Kingdom Hearts

Midnight Princess

A girl in a long black, hooded cloak which covered her face ran through the Midnight Castle's courtyard cutting through the creatures in it's way with a dark blade. It was dark and hard to see what, and who, was around the figure.

"Stop." A man's voice called.

The girl turned and saw the man who the voice belonged to. The figure held it's battle stance as the man walked closer. He was in a military uniform and had a scar going down his face staring on his right cheek and ending at his chin.

"Put it down. You shouldn't be playing with that kind of weapon, it's dangerous."

"You should know. I'm not just some helpless little girl commander. I think I can fend for myself." The girl smirked as she cast a spell disposing of the rest of the creatures and turned and ran from the commander, then disposed of the blade, waved and did a back flip over the wall which led to a 50 foot drop to the sea. The girl opened a portal and went fell through it and disappeared.

"Code red! The princess has escaped!" The commander yelled for his guards.

Sora, Kairi and Riku were all laying on the beach when the sky suddenly went from perfect and cloudless to stormy.

"Oh joy. A perfect day ruined by a storm," Sora complained, "this is just our luck!"

Riku laughed and Kairi giggled. Riku's face then turned serious. "Something's not right."

"Not again! We've only been home a month!" Sora groaned. He then got the same feeling as Riku and stood. "Kairi, go home."

Kairi stood and glared at him. "No way! I'm not gonna let you two have all the adventures!"

Riku and Sora both looked at her then decided not to argue when they saw the glare they were receiving.

Suddenly a dark portal opened in the air above them and a person in a black cloak fell from it. Riku opened his arms and caught the person as the hood fell off, revealing it to be a girl with black hair that was purple underneath. Her hair went to the middle of her neck and she had side swept bangs. She was unconscious from lack of energy.

"Whoa." Sora and Kairi both said at the same time looking at each other with wide eyes. Riku stared at the girl in wonder and confusion.

"We can take her to my place, my parents won't be home for a couple of days." Kairi suggested.

Riku nodded and together the trio walked to Kairi's. Once they got there Riku laid the girl on the couch. The cloak fell open to reveal a long purple dress with black lace over it. "Whoa." Sora and Kairi said again.

"Her heart seems to be full of light...but it's blocked by darkness..." Riku muttered.

Kairi looked at her for awhile. "Do you think she's a princess or something?"

"She looks like one.." Sora mumbled. He was studying her when there was a crash outside."I'll be right back." He summoned the Kingdom Key and walked outside, where he was surrounded by creatures that were nothing like the nobodies or heartless. They were purple with green markings along their chest forming a broken diamond. They had deep black soulless eyes and looked ready to fight.

Sora started to raise the keyblade when they suddenly vanished. Sora looked around confused before disposing of the keyblade and walking back inside.

"What happened?" Kairi and Riku asked.

"There were these creatures outside that I've never seen before...they vanished before I could even hit one. I raised the keyblade and they disappeared."

The girl suddenly shot up and her eyes shot open, they were purple. "What did they look like?" She questioned looking worried.

"They were purple with green markings that formed a broken diamond."

The girl muttered envies under her breath as she started to stand but fell forward into Riku who in turn helped her stand. "Thank you." She muttered sounding somewhat embarrassed. "I'm sorry for bringing those creatures here."

"You brought them?" Riku questioned.

"In a way. Commander William sent them after me when I escaped the castle," she then noticed them giving her a questioning look. "My name is Naomi Lynn Knight."

"Are you a..princess?" Kairi asked quietly.

"I don't see that it's any of your business." She seemed distressed by that question.

"What castle were you at?" Sora asked.

"Midnight Castle."

"Never heard of it." He put his hands behind his head.

"I have." Riku muttered. Naomi looked at him confusedly. "It's where the Midnight Princess lives." He looked at Naomi as he said that. "Where the king of darkness lives-"

Naomi cut him off, "Lived. He's dead."

"Oh. Well lived then, and where most of the evil beings are created." He was still watching Naomi.

Naomi glared at him then dragged him to another room. He smirked at her.

"The princess sure is feisty."

"How do you know I'm the princess?"

"I'm smart. Plus if you weren't the princess why would you be wearing that dress?"

"Maybe I'm wealthy?"

"Why would the Commander care if you left?"

"Maybe I'm his daughter?"

Riku just looked at her. She sighed and stormed away from him.

"Princess Naomi has a temper!" He yelled loud enough Sora and Kairi heard.

"You seem really familiar you little ass hole."

Riku just smirked as a response. Sora and Kairi looked at him then at her.

"I don't have time for your questions, I have a world to save...well technically allot of them, but you get my point."

"Let us help." Sora said.

"Yeah!" Kairi agreed with a smile.

Naomi sighed. She'd always hated people offering their help. She wanted to be independent. Like before. "Fine...but I'm going to require a place to sleep tonight. Please."

"We can all stay here." Kairi offered.

"Alright. You will all be ready by dawn." Naomi smirked as Sora groaned. "You don't have to go you know."

"No, no it's fine..I'm gonna go pack now though. Riku come on."

Riku rolled his eyes and him and Sora walked out and then made a bet on who could run to Sora's house faster and took off running.

Naomi shook her head watching them, never taking her eyes off Riku as he ran. What is it about him? Why is he so familiar?

Kairi broke her out of her thoughts. "So, you're the Midnight Princess?"

Naomi sighed. "Yes. No more questions please."

"Do you-"

Naomi sighed again. "I said no more questions."

"-want some clothes?" Kairi finished.

