Chapter 1

Limitation

It had been six years since the Kyūbi attack and because of Madara's actions, one little boys life had been turned upside down. Naruto Uzumaki was a child that only 10% of the village knew existed and even less than one percent had ever seen him. It wasn't just because everyone's attention was on his twin sister, who everyone tried to become friends with and occasionally tried to get marriage proposals for. Something more saddening happened on the night of the Kyūbi attack. Instead of using the Shiki Fūjin to seal the Kyūbi away, Minato used a different seal to split the fox's power in half. He knew that without the Kyūbi's chakra, Kushina wouldn't have long to live. But if he chose to seal all of the Kyūbi's chakra back inside her, in her weakened condition, her body wouldn't be able to handle it. So he sealed the Yin inside Kushina and the Yang inside their newborn daughter Mai.

It wasn't until a few days later that Minato and Kushina found out that there was something wrong with Naruto. Because Naruto's body had been inside Kushina's womb for the past ten months, the doctors had found out that his body had become reliant on the Kyūbi's chakra. Mai would have suffered the same fate if the Kyūbi's yang chakra had not been sealed inside her. When growing up, he would become heavily fatigued just after walking five minuets, his immune system was pathetically low; which is why he mostly stayed home in bed to catch minimal diseases, his body would only produce just enough chakra for him to live, and he didn't learn how to walk until he was four because his muscles could hardly ever put to good use.

When Naruto thought of his family, he couldn't help feeling sorry for them and yet, loathe them. He felt somewhere deep-down inside of him, his crippled body was a constant reminder to his family of what happened six years ago and that they'd be happy if he died. It was mostly jealousy that made Naruto hate his sister. On their birthday, while Mai got practise kunai and many other thing off their friends and family for when she joined the academy, Naruto mostly only got books (which were probably for a three year old) and clothes, while Naruto understood that they didn't get him the things his sister got because of his condition and his sisters popularity, he couldn't stop the emotional pain he was feeling. Why did he have to suffer like this? What deity would be cruel enough to make him watch day by day, as his sister lived the exact opposite life he did?

There were benefits to his condition. For his week body, he attained a strong mind. His learning skill were off the charts, his mind soaked up everything he read day and night. He had developed a photographic memory that would allow him to keep any good information he knew and would remember it instantly. He had his own little library in his room, filled with the latest edition books and scrolls of other villages and forbidden knowledge on human anatomy and chakra. While it could called legendary if you ever saw him leave the house, Naruto had left minimal times to find any information that could help him cure his condition. The forbidden items he had were from the underground market,who only by chance, did he manage to get into contact with them. Plus his fathers secret vault room, where many Konoha secrets were kept.

There were three names that came from three specific scroll in Naruto's room. Tsunade, Orochimaru and Hiruko. Naruto dived deep into their research that saw classified, twisting it to his own use for ways to gain the ability to become stronger. While Konoha would never admit it, there were certain valuable documents they gained from Orochimaru and Hiruko's work. He even made copies of his father sealing scrolls to learn from and began to test one specific seal. Naruto got away with this because his Mother and father were too ignorant of his doings because either Mai almost had their constant attention or they found no harm in letting Naruto read the sealing scrolls, seeing as Naruto had only enough chakra to live, yet alone put it into a seal. That was true but, Naruto scraped the barest amount and stored in the centre of his chest, continuing to do so for months. Eventually, he pored the chakra from his chest to the seal on his left arm and activating it, creating his first chakra absorbing seal. Using it strait away to absorb the chakra from the air in Konoha, mostly from people who used too much chakra in a jutsu. The seal itself only stored chakra into one of the six storage parts, allowing non of the specific chakra he absorbed, to mix with each other, apart from the first one.

Naruto knew what was the cause of his condition and why his twin sister didn't have it, living in the same house with the people involved helped him figure it out. Naruto's very first plan was to seal a small portion of Kyūbi's chakra he had collected from the battle sight into himself, in a similar manor of his sister had, to cure him as it did his sister. Further study of Tsunade's scroll suggested that to even attempting that would probably kill him. With his body in a weak state, the violent chakra would destroy him from the inside-out. Even if he didn't die, the amount of time Naruto had been apart from Kyūbi's chakra meant that it wouldn't fix his condition anyway. At this point, Naruto read through Hiruko's research on ways force ones body to adapt and changes. He went form reading about mixing animal body parts, to bloodlines and finally, different chakra nature. He had gone through many theory's on the problem and all of them would even kill his sister, that's when he turned to Orochimaru's research. The problem wasn't that his theory would kill him strait away, it was the amount of time his body needed to adapt to the change. Orochimaru's methods to prolonged life (I'm not talking about his immortality jutsu) were only minor useful but all of them involved having a strong body to begin with.

Just when Naruto was about to give up, he discovered a particular book that might just answer all his problems. The book itself was extremely rare and even if you did read it, you'd probably think of it as some sort of fairy-tail. That was how Naruto got the book in the first place, he received it on his birthday as a present from one of his mother or fathers friends. He cross-referenced the book with all myths and legends Konoha knew and discovered some traces of compatible parts with the book. Naruto couldn't help but think of the reason that drove him so hard to find a cure in the first place.

(Flashback)

It had been a month since Naruto's fifth birthday and he had just come back from the hospital, from his monthly check-up. It had become midnight and Naruto had just come from the bathroom. He was just about to go to his own room when he heard crying coming from his parents bedroom. Slowly approaching the door, Naruto leaned his head against it to find out the problem.

In the room, Minato had Kushina held tightly against his chest. Earlier that day, they had received the best and bad news a parent can ever hear. The good news was that there was going to be a new member to their family. When Kushina heard she was pregnant, she thought nothing could upset her mood today. Then there came the fates bitch slap. It seemed that if the Namikaze wanted to receive a new member into their clan, they must loose one as well. The doctors determined that Naruto's body was fighting a loosing battle to live and they gave him about four years to live.

"Why does this always happen to us? What did we do to deserve this?" Cried Kushina as she held onto Minato, as if he was also going to disappear.

Minato just kept rubbing Kushina's back, trying sooth her emotional pain. "I know hime, I Know. We have to stay strong for Naruto." Said Minato trying to hide his own tears.

"It just isn't fair. He's already lost the ability to have a normal childhood, why does he have to loose his life?" Mumbled Kushina, as more tears came pouring out.

She gently put her right hand down and touched her belly, a look of horror on her face unwilling to come off.

MINATO! Won't our baby be just like Naruto? Without the Kyūbi's chakra it'll suffer, just like Naruto has!" shouted Kushina, looking into Minato's eyes.

Minato brought her head up and kissed her lips. "There's nothing to worry about. The seal I put on you and Mai is more stronger that your old one. Plus, now that the Kyūbi's power is split in half, the Kyūbi's influence won't be able to affect the baby at all. All we can do for Naruto now, is make his last four years on earth as comfortable as possible."

Naruto felt a part of him die there and then. As if the artificial world his mother and father built around him crumble, shoving the reality of life in his face. When he thought of it, he let out a hollow chuckle as he shut his bedroom door. Naruto understood that the world was a cruel place. But to experience one of it's cruelties and die from it, at a young age left him empty. That night, Naruto cried himself for hours, cursing fates name. (not sure how exactly.)

(End flashback)

Naruto snapped out of his thoughts and began checking out his equipment to begin phase one of his plan, smiling at the small glimmer of hope he had for his plan becoming a success.
