Dokkou: Okay, ppl, here i am with another story. only this one centers around yu yu hakusho AND Harry Potter! I know that this concept has been done before A LOT but i just couldn't stop the inspiration from popping out of my head. So, here's my newest story. Hopefull it will be more popular than my other one, which only got 11 reviews in the long months it's been up.

Hm...I'm pretty sure there will be a HieixOC later on as well. Kurama too, possibly. I dunno. The idea's still new. So with that ominous thought in mind, sit back and enjoy my story!

Kurama: Also she doesn't own Yu Yu Hakusho or Harry Potter.

Dokkou: Yeah that too. though I don't know why I bother saying that. everyone KNOWS I don't own Harry Potter OR Yu Yu Hakusho. . Sigh...not that that's a good thing...

The Messages and the Explanation

"What's the matter, Kuwabara? Tired already?"

"No way, Urameshi! You're going down!" Kuwabara panted, scrambling up.

"Then bring it on!" Yusuke grinned, readying himself.

He and Kuwabara were sparring at Genkai's temple to let off some of the steam that their everyday lives built up. Yukina, Keiko, Botan, and Genkai were watching the fight from the sidelines; Genkai occasionally snapping criticisms at them, Botan, Keiko, and Yukina cheering them on.

"Go Yusuke!" Keiko shouted.

"You can do it, Kazuma!" At the sound of Yukina's voice, Kuwabara puffed out his chest and said, "Urameshi, you might as well give up! With my love, Yukina cheering me on, there's no way I can lose! I'm invincible! I fear nothing!" At that moment, a large gray owl dove down and started attacking Kuwabara's head.

"Agh!! Get it off me!! Get it off me!!" he screamed. Yusuke laughed until another owl, light brown, swooped down and landed primly on his head. His eye twitched.

"Stupid bird," Yusuke growled, raising a hand to swat it off.

"Wait, Yusuke, there's something tied to its leg!" Keiko cried. Yusuke blinked and pulled the paper off the owl's leg. It gave a satisfied hoot and soared off.

"It's an envelope!" Yusuke said in surprise, reading the address.

Mr. Y. Urameshi

Training Grounds

Genkai's Temple, Japan

"What the…" the four girls came over and looked at the sealed envelope curiously.

The gray owl was still harassing Kuwabara.

"'Dear Mister Urameshi," Yusuke read out loud, ignoring his orange-haired friend, "We are pleased to inform you that you have been invited to Hogwarts School of Witchcraft and Wizardry. Please find enclosed a list of all necessary books and equipment. Term begins on September 1st. We await your owl by no later than July 31st. Yours Sincerely, Minerva McGonagall, deputy headmistress." He looked up at the girls in confusion.

"Hogwarts School of Witchcraft and Wizardry?" Keiko said, "Is this some kind of joke?"

"If it is," said Yusuke, inflating like an angry bullfrog, "there's only one person I can think of who would send this."

"Are you thinking of Koenma?" Botan asked him. "I suppose it's a possibility, but Koenma is awfully busy all the time…"

"Well he's pretty good at fitting time in his schedule to bug me. Kuwabara, we're going to Spirit World," growled Yusuke. Kuwabara ran into a tree and the gray owl sat smugly on his head.

"Take the square root of 144, multiply by ten and divide by pi, then add the mean to…"

Tap tap tap.

Kurama blinked and looked up from his math homework.

Tap tap tap. Kurama's head snapped around to the window.

A large and rather beautiful white owl illuminated by the sun was standing on the outside sill, tapping the glass with its tiny black beak. Kurama blinked again.

"Hello, where did you come from?" He crossed his room and opened the window. The owl glided in and settled on top of Kurama's math textbook. The redhead looked at it in confusion. Owls were rarely seen during the day, and for one to suddenly just fly into his room in broad daylight was just plain unnatural.

It was then he noticed the owl had something tied to its leg—a piece of paper, it looked like.

"Now what's this?" Kurama murmured, pulling the paper off the scaly leg. The owl gave an amiable hoot and soared back out the window into the blue sky.

