Training, Studying, Helping Mizore Study, and Jerking Off.

Naruto started his day off by training, and then he continued his day by helping Mizore study while he himself studied with his shadow clones, and then he went to the hospital to do his daily semen supplying for the fertility drug. He did his rounds around the village, helped named babies, and did work that needed to be done while he was training. He still counted that as training though, even though it didn't really amount to much growth.

Time passed.

It was a few weeks away from the time he would start attending school, and he had gone through another growth spurt, bringing him just shy of 166 cm tall. He was now actually taller than Mizore by a decent amount, since her height was only 155 cm, and she had finished filling out. Her breasts that were once small, were not a modest average size. Unlike him at 14, she was 15 years old, and had finished her final growth spurt.

She also got a haircut.

All he did was ask her if it was hard to take care of her messy hair, and she cut it to chin length by the next day. No hesitation, just him asking if her hair was hard to take care of inspired her to chop most of it off. She seemed really happy though when he told her that he liked the new cut just as much as he liked her older hairstyle.

"Why are you still studying, you got into school?" Mizore asked as she leaned over the table. She had given up studying, well at least until they were in school and actually had to study. She was watching Naruto study, which was good enough for her. "Is it because Pervy Old Man wants you to be the top student?" Mizore questioned.

Naruto nodded.

"Yeah, I've got to study as hard as possible to get to the top and stay there. Also... I think this is helping me with my training in other areas." Naruto stated with a small frown. He lifted his hand up, and he formed a Rasengan above his palm. Mizore just watched as the yellow spiralling sphere appeared, and she noticed that it was a brighter yellow than before.

"It's brighter?"

"I think when I study, I'm making my spiritual side stronger... Ninjutsu is formed when you use chakra to balance physical and spiritual energy. Training your muscles, stamina, and body makes physical energy stronger... but to get a stronger spiritual side, you have to train your chakra, and meditate, but also you can train by studying... my spiritual side is getting stronger when I study." Naruto wasn't just studying his school subjects, he was studying the basics of chakra control, and his ninjutsu studies to add onto that. He had decided that if he was going to study, he would add something that benefited him personally to them.

By studying, he was expanding his knowledge.

By expanding his knowledge, he was bringing his physical body and spiritual energy in balance with each other, which was resulting in increasing in his chakra techniques growing in power. His Rasengan was slightly more powerful than before, just by studying math and science, he was growing stronger. His body was even getting stronger when he used chakra to enhance himself. He didn't realize that the enhancements you got by channeling chakra got better as you studied.

He had no idea that he could actually get stronger by studying.

He also wasted less chakra when he used techniques, meaning studying was bringing balance to his chakra AND making him stronger, while also making his chakra techniques less chakra costly.

"Too bad studying doesn't make me stronger." Mizore complained as she leaned back.

"Also, science is helping me. Watch this..." Naruto stated as he held the iron ball that Jiraiya gave him up on the palm of his hand. It was small, so Mizore had to get a closer look at it.

*Chip*

"See... I'm suppose to cut it in half, and wind chakra is suppose to be sharp. Well, I was reading this, and it said that things get sharper by getting thinner... so I've been imagining myself splitting my chakra in half, sharpening it against itself, and then bringing it back together denser than before." Naruto studied the science behind sharpness, and it was resulting him drastic improvement in his wind chakra training. He just needed to work on instantly releasing the wind chakra at a density that could cut through iron with ease.

He would have instantly cut through most things that weren't iron, the fact that he cut a chip into the iron just implied that he hadn't released the chakra fast enough and made it dense enough. He was looking towards science to help him figure out the trick, since Jiraiya expected him to get results.

"So... is wind chakra... powerful?" Mizore didn't know about this chakra stuff.

"Not a clue, but it's part of me, so I'll master it." Naruto didn't know how powerful this skill was, but if Jiraiya wanted him to learn it, he would assume that it was to his benefit in some way. There was little reason for him to try and make a technique. The Rasengan was hard enough to learn and master, so it was hard for him to imagine something stronger than the Rasengan.

Actually, why should he learn elemental nature, when he could just use the Rasengan against most enemies faster than he could do handsigns? The Rasengan was clearly a superior ninjutsu to most, and he had mastered even more powerful versions of it.

"So... why?"

"To be able to make my own Ninjutsu that suit me."

