YYH and the Mysterious American

Summary: A mysterious American transfer student shows up at Saryaski High School

And seems to have a secret that the new demon is itching to get his hands on. Can the spirit detectives protect her and stop the demon before it is too late.

A.N.: Sorry about any mistakes on names and such, if you find any mistakes feel free to include them into your review.

Nikki: I think they get the idea by now so get on with it!!!

Me: I still need to include the disclaimer so the hordes of lawyers do not come after me *knock knock* oh no they're here run away *runs right into a wall* ooooo, that hurts o_O

Nikki: She doesn't own YuYuHakusho or any of the characters; she does own me and any characters not in the show. Now onto chapter one…

Chapter one: The new girl

"Mother, I can't find my keys any where," a fifteen-year-old girl yelled down to her mother.

"Did Tai maybe hide them again," her mother yelled back to the girl.

The girl looked for Tai seeing him also missing, "Um - probably…"

The 5'6" tall girl finished dressing into her new school uniform of Saryaski (sorry if it is spelled wrong) Junior High School. The skirt was blue pleated and came down to her knees and the white shirt had a sailor collar with a scarf that tied. She quickly threw her silver hair back into a ponytail as she made sure everything was neat and in place. She grabbed her school bag from the desk and ran out of her bedroom tripping over an unpacked box on the floor.

She already hated this school for making her wear a skirt. She was more comfortable in jeans and a tank top, which is why she planned on changing after classes. The girl ran into the kitchen grabbing an apple from the fruit bowl and finding her keys also there.

"Honey you need to eat more than that," the girl's mother said.

"Sorry mom, running late, no time, gotta go, see you later, will be home late, exploring," she said in one breath as she left through the front door.

The girls mother shook her head, "Still as scatterbrained as ever and get back in her young man."

A midnight black fox slunk back into the living room after giving the woman the evil eye.

The fifteen-year-old American girl peddled her bike down the sidewalk praying she wouldn't be late for her first day of school. She was the front steps of the school come into view and saw that the students hadn't even began to filter into the pristine school building. She saw someone step right in front of her and barely missed creaming a boy in a green school uniform and slicked back hair. She swerved and parked the bike onto the bike rack. She glanced back at him seeing his gaze fixed on hers.

She locked the bike up and grabbed her bag from the handlebars. She felt someone grab her shoulder and she proceeded to flip them onto the ground twisting their wrist in the process. When she looked at them, it was the same boy who she nearly creamed with her bike when he stepped out in front of her. She let go of his wrist and stalked off without saying sorry. It served him right, maybe that will teach him to not sneak up on people. As she went inside an orange haired boy stood over the black haired one.

"Hey Urameshi, whatcha doin' down there. Someone finally flatten ya," the orange haired boy said laughing loudly.

"Shut up Baka," Urameshi said as he stood up his back aching from hitting the concrete, "Some Baka female got all huffy when I touched her shoulder and she flipped me, just like I weighed nothing."

"Oh good one, Urameshi, getting flattened by a girl will be something I'm sure everyone would like to hear. The Great Urameshi number one punk at Saryaski Junior High School beaten by a girl," the orange haired by continued laughing very loudly.

"If one word gets out about this Kuwabara I will knock you into the Makai and back," Urameshi threatened.

Kuwabara had his hands up in defeat as he backed away from his friend's murderous glare, "N-no problem… Gomen-nasai."

"Come on, I can't believe Keiko actually talked me into going to school today," Urameshi said as he put his hands into his pocket and huffed into the school and to his home room.

As he walked in Keiko waved for him to sit next to her. He sat down and proceeded to stare out the window uninterested in the class occurring around him. He saw the silver haired girl walk-in gracefully and stands at the front of the room. Yusuke Urameshi focused hi gaze onto her, now seeing who flipped him. The girl was 5'6" slim figured, long silver hair that even in a ponytail still reached her lower back. She glared at Urameshi before smiling once again.

"Class I want you to welcome your new classmate Nikita Mairoushi from America. Ms. Mairoushi you may take a seat by … Keiko (sorry forgot her last name)," the teacher said.

"Arigato Ms. Mashi-sensai," Nikita said as she bowed to the teacher.

