I keep hearing how Naruto hed back, how a Kyuubi Powered Rasengan would "rip Sasuke's head off." However, realize that Sasuke did NOT kill Naruto. Its not that he cannot, he DID not. Remember, the Chidori is not some bs move. its is also an extremely powerful attack. It punches holes in just about everything, whether it be rock wall and people. I refuse to believe that a jacket could stop a LV2 curse seal Sasuke chidori, which is especially designed to pierce stuff.
