Captain Murphy is a pretty capable guy, but he’s never met anyone like Kirito. Kirito can move at extremely high speeds and his duel wielding abilities ensure that no opponent can defeat him in close quarters. Kirito will also never be hit by a gun since he is far quicker than any bullet or laser blast. Lets just face it, Captain Murphy has no way of actually hitting the famed swordsman and that will be his downfall. Kirito wins.
