So this is my very first story that I am putting up on a site for others to read so I am very extreemly nervous! I wont say to much about the story line, the title will explain itselffarther inthe story.

I apologise in advance for any bad english. And if I make any mistakes about the info of any of the yu yu hakusho characters then please tell me and I'll try to correct the mistake. But please do not flame!

The first one or two chapters might be a little le crap but it will get better I promise you!

Oh and dont get any ideas of HieiOC "hooking" up very quickly, I just don't think that fits well with Hiei-kun or Sachi-chan.

Owh yeah before I forget the name for the OC was chosen by Blokness aka GunslingerBlok (you should read her story) and maniac-nii-san and b4k4. Thank you for le help! -waves-

Disclaimer: I do not own yu yu hakusho, because if I did they would be living in my closet, but they do not so I do not own yu yu hakusho!

Footsteps sounded as a green haired girl walked through the empty hall while humming a happy tune.

Once the green haired girl had reached her destination she stopped walking and placed her hand on the door knob.

She swung the door to the trainingsroom open.

"Saaaachi-chaan!" Was heared through the trainingsroom were a young girl was training.

The black haired girl sighed and looked up at the green haired girl who called for her.

"What is it, shreeking Botan?" The girl replied with a lazy voice.

"Koenma wants to see you." The green haired girl named Botan said with a sing song voice.

"Now?"

"Yes now." Botan replied chirpy while looking at the black haired girl that was sweaty from all her training.

The black haired girl sighed again while bending down and grabbing her hoodie from the floor.

She put it on over her dark blue tanktop and pulled the hood up.

She walked to the doorway were Botan was standing and walked past her.

While walking through the halls the black haired girl turned the volume of her i-pod harder that was already on during her training.

The volume of the music was now so loud that it was hearable for the people around her.

"Do you have to have your music so loud?" Botan asked while following the black haired girl.

Her qeustion was ignored.

When they finally reached the door to Koenma's office the girl skipped the politeness part and opened the door without knocking.

She walked into the room, closing the door behind her and leaving Botan in the hallway.

"Damn it, Sachi, can't you knock?" A toddler behind the only desk in the office said annoyed.

"Not on your door, Koenma." The girl replied cold.

"You are so obnoxious." The toddler replied.

At that moment someone else who was also in the room cleared their throat drawing all attention to him.

"Right, I'll get to the point. I'll explain the reason why I called all of you here" The toddler said.

The black haired girl named Sachi ignored the little toddler and discreetly examined the other people in the room with her who she had noticed but hadnt payed attention to yet.

Infront of the desk in one chair was sitting a guy with slid back black hair and a green outfit on.

Next to him in the other chair was sitting a guy with long red hair and a purplish outfit on.

Dumbly standing next to them was a tall guy with a face that looked like it was banged into a wall to many times.

He had a blueish outfit on and orange like hair.

The last one was the shortest and was just like Sachi herself standing against a wall.

He had his arms crossed and had an annoyed exspression on his face, his clothing was black as was his hair.

The second he noticed her gaze on him his head turned to her and he glared at her.

Sachi felt uncomfortable shivers run up her spine and looked away from him without showing any emotion.

"Talking about wierd outfits…." Sachi thought.

The red haired one looked back at the girl who had entered Koenma's office a few minutes after them.

Her music from her i-pod which was hanging above her clothes was standing so loud that it drawed more attention to her then to Koenma who was talking.

The girl was wearing baggy torn jeans and a black hoodie with the hood pulled up, covering most of her facial features.

Two katana's were strapped to her waist and sais were strapped to her upperlegs and by the looks of it there were more weapons tight to her back under her hoodie.

Once Sachi noticed someones gaze upon her she looked up to see who it was only to have her bright blue eyes meet emerald eyes.

The red haired one's eyes widened when he saw the girls bright blue eyes from under her hair that covered most sight on her eyes.

Those were the most intense blue eyes he had ever seen.

When she saw his eyes widen she gave him a small almost unnoticeable smile in which the red head smiled back to in reply.

Koenma stopped talking when he noticed that most werent even listining to what he was saying.

This time it was the toddler who felt the need to draw all attention to him by clearing his throat.

When he got everybody's attention, he started talking again.

"Since your all so interested in each other….I'll introduce you to each other first. Sachi, this is Kurama." Koenma said while nodding towards the redhead.

"Kuwabara Kazuma." He continuede while pointing towards the ugly one with orange hair.

"Urameshi Yusuke." He said while pointing towards the guy with slid back black hair.

"And last, Hiei." He said while looking towards the shortest one in black that was leaning against a wall.

"Spirit detectives." Sachi mumbled.

"Thats right." Koenma replied.

"Guy's, this is Hisoka Sachi." The toddler contineude.

"Thats all very interesting information and all but whats the point in giving us this info?" Sachi asked while sighing a little.

"I was getting to that! Now as I was saying before when none of you were listening, there has been some disturbance going on in the Ningenkai."

Kurama, Yusuke and Sachi nodded, telling Koenma to contineu.

"I want you four spirit detectives to investigate on what exactly is going on and bring that information to me. When I have enough information and know exactly what is going on I will make a plan and sent you out to put a halt to this….disturbance." Koenma said.

