PROLOGUE

"Lily, grab Harry and go! I'll hold him off as long as I can!" James Potter shouted to his stunned wife as he prepare himself to do battle with the Dark Lord himself, who was blasting his way through Godric Hollow's magical defenses like a hot knife through melted butter. He knew that they were betrayed. It was the only explanation how Voldemort managed to find them despite the Confundus Charm set on their home. "LILY!" shouted James once more just before the front door was blasted open and Voldemort walked in. That had got Lily out of her horrified stupor and had her running upstairs. Lily burst through her son's room and saw Harry crying in his crib, as if he knew that danger they find themselves at the moment. Using her wand, she cast the most powerful locking charm she knew at the door in hopes of at least delaying the Dark Lord long enough for her to cast a spell, or rather a technique she never thought she would ever use during her lifetime. "Dear Lord above, please let this work!" She bit her thumb and dropped into the floor. She started writing several symbols with her blood before placing her hand in the middle of the group of symbols. She poured out all her inner energy and uttered the words, "Divine Guardian Beast of my clan, I call upon your powers. Come forth and help those you have found worthy of your protection. Heed my call, for I am Lily Evans, also known as Hanzo Yuriko of the Hanzo Clan offer my life in exchange for that of my son, Harry Potter no Hanzo. KUCHIYOSE NO JUTSU! KYUUBI NO KITSUNE!"

She saw the symbols glow into a radiant red before tendril of reddish mist begun rising up from the said symbols. It traveled up her hands and surrounded her body. But then, something suddenly went wrong, the symbols on the floor begun to break, only to form into a different symbol, and then blue mists started rising up from the said new symbols.

Then, the entire world turned black and white. Sounds of any kind had disappeared as well. It's like the entire universe was suddenly frozen in time. "W-what's going on?" she said in a panic.

Then, the blue mist begun to take shape in front of her. It didn't take long for the blue mist to take a form of a man. When the mist faded, there stood a man who seems to be in his late twenties. He has spiky blond hair, deep blue eyes, and wearing some kind of ninja outfit of intricate designs.

"W-who are you?" Lily asked.

"Please do not be afraid, Lily Evans, or should I say Hanzo Yuriko. My name is Kazama Arashi, vassal to the Shinigami." The man said with a warm smile that slightly took away her fear.

"The Death God? But why are you here? Where is my family's guardian beast? What happened to the Kyuubi no Kitsune?"

"I am sorry to inform you, Yuriko-san, that the Kyuubi no Kitsune will not be able to come. As of the moment, he is a victim of circumstances, and is currently unable to offer his assistance to you."

"Why? What happened? I cannot save my son without him."

"For the moment, I am not allowed to tell you of what had happened to him. I am here to offer you a deal, the same one you were about to enter with the Nine Tails. Your life for your son. Do you still wish to proceed?"

At this, Lily stared hard at him and said, "Yes."

Arashi looked at her sadly and said, "Very well. Once time starts again, situations would occur that would lead you to your death. The Death God himself would come to protect your son and soon he would also become a Child of Fate."

Lily could only nod sadly at her own fate and said, "Thank you." Before Arashi was able to leave, Lily added in a small voice, "W-will my son be all right after I'm gone? I mean, such are the burdens to be a Child of Fate."

For a moment, Arashi merely stood there not saying anything. Then, he turned to her and gave her a sad smile before saying, "I was on a same boat as you once. I was forced to give my life to save my precious people, and in the process, I had given my own son such a heavy burden that could either destroy him or make him the most powerful being alive. He would have a rough life ahead of him and I won't be able to do a damn thing about it. The only thing I could do is believe that he would grow strong enough to carry the responsibility Fate had given him."

"I-I understand. Again, Thank you, Arashi-san." Lily said before time resumed its flow.

The door to the room was blasted open, and Lily used her own body to shield Harry from the debris of wood.

Voldemort strode in like death himself and regarded the woman standing protectively in front of the crib. "Foolish woman. Do you think you could stand against the most powerful Dark Lord of the century? Stand aside, girl."

"No!" She shouted as she raised her wand. "I will not allow you to harm him. You shall not kill my son!"

