Rep+Yeh they mastered shape manipulation so they can do rasengan rite" well guess what naruto can do rasengan to if u somehow missed that.
So Konahamaru hasn't master shape manipulation either
Do u understand how wrong what u said is, how the hell can a technique that is the highest level of shape manipulation be done by someone who hasn't master shape manipulation. DO YOU UNDERSTAND HOW SMART YOU ARE SOUNDING.
Why then didn't naruto suddenly master shape manipulation at the valley of end, where he did a one handed rasengan?
Very well said.
