Chapter 1

Lycanthrope, it is a rare disease that allows a person to transform, occasionally unwillingly, into a hybrid beast, most common is a werewolf. This disease is only transmitted by an animal of certain properties.

The animal must posses a certain gene and that animal has to bite a person during a full moon. When inflicted with lycanthrope, a person will gain vast amounts of strength and his/her stamina would almost triple in quantity. His/Her reflexes would be faster and that person's instincts and senses would be sharper, including the person's memory.

There would be a slight change of physical appearance, muscles will develop rapidly without the bulge of a body builders and the victim would look more feral. When in hybrid form, the victim would about seven to up to eight feet tall, this is determined by age and gender of victim. The victims fur color would be unknown as the fur is different from every victim, but a theory is that the fur is reflected of their hair or probably personality (will need further study). The size of the victim in full animal form would range from a Lioness up to a mature horse when adolescent or adult and pup to normal wolf size.

However, when someone is infected with lycanthrope, he/she would transform underneath a full moon. If trained properly, the victim/patient would be able to transform by will either to his/her hybrid form or full animal form. But the patient would still suffer from the forced transformation of the full moon.

During full moons, the victim (if not strong willed, properly trained or due to some other reason) would lose almost all sense of sanity and will not be able to distinguish friend from foe. Most cases are that the victim would become feral and would lose all sanity and become an animal of the forest.

Though true lycanthrope, where one is bitten by an animal, is rare. A victim of the disease could spread it to others if he/she bit another person in either hybrid or full animal state.

This would be second hand lycanthrope, a victim of this would gain all effects of lycanthrope except that he/she would become insane at the first full moon regardless of training or will.

Patients (both of true and secondary lycanthrope) would show some animal traits, like searching for a mate, to fight over possible mates and to care for his/her family/pack/cluster etc. Though that would difficult to say as human being is capable of emotions, unlike animals that don't have any emotions at all.

Although these are what would happen if someone is inflicted with lycanthrope, there could be other effects, it will depend on the victim him/herself. More thorough study on victims/patients, and the animals if possible, is needed so we can learn more of this disease.

Sandaime Hokage sighed as placed down the scroll he was reading. It was a very old scroll, before the time Konoha was founded. Sarutobi had just found it by accident when he was sifting through the Hokage's personal library.

The scroll had some interesting information on a rare disease which seemed to be related to that of the Inuzuka Clan traits.

The third took out his patented crystal ball and started to view on the Fourth Hokage's legacy, Uzumaki Naruto. Sarutobi's crystal ball just viewed the eight year old child eating his heart out in the Ichiraku ramen bar.

"Seems like everything is okay." Sarutobi mumbled as he stopped his viewing and yawned. It was getting pretty late and an old man, even if he's Hokage, still needs his rest. Looking out the window in his office he saw that there wasn't a cloud in the night sky and that the moon was full.

'Funny, the conditions of tonight suit that of which the scroll stated.' Sarutobi shook that thought away. He was too tired to think and a scroll that was way old depicting about some ancient illness was just too tiring to think about.

Grabbing the scroll he had been reading on his desk. Sarutobi went to his secretary and handed her the scroll. "Please file that scroll for me. Would you?" Sarutobi asked. The secretary nodded "Hai Hokage-same. Have good night's rest." She said respectfully while bowing her head.

Sarutobi returned the bow before leaving the Hokage tower and to his home.

At the Ichiraku ramen bar, Naruto had just emptied his fifteenth bowl of ramen. After slurping up the delicious delicacy, he paid the owner before heading home.

"Goodnight Ichirakuji-san, Ayame-chan. Thanks for the food" Naruto said before leaving the leaving the ramen bar. Teuchi Ichiraku and his daughter waved goodbye to their number one customer of Konoha as they started closing up shop.

As Naruto walked home to his apartment he decided to take a little shortcut through the park as it would make a direct way home. As Naruto entered the foreboding looking area, he felt the hair on the back of his neck stand on end.