"I think the Rasengan suits you though... so why bother with more, can't you just... make the Rasengan more powerful?" Mizore didn't understand why he wanted to add more techniques to his already powerful arsenal. Mizore lifted her hand up, and Naruto watched as ice started to form over her hands, until she gained ice claws around them. "Yuki-onna can only manipulate ice and snow, nothing else works for us. If we want to get stronger, we just learn to use ice differently." Mizore couldn't imagine the ability to be able to learn new abilities.

Yokai had the abilities they were born with, and nothing else.

"Yeah, I'm not that good at handsigns, so it might just be better for me to try and use the Rasengan and just use a wind kunai or something... to... cover close combat..." Naruto slowed down as a small idea came to his mind. An idea then nestled itself firmly into his skull that he wanted to try out. He looked at the iron ball in one hand, before he made a Rasengan in his other hand.

Could he wield a kunai covered in wind chakra, and a Rasengan, at the same time and improve his close combat powers.

Thoughts for later.

"Wait, no... not thoughts for later, thoughts for now... Wind chakra, Rasengan... screw this iron ball." Naruto tossed the iron ball that Jiraiya gave to him to the ground.

-At the Naruto Training Ground-

"Multi Shadow Clone Jutsu!"

Naruto pushed himself and summoned 1000 shadow clones, all of which were already wielding kunai with grins on their faces. The second he walked through the village to go to the training grounds, he was followed by a few dozen yuki-onna holding onto their babies, who followed him with smiles, and Mizore who had taken her usual place behind a boulder.

"Well, come at me then!" Naruto charged towards his clone army.

Screw the iron ball, he already had the basics of wind chakra, and he had an idea coming into his mind, and he needed some adrenaline in his system to get his idea turned into a plan of action. So, Naruto wasn't wielding a kunai, instead he was wielding a pencil, and he was surrounding it with the most basic of wind chakra. The pencil became a real weapon as he hit a kunai wielding clone's weapon with it, and the pencil was safe, not cut through in the slightest.

The clones kept coming.

Naruto formed a Rasengan with his left hand, but he stopped channeling wind chakra with his right hand, so he jumped backwards. He popped a dozen clones with his Rasengan blast, before he formed more wind chakra over his hand and pencil. He blocked a kunai with it again, and he jumped back more when the second he started to make a Rasengan, the pencil in his hand was cut through, the wind chakra he was forming weakening.

"... Shape Manipulation and Elemental Manipulation... I can't do both at the same time." Naruto realized a flaw in his training, before he grinned at the clones that were still coming at him. He engaged in more high stress training as hundreds of clones attacked him, and he forced himself to keep trying. "You guys do it to! Cover your kunai with wind chakra, use Rasengan! Come at me like I'm going to get killed!" Naruto wanted the training to really mean something.

-Later-

Naruto was panting.

"Multi Shadow Clone jutsu! Come on guys... round two... I'm getting closer, my wind chakra is getting sharper too." Naruto felt himself improving with each and every clone he defeated. His pencil had long since been destroyed, so instead he was just channeling the wind chakra through his hand, and forming a blade of pure wind chakra out of his wrist.

The clones roared and charged him down.

With each clone that used wind chakra that he defeated, his wind blade got sharper, his mastery over the chakra itself improved. He collided blades against the clones, and he improved, because if he didn't improve he was going to get his arm cut off.

Not a single clone managed to perform wind chakra manipulation and a Rasengan at the same time though, and whenever one of them tried to do it, they would be forced to chose between the Rasengan or wind chakra. It was extremely difficult to manage to do both at the same time, to wield an enhanced kunai and Rasengan hand in hand was no easy feat.

So, the training continued.

"Rasengan!" A clone shouted as it approached Naruto.

'Here it comes.' Naruto thought as he saw the clone about to try and manipulate wind chakra and create a Rasengan at the same time.

The Rasengan exploded in the clone's hand all on it's own though, popping the clone as a sharp feeling in the air washed over Naruto. He was blasted off of his feet, and several clones around that clone was knocked back, but still active.

'Just for a second, the Rasengan... glowed brighter, and I thought something looked like it was coming out of it.' Naruto saw 2 more clones approaching him, both of them wielding wind chakra kunais. One of them started to form a Rasengan in his hand, while the other one stopped being able to channel wind chakra as a Rasengan formed Both of their wind chakras went out, but the one on the right exploded when it looked like the Rasengan in his hand started to form blades out of it's core. 'What!?' Naruto was knocked back by a 2nd clone blowing itself up.

What was that?

