Author's Note:

This is my first fanfiction that I decided to put up on here. Please no flames and I'll take criticism, but I don't want to hear things that will make me feel like a crappy writer. Also no cracks about the grammar, I kind of suck at it and I already had a friend edit it for me.

Exorcist

Chapter 1: The Beginning

In the Black Order Headquarters, a young 15-year old girl with long brown hair tied into low pig tails was seen walking out of the Ark. She wore a light blue and white winter kimono since it was snowing from where she came from. Her name was Koyuki Shiraiyuki, the newest Exorcist of Japan who came to join the Black Order. Right behind her was Allen Walker.

"Welcome to the Black Order," he said with a smile on his face. Koyuki turned towards him and smiled back as she turned her gaze towards everyone in the room. A lot had happened for her to arrive there, and it all seemed to go by so fast…

- 1 year earlier -

Early Christmas morning came and Koyuki was searching for her present. The Shiraiyuki family lived in a small village in Japan. The village was poor, but everyone was able to get through life. The morning was quiet and peaceful with snow falling gently outside.

"Where did nii-san hide it?" she muttered to herself as she searched the closet, trying to be quiet so she wouldn't wake anyone up. Her older brother, Satoshi, had told her about the present he bought for her a few days ago and she had been searching ever since. Satoshi was three years older than her, and was apparently very good and hiding things.

"Looking for something?" Koyuki stiffened and slowly turned towards the voice.

"M-Morning nii-san!" she said with an innocent smile.

"Yeah…You were looking for your present again weren't you?" Satoshi asked, crossing his arms.

"Maybe…" She averted her eyes and put her hands behind her back.

Her older brother smiled and walked inside the closet, moving the clothes so that he could get to the very back. Somewhere in the wall was a secret door that had a secret compartment where he hid her present. He took it out and handed it to his sister.

"Merry Christmas."

A big smile grew on Koyuki's face as she took the present and started tearing off the wrapping paper. "Arigato nii-san!" Underneath the wrapping paper was a box and when she opened it, there was a pair of black fingerless gloves.

"I thought you could use it for archery. You always get those blisters every time you go and practice," he said, pointing to one of them on her palms. "Plus, it looks good on you."

"You're the best, nii-san." She threw her arms around her older brother, giving him a big hug as she remembered something. "Oh right! I need to give you your present! Wait here!" She ran to her room and dove under her bed. She came back with a poorly wrapped slim stick-like object. "Sorry about the wrapping. Don't tell mom and dad what I got you. They'll probably freak out."

Satoshi raised an eyebrow at the last part of what his little sister said and took the present. Unwrapping it, his eyes widened. "Koyuki! Where did you get this?!" he exclaimed in surprise, holding up the present that was now revealed to be a katana. "You didn't steal it did you?"

"Of course not! I'm not a thief! Now keep your voice down or else you'll wake them up." She said. "I got it from the blacksmith. I've been running errands for him all month and he rewarded me with that."

"Oh… thank you." He smiled at his sister and ruffled her hair before giving her a hug.

Koyuki had no idea that she held on to something much more precious than it seemed for so long…

- 11 months later -

Ever since last Christmas, it never stopped snowing even when winter passed. In the little village there was a lingering feeling of despair. A funeral was in session as the Shiraiyuki family gathered around a black coffin. All were present except one. The head of the Shiraiyuki family had contracted an illness from the weather, and had died. It was hard on the rest of the family, but over time they managed to live on.

A couple of weeks later, Koyuki was in the yard practicing her archery, wearing her gloves. The weather was calm today and just a light sprinkle of snow fell from the sky. Each arrow she shot hit the bulls-eye. Lately she had been thinking about how her mother had been acting strangely. Koyuki and Satoshi were able to move on from their father's death after a while, but their mother was different. She was depressed after the first week without their father. Sometime during the second week, their mother had stopped mourning and crying. Instead, she turned very quiet.

'I hope mom is okay…' Koyuki thought as she released an arrow, hitting another bulls-eye.

Her mother came out from the house and approached her daughter.

Hearing the snow crunch underneath her mother's feet, Koyuki stopped and turned towards her. "Hey mom," she said with a smile.

Her mother said nothing as she looked at Koyuki's gloves.

"Something wrong?" she asked when she got no response.

"I…found…it…" Her mother said as she grabbed Koyuki's arm.

"M-Mom? What are you talking about?" Koyuki asked. "Ow! You're hurting me! Let go!" She pushed herself away from her mother.

Once Koyuki was released, her mother hunched over. Her back seemed to split open, and something came out of her back, a metal machine monstrosity. Once revealed, it aimed its guns right at Koyuki.

Eyes wide, Koyuki let out a scream as she started running away from the monster. She grabbed some arrows and shot them at the monster, but had no affect since its body was made of steel. "S-Someone help!" she screamed, completely terrified.

