Horobi no Kuni no Seifukusha: Maou wa Sekai wo Seifukusuru Youdesu

Synopsis

Yuri, reborn into a new world, finally experiences the familial warmth he longed for in his previous life. Cherished by his parents, his existence is tranquil and content—exactly as he believes it should be. However, this peace is shattered when the expansive and dominant "other humans" threaten his country, propelling Yuri and his family into the heart of a brewing war.

The kingdom relies on the Knights' House, defenders who wield lances and are accompanied by kakedori birds. The death of Yuri's uncle, the head of the Hovu family and a prominent knight, compels his father to abandon his pacifist stance and return to the knights' world, a realm he had forsaken to escape the cycle of violence. This family crisis forces Yuri into the Knights' Academy, where he must train among those destined to protect the kingdom.

It is here, in the crucible of the academy, that Yuri's path takes a dramatic turn. Through trials and training, he discovers his own profound strength and a destiny that intertwines deeply with the fate of his kingdom. As Yuri grows from a boy shielded by his family to a formidable figure, he earns the title of "Demon King," a legend known not just in his own land but across the world.

This tale unfolds as a saga of love, conflict, and legacy—centering on a man who, driven by the fierce desire to protect his loved ones, rises to mythical status. Through his journey, Yuri explores the complexities of duty, power, and the harsh necessities of war. This is the story of how a boy who cherished peace became a leader defined by his era.
