Taming Beasts in a Ruined World

Luciel awakens in a parallel world ravaged by apocalypse—a land of desolation where crops no longer grow, the rain burns like acid, and the sky is forever shrouded in dust.

On the brink of death, he is saved by a mutant rabbit-eared girl, and at the same time, he awakens a mysterious Trainer System.

From that moment on, everything changes.

A tiny tortoise evolves step by step into a sacred beast, its back vast as ten thousand miles, bearing mountains, rivers, and fertile soil—luciel's future homeland.

A fragile sapling grows into a towering World Tree, shielding against acid rain, calming storms, and restoring blue skies and white clouds.

A single military ant becomes the progenitor of an unstoppable Ant Legion, a living sandstorm that leaves only bones in its wake.

Even the rabbit-eared girl who rescued him… somehow gets tangled up in his fate.

With each creature tamed, Luciel reshapes the wasteland.

From surviving in ruins to creating a new paradise—this is the journey of a man, his beasts, and a system that knows no limits.
