(Disclaimer: I do not own any of the Yu Yu Hakasho characters. This is my first fanfiction. So please forgive me for any miss spelling or wrong things I do for this story. And this story is based on when they first met the old spirit detective.)

Chapter 1

WHAT IS IT!!!

"Damn it," Yusuke yelled as he slammed his fist on the table, "how in the hell are we going to beat this guy!"

"Calm down Yusuke," Koenma said as he took a sip of tea. (He does not have that pacifier in his mouth at all).

"I think we need to tell him Koenma sir." Botan said as she got up from the chair.

"I think your right Botan." Koenma said. He gently set down the cup of tea. He got up and went to the window and sat on the window seal.

"What?" Yusuke said, "What haven't you guys told me."

You could tell he was starting to get upset. He did not like being left out.

"Yusuke, if you calm down we'll tell you." Botan said. The only other people in there where Hiei and Kurama. They were both at a chair in yusuke's living room (I know this is not the way in the real show I'm just making it up as I go).

"What is this all about?" Hiei asked. He did not know what Koenma was up to, but he knew it was nothing good. Hiei and Kurama looked at each other with a look in their eyes that pretty much said, "This is not good." They knew if it was something Koenma did not tell them it was bad.

"Well, what is it?" Yususke asked impatiently. If you could tell he is very frustrated and impatient. He had no idea what Koenma was going to say to him.

"Yusuke what I am about to tell you, all of you it must be kept under secrecy." He said looking very serious, "This is just between me, you, and the people in this room."

"So you can't tell your girlfriend or any of the girls except Botan!" Hiei said looking as he gave Yusuke the evil glare that he is nitrous for.

(We all know the look).

All right, all right. Yusuke said as he sat back in his seat. He would be patient, even if it killed him.

"OK, I will know tell you." Koenma said as he all so sat back getting ready to tell everyone.

Chapter 2

The secret they never knew

"Along time ago when my father was trying to find another sprit detective." Koenma said as he sat back you could tell he was having trouble telling this story.

"Well get on with it Koenma." Yusuke said as he tried not to yell it. He was still very impatient with koenma.

"I'm getting to that Yusuke," Koenma said as he set his tea down. He was contemplating on weather to lie or tell the truth. Botan made the decision for him.

"Its no use lying to them Master Koenma sir." Botan said with a sad look on her face. She know he was going to try and hid the truth. She knew he was trying not to hurt them but it was no use. It was either they found out by Koenma. Or get hurt finding out by someone evil.

"As we all know there are several different dimension and portals." Koenma said.

"There is one dimension were no one is allowed in to. It is a sacred place were there is another human world. It is said that there is humans and demons al like are kind to each other and get along with out fighting. It is also said that that is every ones double is." Koenma said sitting back.

"Wait! What are you talking about?" Yusuke said. He was confused he knew there were different dimensions. But he had never heard of this dimension.

"So what are you saying?" Kurama asked. He was a fox demon and he did not even know about this dimension. He was suspecting Hiei did though the way he was acting. Kurama knew he was about to find out.

"What he's saying is that we need to go there and