The monster started shooting at Koyuki, but missed. The bullets landed behind her, making a small explosion as snow and dirt blasted out, making her trip and fall. One hit from those bullets would turn her to dust.

"Koyuki!" Satoshi appeared and leaped at the metal monster, swinging his katana at it. It had no effect, but he was able to push it away from his little sister. "Are you alright?" he asked.

Koyuki nodded, shaking a bit. "M-Mom…S-She turned into that - that monster!"

Satoshi's eyes widened in shock and made a grab for Koyuki's hand. "Come on, we gotta get out of here." Satoshi started running away from it dragging his sister along. He needed to get Koyuki away from that thing. It was his job as an older brother to make sure she was safe.

No matter how far they went, the monster chased after them, firing deadly bullets.

They eventually started to slow down. "Nii-san…I can't run anymore…" Koyuki panted as she came to a stop.

"We can't stop now, that thing will kill us!" Satoshi said, trying to make his sister move.

As soon as it caught up to them, it targeted Koyuki and it fired a bullet at her.

Satoshi saw the bullet and quickly pushed his sister out of the way, taking the hit.

"Nii-san!" Koyuki quickly scrambled to her brother and saw pentacles starting to appear on his body.

"R-Run…Hurry…" Satoshi said, feeling weaker and weaker as the poison spread.

"I'm not leaving you…" Koyuki held her brother close to her as she looked at the monster, guns poised and ready to fire. She closed her eyes and waited for the bullets to hit her. She heard the gun shots and flinched, holding her brother tightly. She felt no pain and wondered why. Was she already dead?

"Hey, are you okay?"

Koyuki's eyes opened and she saw a boy with his back turned to her. He had white hair and was wearing a black and red uniform with a white coat. His left hand was some kind of black claw.

"Yes, but my brother…please save him!" Koyuki pleaded to the boy.

He looked back, showing his cursed eye which was black with red circles. There was a strange red star above his eye, and a red line ran down his eye and to his cheek. On his eye was a strange glass lens attached to a gear. Koyuki let out a small gasp when she saw his eye. He then turned his attention back to the machine monster. "Sorry. It's too late." He swung his black claw at it, destroying it in one swipe.

"Sorry Koyuki. Seems like I won't…be around…anymore. Live on…for me, okay?" Satoshi said, a smile on his face before he closed his eyes and his body turned to dust. A gas released once his body had crumbled.

"NII-SAN!!" Koyuki shouted before the boy put a hand over her mouth and nose.

"Don't breath it in, the gas is poisonous." he said as he started dragging her away from the gas. "I'm really sorry…"

Tears ran down Koyuki's cheeks as she screamed her brother's name into the boy's hand. She had lost everything now. Everyone was gone…dead.

The boy waited until Koyuki calmed down and the gas was gone. "My name is Allen Walker. I'm an Exorcist. The monster that attacked you was an Akuma, made by the Millennium Earl." Allen explained everything that had happened to Koyuki. He tried to comfort her since she had lost two of her family members.

"Since that Akuma was after you, you might have an Innocence with you. Would you like to become an Exorcist and fight against the Millennium Earl?" Allen asked.

"I…I'll need to think about it…" Koyuki said sadly, her brother was still on her mind. How was she supposed to go on living when her family was dead?

"Alright, but if the Earl shows up, don't take his offer and call me instead. I know your brother wouldn't want to become an Akuma and kill you." Allen said, leaving Koyuki alone for the time being.

Allen stayed in the village for about a week as Koyuki thought about his offer.

Sometime in the afternoon, Koyuki started looking for Allen. She found him at the small inn that was in her village. "I want to become an Exorcist for my family." She said as Allen smiled softly.

"Alright, pack your things and we'll leave as soon as we can."

Koyuki headed into the house, packing all the necessities she figured she would need. She also placed a picture of her father, mother, and brother before she was born into her back. It was a picture of them before she was born. Along with the picture, she packed the katana she gave her brother last year; the same one he used to protect her. A tear fell and she wiped it away before heading outside to meet with Allen. "I'm ready."

The two of them walked through the quiet village and stopped at some kind of white glowing portal. "Ladies first," Allen said, being a gentleman.

Koyuki looked at the portal with one raised eyebrow then looked over at Allen who had a gentle and delightful smile on his face.

"Don't worry, it's safe."

She sighed and stepped through, eyes widening in utter amazement. White buildings with many doors and flowers were in her sight. It was as if she was in another town, the place was so big.

"This is the Ark. We can travel practically anywhere in the world in an instant. Not exactly sure how it works, but I'm the only one in the Black Order that can control it," explained Allen as he started walking.

Koyuki followed him, looking around. She saw that the buildings were all similar with different numbers taped to the doors. Allen had stopped at a door that had a sign saying 'HOME'. He opened the door and motioned for her to walk through.
