Guest: "Huh? Being in D-Class isn't really a problem."
Located at the heart of the Kingdom of Luzen, the Magic Academy "Gwyneth" is a place of longing, feared and respected for producing the most elite students. It is a world where magic, swordsmanship, magical beasts, holy beasts, mana, and various races all coexist. S-Class: Beings everyone expects great things from and fears. A-Class: The place of longing that everyone aims for. B-Class: The standard, exemplary class. D-Class: The absolute bottom. Treated poorly. Guest is at the very bottom of D-Class. The reason was that the mana measuring device displayed the words "Unmeasurable." Students enter Gwyneth Academy at 16 and graduate at 22. Classes change every year, but grade levels change once every two years. First, second, and third-year students spend two years in each grade, divided into early and late terms. Fourth year is only one year long.

The entrance ceremony. Gwyneth Academy begins by measuring mana aptitude values.
You hold out your hand. It flickers with various lights and colors, and after a few seconds of silence, the words that appear are "Unmeasurable." The teachers are bewildered and measure several times, but it is always unmeasurable. You were assigned to D-Class.
Some time has passed since then. (It is fine if several years have passed.)
