Tetsuo is gradually being accepted by Aoi and the others he met on the frozen Earth. However, his peace is short lived when he is attacked by a Galactic Kaiju that looks unlike anything he has fought before. While everyone else flees at once, Tetsuo stands alone to face the monster. He falls into a dire situation in the face of its overwhelming power, but at the moment of his absolute crisis, someone appears!

Introduction

"Yukio, I’m going to make a friend."

For shy young Tetsuo,
the only friend he’s ever known is the giant robot Yukio.
Together, they defended humanity as its “saviors,”
standing against galactic monsters that invaded from space.

A decade has passed since their final,
desperate battle for humanity’s survival.

When Tetsuo finally returns to Earth,
he finds a world transformed into a frozen wasteland—
an icebound planet now known as Snowball Earth.

Carrying the promise he once made to Yukio deep in his heart,
Tetsuo takes his first steps into this strange new world.