The Kyuubi vessel felt as if someone or something was watching him. As walked deeper into the park, Naruto kept on hearing the rustling of nearby foliage. The blonde boy was starting to get frightened.

Naruto started to walk a little bit faster. As he did, the rustling stopped, only to be replaced by the sounds of following steps. As Naruto broke into a run so did his follower, the foliage in the park was dense so Naruto couldn't get enough light from the moon to see where he was going. So in one fluid grace, he went in random directions in hopes of not meeting who or whatever was following him.

That hope was dashed immediately when Naruto found himself in front of a dead end. The following footsteps stopped and the Kyuubi vessel heard low growling coming from behind. Naruto turned around slowly and found himself face to face with an enormous wolf.

The wolf was the size of a horse. The fur on its body was covered in blood with only a few places of white fur. Its eyes are yellow but depicted rage that Naruto usually saw with most of the adults. The wolf's tail was standing up straight and its back was hunched

And it showed an impressive mouth of incisors.

Naruto kept glued to his spot, not moving an inch, too afraid of the growling wolf to move away. As the wolf charged was the only time when Naruto regained the feeling in his legs and was lucky enough to roll out of the way of the charge.

When Naruto fell flat on his face, he tried to get up on his two feet, only to feel searing pain on his right shoulder and a huge weight on his back. The wolf was on top of the boy's back, with its teeth sinking in to the child's right shoulder.

Naruto's eyesight started getting cloudy due to the amount of blood loss. As Naruto drop to the ground and started to drift to unconsciousness, he saw the blurry form of the wolf turning into chakra and entering him.

Break

Inside of Naruto's mind, the Kyuubi no Kitsune stirred within his seal, feeling another presence entering his vessel. As the great fox demon opened an eye to see a giant shadow in front of him. The shadow was the shape of a wolf and equaled him in size. His cage had enlarged as well as if accommodating the two beings.

The Kyuubi's chakra was mingling the wolf's. "Interesting, so a child of the moon has bitten my vessel." The fox said as he stood up and faced of the shadow. "Let's see how strong you are." The fox demon said as it charged at the wolf.

The wolf, seeing the attacked, phased through the bars caging Kyuubi. This shocked the fox that he had no time to stop himself from banging on the gate. "So you will have a greater effect on our vessel huh" Kyuubi said as he looked at the wolf, who nodded in reply.

Kyuubi moved away from the gate and curled to continue sleeping, no use of getting angry. He was sealed in this vessel till the child would die thanks to the fourth hokage. But thanks to the bite of the wolf, his containers life span would almost double no triple now or maybe even become immortal.

The Kyuubi snickered as he thought about it, the Yondaime never thought that his legacy would turn out like this, but the Kyuubi knew that now that his container was bitten he would have to help train the boy to help control his lycanthropic ability.

He would also have to share his chakra and teachings to the boy's future mate as all well as lycanthropic victims would always share a mind link and energy link with each others mate. Kyuubi would worry about that when it would come, but he had to find a way to train his container or risk having the child run amuck and getting captured or killed and in turn getting himself killed should that ever happen.

As Kyuubi was about to back to sleep, he felt his containers presence. He turned around to see the blonde haired boy looking at him through the cage. Kyuubi looked around and saw the wolf shadow next to him.

'Well, the earlier the better I guess' Kyuubi thought as he and his new 'roommate moved closer to the gate to inspect the boy.

Break

Naruto found himself in some sort of sewer, as he felt that his feet were wet. 'Where am I wasn't I in the park? And where's that wolf?' these thoughts were traveling in the young six year old's mind as trudged through the waters and came across a huge barred gate with a paper with the Kanji for 'seal' written on it stuck on the gate.

Red and black chakra was emanating from the gate. Naruto backed away in fear saw two sets of eyes staring at him. The first set, were red and the pupils were slitted. While the second set was blue.

Two figures came closer to the gate and Naruto got a better look of who or what was inside. Naruto saw a huge red-orange fox with nine tails, he saw tendrils of red chakra and waves of killing intent and hatred yet had a sense of mischief and playfulness coming of the beast.

