The company describes the story:
From Old Country Bumpkin to Master Swordsman follows middle-aged swordsman Beryl Gardenant, who has only ever accomplished one thing: running a humble sword-fighting dojo in the quiet countryside. But when he’s paid a visit by his former pupil, Allucia, he discovers that she has become an elite commander — and she’s not the only one of his students who’s a renowned warrior. Forced by Allusia to become a special instructor to the strongest order of knights in the kingdom, Beryl must confront whether he’s able to reach his full potential, even as an old man.
Sagazaki launched the story on the Shōsetsuka ni Narō website in November 2020. Square Enix published the novel series’ first volume with illustration by Tetsuhiro Nabeshima in April 2021, and published the ninth volume on March 27.
Kazuki Satō launched the novels’ manga adaptation in Akita Shoten’s Dokodemo Young Champion magazine in August 2021. Yen Press releases the manga in English.
A separate spinoff manga titled Katainaka no Ossan, Kensei ni Naru Gaiden: Ryūsōken no Kiseki debuted in Square Enix’s Young Gangan magazine on February 7, with Sasami Hazama drawing the art, and Zenji Yotsuya credited for composition. The manga follows the character Surena Lysandra in her journey to become a Black Rank adventurer.
The light novel series’ anime adaptation began airing on April 5 on the IMAnimation programming block of 24 TV Asahi affiliate channels, and on BS Asahi. The series streams exclusively on Amazon Prime Video worldwide.