"Very well, mudblood. AVADA KEDABRA!" And Lily Evan Potter, also known as Hanzo Yuriko, died before she hit the floor.

Then, the Dark Lord turned his wand at the crying child and uttered the killing curse, only to rebound back to him.

That night, Voldemort's body was destroyed and Harry James Potter received a lightning bolt shape scar on his forehead. But unknown to everyone else, another miracle had occurred. For a brief moment, intricately woven seal with a spiral in the middle appeared on the child's stomach before disappearing altogether.

In a dark cold place, a tremendously powerful being known as the Kyuubi no Kitsune was restless. He is a guardian beast, his duty to protect is an utmost importance. But how can he when he is trapped in this desolated place where escape is impossible?

The green eyed child is in danger. As the last of his clan, he must protect him at all cost or else he would seize to exist, for that is the fate of a guardian beast who fails to protect their clan.

Centuries ago, he was a mere minor demon plaguing the lands. He was powerful compared to humans but in the demon world he was a scavenger, never having the ability to grow stronger so he was a mere annoyance to the greater demons. But when an ancestor of the Hanzo Clan had fought him and won, he was given a choice of either oblivion or servitude to the clan. When he chose servitude, he was granted a chance to become strong as long as he continued to protect the Hanzo Clan. And get stronger he did. In only a couple of decades, he managed to earn his tails through hard work, determination, and unrelenting will to be the most powerful, which eventually turned him into the most powerful of the Tailed Beasts, the Kyuubi no Kitsune.

Now, if the last of the Hanzo Clan dies, he will lose all the power he had fought so hard for. Once that happens, the demon world would be in such an uproar to gain his position and he would be the target of every major and minor demons throughout the planes of existence. He could not let such a thing to happen. He must find a way to protect him or he would face a fate worse than a thousand deaths.

Then, it hit him. If he could connect his vessel's subconscious with that of his charge, then he might be able to provide the green-eyed boy with the training needed to keep himself alive long enough before he can get to him. Using himself as the medium for both his charge's and his vessel's soul, the two Child of Fate would be able to see the other's life. Once that is done, the Kyuubi would provide his vessel with skills that his charge could learn as well through the said vessel. He would also subtly give them a little push to get them to master those skills to keep them alive. It would be like training two people at once.

With his plan made up, the Kyuubi no Kitsune brought out everything he had to connect two souls together, making sure nothing would be able to cut or invade such a connection of the two to ensure his continuous existence in the seat of power.

In another world, a one year old blond haired baby was sleeping peacefully on his crib when his eyes suddenly burst open. His usual bright blue eyes now slitted red and a lightning bolt scar appeared on his forehead before both disappeared once again. It also caused the child to wail, waking the old man in the next room.

Sarutobi, the Sandaime Hokage of Konohagakure, entered the room and picked up the child in his arms before rocking him to sleep. Soon enough, the child stopped wailing and closed his eyes. Sarutobi placed the child in the crib once more before softly uttering his name with a warm smile in his face, "Sleep well, Naruto-kun."

CHAPTER 1

-----Naruto's World-----

Six years old Uzumaki Naruto was running and he dare not stop. If he did, those people that were chasing him would surely beat him up. He really wasn't planning on going to the Festival but he had no choice. He hasn't eaten for over a week now. If only he hadn't accidentally bumped into those drunken men he could have gotten home and hide for the rest of the week but it seems luck was not on his side.

He took a quick glanced behind him and swore when he saw that the numbers of people chasing him grew once more.

"This is just fucking great! I think half of Konoha is currently after my hide." Naruto said to himself, sarcasm and self-loathing oozing from his voice. He turned into an alley and pushed down several trash bags on the way, hoping it would slow them down a bit. It was partially successful and he was able to gain some distance away from them, allowing him to escape through another narrow alley. He knew that once he gets out of the alley, he was home free.

"Trap!"

Naruto stopped dead in his tracks as he heard that voice. It was almost a whisper but he heard it nonetheless. He knew that voice. At first he thought it was just a pigment of his imagination, telling himself that total isolation from the rest of the village is affecting his sanity. But through the years, he learned to trust that voice. It had managed to save his life so many times, warning him of danger ahead. It was the voice of the raven-haired boy that always seems to be in his dreams since he could remember, of his kindred soul.

