Warning: This story came to me while reading a fanfic at 4:00 in the morning that had nothing to do with Yu Yu Hakusho.  If it seems stupid… It probably is. ^_^ Read on.

CHAPTER ONE

As a Result of Sugar and Demons

"This is insane," Hiei muttered. The Reikai Tantei, along with their new assistants, Shadow Jaganshi and Eclipse Shinomori (they got hired with the help of Shadow's great persuasive skills, a.k.a. metal baseball bat), were walking through a frozen forest of cacti.

"Yes Hiei. Insane would describe frozen cactuses quite well," Shadow said matter-of-factly. She wrapped her black trench coat tighter around herself. "Snow should be against the law."

"Where are we, anyway?" Eclipse asked. "I think it's like... Impossible for cactuses to be frozen, isn't it?"

"Not impossible. But it's unlikely for cacti to be anywhere that they could get frozen in the first place," Kurama said, walking past the two shivering girls to walk beside Hiei.

"Why am I out here again?" Shadow asked.

"Because you had to go and be an idiot and get Koenma to hire you on as tantei assistants," Yusuke snapped. "Why couldn't you just sit at home with your goldfish and weasels?"

"Because I said so."

"That made no sense," Yusuke replied.

"I know. I just ate a mini Snickers."

"You what?" Hiei said, spinning around.

"I ate chocolate. Fear me," Shadow said.

"We do. You bet your whatever we do," Yusuke said, speeding up to take the lead and get away from Shadow.

"And you know what's worse?" Shadow said, smiling widely.

"No, what?" Hiei said nervously.

"I have more."

"Oh, crap."

"Where are we again?" Eclipse asked.

"We are inside some guy's strange hallucination," Yusuke said.

"We're inside a holographic world, actually. None of this is real. It's all in this guy's head. We aren't really here," Kurama explained.

"Run that by me again?" Shadow said, staring.

"We are all lying in that little chamber with all those wires attached to our heads. Koenma had to send us into this guy's head to pull him out of a coma."

"Is that possible?" Hiei asked.

"Who knows."

"So... There's no fast way to get away from Shadow?"

"If none of this is real, then I didn't really eat chocolate, did I?" Shadow asked.

"No."

"But with you, thinking you ate chocolate is bad enough," Eclipse said dryly.

Shadow laughed evilly.

"So, since we're inside this guy's head, is that why there are frozen cactuses around?" Kuwabara asked.

"Yes, Kuwabara. You would be correct in assuming as much," Shadow said, nodding. "For once, you're right. But that's a first."

"Hey!" Kuwabara complained. "That's not nice!"

"Whoever said I'm nice?" Shadow asked.

"You're nice to Hiei."

"Because Hiei is my housing companion and if I do not treat him kindly, he will kick my butt right out onto the street," Shadow explained, sounding smart.

"No he wouldn't! He loves you too-- ITAI!" Kuwabara whined as Hiei delivered a kick to the side of his head.

"Would you drop the love thing?!" he snapped. "We aren't mates, and as far as I know, we're not becoming mates anytime soon."

"But you want to," Yusuke taunted. "Don't hurt me!"

Hiei's glare was painful enough. Yusuke felt like his head was on fire. Wait... His head was on fire.

"ITAI! BAKA! MY HAIR!" Yusuke dove headfirst into a deep snow drift. "Ahhh..."

"You deserved it," Hiei said, peering down into the hole Yusuke had made.

"Shut up, Hiei," Yusuke said, twisting and turning to get himself to sit up. The snow cracked like it was a big frozen sheet of ice. Wait... Ice is frozen, so of course it would be a frozen sheet of ice... Baka.

"It cracked," Shadow said, looking down at him.

"No, really?"

"Yeah. Really."

Yusuke stood up, and the ice cracked even more.

"It cracked again," Shadow said, pointing.

"I know! Idiot! I'm standing on it!" Yusuke whined. "Now, let's hope I can get off without--"

The ice cracked and collapsed and Yusuke fell. A second later, the crack widened and the entire group fell, screaming and cursing, into a large frozen cave.

"What the heck?" Hiei said, looking around.

"WEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!"

Hiei spun around to see Shadow spinning around and around and around on a patch of ice, completely out of control and finding it fun.

"YAY!"

"Shadow! Get over here!" Hiei ordered.

Shadow attempted to stop and fell on her butt. And kept spinning. Right over a frozen waterfall. And you know what she said as she fell?

"WEEEEEEEEEEEEEEEEEEEEEEE!!!"

There was a loud thud as she hit the ice at the bottom, followed by a woozy groan.

"Shadow?"

Kurama and Hiei stupidly ran out onto the ice, slid, and ended up over the waterfall on top of Shadow.

"A little help?" she mumbled.

"Hey guys! I think we're supposed to go this way!" came Eclipse's voice. "Guys? Um... Where are you?"

"We fell over a cliff!" Shadow shouted back up. "And it was great fun!"

"Shut up, Shadow," Hiei growled.

