I am not talking about sousano ma boy, I am talking about how was he able to take it back from karin body, it took him so much to do.that which means it was really something hard to do, so how was he able to do that on the first try, and if you saying he naturally used it then the same can go with kakashi's PS,
And again kakashi was able to skipe the stages because he had all requirements to unlock it, chakra, eye's, and help from an uchiha, he had every thing he needed so why not stop *****in and accept that kakashi is more talented than most uchiha
