Books like Naruto, Vol. 31: Final Battle

It's really great to see how the characters have changed over their two years of training. Sakura's finally upheld her promise to become great and she's really turned into someone amazing, and even Kakashi learned some new tricks. It would be nice to see a little more development from Naruto since he seems to be using the same attacks and strategies as he did before, but there is a hint that he's learning to control his power more. Similarly, it's also nice to get a better look at the Akatsuki and some of the people that Naruto and the others will be facing off against.
