Invulnerable to conventional damage, only "Oracle Cell" weapons—composed of the same matter which makes up Aragami—can kill these creatures. However, due to their god-like ability to adapt, the Aragami soon develop further immunity. Having no other hope of fending off the enemy, the remnants of human governments decide to detonate a nuclear reactor and wipe out the monsters facing Eurasia. The soldiers tasked with this mission are aided by three "God Eaters" dispatched from the Fenrir Far East Branch, an organization controlling what remains of Japan.
