Summary: There's a very special girl. She is the Demon Slayer, charged with killing demons. But what happens when the very human Demon Slayer and the very demonic Hiei fall in love? Hiei/Original Character. Crossover with Buffy: The Vampire Slayer and Angel.

Disclaimer: I don't own Yu Yu Hakusho or the characters. Also, the fight scene between Hiei and Sahano is from Daredevil because I'm too uninspired to write my own.

AN: I was watching my Yu Yu Hakusho DVDs the other day while I was reading fanfiction, when I noticed something. Yusuke has Keiko. Botan has Kurama (or Koenma, whatever) and Kuwabara has Yukina. But where's someone for HIEI?! I love Hiei (maybe because he is so much like Vegeta off DBZ. . . ummm. . . Vegeta. . . ) and so I thought I'd make up a character for him. So enjoy my new character and my story.
Hiei sat with the rest of 'team' in the booth at the diner. His sister sat next to him, with her idiot human boyfriend next to her. Yusuke and Keiko were across from him, with Botan and Kurama next to them. Yusuke had both his arms around Keiko's waist and his face was buried in her neck. Kurama had his arm around Botan's shoulders, and she was resting her head on his shoulder. Even Yukina was holding hands with that stupid Kuwabara. Hiei thought he was going to be sick.

"I am out of here." He mumbled, getting to his feet and leaving the diner.
"Hiei. . ." Yukina whispered, looking after him.
"Let him go." Kurama advised her. "Hiei likes to be alone most the time. Frankly, I'm surprised he stayed as long as he did."
Hiei walked the streets in the dark, not knowing where he was going, not really caring. He stopped in his tracks when he heard someone scream. Hiei's first instinct was to keep walking. But he couldn't seem to ignore the scream.
"Damn you Yusuke and Kurama." Hiei cursed before running in the direction of the scream. The first thing he saw was a young woman struggling with a huge demon that had already grabbed her and had her lifted up off the ground.

Hiei drew his sword and attacked the demon, which dropped the girl. Instead of fainting, screaming or running, the girl flipped in the air and landed next to Hiei..
"Thanks for the help cutie. Wasn't necessary, but it's the thought that counts." The girl launched herself into the air and executed a perfect back spin kick that hit the demon in the head and dropped it.

The girl landed lightly, knees bent to absorb the impact and turned to face Hiei. He got one look at her and felt the breath leave his lungs in a whoosh. The girl facing him was the most beautiful girl he had ever seen, human, demon or otherwise. She was a full four inches shorter than himself and thin, with long emerald green hair that was pulled back and gorgeous ruby red eyes that drew him in. She was dressed in jeans, leather boots, a blue shirt that shimmered in the moonlight, a matching sapphire choker necklace and a black leather jacket.

"So what's your name cutie?" She asked Hiei, running her hand through her bangs. Before Hiei could answer, the demon rose up behind her. Not even blinking, she pulled a dagger from somewhere, pivoted on her heel, and threw it at the demon, hitting it dead in the throat and knocking it flat on it's back.
"Would you PLEASE stay the hell down for once?! God, I am so SICK of chasing you down! This ends now!" She ran towards the demon, then jumped and landed on the dagger, plunging it in up to it's hilt. The demon made a choking sound and died.

The girl made a face and pulled her dagger out.
"Yuck." She muttered, pulling out a rag and wiping it off. She re-sheathed the dagger and started walking away, throwing a dazzling smile over her shoulder at Hiei.
"Bye cutie." She mouthed, disappearing into the shadows, leaving Hiei with his jaw scrapping the ground, his breath coming fast and his heart doing a weird fluttering thing.

That girl was all Hiei could think about all night, even though he was kicking himself mentally while he DIDN'T get any sleep. He tossed and turned in his small cot, closing his eyes only to see the girl in front of him. Finally, he began training with his sword, pushing himself to be faster and faster until he collapsed in exhaustion and slept.
The next day, Hiei let Yukina convince him to 'hang out' with Kurama, Yusuke, Keiko and Botan. he didn't want to admit it, but he was actually having fun. And then he saw her. She was ordering a shake at the diner when they walked in, wearing a sky blue mini skirt and a white short shelve blouse, with knee high leather boots and a long black leather duster.

Now that Hiei had the chance to study her in daylight, he did so. Her skin was a pale ivory, contrasting sharply with her green hair and bright red eyes. Except for her eyes, which were huge, almond shaped and silted like a cats, her features were tiny. A pointed chin, snubbed nose, and heart shaped lips perfect for pouting.

She smiled when she received her shake, a smile nowhere near as dazzling as the one she had flashed Hiei, but still dazzling. She started towards the door, but Hiei wasn't letting her go this time. He followed her out of the diner, leaving Kurama, Yusuke, Keiko and Botan staring after him.
"Hey!" He yelled, rushing after her. She was fast! "Hey! Just a second!"

