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.

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!
