"You're here too, Kurama?" Yusuke asked as he walked to Spirit World's front entrance with Kuwabara behind him.

Kurama turned to them and said, "I was summoned by Koenma as well. I'm not sure why."

"It's got to be something big if we're all here," Kuwabara replied.

The doors opened to Koenma's office. He sat in front of them behind his desk, stoic as usual. "Come in," he insisted, "I called all three of you here today because I need your help. Once every millenium a-"

Yusuke asked, "How long is that?"

"1,000 years," Kurama replied.

Koenma said, "Listen to me! Once every 1,000 years Spirit World slightly destabilizes."

Kuwabara asked, "What does that mean?"

"Souls are very fragil," he explained, "even here in Spirit World. If this destabilization happens to the point of no return, souls will start to disappear and sease to exist. It's imparitive we get it back on track."

Yusuke asked, "And how do we do that?"

Koenma shouted, "If you'd shut up and listen to me I'd tell you!"

Kurama said, "The Spirit Crystal, right? The one on top of Hendorei Mountain here in Spirit World."

"And what the hell is that?" Yusuke asked, looking at Kurama.

Koenma explained, "Hendorei Mountain only allows humans that don't have ill-intentions to enter. Anyone who has bad intentions or is a demon will be purified on the spot, it's quite a painful process. To be honest, you could probably use Hiei's jagan to help seek out it's exact location but he's a demon and he has bad intentions. He wouldn't be able to get within 1,000 yards of the barrier without feeling sick, let along make it to the mountain."

"So shorty can't come with us," Kuwabara replied, "so what? Wait, isn't Kurama a demon?" He looked at him.

"He has a human body," Koenma replied, "so he should be fine. To be honest, I'd rather a larger group go together-"

Yusuke said, "But all you have is us. I get it."

Koenma replied, "All you need is a small sliver of the crystal, nothing more. Bring it back here and I'll restore Spirit World to it's rightful balance."

"So, where is this mountain we're supposed to climb?" Yusuke asked.

"Anyone else feel that?" Yusuke asked as he walked along the trail in Spirit World.

"You better believe it!" Kuwabara replied, "The air, it's like everything nice and wonderful hugging us at once. It's amazing!"

Kurama looked around and said, "Yes, it is interesting."

Yusuke said, "Mind telling us more about this place? Koenma didn't tell us much."

"To be honest," Kurama replied, "I've never been in this part of Spirit World before, but I have heard of it in legends before. Judging by how pure the air is around here I would have been too ill to continue already as Yoko Kurama. This is actually one of the main reasons regular humans can't know about Spirit World."

Kuwabara asked, "What do you mean?"

"The Spirit Crystal is said to cure any illness," he explained, "and to allieviate any pains, to cure everything in it's true form. Humans with good intentions would come flocking to this place, it's why the air is so pure, so demons can't try to do the same thing. To try and cure death somehow." He looked around at the strange landscape of large rocks and small hills surrounding the path they walked on.

Yusuke said, "Trying to cure death, huh, that does sound like a bad idea once you actually stop to think about it." He stopped and looked up.

"Whoa," Kuwabara said, "Is that Hendorei Mountain?" He looked up at the tall, pointy rock face in front of them with another smaller mountain in front of it, a path leading up the sides of it.

Kurama replied, "It fits the description I've always been told. The barrier should be around her somewhere."

Kuwabara started walked again and said, "What barrier? I'd sense something like that if there was one-hey." He walked through something completely see-through.

"I don't feel any different," Yusuke said, "must be a crappy barrier."

Kurama stayed back and said, "No, this is what truely filters out demons."

"I thought Koenma said demons wouldn't be able to get near the barrier," Kuwabara said.

"If I were still a demon," Kurama replied, "standing right here would make me feel quite sick, but I'd still be able to move. Walking through the barrier would mean instant purification." He hesitantly walked through the barrier and felt a sharp pain move across his eyes for an instant before going away.

Yusuke asked, "You alright?"

"Fine," he answered, "for now anyway."
