroyed, and a significant number of the enemy's troops have been wiped out due to its crash landing. As the remaining forces of the Holy Order of Michael regroup in order to launch a final assault on Weiswolf Castle, the wZERO unit, along with their new ally Ashley Ashra, stand ready to intercept them. Meanwhile, with his Geass out of control, Shin moves to erase his younger brother's existence once and for all. But Akito, having promised Leila that he will come back alive, refuses to accept such a fate, and the two clash in their final battle.

Seven years have passed after the battle of Teppelin... Humans have since reclaimed the surface of the earth and enjoy an unprecedented period of peace and prosperity. However, humanity's increasing population growth triggers the sudden emergence of an unknown, powerful enemy. The fearsome, manipulative power of the mysterious Anti-Spiral proves too overwhelming for humans to even fight back. When everyone becomes desperate and loses hope, Team Dai-Gurren members reunite to stand up once again!
