DISCLAIMER: I don't own anything in this story AT ALL, except for Kou, whom I'm not sure will even show up. That includes the characters of Yu Yu Hakusho and the characters of the Harry Potter series. I do, however, own the plot, and if I can't plagiarize off J.K. Rowling and Yoshiro Togashi, then no one can plagiarize off me, and that's final.

Characters: Hiei, Kurama, Yusuke, and Kuwabara, with guest appearances by Yukina, Harry Potter and friends, and also Lord Voldything.

Setting: Any time after the Dark Tournament, but before Sensui.

Warning: Implications of rape and other evil things.

"This is not the way I had envisioned the weekend going," Hiei grumbled, staring at the high brick wall in front of him.

Kurama shrugged with one shoulder and reached out to tap one of the bricks with his finger. "I know, but…"

"It has to be done. I know. You've reminded me twelve times," Hiei muttered. "And no one wants to get those guys as much as I do. But why do we have to live so far from Japan in order to do that?" He turned around and leaned against the wall, crossing his arms over his chest and looking miserable.

"Why, Hiei, I do believe you're missing home," Kurama teased him.

"The only thing I would ever miss is your house, fox," Hiei muttered darkly. "Nothing else in the Ningenkai is even worth commenting on."

Kurama smiled. "Whatever you say, love."

Hiei was saved from replying by Yusuke and Kuwabara, who chose that moment to come out to the little yard he and Kurama were standing in.

"Hey, guys," Yusuke said. "You really should try the beer in there. Great stuff."

Kuwabara looked around. "Hey, weren't we supposed to meet this guy at a big white building?"

Kurama nodded.

"Then…where's the building?"

"Koenma mentioned that it might seem strange, but we should look in the trash can, and tap the brick three up and two over above the trash can with whatever we fine there," Kurama said, taking the lid off the metal trash can, the only thing that decorated the abandoned yard.

"What kind of an order is that?" Hiei asked. "How are we going to break a solid wall with garbage?"

Kurama pulled a wooden stick out of the can and stared at it. "Well, this is the only thing in there."

Yusuke snorted. "Koenma's putting us on."

Looking just as skeptical, Kurama counted bricks and touched one with the stick.

Yusuke gave a yelp and jumped back, and Kuwabara, Kurama and Hiei stared. The wall was moving. A hole had formed where the brick Kurama had touched used to be, and it was growing rapidly. In a moment, the hole had turned into a huge archway.

All four of them stepped through it and looked around, both curious and bewildered.

They were standing on a cobblestone street that twisted and turned out of sight. The street was lined on either side with shops and crowded with hundreds of strangely-dressed people going about their business. None of them seemed to notice the four foreigners in their midst.

"What is this place?" Kuwabara asked, voicing the question for all of them.

"What are those people wearing?" Yusuke asked.

"We can ask those questions to whoever it is we're meeting," Kurama pointed out. "I think we're supposed to be going to that building." He gestured to the huge snow-white structure at the end of the street that towered over all the other little shops.

"Kurama, are you nervous?" Hiei asked quietly as he, Kurama, Kuwabara and Yusuke began working their way down the crowded street, stopping from time to time to drag Kuwabara and Yusuke past certain shops, reminding them that there would be time for investigation later.

"About what?" Kurama asked, a little too breezily.

"The possibility of meeting that bastard face-to-face again."

Kurama grimaced. "Actually, I've been trying not to think about it, to tell you the truth."

"And how has that worked out?"

"Fine."

He was obviously lying, but before Hiei could press the issue, the group reached the white building, and he forgot what he was going to say when he set eyes on the bizarre-looking creature waiting to open the door for them. He was short and thin and clever-looking, with abnormally long fingers that looked as if they could easily strangle anyone who walked by.

The…thing leered at them and swung the door open, bowing rather mockingly at them as they passed.

The inside of the place was even bigger than it looked on the outside. Doors lined the walls, and more of the creatures were moving in and out of them, accompanied by more oddly-dressed humans. Behind a long counter sat hundreds more of the things.

"What the hell have we walked into?" Hiei asked, shifting his hand subtly to his sword hilt.

"Why, Gringott's Wizarding Bank in Diagon Alley, of course!"

Hiei stifled an outcry and whirled around, gripping his blade tightly.

The speaker turned out to be a tall, slender, old man, wearing a long purple robe and buckled black boots. He had very long, very white hair and a longer white beard, and he wore gold-rimmed glassed. Though he spoke Japanese quite fluently, he looked to be English.

After staring at him for a moment, Hiei asked, "Does anyone here wear normal clothes?"

