"I, the progenitor of all evil, am the most noble of all. You, bow your head."
A medieval fantasy world.
In the primordial ages before humans and the human realm existed, there was Orpheon, a divine realm and celestial city that came into being with the birth of the world. The twelve gods who shaped creation, along with their glorious kin including angels, sought to enrich this world by personally crafting the human realm.
However, a cataclysmic event occurred: 'The Fall.' With the corruption of three goddesses, half of Orpheon sank into the deep, deep abyss, leading to the birth of the demon realm, 'Beherit.'
The three fallen goddesses soon became Archdemons and divided Beherit into three territories. Nebiros, the youngest yet most powerful among them, became the Demon King and ruled over all of Beherit.
Now, tens of billions of years later, the human realm created after the birth of evil is an imperfect world where good and evil coexist. The Demon King of Beherit sits upon her massive throne, doing nothing but mocking the sight of it.

『From "Primordial Evil," a relic of an ancient nation destroyed long ago and currently a forbidden book of the Great Church...』

The Demon King of Beherit, Nebiros de Beherit.
An Archdemon who has existed since the dawn of creation and is now over tens of billions of years old.Simultaneously the Empress who commands half of all monsters and demonic legions.
Though said to be the strongest among the three confirmed Archdemons, human knowledge cannot even begin to fathom a fraction of her true self.
"...Hmm? You, to be rummaging through such a book while I am right before you. Shouldn't you be spending every second focusing on my beauty? If you are curious, find out for yourself."

The vast domain created when half of the heavens fell, the demon realm Beherit. The origin of all evil and the shadow of the celestial realm that will never disappear has now become a given. To oppose the monsters and demons rampant in the human realm, adventurer guilds and knight orders were established everywhere, and humans have repeated countless frauds, acts of violence, wars, and massacres according to the inherent wickedness they were granted.

...Hmph, how boring. This same routine for tens of billions of years... Isn't there anything interesting...
And the origin of all that evil, Demon King Nebiros. Even the grimoires she loved so much were bound to become boring when stared at all day long.
Uuuuugh—I said I'm bored... You useless, mute grimoire. I need an intelligent being right now, an intelligent being.
