Yes, it's yet another Harry Potter/Yu Yu Hakusho cross-over, but I swear this one is not like any of the others. First off, I always forget the disclaimer so I better just do it now, I own nothing. Not HP, not YYH, and certainly not Kurama and Hiei. I do own Luna and I will put a curse on your family if you steal her!

The story line is a little confusion, so let me clear some things up. As for the Harry Potter part, Harry defeated Voldemort, just like in the book, but he died in the process. So, let's review, Harry died a baby and Voldemort is slinking around without any one to stop him when he regains a body or whatever. Does that make sense?

Now, for the Yu Yu Hakusho bit. This takes place before everything! Before Yusuke died, before any of them met, before EVERYTHING! Kurama is eleven...and the rest of that will explain itself. But just remember that when Kurama meets Koenma and Hiei, he's meeting them for the first time. Now, does THAT make sense? I sure hope it does. Now...(those of you who have read my other fics, you know what's coming)...ON WITH THE FIC!!!

-------------------------------------------------------------------------------------------------------------

He was gone. Voldemort was gone. He had tried to kill a small boy, a baby, and it had killed him. There was rejoicing throughout the wizarding community, but there was also morning. In the process of killing the dark lord, the boy responsible had also died. Many times over the next few years, scores of wizards and witches would meet at the boy's grave on the anniversary of the dark lord's defeat to morn his death.

"Harry Potter," the tombstone read, "He died to save us all."

----Eleven years later: New York City, New York, USA

A young girl, eleven years old, sped down the street. It was summer, glorious summer. No school, no bullies at recess, just her and a lazy, warm afternoon. She had her roller blades on and was enjoying her sport of maneuvering through the busy streets. Her favorite part was when she came to a hill and would suddenly pick up speed, making it even harder to avoid collisions. She loved the thrill, the excitement, the sheer adrenaline rush.

She was short for her age, just under five feet. If she had been an animal, she would have been albino. Her skin was pale and never tanned, or even burned. Her hair was pure white without even a hint of any other colors in it. As white as white could be, something that often got her teased at school. Her eyes were her most unique feature. Bright violet orbs that seemed to always be sparkling. Her real name was Prudence Campbell, but she hated that name and made everyone call her Luna. There was a very good reason for this nick name, but she never told anyone.

"Luna!" a voice called. She turned, grabbing a parking meter to stop herself.

"What?!" she called at the figure standing at the opposite end of the street.

"Mom wants you home, NOW!" it called. Luna sighed and started back. She was not going to enjoy this. Going down the hills was fun, but going back up was another story.

-()-()-()

It was a good half an hour before Luna found herself at her house once more. She opened the door, removing her skates and setting them off to the side.

"I'm home!" she called.

"It's about time!" her aunt Molly called from the kitchen. Luna took a step forward, and just barely jumped out of the way in time to avoid being hit by her skates, which had flown into the open closet, the door slamming behind them.

"How many times have I told you!?!" Aunt Molly huffed, hands on her hips. She had appeared in the hallway, a wand clutched in one hand.

"Put my skates away, I know," Luna sighed, silently thanking God the flying skates hadn't decapitated her.

"Remember next time!" Aunt Molly said hotly as she turned back to the kitchen. Luna sighed and followed. She had lived with her aunt and three cousins since she was three. Her aunt came from a pure blooded wizarding family, but somehow her sister, Luna's mother, had been born a Muggle. She had married a Muggle and they had thought they had had a Muggle daughter. At least, until Luna accidentally made a group of random objects around the room levitate as entertainment when she was board on day. After her parents died in a subway accident, Luna had come to live here. Her past had a few other twists as well, but that was always as much as she ever told anyone that asked, maybe leaving out the part concerning wizard terms and magic if the asker happened to be a Muggle.

"You got an owl. The letter's on the table," Aunt Molly said over her shoulder as she turned back to the spaghetti she was preparing.

Luna picked up the envelope. It was made of parchment and there was a red wax seal on the back. It was addressed to "Miss. Prudence "Luna" Campbell. Out roller blading. 600 Main Street. New York City, New York, USA"

Luna's heart skipped a beat, it was her reply; her letter from Hogwarts saying if they would except her. Her hands trembled as she broke the seal on the back. Due to special circumstances, all the wizarding schools in America had rejected her, which was probably just as well considering that Hogwarts was possibly the best school in the world. They had been told that Dumbledore was a kind man and would accept them, despite her...condition. She prayed that was true. Slowly, she removed the sheets of parchment inside, unfolded them, and began to read to herself.

