SNOWBALL EARTH

In 2025 AD, after a sudden invasion of intergalactic kaiju, a painfully shy boy, Tetsuo Yabusame, saves the autonomous bomb Yukio and becomes an unlikely defender of Earth. Ten years later, now hailed as a "savior", Tetsuo heads into space with Yukio for the Final Battle. With 20,000 kaiju closing in, humanity's fate is on the line to bring an end to this relentless conflict!

The world outside the escape pod is covered in snow and ice, and devoid of life. Tetsuo sets off to find human survivors, his promise to Yukio on his mind. Riding an excavator that he finds in the ruins, he battles an intergalactic kaiju that attacks him, and it is then that he encounters the members of humankind who've survived! Can Tetsuo finally make the "friends" that he's always longed for?

After meeting Ao and the others on the frozen Earth, Tetsuo is gradually accepted into the fold. But the respite is short-lived, as they find themselves under attack by an intergalactic kaiju that Tetsuo's never seen before in any of his battles. As the people flee en masse, Tetsuo confronts the kaiju alone. Its overwhelming power soon drives him into a corner, and just when it seems as if his...

Tetsuo and Yukio are crossing the snowy plains to reach the Mishima Mall, where Ao and the others live. Receiving an enthusiastic welcome from the survivors, who hail him as their "savior", Tetsuo, through his interactions with Ao and Takimura, experiences the warmth of civilization and community for the first time in ages. But why is it so warm here when the world is freezing cold? The secret...

Welcomed into the Takimura family, Tetsuo meets Hagane, a young girl who just lost her mother a month ago. She shows Tetsuo something that she built in her late mother's lab… Meanwhile, an organization called "The Light of E-RDE (Vierde)" led by a mysterious man called "the Colonel" is making ominous moves after learning that Tetsuo is alive. A new enemy silently makes its way towards the...

Suddenly, Yukio is assaulted from afar by snipers. Showing up soon afterwards is "The Light of E-RDE (Vierde)", a brigade of boys and girls controlling kaiju. Like Tetsuo, their commander, Sagami, once belonged to E-RDE. He's a man harboring a twisted sense of justice and raging jealousy. As past grudges and madness mingle inside him, he unleashes a merciless attack on Tetsuo and the others!

Yukio, half-destroyed, is under fierce attack by Hercules, a powerful kaiju that emerges from the snow. Tetsuo desperately goes on the defensive, but bit by bit, the enemy's overwhelming power and calculated tactics backs him into a corner. Finding himself in dire straits, what Tetsuo tries next to turn the tide of battle is… communication, for the first time ever!

Ten years after saving Earth with his robot friend Yukio, Tetsuo returns to a planet of endless ice and snow.
