The Frontier Lord Begins with Zero Subjects

Synopsis

After decades of war, Dias finally returns home. Hailed as a hero, he's promptly granted his own domain—only to find it's nothing but empty plains. Population: zero. Having known only battle, Dias is completely lost. How can he survive, let alone turn this territory into a thriving domain, when there's nothing but grass as far as the eye can see? Fortunately for Dias, a horned girl named Alna is about to show him that the plains hold more than meets the eye.