"I think we should concentrate on going back up," Kurama said.

"Or we could go this way," Shadow said, pointing at a single tunnel-like hallway kind of thing leading away. "Let's take a vote. All in favor of going down this tunnel-like hallway-looking thing, say 'I'!"

"I," Hiei and Kurama said in unison, being as they didn't want to try finding a way back up the ice fall. Eclipse peered over the edge of the icefall.

"I," she said, looking around for an easy way down.

"ECLIPSE, LOOK OUT! DON'T FALL!" Yusuke and Kuwabara screamed, having finally gotten themselves up out of the snow and not knowing she was looking down at Shadow and in complete control of her balance. They ran towards her, slipped on the ice, and all three tumbled over the edge.

"Good one, slick," Shadow said as Yusuke landed with a thud on top of Kuwabara in front of her.

"Where's Eclipse?"

"You're on top of her."

The two boys instantly jumped up. Eclipse was flattened onto the ice.

"Itai..." she groaned, sitting up.

"Let's go!" Shadow chirped, skipping away. Well, skipping the best she could without slipping and falling on the sheet of ice that provided the floor. It had obviously been a river at one point, but it was frozen now. Duh.

After a few minutes of cautious walking (and skipping), the group came to a sheer cliff face. The river had led into a lake, and this was the end of it.

"Well, this can't be good," Yusuke muttered. "How are we gonna get up?"

"Use the stairs!"

The group turned to see Shadow skipping up a set of stairs. They were no where near as steep as the cliff, and had obviously been carved out of the rock. The tantei followed Shadow up the stairs as she continued skipping happily (and hyperly) down the path of snow.

"Guys, look at this!" Shadow called from around a corner. "I think it might be kind of important!"

The group rounded the corner to find Shadow standing face-to-face with a huge demon. Well, not exactly face-to-face. More like face-to-knee. The creature reached down and picked her up, holding her at face level. Now it was face-to-face.

"Put her down!" Yusuke yelled. He aimed his spirit gun... and was promptly hit with an icicle club. He went flying and plowed into Kuwabara, and both of them hit the wall.

"Guys, this thing smells really bad," Shadow complained as the creature took a swing at Hiei. "Could you please hurry up?"

"You're not completely helpless, Shadow! Do something!" Hiei yelled. "You're half demon!"

"I am? Oh yeah!" Shadow said. "But I think the sugar might be kind of... interfering."

"IDIOT! BURN HIM!" Eclipse screamed. Shadow closed her eyes and scrunched up in a little ball, concentrating. The creature let out a howl of pain and dropped her about fifteen or twenty feet to the ice, where she landed and melted a crater around herself before she could lower her temperature.

"KILL IT!" Shadow screamed, jumping out of the puddle she had formed and waving her arms around insanely. "KILL! KILL! KILL, KILL, KILL!"

Hiei and Kurama both lunged at the creature at the same time, their weapons drawn, and it promptly caught them in an energy sphere. It brightened to a blinding white orb, and a second later, the creature howled in pain, and Hiei and Kurama dropped to the ice. The creature disintegrated. Shadow ran to Hiei.

"Hiei? Are you okay?" she asked. He groaned and pushed himself to his hands and knees.

"I'm..." he stopped, sitting up. "Different."

"You're different?! What?!"

Shadow's attention was drawn to Kurama. He was sitting a few feet away gasping and whimpering.

"Kurama?"

"What... What is this?" he said to himself. "It's... Youko is... gone?"

"Youko? What?" Shadow said, confused.

"WHAT THE HELL!" Hiei screamed suddenly.

"Hiei?"

"He's... Youko is in me now."

"WHAT?"

"It's true," Hiei said. "I don't know how, but it's true."

"Then why am I still... me?" Kurama asked. "I have memories and knowledge of Youko... But he's gone."

"I don't know."

"Isn't this just all in that guy's head?" Kuwabara asked suddenly. "None of this is real, right?"

"I don't know," Hiei repeated.

"It's real."

"Oh, what the fuck? Youko! Man, how the hell am I going to deal with my friend being inside my head?" Hiei complained.

"You'll be fine. It's not like I'm going to kill you, Hiei."

"Oh, this is too much. I don't need voices in my head!"

"Hiei, come on. We need to finish our mission," Yusuke said. "We'll sort this all out later."

"No! We need to sort this out now! I don't want this fox in my head!"

"Oh, come on Hiei. Yusuke's right. Besides, I'm gonna have fun knowing all your thoughts..." Youko's voice said mischievously in the back of Hiei's head.

"What?! Oh, that's it! I want him out! Now!"

Suddenly, the entire cavern disintegrated around them and they found themselves lying on little table-like beds with wires attached to their heads. Everyone but Hiei and Kurama woke up instantly. However, the two demons were still asleep and were being watched closely by teen Koenma and an ogre. There were several other ogres and demons around, in front of screens and monitors and such.

"What's up, Koenma?" Yusuke asked, pulling all the wires off his head and sitting up.

