This is the first time I've ever really written a crossover (besides my parody Yu Yu Hakusho/Hunter x Hunter family feud). I'm not sure if I didn't a good job or not (you can be the judge of that). I hope you enjoy reading it. It was fun to write that's for sure!

"What's that weird energy coming from?" Gon asked as he looked at the tops of some trees. A bright white light was shining from the top of them.

Kurapika replied, "I have no idea, but I have a bad feeling about it."

"We probably shouldn't go near it then," Leorio said.

Killua said to Gon, "Whoever gets to the center of it the fastest wins!"

"You're on! Go!" Gon shouted. They sprinted into the forest at super speed, heading toward the light that shimered off of the trees.

"Wait!" Kurapika shouted, "We don't know what that is. You shouldn't go anywhere near it!" He ran after them at a normal pace.

Leorio replied, "I hope nothing bad happens." He ran after all three of them.

Killua made it to where the bright shinning lights were first, just seconds before Gon. "I won!" he shouted, "What is this place?" He looked at the ground and saw a black hole in the middle of a clearing with white streams of light bursting out of it.

"I don't know if we should be here, Killua," Gon said nervously.

Kurapika finally caught up to them and asked, "What is that thing?"

"Whoa," Leorio said.

"Let's check it out," Killua said as he inched forward. As he got closer be came encase in white lights that beamed off of him. Gon followed with hesitation.

"Hey!" Gon said, "This feels amazing! Try it guys!" He extended his hand for Leorio to come forward.

Before he knew it all four of them were sucked in to and flew through what felt like time and space. They all tried to scream but no noise came out as they fell further and further. Eventually they saw another hole below all of them and crashed landed back to to the ground.

As Kurama crossed the border to human world a black hole opened above him. Bright white lights shot out of it as people shouted and fell out of it. The hole disappeared as all of them laid on the ground in pain.

"Well that hurt," Leorio said as he sat up.

"Where are we?" Kurapika asked, then looked over at Kurama.

Kurama asked, "Where did all of you come from?" He looked at the sky and then back down at all of them.

Gon stood up and said, "Ma'am, can we you tell us where we are right now?"

"I'm not a woman," Kurama replied, trying not to let that get to him, "I'm a man. You're on the outskirts of Tokyo."

"What's Tokyo?" Killua asked.

"You don't know?" Kurama asked. We speak the same language, he thought as he looked at the sky. "I think I understand what just happened."

Leorio demanded, "Well then can you explain it to us?! You're more cryptic than Kurapika here." He glared at the blond.

Kurama replied, "You fell through an interdemensional wormhole. I've heard that they appear sometimes but I've never seen someone come through one before. We'll have to talk to Koenma about this at once." Good thing I happened to be coming back from demon world, he thought.

"Who's Koenma?" Gon asked.

"He's the ruler of spirit world," he explained, "come with me."

"What's your name?" Gon asked, "Your hair makes you look kind of girly, sorry that I assumed earlier."

"Kurama," he answered, "and no worries. That's not the first time that's happened."

Leorio demanded, "And what's a spirit world?! I don't think we should trust this guy you guys."

"Who else is going to help us out here in the middle of the forest?" Kurapika asked, "We don't even know where we are. It's better to try to trust a stranger first and then learn your barrings through them rather than wander on your own for days."

Kurama walked through the doors to Koenma's office where he was talking to Botan. "Koenma," he said.

"Oh hi Kurama," Botan said cheerily, "who are all of these people?"

"Koenma," Kurama said, "these people all fell out of an interdemensional wormhole. They aren't supposed to be here at all."

Koenma looked up at all of them from his desk and said, "Yes, those wormholes have been happening more frequently recently, but that's still normal."

"That's Koenma?" Killua asked.

"But he's just a toddler," Gon said, "how do you run anything?"

Leorio asked, "So this is where all of the dead people come through? And who is this?" He looked at Botan up and down.

"Botan's my name," she replied, "pilot of the river stycks, also known as the grim reaper in some cultures."

Koenma said, "I might just be a toddler but I've been around for hundreds of years. I don't have time to deal with this Kurama! I need a spirit detective."

"You haven't gotten a new one yet?" he asked.

"No and with Yusuke being a mazuku I can't exactly ask for him to do it now can I?" Koenma asked.

Botan said, "How do they even get back to their demension; whoever they are."

"I'm Leorio!" he said, "and I had no idea the grim reaper was so beautiful."

"Leorio can you focus for one minute?" Kurapika asked, "I'm Kurapika."

"My name's Gon and this is Killua," he said.

Killua said, "Let me get this straight, we went to another demension through a wormhole and we have to get back to ours somehow? Why don't we just find another wormhole?"

Koenma explained, "It's not that simple. Wormholes appear and disappear in a blink of an eye, also, there are several different universes out there and falling into another one could just send you somewhere else instead."

"I'm sure Yusuke would help if you ask," Botan said.

Koenma said, "I suppose we could give it a shot. I have to spend some time researching to try and figure out how to send them back anyway. Kurama, can you fetch Yusuke in demon world?"

"Actually he just went to human world," he answered, "I'll go and explain the situation."

As he left, Koenma said to Botan, "Can you watch over these guys while I research, Botan?"

"Yes sir," she said, then looked back over at them.

Leorio asked, "Who's this Yusuke person?"

"What's a demon world?" Gon asked. Botan sighed.

"Hey Kurama!" Kuwabara shouted from the park bench he was sitting on with Yusuke, "What are you doing around here?"

"What's going on?" Yusuke asked.

Kurama explained, "Koenma has a situation and since he hasn't found a spirit detective yet to replace you he was hoping you would help."

"That depends," he said, annoyed, "what is it?"

"Interdemensional portals appear and disappear randomly on a regular basis," he explained, "most of the time it doesn't cause a problem but this time four humans fell through one and we're hoping you'll help send them back to their world."

Yusuke asked, "That's it?"

Kuwabara said, "Seriously after having to save the world a whole bunch of times I thought this would be a major issue. What do you say Urameshi? It'll be just like old times!"

"Well it doesn't sound too bad," he replied, "why the hell not. Let's go!" He jumped off the bench he was sitting on.
