Chapter One

A/N: This is my first ever crossover. I started it then thought about how Aya got his powers and realized it was a story I needed to write. It's called A Violent Rebirthing. Check it out if you're so inclined. It is not a prerequisite for reading this story. I wrote it to tell the story of how Aya got his psychic abilities. Also why he and Youji are together...did I mention this fic was part slash? Well it is. No sex bits in this one.

"Can someone explain to me again why we're in a big, creepy haunted mansion that has no usable blueprints and eats people?" Mai sighed. "I mean the last time wasn't bad enough." She rolled her eyes and huffed. "I mean, seriously.

"We are here because we have a job to do." Kazuya replied. "If you're scared then go home and study. The more knowledge you have, the less of a scared buffoon you'll be." She wrinkled her nose at his back, buffoon indeed. She might not be the smartest teenage girl in the world, but she wasn't as stupid as he seemed to think. It wasn't smarts that made you unafraid of houses like this. It was stupidity and he might think she was stupid, but she was at least smart enough to recognize a dangerous situation when she was in one and being in this house was definitely dangerous

If he didn't want to hear her complain then fine. Mai would shut up. She returned to her normal task of setting up the shelves for the video monitors. She understood that her boss was a little full of himself sometimes, but not why. Besides the fact that he had a right to be. He was intelligent, handsome, talented, and the CEO of a company he had created at the age of seventeen. "Stop day dreaming and get back to work." Mai threw a glare at him, big jerk, she thought unkindly then pushed him out of her thoughts to focus on the task at hand.

In a couple hours they had everything in their base set up. The video monitors were lined up on the shelves with a table in front of them with the monitoring equipment on it. This was where Lin sat to view the screens. Of which only about half were up and running. The cameras and microphones for the others still needed to be set up. Kazuya would probably order her to do that menial task.

They had only the most basic layout of the building. So he would have her set up the rooms they knew of first. John and Bou-san would be with her to take room measurements and temperature readings of every room as she set up. To her surprise, Kazuya actually came along. So did Lin. They said that they were making a map. Perhaps they were taking this place more seriously.

"Let's make sure to be back before nightfall." Kazuya stated grimly as they headed out the door. They were done in about three hours. It would have taken her twice as long if she was by herself. As they were walking back to base a noise made her turn. A black, human shaped form crossed the hall and disappeared into the shadows. She stood there frozen and praying that it hadn't seen her. She really didn't want to die. Especially because her boss liked to take her into houses that people tended in which to meet their demise. Normally she'd never have come in here. Especially knowing what she knew.

A hand on her shoulder startled her enough to scream and turn around. "Oh, Bou-san." She gasped in relief, throwing her arms around his middle as he laughed. After a moment she pulled away. "Did you see it?"

"See what?" He frowned.

"That man shaped thing. It went down that way." She turned to point and found a wall where there had just been a hallway. "I hate this house already." She groaned.

Ken swore as he raced through the rapidly changing corridors. He'd gotten separated from Aya and now he couldn't find Youji or Omi. As he rounded a corner he ran full tilt into a solid body, which knocked him on his ass. Hopefully it was one of his friends. One of which stood out in his now muddled mind. "Abys-" He sat up and found himself staring into the dark blue eyes of someone definitely not Aya. "Shit." He groaned, getting to his feet. His team were supposed to be the only people here, right?

"Ghosts aren't solid right?" A young girl with light brown hair asked. The guy he had run into shook his head; irritation evident on his face. "Which means that you aren't a ghost." She said to Ken. She was standing next to the teen he'd ran into. Behind them was a tall man with dirty blonde hair and another teen with blonde hair and blue eyes, who reminded him a lot of two of the men he was looking for. Two women, one young and one approximately in her thirties came around the corner at a run. They all looked vaguely familiar.

"Uh, no." Ken stared at the teen like she'd gone as crazy as the house. Sensing a presence behind him he spun to find a tall, strike that, a very tall man in a suit with black hair that hung over one eye. He took a step back. The man's eyes reminded him of the ones the man he was looking for owned, only not as deadly. "Why, are you guys looking for one?" He looked back at the girl who had helped the young man he'd run into off the ground.

"Who are you?" The blue eyed teen asked. "What are you doing here?"

"First question I can't answer." Ken replied with a grin. "As for the second, would you believe I'm lost?"

"No."

"Fair enough." Ken shrugged. "I got separated from my fr-" Suddenly the wall in front of him spun throwing a stunned Youji and Omi to the floor in front of him. "Never mind, I found em. Hey guys." Omi slowly got to his feet and looked around at all the people.

"So that's where all the cameras came from." He sighed. "I was wondering, since they weren't there when we walked through yesterday."

"You guys seen A- uh well our other friend?" Ken glanced sideways at the other group.

"You lost him again?!" Omi gasped, obviously worried.