"Something happened with Hiei and Kurama. There was a bright flash, then both of their brainwave monitors went berserk," Koenma explained.

"Why are we back here, though?" Kuwabara asked.

"I pulled you out of the fantasy world when Hiei and Kurama flipped."

"Oh. Why aren't they awake, though?" Kuwabara asked.

"Their brainwaves are still way different. I can't wake them up when they're unstable," one of the ogres explained.

"Oh."

Suddenly, without any consent of anyone else, Hiei sat bolt upright with a gasp and sat there breathing hard. Kurama woke up slowly and lay there looking confused for a second before sitting up.

"Are you still there?" Hiei asked, looking up.

"Yes, Hiei. I must say, you have a rather interesting mind. So different from Shuichi..."

"I don't care about my mind! I just want you out of it!" he snapped, getting off the bed. Koenma stared at him.

"Hiei? What's going on?"

"Youko has migrated," Shadow said.

"Huh?"

"He migrated. You know what that means, don't you, Prince?" she said, crossing her arms.

"I know what it means, I just don't understand. Youko migrated...?"

"Into Hiei. Something in that demon's head... He obviously has the ability to mess with souls and the like," Kurama explained.

"Then... How are you the same?" Koenma asked.

"Good question."

"Oh! I think I just discovered all your thoughts on Shadow," Youko said, sounding like he'd just hit the jackpot.

"Stop it, fox! Just cuz you're in my head doesn't mean you have to go make yourself at home and read every thought and memory I've ever had!"

"I'm sorry. But with Shuichi, I already knew everything he thought. With you, I have to familiarize myself with--"

"Oh no you don't!"

"You pervert!"

"Huh?"

"You have been using your Jagan for naughty things, Hiei Jaganshi."

"You! Fox! Would you stop it?!"

"Hiei?" Shadow said, tapping him on the shoulder. He spun around and looked at her with insanity in his eyes.

"I don't want this stupid fox in my head!" he growled.

"It's not my fault!" Shadow said, holding her hands up in surrender.

"I didn't say it was! But he's gonna drive me insane! I don't need my friend's voice in the back of my head!"

"It's going to be scary not having Youko's voice in the back of my head. It's been there for my whole life, now it's gone," Kurama said. "No more perverted comments, no more perverted suggestions... No more comments on Shadow... No more willing me to kill and steal and..."

"'Comments on Shadow'?! Just what kind of comments does that perv make about me?" Shadow asked, putting her hands on her hips.

"You don't want to know."

"You know, Hiei, you really should take a vacation from Shadow. You're spending too much time with her."

"Shut UP, fox!" Hiei snapped.

"Make a move on Eclipse."

"What the heck? No way, you freak!"

"Then make a move on Shadow. You know you want to."

"You're enjoying this, aren't you! I spend a lot more time with Shadow than Kurama does... or Shuichi... or whatever you want to call him now! And you know it! And you're overjoyed by that, aren't you!"

"Heh heh heh."

"Shadow, if I ever do anything perverted to you, feel free to hit me, but it's not my fault," Hiei warned, holding his hands out to his sides in surrender.

"I wonder if..." Kurama mumbled to himself. He pulled a rose out of his hair. Everyone stared at him for a second. "Nope. Hiei, you try." He handed the flower to Hiei.

"Try what?"

"Try to make it a whip. Try to do anything with it," Kurama said. After staring at the flower for a second, Hiei shrugged. The flower glowed slightly, moved, and a second later it was a twisted mess around his hand and wrist.

"Um... That's not exactly what I had intended to happen," Hiei mumbled. "It's kind of cutting me a little bit..."

Thin streams of blood were running down Hiei's hand.

"Pull your energy out of it!" Kurama instructed. A second later, the rose transformed and fell to the ground as Hiei stared at his bloody hand.

"Nice."

"Congratulations, Hiei. You're the new possessor of my powers."

"Like I care!" Hiei complained. "I want you out of my head! Koenma, is there anything you could do to get this fox out of my head and back where he came from?!"

"I'll have to think about that for a while, but I don't know of anything right off the top of my head," Koenma said.

"Noo!"

"I suggest you go home and rest. I'll call you back up here when I need you... But if you really have Youko in your head, I think it might be better that you stay out of the action for a while. You too, Kurama... Shuichi... whatever," Koenma said. "Yusuke, Kuwabara... Stay here. I still need this demon. Shadow, Eclipse... take a hike."

"Yes sir!" Shadow said. She grabbed Hiei's wrist and ran towards the door with Kurama and Eclipse walking behind her.

"This is gonna be fun..."

"SHUT UP!"

************************

I know, the way it happened was bogus, but hey, you never know. It's kinda like my Separation Situation story. I just put something about a bright flash of light and voila, they're back together.

In case you couldn't tell, Youko's talking in the back of Hiei's head is in italics and italic quotes. Just so you can tell. ^_^ This story popped into my head while reading a Rurouni Kenshin fic... It was 4 in the morning. Cut me a break. ^_^

The big question: Should I continue this fic?
