What I meant about throw jinton I mean is if he decides to not to split plan he can just keep throwing jinton beams and going invisible while Kakashi waste chakra lol
Actually the only thing he can't do is jinton he can use his doton (and fire and wind release tho u dnt count them cuz dnt know what Jutsu he posses for those elements) also he can wait to heal up Kakashi will waste his chakra trying to fend off doton or trying to track him he doesn't have big chakra poll so I'm with Mū Sama on this ...
Also like u said nothing is stoping Kakashi from getting his head or Atleast stabbed in sharigan eye ...
muu wont be able to react. and split before kamui rips his head off ,he wasnt able to split before naruto attack so his splitted body was damaged too but for edo tensi regeneration
so when kakashi warps his head with kamui ,muu wont have the enought time to split and even if he could split, his splitted body’ s head would be ripped off too
whatever
also unki said that muu cant use jinton after splitting ,
dont talk as if mu was able to use jinton all the day, he has a limit and i dont think he can use jinton more than 4 or 5 times, but kakashi can use kamui 6 times with about 6 raiki and opened sharingan for a whole day
kakashi can counter the jinton by warping it before it gets bigger while mu charges it in his hand
