I don't recall Naruto using any of the Kyuubi's chakara against Kakuzu.... If he did, it was just to use its chakara in order to form the RasenShuriken, but yes... If it was not for the Kyuubi, Naruto would be dead now- he would've died against Haku....
When will we get Naruto chapter 523??? It's been two long weeks and *********** hasn't posted ANYTHING! Chapter 522 didn't say anything about there not being a chapter last week... so where is the new chapter?:confused:
