A/N: Kay, SOOOO, I do not own any YYH characters, just the one that I created in my head :) The titles are actually based off of My Darkest Days' new album, I really like it *ahem* so here we go. I know it may seem confusing at first, but if you guys don't know, I kind of build everything up in a story. So here we go…

"What was so important baby breath that I had to ditch Keiko? Do you know-" Yusuke Urameshi walked into the office of Prince Koenma of the Spirit World. The office was as disorganized as usual, stacks of paper on the desk, books strew across the floor; nothing seemed to be in its place. The monitor on the side hovered over the room, screen black and empty. Yusuke's black hair was slicked back as usual, eyes ablaze in irritation, however, the moment he saw the look on the baby ruler's face, his chocolate colored eyes lost their aggravation and were replaced with a look of utmost seriousness. "Alright toddler, what the hell is going on?"

"Jesus Urameshi!" yelled a large, somewhat dumb sounding voice. "Took you long enough!" A large orange haired boy, dressed in a blue school uniform stepped out from the side. Kazuma Kuwabara stood towering over the team leader, his orange hair standing out against his small black eyes and pale skin. Kazuma's height had no intimidation factor on Yusuke; in fact, it hadn't stopped him from giving the orange haired man a piece of his mind.

"Well I had something to do, okay!" yelled back the black haired boy, a fire igniting in his brown eyes.

Koenma sat in his oversized chair staring at the two boys going head to head with one another. He knew he did not have much time and this spectacle of foolishness was making him weary with irritation. By this point, his irritation increased and a vein was slowly protruding from his head as the half-demon managed to get the orange haired boy in a chokehold.

"Now what did you say Kuwabara?" he laughed, tightening his hold even more.

"Kurama…" Koenma looked at the red-haired kitsune leaning against the wall, eyes pleading to break up the two boys. Giving a curt nod, Kurama stood up and uncrossed his arms, clearing his throat in the process, attempting to gain the other two's attention. His emerald eyes noted the look of desperation on Koenma's face. 'This cannot be good' He thought.

The two boys finally relaxed and straightened up facing the Prince in front of them. Yusuke turned his head and faced the red haired fox demon at his side.

"Good to see you Kurama."

"If only it were under better circumstances…"Muttered the emerald eyed demon, mind wandering anywhere but to their current, tense predicament.

Their team leader gave a small nod and shifted his gaze next to Kurama. "Hey Hiei, did you get shorter?" Snickers erupted from the previously silenced Kuwabara.

The small demon next to Kurama stepped out of the shadows, crimson eyes glowing, face stoic, and clad in black. "Don't push yourself detective," he growled while sending a menacing look at the orange haired human he claimed to despise.

"You're as chipper as the last time I saw you," muttered Yusuke only receiving a 'Hn' in response. It has been a while since Koenma called in the entire team in such urgency; the idea not only thrilled Yusuke, but scared him at the possible threat that might be occurring. The look on Koenma's face seemed foreign to the team at this point; such urgency hasn't been present since the Demon Tournament.

"Koenma…" Kurama stepped forward, face filled with curiosity and dread. His green eyes assessed the ruler sitting in front of him. What was an illusion of a baby was easily shattered when he finally spoke up.

"We have an issue," He spoke, earning a scoff from the three eyed demon in the corner. "…and I know you won't be too happy with the information I'm about to tell you…"

The night was silent. Clouds covered the moon and stars, casting a shadow over the already silent city. The sidewalks were still wet from the night's previous rain; puddles mirrored the only light illuminating the streets. For a city that was usually bustling, tonight it stood still and silent, like a placid lake. A calmness that should bring serenity only gave off a foreboding sense of danger.

"Do I have to do everything myself?" muttered a dark shadow as it stalked the streets; silent as the night. The cloaked figure practically glided on the sidewalks, reaching its destination, a tall complex reading the bright red words 'Mega Corp.'. Silently, the figure leaned over the corner and assessed the situation at hand. 'Maximum security' he thought. He leaned over a bit more and closed his menacing wolf-like eyes, a few moments a breath was released 'Approximately twenty to thirty guards.' A hand reached over to the hilt of his katana. 'Big man's all the way on top' Taking one last breath, the figure turned the corner and disappeared into the shadows.

