AN: My story Master Naruto will be updated sometime this weekend so look out for that one!


Naruto sighed tiredly as he continued his trek tiredly along the narrow path laid before him. All around him there was only darkness, as far as his eyes could see.

It didn't help that he was completely alone. Kurama, who's presence he could always in the back of his mind, was currently missing. He was still able to feel the chakra he had won from him so that was a small comfort at least. His missing friends weren't though.

It had happened during his fight with Tobi, Madara, he didn't know, nor did he really care at this point. The fight between them had come to a screeching halt when, out of no where, pools of darkness had begun to sprout up out of nowhere.

At first they had thought it had been Tobi's doing, but when they saw he was just as confused as them, they knew something was horribly wrong. It all became a blur after that. Small bug like creatures, the feeling of drowning, and a bright light was all that he remembered.

When he awoke he was on the pathway he was currently traveling with the oddest looking sword in his hand. The handle and guard were a solid black while the blade was a startling silver color with four sharp prongs at the tip (The Two Become One).

To be honest, it kind of reminded him of a key if he looked at it long enough. He wasn't quite sure what to do with it when he'd first discovered it, but something told him that it'd be good to keep it.

He had tried calling for his friends with no response. So, the only sensible thing he could do would be to walk and hope he got somewhere. It wasn't working out too well.

No matter how far he walked it seemed that he was going absolutely nowhere. It was disheartening to say the least. However, he wasn't one to just give up, he'd been through to much just to let a bit of walking bring him down.

He tried not to dwell too much on what had happened with everyone. He hoped in his heart of hearts that they were alright.

He looked down at the blade, at least he thought it was a blade of some kind, in his hand still wondering what it was and why he woke up with it.

He could feel the power radiating from it, very powerful, and very bright. It almost reminded him of whenever he used Kurama's chakra. Again, he wondered what he was supposed to do with it.

Looking around again he saw that nothing had changed so far, even though he felt like he'd been walking for miles.

"A little help would be nice!" he yelled out of frustration. He didn't know who he was talking too, there was no one around. That's when he noticed something out of the corner of his eye. The sword had started to glow, and as if it had a life of its own it pointed itself forward, almost pulling him to the ground, and shot out a beam of light.

Naruto stared mouth wide open as a sort of portal formed in front of him. He looked at the blade before letting out a loud whoop.

"Now that's what I'm talking about!" He exclaimed before jumping head first into the portal with a wide grin.

XxXx

"Ugh!" he grunted as he landed soundly on the hard ground. He took a good look around as he slowly picked himself off the ground. The first thing that had drawn his attention would be the large imposing tower that loomed before him.

It was a golden bronze color and surrealistically crooked. It looked like it was missing quite a few things that would normally hold up a building but it was somehow still standing. It was topped with blue cone shaped turret roofs with moon and star designs on it.

As he got a better look, past the few trees, he could now see that he was only on a little patch of land that seemed to be floating in the middle of nowhere.

He hoped there was someone in there that could help him, as he decided to make his way into the tower. Pushing open the doors he was met with the site of a simple round room.

It seemed to be surrounded by a stair case that lead to some strange green portal. He gripped the blade tightly as he walked up the stairs and into the portal.

He couldn't help but blink as he was met with even more stairs than before. Shrugging, he ran up the flight three at a time before he entered a rounded chamber filled with more moon and star patterns.

He was starting to think that whoever lived here really liked those particular shapes. As he was making his way across the room, he stopped as a small portal of darkness appeared in front of him before revealing one of the bug like creatures he had seen before he blacked out.

He looked around as more of them appeared, completely surrounding him. He bared his teeth as they lunged at him. It was little more than child's play to dodge them. They were uncoordinated with their strikes and end up hitting each other instead of him.

He stabbed the blade into the ground and put his hand into a familiar cross before shouting "Kage Bushin No Jutsu!". That's when a horrible feeling overtook him. It felt as though everything had completely stopped.

