After a fierce clash that cost many lives, humanity finally defeats Godzilla—the creature that drove people away from Earth twenty thousand years ago. Yet the beast slain by Haruo Sakaki"s forces was not solitary; another Godzilla lingered on Earth, still undefeated. Severely injured from the first encounter, Sakaki awakens in a young girl"s dwelling who belongs to the Houtua tribe. The Houtua, strikingly human‑like, have evolved to endure the planet"s altered climate long after it was abandoned. Their culture is steeped in myths of resilience, and they have learned to harness the planet"s scarce resources with ingenuity.
With most supplies exhausted, the surviving members of Sakaki"s elite squad wrestle with whether to abandon their mission and planet or face an unlikely fight. Yet hope persists, as the Bilusaludo aliens uncover fragments of their anti‑Godzilla armament, Mechagodzilla. Even armed with this formidable weapon, triumph feels out of reach: Godzilla has spent ages adapting and preparing to crush any challenger. They must choose to retreat or confront the titan, knowing every decision could seal humanity"s fate.
