Ryoumin 0-Nin Start no Henkyou Ryoushu-sama

After decades of brutal warfare, the decorated soldier Dias returns home, expecting a hero's reward. He is granted a lordship over his own domain, but the reality is a cruel joke: a vast, empty frontier with zero inhabitants. A man who knows only battle, Dias now faces his greatest challenge: building a prosperous territory from absolute nothing.

His journey of creation begins with a fateful encounter with Alna, a mysterious horned girl who reveals the hidden potential within the untamed plains. This anime chronicles the heartwarming and arduous process of nation-building, exploring themes of found family, resilience, and finding purpose beyond the battlefield.
