My Infinite Monster Clones

The apocalypse arrives. Twenty-one spatial gates open, linking Earth to beast-star planets larger than the sun.

Endless alien beasts.

A battlefield of civilizations.

Who opened the gates?

This is the story of alien beasts invading Earth from the beast stars, only to get thoroughly beaten.

It is also the story of a protagonist leading humanity in its fight for supremacy across the boundless starry skies.