"Hey man," grumbled a low level demon guarding the building's glass doors. 'Pitiful' the figured scoffed. 'Demons working for humans…what has the world come to?' He stayed silent, listening to the conversation at hand. "You know, I heard some rumors going around that the Silent Assassin returned."

The second one next to him, looking practically identical in appearance, small beady eyes, blue skin, and a face only a mother could love, began to shake in laughter. "Don't be an idiot; the guy's been dead for decades."

"Dead?" the other exclaimed, rubbing his neck in slight nervousness. "I dunno, I've heard otherwise…"

The second rolled his eyes. "Dead or alive; sounds like the guy just has an ego, if you ask me. We could take him. Besides, with what we're doing, he would want nothing with Yatsuki." 'This is tiresome' the dark figure grew bored of the two and began to silently move.

A thud was heard as a demon's body dropped to the floor, head rolling off to the side. Before even registering the situation, the second was decapitated in mere moments as a sharp silver blade connected with his throat. One swipe and down. The figure gave no look to the two slumped bodies as he disappeared into the shadows, cloak billowing behind him. The kill was unnecessary, but his point was made as he slid through the doors, his small, dark frame undetected by every form of surveillance.

"Ruki," a voice echoed through the earpiece in the shadowy figure's ear. "Was it really detrimental killing those two?" The voice was deep, dark, and reeked of authority. The small figure stopped walking and leaned in a dark corner, slightly crouching. A voice that seemed to have power over many had no effect on him.

"Do not question me Saito," He hissed in response, growing slightly irate with every moment. The building was under full surveillance, demon, human, as well as machine. If he was to stick to his no casualty code, 'Ruki' needed to be alert. "You paid me, if I recall correctly." A 'yes' was given in response on the other side of the head piece. "Then don't tell me how to do my job." With that said he took off the headpiece and dropped it on the floor, destroying it with his foot. He then continued to phase through the shadows, silent and on a hunt. Ruthless, merciless, and a constant enigma. Those were words used to describe the Silent Assassin, a name that struck fear in the Demon as well as the Spirit World. Legends spoke of the death of the Silent Assassin and the fear he evoked during his living years. 'I'm back…'

X.X.X.X.X.X.X.X.X

A mop of shoulder length black hair stood outside the door of Spirit World's prince.

"Yes, come in." Koenma's baby voice called in from the inside. A short girl of small stature came in to the room, receiving a look of acknowledgment from the toddler at the desk. "Oh, hello Rei" he said warmly, smiling as if thoughts of dread were not plaguing his mind at all. The girl bowed her head respectfully, hair falling forward with the gesture. She recomposed herself and looked at the ruler. She was pale in the face with no trace of any color grazing her features, the girl was plain. Small nose, pouty lips, with almost no distinguishing features, aside from her eyes. Honey colored, pale eyes stood out against the black hair on her head. Bangs covered the right side of her face almost entirely; black hair hid a long vertical scar going down from the bottom of her eyebrow to the top of her cheekbones. The faded pink of the scar marred the porcelain that was her skin. Koenma never questioned the scar of the innocent and feeble looking girl in front of him, his sympathy for the creature standing awkwardly parallel to his desk made him give her the job of working for him. She did no work that an ogre couldn't do, but he could not resist.

"Umm, Koenma-sama," a low, detached, yet feminine voice squeaked from the female standing.

