Hidden Genes
Summary: There is a type of jutsu only one shinobi could use,the Shodaime became famous for it being impossible for anyone who doesn't have his DNA, and even then it was rare. Sharingan is an Uchiha doujutsu,so no one can have it unless an eye is given, so why does the Kyuubi vessel have both?Why does he move like the Yondaime?
Naruto's presence was very much felt on the battlefield since he arrived. His senses proved to be irreplaceable when Haku would try to sneak attacks from random directions or multiply his reflections on his mirror when only one was going to fire. His Kage Bunshin also provided a lot more targets, which allowed Sasuke and the real Naruto to try and reach the edges of the dome to escape, but Haku was still too fast for them. There was no use in the two of them trying to run through the gaps in the mirrors and the mirrors were too hard to be broken. But Naruto had sensed that Haku was also tiring and had suggested they keep making him use his speed with futile Kage Bunshin attempts to leave the dome while they tried to attack Haku when he left the mirrors.
For that, Naruto had explained logically, they would need Sasuke's Sharingan (since Naruto had no idea how to explain to Sasuke how he had his own and really thought now was not the time to go into any theories he and Kurama had come up with so far).
And while Sasuke's Sharingan was developed enough to read Haku's movement, he was still not used enough to using his Kekkei Genkai to predict them. His perception was still too slow and not nearly good enough to copy movements, but he was slowly catching up to Haku, his eyes easily following the masked boy's change of mirrors. Haku had, of course, noticed it, too, and had realized that it was dangerous when Sasuke caught the edges of his pants with the Katon: Gokakyu no Jutsu when he was between mirrors while attacking the clones.
Upon looking at the Uchiha, Haku had recognized his deadly infamous and famous eyes and had known that it would end badly for him unless he ended the battle there and then. He had observed his opponents closely, trying to figure out which of the Narutos was the real one, which one he should attack. He had seen that the two boys were very close. They would protect each other. But Sasuke wouldn't jump in front of a clone, only the real Naruto. Haku didn't have extraordinary sensory skills like Naruto did. Nor did he have special eyes like Sasuke did. But he was observant and he had noticed that Sasuke could tell the real Naruto apart from his clones. He theorized it as a power of the Sharingan but he didn't care how Sasuke knew which of the blonds was real, just that he did.
So he watched Sasuke carefully and saw him glance to the side with those red eyes of his - just for a second - before returning to watching Haku. But Haku had seen where he had looked and he knew who he had to attack. So he sent two fakes to attack the real Naruto from the front, forcing the blond to focus on them so he wouldn't have the time to register the real Haku come at him from behind. He made sure the Uchiha could see his movements perfectly and threw his needles ...
Sasuke turned around and saw it and started sprinting towards Naruto without a conscious thought, not even yelling the blond's name to alert him to the danger ...
Naruto sensed a commotion behind him and turned around to check what was going on ...
Only for it to be in time for him to see Sasuke get impaled with two dozen needles when jumping in front of him to shield him from the attack but being unable to repel the attacks from himself. Only to barely be aware of catching the Uchiha as he fell, coughing up a little blood, suddenly a lot paler than he would usually be, his eyes no longer the vibrant red of the Sharingan, nor were they the strong black that they usually were. They were glassy at best, the light fading from them as he looked up at Naruto. The blond was in a state of shock the likes of which he had not even felt upon meeting Kurama for the first time inside his own head.
He had watched, frozen in place, as Sasuke had jumped in front of him, in front of an attack Naruto's Uzumki blood and Kurama's presence would have easily healed and he watched as he started falling over. The blond jumped forwards, catching his friend before he could hit the ground and the needles could be pushed further into his body. Sasuke seemed out of it as Naruto arranged the Uchiha in his arms, gazing up towards Naruto with unseeing eyes.
''Sasuke,'' the whisker scarred by called tentatively and Sasuke blinked in acknowledgment to him. Naruto felt a shiver run down his spine that had nothing to do with Haku's Makyō Hyōshō or any other Hyōton jutsu Haku had been using.
''Naruto.'' The Uchiha whispered just barely, a hand reaching up towards Naruto's face, a single pale finger touching the marks on Naruto's cheek that he had gotten upon receiving the Kyuubi as a baby.
''You just hold on, Sasuke.'' The orange clad tween said, rolling up one of his sleeves hastily, knowing how he could help his teammate. ''You're going to be alright, you'll see. You'll be as good as new.''
