I read the print book, not the Kindle Edition, but I couldn't find the print book to leave my review so I'm leaving it here.
Well, it's done. This is definitely a series that I finished more because I got too far into it to not finish it rather than one I enjoyed to the end. I actually enjoyed this last volume more than I've enjoyed previous ones, though, so at least it finished strong.
It's just ridiculous. Most of the characters are annoying and some are even unlikeable. Yoshiko was unlikeable to me by the end, and given that she was the main character, that definitely took some of the enjoyment for me.
It's a quick read, though. And although the humor wasn't to my taste, that doesn't mean someone else might not like it. This said, I'm glad this was the final volume.