Naomi shook her head. "I can get my own clothes." She cast a spell and was suddenly in a pair of black short shorts, a purple tank top, a pair of purple converse and a green fingerless glove on her right hand that had a purple broken heart with wings on it. "I'll have to give you all new clothes as well." She cast a spell and Kairi's clothes changed.

She was now in a light pink long sleeved shirt, white short shorts, and pink sandals. "Nice." Kairi smiled.

Naomi shrugged and sat down on the couch. This was going to be a long journey. She sighed.

Sora and Riku got back after a couple of hours and Naomi gave them both new clothes.

Riku was now wearing dark blue jeans, a silver long sleeve shirt with a black with yellow vest over it and black converse. Sora was wearing blue jeans, a black short sleeve shirt with a blue and yellow vest over it, he was wearing boots as usual and his crown necklace.

Naomi had fallen asleep on the couch due to lack of energy. Riku decided to sleep in the living room to keep an eye on her, he didn't seem to trust her much. Sora and Kairi were asleep upstairs; Kairi in her room Sora in the guestroom.

Naomi was currently having the same nightmare she'd had for years.

Naomi seemed to be watching a memory, but she couldn't actually ever remember this happening.

"Naomi! Stop!" A female voice called after a young Naomi as she ran towards an alley. Young Naomi stopped and turned towards the voice happily but didn't see the woman who had yelled for her so she frowned and continued to run. She wasn't hurting anybody just being a normal six year old and exploring.

When she ran down the alley she discovered it was a dead end. She heard footsteps behind her and hid. A man with a long scar down his right cheek was walking down the alley. Naomi recognized him as commander William but her younger self didn't know who he was. "Oh little Naomi where are you? I'm not going to hurt you or anything." He had a smirk on his face.

"Stay away from her!" The female voice returned. Naomi tried to remember that voice..it was so familiar...yet not at all.

Young Naomi watched scared as the woman approached the man. The woman locked eyes with the woman and knew that she was supposed to run now but she just couldn't do it she couldn't run, she couldn't even move she was so scared.

"I'll go where I choose to go, peasant."

The woman glared at him and stepped forward. William pulled his gun out of his holster. "I'll shoot if you don't step away." The woman stood her ground.

"I'm not afraid of you. If you shoot me, I'll die, so be it, but Naomi will remain safe."

William aimed the gun and pulled the trigger. Young Naomi closed her eyes and covered her ears and tried not to scream.

Naomi woke up scared and slightly sad, but she didn't know why she was sad. She didn't know who this woman was, she couldn't even remember a time of being outside of the castle. She put her head in her hands as she tried to shake the dream off.

Riku woke up around that time and noticed her. "Hey are you okay?" He moved over to her and put his hand on her shoulder.

"I'm...fine. Bad dream that's all." She looked up at him. He was kinda cute. She shook her head. No falling for anyone. Especially not one of them.

"Oh," he sat next to her, "you want to talk about it?"

"Not really..." She lied. She really wanted to, she just knew she couldn't. Too risky. "Get some sleep."

"I'm fine."

"Are you really going to stay up with me, just because I had a nightmare?"

"Yeah, I figure we need to become friends if we're going to be stuck with each other for awhile."

"Alright fine." Naomi sighed. But she was secretely happy. She'd longed for someone to talk to for a long time now.

"So tell me about yourself."

"Well, I'm 15, miserably lonely, a princess, love purple and all things light, and happy. Oh, and cats. What about you?"

"I'm 17, have friends but I'm kinda lonely myself and that's all I have to say really."

"You seem boring now." She giggled as she said it.

He laughed. "Not really I just don't have much to tell about myself. Do you have anything you want to say about your past or something?"

"I can't remember anything before I was seven...and everything else I don't want to talk about."

"So your dad was the king of darkness?"

"Yes."

He suddenly noticed the green marking on her right thigh barely noticable under her shorts. He pointed at it. "What's that?"

She looked down then pulled her shorts up enough to reveal a green broken heart with wings. "The symbol of my mother's family."

"They had a symbol?"

She nodded. "It's complicated why. I have another symbol on my left arm." She showed him the broken diamond. "That's the symbol of Midnight."

He nodded, understanding.

A few hours later they were both asleep. She was leaning against him with her head on his chest and he had one arm around her. They didn't mean to end up in that posistion but sometimes you just can't help what happens.

When they woke up Kairi and Sora were still asleep. Riku was the first to wake up. He looked at Naomi. How can I tell her that she's met me before? How could I explain it without her hating me in the end? He thought sadly.

Naomi woke up a few minutes later. When she realized her posistion she shot back away from him. She was blushing. She jumped up off the couch. "It's dawn, why aren't they up yet?" She marched upstairs and woke Sora and Kairi up.

An hour later they were all outside.

"How exactly are we getting off the islands?" Sora asked with his hands behind his heads.

"Magic." Naomi replied. "Say bye to your islands, it's gonna be awhile before you're back here."

Riku, Kairi and Sora all looked at the islaands and the sea. They said their goodbyes and Kairi hugged Sora and Riku. Which in turn made Sora blush.

Naomi noticed him blushing and frowned. Love only gets in the way you fools. You'll get us all killed. She tought angrily.

After they finished saying their goodbyes Naomi opened a portal which they all stepped through, marking the beginning of a new journey. This time, the trio would stick together and stay with Naomi.

Secrets will lead to your demise. A voice in their heads said. Kairi and Sora disregarded it thinking it was nothing. Riku and Naomi both had secrets and knew that it was serious.