''You're rambling ... usuratonkachi.'' The Uzumaki was downright terrified by how faint Sasuke's voice was sounding. He startled when the slightly older boy gave a rough cough and had to steady him with both hands. When the coughs subsided, Sasuke turned his eyes back towards Naruto and pushed his hand a little further upwards so he could cup the tanned cheek. ''That man ... I didn't want to die until I killed my brother ...'' Naruto, fighting back tears and his panic, quickly took hold of the hand on his cheek and pressed it harder to his warm flesh, as though wanting to give some of his warmth to Sasuke. ''But you ... You ... don't die...'' No sooner than he said the last word in a rasp did Sasuke's cold hand go slack, limply slipping out of Naruto's hold.
The blond just sat there, cradling his friend's limp body, not hearing Kurama's frantic calls to him, not registering Haku's words of admiration towards Sasuke's end by protecting someone close to them, their important person ... He didn't register the single tear that slid down his face until it slid across a cut over his cheek and the sting of the salt from the droplet of water snapped him back to reality.
The sight of his friend's still body ... that chest not moving up and down with each breath ... those eyes closed once and for all ... no breathe entering neither mouth nor nose ...
Something snapped in Naruto, like a switch has been flipped and an uncontainable rage that rivaled Kurama's own flooded his whole body. His vision bled red like never before, a startling amount of energy flooding his chakra system and Kurama, for the first time since he met this Jinchuuriki of his, had no say in his chakra being seeped into Naruto's body. How could he, when the Eternal Mangekyo Sharingan shone through the fog, startling Haku when he saw the red eyes, the slit pupil and the ring with three loops held by three straight tomoe to the edges of his iris instead of his usually blue eyes. Before the ice user could react, red wisps of chakra started spiraling outwards from Naruto's body, coming together and becoming so thick they were practically tangible.
Naruto was trembling as the red chakra poured out of him, from both rage and grief, from the power he was channeling and from the over-stimulation of his senses as they became impossibly sharper. His nails suddenly grew longer and sharper, like claws, and his teeth did too, his canines becoming almost as sharp and prominent as a wolf's or a fox's, to be more precise. His whisker scars grew longer, wider and darker, resembling more Kurama's own than the three lines that usually adorned the boy's round face. All his wounds healed right in front of Haku's eyes, steam rising from them in thin wisps as flesh sealed itself, fixing all damage done previously. His muscles became pumped by the chakra and started shifting a little, promising greater speed, agility and strength than ever before. His eyes became narrowed and wild and his hair stood on end as the stream of power became more and more concentrated.
Naruto! Naruto, get a hold of yourself, kid! Oi! Don't ignore me brat! Kurama's calls went unheeded for the first time since he and Naruto talked for the first time, all those years ago. That's what extremely worried Kurama. Naruto had lost control. The kid was going to do something that he was going to regret later unless Kurama could reach out to him and make him snap out of it. But the likeliness of that happening while he thought the Uchiha was dead were the same as the likeliness of Haku betraying Zabuza. None. Absolute zero.
Naruto was currently blinded by grief and pain to such a degree that even his overly sensitive sensory abilities were useless. His eyes had seen Sasuke die and he thought that's what has happened. If he were to just look at Sasuke now, he would be able to see the faint rise and fall of the Uchiha's chest. It was slight and labored but Sasuke was definitely breathing. But Naruto didn't know that. He was now raging and hurting at the same time, wave after wave of both emotions washing over him like a tsunami.
The closest Kurama could compare Naruto's current state to was the emotions he had felt raging inside of Uchiha Madara whenever he thought of his deceased little brother and he could recognize it with ease. How Naruto had fallen to the Uchiha Clan's Curse of Hatred when he was an Uzumaki and only had the Sharingan through unknown means, the Kyuubi no Kitsue will never understand. But one thing was clear. Unless he could snap Naruto out of it, his rampage could really end up killing Sasuke and if he somehow gets stuck in blood-lust, he'll kill others along the way. He will regret it and hate himself for the rest of his life. And Kurama was not going to allow that. He needed to drag Naruto away from that edge that many Uchiha had fallen over before he was lost to that darkness for good.
And it ain't going to be easy.
Meanwhile, Haku had sensed the immense change in the boy he had met in the woods, not so long ago. It was pretty hard not to, when Naruto's killing intent was actually channeled Kurama's killing intent, only used by Naruto in his grief, pain and absolute rage. Haku knew he would have to end this quickly or else Zabuza - and everyone else, including himself, not that he cared, though - would also be put in danger by this boy. No, he couldn't think of him as a boy three years younger than him, the first and closest thing he has had to a friend since the white rabbit Zabuza caught for him. It would make him hesitate. A good shinobi must not hesitate in making the killing blow. It could cost them their life, their dream. It would cost Zabuza his dream.