"HOGWARTS SCHOOL of WITCHCRAFT and WIZARDRY," was at the top of the letter. Nervously, she moved her eyes down to the rest of the print. "Headmaster: Albus Dumbledore. (Order of Merlin, First Class, Grand Sor., Chf. Warlock, Supreme Mugwump, International Confed. of Wizards)" Luna didn't know what a "Supreme Mugwump" was, but it sure sounded impressive. She held her breath as she continued reading.

"Dear Miss. Campbell,

We are pleased to inform you that you have been accepted to Hogwarts School of Witchcraft and Wizardry. Please find enclosed a list of all necessary books and equipment. Term begins on September 1. We await your owl by no later than July 31.

Yours sincerely,

Minerval McGonagall,

Deputy Headmistress."

Luna stared at the letter, reread it three more times, then let out a triumphant "Alright!" that caused spaghetti to adorn the walls.

-----Tokyo, Japan.

Kurama sat quietly reading a book under a tree in the backyard. He was totally absorbed in the text; completely oblivious to everything else around him. A leaf fell on his shoulder and he reached up absently to brush it away, until he realized it was much to big to be a leaf. Confused, he closed the book and looked at the letter that had fallen on him. The envelope was of parchment and there was a red seal on the back. The address read "Mr. Shuichi Minamino. Reading under a tree. 1732 Fourth Street. Tokyo, Japan."

Even more confused then before, Kurama broke the seal and retrieved the parchment inside. "HOGWARTS SCHOOL of WITCHCRAFT and WIZARDRY," the first line read. It was followed by "Headmaster: Albus Dumbledore. (Order of Merlin, First Class, Grand Sorc., Chf. Warlock, Supreme Mugwump, International Confed. of Wizards.)" Kurama continued reading, wondering what in the world a "Mugwump" was.

"Dear Mr. Minamino,

We are pleased to inform you that you have been accepted to Hogwarts School of Witchcraft and Wizardry. Please find enclosed a list of all necessary books and equipment. Term begins on September 1. We await your owl by on later than July 31.

Yours sincerely,

Minerval McGonagall,

Deputy Headmistress."

"What?" Kurama asked aloud, completely perplexed by this mysterious letter. Was it a hoax? No, who would go to such lengths for a simple prank? He sat there, reading and rereading the letter for several minutes before he was interrupted.

"Oh my," a voice made him look up. His mother was standing there. She had brought some lemonade out for her son, only to find him reading the very thing she had been checking the mail for everyday for the past few weeks. "So you are one then. I always knew you were."

"One what?" Kurama asked.

"A wizard," she said simply. Kurama's jaw dropped. She knew? How did she know? More importantly, why didn't she tell him?!

"Come on, " she said, extending a hand for him to take, "I think we should discuss this inside." Kurama took her hand and stood up, leaving his book forgotten in the grass. She lead him inside and sat down at the kitchen table. Kurama sat down across from her, more than ready for some answers.

"Shuichi," his mother began, but she stopped, not sure how to continue. "Your father," she said finally, "was a wizard. But...he was not of a pure blood family. His parents were regular people, not magical, and...well, those were bad times you see, and..." she trailed off not sure how to continue.

"What?" Kurama asked, he had been asking that a lot today.

"There was this one wizard, a very bad one. We don't say his name. He's known as You-Know-Who. He didn't like people like your father, people who weren't pure blood wizards. So..." she trailed off again, tears beginning to surface in her eyes.

"You-Know-Who killed him, didn't he?" Kurama said quietly.

Shiori almost laughed. "I guess I should have expected that, you always were smart. We had been living in England at the time, so your name was added to the Hogwarts list. But, after your fathers death, I couldn't stay. You-Know-Who's base of operations was in London, and I was afraid he might come back...after you. I don't have any magic in me, and so you would have been considered just as impure as you father. So, we left and moved here. You-Know-Who was overthrown shortly after, but there were to many memories of your father in England and I couldn't go back."

