It's funny going back and forth between Yuru Yuri and Yuyushiki to hear Yui in essentially the same role. Ditto with Yuzu and Chinatsu. Hope I can see more of these kind of crossovers in the future!
Also, the afterword suggests this group's next work might be a Okaa-san (Matsumoto-sensei) or a SakuHima doujin. I'd definitely be up to do one of those in the future. :)
Edit: It's a SakuHima doujin. コスゆり. That explains the cosplay in this volume (Kinda).
