The Heroic Tale of the "Classless" — Banished by a Duke's Family, He Discovers He Can Steal Skills with His Fists and Becomes the Continent's Greatest Hero (WN)

“Let me land one punch—then I'll turn the tables!”

At age 18, Reit becomes “unemployed” during the “class division” and is disowned by his Holy Knight father, banished from the city.

But he possesses the power to “master an enemy's skills just by striking them”—

Thanks to this ability, he masters both magic and swordsmanship, joins the Knights, and rapidly rises to become a Grand Knight.

　
Meanwhile, the Wellsley family who exiled Reito sends his half-brother Kite to the knight order as their successor, plotting one scheme after another. Yet they fail repeatedly and fall into ruin.
