Doomsday Armed Mecha

On a festival day in his hometown, the boy was thrown from a bridge into the river. He couldn't swim but accidentally crossed. The technology of the new era allows people to freely modify their bodies, create various bodies with animal characteristics, and even enable space travel. But this is the earth that has been abandoned. Seven hundred years after experiencing the catastrophe, the earth's environment has changed dramatically. Beasts and pollution in the void have occupied people's living space, leaving the remaining humans to live in the safe zone established by the superiors. The sky is blocked, and the earth is full of mutated beasts. Super powers have awakened among humans. Among the ruins of the safe zone, the boy and his armed mecha will bring new changes to the world, break through the prison of the sky, and open the way to the universe.
