but can he do it? and even if they are moving there are many ways for kakashi to use kamui to kill kakazu but i just want to know if ts theoretically possible. please tell me what you think not weather or not he's done it before. for example tsunade has not been seen putting chakra in her legs to make her faster but it stands to reason as the ultimate medical nin she can do this right?If it was that easy, don't you think he would have already done that to Obito?
besides it has to be within his view. He can't just teleport something behind them if he can't even see what's behind them. Plus, they're moving targets.....they're not just gonna stand there and wait for something to teleport right in their face.
so based on that principle can kakashi warp a kunai or shadow clone to the other dimension and make it appear beside,behind, above or in front of the opponent? if so then kakashi beats kakazu mid diff cuause then its just about getting him in the right position for that kind of attack