She glanced over her shoulder at him and stopped.
"Well hey cutie."
"The names Hiei." He said shortly.
"Nice to meet you Hiei." She said with a slight nod before continuing on her way.
"Hey!" He yelled after her. "I didn't get your name!" She glanced back over her shoulder.
"That's because I didn't give it."

She disappeared into the crowds, leaving Hiei dumbfounded. His head whirled, and he couldn't seem to move. Then he mentally shook himself. 'Come on Hiei! What's the matter with you? What kind of demon can't talk to a pretty girl?' With that decided, he followed the scent of rose oil, the scent he smelled on her. It wasn't easy, keeping track of one woman's perfume amid the smoke and exhaust fumes, but he followed a wisp of roses in the air down the block and around the corner before the wind shifted uncooperatively. 'DAMN!' He thought, momentarily losing her.

"What do you want?"
Hiei whirled around to find the mystery woman leaning against the chain link fence of a playground, her arms crossed atop her chest. She sounded and looked pissed. Hiei hesitated, almost losing his nerve until he mentally slapped himself.
"I just wanted to know your name." He said.

His explanation did not appease her. "I don't like being followed," she said coldly. "So don't." She turned to leave.
"Hey, wait. . . " He protested, reaching for her arm. To his amazement, she expertly caught his wrist in a flawless kempo lock.
"And I don't like being touched."

Strangely, her display of martial arts prowess only emboldened Hiei.
"Why don't you tell me what you do like," he challenged her, "and we'll start from there." He collapsed her hold and reversed their positions as she gasped in surprise, simultaneously deflecting his guard. Hiei suddenly found himself losing his position as she flipped away from him. The two began to slowly circle each other, testing the charged air between them, a dance both graceful and deadly: ballet meets kung fu.

"Are you sure you want to do this?" She asked.
"Are you sure you don't wanna tell me your name?" Hiei responded. She removed her coat and he took off his cloak, revealing the tight tee shirt he was wearing under it as they continued to size each other up. Suddenly, she launched a kick at Hiei's face, which he expertly parried. Then he swiped at her with his arm. She deftly slipped under the strike, then ran across the playground the teetor-totters. As Hiei approached, she jumped down hard on the end of one teetor-totter, causing the rising end to catch Hiei, knocking him backward toward another teetor-totter. Running to the second teetor-totter, she leapt onto the other end, knocking Hiei backward again. Quickly recovering, Hiei grabbed the uprising board and shoved down hard, launching her into the air and sending her flying into his arms.

"You're holding back." He accused
"Yes," she said tersely. Then she spun away from him, launching a pair of lightning chops and kicks. A perfectly executed spring punch targeted his head, and he evaded the blow with a little old-fashioned bobbing and weaving. The strikes came faster and more fiercely, requiring ever-greater effort to block and deflect.

An open handed strike came at his face, threatening to ram his nose into his skull. He grabbed her wrist with his hand and forced it away from his head, so that her high-velocity blow connected with nothing but empty air. She broke his grip within seconds and recovered by tossing a hostile kick at his head. Hiei side-slipped out of the way as the two preformed simultaneous back flips, both of them landing on either side of the teetor-totters, straddling them in perfect balance.

At the back of his mind, Hiei realized that he was endangering his demon identity sparring in public like this. If Koenma saw, it was quite possible that Hiei would be sent to prison in the spirit world, not a pleasant place, and one he would like to avoid. But he didn't care. Whoever this amazing girl was, she was worth the risk.
"All this just to get your name?" Hiei asked.
"Try asking for my number," she replied.

Hiei smirked to himself. Their fight had grown more intense, but also more playful. Unlike most of his brawls and fights, which were grim, dirty business, offering only the most brutal of pleasures, this bout was exhilarating, almost sexual in it's dynamic. They had anticipated each other's every move, connecting on a primal, instinctive level. Beneath his tee shirt, he was bathed in a healthy sweat. His heart and blood were singing. 'I wonder if she's half turned on as I am. . .'

He had no chance to wonder any longer. The woman used Hiei's own trick to turn the seesaw into a catapult, launching herself onto one board, causing Hiei to launch into a side flip and land on the same teeter-totter as she was on.
"Nice." Hiei smirked.
"Thanks."

The green-haired woman didn't wait for Hiei to regain his composure. Without missing a beat, she leapt at him, assaulting Hiei with a high powered lunge reverse punch. Hiei ducked beneath the lunge, then blocked the second blow. She countered with her forearm. The woman's scent and curvaceous contours were distracting him. He could feel her vibrant, passionate breaths, here the hot blood racing giddily through her veins.

A crescent kick knocked his sword from his side, sending it spinning across the playground, where it stuck into a park bench. A double-handed U-punch went after his head and stomach simultaneously and Hiei was forced to resort to an upper block, lower push combo to fend off both attacks. 'Talk about aggressive women!' he thought admiringly. 'She's really keeping me on my toes.'

Hiei knew the park bench was right behind him and retreated a few steps more. He let the woman think that he was about to back into the obstacle when, at the last minute, he pushed off the heavy iron bench and slid past her defenses, wrapping his arms tightly around her and trapping her own arms against her sides.

