Kingdom Hearts: A Feather Lost

Okay, well this is my first fanfic and it is a Kingdom Hearts / Tsubasa Reservoir Chronicles crossover, but may include other worlds later on. This happens after KH2, and after the 'Acid Tokyo' arc in Tsubasa. Also to get this out of the way:

Disclaimer: All Kingdom Hearts, Disney, and Tsubasa Reservoir Chronicles characters, worlds, and such belong to their respective owners: Square-Enix, Disney, and Clamp. Also any other worlds and characters that don't belong to me belong to their owners too.

Unless of course, they're my original creations, which then they belong to me.

Kingdom Hearts: A Feather Lost

Arrival

After the fall of Organization XIII, the trio had begun to live their lives back on Destiny Islands, their home. But after a short time of that, they had received a message from King Mickey. That was about a month ago…

Sora lied down against the sandy shores of Destiny Island as he and his two friends, stared at the night sky. The trio had received a message from the King a month ago that told them that a new evil was spreading itself across the lands. But even though they were asked to help defeat it, they were told not to do anything yet and that they would know when to act when the time comes. And as frustrating as that was for them, to know that the worlds were in grave danger and just stand by and take it, they did as they were told and remained on their island. It wasn't like they had a method to leave the place anyways.

"So when do you suppose we leave?" Sora asked.

Riku sat up from his position and stared at the endless ocean in front of them. "I don't know. Soon I hope."

"Yeah, just knowing that the worlds are slowly dying is torture enough. But that we can't do anything to help is even worst." Kairi said with a sad tone in her voice.

Sora sat up, and smiled at Kairi and Riku. "Don't worry; I'm sure there's a reason why the King made us wait."

"Still, it's been an entire month since we got the message and we're still here." Riku said.

And then, the trio fell back into silence as Sora lied back down on the ground.

Staring out into the sky, they had watched the stars everyday. When they had first arrived back at home, the stars were many and bright. But lately, they have slowly decreased and grown duller than usual. They knew that the disappearance of the stars was because of the darkness that they were told of and all they could do about it was hope for the best for all their friends out there.

As the tide began to roll in, the trio knew that another day was going to pass by, which meant that another world was going to be consumed by darkness. And they couldn't do anything about it.

Standing up, Kairi let out a sigh that she knew another day was going to pass by. "I'm going to head home. Are you two coming?"

Doing the same, Riku had stood up too. "Sure, not much else we can do anyways."

Unlike his two friends, Sora sat up and shook his head. "I think I'm going to stay out a while longer. I'll talk to you two tomorrow alright?"

"Okay, see you tomorrow Sora." Kairi said.

"Yeah, see you tomorrow." Riku said resting a hand on Sora's left shoulder. "Don't stay out too late alright?"

Sora nodded, and his two best friends walked away.

Meanwhile, Sora remained sitting where he was as he stared out into the water, watching the reflection of the moon on the water. Why are you making us wait so long? The worlds out there are being lost because we're not out there to save it. As puzzled as he was about that, he was also wondering who could be spreading the darkness around.

The organization was defeated, Ansem's heartless was killed, while the rest of the villain's were also defeated by him. Well, most of them at least. Maleficent was still alive, from what he could remember, but during the battle with Xemnas The World That Never Was was destroyed. So she couldn't have possibly gotten the castle that she wanted. Whoever it was now though, he didn't really care because he was going to stop them no matter what.

With a brief look up into the stars, he mentally swore that he would save his friends. During his glance though, he noticed a rift opening up and four things falling out of it that resembled shooting stars from where he stood.

Immediately the boy stood up and in his hands both the Oathkeeper and Oblivion Keyblades materialized in his hands. Only one thing came to mind as to he saw that. Heartless.

The four things that fell out each landed in different areas, which irked him, but he raced towards the first one as it landed on the small island across the bridge.

--

On the mainland, Kairi and Riku had just gotten back from their little island, when they had too noticed the rift opening up in the sky.

"What do you suppose that is?" Kairi asked.

"I'm not sure, but they seem to be landing on the island." Riku said, remembering that Sora was still on the island. "Kairi, you go home. I'm going to go back and check it out okay?" Then, he proceeded to get back on the canoe, but felt a hand grasp his arm.

"No, please let me come too. I can use a Keyblade too, I can help fight!"

Just then, the boy had recalled handing her the Keyblade, True Heart, to her during the fight back on The World That Never Was. But just because she was able to wield one, didn't mean that she was good with one. So he simply shook her hand off and looked at her with a smile. "Just stay here okay, I'm sure it's nothing anyways, I promise."

As much as she hated the idea of being left behind again, she knew that she wasn't going to win the argument. So she nodded her head. "Just make that you and Sora are safe, okay?"

The boy nodded and began to row back towards the island alone.

Before Kairi could head home though, she had noticed that one of the shooting stars had landed on the island that she was on. With quick haste, True Heart had appeared in her hand and she rushed to the landing point.

When she had gotten there, she didn't see what she was expecting to. It wasn't Heartless, but rather, a girl. But just to be safe, she didn't let go of her Keyblade and slowly approached the girl.

