Naruto should be able to use 9 tails chakra on his own.
Sorry guys i wont be snatching any pictures mostly because i have no idea what number the chapter was.
So...... i just had this thought, shouldn't Naruto be able to go into a lesser version of BM without Kurama's chakra?
I know it sounds weird but Killer Bee was able to do it with his fight against Kisame.
I remember he was checking how much chakra Samehada could take at a time, and that obviously costs him allot of chakra.
And later he tells Gyuuki, (something along the lines of this) Hey could you borrow me some chakra i nearly ran out?
So all-in-all, i don't see why Naruto shouldn't be able to do that himself?
He is already connected to Kurama fully, and he has large chakra reserves, so i don't see why he couldn't be able to do it on his own untill he nearly runs out.
