Her Devoted Heart

"W-where am I?" The young woman asked in a dark abyss. She was slowly falling down the endless darkness and there was nothing that can save her. "Am I falling into the darkness? Is there nothing for me in this world? Just darkness…"

Chapter 1: Xiaka

A young woman opened her eyes and her blurry vision started to become clearer. She gasped and placed her hand on her chest; for some odd reason, she thought she felt like she had been struck in the chest. But there was nothing. She looked down at her clothing; she was wearing a black turtle neck crop top, black leather shorts and knee high socks and black ankle heeled boots. She saw a broken mirror on the floor and looked at her reflection. The mysterious teenager had shoulder length brown hair with bangs framing her face, slightly tanned skin, blue eyes, freckles and full lips with dark red lipstick.

She heard foot steps and looked up to see someone standing above her. This person wore a black long coat with a silver zip, the zip ended at their navel and opened up to show they were wearing black short, knee socks and black ankle boots with heels. From their body, the girl assumed this mysterious person was a woman. She took off her hood and pulled out her hair from the back of her coat.

The woman had silver long hair up to her hips, tanned skin, bright yellow eyes and her ears were pointed. The mysterious woman was 5ft 10in with the younger woman being 5ft 5in. She piercings on her face; a labret piercing as well as a nose piercing, with 4 helix piercings on one ear, 2 on the other and upper lobe piercings on both ears. She wore black matter lipstick, mascara and black nail polish. She had a very cold glare in her eyes as she looked down at the girl; who was very intimidated.

"Who are you?" She asked in a husky voice. The young woman just stared up at her clueless and not mumbling a word. "Do you seek answers?" She nodded and the older woman raised her hands. Letters appeared between the 2 spelling out a name:

Aika

"Nothing for you is real and I can give you purpose." The letters then spun around her. An 'X' appeared and was put into the name, creating a new one.

Xiaka

"This is the new you." She said and turned around. "You will wait here; someone will return and take you from here." The woman then walked off and opened a dark portal. She entered the portal and then disappeared.

Xiaka stood up and looked around her. She decided to walk up the stairs and explore this old mansion. She turned right and entered a room. As she closed the door behind her; she heard a man's voice.

"Leave at once!" The man shouted.

The room's floor was open and revealed some stairs leading to some sort of basement. The dark haired woman looked down and saw a man. He had red bandages on his face and save from his right eye and mouth and wore a lot of red, black and brown. There were the ink black monsters with yellow eyes, claws and antennae cornering him. They were about to jump towards him and Xiaka's body just moved by itself.

She jumped down and landed in front of the man with her left hand out. Out of nowhere, a weapon appeared in her hand. It was a Keyblade; the shaft was golden, there was a crystal symbol of gust of wind at the teeth of the Keyblade, dark blue handle and a keychain with a yellow star shaped lucky charm attached to it; she named this Keyblade Astraeus of the Dusk. She then used the weapon like a sword and swung it against the enemies. The enemies then disappeared when she had defeated them and their hearts floated in the air and disappeared.

"Who are you?" The man asked and she turned around.

"My name is Xiaka." She answered.

"You saved me, thank you, child." He smiled and she shook her head.

"What is this place?" She asked.

"We are in Twilight Town. This is an Old Mansion." He stated. "Where did you come from?" Her eyebrows furrowed together.

"I…I don't know." She answered whilst placing her hand on her chest. "I don't know where I belong."

"Come with me. There may be more Heartless around." He said and she followed him. They walked downstairs into a computer room which looked pretty empty and new. "Don't you have any memories?"

Xiaka looked down sadly; of course she did. But those memories were of her own, they were someone else's.

"They're not my memories." She mumbled and the man looked at her with wide eyes. "I guess I just appeared here."

"You're a Nobody." The mysterious man said and she looked up at him with an odd look.

"Excuse me?" She asked.

"When someone loses their heart, a Heartless is born; they are the beings you saved me from. When a Heartless is born, the body and soul left behind are reborn into this world as a different being. That is a Nobody." He explained.

"So I have no heart." She mumbled.

"You're not with the Organisation, are you?" The man asked suspicious.

"Organisation?" She asked and he sighed with relief.

"You may have just been born as a Nobody." He answered.

The man felt like he had his life indebted to Xiaka, so he chose to trust her and appoint her a task. He told her his story and how he desired revenge; something Xiaka understood because of everything that had happened to him. DiZ then told her of his plan; how he would bring Organisation XIII down and find out what they want to achieve. She told him that when she had first awoken, a woman in a black coat gave her a name and a purpose. He then came to a realisation that this was Xahna, the sub leader of Organisation XIII.

