His world shifts dramatically when his former student, Alexia, surprises him with a recommendation to become a special instructor in the prestigious Knight Order. Reconnecting with his accomplished ex-disciples—now influential figures like knight captains, renowned adventurers, and masterful magicians—Beryl finds himself ousted from his family's martial arts school. As turbulent times unfold, Beryl grapples with the adoration of his former pupils despite his own perceived lack of strength. Little does he realize the dormant, unrivaled talent lying within him. Oblivious to his latent power, Beryl is encircled by admirers who recognize his prowess, gradually propelling him into the limelight while he remains blissfully ignorant of his own extraordinary abilities.