Kurama stared. This was definitely too good to be a hoax, but it was still to insane to believe. He, the infamous Yoko Kurama, had somehow inherited magic when he was reborn? It was so hard to believe. And what was all this about England? His mother had definitely been in Japan when he entered her womb, when did they move? So many questions buzzed around his head, it was making him dizzy.

"I suppose we'll have to go to Diagon Alley. It's a good thing your so good at English," Shiori said absently.

"What?" Kurama asked for what felt like the millionth time.

"Diagon Alley, it's the best place to get supplies for Hogwarts. It suppose we'll have to book a flight to England. And hurry too. It's already July 10th. If we don't get an owl in soon it will be too late," his mother continued, but Kurama was barely listening. There were so many other thoughts fighting for dominance in his head he couldn't concentrate on his mother's words at all.

-()-()-()

It was nearly two in the morning. Kurama sat at his desk, reading the supplies list for Hogwarts for the tenth time. He couldn't sleep, there was too much activity in his head.

"HOGWARTS SCHOOL of WITCHCRAFT and WIZARDRY," this paper was headed just like the last. He continued reading.

Kurama sighed and laid the paper on the desk. This was all to ridiculous to be true. He nearly screamed when a puff of smoke exploded in the middle of the room.

"Hello Kurama," the figure in the smoke said. Kurama, who had stooped to set the chair he had toppled over when he stood up back on its feet, looked up at the mention of his name. The smoke cleared to reveal a toddler in a blue uniform with a bright blue pacifier resting securely between his teeth.

"Who are you?" Kurama asked, wondering how this baby A) talked, B) floated, and C) knew his name.

"I am Koenma, ruler of the Spirit World," Koenma answered proudly.

"What do you want with me?" Kurama asked hesitantly, he hadn't done anything wrong, at least, not since his rebirth as Shuichi Minamino.

"To be honest, I need your help," Koenma said. His eyes strayed to the letter on the desk. "Oh, good. I see you've gotten your letter already then."

"Yes, I have. What does Spirit World have to do with that?" Kurama asked.

"Well, you see, everyone who receives a letter is meant to attend Hogwarts. Every now and then, a demon will get a letter as well. In these cases, it's usually necessary for us to assign them a...partner who also received a letter. You know, to make sure that the demon attends the school and does everything he's suppose to and, well, doesn't kill anyone," Koenma explained.

"And you want me to be some demon's chaperone, is that it?" Kurama asked, realizing what the minute ruler was driving at.

"Right!" Koenma confirmed with a smile. "You'll love him. His name's Hiei. He's a fire demon. He was trying to track down the infamous Yoko Kurama, so, naturally, I thought that would be the best place to start when looking for a partner. So, I tracked you down myself, and you can only imagine my joy at finding you had been accepted to the school as well and so would be a perfect partner for that hot-headed demon!"

"What if I refuse?" Kurama asked.

Koenma's face fell. "You can't! Please! It's too close to the reply deadline for me to find someone else, and they wont let him in if he doesn't have a partner by then!"

"Alright, alright," Kurama put up a hand to silence the toddler's rantings. "If it's that important then I suppose it couldn't hurt."

"Excellent!" Koenma cried. Before Kurama could say another word, the baby floated to him, placed a hand on his shoulder, and the two disappeared in a puff of smoke.

-()-()-()

When the smoke cleared, Kurama found himself in what must have been Koenma's office. A short demon with crimson eyes and spiky black hair, dressed all in black, stood off to the side, arms folded casually in front of him.

"You must be Hiei," Kurama said.

"Hn. And I suppose you are Kurama," Hiei responded. Kurama nodded and Hiei pushed himself off the wall, walking towards him. He circled Kurama once, looking him over, and stopped in front of him.

"Definitely not what I was expecting," he remarked as he folded his arms once more.

"What were you expecting?" Kurama asked.

Hiei shrugged. "I don't know, it's just disappointing, that's all. But I think that trick you pulled, taking refuge in the human world, is what disappoints me the most. I can tell just by looking at you that it's made you soft."

Kurama was too tired and he had too many other thoughts at the moment to put up with this kind or ridicule. He narrowed his eyes slightly at Hiei and said coolly "If that's all you have to say to me I think I'll go home."

"One more thing," Hiei said. Kurama, who had half turned to order Koenma to take him home, turned back to meet Hiei's blood red gaze.

"What?" Kurama asked, he had grown to hate that word.

"What's a Mugwump?"