Kurama stared at the parchment envelope in his hands. Who still uses parchment? It's so old-fashioned. He read the spidery green writing on the front:

Mr. S. Minamino

Second Floor

Third Room on the Left

Tokyo, Japan

"How did they know…?" Now becoming suspicious, he tore open the envelope (neatly of course) and took out another piece of parchment, which he scanned over quickly.

"Hogwarts School of Witchcraft and Wizardry? What on Earth?" He frowned and sat at his desk, math homework forgotten. "If this is a prank, it certainly is an elaborate one. Sending a letter by an owl..?" He thought for a moment, then got up out of his chair and hustled downstairs.

This doesn't seem like a prank. I think I should ask Koenma about this.

"Goodness, Dear, where's the fire?" His mother asked him from the sofa.

"Oh, it's nothing, Mother, I'm just going out for a short while." Kurama said, pulling on a green and brown jacket. "I'll be back soon, I promise."

"Wait, Shuichi, where are you going?" His mother cried.

"To a friend's house," Kurama half-lied, "I just remembered that I left one of my textbooks at his house." And he quickly walked out the door and closed it behind him before his mother could say another word. He hated lying to her, but sometimes it was necessary.

"Alright, Koenma, you've got some explaining to do."

A small figure clad in black with gravity-defying black hair leaped up into the branches of an enormous oak tree in a small forest. He settled on one of the largest limbs and sighed.

Hiei was almost dying of boredom. He was still on his stupid probation, meaning he couldn't go to Demon World and get some actual exercise with the indigenous demons. There was nothing to do in the Human World except meander around and sleep, and Hiei had wandered around the city and surrounding forests so many times, he could find his way around blindfolded by now. Though he had to admit, one better thing about the Human World than the Demon World was that fewer things were liable to attack you when you slept. That and he'd begun to like the trees here in the Human World. Very little of its foliage had spiky bark and poisonous leaves.

Hiei swung his leg nonchalantly in the air and felt his eyelids droop and his naturally tense body relax. He'd taken a few laps around the city, but that had still been very monotonous. All in all, it had been a very tedious day.

Just as he was about to drift off to sleep, his eyes snapped open at the sound of wing beats. His demon energy flared threateningly and then an ash-gray owl with black and white spots landed fearfully on the end of his branch. When he realized that it was just an ordinary bird, Hiei's energy died down.

"Beat it," he snarled. The owl hopped back nervously, but didn't take flight. In fact, a second later, it was tentatively shuffling toward him. Hiei watched it with a hint of admiration. Any other creature he snarled at would have fled as though all Hell was on their back. But this owl was obviously determined to get close to him. So, curious, Hiei allowed it to approach. When it was only a foot away, the owl emitted an uneasy hoot and stuck its leg out, to which an envelope was tied. Feeling a prickle of interest, Hiei reached out and pulled the parchment off the owl's leg. The owl immediately took off as fast as it could.

Hiei read the front of the envelope and his interest, now tinged with suspicion, grew.

Mr. H. Jaganshi

17th Branch Up

Oak Tree

Wirakuum Park

He ripped the envelope open and read it with a scowl.

"Hogwarts?" he snorted, "What kind of name is Hogwarts?" The envelope began to smoke in his hand. "I know you have something to do with this," he said softly, looking up at the sky. "Koenma."

The envelope burst into flame.

Koenma sat distractedly at his desk stamping papers which he didn't even bother reading.

Stamp stamp stamp.

"Any minute now," he murmured.

Stamp stamp stamp.

There was a resounding crash in the hall outside his office door.

"My, my," a voice said, "Could that be them?"

Stamp stamp stamp.

"My friend," Koenma sighed, looking round at the ancient man sitting in a chair next to him, "it couldn't be anyone else."

BOOM! The doors to the study flew open so hard they bounced off the walls.

"Goodness, what an entrance," the old man said in amusement.

"KOENMA!" Kuwabara marched up to Koenma, not even noticing the old man, and slammed his fists on the desk. "You've got some explaining to do! Look what your stupid owl did to me!" Koenma drew back and stared at the furious carrot-top.

Kuwabara's face and arms were covered in small bleeding cuts and bruises. His blue school uniform had tears and rips all over it. It's an improvement, if you ask me, Koenma thought dryly.