'It was trying to channel wind chakra and make a Rasengan at the same time... and some of the wind chakra... did it get mixed into the Rasengan?' Naruto jumped backwards and kicked a clone as he thought about what he had just witnessed. It was a complete accident, the clone was trying to use a Rasengan in one hand and wind chakra in the other, but was accidentally putting out wind chakra from the same hand as the Rasengan.

Naruto noticed 2 more clones explode as they charged up Rasengans with wind chakra getting mixed in, and as clones popped.

"Rah!"

"Not happening!" Naruto formed a Rasengan and clashed it against a Rasengan from a clone.

The 2 Rasengan cancelled each other out, but Naruto felt a sharp, stinging pain in his hand as a deep cut formed on his palm. He kicked the clone that he clashed Rasengans with and popped it, and kept battling. The 2 Rasengan cancelled each other, but somehow he had taken damage from the cancelling... but the clone hadn't taken any damage.

'With each clone I fight, the clones get better and better at wielding wind chakra, not just me... both me and the clones are all sharpening each other's skills... its like each time I pop a clone, all the other clones learn from it's mistake, and I learn too.' Naruto grinned to himself.

This was the right training from him.

"MULTI SHADOW CLONE JUTSU! MULTI SHADOW CLONE JUTSU!" Naruto charged up his chakra massively twice, and summoned 2000 more clones. The entire section of the woods he was in was filled with nothing but him and his clones. "Come on, I can keep going all day and night!" Naruto roared out to his clones.

Naruto rushed to the massive army.

He formed a Rasengan, and the front row of clones he got to formed their own techniques. One of them managed to wield a wind chakra kunai and a Rasengan at the same time, but the wind chakra was weaker than before, while another of the clones had a Rasengan that had those same tiny wind blades forming on it.

There was an explosion.

More clones exploded as their techniques backfired on them, but the more closed that exploded, led to more clones that started to succeed in what they were doing. Naruto blocked a wind kunai with a kunai palm of his own, and he created a Rasengan to cancel out a Rasengan. He fought himself evenly, and above evenly. While the clones lacked any self-preservation instincts, he had them and fought even harder than the clones did to protect his very life.

When a clone charged at him with a Rasengan that had a little wind chakra in it, Naruto had to try his hardest to match the clone. So, he formed a Rasengan in his hand, and then he took the flow of wind chakra away from his right hand, and pushed it towards his Rasengan instead. Small blades of wind formed around the Rasengan, and he collided against the clone's Rasengan... and the techniques didn't cancel each other out this time.

Naruto won.

He created a more powerful Rasengan, and the clone was popped, and a tornado of spiralling wind and chakra blasted through several dozens of clones behind that clone. Naruto still had to fight more clones though that were surrounding him at all sides. He didn't have time to celebrate what he had done, or think about what he was going to do next. Instead, he had to rapidly improve.

Clones were starting to match him.

His success brought about progress in the clones, who were starting to abandon using kuani altogether when they saw how powerful mixing Rasengan with wind chakra turned out. Half of the clones who attempted this popped themselves, but the other half of them succeeded in doing exactly what the original Naruto had done.

After 4 more hours, not a single clone was exploding from failed Rasengans.

"Not what I intended to do, but this might be even better... heh... next time I see Pervy Sage, he's going to be... in for a surprise." Naruto stated with a grin as only him and 10 clones remained, all of them, himself included, were wielding Wind Style: Rasengan in their hands. The training ground was gone, they were standing on a complete crater caused by many hundreds of explosions.

Naruto himself was cut, bruised, and bleeding all over from released wind chakra that had ravaged his surroundings.

"Haaaaaaah!" One of the clones put all of his effort and chakra into enhancing the Rasengan he was using as much as possible. The technique's wind blades started to grow, and they grew large, before the technique became unstable.

The explosion was massive.

Naruto was just outside of the blast range himself, but all 10 clones he had been facing had been destroyed. He was also blasted back by a shockwave that knocked him a clear 40 meters away from where he was standing. He landed on his back, staring up at the night sky. He looked at the Wind Style: Rasengan in his hand.

"Heh... hahahah!"

Sitting up and laughing, Naruto's blood fell from his face, into the snow, and he grinned.

"So... lets see..." Naruto placed his hand on a tree, and he cut it down with a burst of mastered wind chakra. "... doing this helped me master wind chakra way faster than cutting some iron ball... and now I have a new technique... and now... I have a new goal. That clone was onto something... he didn't have enough chakra to keep it stable... but..." Naruto's eyes went fuzzy.

The adrenaline wore off.