For Zabuza, Haku will kill his heart by killing this boy. Everything for Zabuza.
But it didn't matter that he was actually ready to kill Naruto now. He was not fighting the same boy anymore. He was fighting the Kyuubi's Jinchuuriki, something that Haku knew nothing about. He was never from any shinobi village, not really. He knows nothing of the biju and their hosts. He knows nothing of their power. So Naruto's new abilities, his speed, his strength to actually break one of Haku's ice mirrors ... Haku was flored by them. Naruto's movements ... It was not something Haku had ever seen before, the way he twisted his body with an agility and grace one so young should not posses, especially not at this speed. For the first time ever ... It was he who could no longer keep up. It had never happened to him before. He had never before met someone who could match his speed. Sasuke's red eyes had been the first but this ... This was terrifying. Haku for the first time was faced with the possibility of dying as Naruto caught his arm during one of his attacks. The clash of Haku's freezing chakra and Naruto's boiling one made steam rise out of the mirrors of ice surrounding them. The impact reached Kakashi, Zabuza, Sakura and Tazuna and even the only non ninja in their group could feel the wrongness of the energy in the air.
Kakashi was the only one who understood it. Who recognized it. He had sensed this chakra before, twelve years ago on this very same day, when his sensei died and a lot of people were killed in the attack of the creature that this chakra originally belonged to. Kakashi paled at the thought of what could have possibly made Naruto lose control enough for him to loosen the seal on his stomach to draw on this horrible power. It could not be good. Kakashi did not want to think about it. It would only lead him down a dark road himself. He needed to stay cool now so he could possibly go and save Naruto before the boy fully lost himself. He would not allow the blond to die on his watch. He will protect his sensei's kid. He just hoped that what he feared triggered this hadn't actually happened. It would be too much, too big of a loss, to him, to Team 7 and to Konoha. Kakashi won't allow it to happen, so he took out a scroll from his jonin vest's breast pocket, unrolled it, swiped some of his blood from his torso where Zabuza had cut him earlier and drew a line across the summoning contract before rolling up the scroll once again, making hand seals around it. When he was done, he crouched down, placed the scroll on the ground and whispered.
"Kuchiyose no Jutsu."
Although nothing happened, and although Zabuza could also not see what Kakashi was doing, he had felt Kakashi's chakra spike and he knew the Leaf jonin had done something. At the moment, though, he was wondering what had caused such a puring out of that evil energy he had felt before. He hoped Haku was alright, feeling the first spike of worry for the boy in years. He had only worried about the boy when he was a defenseless child that needed his protection still. As Haku grew stronger, he had stopped worrying. Now all the wordy he had had no reason to feel all these years returned tenfold and he could not help bit fear that he might not see his partner again in this world.
And he was almost correct. Haku, although strong, could not go up against the Jinchuuriki of the strongest if the nin tailed beasts. Naruto had overpowered him and even delivered a devastating punch to his masked face that broke Haku's nose and busted his lip. The teen flew right through one of his mirrors, it, too, breaking under the impact before sailing through the air another twenty feet or so, rolling a few more feet once he painfully hit the ground. Naruto let out some more of his chakra, allowing it to lash out at the ice mirrors still surrounding him, before he lunged for the slowly rising older boy.
And as his mask crumbled, Haku thought that this was a fitting end for a shinobi tool like him. He had been defeated. Zabuza-san didn't need a defective, useless tool. If he dies now, he will save Zabuza-san the mindless, tedious task of having to kill Haku later. He was just sorry that he had not been able to protect and help Zabuza-san better. After all, the blond boy coming at him seemed to no longer have any conhreat thought left other than to kill. And that was Haku's fault, too. He should not have hesitated to actually go at the boy with the real intent to kill when he had attacked earlier. Perhaps this could have been avoided had he killed the blond first. But he had hesitated and not only he will pay the price for his foolishness. Zabuza and possibly countless others will, too. He at least deserved it. In the end, he had not been a good shinobi, a good tool. He had been unable to kill his heart.
And as the remains of his mask fell and Naruto saw the face of his somewhat friend, something in Naruto hesitated, tugging at his heart. Kurama seized it like a lifeline, as soon as he felt it, knowing this was his last chance and that he could not afford to lose it no matter what if he wanted to get his Kit back.
He broke free of whatever restraints Naruto had unwittingly placed on him and yanked back at his power in a tug of war, startling Naruto out of his fit of rage long enough for Kurama to get just one sentence that could change this whole situation in.
Naruto, Sasuke's still alive, he's still breathing!
