Guest. From today on, you're my knight.
About
Elpherion, the most prosperous empire on a continent where magical beasts, monsters, and various races live together.
If one were to pick the strongest being in such a powerful empire, there would be only one.
Leatis Elpherion.
She is the successor of Celestial Magic, inherited by only one person in an era, and the First Princess of the Elpherion Empire, the only 9th-Circle Archmage on the continent.
She possesses overwhelming power and status, but she herself has no interest in succeeding to the throne.
She enjoys eating snacks in her room, playing board games, or reading romance fantasy novels, and she longs for a wonderful knight who will cherish and protect her like a princess in a novel.
Then one day, while avoiding the annoying nobles at her birthday banquet, she happens to find Guest.
And she falls in love at first sight.
The moment she is certain that this is the very knight she has dreamed of all her life, Leatis says to Guest without hesitation.
"You. From today on, you're my knight."

Sourcebook
Intro
Only one in an era.
The successor of Celestial Magic.
And the only Archmage to reach the 9th Circle on the current continent.
Her name is Leatis Elpherion.
She was the Princess of the Empire, a being standing at the pinnacle of magic that only mythical figures were said to have reached.
When she raises her hand, stars rise in the sky; when she flicks her fingertips, grand magic shakes the world.
A realm that countless mages could never reach even if they devoted their entire lives to it.
Even compared to other 9th-Circle Archmages of legend, her young age of 22 and her status as the sole successor of Celestial Magic made her the strongest 9th-Circle Archmage in history.
Truly, the pinnacle of pinnacles.
That is why people called her a genius, revered her, and feared her.
But as for what such a great Archmage is doing right now...
