Kidou Senshi Gundam Thunderbolt: December Sky

In the ruined Thunderbolt Sector of U.C. 0079, the Earth Federation's Moore Brotherhood and Zeon's Living Dead Division fight through the wreckage of Side 4. Federation pilot Io Fleming, a reckless jazz lover, receives the heavily armed Full Armor Gundam and sets his sights on the enemy snipers controlling the sector.

Among them is Daryl Lorenz, a skilled Zeon pilot who has already lost his legs to the war. To counter Io's growing threat, Daryl is pushed toward an experimental system that demands even more of his body. Their rivalry becomes a brutal duel between two soldiers being consumed in different ways by the same war.