He took a shuddering breath before looking around, and finding that there were no clones next to, behind, or in front of him. He looked at his hands, and tied to form a rasengan, only for the same feeling to overtake him again.

That's when he realized it. He couldn't access his chakra. It was like it wasn't there, he couldn't feel it coursing through him, so when he had tried to use a jutsu, it felt as though it completely halted, bringing forth absolutely nothing to show for his attempts to produce it.

All of this ran through his mind in seconds, before he was tackled to the ground by the black creatures. He grunted as he tried to buck them off, but they had a surprisingly strong grip on him.

He looked around the room for something when he remembered the blade he had stabbed into the ground. He stretched his hand out only to find that it was just out of his reach.

That's when he found himself beginning to sink into the ground. He turned and looked back only to find that the creatures were literally dragging him down into a pool of darkness. He gritted his teeth. He'd be damned if he wound up back in that place.

He tried to reach the blade again, slowly getting further and further from it. He was practically willing the blade to appear in his hand when, in a flash of light, there it was, resting innocently in his hand. He boggled at it for a second before slashing backwards, taking out three of the creatures in one hit, before jumping back and gaining his bearings.

He glared at the remaining creatures before charging them, full speed. He slashed and stabbed with precision he hadn't known he had before and after a moment, they all evaporated into the air. He took a breath as he calmed down, though still alert.

It was startling and more than a little frightening to realized that he couldn't access his chakra at the moment. He tried call upon Kurama's chakra and luckily enough, he found himself wrapped a familiar blaze.

Dismissing it for the moment, he looked down at the blade in his hand. This thing had saved his life, and at the moment it seemed as though it was his only weapon. Nodding to himself he made his way out of the next doorway and came across more stairs. He felt like crying.

XxXx

After making his way up another flight of stairs, he found himself entering what looked like a study of some kind. So far, it seemed like it was the largest room in the tower.

There were several shelves containing many books, a large wooden desk with a large chair behind it, and large star and moon windows that displayed the courtyard that he was in just a while ago.

There was a door off to the side that he was somewhat curious about. But all of this became irrelevant when a voice addressed him.

"Well, you certainly know how to make an entrance young man," a deep grave voice spoke. He turned to see a rather tall elderly man standing near the windows. He wore deep blue robes and a blue cone shaped hat with yellow moons and stars on it.

He had long, gray hair, bushy eyebrows, and a long, gray beard that parted down the middle and gave off an aura of power and wisdom that oddly enough reminded him of the Sandaime Hokage. He supposed this was who lived in the tower, if the hat didn't give it away.

"Hello sir," he said slowly and not just a bit nervously. "My name is Naruto, and I was just wondering if you could help me."

"Hmm, I may... " he said slowly as though contemplating a difficult question. He moved to sit in the seat behind the desk and motioned for him to continue speaking. Naruto wasn't really sure how much he should tell him before deciding that it wouldn't really matter too much.

He didn't give too much information on Konoha and only vaguely mentioned the war. He did, however, go into detail about walking down the pathway in total darkness and everything that had happened from then on. The old man was quiet for a long time before reaching into his sleeve and taking out a small book.

"You have come to the right place if you want answers to your problems. Or rather, you were led to the right place to deal with your problems," he said. "My name is Yen Sid and I have many answers to the questions you seek. But first, it might be prudent to look through this book first."

Naruto only raised an eyebrow before picking the book up and leafing through it. There were a lot of things inside he didn't understand. Something about heartless and keyholes and the heart of all worlds.

He was going to ask what was the point of the book when he saw a picture that stopped him cold. There was a picture of a blade that looked extremely close to the one he still had in his hand. There was only one word above the picture as well. Keyblade.

"Are you done?" Yen Sid asked. He nodded before sitting the book back down on the table. "As you've most likely surmised the weapon in your hand is known as a Keyblade. It is one of the most powerful weapons in existence, and is quite picky about who wields it."

