well this chapter focused more on Naruto's training but also it featured the 3 tails Biju, the way this chapter started was a little confusing for me as in i didnt know how they managed to track the 3 tails so quickly and we dont even know who he/she is hehe.

Again i cant see how all the other Jinchuriki's are able to use all their Biju powers but Naruto cant, im guessing this has something to do with the seal. Also how strong are the Akatsuki members because they seem to be able to take out a Biju like as if it was nothing.
Now that we have seen the 3 tails the rumor about Kisame having it in him has been thrown out the window, but what i dont get is how strong he is they said that he has a huge amount of chakra comparable to Naruto.
