An outsiders perspective
(POV Danzo)
Recent events had me considering breaking my own rules and killing that brat despite the clear talent he has shown and the great value he holds for the leaf in the future. It had all started when I met the boy face to face after Hiruzen nearly completely ruined years of work. The boy was no simple minded child and had sniffed out the problems surrounding the nine tails current hosts situation and past. I had specifically spread the rumor of the Uzumaki child being the demon fox in hopes of keeping him suppressed by the hatred of his fellow villagers.
Hiruzen likely had suspicions that it was the case but I had left no evidence behind to tie it back to me. My plan was working well too until Kenzo Mizuyama came into the picture and ruined most of it. The damned brat began to fix the Uzumaki childs intentionally created flaws such as his poor foundational knowledge and self confidence. While problematic this was still acceptable as so long as the child didn't learn the truth of his own significance and most likely seek revenge against the village.-
Just revealing the boys heritage got dangerously close to accomplishing this which was why I put a stop to that whole conversation after it nearly reached the point of being unredeemable. My small clash with Hiruzen was insignificant but as he had forbidden me from making a move on Kenzo I moved to intimidate the child instead since I had assumed that would bring him under control, I was mistaken. I am not sure how exactly the brat accomplished it but after that brief encounter I had been defecated on no less than fifty times by birds and been stung, bitten or harassed by many different insects hundreds of times.-
The worse part was that not even Torune Aburame who worked under me could find any trace of the insects being controlled via chakra or any other method imaginable. The brats affinity for animals was a mysterious and highly valuable ability and even secretly obtaining samples of his cells from his visits to the hospital from his regular check ups revealed no abnormalities. No kekkai genkai, mutations, chemical anomaly or other explanation for his ability to command seemingly all forms of animal life could be found.-
In fact through my thorough investigations of the boy he only had two facets that stood out with one he hid well but had been noticed by the people observing his body and the other being impossible to ignore. The first was that his body was extremely dense and despite the boy trying to hide it clearly had a very high amount of innate physical strength. The second facet was that the boy had frankly terrifying amounts of chakra. According to my Hyuga subordinate the boys chakra reserve was only lacking in comparison to the jinchuriki of the nine tails.-
This fact left me and many others in the village confused as the boy had no exceptional ancestry or strange mutation that would explain it. At the same time I had personally confirmed that he also wasn't secretly a jinchuriki that another village had slipped in as the current generation of the tailed beast hosts were all accounted for. Despite my own unwillingness I could only admit that the boy was the exception to the rules, an anomaly. Frustratingly though Hiruzen had noticed the boy slightly before me and had made it clear that I wasn't to bother the boy to recruit him or any such thing. -
It was a tragedy as I was sure that only I could fully utilize the boys potential while making him absolutely loyal to Konoha. After clearing the village of influenced insects and birds that would attack me I had turned my attention to a different matter of concern, the unrest of the Uchiha clan. It wasn't long after the new year at the academy started that it was finally time to wipe out this troublesome clan for good. Itachi played his part nearly perfectly but left a lifeline for the clan in the form of his younger brother whom I was helpless to deal with since Itachi had threatened to share village secrets to the other villages if I did.-
Hiruzen was also especially unhappy about the massacre and stripped me of a vast amount of my power by disbanding the root officially and integrating them with the anbu. It was a massive set back that forced me to temporarily suspend most of my plans. It wasn't a total loss however as I also obtained a vast amount of Uchiha DNA and sharingan eyes of various stages. Unfortunately I was unable to obtain Fugaku's eyes which were suspected to be mangekyou due to Itachi destroying them.-
That was when I obtained some rather interesting information on Kenzo, he was acting out of character after the massacre. For anyone not aware this would seem like he was in grief for the lost clan like he had friends in it but I knew for a fact he did not. The only Uchiha he had any real amount of interaction with was Itatchi's younger brother Sasuke and even then it was one sided rivalry from the Uchiha boys side. Yet despite this complete disconnect from the clan the boy acted as though he was the one suffering from it's loss.-
My intuition was telling me that there was something to this but I simply couldn't figure out what it was. The clan compound had seals in place to prevent sensor ninjas from peering into it so the boy couldn't have indirectly witnessed the massacre. I dug around the boy and sent probes to see if his adoptive parents knew anything but they were just as clueless as everyone else or at least appeared to be very convincingly. About a month after the massacre the boy had settled down but had a clear drive now that concerned me.-
The few things the boy had revealed publicly made him make even the fourth Hokage look normal as he had mastered two chakra control techniques at his young age that gave him chunin level lethality when paired with the strange taijutsu he seemed to be creating by mimicking his chakra beasts. The trouble Hiruzen would have assigning him a Jonin mentor and regular teammates come the boys graduation did nothing to ease my own concerns with the boy. He was already too powerful and by the time he graduated I very much doubted he wouldn't be even more powerful.-
Thankfully I knew that at most the boy would only reach special jonin levels of power while in the academy due to the severe restrictions that students had on jutsu they could learn. At most an academy student was allowed to learn C rank jutsu which was a rule even the clans respected. This meant that unless the boy somehow figured out how to create his own higher ranked jutsu from whichever ones his adoptive family got him to learn that was his limit and I know from experience working on vacuum release jutsu that this is no simple thing like improving ones chakra control.