"Its not my fault!" The brunette whined. "He keeps taking off when my back is turned. Its really rather annoying."

"He might have been eaten by the ghosts." The teen girl in front of them said quietly.

"Ghosts?!" Omi's eyes went wide.

"Stop that, we already knew there was at least one." Youji sighed. "I don't think playing innocent will work with this crowd."

"You would be correct." The teen Ken ran into said quietly his blue eyes eyeing each of them carefully. "You aren't ghost hunters so what are you people dong here?"

"We're investigating the disappearances." Omi replied with a small shrug. "A different group that belonged to our organization went missing a few weeks ago while they were investigating this place."

"Your organization?" The teen's eyebrow raised slightly.

"HPRS. Hayabusa Paranormal Research Society." Omi used their cover story. "I assume you're from SPR. We were told that you would more than likely be here." Ken slapped his forehead. Now he knew why they seemed so familiar. He had read they're dossiers. The teen he had run into was Kazuya Shibuya. The seventeen year old owner and CEO of Shibuya Psychic Research. The tall man was his assistant Lin Kyoujo and the girl next to him was his part time employee Mai Taniyama.

If he hadn't been so worried about Aya he would have figured it out sooner. The others weren't Kazuya's employees, but were close associates. The tall blonde was the monk, Houshou Takigawa. The red haired woman was the Miko, Ayako Matsuzaki and the teen standing next to her was Masako Hara, the famous teen TV psychic.

"Ah, yes. I was told that there another group had been hired, but where is your equipment?" Kazuya frowned.

"We aren't monitoring the activity here yet. Right now we're just trying to find the other group that was sent in." Omi responded.

"Well, we did misplace a redhead." Youji glared at Ken who glared back.

"He. Took. Off." Ken stressed each word. He hadn't lost Aya on purpose. "What part of that do you not understand?"

"The part where you didn't follow him." Youji shot back.

"Guys please. Standing around yelling at each other isn't going to find him." Omi got in between them holding up his hands.

"If anything happens to him I'm going to kill you Hidaka." Youji growled.

"We'll find your boyfriend Kudou, so don't get your pant-" The rest of his comment ended in a grunt as Youji's fist smashed into his jaw sending him to the floor yet again.

"Youji!" Omi cried, forgetting to use code names. Oh well, it wasn't like SPR was in the same business as them so protecting identities wasn't so important. Ken spat blood and glared up at the tall blonde.

"Do you have any idea what the thing here does to people Ken?" Youji hissed. "You would if you had actually read the brief Omi gave you instead of playing that damn video game."

"I read it Youji, I'm just more afraid of Fujimiya than I am of a house that eats people, and if the house has him its gonna learn fast just how fucking dangerous he is." Ken growled getting up. Youji stared at him then burst out laughing.

"My God, you're right. What the hell was I so worried about?" He shook his head. "Knowing him he'll come waltzing up any second telling us that the house is about to blow." At the sound of running footsteps they looked up, but no one was moving. The footsteps passed overhead then back through the walls and then there was the sound of children laughing. "What the-"

"Its starting. We should head back to our base. We'll find your friend later, if he's not dead already." Kazuya beckoned them to follow. The three assassins looked at each other then followed. They were in over their heads with this one and they knew it.

Aya stared at the bloody disembodied head floating in front of him with a frown. Was this supposed to scare him? He walked right through it with a sigh. He should never have allowed Kritiker to force him into being part of this stupid arrangement. So what if he was psychic or the host for that TDB thing? It wasn't by choice and he didn't need the extra attention, but no, the 'Powers That Be' wanted him to kill evil ghosts with his mind. Because there were so few criminals left in the world that they had to focus on ghosts now.

He rolled his eyes irritably as another apparition came at him. He saw scarier images in his dreams and what was so frightening about a transparent bloody corpse crawling across the floor towards him anyway? Maybe he was desensitized by what he did for a living. He just stepped over it and continued walking. When he found Youji he was going to kick the damn blonde's ass. It was his fault they were in this mess in the first place...well technically it was his own feelings that had gotten him into this mess, but it felt better to blame the blonde.

This particular mess was Kritiker's fault. They had sent an experimental team of psychics in to assess and deal with the situation. When they had failed to report in; Kritiker had called Aya. They had asked him and his team to both ascertain what had happened to the initial group sent in and to make sure the house was neutralized should there be paranormal activity.

He already knew that first team was dead. They hadn't had a lot of experience or training; plus a lot of psychics made the mistake of trying to sympathize with the spirit. Aya was not one of them. The redhead honestly didn't care if the spirit of Tom, Dick, or Harry got enough hugs as a child or if Mary was yearning for her dead lover. His job was to kill people. Plain and simple. It left little room for being emotional. The swordsman only cared about how one person felt and that person was Youji.
