Talk:Kyoko Sakura vs. Madara Uchiha/@comment-27397663-20160402133522/@comment-2218433-20160402141552

Good points, but there's one thing about Genjutsu that make things difficult here, as it is stated on the Naruto Wikia's Genjutsu page:

"A genjutsu is created when a ninja controls the chakra flow of a target's cerebral nervous system, thereby affecting their five senses.​"

What stands out to me here is that it is to control the chakra flow of a target's cerebral nervous system, Kyoko would obviously have a nervous system, but she doesn't have a chakra flow, so genjutsu may not work on Kyoko because of the lack of any chakra within Kyoko.
