Apocalypse Machines in Another World

A weapon born in the apocalypse, built to ensure victory, vanished just when humanity needed it most.

Humanity was wiped out...

But in another plane of existence, deep within the boundless universe, a cold war machine appeared out of nowhere.

Yet this world had no savage monsters or apocalyptic horrors. Its people didn't worship technology, but instead pursued strength of their own, and most importantly, this world didn't need him to save it.

Having lost his purpose, he decided to live quietly here.

But it seemed he had forgotten: he was a machine born for battle. There was no such thing as peace. He would never age or die, and every moment was spent preparing for combat!
