I keep reading this rereading it again I can find a few people who should willingly teach her And I includes Itachi The master of his own Genjutsu with or without the Sharingan doesn't always rely on that to get results and is fighting techniques Ibiki The master interrogator and information gatherer and The perfect one to teach someone to be a perfect spy if you're going for the infiltration route and I hope I'm right on because he is a valuable piece and teaching people to keep their emotions more in check and spy work and information gathering Kurenai flexible with her abilities and dangerous but she's a master  but if she's good with any other jutsu perfect one for her to be her main master will be the Itachi knowing he mastered not just relying on one technique to get the job done but constant improvement and finding things she's good at that is not just Genjutsu could be effective and not be one trip pony like Naruto when we all think about it He relied on one jutsu to be overpowered and then he relied on the other one and just kept on improving even in sage mode he kept on relying it too much that is a weakness that can be displayed in a fight just got an angle it right to the elbow or the hand and make him lose control over as little tornado hand That's why I say Itachi would easily killed and captured Naruto if you wanted to and needed to and that can be easily shown to her because he could have easily grabbed that kid and ran knowing he's the master of Genjutsu no matter how much The toad sage boasts about his abilities there's always a weakness to him that could be easily displayed and that was women and him not knowing the true scope of Itachi and he was a good spy

Well I'm going to actually say it I actually love your story and your character because it does remind me of Itachi I like to say it here because it's not in front of the story but you pretty much mixed it in to what Itachi has felt being Genin He was feeling the stress of being involved in situations That's why I think Kakashi fucked up because he doesn't notice the same thing that Itachi went through she is going to pull Itachi by the order of the Hokage because she does care even though she looks cold and calculated she has a heart she mourned Kakashi secretly she cares about people she loves them hell The difference is with this if Itachi and her met they would understand each other quite quick by just staring at each other and knowing he doesn't go for the killing blow or hesitates He can hurt his brother and traumatize him for life but he didn't go for the painful blows to break his bones and think it's him terrified of him she can easily tell that because well she's pulling the same thing he pulls hold things in Don't show what you're truly feeling because that is pretty much what they thought being around people and in the village that demands that And that's why I think itachi and her clique because of the Genjutsu specialties because in that nature you have to be someone to be master of deceit And she would actually cry when Sasuke gets hurt in this mission think he almost died
