The year is 2071. Humanity has been pushed to the brink of extinction following the emergence of man-eating monsters called "Aragami" that boast an immunity to conventional weaponry. They ravaged the land, consuming almost everything in their path and leaving nothing in their wake. To combat them, an organization named Fenrir was formed as a last-ditch effort to save humanity through the use of "God Eaters"—special humans infused with Oracle cells, allowing them to wield the God Arc, the only known weapon capable of killing an Aragami. One such God Eater is Lenka Utsugi, a New-Type whose God Arc takes the form of both blade and gun. Now, as one of Fenrir's greatest weapons, Lenka must master his God Arc if he is to fulfill his desire of wiping out the Aragami once and for all. The monsters continue to be born en masse while the remnants of humanity struggle to survive the night. Only God Eaters stand between the Aragami and complete and total annihilation of the human race. [Written by MAL Rewrite]

On the other hand, a certain guard fleet was stationed in the frontier of the galactic system. Though it was the seemingly perfectly ordinary army, the team composed only of the woman called "Angel Corps" existed in this army. They controlled the spaceship which was called "Angel Frame" which was the relic of Lost Technology. And, they collected the lost technology by using the angel frame, and carried out the duties to manage them. They were not the elite pilots, but Angel Corps was rather an eccentric person`s group.
