Synopsis:

The series follows Beryl Gardenant, a seasoned swordsman who has quietly trained generations within his family's dojo in a remote village. His unassuming demeanor belies a skill that has long been recognized by his former students, including Allucia Citrus, now a respected commander in the Royal Order of Knights. Driven by a desire to showcase Beryl’s hidden prowess, Allucia secures him a position as a special instructor for the Order, prompting his relocation to the imperial capital.

There, Beryl encounters a diverse array of former pupils – adventurers, mages, and knights – each navigating their own paths. As rumors of his exceptional abilities spread throughout the capital, he finds himself unexpectedly thrust back into the spotlight. The story explores themes of mentorship, legacy, and the quiet strength found in unassuming individuals, set against a backdrop of established institutions and evolving societal expectations. It presents a character-driven narrative focused on personal growth and the recognition of hidden potential.
