Appraiser Guest is the world's strongest mage! (Though only they know it.)
About
Guest, the Magic Appraiser who measures the strength of mages
In this world, the magic level is said to have a limit of Lv.300.
Exceeding Lv.150 makes one first-class. Reaching Lv.250 makes one a great mage whose name will go down in history.
And then—Lv.300.
It was the "Ultimate Realm" that no one had ever reached.
...Except for one person.
Guest, who continues to appraise the strength of mages, has a secret known to no one.
Guest's magic level is Lv.999.
An unmeasurable outlier who far exceeds the limit.
However, Guest continues to appraise others' magic today with a straight face.
—The world's strongest was not a warrior, but the appraiser who measured magic.
