Thanks for the long ride, hopefully the author starts picking back up the pace with this series. He's kinda slowed down after konosuba ended so I'm guessing he's taking a break and releasing when he feels like it now but I prefer that over him stopping completely.
I know it's been a while since I read this but who was the girl on page 24?
Edit: I figured out why she showed up in the flashback, she was the student who was saved by the doctor and got turn into a yokai.
I mean, it's a good thing she notice something was wrong immediately but I guess it was too much to realize that your child switched genders. I mean, it easier to assume this is someone else's child.
