It seems that Genjutsu is being ignored when it comes to power boost, from Senjutsu. People claim that it is simply the "same" as if they weren't boosting it with Genjutsu via breaking out. So lets start from scratch here by reading Jiraya's words:
Jiraya explains that there is only two ways he explain.
"Okay we get that Ej--" No you don't get it.
"Jiraya said" is where I was getting at. Jiraya is only speaking from his own experience, when facing the Genjutsu's HE had to face with. But as we know through out the manga they are other Genjutsu out there I required something different other then Jiraya's method. One was, as you can say Demonic Flute, when pain can help break its bind. Another one is 2nd Mizukage' the most confusing one of all, if I may say, and last MS Genjtusu: Tsukuyomi.
Using Tsukuyomi would be the best example I will be using to get my point across, since its a "higher level Sharingan jutsu then the 3 tome Sharingan Genjutsu".
Here is the best example here:
Lets read "Chiyo's experience": [X] [X]. As you see here she was so confident in her experience that she thought out a counter to "Sharingan Genjutsu". But in the end, Kakashi breaks it to her here, sadly [X] [X] <--Chiyo. Kakashi was right in the end, a higher genjutsu means a harder, different, and to almost impossible to break out with it did to the lower tiers.
Some people even like to use perfect jinjiruki as an example: [X]. ERRNT! Wrong! Once again Bee is talking about his own experience when dealing with generic genjutsu. Nothing suggest that he breaks higher genjutsu that requires specific steps in order to break it. Naruto already comment that, even for a perfect jinjiruki that trained him, that he should avoid getting hit by Tsukuyomi [X] [X]. Bee does not have the requirements to beat Tsukuyomi, as it is not the same as the generic Sharingan genjutsu.
Now to get to my point, concerning Senjutsu: Genjutsu.
A lot of people want to bring out this comment (concerning Kabutos Genjutsu): "Kabuto uses Tayuya, So all you need to do break hurt yourself to counter her Genjutsu."
Wrong! as it was already explained that the Genjustu advances to a new power level with Senjutsu. [X]. A higher level from the Genjutsu means different requirement to break through since it is no longer a generic form.
This concludes that Kabutos genjutsu MUST BE BROKEN FROM THE WAY IT WAS IN THE MANGA. Breaking from the manga means its canon on HOW to break the jutsu. SO NOW LETS SEE HOW:
Commentary begins: Here we see Sasuke and Itachi getting caught by this genjutsu. As you see in the sound effects, Sussanoo is being removed due to being in Kabutos genjutsu. So that tells you some chakra sources are shut down with paralyses thatt help activates Sussanoo, this Kabuto commented that Sussano is vulnerable to sound attacks.
Here you see Itachi forming a plan in order to break the jutsu. Once Itachi told Sasuke to look at him, Sasuke just picked up and understood what they can do to release the Genjutsu, and that is genjutsing (lol) each other.
So that is the canon counter to break the Genjutsu:
1. Partner (check)
2. Genjutsu (check)
Using the genjutsu they had, they had to specifically attack each others brain. Manipulating the flow of chakra of each other, they accessed inside Kabuto's genjutsu to break down the bind.
Which concludes: Partner must be in the genjutsu to break you out.
Now I wonder how you break out of Demonic Illusion: Toad Confrontation Chant (via SM Jiraya's) hmm
