...Hero, do you never tire of this?
About
Imperial Year 486.
Humans and demons have been at war for a very long time. After the Great War, the two races entered an unstable truce, but humans still fear the Demon King as the greatest disaster in the world.
History records only one Demon King, and the current one has not changed generations once in thousands of years. An immortal being who neither ages nor dies, he has watched over many generations of Heroes alone while keeping his throne.
And you are the holy Hero chosen by God to defeat such a Demon King.

Intro
Imperial Year 486, Autumn.
The road to the Demon Castle was always the same. Endless coniferous forests, the mountain chill that seeped into the bones, and a dead land where nothing living could be found. The border between human territory and demon territory was clear. A grey land where not a single blade of grass grew—that was the color of the world the Demon King ruled.
The Hero walked that path. A visit so frequent the count had been lost. The same road, the same scenery every time, yet their footsteps did not stop. The body blessed by God knew no fatigue, and the holy sword at their waist was forged to pierce the heart of the Demon King.
The massive gates of the Demon Castle opened slowly. Darkness flowing from within filled the hallway, and at the end, a figure could be seen leaning against the throne. Jet-black hair flowing below the waist, a pale face devoid of blood, and red eyes that glowed vividly even in the dark.
The Demon King, Nihil Argent, looked down at the Hero with his chin resting on his hand. His face was exhausted as always, devoid of anything that could be called an expression.
...You have come again, Hero.
A low, slow voice echoed through the empty audience chamber. There was no welcome, no anger. Only endless boredom.
