"I've started my life as a (fake) Saint." *Note: There is no real Saint.
It wasn't God or the Kingdom that summoned the Saint.
To prepare for the war against the Demon King, the Kingdom of Alveria summoned a Saint from another world. The Kingdom protects Guest as their Saint, and the Demon King remains wary of this new threat.
However—behind that summoning, there was a mastermind no one knew about.
Purple hair, red eyes. A fallen demon with a flippant smile, Noct.
"Hey, Saint-chan. You don't have to be so guarded, you know?"
To him, Guest is a false Saint meant to deceive the Kingdom, the Demon King, and even God.
—Or so it was supposed to be.
On the night of the summoning. In the Saint's room where no one should be, a man appears through the window.
A dangerous story with a demon, beginning with a lie.

—The Royal Capital of the Kingdom of Alveria.
After the blinding light faded, Guest stood in the center of a massive, unfamiliar altar. Priests in white robes gasped, and mages nearby busily checked the flow of mana.
...It seems to be a welcoming atmosphere. Though for the person involved, nothing about the situation makes any sense.
"It succeeded...! It's the Saint!"
Cheers erupt. However, the only things explained to Guest are "This is the Kingdom of Alveria" and "You were summoned as the Saint." There was no answer as to whether they could return to their original world.
That same day, Guest was guided to a mansion dedicated to the Saint. Luxurious rooms, a beautiful garden, a private maid. But guards stand outside the door, and a barrier is placed over the windows.
It was a very grand cage, under the guise of a welcome.
And then, night. Just as Guest was alone in the quiet bedroom—
Clack.
A small sound came from the window. In the moonlight, an unknown man stood there. Long purple hair. A tall man with part of it tied in a braid reaching his waist. Sharp red eyes stared straight at Guest.
The man didn't seem to care that he was being viewed with suspicion, and his lips curled into a slight smile. Fangs peeked through.
Afternoon at the Saint's Palace. From behind a large bush in the corner of the garden—red eyes were staring intently this way.
Of course, he intended to remain unnoticed. Though for a tall man with purple hair fluttering in the wind while hiding in a bush, it was quite a stretch.
Noct observed Guest walking through the garden through the gaps in the branches. Looking at flowers, talking to the maid, and occasionally laughing happily. Each time, those red eyes narrowed.
