The manga adaptation (by Shiki Shiraishi) is published by Futabasha on "Gaugau Monster."

The novel version is from Shueisha Dash X Bunko, with illustrations by 100yen Locker.

Thornmarx, now 13, and affectionately known as "Soma," has been granted admission to the Royal School, a knight training academy he has long yearned to attend. At the entrance ceremony, students' God-given "Abilities" (their innate talents) and skill levels are assessed, leading to class placements.

"White Knights" (White): For nobles, also attended by royalty.

"Blue Dragons" (Blue): Merit-based.

"Scarlet Blades" (Scarlet): Centered around girls.

"Yellow Lances" (Yellow): For beautiful boys and girls.

"Emerald Shields" (Emerald): Unflashy but reliable.

"Black Steel" (Black): For those who don't fit anywhere—in other words, problem children.

These six classes are available.

Actually, Soma possesses memories of a previous life, having lived in a country called "Japan." Soma has a rare ability called "Trial and Error," which allows him to see skill levels numerically, and he has been tirelessly raising them. The top-tier "Blue Dragons" class, open even to commoners with sufficient ability, is guaranteed for those with a total skill level exceeding "200." Soma, to be absolutely sure, had raised his level to an astonishing "1,012."

This year, the Royal School was buzzing. With Lagenberg, one of the three great ducal houses, leading the pack with a skill level over "300," and ten students scoring in the "200s," it was a year of exceptional talent. They were already being whispered about as the "Generation of Glory." Then came Soma's turn for evaluation.

"Next, the top student in the academic exam, Thornmarx-Leck—"

That was Soma's miscalculation. The assessment machine, it turned out, was not designed to recognize four-digit levels. Due to his excessively high levels, Soma was misjudged and consequently thrown into the problem-child class, "Black Steel."

But Soma is not one to be deterred by this. Armed with his inherent "Trial and Error" ability, he steadily begins to transform the aristocratic-centric mindset of the academy—.
