First of all. You Being a newbie, have no right to Call me a Fanboy.
I'm Just Backing up Jiraya. That does not Make me a fanboy! The word fanboy is seriously Overused.
And the Difference between all these People and Jiraya, is that Jiraya has Tons of experience.
And Experience counts, if you didn't notice.
EVERY JUTSU HAS A WEAKNESS.
And Manga states that a Genjutsu can be overcome by Disrupting one's chakra, and Jiraya knows how to do that.
The Only Genjutsu Jiraya would not be able to counter is Tsukuyomi
Stop Fanboying Itachi.
What does being new have to do with spotting a fanboy? Is there a fanboy club? If you act like one and sound like one, then you probably are.
This is about Itachi's genjutsu up against jiraiya. Jiraiya will not break that. No way in hell jiraiya breaks it. Most people don't even know they're under itachi's genjutsu until after some time.
This isn't Itachi vs Jiraiya where jiraiya will have a chance. Sure jiraiya is better than itachi at taijutsu and has some wicked ninjutsu and sage mode, but what does that help against itachi's genjutsu? One of the best ways for jiraiya to probably break itachi's genjutsu is with sage mode. When will he get time to go into that mode? He takes like 20 minutes.
Sasuke walked up to itachi (sasuke v itachi final battle), he was trapped into genjutsu before he even knew it.
I like itachi, yes. Am i an itachi fanboy? Maybe. But the fact is, itachi's genjutsu is in another class to everyone else's.
Because jiraiya can break kuranai's genjutsu, or sasuke's genjutsu means nothing. That's like him dodging a punch from rock lee (no gates), whereas breaking itachi's genjutsu is like trying to dodge a V2 punch from Ay.
