Quote:For the genjutsu thing and Sakura's lack of practice at it, I've been planning to get around the question by saying that she's the first member of her clan in several generation to actually try and become a career ninja - so that, even if there were Haruno ninja involved in the founding of Konoha, most people -these- days think of the family as large-scale merchants... Haruno-san, Sakura's father, was, in my world, one of Gatou's major competitors, which she wasn't aware of because she was always more focused on Great-Grandfather's ninja stories... So, while the old clan techniques are still recorded, there's no one left alive who knows them - all the others either died of old age or had a bad luck day on the battlefield.
Aside from Sakura she's the only one we haven't seen older relatives of, and if having a dual self is a bloodline thing, that lets out Sakura... which begs the question of what benefit such a bloodline provides - maybe the Inner Self can direct to molding of chakra, to allow using techniques without motion or sound, using them while engaged in taijutsu to keep the enemy from having a chance to use theirs, or even two at once. Surely it can't be so common to (smirk) butt heads with the Yamanaka clan, and it certainly doesn't seem to have helped her any with normal genjutsu - she fell for Kakashi's, saw through the one at the beginning of the Chuunin Exam, got stuck runnning in circles during, then cancelled the one at the end - and both times she succeeded against one, so did several others. I suppose it could be a (lack of) training thing, but the point of a ninja clan is to train the children in certain special skills from a young age to give them an advantage as ninja, which would by definition include bloodline skills. I can at least point to her canonical excellent chakra control and say it's because Inner Sakura is doing the techniques in unison with Outer Sakura.
Your doing this is good too - it'll, mm, help distinguish the stories in the minds of an eventual audience.
Anyway, I can see another fairly major benefit to the double-mind thing - major enough that I think that it was likely the entire -point- of creating the blood limit in the first place.
Deep cover spy work. You condition and alter the outer mind until it -is- its cover... until not only can they pretend to be completely loyal in the manner that they were supposed to be, but they -believe- that that's who they are and always have been.
And the whole time, the inner mind is -still- -present-, watching and waiting and remembering -everything- it sees, undetectably.
Double-image chakra tricks, Yamanaka headaches, genjutsu busting... all that's secondary, stuff people figured out in order to make new uses for what they already had. Infiltration is the -point-.
Ja, -n