Nikita went and sat down next to Keiko who had her hand raised so she would know which one was she. As the American sat down she gave Yusuke a death glare once more before taking out her schoolbook.

Me: she is really giving Hiei a run for his money now isn't she,

Hiei: Do it once more and meet my katana,

Nikki: Hey back off shorty, gives the death glare once more and gets ready to beat him senseless,

Me: oh well back to the story

School soon passed by quickly and Nikita walked out into the beautiful weather after changing into her jeans and tank top. She heard footsteps behind her and continued unlocking her bike chain.

"Excuse me," a female voice sounded behind her.

Nikita stood up, turning to face a girl of moderate height, brown hair, and brown eyes. She smiled at the girl knowing her as Keiko from homeroom. Nikita set her bag onto the seat of the bike and eyed her cautiously.

"Yes?" Nikita asked.

"I know your new here and I wanted to invite you to my parents noodle shop to meet some of my friends," Keiko asked.

Nikita shrugged her shoulders, "Yeah okay. And I'm sorry about coming off as a cold heartless person, but bad day."

"It's okay," Keiko said as she waited for Nikita to grab her bike off the bike rack, "Where do you live anyway?"

"Oh, quite away that way," Nikita said pointing to the north.

"Oh wow you must live in Suiichi's neighborhood," Keiko said as they began to walk towards the noodle shop.

"Who?" Nikita asked.

"Don't tell me you haven't met Suiichi Minamino yet. Tall, long red hair, beautiful green eyes, quite handsome, makes most every girl swoon over him," Keiko said.

"Um now that you mention it, I live next door to someone who fits that description, but haven't had the liberty in meeting him yet," Nikita said.

"Why aren't you attending his school then?" Keiko questioned.

"Well first I can't afford it, second I'm too lazy to want extra work even though I have the brains for it, third then I wouldn't have met you," Nikita said smiling at Keiko's expression.

"You sound like my boyfriend, Yusuke Urameshi. Only I have to threaten him with bodily harm to even get him to go to school. I don't understand it, if only he would put in just an ounce of effort that he usually puts into beating someone up then I would be happy, but…" Keiko explained.

"Well we all have our down falls," Nikita said staring into space thinking about how many times she had beat up a boy for just looking at her wrong at her old school in America.

The question and answer talk went on for another fifteen minutes only stopping when they reached Keiko's parents noodle shop. Nikita locked her bike up out front before following the shorter girl into the warm restaurant.

"Mother, Father I'm back," Keiko said and soon was enveloped in a hug by her parents.

"Who is this honey?" Keiko's mother asked (sorry don't know their names)

"A friend from school," Keiko said.

"And does your friend from school have a name," her father asked.

"My name is Nikita Mairoushi from America. I just moved here with my mother," Nikita said bowing to the two adults.

"Pleasure to meet you," Keiko's mother said.

"Hey Keiko," Urameshi called out as he came in.

"Yusuke!" Keiko said as she ran up to him dragging Nikita behind her.

"What's she doing here?" he spat out.

Nikita glared at him, her eyes threatening bodily harm, "I'm here because Keiko invited me here."

"Nikita this is Yusuke Urameshi," Keiko said still smiling not at all fazed by Nikita's death glare at Yusuke or his returning ones that were beginning to falter.

"Keiko please call me Nikki. Nikita is so formal," Nikki said.

"Oh um - sure," Keiko said, "Where are the others. I want to introduce them to Nikki."

"In the park. Come on," Yusuke said as he left the noodle shop.

Nikki unlocked her bike and walked next to Keiko who walked next to Yusuke. The trio made their way into the park and soon met up with three other teens lounging on a park bench. The conversation they were having came to an abrupt stop as Nikki came closer. The orange haired boy started laughing when he saw her. The red head raised an eyebrow in puzzlement and the blue haired girl just smiled at Nikki.

"Hey guys this is Nikita Mairoushi from America," Keiko began, "And that's Kazuma Kuwabara, Botan, and Suiichi Minamino."

She pointed at the orange haired boy, then the blue haired girl and finally the red headed boy.