"Harry?" He asked aloud, hoping that this time, he would get a response. But he never did.

Survival instincts allowed him to sense several people just waiting to ambush him at the end of the alley. Looking around, he saw nothing in that alley which he could use to escape. In an act of desperation, he gathered his chakra to his feet and prayed he would be able to pull off this technique he was practicing but not yet able to perform. He ran towards the wall, used his chakra to stick his feet on the wall, and run up to safety. He was already half way up the four-story building when the ambushers got impatient and came in through the alley's exit only to find their prey had escaped. Soon enough, the rest of the chasers arrived at the scene.

"Where the hell did the brat go?" one of the men said.

"I knew we should have killed that demon instead of trying to trap it first!" said another one.

"Let's just look for him and finish the job! He couldn't have gotten far!" One more replied.

On the rooftop by the alley, the totally exhausted Naruto was trying to keep his breathing as silent as he can despite the fact that he needed the precious oxygen to get his strength back from running away from those people for three hours straight. Despite being a stamina freak, he was still only six years old.

Naruto frowned at the narrow-mindedness of those people. Didn't they know that he's just a vessel and not the demon fox himself? It was a real eye opener for him when he finally learned the truth when a drunken shinobi got a little talkative while trying to assassinate him a year ago. He got stabbed in the arm before the ANBU managed to capture the assassin, but at least he managed to learn the truth. When he confronted the Hokage about it, the old man was gracious enough to explain it to him and assure him that he is only a vessel for the demon fox.

It took a few weeks for the life changing information to finally set in. At first he was furious with the fox for attacking Konoha. Then his anger turns towards the Fourth for choosing him and not someone else to shoulder such a burden. Then his hate turns towards the villagers for their narrow-mindedness and trying to use him as a scapegoat for their hate for the demon fox. He even contemplated suicide once and would have gone through with it if it wasn't for Harry.

Harry. It seems his other-wordly friend managed to save his hide again. For as long as he could remember, Naruto had been occasionally seeing Harry's life through his dreams. At first he thought Harry was just pigment of his imagination, a boy whose entire life he subconsciously created to escape his loneliness. But as the years went on, he learned that Harry is his own person.

Yo, Harry. If you're seeing this, you know I owe you one, big time. He said in accented English. Naruto learned that when he sleeps, he sees through Harry's life. And when Harry sleeps, the raven-haired boy could see through Naruto's life. That is how he managed to learn a totally new language unheard of in the Shinobi World. He learned it the same time as Harry.

Naruto sighed in relief when he heard the mob moving away from the alley below. Since he was now safe at the moment, he opted to rest there first before heading home, and since it was such a nice night out, he decided to take his time. But considering how exhausted he was, combined with the fact that he used up most of his chakra to climb the wall, he felt asleep as soon as he closed his eyes.

-----Harry's World-----

Harry woke up with a jolt when something hard fell on top of his head. Looking around, he saw himself in a corner of the public library with the middle-aged librarian, Miss Holmes, standing beside him with a stern look on her face.

"Mr. Potter, this is a library, not a hotel. Sleeping should be done at home, not here." She said quietly but sternly, like every professional librarian would.

"I'm sorry, Miss Holmes, I must have dosed off while doing my research." Harry said meekly with the best puppy dog eyes he could muster.

Miss Holmes gave him a stern look but deflated later when she saw all the notes Harry had done on his small but thick notebook on the desk on the little corner of the library. She had gotten to know the boy well ever since he started spending time in the public library to do some research or another, or sometimes just to get away from his horrid relatives.

She knew he was a nice boy, and quite smart for his age considering the subjects of the books he reads. Chemistry, Biology, Japanese Culture, History, Cooking, and quite a lot of martial arts books. She also knows that young Harry is bilingual, meaning he's studying another language as much as English. And by the kanji written on his notes, he must be studying Japanese.

"Very well, Harry. Just don't make a habit of it, okay?" She said a moment later with a bit of warmth on her voice before heading back to her desk as soon as Harry gave her a nod.

