A/N: Tada! A new Yu Yu Hakusho story! No this has nothing to do with the other one's I have written.

So Yu Yu hakusho belongs to Yoshihiro Togashi, the story line doesn't follow the actual story line in YYH... for the most part. Sophie, Mattie and any side characters that show up belong to me!

Please Enjoy the story!

Oh!!! And I have to get two reviews or more before I post a new chapter. So REVIEWS!!!!



"Can you hear me?"

"Loud and clear Sophie." Was the reply. "Are you sure this is the place?"

"Yeah I'm sure Mattie. This is where the information leads us too." The voice now named Sophie answered.

Mattie sighed heavily as she brushed her hair from her face. "Here goes nothing…" She murmured as she reached for the door.

"Stop nagging me you hag!" A male's voice shouted as the door ripped open in front of Mattie.

"Ah…" She started as she pulled her hand back. "I'm sorry."

The boy stopped and stared down at the five foot five girl. "Can I help you?"

"Mattie, the information I've got says this boy is Yusuke Urameshi. This is definitely the right place." Sophie's voice buzzed in Mattie's ear.

"Okay…" Mattie said under her breath as she shifted her hair over her right ear.

"Yes…" She said louder to the boy in front of her. "I was looking for the Urameshi family."

"Yusuke, who's at the door?" A woman asked as she pushed up against the boy. "Oh!! I was wondering when you would finally come to see us!"

Mattie smiled at the new woman. "I'm sorry it's taken me so long Atsuko. Japanese isn't my first language so I got a little lost."

"Mom, you know this girl?" Yusuke asked as he looked at his mother.

"Of course I do!" Atsuko answered. "Yusuke, I would like you to meet your sister, Mattie Herrmann."

Yusuke's eyes looked like they were about to pop out of his head. "My what?!?"

"Half sister." Mattie explained while Sophie's laugh echoed in her right ear. "I'm your half sister."

Yusuke's attention turned back to the girl in front of him.

She was average height but her body shape was close to the hour glass many women sought after; a larger chest a small curve in at the waist and round hips. Her eyes were a bright spring green and her hair was a bubble gum pink; she looked nothing like Yusuke.

"Are you sure…?" He asked as he stared at her.

She smirked and shook her head back, moving the hair on the right side of her face out of her eye to reveal an intricate tattoo under her eye. It was lines that crisscrossed each other with one long one that ended on the top of her cheek with a snake head.

"I'm sure. I did the research and you and I have the same father." Mattie answered.

"Excuse me but I did the research. You wouldn't even know how to use a computer." Sophie answered.

"I've gotten better with them…' Mattie muttered under her breath.

"What did you say?"

"Ah…" Mattie blinked. "Sorry I said I wonder if this was the right thing."

"Oh!" Atsuko cried. "You shouldn't be standing out there. Come in come in!"

"Thank you." Mattie smiled and slid in past Yusuke.

Yusuke watched her for a moment then shook his head and closed the door behind him; he was going to find out about this new addition to his family.

0-0-0-0-0-0-0-0

The door to the small apartment opened and Mattie slipped in, closing the door quickly behind her.

"So…? How did it go?" A female voice questioned behind a wall of electronics.

"It was weird, but thanks to you I had all the documents I needed to prove to them that I was really Yusuke's half sister."

A girl stepped out from behind the electronic wall to sit down a chair in front of it to stare at Mattie; her deep blue hair was pulled back into a messy braid and her amethyst colored eyes bore into Mattie.

"It helps that you were actually related to him and we didn't have to fake any of it."

Mattie nodded as she turned around and pulled off her shirt; and intricate tribal tattoo covered her entire spine with a butterfly that covered half her back. "I'll be starting school with him and his group of friends. His little girlfriend Keiko demanded that I did."

Sophie nodded as Mattie slipped on a tank top and turned around; the top of the tribal tattoo on her back came over her shoulders and ended on her front, one of which led into another tribal design that trailed down her arm with two lilies integrated into it. "What about all those? You thinking the sleeves of the uniform will show them off?"

Mattie shrugged. "I'll just wear the long sleeve shirts."

"And the one on your face?"

"Make up."

Sophie nodded again and got up. "I'm going to give you a better recording device and ear piece."

"What you're not coming with?"

"We'll see, someone needs to watch surveillance."

"Oh but the boss gave us these." Mattie jumped up and ran to her bag. She dug through tossing her clothing left and right until she found what she was looking for.

Why oh why did they put me with bubble gum? She's such a scatter brain. I don't even see how she got through so much to even get assigned this job. Sophie thought to herself as she waited on Mattie.

Mattie turned around with a smile. "Here one for you and one for me." She handed what looked to be a compact to Sophie.

Sophie opened hers up to see that it was, in fact, a compact. There were two squares of blush, eight squares of eye shadows and two squares of lip gloss with the slots for the brushes.

"Make up? The boss gave us make up." Sophie looked up at Mattie to see her still grinning. "What are you so happy about?"

She walked over and pushed against one side of the compact. The makeup flipped up to reveal a tiny keyboard. "It's a hidden computer, when you turn it on the screen lights up behind the mirror. It's a super computer, almost as smart as the stuff you got back there. The boss figured it would be good for us to have things we could take with us into the school. Plus…" She closed the makeup and pointed to the small logo on the left corner. "If you click on that it will take a recording with sound and…" She moved Sophie's finger to the back. "That one will take a picture."

Sophie blinked. "Damn. He thought of everything."

Mattie grinned again. "Yep! Now we both can go to school!"

Sophie cringed inwardly, she could hardly handle Mattie as much as they were seeing each other already, and she didn't know how she could handle more.

Well at least I'll be able to keep her in line. Maybe she'll stop being such a scatter brain when I'm there with her. Sophie thought.

"It's going to be fun." Mattie said as she flopped back onto her bed.

"Yeah…" Sophie answered. "Fun…"
