From Old Country Bumpkin to Master Swordsman: My Hotshot Disciples Are All Grown Up Now, and They Won't Leave Me Alone Volume 4

Following the hectic royal escort mission, Beryl settles back into his quiet life with Mui. Unfortunately, his peace is shattered by yet another unannounced visit from Lucy, and this time, the ace wizard Ficelle is with her. Beryl learns that Ficelle has become the instructor of sword magic at the institute, but there’s just one problem—she’s a terrible teacher! When Lucy asks Beryl to help with the class, he is bewildered. How can he possibly teach young wizards when he’s just an old backwater swordsman with no magical talent? Still, he agrees to sit in on Ficelle’s class, and what he observes is just as bad as advertised. Can Beryl help his former pupil learn to teach pupils of her own? After all, sword magic can’t be that different from the swordplay he taught at the dojo...right?!
