As humanity faces extinction from the insatiable Aragami, monstrous beings that resist conventional weaponry, their only salvation lies in Oracle Cell weapons made of the same material as the creatures. Despite the Aragami's adaptive prowess, rendering them immune to most attacks, a decisive plan emerges: detonating a nuclear reactor to eradicate the Eurasian threat. Tasked with this perilous mission are three elite fighters known as 'God Eaters' from the Fenrir Far East Branch, armed with the formidable God Arcs. With these advanced weapons designed to pierce the Aragami's defenses and obliterate their cores, these warriors stand as the final hope for humanity's survival against the relentless menace.
