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. 2071年、極東――此処は荒ぶる神々の領域。 2050年代初頭、突如出現した未知の生命体「オラクル細胞」は、 地球上のあらゆる対象を「捕喰」し始めた。 全てを喰らい、凶暴な生命体として多様に分化を遂げるその存在を、 いつしか人は、畏怖を持って「アラガミ」と呼んだ。 既存の兵器はアラガミの前に一切効果が無く、 都市文明は崩壊し、人類は徐々に生息圏を奪われていった。 そんな人類に一筋の光明がさす。 オラクル細胞を埋め込んだ生体兵器「神機」が開発され、 それを操る特殊部隊、通称「ゴッドイーター」が編成された。 荒ぶる神々に虐げられた世界で、「神を喰らうモノ」の明日なき戦いの幕があがる―。
