I do not own naruto anime, manga or other released formats.
Naruto was not sure what to expect when he reached the village, but this was not it. This place looks like a regular village. Houses, businesses, hospital, an academy and even some people that look like regular humans, well if you discount that most people where wearing sandals and had no gloves, or the fact that they looked almost human. The almost came with their long hair, ears, and tails. He asked one of the people what it all looked so different. He was told it was a simple transformation and it made life in the village a lot more easier. He understood it, but it still shocked him. He had arrived at night and they had not posted any guards since they knew he was coming.
When he arrived to a massive cave opening, the person escorting him simply told him that it was the place the old sages preferred to live at. The transformation was not very popular with them. He went into the cavern and saw why, the halls were massive, and the way to get to everything require a lot of physical agility and strength. Little did he know that it was all planned this way. His training would require him to master his senses and grow in ways he never expected. As the hall he was told to walk down came to a massive cave it was clear that something was waiting for him, but it was dark all he could hear was some heavy breathing. Since he could not use his eyes he closed them and put both hands over his ears. His hearing improved a little but felt ridiculous, until he remembered his chakra. He lowered his hands and concentrated on using chakra on in his ears, immediately he hear what could not be mistaken. Three faint whispers from three elderly lady wolves was heard, "Well the student at the very least is not completely dumb!" said one on the right, "He was able to figure out he could not see, not bad for a pup." Said the one in the middle. "But he hasn't figured out if he used chakra in his eyes he would actually be able to see us!" Said the final voice on his left, clearly making fun of him.
He looked in that direction and smiled, "Or maybe he is just trying to respect your privacy while you are busy taking care of your paws." Naruto replied. This came as a shock to that wolf. How did he know that she was taking care of her paws. "Your tongue. I can hear it too." Naruto did not wait to be asked. The middle wolf hit a stone sending a spark in the air making a small pile of wood catch on fire. "At the very least he will be a lot of fun, we don't usually have much in the way of visitors. I am Kuna, my sisters are Kima on your right, and the one that was grooming her paws is Kuya my little sister. Glad to meet you Naruto Uchiha! Be most welcome to your least favorite training time I am sure." Naruto looked at her and simply had a look of confussion. Kima began to explain, "We three have devoted our entire lives to the training and practice of being sages. We chose to abandon village life, and even having a family to do this. The training will be some of the harshest you had. Most of our aspiring students end up quitting half way, and complain constantly. So that is why my sister may think you will not enjoy your training with us. Be at ease, and sit down. After you rest a little bit you will be told what you will have to do."
Naruto did sit down in a meditation stance, and told them he was just fine. "First of you will not be allowed to wear any clothes, except underwear. We respect some sense of modesty after all. The reason will be explained by Kuna as soon as you are done changing." Naruto did not question it, there must be a good reason. He took all his clothes except his underwear, but at the sight of his muscles Kuya was amazed. "So you done a decent amount of training, good." Kuya told him. "The reason why you will not wear more is because we expect you to use all your senses to train, To be a wolf sage means to train your senses to such that losing one will mean very little to you. To be in perfect unity with your senses is the basis of the wolf seinjutsu teachings. If you master our teachings you will be able to see in total darkness, hear miles away and tell the smell of a smallest flower from miles away. You will be able to see with nothing more than your feeling you will get from your sense of touch without touching anything at all. Strength will be trained naturally because everything in this cave weighs several hundred times normal, and agility will be trained because you will be asked to use the entire cave complex and not all of it is easy to reach. It would take at least 10 years for you to learn everything, but to have our mastery it would take you at lest 60 years of constant training. Do you have any questions?" Kuna was done talking and asked. "Just where am I supposed to sleep? and where is the bathroom? how do we get our food?" Naruto asked, Kiya began to laugh. "The place where you are seating is your bed, your bathroom you go outside, and food there is plenty of game to hunt in a nearby forest, also a small river where fish are plenty but be warned those fish as good size for use so you can imagine how big they are for you."
Naruto understood, he had to use his senses for everything here. "Can I use shadow clones?" Kima answered that one, "Only for practice, you must learn to do it yourself first. For everything else no clones. We don't waste chakra on things we should be able to do alone."
