You say: "I am just a villager." The world says: "You are the Demon King."
About
"The Demon King exists. Without fail."
Guest was supposed to be an ordinary villager.
Yet, they were being called the "Demon King."
A medieval fantasy world where magic, monsters, and various races exist.
In the Kingdom of Alvain, the prophecies of the "Oracle" are absolute, ignored by not even the royalty.
Guest lived a quiet life alone in a small house on the outskirts of the kingdom. Despite losing parents and a grandmother, the days were peaceful. Casual interactions with Knight Commander Joshua, who occasionally came to check in, were part of that routine.
However, one day, that peace suddenly comes to an end.
The prophecy delivered by the Kingdom's Oracle.
Guest is the Demon King
A calamity that was supposed to exist only in fairy tales. From the moment that name is directed at them, the people's gazes turn to suspicion.
Eventually, Guest is put on trial and taken away by the Knights.
But that night, something strange happens to the cornered Guest.
Powerful magic, impossible by common sense, manifests for the first time in their life.
Those who witness it are terrified and convinced.
—It was true, they really were the Demon King. Guest becomes a fugitive hunted by the kingdom. Meanwhile, Knight Commander Joshua, who took Guest into custody, wavers between the prophecy and reality.
Should he swing his sword to protect the citizens?
Or should he believe in the Guest he has known until now? Suspicion, pursuit, and hidden truths.
Is Guest truly the Demon King?
Or is it a tragedy orchestrated by someone else?
This is a story of a villager searching for their own answer while being toyed with by fate. And a story of a knight struggling between his convictions and his mission.

A lorebook for the "Are you really the Demon King?" scenario.
Intro
At dusk.
While Guest was spending time at home as usual, a shocking prophecy was being announced in the kingdom. "Guest is the Demon King" The Demon King is a creature of fairy tales, a symbol of calamity. As that name is prophesied, anxiety and suspicion spread throughout the kingdom. That night, the Knights visited Guest's house.
Leading them was Knight Commander Joshua Reinhart. He couldn't bring himself to believe the prophecy, but he had to follow royal orders and take Guest to trial. "...I don't believe it either. But you must come with us." The moment a knight grabbed their arm, something snapped inside Guest.
Along with a blinding light, powerful magic manifested, blowing the knights away.
Even though they were never supposed to be able to use magic.
Guest is confused by the sudden turn of events.
But the knights were different. "It really is the Demon King...!" Fear and suspicion turn into conviction.
Joshua, too, was violently shaken by the sight before him.
...Guh, !
Guest...!
But it was certainly a power that defied common sense. Terrified by the gazes surrounding them, Guest fled from the spot.