"Pleasure to meet you," Suiichi said in his cool, calm, quiet voice, "You wouldn't happen to be my new next door neighbor would you."

"Actually I am," Nikki said smiling just enough to cause her amber eyes to sparkle.

"You're the girl who flattened Urameshi aren't you?" Kuwabara stated while laughing like a hyena.

Nikki smiled slyly at the tall boy before grabbing his wrist and throwing him across the park, a good ten or twenty feet away. Urameshi stood in shock at what happened. Suiichi watched the girl with a trained eye trying to find out what she is hiding. Botan and Keiko went to help Kuwabara up to his feet. A hidden person watched in amusement from the tree near the woods at the downfall of the Baka Ningen that he hates. Nikki heard the hidden person smirk before looking up into the tree.

She saw a short male about sixteen or seventeen with spiky black hair that had a white star burst on the front part. He wore a white bandana on his forehead, black pants, black long sleeve cloak like shirt, and a white scarf. He focused his crimson eyes onto her amber ones before jumping down to the ground. He carried a katana that Nikki knew had probably killed many. She approached him intrigued by his sudden presence.

"Hello, my name is Nikita Mairoushi," Nikki said.

"Hn," was all the response she received.

"Sorry about that. His name is Hiei Jaganshi," Suiichi said.

"I understand," Nikki said as she sat down on the bench.

She pulled out a sketch pad from her bag as well as a pencil box. She opened up the pad to an empty page and began to sketch a drawing only occasionally looking up to get a referrence on something. By the time she was almost done Kuwabara was on his feet looking for Nikki. She ignored him as he stood in front of her blabbering on about how he was going to make an exception to his rule about not fighting girls. Nikki set her pad face down so no one could see what she was drawing and then stood up.

"Just so you know, Kazuma, I do not wish to fight you . The reason why I threw you was to teach you a lesson to not laugh at others misfortunes," Nikki began her voice low, calm, and resonating power, "I did not intend to flip Yusuke, but I did it because he startled me. I do not like anyone touching me without my consent. Even a simple handshake could result in you getting a broken arm. Do I make myself clear, Kazuma."

"Yes ma'am," he said sitting down.

Nikki grabbed her bag and hoped onto her bike peddling away from the park as fast as she could. She needed to get home to cool down before she lost her temper and control over her spirit energy. If she ever let that slip even a little there would be people trying to kidnap her for the energy.

Yusuke and company watched her back as she biked away. Kuwabara, Botan, and Suiichi all shivered as a wave of spirit energy washed over them. Hiei took the time they were preoccupied to grab the forgotten sketch pad from the bench.

"Okay, did anyone else feel that?" Kuwabara asked his voice quivering from the verbal onslaught he had received.

"Yes I did," Suiichi said thoughtfully.

"Kurama?" Urameshi asked.

"I think Nikita is concealing a lot of spirit energy. Even more than you Yusuke. When she let her control slip it was almost like a tidal wave of energy was released before the dam was brought back up," Kurama said.

"I think I will go talk with Koenma to see if the Foreign Division of Affairs has anyone registered with high spirit energy," Botan said as her oar appeared.

The ferry girl flew into the sky seated on the oar. Soon she was out of sight and the others began heading home. Hiei and Kurama were the only ones left in the park as the daylight failed and slipped into darkness. Kurama spotted the black sketch pad in his hands as he stared at one of the drawings.

"Hiei," Kurama began, "Is that Nikita's sketch pad?"

"Hn," was all Hiei said.

"It is," Kurama said as he snatched it from the fire demon's grasp.

He looked at the last drawing done and saw it was of him and Hiei as they were standing in the park earlier. It was perfect down to the last thread of Hiei's scarf. Kurama was amazed at the speed in which it was completed. His curiosity got the better of him and he looked at the other drawings. There were many of a fox, none colored of course, and even a few of him which surprised him. He closed it up and started walking home. He would drop it off to Nikita on the way. Hiei followed also curious it seemed about the Ningen girl.

"Hiei why did you take the sketch pad?" Kurama inquired.

"I was curious about what she was drawing," he said shortly. (Me: I know Hiei is kinda OOC so sue me,).

"And?" Kurama continued.