"Jeez, Kuwabara, why are you getting so worked up? I've done way worse to you and you didn't complain this much." Koenma looked past Kuwabara to see Yusuke stroll in, closely followed by Botan.

Said ferry girl giggled, "He's just upset because he got beaten up by a night-flying chicken!" They both burst into laughter.

"Shut up!" Kuwabara yelled, rounding on them, "That bird was possessed, I tell you! It was attacking me for no reason!"

"I'm sorry to say this, but you tempt many people to attack you for no reason. Perhaps it's you hair style…" a thoughtful, soft voice said. Everyone looked around to see a familiar teenager with long red hair walk into the room.

"Kurama?" Yusuke said in surprise, "What are you doing here?"

"I came for the same reason you did." He held up the parchment letter.

"Hey! You got one too!" Kuwabara yelled, holding up his own invitation.

"So that makes three," Yusuke said.

"Hn. Four, you baka." Everyone (except Kurama) jumped slightly at the deep voice that issued from the shadows of the doors. Hiei stepped into the light, hands jammed into his pockets and an annoyed scowl on his face.

"Hiei! So you're here too," Yusuke said, ignoring the baka comment.

"Yes." Hiei turned his head. "Who are you?" he said rudely to the old man.

"Whoa! When did he get here?" Kuwabara shouted, staring at the stranger. Botan and Kurama sighed and Yusuke said scathingly, "He's been here the whole time, stupid."

"Oh… HEY WAIT A SECOND! I'm not stupid!" Kuwabara roared, which promptly led to a small scuffle that ended with both him and Yusuke trying to strangle each other on the ground.

While they were fighting, Koenma stacked a pile of papers on his desk and motioned to Botan. She came over to his desk.

"I need you to take these papers to the third floor, second office on the left. They're very important documents that must be delivered to their selected addresses immediately," said Koenma importantly. Botan looked at the swaying stack then looked at Koenma and pursed her lips.

"You didn't even read any of these papers, did you, Sir?" She said in a flat voice. Koenma coughed a little and said, "That's beside the point. Just take the papers to the office." Botan shook her head in exasperation but didn't dare disobey a direct order. She carefully took the papers in her arms and swept out of the office. She stopped at the door for a second and one look could tell clearly that she would rather stay and find out what all the fuss was about, but she had a job to do. So with a disappointed sigh, she strode out the doors, which automatically closed behind her.

Kurama gazed at the old the old man with polite interest. He was wearing a long blue robe and hat, both decorated with silver stars. A pair of twinkling blue eyes full of polite amusement and kindness surveyed the world over half-moon spectacles. He was giving off a very unusual aura, one that would rival a B-class or even lower A-class demon. In other words, this man could rival him and Hiei, and maybe beat them in a fight. Interesting.

Koenma finally lost patience with the two human Tantei.

"Will you two stop rolling around on the floor like immature children?!" He yelled.

"You're one to talk, Toddler," said Yusuke, shoving Kuwabara's fist down his own throat.

"Yusuke, Kuwabara, could you please stop fighting? I thought we came here to find out what the letters were about," said Kurama patiently. Yusuke blinked.

"Oh yeah, I almost forgot." The spirit detective stood and pulled Kuwabara to his feet. "So Pacifier-Breath, what's the deal with those air-mail letters?"

"Perhaps I should let my companion explain that, as he is the one who sent the invitations." The young ruler motioned to the old man, who stood up and swept his penetrating blue eyes over Yusuke, Kuwabara, Kurama, and Hiei (who was leaning against the wall looking bored and irritable).

"My name is Albus Dumbledore," the man said, "I am the headmaster of Hogwarts School of Witchcraft and Wizardry."

"So that place really exists? People really learn magic there?" Kuwabara cut in.

"Only certain people can learn to use magic—more specifically, witches and wizards."

"Are you supposed to be a wizard?" Hiei grunted.

"Why yes I am." Dumbledore smiled. Hiei looked him up and down.

"Prove it."

"As you wish," said Dumbledore simply. He reached into the sleeve of his blue robe and pulled out a long wooden sick. He waved it around in the air and then flicked it hard. Immediately a vase filled with golden flowers appeared on Koenma's desk.

