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?

They soon found themselves in another, bigger clearing with trees surrounding them, hiding them from prying eyes and allowing them some peace and quiet for training. Kakashi was waiting for them with Sakura, the man walking with the help of his crutches and looking downright exhausted to even be standing. Naruto did a quick sensory scan of the area and was relieved that there was no one else but them for miles. They'll at least be safe here, if only for a while. You never know when someone will walk by in the woods.

''Today, you will be learning to better your chakra control.'' Naruto perked up at this and even Kurama's ears jerked up when they hear these words. This was perfect! This was just what the blond needed to work on! It couldn't have ended up better if they had planned it! ''The exercise is to climb these trees without the use of your hands.''

''Then how are we to climb them?'' Sakura asked confusedly and Kakashi chuckled.

''Why, by using your chakra of course!'' When he got mostly blank stares from the genin, Kakashi sighed. ''Here, I'll show you. Concentrate on my feet.'' The three genin looked at said sandle clad feet and waited. Kakashi put his hands together and channeled some chakra down to the soles of his feet until it was visible, making the kids gasp. Not waiting for them to make some comment, Kakashi walked over to a tree and climbed up with ease, one step at a time. By the time he was standing upside down on one of the branches, the genin had recovered from their shock and were waiting for instructions. "Concentrate on putting chakra into your feet, think of it as water that goes from your core to your legs until it spreads under your feet. I suggest, as you're beginners, that you take a running leap. It will be easier that way."

The genin nodded, took a few deep breaths and put their hands together. Naruto was surprised at the ease with which he molded chakra in his feet but then tried to force down the instinct to use Kurama's chakra as well. They really didn't need for Kakashi to start asking questions about why Naruto could use red chakra instead of the normal blue one. Naruto was already going to be interrogated about his father by the jonin anyway, so why ad more to it? When they felt they were ready, the three gennin took off and towards the tree.

Sasuke's first try got him halfway up to the first branch of the tree before he was ejected from the bark because he channeled too much chakra. He quickly marked his spot and landed down on one knee beside the base of the tree. To his surprise, Naruto was there, too, having gotten only two steps on the tree before falling down and clutching his head. He had been so concentrated on not summoning up Kurama's chakra that he had ended up using too little of his own and fell down almost instantly. This was way too embarrassing to him.

"Hey guys! This is easy!" Both boys looked up to see Sakura sitting on the first branch of her tree, waving at them happily.

"Oh? It would seem Sakura has the best chakra control. As expected from Iruka's student." Kakashi's eye curled up in a smile. "You two ought to do better or Sakura will leave you behind in the dust." The two boys exchanged a look before getting up to their feet and stepping away from the trees. They put their hands together again and started molding chakra. Meanwhile, Sakura was resisting the urge to try and pummel her sensei's face in, as she now feared her precious Sasuke-kun hated her because he hadn't praised her for her success. She didn't want to seem like a show off in front of her love interest.

The second time they ran up the tree, Sasuke managed to get two more steps over his last mark while Naruto found himself ricocheting off the tree and through the forest, far away from his teammates. Thinking fast, Naruto activated both of his Kekkei Genkai and grew a thick but soft bush to catch him like a baseball glove would a baseball. The blond sighed in relief when he didn't break anything and had to listen to Kurama scolding him while he walked back to where his team was. Sasuke and Sakura immediately came down from the trees they were climbing and started fussing over him despite the biggest wound he had being the one to his pride. Jeeze, no wonder he couldn't use Mokuto without his Sharingan. But he guessed that was okay, as long as he didn't have trouble with his other techniques without the Sharingan. He had a theory that he even had the Sharingan at all to balance his Mokuton and Kurama's chakra inside of him. But he needs to learn techniques without it, too. And the first step to that end was learning some decent chakra control.

You drew on my power, Kit. You need to concentrate on your own and only add a little bit of mine if it's needed. Kurama told him as he prepared to mold chakra again. The other two genin saw that he will be fine and continued their own training, leaving Naruto to his own devices. Kakashi carefully observed how they were doing from his perch. You know how much it amplifies everything.

'I know, I know, dattebayo.' Naruto thought back irritably. He just needed a little of Kurama's chakra to punch through a tree. He had to be careful to not use much chakra in this exercise either. But it was hard separating your chakra from the chakra of the being that has been living within you for the past twelve years of your life, which is your whole life, especially since eight of those twelve years were spent mixing your chakras together.