Kurama nodded lightly.

"Sounds easy enough." Yusuke said with a grin plastered on his face.

"This is all very nice, but what does any of this have to do with me?" Sachi asked getting slightly irritated.

"Getting to that." Koenma's voice sounded with building annoyance clearly hearable. "You, Sachi are going to join them in they're mission."

"What! Have you lost your marble's!" Sachi exclaimed while her eyes widened slightly.

"Watch your tongue Hisoka!" Koenma said stern.

Sachi scolded, knowing she needed to watch her step when Koenma started referring to her by her last name.

"You will be very helpfull for the spirit detectives in this mission. You will all be living in the Ningenkai in the same house during this mission." The toddler said, regaining a little of his calm.

"Why? They can do this by themselfs, they don't need my help." Sachi sneered.

"And I work alone! And why the hell do we have to live in the same house?" Sachi finished, anger building within her.

"They might be able to this by themselfs but it will all go a lot faster if you are part of they're team during this mission." Koenma said while giving Sachi a knowing look in which Sachi averted her eyes from the toddler. "And you will be living in the same house because it is easier for me to contact you all when I need to. And you can get to know each other better so you will be able to work better as a team."

Sachi's glared intensly at the toddler.

"Sachi, could you please turn the volume of your music down a nodge." The toddler spoke highly irritated by the constant hearing of the music on the girl her i-pod..

The girl only looked at him and smirked.

"Arent you enjoying my music Koenma?" She asked calmly.

"No I am not, now turn the volume down!" The toddler spoke irritated.

"I'd rather not." Sachi said while closing her eyes calmly for a second before opening them again and smiling sweetly at the toddler.

Koenma turned red with anger which made Sachi her smirk reappear.

Suddenly Koenma calmed down and a wide grin spred across his face.

"Sachi why wont you take your hood down so the rest of the team can see what they're new teammate looks like." Koenma spoke amused.

Sachi's smirk faltered and her eyes turned to small slits as she glared at Koenma.

"Go on Sachi." Koenma said in a proud tone.

"Damn you Koenma, I don't really have a choice in this matter." Sachi thought to herself.

Sachi brought her hand up to her hood and brought her hood down.

Sachi has one clearly seeiable scar in a almost straight line starting right above her right eye and ending just a little above the end of her nose.

She had another scar that started right above the left corner of her upperlip and ended right past her bottomlip also in a almost straight line.

At the second her hood was down she saw all eyes were on her.

Even the short one who hadnt said a word yet looked from the corner of his eyes at the girl.

Sachi's anger towards Koenma only got bigger because of this.

Suddenly a gasp was heared through the now silent office.

Sachi looked up to see it had been the one with orange hair who was called Kuwabara Kazuma.

"I…It's a girl!" He exclaimed while pointing at Sachi.

Sachi smacked her forhead with her hand while Yusuke sighed and Kurama shook his head at the stupid remark of their teammate.

"Baka." The one named Hiei muttered under his breath.

"Shut up shrimp!" He replied trying to defend himself.

"What else did you expect Kuwabara, a guy with the voice of girl!" Koenma exclaimed.

"Well…." Kuwabara said, trailing of and scratching the back of his head.

"You are such an idiot Kuwabara!" Yusuke yelled.

"Stop the yelling please." Koenma said while sighing,

"This is going to be an interesting exsperience." Sachi muttered sarcastic.

"But she is going to stay in the same house as us?" Kuwabara asked.

"Yes Kuwabara, she is." Koenma said, growing tired of this conversation while rubbing his temples with his fingers.

"I wouldnt mind sharing my bedroom with you, babe." Kuwabara said while winking at Sachi.

Sachi's eyes widened in disgust.

"What about Yukina-chan, Kuwabara?" Kurama asked while smiling amused.

"Yukina? They know Yukina?" Sachi thought.

"Oh yeah." Kuwabara replied suddenly remembering.

"Gaah! You want me to live in the same house as this….this baka!" Sachi exclaimed while pushing herself away from the wall she was leaning against.

"I am afraid so." Koenma muttered.

"You must really hate me then. You really do suck as the Reikai's ruler, Koenma. I'll be brain dead within a week if I spent to much time around this baka!" Sachi sneered.

Hiei chuckled lightly at the girl her remark.

"Heey!" The orange haired exclaimed offended.

"She has a point there baka." Hiei said arrogantly while smirking slightly.

"Shut up shrimp!" Kuwabara yelled.

"I have only met him five minutes ago and he is already repeating himself." Sachi muttered quietly.

Yusuke laughed and Kurama tried not to but failed when hearing Sachi's remark.

"Ok, ok enough of this. I'll make a portal to the Ningenkai that will lead you to a forest that is fivteen minutes away from the house where you will all be staying." Koenma said.

Kurama was about to open his mouth to speak but Koenma cut him off.

"All of your stuff is already there." Koenma said right before making a portal appear.

Sachi pulled her hood back up before following the others through the portal.

Once they were all standing in the forest the portal closed again.

"So which way are we suposed to go?" Yusuke asked while looking around.

