Just finished reading the volume after starting it the other day. I definitely liked the comedy in this volume. I think one of my favorite scenes that was funny was Nem holding onto Duplichiro's waist. I wish there was an illustration for that considering how silly it is.
Regarding Rosemary's avatar, I'm guessing it was generated based off perfection taken from all the players which is probably why she looks "familiar".
The idea that the author could write a weeaboo character so accurate makes me feel shame as a being also shaped as a human. I wish I could turn into an AI and run away.
Regarding Asuha wanting to visit Seattle. The Mariners suck. Thus, the reason she wanted to visit was because one of the players formerly on the team is named Ichiro. If that's actually true, good on the author for being able to catch that bit of trivia.
