I'm a librarian who loves anime, manga, and reading a wide variety of genres.
This volume was a tad boring. Since there's more training (the Sage jutsu stuff), it was heavy on complicated jutsu explanations. I was also somewhat taken aback by how abbreviated (?) the grieving in this volume felt. One or several characters say that there's no time to grieve, and this carried through several volumes - a lot of tremendously bad stuff happens in the next few volumes, but, since the characters didn't get much time to process and feel it, it felt like there was less emotional impact.
Oh, and Eight Tails' jinchuriki raps when he talks. Reading his dialogue was so annoying that I found myself skimming it more often than not.
