"Yukio, I'm going to make friends."

Ten years have passed since their final decisive battle for the survival of humanity, but upon returning to Earth, all they found was a land covered in snow and ice. Amidst the changed landscape of this Snowball Earth, Tetsuo sets out to find the remnants of humanity in this unknown world, with his promise to Yukio still resonating in his heart.