"How would you feel if you work with me?" DiZ asked. "It may be dangerous, but it is entirely up to you."

"It would be the right thing to do. But I have one condition." She stated. "I want freedom to do what I believe is right. The first being apart of this Organisation XIII. It would be suspicious if Xahna does not find me when she returns."

"That is true and of course. You are free to do as you please." He stated. "It is best if you get going then."

"I'll see you when I see you." Xiaka nodded and then she left.

The young Nobody exited the room and walked back upstairs. The basement closed up and now there was just an ordinary floor. She exited the room and walked down the stairs. The young Nobody sat on the steps and decided to wait for Xahna.

Instead a hooded person came out of one of those dark portals and the girl could tell it was Xahna. The person had a black coat too and was carrying one in his arm; he was 6ft.

"Xiaka?" A deep yet sexy voice called out and he turned around to see the girl. When his eyes fell on Xiaka, he felt his cheek burn up and his heart skip a beat; she looked like…her. He then shook his head and walked towards her. "Hey cutie." He sang and looked up and down. "Damn, I shouldn't even give you this coat. You're so hot the world needs to see that smoking body."

Xiaka got up and sucker punched the mysterious man who shrieked loudly and wrapped his arms around his chest. She took the coat from him and put it on with the zip ending at her navel.

"Why did you do that?!" He asked.

"Cuz you're a pervert!" She countered back.

When he looked up at her, his hood went down and she saw his face. Her eyes widened and she gulped; he looked like…him. The Nobody had brown wavy hair tied in a manbun, a beard and moustache, the same yellow eyes as Xahna, tanned skin, 2 helix piercings on one ear and standard piercings on both.

"Who are you anyway?" She asked whilst crossing her arms.

"I'm Xuko, Xahna's younger brother." He answered. "Please don't punch me again."

"No, I'll punch you when you deserve to get punched." Xiako glared at him.

"We better hurry and get back. Follow me." Xuko laughed nervously and led her into the portal.

When she got out of the portal, she appeared in this white living room. She saw Xahna standing in front of her staring into her soul.

"Welcome to Organisation 13, Xiaka. I must inform you that you, including both Xuko and I are not officially in the Organisation yet." She stated. "You see there are 5 suspicious Organisation member who will be sent to Castle Oblivion to be disposed of. After this, we will be apart of the Organisation."

"Yeah so don't blurt out anything Xahna said to anyone but Xemnas okay?" Xuko added.

"Who's Xemnas?" She asked.

"Xemnas is our leader." Xuko answered and turned to his sister. "Don't tell me we have to tell her about every single member?"

"No, they will come and meet her." Xahna said.

A door opened and 13 people came into the room. They all lined up and there were murmuring.

"Wow, I kinda feel special with all these Nobodies wanting to meet me." She giggled.

A tall man towered over her; he had long silver hair, tanned skin and amber eyes. Her eyebrows furrowed together; he reminded her of Terra but with silver hair, darker skin and different eye colour.

"Welcome to Organistion XIII, Xiaka. I am Xemnas." He stated and the girl placed her hand on her chest as her head lowered with respect.

"It's an honour to meet you, Superior." She stated and Xemnas walked away with Xahna at his side.

A man stood in front of her; he had golden eyes, pointed ears, upturned eyebrows and dark hair with a few grey streaks tied back in a ponytail. His right eye was covered with a blindfold and he had a jagged scar under his left eye going down his cheek. His smile quickly disappeared when he saw Xiaka. His eye widened but he leaned closer to her. Her eyebrows furrowed together and she crossed her arms.

"Um, what?" She asked.

"You look familiar." He squinted.

"Yeah and you look like you got beat up pretty bad." She said and everyone went quiet at this. "The guy was probably pissed cuz you didn't know what personal space is!" She growled whilst glaring at him. "And if you don't respect MY personal space I'll deal a number on you and you'll have to wear another eyepatch." She growled quietly and he pulled away with his hands up in surrender.

"Damn, she's feisty." Xuko smirked.

"Aw come on. Take a chill pill. Anyway I'm Xigbar." He stated and turned around; that girl she looked like Terra and it was odd.

The next person to meet her, made her smile; it was Dilan. But then her smile dropped when he stared at her. He was so different, so emotionless and she hated it. She remembered when Dilan used to pick flowers with her and would carry her on his shoulders. But this person he was not Dilan.

"I am Xaldin, Number III." He stated. "I hope that you prove useful to the Organisation." She nodded whilst looking down.