"Hiei!" Kurama scolded. "I'm sorry, sir. He is very blunt."

"It's quite all right," the man said, smiling. "He's Hiei Jaganshi, and your name, I believe, is Yoko Kurama. And your companions are Yusuke Urameshi and Kazuma Kuwabara, am I correct?"

"Right. Koenma contacted you, then?" Kurama asked.

+Flashback+

"His name is Lord Voldemort," Koenma said, shuffling the papers on his desk. "Apparently, he's very famous—and feared—in his world. According to my sources, he plans to…"

"Rule the world," Yusuke finished.

"How'd you know that?" Koenma asked in surprise.

"I didn't, but that's always the story."

"Hm. Okay. Well, anyway, Yusuke's right. This Voldemort character wants to rule all the worlds. And to do that, he'll need help, more than he'll get from his human supporters. So he's turned to…"

"The youkai," Hiei finished quietly.

"Exactly. Voldemort has been recruiting youkai for about three years now. He has convinced all of the D and C-class youkai, most of the B-class, and now he has turned to the A-class."

"And how many of them has he persuaded to join him?" Kuwabara asked.

"Most that we know of," Koenma said grimly. "He has promised them riches beyond their dreams, but also, if he wins, he can give them complete freedom. They could come to the Ningenkai without fear of capture. They know this, and so they have united with him."

"Damn…" Hiei said. "He's raising a demon army."

"There is some good news, though," Koenma said. "We do have some on our side. Mukuro is going to send troops to fight the youkai on Voldemort's side, when she finds out where they are. And your friend Kou is trying to beat Voldemort to the S-class, and recruit them to our side instead. So we might be able to take the advantage, but I need my Reikai Tentei now. You four are very possibly the best of the best in the Reikai, and I need your help."

"What do we have to do?" Kurama asked.

"According to my sources, Voldemort's first goal is to kill one certain boy. He is seventeen years old, your age, Yusuke and Kuwabara, and he is the reason that Voldemort had to wait so long to advance in his plans. If you stay close to this boy, you will undoubtedly get a crack at Voldemort soon enough. So, I'm sending you to the boy's school, Hogwart's School of Witchcraft and Wizardry. You will masquerade as wizards from Japan, transferring to the school for a while to learn about foreign Wizarding schools."

"Wait…wizards?" Kuwabara asked.

"Yes. I know, it seems strange, and it will stay that way for a while, but I don't know enough about that world to give you more information. You'll have to rely on your contact for that. And I'm sorry if you get confused, but…I need you to stick with it, all right?"

"We'll do it," Hiei said vehemently. "We'll kill that bastard for messing with Kurama."

"Glad to hear it. But you have to realize that this is about more than Kurama now. This is about the safety of all the worlds."

+End flashback+

"Yes, yes, he did," the old man said in answer to Kurama's question. "I'm so sorry that a man from our world caused you so much pain. How is the arm?" He glanced at the sling that bound Kurama's left arm.

"Better," Kurama said, looking a bit surprised.

"The school nurse will be able to fix it when we get there. My name is Professor Dumbledore, by the way."

"So where do we go now?" Yusuke asked. "This place looks so cool!"

Dumbledore chuckled. "I have money for you here," he said, handing them each a money pouch. "Gold coins are Galleons, silver ones are sickles, and the bronze ones are Knuts. Here's a list for each of you of everything you'll need to buy and the shops you can find them at. Shop, explore, do as you wish. I'll wait for you back at the bar you went through to get here, and we will talk more when you join me." He touched a hand to his forehead in a teasing salute and walked away, leaving the four of them alone.

"Cool!" Yusuke said. "I'm gonna go look around!"

"Me too!" Kuwabara said, running after him.

"Meet us at the bar in two hours!" Kurama called after them as they disappeared into the crowd. He turned to Hiei as they vanished. "So, where should we go first?"

Hiei sighed and pulled out the paper Dumbledore had given each of them. "This thing is long!' He looked at the first line. "It says that we should get robes at Madam Malkin's Robes for All Occasions."

For the next hour and a half, Hiei and Kurama moved from store to store, collecting everything on their list. They were fitted for the odd robes first, and then they asked for the books on the list at a store called Flourish and Blotts. They bought quills, ink, cauldrons, and everything else they needed at stores with names like Magical Bits-and-Bobs, with Hiei wondering aloud all the while why they would need all this crap.

They were on the way back to the bar to meet the others when Kurama caught sight of Eeylop's Owl Emporium. "Oh, Hiei look!" he said. "I wonder why they're selling owls?"

"I don't know, but I have a feeling you're going to find out," Hiei muttered.