Harry gave off a sigh of relief as soon as she was gone. He wasn't really planning on taking a nap but he was glad he did. First, it helped him gain back some much needed sleep after the Dursleys ordered him to clean the attic all night. Second, it allowed him to help Naruto out of a tight spot. Although, he would think twice before falling asleep in the library in the future. It wouldn't do to get banned from the only place he could get away from the Dursleys, even for a few hours.

Throughout his entire life, Harry had been mistreated by his relatives, the Dursleys. To them, he was nothing more than excess baggage, someone they have to put up with because of the sole reason of being related by blood. His aunt and uncle treats him like a slave, and his overweight cousin is no better.

Normally, such treatment would traumatize a child like him. The only reason he hasn't lashed out, or even run away, is because he knew Naruto had it worst than him and yet he still keeps himself strong, especially after Naruto learned about the Kyuubi. At least with Harry, his relatives put up with him despite their apparent dislike of him. Unlike Naruto, Harry doesn't have an entire village of ninja who wants to see him dead. Compared to Naruto's life, being hated by his relatives isn't so bad.

Ever since they learned about the Kyuubi's existence, Naruto had been secretly searching for ways to get stronger, or at least capable enough to survive. He started by studying more about chakra and how he could harness it. He then asked the Hokage if he could give him some training scrolls, which the old man happily complied with. Although most of the scrolls the Hokage gave him dwells more what chakra is and the basic hand seals used to manipulate it, it had helped him tremendously in augmenting his stamina, speed, and overall physical strength.

Harry has been doing his share by learning as much as he could about anything Naruto could use to keep himself alive. Since learning how to fight isn't possible at the moment, Harry opted to learn how to turn normal household items into possible weapons, particularly in using them to set up effective traps or distractions. Not only did he started going through Naruto's training regimen himself, he also started learning about other subjects that could help both of them to survive, like cooking for example. Despite Kyuubi's help, Naruto couldn't live on ramen his entire life.

That is how he ended up one day at the public library. He was trying to find a cook book, which could teach him how to make a more nutritious meal than ramen. Since then, he'd been using the public library not only as a great base for the research he does, but also a safe haven away from the Dursleys.

He turned back to his desk, which is quite full of books at the moment. Since he was almost finished with his research of making effective stink bombs using normal household items, he decided to stretch his legs a bit. But as soon as he got up from his chair, he fell painfully to his side. Looking at his feet, he saw what was wrong. His left put was stuck on the floor, as if someone had put industrial strength glue on it. He tried pulling it but his foot just wouldn't budge.

"Damn! Why won't it budge!" Harry said irritated as he tries to pull his foot a couple of more times without apparent success.

"You shouldn't swear so much. It's not proper, you know." Came a female voice behind him.

Turning around, he saw a bushy haired girl, about his age, sitting on a chair across from him reading a very thick book and looking at him.

The girl's tone of voice irritated him further but he managed to stop himself from making a nasty retort. Instead he said, "You would be too if someone put super glue on your shoes while you were sleeping."

"Actually, no one put anything on your shoe. I should know since I've been here reading before you arrived."

"Then how do you explain my feet getting stuck?"

Instead of answering, the girl went into her thinking pose. Harry waited impatiently, tapping his other foot. A few minutes later, she said, "I don't know."

Harry would have face faulted it his side wasn't already hurting as it is. He was just about to give her some good tongue-lashing but managed to stop himself in the last second. Instead he said, "Are you sure you didn't see anyone putting glue on my shoe while I was asleep?"

"No or else I would have seen them." She said airily. 'And sense them.' She added as an afterthought. For as long as she can remember, she had this uncanny ability to sense anyone who comes within her range of sensing, which is about 30 feet around her. Although she couldn't see them, she could sense what they were generally doing, their exact position, and, if she concentrates had enough, she could tell what their intents like boredom, excitement, anger, etc.

At that tone of voice, Harry finally had enough, he gave her a glare and said in the most sarcastic tone he could muster, "You've been a great help."

"Well, excuse me for trying to help my fellow man!" She said indignantly.

"Mendokuse." He said flatly, hoping to rile the girl up. It worked, but not the way he expected.

"I am NOT troublesome!" She huffed.

Startled, Harry asked, "You know what I said?"

