no it doesnt
how did danzo manipulate mifune then
plus itachi can use crow shadow clones that put nagato in genjutsu, koto can be casted then too
Danzo was sitting right in front of Mifune. It would have been a small issue to lift up his eye bandages and cast KA.
Shadow clones also run into the disadvantage of needing Nagato to look at their eyes or fingers to cast genjutsu, and would be destroyed easily before even getting to him thanks to Animal Path summons/Asura Path missiles/Asura Path chakra cannon/Shinra Tensei.
except he already did it to Nagato.
Except Nagato was standing still and had mobility problems. As I pointed out in the post that you replied to.
and KA doesn't.
It did when used with the crow. I am not going to pretend as if that is not the case here when that has been the case for every Sharingan genjutsu to date.
