3:47 pm, Ops Booths, Police Plaza

"Julius! Julius, come quick!" Foaly yelled outside his precious Ops Booth.

Commander Julius Root came huffing down the corridor, "D'Arvit, Ponyboy! What is it?"

"There's a call for you in Conference Room B."

Root stared at him with a look of anger on the brink, "That's it? Why couldn't you just patch it through to my office like everything else?"

"This isn't like everything else."

"Does this have anything to do with those weird attacks?"

"Yes." Foaly reluctantly admitted. "And it has to do with the crisis up above."

The Commander raised a graying eyebrow, "Above ground, you mean?"

The centaur shook his head and jerked a hairy thumb up waaaay above his horsey head, "I mean, up above."

Commander Root's face showed a small amount of alarm, a fraction of what really felt. He turned and darted to the conference room with Foaly trailing him.

3:30 pm, Koenma's Office, Spirit World

A toddler which a baby blue pacifier in his mouth was sitting at a very formal desk that was obviously to big for him. Before him were five teenagers. There were four males and two girls. Two guys about the same age were leaning against a wall, another who looked younger than them was sitting on the window sill, and the girl was sitting very close to the last teen male.

The toddler looked at the female sternly, "Kiara, are you absolutely sure you the call is on its way?"

The girl in casual clothing made her way out of her boyfriend's grasp and stepped forward. "Yes, Koenma, sir. We should be transmitting live roughly 15 minutes from now." Kiara made her way back to the sofa.

"All right. Listen to me, all of you." The extremely young lord looked around the room to make sure he had their attention. "The reason I've interrupted your vacation--"

A boy with slick back hair against the wall scoffed, "Yeah, which wouldn't be the first time, Binky-Breath."

"How many times do I have to tell you not to call me that?!" Yusuke rolled his eyes while Koenma cleared his throat,

"As I was saying... I interrupted your vacation because something has been happening in the Makai and underground."

An unintelligent looking red headed guy in blue next to Yusuke said in an alarming tone, "You mean demons are escaping and attacking the underground mole mutants?!"

Kiara sighed and turned her head to answer plainly, "Kuwabara, there are no such thing as 'underground mole mutants'."

Koenma cleared his throat to get attention once more, "Actually, Kuwabara is very close." After the exclamations of shock he continued, "Yes, demons are escaping and attacking something but it's not 'mole mutants'."

The intelligent looking young man next to Kiara spoke up, "Then what are the escaped demons attacking?"

"Fairies."

Kuwabara and Yusuke burst out laughing. Yusuke tried to balance himself, "No, seriously, what are they attacking?"

"Yusuke, I am serious! All I can tell you is that the fairies are a very advanced and very well hidden civilization. They've kept their existence a secret since the Battle of Taillte until someone re-discovered them about 6 years ago."

Kiara then spoke, "Who? And do they know about--"

"That's the point of this next mission; it seems that the person who re-discovered them could be very vulnerable to whoever is orchestrating the attacks. We need to protect him at all costs. And to answer your question Kiara, no, he doesn't know about us or Spirit World.

"All of you -- that means you too, Hiei --" The boy at the window was clad in black a frown etched on his face. "--will be going down to Ireland to fetch him and whoever else is in danger."

"What do we need another dumb kid for?"

Kiara giggled, "Yeah, Yusuke, you and Kuwabara are enough for already."

They both glared and yelled, "Hey!"

"That's enough you two." Yusuke and Kuwabara scoffed while Kiara went for the look of innocence. "Now, the call should be here in a few minutes. A portal is waiting in the middle of the forest near the park. Kiara, you're in charge."

She grinned, "Most awesome."

"Awwwwwww!" Yusuke whined, "How come I'm not in charge?"

Koenma glared, "You know why."

"But it wasn't my fault! If that lady didn't scream--"

"Koenma, sir." Kurama asked hoping to change the subject, "How long do we have?"

"A week at most."

He nodded and Kiara took over. "But sir, we don't even know what he looks like."

"You don't need to. All you need to know is his name."

"Which is?" She inquired further.

"Artemis Fowl the Second." He let it sink in as they heard an urgent beeping and flashing coming from the TV behind him. "That's them. Now go!"

At Koenma's signal, Team Urameshi sped out of Koenma's office in Spirit World in their own ways. Yusuke was leading them to the portal and arguing with Kuwabara behind him at the same time. Kiara and Kurama were behind the bickering boys talking and Hiei was bringing up the rear thinking about how he going to kill the idiots if they didn't shut up.

Ah, a normal day in their usual lives.