"Hmp! I just so happen to know a little Japanese, you Baka!"

"Hey, I resent that! I'm not an idiot."

"Well, you started it for calling me troublesome."

Harry would have countered with an angry retort but a look from Miss Holmes across the hall silence him immediately. He took five deep breathes and mentally counted down from ten before facing the girl again and saying, "Fine, I'm sorry. Now could you please tell me if you've seen anyone or anything that could have caused my foot getting stuck on the floor."

"Like I said, no. You fell asleep and mumbled something about traps, fish swirls, and climbing trees in your sleep. Fifteen minutes later, the librarian came. That's it." She said, still angry about being called that. "Now, if you'll excuse me, I got other things to do than get insulted from trying to help. So, goodbye." She said before storming out of there.

The things she said got his mind going on overdrive so Harry didn't even paid her anymore attention. "Tree climbing? No, it couldn't be. It's impossible, isn't it? I mean," Harry said to himself in disbelief. He knew the theories behind the tree climbing exercise, he'd seen Naruto practice it many times since he stole that scroll on chakra control exercise from the ninja library a month ago.

Harry tried doing it once but he was never able to get any progress unlike Naruto since his own inner chakra is quite different from that of the blond whisker faced boy. And unlike Naruto, Harry doesn't have the Kyuubi to heal himself of broken bones overnight so he rarely gets to train himself on it.

Harry puts his hands together into the Ram Seal and started bringing forth his inner chakra, manipulating it to spread throughout his entire body. He almost gasped upon sensing the small amount of chakra continuously flowing through his foot, forcing it to stick to the floor.

He put all his concentration on putting the chakra on his foot under control. The last time he did this, he almost got into trouble after toppling over a tree in the park. Luckily for him, the chakra receded back into him, causing a sudden rush of adrenaline to leave as well that made him a bit dizzy.

"Wow! What a rush!" Harry said happily to himself as he fell down on all four panting. "Hey, where did she go?" He asked, seeing that the girl was gone.

Shrugging his shoulders, he went back thinking about the technique he obviously managed to do subconsciously.

This is a huge breakthrough. Now that he had managed to finally bring out his chakra, he could make progress with Naruto's training regimen. Although it would mean a lot of hard work, it would ensure his survival when, not if, when he decides to leave those Dursleys and start a new life somewhere else.

With the intention of starting his training as soon as possible, Harry picked up all his things from the desk after putting all the books back into the shelves. A few minutes later, he was running out of the library to look for a place to practice tree walking.

He was such in a hurry that he didn't even noticed he left one of his notebooks behind, the one that was picked up by a bushy haired girl, who decided to stick around for a while observing him from the shadows.

With the intention of giving it back, the girl picked up the notebook, never occurring to her that the contents inside would change her life forever. Not only does that particular notebook contains most of Harry's notes on charka, what it is, how to draw it out, and the proper handseals to mold it, it also contains several basic ninjutsu such as Kawamiri, Henge, and Bushin no Jutsu. It never occurred to her that by the time she and Harry meets once more five years later, she would be above Genin in skill levels.

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

In the vowels of Naruto's navel, the Kyuubi no Kitsune was frowning at the less than satisfactory level of progress of both his vessel and his charge. Although both have more skill than most people their age, it was still not enough. The Kyuubi needs both of them to be far stronger than this, particularly his vessel. He wished he could just pump more of his yokai chakra onto him but it would be too much of a risk at Naruto's current physical age. It would take several years as well as intense physical training before he could handle even a third of the Kyuubi's total chakra without turning into a vegetable afterwards.

Then, it hit him. If he could get his charge to discover and utilize the other half of his heritage, particularly that of being a wizard, sooner, then he could give both his vessel and his charge an edge against their enemies. First, he got to teach his vessel an advance form of spiritual awareness, which, in turn, his charge would be able to learn through his vessel. After that, he would leave everything to chance. It may take a year or two, but considering who Harry is to the Wizarding World, it won't take very long before Harry meets one of his kind.

The Kyuubi grinned at his own genius. Soon, his vessel and his charge would wield powers beyond anyone else on their respective worlds. By the time they begin to actively play their role in the weave of Fate, each of them would be a force to be reckon with.