"H-hello?" She asked.

In response to her, the girl didn't answer. Rather a white creature had jumped out from behind the girl and landed on top of her. "Hello, I'm Mokona Modoki, but you can call me Mokona!" The small creature said.

Grasping the Keyblade with both hands and holing it in front of her, Kairi replied. "W-what are you, Heartless?"

The white creature just stared at her with a puzzled look on its face. "Heartless? No, Mokona is Mokona!"

But before Kairi had a chance to respond, the girl under Mokona had slowly sat up. "Mokona, where are we?" She asked, as she turned her head and saw Kairi. "Oh, hi there, I'm Sakura." The girl said, not that much phased by the weird-looking sword that the other girl held in her hands.

Kairi wasn't sure who the girl was, but judging by her current state, she didn't seem to pose much of a threat. So her Keyblade had disappeared from her hands. Bending down so that they were more at eye-level, Kairi said. "I'm Kairi, um, nice to meet you. Are you okay?"

Sakura nodded as she looked around her. It wasn't long before she noticed that her friends weren't with her, which made her jump up and Mokona fall off of her. "Where are my friends?"

The red-haired girl wasn't sure what the girl had meant at first, but then remembered the other falling stars. "Oh, you mean those other things that fell. I think they would be on the island." She answered as she let out her hand. "Here, I'll get you there."

--

Meanwhile, on the other side of the island, one of the shooting stars had landed into the water. While another one had fallen onto the cove.

Upon hitting the water, Kurogane quickly swam towards the shoreline. "Damn that talking pork bun, it just has to separate all of us doesn't it? And it probably landed my in the water on purpose too." he said, angrily as he made his way towards Fai.

When he had reached land, he ran to Fai, rather then worry about being wet. "Hey, are you okay?"

Although he had lost his left eye in the previous world they were in, Fai still put on a smile. "I'm fine, you Kurogane?"

To themselves, the two could understand what they had said themselves, but not each other. "Damn, we need that pork bun to talk to each other." Looking around, Kurogane could see that they were the only ones in the area. So since speech was a problem, he simple signaled Fai to get up and the two proceeded to walk through the new world in search of the others.

--

Back on the other side of the island, the last person, Syaoran, had landed on the small island that was connected to the other via bridge. He had only managed to spend a few seconds on it before a brown, spiky-haired boy had approached him, holding two odd-looking swords.

"Who are you?" Sora demanded, keeping his distance from the stranger.

Syaoran stood up and looked at the boy. Although the boy had spoken to him, Syaoran couldn't understand a single word that he was saying. And he was sure that whatever he said, the boy wouldn't understand him either. Without Mokona speech was impossible, well, verbally at least.

But even with that knowledge, Syaoran still attempted to talk. "Don't, I didn't come here to fight." As he said that, he used his hands to signal the other boy to stop.

Unfortunately, Sora didn't understand what Syaoran was saying. But he was also unsure of what to do by what Syaoran was doing. Lowering both of his weapons, but still keeping them with him, Sora examined the boy from afar. From what he could see, there was no indication of him being a Heartless, maybe a Nobody, but he wasn't too sure.

"Just who are you?" The spiky-haired boy said once more.

"We can't understand each other without Mokona." Syaoran said, but it was useless. Looking around him, he could see that he was on a small island and his friends were nowhere to be seen. Just then, his mind quickly went to one thing. Sakura.

Rather than waste his time trying to explain to the spiky-haired boy, Syaoran immediately went off in search of Sakura, or anyone else that he knew.

"Hey wait, where are you going?" Sora asked, but got no response back. Seeing that the boy posed no threat, Sora let both Keyblades disappear as he followed the boy, wondering what he was doing.

--

"Where the hell is everyone?" Kurogane said, quite displeased that they were all separated. Behind him, Fai followed.

It wasn't long though, until they had run into someone else. A silver-haired boy stood in their way.

"Who are you?" Riku asked, but neither of the two understood.

Rather then waste his time, Kurogane just continued walking forward. It was after all, pointless to talk to someone that you don't understand.

But before they could go any further, Riku had called upon his Keyblade, Way to the Dawn. "Stop right there and tell me who you are."

Kurogane stopped at the sight of the Keyblade. "So you want to fight then kid?" Though he lacked his own weapon at the moment, he was still ready to fight, regardless of that fact. Nor did he care that he posed no threat to the boy to begin with. "Well if you want to then show me what you got."

Riku wasn't sure who the two were, but the one dressed in black clothing appeared to be provoking him into a fight as he had his hands out into fists. The boy wasn't sure what the man was thinking, but if he thought he could beat him without a weapon, then it wasn't his fault if he won. So without another word, Riku rushed in and swung his Keyblade at the man's side.

"You're going to have to do better than that kid." Kurogane merely said as he sidestepped to the left to dodge it. Then before Riku had another chance to attack, Kurogane threw a kick at the boy's side, but only managed to hit a dark barrier that surrounded the boy. A smirk appeared on Kurogane's face as he saw that. "Looks like you got a few tricks of your own. This is going to be fun."
