'Minato you brilliant bastard', Hiruzen mused.
He had taken a closer look at the seal after Naruto had revealed his instinctual knowledge. Minato and Kushina had faced the shinigami together for a reason he had not known until now.
Minato had found a forbidden technique from the second Hokage, one that, like the Edo Tensei and Shiki Fuin, accessed a nether realm. It accessed the 'third heaven' at the cost of one's soul in return. He used this to imprint knowledge into Naruto, using Kushina's soul as trade, when they passed. He noticed the seal was unfinished, as though there was some final key he never put in place, as though he just hoped for the best. Upon further examination, it was missing some form of... direction? Selection?
Whatever it was, the seal was still enough to apparently succeed, seeing as Naruto knew things he shouldn't.
'Crazy, Crazy bastard.'

Naruto worked day and night for a year at the library with his clones, quietly for the librarian's sake, to prepare for the academy. He knew he would have to be a prodigy to even accomplish average grades with the prejudice against him. But first, he would prepare for 'project turn Mizuki Sensei to the dark side'. He'd train physically, but for a 7-year-old Uzumaki, it wouldn't do much, that training would wait till the academy.
As a genin, he would need to be blooded. Mizuki was his shot at getting that blood before missions and a field promotion.
A field promotion was key for the plan 'deconstruction of Team 7'.
He would be *perfect* just to get under Mizuki's skin, while still getting a chance at the mythic 'scroll of sealing' itself. He would be the unspoken rookie of the academy, throwing Shinobi tactics to the wind, just to begin to fuel the hatred against him.
Truly, the people hating him was wrong and ill-advised, but it was still *understandable*, but a teacher, someone that works with kids, sabotaging one? That was a no-no, and there would be hell to pay.
His research was interesting. He learned about the more niche histories and mythologies of the land of Ninja. It was all very unique and cool in its own way. Ninjutsu wasn't available to him, but Academy stuff was.
Eventually, he met a very interesting character studying endlessly through taijutsu books in the back of the library.
"Hello, I've never seen you here, what's your name?"
"Oh...hi I-I'm Lee"
'oh'
"Hello, Lee, what are you looking for?"
"*mumble*-kra defe-*mumble*"
"I'm sorry, could you repeat that?"
"I wanna be a ninja, but I can't use Chakra!"
"Okay, so you're looking for material on physical training and Taijutsu?"
"Hey- oh, you're not laughing...uh...yeah."
"You know, we could see if we could find Might Guy."
"Who?"
"Guy, the best Taijutsu user alive."
"B-but why would he help me?"
"I mean, why would he help any kid? Doesn't hurt to ask."
"O-okay."
"Great, let's go find Jiji, he'll know!"
-----
"Naruto, please use the door, just because you can wall walk doesn't mean you have to use the window."
"But it's fun and the ANBU don't stop me."
"*sigh* Who is this young man?"
"Oh, this is Lee! We're looking for Maito Gai to see if he'll train Lee since Lee kinda has a problem."
"Oh, are you going to the Academy Lee?"
The boy locked his hanging jaw closed and brought up the courage to speak in front of the Hokage.
"Y-y-yes s-sir-I mean H-Hokage-Ssama."
"Ah, you're the one with the Tenketsu disorder, correct?"
"Yes Hokage-sama", Lee said, putting his head down.
"Well, Guy is probably at his home, I'll give you his address."
-----
"Ah, what are two most Youthful young men like yourselves doing at my door?"
"Hi Guy-sama, this is Lee, he can only use Taijutsu and I heard that you're the one to talk to about that.
Externally, Guy kept his face warm, but inside his heart dropped in sympathy. 'Well, when life gives you lemons'
"I see! You have been told correctly! Do you wish to know the power of Youth young Lee?."
"U-uh what's that Guy-sama?"
"You'll find out, Lee, bye-bye have fun!" And Naruto left.
(I know it's short, but it's fun)
