GOD EATER - 01

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 was developed to switch between cannon and blade form.
