Hey readers, this is AbhorsenSabriel87 again. I know you people are starting to hate my works, but this one is going to be almost AN Section free, and it'll be a little more dark than a few of my fics. Please be warned, the OC within this story is being borrowed from my friend Trenity170, but the story is pretty much her and me gabbing on the phone for hours on end.

Now, just so you all know, I don't own any songs by the band Carbon Leaf. I also don't own any Yu Yu Hakusho characters (duh) or else I would be a old, rich, Japanese guy writing these stories for profit and not a pretty, young, Irish American girl writing these fan fics for the fun of it with no reward other than your reviews. So please, review, but most importantly, enjoy.

Chapter 1: Enter Darkness
-----------------------------
"And I've been here since I was I boy, the sky unwrapped the world my toy... A movie reel a million miles long... on and on... Scene after scene passes by my life: the window's a wound, the road is a knife... The irony he asked me, "'Where have you been?'" I don't know, I don't know because I don't know where to begin." The song blared tragically in Yusuke's ears as he ran through the streets of his hometown, breathing hard. He had started running at night to increase his speed and stamina after an almost humiliating defeat via his long time teacher Genkai. Old as she was, the hag had a lot of strength and speed. It didn't really help that she was so much shorter than him either; it made her harder to hit. So, he decided to start training outside her temple in whatever ways he could... in this case, running across town from Kurama's house (where he studied with his thief friend) to his own.

"Too much to do, too much to see... Pictures to take, people to meet... When there's so much space in between... it overwhelms me... Scene after scene passes by my life: the window's a wound, the road is a knife... The irony he asked me, "'Where have you been?'" I don't know, I don't know because I don't know where to begin." As of late, he had acquired a taste for American music as he ran, this band being known as Carbon Leaf, from Washington State. He didn't really care about where they were from; he just liked the music, and it helped him improve his English, something he'd tried learn since their devastating mission in Chicago over a year ago... He shook his head to clear the thoughts and resumed listening to the mildly depressing song on his CD player, his long and well-toned legs moving swiftly down the empty road. Most of the lights had either been burned out for months or been painted out by vandals, but he didn't really notice; he knew these streets like the back of his hand, so to speak. At almost two in the morning, he was about to pass the streets that led from his best friend Kuwabara's house to his own.

"And I've been here since I was a boy... now a heart full of fear and a mask of painted joy... So much for these youthful eyes to see... so much for peace and tranquility... One prairie outpost you are how I feel... Alone in a flatland 'tween the dream and the real... The irony he asked me, "'Where have you been?'" I don't know, I don't know because I don't know where to begin." As his song ended and started switching to the next track, he slowed and turned off the music for a bit to enjoy the silence of the night. As far as he knew, silence was a bit of a blessing every once in a while in the city. He shouldn't spend it listening to music. That's when he heard it; voices from the alley two blocks down, in confrontation. Not being one to miss a fight, but also not one to senselessly intrude in another man's fight, he crept up quietly on the alley and looked around the corner with his back against the wall so not to be seen.

"Give it up," a young man said coldly to a shadow, his bokutai drawn and steady. He seemed only a few years older than Yusuke, twenty to twenty-five at best, and had an accent on the words he spoke, almost British but not quite. "I'm an Underworld Agent, and Lord Enma Jr. demands to have an audience with you." A harsh chuckle comes from the darkness of the building shading the unknown other from view, and a voice even darker replied, "What if I don't want to come? Will you actually kill her? An innocent? I thought you Reikai Tentai were profusely against such a thing."

"We have no intent of harming the girl," the other answered back, shifting into a more comfortable position for attack if necessary. "We only want you to talk to Lord Enma Jr. He swears no harm will come to your host if you give yourself up freely." What the Hell? Yusuke thought, trying to figure out the situation. What does the brat want with some creepy guy that he didn't send us out to get him? And who are they saying they won't harm? His "host"? Is the guy possessing her or something? What the Hell is going on?

"Heh," the shadow chuckled. "You're lying. That brat you call your boss is an idiot if he thinks that could possibly be the case. He already knows her soul is lost; if he takes me from her, she'll die. So why don't you just run on back and tell him that, okay little human?"

