Re: 553 predictions/spoilers
What has Itachi to do with the Rasengan? It's not one of his moves, it's not characteristic to him to use something like Rasengan when he has such an array of jutsu.Honestly i don't see how you reached the conclusion that it may be Itachi.
Also Konohamaru is not Naruto to just "sneak" into the war. All the Genin's are kept aside from this war to prevent their death. A kid with a chakra ball as best offense jutsu doesn't stand a chance against a Dust element user. I must say that even the Jonins like Kakashi don't stand a chance against Mu. It's obviously Naruto. Gaara's exclamation supports that. The Rasengan supports that. The bunshins he made supports that. Apply Occam's Razor. So, it's Naruto.
When other men blindly follow the truth remember:
Nothing is true!
When other men are limited by morality and law remember:
Everything is permitted!
We know the light...but when we shall create the dark?