The second figure was an equally huge wolf. Naruto couldn't see any detail of the wolf's body, like the body was just a shadow. Naruto felt a wave serenity and ferociousness coming of the wolf.

Naruto started to back away from the two beasts, only for the wolf to pass through the bars and reappear behind Naruto. The child looked over his shoulder to see the giant wolf looming over him without the gate to separate him from the beast.

The wolf slowly bent its head and pushed Naruto towards the gate with its muzzle. When Naruto was in front of the fox, the wolf passed through the bars once again and stood near its cellmate. Naruto gulped when he saw the fox smile wickedly at him.

Break

Naruto sat deep in thought in front of the cage, the fox, or Kyuubi as he learned from it, and the wolf observing the boy. Naruto was shocked at what the fox had told him.

Flashback

"Y-You're the Kyuubi, but we were told that the Yondaime died while killing you years ago."

The Kyuubi snorted "Your fourth hokage was too weak to kill me, so he opted to seal me instead. Why did you think the adults in your village despised you? They only saw you as me and not the hero as the yondaime had hoped. Humans are so disgusting, at least we don't treat our companions that way." Kyuubi said the last part in whisper so as not for Naruto to hear it.

"But, why…why did he decide to seal you in me?" Naruto asked sadly not looking at the fox. "The fourth couldn't seal me in an animal as my spirit was too great. He could not seal me in a body that of an adult as an adults chakra coils were to developed to contain me. So he decided for a newborn child, his own flesh and blood"

Naruto looked up with a surprised look on his face "The yondaime was my father!" The Kyuubi nodded as he spared a glance at the other tenant who was sitting there motionless and looking at the boy.

"Yes, the yondaime was your father, he wouldn't allow himself to ask someone to give up their child to be my container. So your father sealed me in you using Shiki Fuujin, but in the process, lost his life to the jutsu. While your mother died while giving birth to you."

Kyuubi stopped for a while for the information to sink into the boy's head before continuing.

"Kit, you have a problem…."Kyuubi was interrupted by Naruto "No kidding! I have the Kyuubi sealed inside me! And my dads the Yondaime! Why wasn't I told!"

Naruto's rant was cut short when Kyuubi roared which pretty much stopped the hyperactive blonde.

"Kit! I don't know the reason why nobody told you who your father was! If you want you can ask the old man hokage later! But for now listen to what I have to say!"

Naruto nodded rapidly, intimidated by the Kyuubi.

"You've been given the gift of shape shifting, but you have to train your mind, body and spirit before your first transformation. If you don't then you'll go insane and will probably end up killing everyone in sight until everyone is dead or until someone knocks you out or kills you. So I will have no choice, I will have to oversee your training."

This brightened up Naruto quite a lot, learning from a powerful and very old demon, he could learn a lot of jutsus. Then Naruto looked at the wolf, which was still looking at the boy.

"What about him?" Naruto asked indicating to the wolf. Kyuubi looked at the wolf then back to his vessel. "He's the spirit of the wolf, his energy is mingling with yours. Once the first full moon occurs he will be more active, but for now he's just dormant."

Naruto nodded, although he understood only a little of what the Kyuubi said.

End of Flashback

"So when will my training start…Kyuubi-sensei?" Kyuubi smiled wickedly once more before answering. "RIGHT NOW!"

Break

As Naruto dropped dead on his bed, his mind had started to summarize the days event. Kyuubi had woken up Naruto at six o clock in the morning. Had Naruto do a gravity increasing jutsu which increased gravity to match his strength, which was a ten times the normal gravity on his body. And every time he would increase his strength, the jutsu would increase the gravity until he dispelled it.

This would make it impossible to move but having Kyuubi's stamina, and stronger muscles and other changes because of the bite and Naruto's persistence he was able to move and do all of Kyuubi's exercises.

Kyuubi had told him to run fifty laps around Konoha, five hundred sit-ups, push-ups, chin-ups, abdominal crunches, fifty laps swimming around a fifty meter in diameter lake and doing the previous exercises two more times. To top it all of, Naruto was only allowed to eat ramen once day, preferably during Lunch. The rest of his meals he was going to eat, vegetables and other produce.

