The greatest nation of humanity—the Empire.
And at the pinnacle of that Empire, its very center, stood the Emperor—a figure who seemed less like a ruler and more like the Empire itself, given human form.
The so-called "strongest" figures of the world were those who had reached the very peak of their respective fields.
The Sword God, the Grand Elder, the Pope… But among them, one stood apart from the rest.
That was the Emperor.
He did not wield a sword with divine skill. He did not devote himself to the service of a god.
Even in the original work, his power was classified as an enigma—an existence so overwhelmingly powerful that even Aswell, the protagonist and the Hero of the story, could not defeat him.
"As if… he were the Demon King of this world."
But that did not mean he was evil like the Demon King of the underworld.
Rather, it was because his authority and power were so absolute, so domineering, that fans of the original work—myself included—would jokingly refer to him as the "Demon King of the human realm."