"She draws perfectly," Hiei said, "And if you repeat what I said I will cut off all your tails and use them as a katana warmer."

Kurama put his hands up in defeat, "I will not say a word on threat of de-tailment."

Hiei jumped into the tree by Kurama's house as Kurama walked away. The tree happened to be in between Kurama and Nikita's house. Kurama rang the door bell and waited. Soon the door opened revealing a young woman with black hair pulled up in a claw clip and brown hair. She was no taller than 5'0" and slightly on the chunky side. She smiled at the teen before ushering him into the house.

"Good evening Mrs. Mairoushi. I do not want to interrupt you, but Nikita left her sketch pad at the park."

As if on cue Nikita yelled down the stairs, "Mom have you seen my sketch pad."

"Actually dear come down. I believe you have a guest," Reya Mairoushi called back up.

"Mother what are you saying. I haven't invited anyone … oh my, Gomen," Nikki said as she came down the stairs and saw Suiichi Minamino standing in the front hall.

"Now dear don't be rude, introduce your friend," Mrs. Mairoushi said.

"Sorry, Suiichi my mother Reya Mairoushi, Mom, Suiichi Minamino," Nikki said.

"You must be Shiori Minamino's son," Reya said smiling. (Me: I'm not sure what her exact spelling is so just deal)

"Yes I am," Suiichi said.

I thought so. So polite. Your mother came by earlier to welcome us," Reya said, "Would you like to stay for dinner?"

"Um… okay," Suiichi said uncertain.

"Very good. Dinner will be ready in an hour. Hope you like taco's," Reya said as she disappeared into the kitchen.

"Gomen, she gets very excited when a friend of mine stops by considering in America I had a whole total of one," Nikki said as she walked back up to her room.

Suiichi followed her up the stairs and into the bedroom that was even with his own. The room was painted dark blue and looked like the sky right before the dark night rolls in. There was a whole star system on the ceiling. There were also shelves of books in English and Japanese against the wall and porcelain dolls smiling down from other shelves above the bed. The bed itself was full sized with celtic bedding done in the same dark blue as the walls. The desk contained a laptop open and logged onto an instant messenger service. Lying on the desk next to the laptop was a black fox with silver eyes. He realized that it was a Youkai, a Kitsune only the can have eyes that color or gold as Youko liked to sport sometimes.

"Suiichi isn't that Hiei in the tree outside?" Nikki inquired about the short fire demon in the tree.

"Um… yes it is," Suiichi answered.

"Would he like to join us for dinner?" Nikki asked.

"I am not sure. He is usually not very social, but I will ask," Suiichi said.

"I'll ask him," Nikki said opening the window, "Hiei would you like to join me, Suiichi, and my family for dinner?"

"Hn," Hiei answered before leaping into the window.

"I'll take that as a yes then," Nikki said sitting down on the computer chair, "Sit down. I and Tai will not bite."

The black fox watched the two Youkai with interest as they sat down on the bed or at least Suiichi sat down. Hiei sat on the window sill looking bored.

"So why did you stop by anyways," inquired the American, "It's not like we are best friends. We just met today."

"You left this at the park," Suiichi said handing the sketch book to the girl

"I was wondering where it went off to," Nikki said, "So how did you like them?"

Suiichi nearly fell off the bed at the question, Hiei just smirked, "Ho-how do you know…"

"Oh come on I am sure curiosity got the better of you and you looked," Nikki said, "I don't mind, really. I hope you don't mind that I sketched you guys."

"Not at all. They are beautiful, but how, if we just met, did you sketch me?" Suiichi questioned.

"I saw you briefly when I moved in and memorized your face. I can do that, with one glance I can tell you exactly what you were doing, wearing, eating, whatever at that time. Even months later," Nikki explained.

"Hn, very useful," Hiei said, "Especially if you need to hunt them down."

"Wow more then a 'Hn' for a change. Are you falling well. Do I need to call a doctor," Nikki said laughing.

Suiichi was trying not to laugh at the fire demon, but failed miserably. Hiei gave them both his famous death glare (Nikki: see I didn't steal it completely from you,) as they watched him. Nikki grabbed her pillow and hit the fire demon in the face. His eyes grew wide and he took the pillow this time hitting Suiichi upside the head. Nikki was laughing hysterically when he felt a pillow hit her as well. She saw Suiichi holding it in his hands.