"Stupid fox sadist." Naruto mumbled before falling asleep not hearing the Kyuubi.

"Don't worry kit, by the time I'm through training you, you will be Hokage for sure." With that, the Kyuubi joined his vessel and cellmate in sleep.

The next day, Naruto woke before dawn, thanks to Kyuubi and repeated his training. When he finished his swimming and was cooling his body down, Naruto heard Kyuubi speak. "Kit, I'll be teaching you how to do water walking. This exercise will help you to mold chakra and improve your chakra control. Improving your chakra control will allow you to do more jutsus as you will not put too much chakra when doing one."

Naruto nodded and continued to listen to his new instructor. "First, I want you mold chakra to your feet. Then, when you think you've placed enough chakra on your feet I want you to walk on the water's surface. When you get this exercise right I want you to continue until you can do water walking without any problems at all. Then practice this on your other body part like your hands, knees etc."

Naruto nodded, he stood up and concentrated his chakra on his feet. After putting what he thought was sufficient chakra he placed one foot on the water's surface. He was happy that his foot was being supported. Feeling confident, he placed his other foot on the water's surface and was still being supported.

Now sure he was able to do it he started to walk along the edge of the lake, to make sure he could get to dry land quickly if anything would happen. And something did happen, Naruto felt a tingling sensation all over his body, then the gravity on his body increased even further and before he could do anything, Naruto was struggling to keep himself from drowning.

When he thought he was goner, a hand grabbed his own pulled him onto land. Naruto coughed up some water and looked at the person who saved him. It was a boy a year older than him, with large round eyes and very thick eyebrows. He wore his hair in a ponytail which reached three-fourths of the way down his back. He wore a white Chinese shirt, black pants and blue shinobi sandals.

"Daijoubu desu ka?" the boy asked. Naruto nodded before coughing up a few times. "Hai" Naruto replied as the thick browed boy helped him up. "Watashiwa, Rock Lee, dozo yoroshikun." The boy said with bow while introducing himself.

Naruto returned the bow, very happy not that the boy helped him, but because he did not give cold eyes that most people would give him. "Arigato Lee-san, Uzumaki Naruto." He said with a fox grin.

"Your welcome Naruto, but just call me Lee." Lee said returning the smile. "By the way, why were you drowning?" Lee asked the blonde. Naruto scratched the back of his head in embarrassment. "Well you see, I was training. I was practicing water walking but after a few steps I started to sink because I forgot about my weights and well.. you know the rest."

"Well, I have to go back to my training, maybe we can spar the next time we meet. See you later Lee" Naruto said before running out of the clearing. Lee waved back before he thought of something. 'How did he know I was training to be a ninja? Oh well back to running.'

While Naruto was running, he decided to go get some lunch. "Hey, Kyuubi-sensei, what happened back there, why did the gravity increase all of a sudden?" "It seems that a full moon is closer than I thought. The wolf has already started increasing your strength, your muscles developed quite rapidly that's why felt something happening to your body."

"So what are we going to do?" "We'll have to speed up your training, from what I could remember you have to be strong willed to tame yourself."

'No problem there' Naruto and Kyuubi thought at the same time "You'll have to develop your body to withstand your transformation." "That's all I have to do?"

"That's all, and you better watch where you're going." "Huh?"

Naruto was so deep in conversation with Kyuubi that he crashed face first into a metal pole. After checking that his nose was alright, he looked around and found himself in the park. He saw a giggling girl sitting on a swing.

The girl is about Naruto's age, with lavender hair, pale white eyes, creamy white skin and was wearing a pink kimono with sakura petals on it. Naruto looked sheepish, and when the girl stopped giggling, she looked embarrassed and started to stutter. "Go-Gomen, I-I didn't mean to la-laugh at you."