Exhaustion hit him, and he collapsed into the snow.

"Heh... now I have a goal to strive for... that technique the clone started to use... I'm going to master it. Pervy Sage is going to be so impressed." Naruto didn't even have the energy to stand after his rough training.

"Are you okay Naruto?"

"Not at all, I'm... exhausted." Naruto couldn't stand on his own anymore. He had pushed himself to the limits of his training, and he had exhausted himself to a point he had never thought he could reach. Training for hours and hours, fighting against thousands of clones, while constantly using Rasengans and wind chakra had left him feeling, for the first time in his life, low on chakra.

This was a hell of a feeling.

Naruto closed his eyes and went to sleep, satisfied with himself.

-Later-

"You see, that's your Daddy, the strongest man in the village."

Mizore carried Naruto on her back back towards her home, and since Naruto was asleep, she had to listen to all of the other girls who had already given birth to Naruto's children brag about him to their babies. The many Uzumaki children were showing remarkable vitality, and were stronger than the usual Yuki-onna children they birthed.

They were just born superior to any child they had bore from humans, or even the rare times they mixed their blood with other monsters. The resulting children had such strong vitality that it wasn't even a fair competition. Each and every child born to Naruto's genetics were amazing, geniuses who were developing at a faster rate.

The oldest of the children, a girl who was older than a year now, was already walking and using her ice powers.

Her ice powers that were stronger than a girl 5 years her senior, the children of Naruto were showing that they power houses in the making.

'The next generation of Yuki-onna is destined to be as strong, or stronger, than S-ranked monsters. That's the rumor going around... our population is experiencing a massive boom now... she just gave birth to her 2nd child, and she's already pregnant with her 3rd.' Mizore passed by a pregnant woman who was 22 years old now, and was pregnant with her third child of Narutos. At this point, almost every girl between the ages of 13 and 23 had, had at least one of Naruto's children at this point. In the village, she was the only young woman who hadn't accepted his seed.

Those who accepted Naruto's seed could get pregnant with powerful children, and since they gave birth, it meant when they turned 17 they wouldn't be forced to marry some random human man. It was their duty as Yuki-onna to fix their population crisis.

"Oh look at him, I heard him training even from my home, he was at it all night again."

"Of course he is, I mean, he's setting an excellent example for all these kids, hard working, helpful, kind, and so loving. He's the man of the village now."

'He is... he's like a miracle for us... it's too good to be true. We're all afraid that one day, he'll just... disappear. I don't think there is a single woman here who doesn't want him to stay in the village forever. Forever training himself, forever being a role model to his kids, and forever helping us.' Mizore knew how many of her fellow snow fairies were afraid of him one day just abandoning them, and going off to a place where they couldn't follow him.

He was so kind, so trusting, that when he was told the whisker marks on the children were just a side effect of the fertility drug (that was still in development) he believed them. Most of them actually felt bad for decieving him.

'He treats us all so kindly... he adjusted to our way of life, and unlike all the other men of the village who die from the cold eventually, his body has adjusted to us, and our way of life. We'll be able to grow old with him.' Mizore got to her home, and she passed by her mother making breakfast. She stopped by Naruto's room and dropped him off.

She could do it.

She could do him in his sleep right now, and she wanted to do that. She could sneak into his bed right now, take his tattered clothes off, and ride him until she was the first woman pregnant with a child that was born out of the act of love making. She could be the Yuki-onna who managed to have his true child, the one child born from sex.

'But he would hate me, hate us... he might forgive us for lying to him, but he would never forgive me for taking advantabe of him in his sleep... or maybe he would forgive us, maybe he would forgive all of us one day.' Mizore could understand everyone's fear, and the reason why they didn't tell him the truth.

Because, he really was too good to be true.

It was fear of Naruto disappearing that kept them all silent on the truth of where those children came from.

"I smell breakfast... time to eat already..." Naruto groaned when the smell of breakfast got to him, and even though he was exhausted not long ago, he still managed to get back to his feet. Mizore watched, and she saw that most of his wounds had already healed. His cuts were gone, and the bruises were half faded away already. Mere minutes ago, he had been too exhausted to stand on his own, and now he was walking under his own power again.

Naruto collapsed forward moments later.

"Nope, guess I need to keep napping... goodnight."

"It's morning."

"Good morning, time for bed." Naruto didn't miss a beat as he went back to sleep, and ignored the idea of going to eat.

Mizore dragged him back to bed.

"Good morning, have a good dream."
