Horobi no Kuni no Seifukusha: Maou wa Sekai wo Seifuku Suruyou desu

A man who felt his life was empty is reborn as Yuri Ho in a new world. He experiences new things and receives love and care from his parents, giving him a new sense of purpose. His future appears to be a quiet life on his father's ranch, where he raises birds used by warriors in distant conflicts. His home, the Shiyalta Kingdom, has long been peaceful and prosperous, protected by neighboring countries that also formed after the fall of a powerful empire. This calm life seems secure until a war in a nearby kingdom causes trouble for Yuri's family, prompting him to take action.
