As Makoto prepares to wrap up the investigation of the Organization experimenting on demihumans, Shiki, Eris, Aqua express their dislike and distrust of Rona. During a one-on-one lunch, Rona warns Makoto about Shiki, Eris, and Aqua, as she once fought both with and against the lich and doesn’t know Makoto knows full well that they’re forest ogres.
Rona has fulfilled her mission in Rotsgard, so she’s headed back to the Demon’s Army. However, she gives Makoto what amounts to her LINE ID, so he can contact her telepathically should he ever require her aid. Always good to have one of the Demon Lord’s top generals!
After dealing with Professor Bright personally (and admitting he and the Org at least see eye-to-eye on the Goddess sucking), he continues teaching lessons to his students, now missing “Karen Force” but gaining the Rembrandt sisters.
Not only do they take every ass-kicking in stride, but they come to Makoto with a united voice, asking if he can keep teaching him during summer break. He agrees to weekly lessons after Shiki fails to make up a scheduling conflict, but insists the sisters return home for the second half of the break.
Just when the seven students, who through their trials-by-fire have become quite a tight-knit and cohesive group of friends, think they have a strategy to defeat the Blue Lizard, Makoto makes them fight two of them, albeit separately.
When the second lizard Zwei is called a jerk, she unleashes a can of extra whoop-ass on the kids, and Makoto apologizes, telling them that she’s a female and didn’t take kindly to the insult. The kids regroup and ask if they can go one more round.
After their training, Makoto takes the students out to dinner, and Shiki informs him he’s told them about the place where they can fight monsters and efficiently level up (they’re all members of the Adventurer’s Guild after all). But Makoto is still worried that they might face dangers if he’s not always present.
His solution, since he’s got ample bananas (for now), is to have Eris keep an eye on them on their training camp. When they pick a fight with a demi-dragon for whom they’re all twenty levels too weak (they’re all in the 70s), Eris traps it in roots and tosses it into the lake, deeply impressing and inspiring the bright-eyed novices. It is indeed going to be a summer to remember for all of them.
