The Frontier Lord Starting with Zero Subjects ~Dias of the Blue and the Horned Maiden~

Driven by his parents' dying wish to aid others, Dias spent years battling on the front lines, eventually earning the revered title of "Savior Hero" for his wartime exploits. As a reward for his service, the king granted him a vast territory. However, upon arriving at his new domain, Dias discovers that he has been given the short end of the stick: a remote frontier land with absolutely no inhabitants. His new life takes an unexpected turn when he encounters Aruna, a horned Kijin girl who resides in the desolate region. Together, they embark on a journey to build a thriving community from scratch. Despite the harsh realities of ruling an empty borderland, Dias embraces a slower, more deliberate pace of life, determined to cultivate his territory and protect its first resident while navigating the challenges of lordship.
