Recap

Cain reports to the king about his training under Yuuya and presents a katana entrusted to him by Yuuya. Eric then informs Cain about a notice from the adventurer’s guild, reminding him to complete a mandatory quest to retain his A-rank status. Tasked with subduing ten bandits on the route from Gracia to the royal capital, Cain flies over the forest and discovers the bandits attacking a carriage carrying Parma’s father, Sabinos, guarded by Millie and Nina. Cain heals a wounded Nina and defeats the bandits, escorting them back to the capital. There, Nina and Millie are astonished to learn Cain is both an A-rank adventurer and a baron. While submitting Sabinos’s testimony, Cain encounters Crosse flirting with Millie and Nina, who flees upon seeing Claude. Claude reveals that Millie is his younger sister and learns about her past connection to Cain as his tutor. After Cain promises to craft a magic bag for Lina, Claude questions why he still attends school despite his numerous accomplishments. After Cain goes home to prepare for school the next day, Claude, Lina, Millie, and Nina take on a quest of becoming substitute teachers for the adventuring class at the royal academy in an attempt to help Cain become more popular at school.

At school, Cain’s homeroom teacher, Elka, instructs the class to practice magic on targets but forbids Cain from participating due to the overwhelming power of his spells, as even beginner-level magic threatens the school’s barriers. During adventuring class, A-rankers Claude and Lina and B-rankers Millie and Nina are introduced as special instructors. When asked to display his gold guild card, Cain resists to avoid intimidating his classmates and claims he forgot it. Excited for a mock battle with Claude, Cain’s enthusiasm turns to frustration as time runs out before his turn. Unable to release his pent-up energy, Cain vents in the forest, slaying monsters and causing such chaos that Garm and his knights investigate, fearing the return of the Prince of Darkness. In the palace, the king and Magna question Cain about the commotion. Though Cain initially hides his involvement, he confesses and apologizes after they discuss forming alliances to face the perceived threat. Meanwhile, Aaron senses his seal weakening, with part of his body now free. In an after-credits scene, Garm sternly lectures Cain for his reckless actions in the forest.