Both he and Hiei were advancing on to her determined to get her back. She backed away slowly until her back hit the wall. She then grinned slyly at them and shielded herself from the soon to come pillow blows. Just as they were going to hit her Reya called upstairs.

"Nikki honey dinners ready," Reya shouted.

"Okay Mom, and set one more plate I have another friend who will be eating dinner with us," Nikki shouted down.

"Sure thing," Reya said.

"Come on guys dinner won't wait for us, especially when my hungry half brother gets home," Nikki said.

The three friends went down stairs into the living room and then the dining room. Trhere was a boy about twenty five or so sitting at the table waiting on them. He was about 5'2" with short black hair and hazel eyes. Nikki sat down across from him, Suiichi next to him, and Hiei next to Nikki. Reya sat at the head of the table. Soon each person had a plate full of food and began eating.

"Hey little sis, introduce your friends," the twenty-five year old said.

"Sure, the red head is Suiichi Minamino our next door neighbor and the black haired one is Hiei Jaganshi. Guys this is my half brother Ryou Muiishu. He has his father's last name. When I was born Mom was already remarried to my father Daashu Miaroushi hence were half siblings," Nikki explained.

"Thank you for explaining our insane family past," Ryou said chuckling.

"Sure thing. Anyone for seconds," Nikki asked.

"No thank you," Suiichi said.

"No," Hiei said.

"Well then folks I think I will excuse myself and these gentleman," Nikki said getting up from the table.

She carried her plate and her guests plates to the kitchen. She met up with Suiichi and Hiei in the front hall. She said good-night before closing the door. Kurama walked with Hiei to his house next door. Hiei once again sat in the tree waiting for Kurama to go to his room and let him in. Soon the window opened and Hiei leapt in silently landing on the floor. The short fire demon sat down on Kurama's bed waiting on the Kitsune to speak.

"Hiei why did you join in the pillow fight? It just seemed like something so - um - Ningen would not interest you," Kurama said point blank.

"Hn, do not know actually," Hiei responded, "And do not let the Baka or Urameshi know what I did tonight."

"I wouldn't dream of it, honestly," Kurama said sincerely.

"That goes for Youko as well," Hiei said.

"Sure, promise," Kurama said again, "And now if you don't mind I would like to go to bed."

"Hn," Hiei said as he leapt back into the tree.

Kurama chuckled to himself as the fire demon left the room. He changed into his pajamas and climbed into bed falling almost instantly to sleep. Hiei watched the girl as she also slipped into bed. He was amazed at how beautiful she looked as the moon light hit her. He mentally slapped himself for those thoughts running thought his mind. He let his Jagan eye search her mind, but found it guarded well by a barrier.

'Hmm, interesting. I will need to keep a close watch on her,' Hiei thought to himself.

He saw Nikki shift to a sitting position and search her room for the prying mind. Her gaze fell on the fire demon sitting in the tree and her eyes narrowed suspiciously. He felt someone try to enter his mind and his Jagan eye glowed as it shielded him from the prying mind. Soon it stopped and Nikki's eyes went wide in surprise. Hiei jumped down from the tree and using his demon speed headed to the Makai to sleep.

Me: So how was it, hopefully good enough to review. So people please read and review. 5 reviews and I will update the next chapter.

Nikki: come on people be nice and tell her that it is excellente'. so I can't speak French so sue me.

Hiei: you are mine. Using my death glare will earn you a one way ticket to the Makai the hard way.

Nikki: bring it on shorty *pulls out a katana*

Hiei: Hn, *pulls out his katana and goes after her*

Both: you are dead!!!

Yusuke: What is going on in here I am trying to sleep, *runs away in fear as both Hiei and Nikki chase him down*

Me: Well while they destroy my bedroom * dodges a flying book* I will begin the next chapter, Later days…

Next episode: Koenma finds out about Nikki's spirit energy, Nikki gets attacked, and the Spirit detectives find out about a new demon. Guest appearances by Genkai and Yukina.
