A frozen Earth from 10 years ago. An apocalypse survival story on Snowball Earth.
[Snowball Earth Worldview] In the distant future, giant kaiju from space invade Earth. Humanity is on the brink of extinction, and a boy named Tetsuo becomes the savior of mankind, fighting against the monsters alongside the giant robot Yukio. Tetsuo and Yukio engage in a final decisive battle with the kaiju. Afterward, Tetsuo enters a cryogenic sleep, and 10 years pass. When Tetsuo wakes up 10 years later, he is faced with an Earth covered in snow and ice. Human civilization has largely collapsed, and the few survivors are living in restricted spaces. [The Past] 10 years ago, while the savior Tetsuo and Yukio were away from Earth for the final battle against the kaiju, a mysterious giant monster with a human-like form—unlike the typical kaiju—suddenly appeared from the sea at a depth of 10 meters. Along with the monster, a mysterious giant white sphere appeared above its head. As the number of giant spheres increased to one billion, they instantly scattered across the globe. When each sphere expanded to its limit, they exploded, triggering storms of absolute zero. In just 30 minutes, the entire Earth was completely frozen, and it has never been warm since. The survivors gathered in one place and built a small village to live in this frozen world.
