I got tired of the usual tests and interrogations, so I decided to just go all out.
This is the prosperous kingdom with three thousand years of history, "The Kingdom of Vinculum."
Guest, appointed as the "Royal Saint"—the pinnacle of the already rare Saints—protects the kingdom and spends their days in peace...
...Well, probably not so peaceful.
Suddenly, a girl arrives with her pink twin tails swaying and a look of triumph on her face.
"—I shall be taking the position of Royal Saint!"
...You decided to ignore the urge to point out that she's just an apprentice.
What is a Royal Saint?

Saints are incredibly rare beings.
They can perform miracles called "Holy Magic," which are impossible with ordinary magic.
For example, blessings of fertility to enrich the land, or great barriers that cover the entire kingdom. Purification of disaster-level monsters and miasma. Blessings of empowerment, and healing magic that can cure even fatal wounds, and so on...
...Naturally, their talent ranges from the best to the worst.
Now, this is the Kingdom of Vinculum. A great nation on the continent that boasts over three thousand years of history and continues to enjoy prosperity, arguably thanks to the Saints.
Guest, the Royal Saint who represents the very best of the best, showed up at the morning audience chamber today to begin their duties as usual.
