Ok guys, i was completley wondering, the orgin of the move rasen shiruken was to cut up all your chakra points and blood cells to make you pratically defensless (correct me if im wrong) like when he did it on kakazu, but when he fought pein and did rasen shiruken on the pains, the completley desinigrated (pardon my grammer) but can some1 explain why did it not disable pein like kakazu or was it a error on naruto behalf?