But Naruto was nothing if not persistent and stubborn. His third try sent him flying back again, but only after he'd reached the hight of Sasuke's first mark. Thankfully, he wasn't flung halfway through the forest this time, but unfortunately, he'd stopped only because he hit a weak tree. It had been painful. When he tried the fourth time, he got to the first branch before he was flung back, but this time he didn't fly far from the clearing. On his tenth try, which was close to the half point of the middle of the tree, he was thrust back like Sasuke had been on the first try. By this point, Sakura was exhausted and lying on the ground, panting and spent and Kakashi had climbed back down from his perch. Sasuke was only a foot higher than Naruto but he was exhausted, too, so Kakashi called it a day and they went back to Tazuna's hut, where Tsunami was waiting with dinner.

There, they dealt with their exhaustion very differently. Sakura was so tired she barely managed to finish half of her meal before she fell asleep at the table. Sasuke and Naruto ate so much they almost puked it all out, but they remained awake. They then helped Sakura and Kakashi to their rooms before Sasuke also turned in for the night while Naruto helped Tsunami to clean up. Not long after that, everyone went to sleep but the Jinchuuriki.

In truth, Naruto was so pumped up from the exhausting training that he snuck out of the house and took off into the forest. He found the little clearing he had been in that morning and allowed his eyes to bleed red and for the Sharingan to activate. He then made a hundred clones of himself and started fighting them all. He would hit one and get hit by another and so on until he was sure he had enough bruises to last him a lifetime. By the time he finished with the last clone, it was midnight and Naruto reluctantly returned to the hut. He'll have more training in the morning, anyway.

And he was right. Kakashi woke them up at seven and they ate a light breakfast before they were back to the tree climbing again. Around noon, the silver haired man deemed Sakura had mastered tree climbing with chakra suction and she went with him to get the two boys some lunch. By the time Naruto and Sasuke came back at sunset, they each had only one fourth of the tree left to climb, much to Sakura's amazement. Kakashi commended them on their progress seconds before the two boys dove for the food. This time, Sakura was more than rested enough to snap at them for eating like pigs and yell some more when they ended up puking it all on the floor. Tsunami said she didn't mind but Sakura was worried and annoyed anyway.

That night, Naruto spent half of it in his head, meditating with Kurama. The kitaune told him it was also a form of training to get in touch with your innermost chakra and the two of them have been doing so until Sasuke rolled over and slung an arm over Naruto's waist. Startled, Naruto almost released all that gathered chakra out in the open had it not been for Kurama. Seriously, had the Kyuubi not been as quick as he was, Tazuna's house would have been blown sky high. The rest of the night, the gathered chakra bothered Naruto like a stomach ache, which was why he was so hyped up to start training the next morning, even running out of the house without breakfast. Sasuke, naturally, followed after him an hour later, only to find that a girlish looking boy was talking with Naruto. He had to quell his jealousy before he set the ... flowery clearing ... ablaze? 'Okay, just what the hell?! Flowers?! This place had no flowers yesterday! If Sakura or Kakashi come by, how does that moron expect to explain this!?'

For his part, Naruto had made the most of his free hour of training. First off, he had made a hundred clones and dispersed them throughout the forest. He then proceeded to make them climb trees like he was and he was now pretty much even with Sasuke. He then finally sat down on the ground, dispersed most of the clones and allowed most of the leftover gathered chakra out in the form of Mokuton. He heard trees growing at the places of the leftover clones and the clearing around him soon became as colorful as the other one, so he quickly drew the power back. Unfortunately, that had an interesting side effect. In other words, such a backwards rush of chakra knocked him out.

He then found himself being roused by a girly looking person only for his senses to tell him it was actually a boy a few years older than himself. The boy's name was Haku and he had been gathering herbs for a sick important person. Haku then proceeded asking Naruto if he himself had a person he would do anything for and Naruto flushed, thinking of Sas-

Haku more than understood his blushing state and continued to tease him about it. Naruto felt like he may have just made a friend when it finally registered. The cold feeling, the tint of ice he felt from the older boy, from his trained chakra system ... But no, that couldn't be! There's no way someone as sweet as Haku could ... but it was. Naruto's senses were never wrong. They weren't wrong with the Demon Brothers, they weren't wrong with Zabuza, they weren't wrong with Kakashi and they sure as hell weren't wrong now.

Which meant only one thing.

Haku was the boy who helped Zabuza.
