Thanks for deciding to read my fanfic! So this story is about when a girl with a past she's reluctant to reveal begins to travel with Sora. Well, yea, Buncha AU, and it takes place after Kingdom Hearts was sealed. Also, I know there are a few stupid chapter titles, but yea, I'm not good at chapter titles! Anyways…

I wrote this like, a year ago… I'm doing my best to edit it, but sometimes that can get really hard… So yea, this was finished before KH2 was released...

Disclaimer: I don't own KH or KH2 or any characters, except for Reiko.

Chapter One: Twilight Key

"This key is the secret?" A girl with dark blonde hair stared at an overgrown key in her hand. Her knee length gray skirt and gray trimmed white shirt with a gray tie (lotsa gray!) fluttered in the breeze.

She turned her attention to a figure standing in front of her. He had two large ears and wore a black cloak. "Yes, that's what has unlocked your powers. You are the one who is to permanently connect the scattered worlds."

The girl went back to staring at the key blade she held. Its three-foot long blade was pure white, the handle pure black, and the key chain was of a gray heart. The girl was somewhat short herself, barely standing over five feet. At times, she tended to act like a bit of an airhead, causing some ugly rumors about her to spread, but she was still pretty smart compared to the average fifteen year old.

"Your highness, are you sure I'm right for the job?" the girl put the blade away.

"You were chosen by the Twilight Key. It's your job now Reiko." Mickey paused for a moment. "You will be working with the one that locks the hearts of the worlds."

Reiko nodded and smiled brightly. "So, when will I get to meet him?"

"Wow, It's amazing!" Sora stared out of the window of the gummi ship amazed.

"Ahh, so wonderful to be back! It's been so long." Donald said as he steered the ship.

"H-yuck. I wonder why the king called us here anyways. Any ideas?" asked Goofy.

"King Mickey just said it was urgent. Something about connecting and some Twilight Key, whatever that is." Replied Donald as he safely (but not steadily) landed the ship.

"Well, I suppose we better find out!" Sora grinned as he got up and jumped onto the platform.

"Queen Minnie! It's a pleasure to see you again!" Donald said after stepping onto the platform. The three bowed.

"Mickey is waiting, please, come this way." Minnie replied with a smile.

Within no time they were standing before a pair of elaborately decorated doors. Minnie let the three in and left to the library.

Sora looked ahead and saw the king and a strange girl. The first thing he noticed was a pair of beautiful sea-green eyes. The girl looked up and smiled as they entered.

"Donald, Goofy, It's been a while." She turned and bowed.

"Li'l Rei? What are you doing here?" Donald replied surprised.

Reiko giggled. "I'm a teen now and yet everyone refuses to drop my old nickname."

"Her power has awakened, so I request that you two take her with you on your journeys." Mickey turned towards Donald and Goofy.

Sora then cleared his throat, beginning to feel left out of the conversation.

"Ah, yes. Reiko, this is the key blade master, Sora." King Mickey introduced the two.

Reiko curtsied and smiled, " It is a pleasure to meet you Sora."

"Same here." Replied Sora as he gave a small bow in reply to her curtsy.

"Oh, please just call me Rei." She smiled.

Mickey looked at Sora. "Reiko is another Keyblade wielder, though she holds a different purpose. She is able to reconnect the worlds similiar as to how they once were but not as one like they were ages ago.

Reiko smiled and pulled out her key blade. "I'm still not that good at fighting with this. Think you'll be able to help me if I get stuck?"

"Yea, I guess so." Sora smiled back.

"Now, all of you better get some rest." Mickey intervened, "Tomorrow you need to begin to backtrack to the worlds that have already had their keyholes sealed in order to connect them."

Reiko nodded and led the trio to their respective rooms. She paused before leaving Sora's room.

"I hope to get to know you well." Reiko smiled, "Good night and sweet dreams." She closed the door and walked to her own room.

"Wow, talk about kind. Doubt she's been without a smile this whole time." Sora yawned as he lay down and fell into a rare, peaceful sleep.

Reiko held her key blade and examined it. "It's so beautiful!" she smiled as she laid down and stared at the ceiling. "I'm going to get to travel to new worlds!" She began to giggle and soon fell asleep, hugging the Twilight Key.

The sun rose quietly and Reiko suddenly woke and looked around. She let out a big yawn as she peered at the clock.

"It's morning, Yes!" She jumped out of bed, causing her key blade to fall to the ground. "Oopsie daisy!" she picked it up and put it away. Her gaze traveled around until she finally decided to take a walk through the garden.

"Days fly by,

Lights fall from the sky.

I watch as your heart sprouts wings,

It flies away along with the love it brings."

Sora sat up as he heard someone singing. He looked around and then saw Reiko walking along the path ahead of him.

"My eyes grow weary,

But sleep eludes me.

Your love is now so bleary,

It has flown too faraway from me."

"Rei?" Sora stood up as he brushed himself off.

"Sora, what are you doing up so early?" Reiko stopped in front of him.

"Don't know. I woke up and couldn't get back to sleep." He smiled, placing his hands behind his head. "So, What was that song you were singing?"

"Oh, just a song my mom sang to me when I was little." She smiled and sat down.

Sora nodded and sat next to her. "How long have you known Donald and Goofy?"

"Long time, perhaps about seven years."

"Wow, how'd you end up here?"

"I was sent here by my parents so I could train. Heh, I'm here seven years and my skills haven't improved much."

"Why did your parents need you to train here?"

"Heh, you sure ask a buncha questions." Reiko replied as she giggled. Well, my castle's prophecy dude read a prophecy that said 'The youngest child of the great King and Queen of the Rayzo era is destined to bring the worlds together,' or something close to that."

"Weird…wait a second! That means you're a princess!" Sora's eyes widened in shock.

"Yes siree!" she began to giggle. "So, what is your world like?"

Sora blinked and replied, slightly embarrassed from his outcry. " Well, it's an island. Not even that big of one, but it was still nice." His voice trailed off as he smiled at the sky, laughing to himself about all the 'adventures' he and his friends had had.

Reiko smiled too. He had seemed troubled earlier, good thing I came and fixed that! She looked at the sky and quietly giggled about various things and time passed by.

"There you two are!" Donald exclaimed from the doorway while tapping his foot. "I've been searching everywhere for you!"

The two stood up startled and Sora spoke. "Sorry, we had just started talking."

"That doesn't matter now, we have to leave if we want to get this done before it gets to late night!"

"Jeese, Donald. Can't you even try to be nice? I guess I just have to learn to live with it." Reiko smiled brightly as she giggled from excitement.

Both Sora and Donald stared at her speechless.

Donald shook his head, " Is it just me, or does that girl laugh a lot?"

"That's probably the fourth time she's laughed in the past five minutes." Sora then began to follow Reiko to the ship with Donald.

"Well that girl better not cause us any more trouble!" Donald replied, glaring at Sora.

Sora laughed it off and avoided Donald's glare.