"So, it's alive?" Naruto asked confusedly.

"It less alive and more sentient than anything," he explained.

"So why do I have it?" Naruto asked. "Why did it choose me of all people?"

"It may have something to do with what happened to your world. But first, to understand that, you must understand what is was you encountered on your way here," he said while flourishing his hand. Over near the corner an image of the creature he fought earlier appeared. For a moment he was prepared to attack, until he saw that it was just an image.

"The creature you encountered is what is known as a Heartless. The Heartless are creatures of darkness, brought into existence when one loses their hearts to the darkness. They can come in many different forms, but they mostly are creatures of instinct. And one of their main instincts is to gather and collect hearts."

"When you say gather hearts," Naruto said slowly. "Do you mean they actually rip out someone's heart from their body?"

"In a sense," Yen Sid said lowly. "In every living creature exists a physical and spiritual aspect to their being. The heartless steal the spiritual aspect from people and are also the product of what happens when one loses that aspect of themselves. So no, they don't steal the physical heart.

"With the instinct to go after hearts they are drawn to the strongest that they can get to. So when the heartless appear, it means only one of two things. One, is that they're going after the heart of a world itself."

A chill went through Naruto at those words.

"The heartless will literally devour a world if they managed to get to its heart, the closer to the darkness the world itself is, the easier it will be. And if a worlds heart is devoured..."

"...then the world itself disappears," Naruto finished quietly. So that's what had happened to his home, his world. It had been devoured by these things, the heartless, and his friends had probably went with it.

"So my friends..."

He only received a solemn nod.

"But, then, how am I here? Why was I spared?" he asked.

"There could be quite a number of reasons. The first is that you must have had a uniquely strong heart. Sometimes when a world has been devoured by the darkness those with strong hearts are able to escape to other worlds, just like you did."

"So my friends could've made it out of there?" he asked desperately.

"Yes, they may have been able to make off in time," Yen Sid said as he watched the blond slump over in relief. "Now, they second reason I believe you made it off of your world is due to the Keyblade. The Keyblade is an extraordinary weapon. It is able to open any lock or vice versa. It also has the power to free hearts that have been trapped in darkness. This is why the heartless fear the Keyblade so."

"Wait, what do you mean they fear it?" Naruto blurted out.

"The Keyblade is one of the only weapons that work on the heartless. It can also stop a heartless from being able to devour a worlds heart by locking it away, which is why they fear it so."

"The Keyblade can do all of that?" Naruto asked in awe as he looked at the weapon in his hand. "What do you mean the Keyblade can lock a worlds heart away? I know you said it can lock anything but..."

"Yes, the Keyblade is, as I said, a very powerful weapon. You see, every world has a keyhole, all in different locations. If you manage to find it, you can use the Keyblade to lock it away from the heartless forever."

They were quiet for a long moment as Naruto tried to soak everything in and Yen Sid studied him. There were many questions that were running through Naruto's mind at the moment, but only three of them took precedence at the moment.

"I just have a few more questions sir," he said. "If you don't mind sir."

Yen Sid simply waved his hand.

"First, before I ask, there's something you need to know in order to answer my question." Naruto then proceeded to explain the circumstances of his birth, and his eventual friendship with Kurama. "So I was just wondering if you had any clue as to what happened to him."

"Hmm, I've not heard of something like this in quite a while," he said as he closed his eyes in contemplation. "If I had to hazard a guess, that while you have his energy, chakra I believe you said, he may be somewhere out there with yours."

It was a plausible idea, even if he wasn't quite sure about how it could've happened. But then again, with the things that had been happening lately anything was possible.

"The next thing... where am I going and how do I get there?"

Yen Sid raised a brow at his bluntness, but mostly in amusement. He didn't strike Naruto as the type to really laugh that much. He stood and made his way to the door on the other side of the room and gestured for Naruto to follow him.

