Just to let you know, I don't own Yu Yu Hakusho.

Ch.1

"What!" a boy yelled as he slammed his fists on the table.

"Now, now Yusuke let me explain" Koenma said as he slunk behind a stack of papers that already half covered him.

All four members of the Reiki Tantei were in Koenma's office, expecting to get directions for their next mission. What they got was a bunch of pictures of some human children.

"I think the fool has finally snapped," a short boy with black spiky hair said. He was a fire demon named Hiei.

"Now let's give him a chance," a red-head named Kurama interjected. "Perhaps we just misunderstood. What do you mean these humans are our mission?"

"Well I'm glad at least the fox has some brains," the young ruler said. Things in the small room had quieted down, but Koenma couldn't help but feel that one wrong word would bring them right back up again. "As I was saying, these humans ARE your mission. I'm sure you all know about the Black Market." There was a wince around the room as everyone remembered how Yukina was captured, not to mention the Dark Tournament. "Yes, well, we have been informed about human experiments in the Black Market. The test subjects, as you probably guessed, are these kids. The cruelest thing is that they're being tested right in their own homes, unaware of everything." There was a long pause.

"That doesn't make any sense! How can someone be a lab rat and not even know it?" a tall boy with orange hair asked. This of course was Kuwabara.

"Why would they know?" Koenma asked back. "This certain experiment is testing human wave lengths. In order to do that the humans can't know they're being tested." Everyone in the room just stared at him.

"Oh, I've heard of that. Science labs in the Makai World often run experiments on human wave lengths to figure out what makes them so powerful, and to try to harness them." This statement comes from Botan, a blue-haired spirit guide wearing a pink

Kimono.

"…What are Human wave lengths?" Yusuke asked, confused and entirely missing the point.

"Yusuke, can't you remember anything?" the ruler asked.

"Um, no" came the short reply.

"Huh, Yusuke, remember when I was trying to put you back in your body, but you only had a short amount of time to get some one to kiss you."

"Yes" he said, turning beet-red at the thought of that embarrassing event.

"That was because your wave lengths were on very different frequencies. Got it!"

"Yeah, yeah," apparently he got the message. There was a long silence until Kurama broke in.

"If you don't mind me asking, what are they doing to test these humans?"

"I was getting to that. There are eleven humans in the experiment-"

"Why eleven?" Yusuke interrupted.

"If you'll give me a minute I will explain everything," he continued. "There are eleven because originally there were ten but another one was added to put over seas."

"Wha-"

"I'm getting to it!" Koenma was tired of getting interrupted. "You see the experiment is testing the connection between similar waves. Ten children with extremely similar wave lengths were placed in different cities, states, and the extra eleventh one was placed over seas in Korea."

"What happened to them?" This came from Keiko; she had forced Yusuke to bring her along, even though she wouldn't be going with them on the mission.

"Surprisingly enough, they all ended up in the same city, most of them are in the same school, but they all know each other one way or another."

"Wow, really!" Both of the girls were wide eyed and interested, but the boys looked like they had seen it before, which they had.

"Do we even know what demons are conducting this experiment?" Yusuke asked.

"Actually we do, why?" Koenma innocently, or as innocently as Koenma gets, blinked a couple of times.

"Then why are we standing around! Let's just go over to that lab and kick the ass of every demon-"

"You can't do that." Koenma interrupted before Yusuke went any farther.

"What, why!" everyone, except Hiei and Kurama, all but shouted at him.

"Well, they haven't done anything illegal yet. They haven't harmed the humans so there is nothing that can be done until they do. I want you to watch the kids, if something does happen, than you can act."

"So we're babysitting." Hiei had remained silent for most of the conversation, but now he had to say something, this did not sit well with him.

"Well, in a way, yes." Koenma answered while trying to avoid the death glare that Hiei was giving him.

"Alright then." Yusuke broke the silence while stretching his arms over his head. "What city are we going to, and how much is this bus ride going to cost me?"

"Oh, you can't take the bus." Koenma was bent under his desk apparently looking for something.

"Why not?" There was a long pause.

"Because you're going to America." He popped back up with five plane tickets.

"What!" the whole room exploded, yet again, but before they could act any further, they were hustled out the door, with Koenma complaining about being busy with paperwork. As the six of them stood outside Koenma's office, there was awkward silence.

"America," Kurama breathed as he took a ticket from Yusuke. "Well, I'd have to say this is going to be interesting."

"That's putting it lightly" Hiei said, but no one except Kurama heard him.

"Wait a minute, America." You could almost hear the click as Yusuke's brain put two and two together. "We don't know any English!"

"Oh I'm sure Koenma has a way around that." Kurama offered.

"Aren't those Americans supposed to be really weird?" Kuwabara had finally gotten over his initial shock.

"Well," Kurama thought for a moment. "I've heard that they're a lot more…"

"Undignified," Hiei put in.

"I was going to say a lot looser," the fox corrected, as he raised an eyebrow at the little fire demon.

"I don't care what you say; this is going to be fun!" Botan always could find the bright side of everything. After a long pause, three boys all moaned in unison.

"How an I going to explain this to my parents!"