"Hold that thought," The toddler raised a finger and continued with the papers stacked on his desk. "Rei, could you be a doll and give Yusuke and the team a call when we are finished? Botan never informed me if she had contacted them or not…"Koenma's voiced trailed off for a moment. Rei began to grow bored; she slowly started picking at the thread protruding from her shirt. "Right, just tell them they need to be in my office," He looked at the time and calculated slowly. "In twenty minutes!" the toddler finally deduced before the stamping commenced. Rei gave a curt nod in response, not that he was even looking. The Spirit World Prince did not even raise his head, but instead continued muttering a string of profanities under his breath. The thought of a baby cursing brought Rei great amusement, but she kept her composure and realized she needed to get to the point of this meeting, quick, but the expressions of Koenma's troubled face evoked a slight curiosity, but moreover, a sense of pride.

"Everything okay, Koenma sir?" the girl asked meekly, using all her force to pretend like the issue concerned her. Yes, it was definitely pride.

Another sigh was emitted from the other side of the desk. The girl arched a hidden eyebrow and watched the ruler squirm in his seat.

"I suppose I could tell you…three years of working for me, this would not be much of a shock for you." A silence washed over the room. "Have you heard of the Silent Assassin?" For the first time Koenma made eye contact with the girl standing in front of him. Feeling uncomfortable under his gaze, Rei looked down to the floor.

"Why of course!" She feigned surprise, which was apparently good enough for Koenma to believe. "Everybody in the Spirit and Demon World has heard of him sir," She continued meeting his gaze slightly. "But sir, hasn't he been dead for more than a decade already?"

Koenma shook his head, a mix of emotions slitting across his face. "That is what we thought as well," He made sure not to disclose all the information and continued. "But as of lately, a string of deaths arose in the human world with the same M.O as the Silent Assassin."

Rei tried to detain the smirk that was threatening to appear on her face, she quickly covered it up with disbelief. "But Koenma-sama, are you sure it is him, and not some copycat demon?"

Koenma shook his head and shrugged his shoulders, "Just a feeling Rei, a feeling I pray is dreadfully wrong…" He regained his composure in a matter of moments and looked up at the seemingly innocent girl in front of him. "In any case, I am sorry to burden you with such news, but what is it you wanted to talk to me about?"

Rei nodded her head 'Finally, I can get to the point' "Oh, I feel this isn't going to lighten your mood sir, but I needed to inform you: today is my last day…" She gave him a sad smile, or at least she hoped it looked like one.

"Last day?" he exclaimed, "This is very short notice Rei…"

The small female bowed her head in what resembled shame, "I understand sir, but something came up that I need to take care of…"

Koenma let of a breath of exasperation. "Nothing is going right this week…." He muttered. 'Do not worry little Prince,' she thought 'The issues will not be of concern to you after this…' "Nothing dreadful I hope…" He finally added, genuinely worried about the feeble girl in front of him.

"No, of course not sir."

He nodded his head, "Very well then, if you ever need a position, you will always have a place here Rei."

This time Rei felt a wave of respect flood her from the sincerity of the ruler's voice. She bowed her head quickly and stood straight. "Thank you…for everything." She turned to walk when the door opened revealing two boys and two demons. Her eyes first landed on a tall, dumb looking, orange haired human. 'Kazuma Kuwabara…' Then to a black haired half-demon, with chocolate eyes; his face radiated confidence as well as the rest of his body language. 'Yusuke Urameshi' Next to him was a short, spiky haired demon with a white starburst in the center of his hair. His crimson eyes were cold and emotionless. She stared at the bandana for a quick second, 'Hiei Jaganshi, wielder of the Jagan eye…' Lastly her eyes landed the emerald eyed kitsune. 'Youko…' Realizing she would draw attention to herself, Rei dropped her head and briskly walked out of the room. Stopping next to the door, she leaned against the wall and closed her eyes, listening to the conversation in the room she just exited.

"WHAT DO YOU MEAN YOU MISSED HIM!" yelled the infuriated voice of Koenma.

"Look baby breath," said the voice that Rei presumed belonged to Yusuke. "Your intel was off, the dude was dead."

There was an abrupt silence in the room before Koenma finally spoke. "We need to find him, do you four understand me?"

Rei smirked and kept walking out of the building, satisfaction radiating off of her. 'Good' She stepped outside and leaned against the wall, closing her eyes.
