Notes: Well, this fic is loosely based on Kingdom Hearts. (The first one.) This will be mainly a crossover between seasons (all five) though there might be some other fandoms coming into play later on.

Prologue: The Plans They Made

Her hands hovered over the piano keys quite nervously. Her eyes did a quick search around the small white room. Other than noticing it was slightly cloudy outside through the small window in the wall, there was nothing worth noting. It was just her and the large piano, which by itself took up most of the space, in the room. She adjusted her position on the piano stool and put her fingers in the positions that her mother had taught her so long ago.

When she started to play, her fingers messed up the movements needed to play the music on the sheet of music in front of her. Wincing, she tried again. Again, her playing did not produce the right music. It was a simple piece and she had done it many times before, sometimes in front of small audiences. She tried to start from the beginning. Again, the music was not produced. The movements of her hands on the keys were slow and clumsy, not the movements needed to play the piano correctly.

A bolt of pain, originating in her chest, shot through her body. This in itself wasn't unusual, she should have expected it. Gripping her chest where her heart had been before they had gotten a hold of her, she felt the familiar lump there. "This is the worst," she muttered to herself. The phrase had long lost its power for her, but she still sometimes said it to remind herself who she was.

"This is the worst," a voice said mockingly from the doorway behind her. "You're a funny one, Mozart. What are you trying to do? Bring down the ceiling with your 'beautiful' music?"

She didn't have to turn around to know who the owner of the voice was. "I wouldn't be talking like that," she said quietly. "What did I see last night, again? Oh yes, you were trying to fly. You fly well enough but you need to watch out for walls, trees, and Ruki. She doesn't like being your landing pad."

The figure from the doorway gave a thin growl. "I didn't come here to be insulted, Yoshino," the voice said in a more reasonable tone.

Yoshino turned around to face the figure, still gripping her chest. She looked the blonde over, from head to foot. She was younger, with piercing sea green eyes and a confident smile was almost always on her lips. This time, there was no smile but a tight lipped expression that showed her irritation. Like Yoshino, there was faint traces of blood on the shirt she was wearing. "I see. Well neither did I, Izumi," Yoshino replied. "I came to practice in peace and you came barging in here like you own the place."

"I did not!" Izumi snapped. Although her face was still a pale white, Yoshino could tell that her face would have been flushed if it could.

"I mean," Izumi said in a more reasonable tone, trying to calm down. "I didn't. I just wanted to tell you that they caught another."

Yoshino gave a low sigh. "Is that all?" she asked quietly. "Which world is she from?"

"Mine."

Yoshino raised a thin eyebrow. "Yours?" Yoshino asked feeling surprised. "So I take it that you know her."

"I do, though hardly," Izumi said, her voice uncharacteristically calm. "And things were just starting to look up for her..."

"I see. So... What's her name?"

"Chiaki."

Yoshino gave another sigh and turned back to the piano. "This makes four of us 'living dead'. Why do I have a feeling Ruki is going to be ecstatic about this newcomer?"

"Because I am. If they keep on choosing people from powerful worlds, I think we'll be able to fight back."

He sat lazily in front of the others, his eyes flickering from minion to minion. Of course they never thought of themselves as minions but allies. He gave a small smile to himself, showing his vampire teeth.

"Another one was found," he announced, standing to his full height.

In the dim light of the room, a pair of red eyes flashed with anger. A pair of teeth, just as sharp as his, was bared with anger. "Oh yes," a female voice said sarcastically. "Another was found. Someone who is, oh I don't know, basically related to me! That Izumi is finally getting what she deserves but what did the other do?!"

A shimmer of metal betrayed the movements of another. "By all rights we shouldn't be here," a masculine voice said, part sympathetic and part amused. "Quit your whining."

His grin widened. "He's right, you know and I thought you hated human females," he taunted the first speaker.

"Fine," the female voice retorted, slightly embarrassed. "Be that way. I didn't say anything. Quit laughing, Spider Face."

Another female voice had started laughing in a haughty way that seemed to annoy the other. "Oh? Stop laughing?" she asked in a condescending tone. "Do you want me to get down on my knees and worship you like those brain-dead morons in your world, too?"

"Shut up," the first female voice muttered. "I'm not in the mood to evolve and stomp you flat."

"I wasn't beaten by a little blonde girl," the second continued. "You were, though. Why? Oh, yes. You were the faulty link in your plan..."

Another female voice chipped in. "What's wrong with being blonde?" she asked. "If it has something to do with being dumb, I assure you I'm not one of the dumb blondes. I can outwit a genius."

"And killed by one," the male voice said flatly. "So much for strategy."

"Honey never made strategies," another male voice said dreamily. "She is my type. I feel that we shouldn't have taken her heart. I will never say this out loud, of course, for this is treason."

The owner of the third female voice smacked the second male voice with what sounded like a stick of some kind. "We can hear you, Ivan," she said flatly. "Can't you keep anything inside that thick head of yours?"

"You must be psychic, I didn't say that out loud," Ivan said.

"Enough," the leader said loudly. "You, please keep your mouth shut in the future. This means you, too, Ivan. To change the subject, we have located another possible candidate. This time from my own world."

"Which one?" the second female voice asked eagerly.

"The one of Light, Hikari."

There was murmured excitement around the room.