Naruto gave her a fox grin "Its okay, serves me right, I should've watched where I was going anyway." The girl blushed, then Naruto introduced himself "My name's Uzumaki Naruto, nice to meet 'cha."

"I'm Hy-Hyuuga Hinata, nice t-to meet you Naruto-kun." She said shyly. Naruto smiled at her as he met another person who didn't give him hateful glares or told him to go away.

"Hinata-chan, would you like to eat some ramen with me for lunch?" the blonde boy asked.

Hinata looked a bit sad for a moment "Naruto-kun, I-I was told not to leave the park." She said sadly that she couldn't enjoy a meal with her new friend. Naruto nodded and decided to sit on the swing beside the girl 'I'll eat some food later. Food can always wait. Besides Hinata-chan is different from most people, she doesn't hate me or tells me to go away.' Naruto thought as he looked at the girl who was surprised at what he did.

"It's okay Hinata-chan, I'll stay with you until someone picks you up." He said cheerfully as he started playing on the swing a little. "A-Are you sure?" she asked slightly guilty that she was making her friend miss lunch just because she couldn't leave the park.

Naruto nodded "Yeah, I'm sure, besides food can wait." Hinata blushed and the two children started to play. Kyuubi looked from the inside of the boy's mind and decided to leave the boy alone to play with his new companion, besides, he could make up for the lost training by doubling what he was going to do later. The fox snickered and then looked at his cellmate.

The wolf had phased through the bars again and darted to another part of Naruto's mind. Kyuubi wondered what was going on when the wolf came back a few minutes later. 'Wonder where he went?' Kyuubi thought before he returned to watching Naruto.

Hinata and Naruto played until two o clock in the afternoon. While they were playing a man, who had the same eyes as Hinata arrived.

He wore a white robe (kimono?) with matching socks and a pair of sandals. His hair is black and was quite long and reached the man's upper back. "Hinata, it's time to go home" the man called. Hinata looked happy and ran to the man, who kneeled down and hugged her. "Otousan!"

As the two were about to leave, Hinata turned around and waved back to Naruto "Bye Naruto, thanks for playing with me, I'll see you again." Naruto waved back wordlessly smiling at the girl.

Hyuuga Hiashi's thought remained on the boy with whom his daughter played with. He noticed that Hinata did not look so shy and did not stuttered when she was with the boy.

'People might see him as the demon but some of us know better. Hinata you may have just met someone special.' Hiashi thought as he and his daughter went home

Break

After Naruto ate his meal of ramen, he went back to training. While training, his thoughts drifted back to Hinata. He felt warm inside while seeing her smile, but that feeling was short lived when he felt an all too familiar tingling sensation all over his body. Naruto ate dirt as his gravity increased again.

'Kuso, this really stinks, how can I train properly if I keep getting stronger that the gravity just keeps increasing?'

Kyuubi didn't reply, Naruto just heard a loud snore. 'Baka Kitsune!' Naruto sighed as he went back to the lake to try and to water walk again. After a few more hours of doing water walking, Naruto was able to get himself used to it and was able to do it using every part of his body. He was even able to recover quickly during every gravity increase.

As Naruto was taking a rest he heard Kyuubi talking to him. "Alright kit, you did well. Now I want you to run around the lake's surface one hundred times, one thousand sit-ups, push-ups, squats, crunches and everything else while water walking, then you can get some dinner and rest." 'NNAAAANNIIII? HOW AM I GOING TO PULL THAT OFF!' Naruto yelled mentally. Kyuubi just shrugged "Your fault, you wasted some time playing with your girlfriend, so now your going to make up for it."

As Kyuubi laughed within his mind, Naruto blushed about Hinata and himself being like that. Besides they're only six years old, there's no way they can be in a relationship could they? "Sadist." Naruto muttered as he did the exercises he was told to do.

Author's Note:

That's the end for chapter one, hoped you liked it. Please review some suggestions to help build my story. I'm new so any advice would be welcomed.

I know that Hiashi is a bit OC, but I think that's why he acted, to act cruel to his daughter to build her self-confidence and strength through rebellion or self-reliance.