"I'm sorry, but I have strict orders to bring you back. Dead or alive, that's your choice." The shadow chuckled darkly again, a sinister laugh that chilled Yusuke's spine as much as one of Hiei's infamous glares. "Come at me then, if you dare," it taunted, the voice male and powerful. "I can assure your twig of a sword will have no effect on me."

"We shall see demon!" The Spirit Detective raised his sword and darted in for an attack, but before he reached the darkness, he stopped short and dropped his sword to the ground, silenced by something unknown to Yusuke. "What a pitiful being," the voice sighed, and all of a sudden a sword-shaped shaft of black pierced through the young man's back into the air behind him. The thrust had brought the attacker into the light of the moon, and the sight of him brought Yusuke's breath to a terrified stop. His eyes and hair were as black as the night itself, but didn't reflect the light at all, just sucked in light like black holes. His face showed nothing of compassion to the slain human, only disappointment and a smug air as he ripped the blade of shadows from the body of the still breathing young man and gazed on him with regret.

"A pity," he stated softly. "A few more years and you could have made a challenge to a mediocre fiend from my realm." Without hesitation, he slashed through the young Reikai Tentai's neck, spraying blood on the walls and himself as he decapitated the poor human. "Tell Koenma I refuse his offer unless I can see the one who betrayed me and can return home," he growled, stepping his tall and slender frame back into the darkness and disappearing from Yusuke's sixth sense. But at the moment, Yusuke couldn't bring himself to try and chase him; he could only stare in sickened horror at the body of his fellow Detective until his legs collapsed from beneath him. Slowly, he placed his back against the wall once more and closed his eyes, trying to force the images from his mind as he drew the pocket communicator from his pocket and flipped it open. Opening his brown eyes long enough to press the transmission button to call Koenma, he soon saw the face of the toddler-like godling.

"Yusuke, what are still doing awake?" the toddler on the screen questioned, apparently in the midst of a lot of paperwork. "It's almost three in the morning. You should be sleeping in case I have a mission for you. Don't you have school tomorrow, too?"

"School can wait," Yusuke whispered, still sickened by the sight of such merciless killing. "One of your other detectives is dead, I saw it."

"What? Yusuke, what-"

"Don't ask me to explain, just send Botan to pick me up. I'll tell you when I get there." Before the godling could reply, Yusuke shut the communicator and breathed heavily for a moment, closing his eyes and resting against the wall until his stomach betrayed him and made him empty his dinner onto the sidewalk.

"I swear that's how it was Koenma," Yusuke pleaded, fear etched in his voice for the first time since Koenma had met him almost two years ago. "The guy in the shadows just drew a sword of pure black out of nowhere and stabbed your detective through the chest, then decapitated him after adding insult to injury, so to speak." Hiei stood in front of Koenma's desk, leaning on it as he stared hard at the distraught teen. He had been there when Yusuke had called only a few moments ago and decided to remain when he heard the details of the attack. He now thought over his own knowledge of who had access to such a blade, one Yusuke claimed was made of pure darkness. As far as he knew, the only living person who could do that was himself, but even he couldn't control the blade for long and many times nearly lost an arm or his head trying to. "Really, you have to believe me," the teen mumbled, falling into a chair with a defeated 'fwhump' and bowing his head in the same fashion.

"I do, Yusuke," Koenma replied softly. "Actually, this has been happening for quite some time now." Yusuke's head snapped up and Hiei glanced over his shoulder at the toddler. "How many?" Hiei asked, cold and aloof as ever. Koenma sighed and replied darkly, "So far, I've lost exactly nine Spirit Detectives, three of my best teams besides you all. I didn't think it would come to asking you four, but it seems I may have to."

"I'm not going after that guy until I know what the Hell I'm dealing with!" Yusuke shouted, sounding on the brink of hysteria. "That guy sliced up the other one in front of me without mercy or warning! Who the heck are we dealing with here Koenma, 'cuz he sure ain't human!"

"No, he's not," Koenma replied, his voice melancholy as it always was when he had bad news. "I can't tell you the details until we can get Kurama and Kazuma here, but I think Hiei knows what we're dealing with as usual." Hiei locked eyes with the godling, his cold ruby ones contrasting with the soft and deep brown gaze of his parole officer. With the look on Koenma's face, Hiei knew his first assumption had been correct; they were not dealing with a living person this time, at least not entirely. In fact, they were dealing with someone who had been dead for nearly three thousand years...

Someone Hiei himself had killed... and betrayed.
