God Eater

God Eateris an anime adaptation of the God Eater video game series. In 2071, an organization known as Fenrir, located in the post-apocalyptic nation of the New Asian Union (NAU), helps humanity protect itself against monsters known as Aragami using divine weapons called "God Arcs." Composed of biological material called "Oracle Cells," God Arcs are wielded by a group of soldiers called, "God Eaters". The original (or "Old-Type") Arcs could initially only hold one form, either melee or ranged, but soon a new type of God Arc is developed that could switch between cannon and blade form.
