Dias finally returns home after decades of war.

He's hailed a hero and promptly rewarded with his own domain...which turns out to be little more than empty plains.

Population: zero.

Dias, who has only ever known battle, finds himself at a loss.

How is he supposed to survive, let alone cultivate his territory into a thriving, prosperous dominion when there's nothing but grass as far as he can see?

Fortunately for Dias, a horned girl by the name of Alna is about to show him there's more to the plains than meets the eye!