When she looked up to see who was to meet her next, the smile returned to her face. It was Even and she couldn't deny it. In the past, he'd read books to her and it was thanks to him, she became a smarter than she was before. Hopefully, he didn't disappoint her. The man smiled back at her.

"It seems you have grown up, little one." He said whilst rustling her hair. She couldn't help but giggle at this; Xuko was a bit suspicious of this. "You've become a Nobody too. I wonder why. Well anyway, you shall address me as Vexen."

"Mr Vexen." She corrected and he nodded.

The next man who met her kept the smile on her face; it was Aeleus. She remembered when he used to invite him and Dilan over for tea parties. He looked at her and smiled sweetly at her.

"Hello there, little one." He stated. "It's Lexaeus."

"Would you like to join me for tea?" She asked with a giggle and he nodded.

"After 10 years? Of course." He said and Xuko's suspicions were right.

Her smile became wider when she saw the next boy; it was Ienzo. She felt something inside her became warm when she saw him. She would always have sea salt ice cream with him. He looked at her and his eyes widened as his cheeks turned pink.

"Y-you're here?" He asked and she nodded. "I'm glad you're okay."

"It's nice to see you again. Let's got get some ice cream some time and catch up, okay?" She asked.

"It's Zexion now, and of course." He nodded walked off.

"I never imagined I'd see the people from my past. I wonder who I'll meet next." She said to herself.

A man with blue hair stood in front of her and when she looked up at him, the smile was still there; it was Isa but…he had yellow eyes and his ears were pointed. But it was still him. She then noticed his scar and raised her hand to touch.

"Isa, how did you-" He grabbed her wrist and squeezed it tightly. Her eyes widened and she gasped.

"My name is Saix, you will not call me by that name. Understand?" He asked and she looked down slowly with a nod; she was crushed. He was another one of her friends; he's always play with her alongside his other friend…

"Ignore him." She heard a voice and she looked up.

When she saw this boy, her cheeks went pink and her eyes widened. When he saw her too, he gasped. They both couldn't believe it. Instantly, she wrapped her arms around him and hugged him.

"Lea, it's you…" She mumbled.

"Didn't think you'd miss me that much little one." He smirked and she looked up at him with a pout.

"I'm not little anymore." She whined and pulled away from him. "I hit puberty, damn it." He couldn't help but laugh at this whilst shaking his head.

"Yeah you've really grown up. You became really pretty, y'know that?" Her eyes widened at this and she looked down with pink cheeks. Xuko just rolled his eyes. "Well, the name's Axel now, got it memorised?"

Xiaka met the other members of the Organisation; Demyx who she liked and found funny, Luxord was okay, she didn't really like Marluxia and she hated Larxene because she called her a brat.

When the young Nobody looked up to see who was next, her eyes widened and she gasped. She slowly walked towards him and then ran. She wrapped her arms around him and hugged him really tight. The blonde haired boy did not know what to do but placed his hand on her shoulder. She pulled away from him and placed her hand on his cheeks.

"You're okay…" She whispered and everyone stared at her like she was crazy. Then tears start to fall from her eyes right down her cheeks. "What?" She wiped her tears and looked at them. "Why…?"

"Don't pretend to cry and have a heart, Xiaka." Xahna warned her.

"But…" She was about to explain but the silver haired woman glared at her and she went quiet.

"His name is Roxas by the way." Xuko added.

"I'm sorry Roxas, it's just…" She took a deep breath and looked at him. "You remind me of someone dear to me." She smiled even though deep inside it killed her.

Eventually, everyone left to go to sleep but Xiaka and Xuko stayed there. The brown haired male crossed his arms and huffed.

"You remember everyone but the most important person to you, huh?" He asked.

"Kou, is that really you?" She asked and he gasped. "It's been so long and you've changed so much that I almost didn't recognise." She turned to him. "How can I forget my best friend?" Xiaka smiled and he smiled back.

"I didn't think you'd still remember." He said.

"You grew a freakin' beard and you're as tall as a tree." Xiaka stated. "Cut me some slack."

"Yet you're still shorter than me, shortie mc short shorts." He smirked whilst poking her forehead and she punched his stomach whilst pouting.

"Shut up." She cried and he wrapped his arms around his stomach.

"But you're freakishly strong." He laughed.

Instantly, the young Nobody wrapped her arms around him tightly and hugged him. His cheeks turned bright pink at this and he gulped. He slowly wrapped his arms around her whilst holding her closely.

"I missed you so much, Aika." He whispered.

"I missed you too, Kou." She mumbled.