'Got you!' he thought euphorically. They were pressed together, cheek to cheek, and the scent of her washed over him. He could feel her lithe, well toned body, and hear her heart beating almost in synch with his.
"Stop hitting me," Hiei said. The woman smiled.
"Okay." Just for a moment, he surrendered to the seductive sensations, relaxing his grip. Big mistake.

The woman stomped hard on the bridge of his foot, then pushed him onto the bench. A roundhouse kick sizzled at Hiei's face, stopping inches from his nose.
"My name is Sahano Takani. I have to go." She began to walk away.
"Wait. . ." Hiei said, taking her arm and turning her around. "Don't hit me. I don't want any more trouble. Why do you have to go?"

Hiei honestly thought she was going to be angry at him. But instead, Sahano seemed a bit. . . sad.
"I have things to do."
"You mean like last night?"
"Maybe."
"Well, I guess I'll see you tonight than." Hiei said, amusement in his eyes and gruff voice. She laughed, the exotic sound making Hiei shiver.
"You going to come 'rescue' me again?" She asked with a smirk.
"If I'm not doing anything."
"Hmm, knight in shining amour. I like. Bye."

She turned to go, throwing him yet another dazzling smile over her shoulder. "By the way, I 'love' your hairdo." And then she was gone leaving him to retrieve his sword, and kick himself mentally. What the hell was wrong with him? He was acting like some idiot human! He was acting like he was in. . . love? Was that it? Had he fallen for that fast, smart, strong, agile, somewhat sadistic, sarcastic woman with a short temper and one hell of a fighting style who smelled like rose oil?

How had that happened? He was a demon, he didn't fall in love with humans! And yet. . . Yukina and Kurama seemed perfectly happy with Kuwabara and Botan. True, Botan wasn't truly human, she was a sprit guide, but close enough. Plus, Sahano was everything he had ever hoped to have in a mate. Strong and smart, with a smart mouth and an independent streak that said she wouldn't put up with any shit from anybody, not even him. So it 'was' possible. . .
Hiei was out prowling the streets that night when he was tackled from behind. He twisted as he fell, and landed on his back, Sahano on his chest, nose to nose with him.
"Tag. Your it." She leapt to her feet and ran, grinning over her shoulder at him. Hiei was stunned for a moment, then with his demonic smile in place he was on his feet and after her.

Hiei's demonic smile widened into a grin as he chased Sahano through the moonlit alleys and back streets of the city. Hiei knew them like the back of his hand and used it to his advantage. He drew closer and closer, finally diving and wrapping his arm around her, making sure he cradled her head as he slammed her into a brick wall, only hard enough to surprise her, not hurt or scare her.

Sahano stared up at him, eyes wide and amusement dancing in her ruby red depths. Hiei leaned down, feeling himself being pulled in, and unable to resist. He stopped when they were nose to nose, their noses actually touching. Their lips were centimeters apart, and they could feel each others breath on their lips.

Sahano's heart was pounding and she was having trouble breathing. Hiei and she were literally nose to nose. His arms were still around her, holding her tight against his chest, yet he was also using his body weight to keep her pinned to the wall. Hiei's breath was warm on her cool lips, and she felt like she would drown in his dark red eyes.

"Tag. Your it." Hiei finally whispered, pulling back and letting her go slowly. They stood facing each other, eyes wide, breathing erratic. This time, it was Sahano who made the first move. She reached up and stroked his cheek. Her hand was slightly cold from the night air as her fingers traced his cheekbone, down his jaw line to his chin, and then his lips.

His skin was warm and smooth under her fingertips. As her fingers traced his lips, his eyes slid almost closed, and he kissed her fingertips softly. Sahano jumped in surprise, and her finger left his lips briefly. But she quickly put her fingers back. Hiei's hand came up to cup her cheek, then he began to trace the contours of her face with his fingertips, copying what she had done only moments before, and when he reached her lips, she mimicked what he had done, kissing his fingertips.

She moved her hand over his face, and he mirrored her actions, both of them trying to memorize the shape and feel of the others face. Sahano's hand slid down to the side of Hiei's neck and he followed the motion with his own hand. His other hand came up and his fingers laced behind her neck. Sahano followed his move, her thumb stroking the smooth skin behind his ears, making shivers run down Hiei's spine.

He moved closer and she moved to meet him. At first it was just a light touch, just the barest brushing of lips. Hiei pulled back and stared at her. Sahano reached for him and pulled him to her, kissing him deeply. Hiei cupped the back of her head and deepened the kiss, his other arm wrapping tightly around her waist.

Sahano's hands tangled in Hiei's gravity defying hair as they kissed. She finally pulled back to breath and smiled up at him. Hiei opened his mouth to say something, but a gruff, course voice cut him off.
"The demon thief Hiei!" It bellowed. Hiei grimaced when he heard that and whirled around, trying not to let Sahano's gasp break his heart and failing miserably.

A huge demon stood behind them, baring his huge teeth menacingly. "It is time for me to extract my revenge!"