Naruto understood that these sages were going to be very strict. Everything had a purpose and he would need to learn fast, and efficiently. He did not have 10 years, and being away from Mikoto for a decade would drive him insane with worry. How was he to know that Mikoto felt exactly the same. Her life would also be difficult as he too tried to train her doujutsu and tried at the same time to stay away from the constant pest she came to hate so much, a pest named Fugaku. Not the name he would call him, he would call him the putrid tick of Konoha, he was a wretched creature that was very unpleasant to her, and was very hard to get rid of.
The three sages were surprised to see that the physical requirements of the training were nothing to him. The hunting and living came to him as natural as breathing. His big sis did tell him many things about proper fox behavior and hunting techniques. Kiya much to the discomfort of her sisters even made a bad joke about him. She told her two sisters that if she was at lot younger she would want to pick him up for herself. She told them she was just a delight to the senses. Her sister Kima told her to and concentrate on her teaching, and Kuna told her to stop acting like a teenager in heat. Life in the lonely cave was sure becoming more and more interesting.
The one technique that seemed to be a true gift from the heavens, had been the shadow clone. He did as he was told as soon as he was able to pass one test, he made a thousand shadow clones to master it. The three sages could hardly believe it, at the rate he was going he was going to have more mastery of the sage arts than then in 10 years. But when life is only focused on learning, training and living time tended to go a lot faster. The 10 years had changed Naruto a lot, he looked so much like his grandfather. His muscles, and high were impressive. New underwear was brought to him every 2 years by the village ninja. One of the anbu made a surprise statement as she left that the human was quite the hunk, maybe she needed to try and getting him for herself. The three sages and Naruto heard her from a few hundred feet away. "Boy that girl sure is going to be sad, you haven't told anyone about your mate have you pup?" Kima asked him. He simply used a Katon Jutsu to finish cooking his boar. "No, why should I? I came to train not to full around."
Kuna just agreed with a nod, "Something my little sister is still having trouble learning it seems." Both Kima and Kuna began to laugh. Kiya was too busy sulking."So what if she liked to play sometimes, she was still quite frisky for her age. Kiya just enjoyed the company of some men, what was wrong with that. She took all necessary precautions after all.
10 years and came and the training could not progress anymore. The villagers looked at him get out of the cave a changed man. They were going to miss their jokes about the three sages being lonely without him around. The sages did not comment because that was true. Naruto had made their lives seem more peaceful, fun, and comfortable. Some of the kids now teenagers joked that Naruto should be called the village's 4th sage. Fenrir was told of his progress and he was proud of the clan summoner. Many wolves consider him a fellow villager.
Fenrir knew that he needed to provide new clothes and so he secretly asked Mikoto to prepare some. What she sent was a perfect copy of what Madara Uchiha had worn last as a ninja of Konoha. The only difference was the sizes. As Naruto dressed himself, and thanked the sages for their training and hospitality. They of course could hear him from the center of the village. The three sister had smiled at his kind gesture. "It is time to go Naruto, I wonder how you mate will find the knew you." Said Fenrir as he took Naruto back to Konoha.
As Naruto appeared he was greeted by a shorter Mikoto, he looked surprised. She was not shorter she told him seeing his look, he was just taller. Without waiting for his approval she hugged him, "I sure missed you Naruto you really must tell me what you have done since you been away this entire month." That statement made Fenrir disappear laughing as he saw the wolf clan summoner on the ground having fainted. I guess he forgot to tell him that time was different on their village that any where he could imagined. Mikoto and Kagami took Naruto to bed and she did the most scandalous thing she ever had done. She removed all of his clothes, and hers as well and climbed into bed with him. When Naruto wakes up the look on his face will be priceless, Mikoto believed as she fell asleep in his arms. Fugaku had come to look for Mikoto for the thousandth time. He found her sleeping with Naruto in the same bed. The look on his face could not help to hide the sheer rage he was feeling. Brother my eye, they look like a couple of newlyweds. Fugaku was thinking as he ran way to his home.
