Disclaimer: Do I really have to keep doing this? Okay people, aside from Jeff and Toma-su, I don't own anything except my pride, dignity, and my Jin plushie!

A.N. Alright, just a little note before we get this ball rolling. This chapter's not going to have Jeff in it whatsoever, it's going to be just Yusuke and co. figuring out how to handle this new information that they got from him. Anywho, with that said, on with the story!

Chapter 7: Research

Yusuke marches towards his house, slightly leaned forward in the position he took when he was thinking and didn't care if anything got in his way. Kuwabara was walking in the same position a little behind him and Botan was walking quickly, trying to keep up. They reach Yusuke's house and all go in, locking the door and going into his room before saying anything. Yusuke turns to Botan and says "Alright Botan, I know you know something more than what you're letting on. Spill it, now." In that voice of his that says that you better just do as you're told.

Botan sighs, leaning against the wall and looking at the floor before saying "Well, it's probably nothing, but I remember a few weeks back when I was checking up on Hiei, you know he never goes to his check-ins, I found him in the woods and it looked like he was training with someone. As soon as they sensed me the other one disappeared, but I didn't mention it, figuring it was none of my business. When Kei mentioned his 'other guy' I remembered. The other figure I saw had the same hair color and the same hair style as him."

Kuwabara scowls "You think this guy could be a demon?"

Yusuke rolls his eyes "Well duh Sherlock, if he was training with Hiei of course he's a demon, and a pretty strong one at that. Botan, do you think Koenma would know anything about this guy?"

Botan shrugs "Like I said, I didn't mention it before, but if anyone does, he's our best bet. Though I hate to disturb him this late, he can get quite cranky right before bedtime. Maybe I could get Ogre to let us into the database."

Yusuke nods "Alright, let's get going then, the sooner we find out about this guy, the sooner we can find him and get him to stop harassing Kei. The guy's got enough on his plate, he doesn't need to know anymore than what he already does. I still can't believe Koenma hired him to sit right outside his office, and he calls me brazen." He says, slightly sarcastic.

With that they're off to the Spirit Realm. Luckily, Ogre had just been locking up and it only takes a little persuasion from the trio to be let in, even going so far as to escort them to the database, telling them to lock up when they were done.

Yusuke grumbles as he looks through yet another stack of files. "Damn Koenma, he can find plenty of time to stamp papers, why can't he stamp a paper so that all this stuff is put in a computer database?"

Kuwabara, grumpy from having to leaf through his own pile, irritably snaps "Shut up Urameshi. Less yappin' and more lookin' the quicker we get through this the better."

Botan remains quiet, breezing through her portion, apparently she'd had to do this kind of thing before several times, because for every one file Yusuke or Kuwabara got done, she did five. Suddenly she gasps, causing the others to look up from their work. "What?" Kuwabara asks, "You find him?"

Botan shakes her head "No, but I did find something, probably even better then his file. I was reading through this report on demon physiology and I found something that may explain a lot about everything. Why Hiei is so interested in Kei, what connection this 'Toma-su' fellow has with him, and who they are to each other." Intrigued, the others come over and read over Botan's shoulder.

Two sets of eyes dilate quickly as Yusuke mutters "No way." and Kuwabara just gulps.

They look at each other before nodding in silent agreement. They needed to find this Toma-su, and Hiei, quickly. If they didn't, Kei's life would be turned even more upside down then what it already was. They all get up and rush out, all trying to think of a way to find the elusive koorime and his training partner, leaving the files strewn across the room, and one particular file wide open.

(A.N. So you guys, you wanna know what was in that file that got them so worked up? Huh, huh, huh, do ya', do ya'? lol, sorry, I'm hopped up on caffeine lol. Alright here it is.)

Demon Energy Regulation: A natural and necessary process for some varieties of demons that occurs every 50 to 100 years, depending on the species. This process involves the expelling and concentration of a portion of said demon's energy. After a short time, this energy metamorphisizes into an actual life form. Usually unable to cope with the amount of energy inside it's body, the life form splits into two parts, one demon, one human. Why a human manifests itself from pure demon energy remains unknown, but nevertheless, it happens. After the separation, the original demon can choose to abandon the human counterpart, but usually leaves it to be claimed by other humans. However, if the bond that is held between the two halves is not recognized and accepted by the time eighteen years pass, then both will cease to exist as the bond is broken. Just how the bond is recognized and accepted is unknown to all except for those who go through with it, but most of the time it seems that the human counterpart becomes part of the demon, never to appear again.

A.N. Bum bum BUM! Uh oh, what'll the gang do! It seems like a no win situation at this point, but don't worry! I'm sure everything will turn out for the best in the end! I've already got an idea of what could happen, but I'm not telling 'cause that would ruin things! Well, next chappie things will be back to normal, well as normal as they get in the YYH world. Well, see you next time, R&R please!