"Cool!" Kuwabara and Yusuke chorused with grins, while Kurama's eyebrows rose a little. Hiei pursed his lips but looked convinced.

"Anyway, I came to visit my dear old friend Koenma because I have been under a lot of stress lately. I told him of a very dire situation that has the Wizarding world in an uproar. It must have been fate that we came to the subject of you, the Spirit Detectives. Koenma told me about your exceptional abilities, and I at once realized that you four are just the people I need."

"What for?" asked Kuwabara.

"I need you to go under the guise of students at my school and protect one of my pupils named Harry Potter. You see, the dire situation is that an extremely powerful and terrible wizard has returned to power, and is now targeting Harry's life. Harry needs to be guarded in secret."

"Forget it," Hiei's cold voice rang out. "I'm not wasting my valuable time protecting some sniveling human." So saying, the short demon strode for the door.

"Please, hear me out," Dumbledore said calmly. As he reached for the doorknob, Hiei felt a sudden tug on the back of his cloak. He blinked in bewilderment and felt some sort of force pull him gently but firmly into the middle of the room and steer him next to Kurama. Yusuke and Kuwabara exchanged surprised looks. Hiei glared at the old wizard, but his gaze now held wariness and a hint of grudging respect.

"Thank you," said Dumbledore graciously. "Now back to what I was saying. I require you four to protect Harry and the school from the evil wizard, whose name is Voldemort. Unfortunately, many people fear his name as well as himself so he should be referred to as He-Who-Must-Not-Be-Named or You-Know-Who."

"Kinda wordy, ain't it?" said Yusuke, scratching his head, "can't we just call him Bob or Joe or something?"

"I am afraid that would not be wise," Dumbledore sighed. "The people of my world have become so fearful of Lord Voldemort, they don't dare to even speak his name aloud."

"If you don't mind me asking," Kurama said softly, "could you tell us more about this Harry Potter and Wizarding world you claim is real?"

"Certainly," Dumbledore smiled. He was beginning to like that calm, polite young man. It was hard to believe Koenma's story that Kurama harbored a three-hundred-year-old demon fox inside him.

Dumbledore gave them a brief explanation of wizard's secret existence and of Harry's past four years at Hogwarts. He also told them of Voldemort's uprising, the trouble he was causing, and how it was all being blindly ignored because the wizarding community was too afraid to admit he had returned. He told them the momentous things Harry had done each year, and about his experience in the graveyard only last year.

"Man, sounds like this kid had it almost as bad as me," Yusuke commented. By the end of Dumbledore's explanation, Hiei was the only one who still didn't look ready to jump on a train and be a hero.

"I'm sure the Detective, the Oaf, and Kurama can handle this by themselves. I'm busy, and besides, I don't mingle with humans, even magical ones," Hiei said stiffly. At this, Dumbledore stood up and everyone realized just how tall (and intimidating) he was. The old wizard wondered if the little demon was trying to be difficult on purpose.

"Hiei, would you really turn your back on a world that is falling apart?" Dumbledore's voice was soft, but everyone felt the tension in the room. "Would you really allow an evil man to destroy the lives of innocents by killing and torturing those who opposed him? Would you allow him to annihilate the Human World, Spirit World, and Demon World to get what he wants?"

Red eyes met blue. The temperature in the room seemed to rise ten degrees.

"Would you allow him to hurt someone you loved?" the question hung in the air like a poisonous miasma. And then, unbelievably, Hiei broke the gaze and looked at the floor.

"No." he whispered. Immediately, the temperature returned to normal, and Dumbledore smiled cheerfully.

"Excellent. Now that you all know what is at stake, there is little else I can say, at least that applies to this situation. For example I could rant on about the lovely vacation I had in Mozambique a few months ago but I do not think it would hold your attention." And with that, he sat back down in his chair.

"Good, we've talked enough. Let's go already!" said Yusuke eagerly. Koenma grinned.

"I'm glad you're so enthusiastic, because I was going to force you all onto this mission anyway," the tiny prince said. To Dumbledore he whispered, "I should have you give out pep speeches like that to my hockey team!"
