Shounensuki's Naruto 519 Spoiler

Naruto's gonna learn a new Rasengan it seem..

B explains the Bijū Ball to Naruto. The blast of chakra the Bijū spit out

From what i can tell, Naruto cannot change into Bijū Form so cannot do the actual Bijū Ball, but somehow the Rasengan is similar to it, so B and Naruto try to alter it into a Bijū ball

Naruto cannot actually change into the Kyūbi like the othre jinchūriki can

Apparently because that requires the cooperation of the bijū themselves