"This way." Sachi said while pointing in the direction of were the portal closed while turning the sound of her i-pod down a little.

"And how would you know?" Kuwabara said looking at you suspiciously.

"Because I have good eyes." Sachi replied dull.

Kurama raised his eyebrows at the girl.

"Fine, then don't believe me, I am going that way. You guy's go the way you want to go." Sachi said highly irritated before pushing her hands in her pants pockets and walking of.

Soon after someone caught upto Sachi and started walking next to her.

"I never said I didnt believe you." Kurama said from next to Sachi.

"You didnt have to, Kurama-san." The girl replied calm.

It stayed quiet between the two, only Yusuke and Kuwabara their verbal fighting was disturbing the silence.

"Are they always this noisy, Kurama-san?" Sachi asked.

"Unfortunatly yes." Kurama responded while nodding lightly.

Aexasperate sigh escaped past the young girl lips.

"It's kinda ironic how the great coldhearted Youko Kurama ended up in a human body, now so… Hmm how should I put it….emotional." Sachi said, looking deep in thought.

Kurama looked at the girl a little suprised.

"Does the fact that I have information about you bother you?" Sachi asked.

Kurama stayed quiet for a couple of seconds before answering.

"No, that doesnt bother me." He finally said.

Sachi gave a little nod.

"Then it's something else I said that bothered him. He is to smart for his own good." Sachi thought while a small grin played on her lips.

"Did I say something amusing?" Kurama asked while smiling lightly at the girl that was calmly walking next to him.

Sachi shook her head.

"No it's just..interesting." Sachi replied.

"I see." Kurama said, not pushing it any further.

"So since you seem to know pretty much about me, why not tell something about yourself." Kurama said kindly.

"What do you want to know?" Sachi asked without looking at Kurama.

"Give us some random info." Yusuke said while pushing himself between Sachi and Kurama. "You know, your age, where you come from, hobby's favourite collor."

"I am 17 years old. If you mean were I grew up, there wasnt really a place were I stayed long." Sachi said grinning with a distant look in her eyes. "Hobby's, I like writing, playing on my guitar, well bassicly almost everything that has to do with music I enjoy. I like training and doing missions. I like confusing people. Favourite collor I geuss blue black and purple. Is that enough info for you Urameshi Yusuke?"

"Just one more thing, what are your dislikes?" Yusuke said while grinning childishly.

Sachi looked up at the sky as she thought about what she should give as an answer. "There isnt really anything in particulair that I dont like. There are people that I dont like and I dont like it when people dont listen to me or not take me serious. Owh yes and I dont like it when people stab me in the back. But thats really all I guess."

"Thats rather interesting, you seem like an easy going person Sachi-chan." Yusuke said, trying to sound smart.

Sachi laughed a little.

"Dont count on it." She replied.

After about five more minutes of silence they finally reached the house.

When Sachi saw it her eyes almost bulged out.

"Damn." Yusuke and Sachi exclaimed in unison.

They looked at eachother and both laughed sheepishly.

"Thats like huge." Kuwabara exclaimed.

Sachi nodded.

They walked upto the house were Kurama found the key in the keyhole of the door.

"Thats rather stupid of koenma to leave the key in the door." Sachi said more to herself than anyone else.

With that Kurama opened the door and everybody walked in.

As everyone else looked around in awe Sachi immidiatly walked up the stairs in search of her bedroom.

Since Koenma said that all of there was already there she figured it would be in they're bedrooms.

Not much after Sachi had went upstairs the others followed.

Sachi sniffedby the door of the first bedroom in the hall and wrinkled her nose and shuddered.

"Thats Kuwabara's room." She said with a disgusted exspression on her face.

"Yay." Kuwabara exclaimed as he pushed the door to his bedroom open and waltzed into his room and slammed the door closed behing him.

Sachi had walked upto the next room and sniffed.

"Kurama-san's room." She said shortly before walking on to the door on the other side of the hall.

"Arigatou gozaimasu Sachi-san." Kurama said before opening the door to his room.

Sachi gave a short nod without looking back before sniffing by the next room.

Her face lit up.

"My room!" She said happely.

She opened the door and looked around in awe.

"Sugoii." She whispered.

"Wow thats really a nice room Sachi-chan." Yusuke said who was looking over her shoulder into her room.

Three of the walls were a dark purple while the last wall was black.

It had a glass door that led to a balcony and there was a door that presumable to Sachi led to a bathroom.

There was a two sixed bed in it with a night stand next to it, on one wall there was a big mirror.

There was a stereo in the room and a closet to put her clothes and stuff in.

Sachi looked at Yusuke for a second and then back at her room.

"You know, its impolite to just look into someones bedroom without they're premision. But I agree with you Yusuke-kun, it really is a nice room." Sachi said.

Yusuke chuckled lightly and patted Sachi on her shoulder before leaving her alone in search of his own room.

Sachi walked into her room and closed the door.

As soon as she did a whine was heared from behind her suitcasses.

Sachi looked up and quickly walked over and pushed some suitcasses out of the way to see a little cage with a small animal in it.

"There you are!" Sachi exclaimed happely.