"Yep," Kurama agreed. "Come on!"

The inside of the little building was dim and quiet. The beady eyes of a hundred owls glared at the newcomers from all directions, and every once in a while, a soft hoot could be heard.

"Excuse me," Kurama said to the man behind the small, rickety desk by the wall. "Could you tell me why you're selling these owls?"

"Um…I'm sorry, sir, but I…" the man said, in English, a language Hiei knew little of, though he got the general gist of the sentence by picking out the couple of words he did know.

Kurama, who had learned English in school, answered instead. "My apologies, sir. My name is Kurama, and that is Hiei. We are from Japan, and I am afraid that we do not understand the customs here. Why are you selling these owls?"

The man looked puzzled, but he said, "Why, they carry mail, of course!"

"They…"

"Carry mail, yes. Even without an address, a Wizarding owl can find anyone, anywhere. I highly recommend buying one, especially since you're so far from home."

"Kurama…" Hiei said warningly.

His half-formed protest proved futile. He and Kurama walked out of Eeylop's with a third addition to their party—a snowy owl that Kurama named Sora.

"Why did you get that thing?" Hiei asked as they made their way back down the street.

"Because I did promise to write to Mother when I told her where we are going, and I love birds. So, it seemed logical."

"Okay…maybe I'll send one to Yukina…"

"You miss her, ne?"

Hiei sighed. "Yes. She's been in the ice world for three months now. We haven't been apart for this long since she found out I was her brother." He shook his head. "I'm just being sentimental. Let's go meet everyone."

Kurama and Hiei found Dumbledore waiting at the table with what looked to be a glass of soda in front of him. Yusuke and Kuwabara were sitting with him.

"About time," Yusuke said as they sat down.

"What's that?" Kuwabara asked as Kurama sat Sora's cage on the table.

"Oh, you've bought an owl!" Dumbledore said, sounding quite delighted. "Wonderful creatures, those…quite useful. I remember when I had an owl…but perhaps this is not the right time for that…" He clapped his hands together once and called, "Tom, may we have a private parlor, please?"

A short, stooped man walked over to them and bowed. "If you'll come with me, sirs…"

Dumbledore stood and motioned for Yusuke, Kuwabara, Kurama and Hiei to do the same. The little man—Tom—led them to an empty room down the hall from the bar. A fire blazed in the hearth, illuminating the armchairs set around a wooden table.

"Tea?" Tom asked.

"Please. And you four must be hungry…a plate of sandwiches with those, too, I think, Tom."

Tom bowed again and left the room, closing the door behind him.

"Come, sit, sit," Dumbledore said, waving them toward the chairs. "I'm sure there is a lot you would like to know." He sat in one of the armchairs, folded his hands in front of him, and studied the four for a long time. Finally, when Yusuke had begun to fidget uncomfortably, he spoke. "You are very strong. Physically and spiritually. You may be the answer to our prayers."

Reviewer's comments:

darkspirals: Thankies for the review! And reading fanfics is about all I do anymore, when I'm not reading or writing. It's sad, really…oh well. Gives me more time to update for you guys! Not that I do that too often, but…I try! I really do! So…review this story, too, all right? PLEASE!

IceDragonKatana: Okay, first of all, let me just say how sorry I am about your father. I know I should be spitting out some cliché thing like "As long as you keep your memories, you'll be fine" or something like that, but the truth is, I can't, because I know how awful it feels to have someone say that to you like everything is just hunky-dory. But I will say that, unlike the many people who have probably told you, I do understand how you feel, because I lost my dad when I was three. And I know you probably don't want to hear that sob story, so out of respect for you, I will shut up as soon as I say that if you ever want to talk, feel free to drop me an e-mail at And now, moving on…thanks so much for your review! It really touches me that you still go to the trouble of reading and reviewing even with what you're going through right now. I hope you enjoyed the first chapter of this story just as much, but if you don't feel up to reading, don't feel like you have to read it as soon as it comes up.

MikaSamu: Sorry, only one more fic in this mini-series! I'm trying to come up with a plot for another shounen, but according to my sister, I'm a no-talent hack who can't come up with her own plots, even though I did make up this whole series, so it's not coming along so well. Hey, if you have an idea for a Hiei/Kurama shounen story for me, send it in a review, would ya? If you don't wanna write it yourself, that is. I'd give you all the credit for the plot and I'd really appreciate it! And thanks for the review! Hope you enjoy this one too!

FireChibi: Thanks for the review! And I hope you continue to "break the pattern" for me and review this chapter, and the next one, and the next and the next and the next…okay, shutting up now…