"Before I send you on your way you might want to get a new set of clothes," he said while eying the clothes he had on at the moment. "They might not last the journey."

For a moment Naruto had no idea what he was talking about, that is until he looked down at his clothes.

There were rips and holes all throughout his pants and jacket and it looked like the zipper was broken. He could only rub his head sheepishly.

"Inside you'll find three good fairies. I'm sure they'll have no problem helping you with your clothes," he said. "When you come out I shall have a mode of transportation for you."

Naruto eyed him oddly for a moment before blurting out, "Why are you doing so much for me?"

He stammered at the raised brow as he felt his face heating up in embarrassment.

"What I mean to say is that why are you helping me? Not that I don't appreciate it but..."

Yen Sid eyed him for a long moment before responding.

"When I was young, like yourself, I was also a key-bearer. Now, I stand before you as a retired Master who makes it his priority to impart my knowledge and advice upon young Keyblade wielders like you."

Naruto simply stared for a moment before a grin appeared on his face.

"Thanks old man!" he exclaimed before running into the other room leaving Yen Sid staring at him in bewilderment.

"...Old man?"

XxXx

"Hello? Anyone here?" Naruto called out as he entered the little room. It was a modest cream colored room with a large cabinet and different shaped mirrors covered by sheets. In the corner were three women. One dressed in red, another in green, and the last in blue. They must be the fairies Yen Sid talked about.

"Oh hello young man," the fairy in red spoke. "How can we help you?"

"Yen Sid said you could give me a new pair of clothes?" he asked slowly.

"Oh of course," she said. "Where are my manners. My name is Flora, this is Fauna, and that's Merryweather and it'll be no problem helping you."

As she spoke, they flew over to him with tiny wings he hadn't seen at his first glance carrying them. They buzzed around him with their wands seemingly taking his measurements. It was a while before they assembled in front of him, their measuring done.

"Okay young man, are you ready?" Merryweather asked.

"You better believe it!" he yelled with a grin on his face.

"Okay girls," Flora said as they raised their wands. "One, two three!"

Lights of red, blue, and green shot out towards him and in a flash of light he was wearing a completely different set of clothes. As he looked himself over he saw that he was now wearing a sleeveless black zip up black turtle neck with an orange and blue vest on top.

He wore a dimmed set of orange pants with shuriken and kunai holsters on each leg and blue gloved with a metal plate on the back on each hand.

"Wow," Naruto exclaimed. "Thanks so much!"

"It was no problem dear," Fauna said looking pleased at their handy work.

"Good luck on your journey!" Merryweather said.

"Thanks again!" Naruto said as he left the room.

XxXx

"Are you ready?" Yen Sid said, not even turning around to face him. Instead he was looking out of the window at something.

"Ready as I'll ever be," Naruto said as he tried to see what Yen Sid was looking at. Just outside the window there looked to be a ship made entirely of blocks? Naruto sent a questioning look at Yen Sid as he tried to figure out how he was going to use this thing.

"This is what is known as a Gummi ship, a ship made out of Gummi blocks that are a special material that allows you to travel in between worlds. While traveling between the worlds you may come across other ships that contain heartless. They will try to attack you but luckily you'll be able to defend yourself with the weapons on the ship. It won't be that complicated so you have nothing to worry about," he finished when he saw the look on Naruto's face.

A moment later found Naruto sitting inside the ship with the top open, his hands on the controls.

"Yen Sid, I can't thank you enough..." Naruto started only to be stopped by Yen Sid's raised hand.

"Think nothing of it young man. It was a pleasure," Yen Sid said. "I wish you luck on you journey and I hope you have a safe one."

With a final nod to the old Keyblade Master, the lid closed and the ship took off, becoming nothing more than a dot in the distance before disappearing completely.

'That young man is a special one,' Yen Sid thought as he went back to his desk to continue his work.

As the young blond barreled through the stars he had no clue what lay in store for him, but he was more than willing to face the challenge head on.
