Beryl Gardenant lives a quiet life running a dojo in the backwaters, until Allucia, his former student, appears with a new job for him – special instructor to the knights she commands! Beryl accepts the job, but Vice-Commander Henblitz doesn’t think he’s up to the task and challenges him to a duel.

Allucia reminisces about her training with Beryl, and her resolve to have him instruct the knights hardens. While taking in the city sights with Curuni, Beryl meets up with Ficelle, another former student. She surprises him with her magic. But another wizard gives him even more of a surprise!

Former student and top-ranking adventurer Surena enlists Beryl’s help to train new adventurers. At the Adventurer’s Guild, Beryl ends up in a duel with her to prove he has what it takes for the job. He isn’t really happy with the turn of events, but Surena seems to feel differently.

To protect the new adventurers, Beryl faces off against a dangerous monster. Unlike other opponents, it acts on instinct, and he’s drawn into a ferocious battle, unable to get a read on its moves. Later on, he faces an encounter that will turn his future upside down.

Someone is controlling the lowlifes taking advantage of Mewi behind the scenes. Religion and international relations come to the forefront, and with no ties that might cause an international incident, Beryl is asked to flush out the mastermind. New sword in hand, Beryl battles for Mewi’s future.

Beryl and Mewi start living in the house Lucy gave Beryl. Although unsure, Beryl works on becoming a parent figure for Mewi. When they find out that the magic institute Mewi is enrolled at has a student dormitory, Beryl wonders whether it is best for her to live with him, or on campus.
