i dont think he could cut through it a kirin. kirin was suppose to be a jutus on a different level since it uses nature and the chakra of nature itself. thats why he created the thunder storm to begin with. kakashi just changes his own chakra into lighting same as sasuke with chidori. it can cut a normal lighting blade and even penetrate A's lighting armor because it was the same as the third raigekages technique which he puts all the charge only in his fingers. they're all on different levels even when sasuke did hit A, A wasnt charged up all the way so you never know who would folded then. anyways back on topic kirin is natural lighting infused with chakra it wouldn't be cut by a lighting blade. itachi was worn down and all, but he moves faster than kakashi he shows it multiple times in the anime/manga. first time they met again after the third died he crazie owned him that whole thing showed him moving faster than asume kurini and kakashi. and the second time naruto took a fake itachi at 40% chakra out with the help of kakashi who was slower than itachi then. kakashi throws kunia at itachi he dodges and makes hands signs to launch a fireball the same time. he out match sasuke during the shoot out and in any direct confrontation like he does with anyone just think about to all the moment. itachi out match killer bee in speed of jutsu even as well was the only reason bee and naruto got away from nagato. anyways back on topic if itachi couldnt move from a lighting strike of kirin i doubt kakashi who is slower couldnt move fast enough to get there. even so theres the speed factor gone aswell and not to mention if he did karin it would be at the end of a fight or if he knew he could crush them like he wanted to do to naruto sai yamato and sakura at the beginning. but they would fight and kakashi would be weak even if he mustered strength like in the anime when he was young with guy its not karin susannos about the only thing it could stand up too. just like it did with raigekages power bomb he did to sasuke. hell they make sure and yank madara out of susanno so naruto can hit with his wind rasenshurikan so it can actual do damage. hell ligtingings suppose to be weak against wind but not the thirds armor. so it all depends on the strength of the ninja preforming and sasuke would out do kakashi. he held his own when he was weak after he murdered danzo like 15 times. think if he didnt have izanagi it would have been over at the squeeze. lol full powered sasuke yea raigekage couldnt get that done gaara saved him, his susanno would have grown more while A's legg burn off. i watch the ep today all the thunder people were scared sasuke barely shook. so yea theres alot more to look at then just the friction or whatever the **** you wanted to take about with your big ass words that no one cares about makes you look retarded more than smart. i have to friends in in Stanford law school and they dont talk like a total jackass. not even steven hawkings sounded like that in his robot will chair that talked for him. go on you tube look up lectures on anything they dont sound like you. you could have told us with normal words and sounded smarter. work on presentation. i mean i know im all over the place but im a normal guy who likes naruto. not someone who tries to write a science novel on naruto using big ass word that dont help the explanion of your theory one bit just makes you come off as a narcissistic nerd who tries alittle too hard. maybe you have a hyperinflated ego idk remember im just a naruto lover an a rambler lmao
