A/N: This is not a yaoi fanfic whatever ideas you might have gotten from the summary. There will also be a lot of OOC for the Harry Potter characters and this takes place in Jame's time not Harry Potter's time. That is all and please enjoy the fanfic.

Disclaimer: Sadly I do not own any of the Harry Potter characters nor the Yu Yu Hakusho characters.

What's A Hog Warts?

Chapter 1: Letters

Hiei sat cozily in his tree watching the sun rise slowly in the east. A bird landed on top of the branch next to Hiei's, but he didn't pay any attention for lots of birds perch on trees. However…it started to peck him. "OUCH! Damn it, get off," shouted Hiei as he whacked the bird away.

The bird, or should I say owl, hooted indignantly and held its leg out to Hiei. "What?" and then Hiei noticed a letter dangling from its leg. He reached out and untied the letter and soon it flew off. Hiei turned the letter over in his hands and read the back of the envelope with annoyance. "The second oak tree?" muttered Hiei and he jumped off the tree he was sitting on.

He gazed at all the trees in the park and saw that his was indeed the second tree and Hiei didn't even knew it was an oak tree. "Stupid letter," he muttered and opened. "What's a Hog Warts?" he thought out loud. After scanning it he shrugged and tore it to pieces. "I'm not going to school." He jumped back into the tree and settled down once more.

Kurama slept peacefully snuggled under his bedcovers before he was rudely awaken by a tap on the door. He groaned and stood up after the tapping didn't stop. Shuffling towards the door he pulled it open, but no one was there. "Strange," muttered Kurama, but finally realized the tapping came from his window.

Outside a tawny owl sat, perched on Kurama's windowsill as it tapped the window again with its beak. Kurama opened the window and the owl flew in and landed on top of his desk holding out its leg. Unlike Hiei's owl this owl was much older and experienced then the younger and violent owl. "Hm," thought Kurama as he untied the letter.

The owl seeing that the letter had been successfully delivered flew out of the window. Kurama scanned the back briefly and frowned, whoever sent the letter was obviously a smart stalker. "How does this person know this," muttered Kurama as he cautiously opened the envelope. "…Hogwarts?" thought Kurama as he read the rest of the letter. And unlike Hiei he saw that there were two papers. "A cauldron………." Kurama contemplated this before throwing the letter in the trash.

The next day dawned bright and fair and Hiei once again watched the sun rise. He glanced around and saw that there were no more violent owls and weird Hog Warts. A hoot behind him almost made Hiei jump…almost. "Stupid bird!" shouted Hiei as he turned around to find another owl. It held out its leg, "I don't want your letter!"

Hiei jumped out of his tree and walked away intending to ignore the bird. The owl huffed and ruffled its feathers as it flew off after him. It pecked him once twice before Hiei twirled around and grabbed the bird. "Listen," he said as the owl squirmed uncomfortably, "I don't want your letters and tell whoever's sending them to fuck off!" A low growl came from deep within his throat and the owl's already large eyes widened further.

After he let go the owl sped off dropping its letter in the process. Hiei glared at the fallen piece of parchment and picked it up. He ripped it into tiny little pieces and threw them up into the air as the wind scattered the torn pieces.

Kurama yawned and stretched slightly before walking over to his desk to finish up the rest of his homework that was assigned for the weekend.

He was just about finish when a tap came from his window. Kurama turned around and saw a white owl this time pecking on its window impatiently. He stood up and sighed as he opened the window. It held out its leg and Kurama reluctantly took it. The owl puffed its chest up with pride and flew away. However Kurama just tossed it into the trash knowing very well it was the same letter.

Days later Hiei was fending off a horde of jet black owls all with a red evil glint in its eyes and Kurama…well he wasn't getting any sleep at all.

"ARGH!" screamed Hiei as the air filled with the beating and flapping of wings, hundreds upon hundreds of wings. "Fucking leave me alone!" He started to run, but soon the owl overtook him and soon Hiei was buried under hundreds of letters.

Kurama was nearly pulling his hair out as owl after owl zoomed through his open doorway and windows. "What's going on?" screamed Kurama as piles upon piles of letters started to accumulate on Kurama's bed and floor and desk.

Finally after Hiei and Kurama went to the same psychiatrist and found out what happened to each other they decided to obey the letters after telling Koenma about how they wanted to take off for a year which Koenma reluctantly…disagrees.

"Listen Koenma I'm going to listen to this letter or else it'll kill me…literally," said Kurama as he waved the piece of parchment in front of Koenma's face.

"I'm with the fox," agreed Hiei and Koenma sighed, "How about this? I'll call you two on the communicator open a portal and transport you to the place where the mission is going to be taking place?"

"But what if we miss school!" shouted Kurama getting frustrated and irritable from all the stress…and owls.

"I'll only call you during the nights!" said Koenma as he held up his hands in defense. Hiei glared angrily at the young toddler before finally agreeing. "Fine! Let's go, kitsune." Kurama gave one last sigh before following Hiei.

A/N: …I know it's my first crossover fanfic (Please don't kill me ToCOrNot 77). It's not very good either…but that's alright after reading Harry Potter and Yu Yu Hakusho I finally thought, hey let's make a HP/YYH fic. Now here it is! Well I know this chapter was very short, but I'm not very good at long chapters, but the next few will be longer. Hoped you enjoyed it! And I need at least three reviews to continue…you heard me three.
