im sorry what did frog song do?
Jiraiya's Genjutsu was successful because he had partners ofcourse. While the two old frog sages had the paths in a genjutsu Jiraiya was able to move around freely and kill the bodies.thats right then y did j-man win from genjutsu then
Itachi does not have the luxury of moving around freely while his target is in a Genjutsu. All Itachi is doing is stalling if he puts Deva in a Genjutsu, no matter what kind because in order to attack Itachi will have to first release the Genjutsu and since a zombie path cannot suffer from mental damage (like Kakashi) for Itachi to capitalize off of then as soon as the genjutsu is done Deva can continue his assault on Itachi like he was never in a genjutsu in the first place.
