Hello everyone, old and new. I know that I wrote this nearly two years ago, and I have come back to take a look at it and realized…wow, I sucked. Well, I see I have a lot of reviews, so I decided that I would revamp this and hopefully get the inspiration I need to try and get the sequels done. That's would be nice, now wouldn't it? So, I plan to rewrite ALL the chapters. Yes…all, or at least as much as I can before school steals my soul. Anyways! Hopefully my writing style has improved as these revamps will keep new readers interested and make my old readers still be fans. :D I have also actually FINISHED watching the Yu Yu series, so hopefully my details as far as the characters from that series go will be better. I'm not promising anything on Harry Potter. On with the rules!

1. I do not own Yu Yu Hakusho and I do not gain any profit what-so-ever from writing this fanfiction. (Unless you want to call self-satisfaction profit, but since that has no monetary value, you can't sue me for it! HA!)

2. I'm gonna play with the ages a bit of the Yu Yu characters (well, mostly Yusuke's and Kurama's – roughly sixteen – which I think they are anyway, but anyways, that's how it is).

3. I do not own Harry Potter. All characters are licensed to J.K. Rowling and I did not put them in this fanfiction in order to make a profit.

4. All types of reviews are welcome. However, it is neither appreciated nor polite to read every single chapter and flame me for it. Criticism is nice – I like it, it helps me with my writing. However, if you are flaming me SIMPLY BECAUSE YOU THINK I UTTERLY SUCK AND THAT IS ALL YOU EVER SAY IN YOUR REVIEWS, then please don't. It's VERY rude and not what, in my opinion, is all about. And, on that note, if you think I suck so bad, why are you reading my fic?

5. Please enjoy this fic. I write them because they are fun and I think that people will enjoy them, so I hope you do.

6. Please review. :3 Reviews make people (and me) happy!

SIDE NOTES: I utterly DETEST Kawabara and Keiko. They will be bashed. You are warned. Hermoine is in here too, and kind of bashed, but still remains useful. Right.

Invitations

"Here you are sir! One double cheeseburger with extra lettuce, a large fry, and a Coke!" the chipper cashier beamed as she handed off the food to a certain green-uniformed teenager.

Yusuke idly took the tray in one hand and settled himself in a corner booth in the McDonald's restaurant. Except for himself and a few lunch break stragglers, he was alone. Slowly, he munched on his meal, staring out the large windows at the people and cars passing on the streets. It all seemed so…well, boring.

It had been nearly half a year since he had come back from the demon world and finished the Demon King tournament (as he called it). He always proclaimed how he was happy how he hadn't won that tournament, but there was always that bit, deep inside him, that wondered what it would have been like if he had won. Would he have ended up like Raizen? Would he had turned Demon World upside down? Would he have been happier than he was now?

He shook his head, shrugging off his contemplations. It wasn't healthy to think like that. He should be grateful that he was allowed to even live in the Human World. By all rights, he should be locked away in Demon World and being hunted down by King Yama's little guard squad as a class S criminal and demon. He would be able to finish his education (like it mattered), he got to be with his mother, and he got to be near Keiko. That was enough.

Wasn't it?

Growling to himself, he got up and threw away the rest of his food, no longer hungry. He ignored the to cheerful good-bye from the cashier and stepped out onto the busy Tokyo streets. People rushed by him on their way to work, engagements, and appointments – everything that made them normal. Vaguely, Yusuke picked up snitches of conversations – girls giggling over the hottest new idol, boys trying to establish dominance over one another by proving who was more 'macho' – the usual.

And again Yusuke was struck by how…boring it all seemed. Everything was so dull, as if it was black and white now instead of the eye popping colors it normally was.

"I wish I had never become a Spirit Detective," Yusuke growled, kicking a stray can as he passed it.

"Well, we all knew that one," said a calm, soft voice from behind.

Yusuke blinked at turned his head to see a familiar red head walking up to him. "Hey Kurama," Yusuke smiled gently.

The red head took a place beside Yusuke as he walked down the street, hands tucked inside his pink uniform pockets. "I am surprised you are not waiting for Keiko outside of her school. Don't you usually escort her home?" Kurama pointed out.

Yusuke shrugged. "She'll be okay today," he said. "I needed to be by myself, you know?"

"Yeah, I know," Kurama said quietly.

Together, they walked in silence for a long while. More than even Keiko, Yusuke had managed to find solace in Kurama. The fox always listened to what he had to say, always patiently, and somehow always knew exactly what kind of emotion he had to show to make Yusuke feel better. He had gone to Kurama a lot in the first few months when they got back from the tournament, but slowly he had stopped. Yusuke always kept reminding himself he needed to thank Kurama for putting up with his many temper tantrums, but never knew how to go about it. Yet Kurama seemed to understand the unsaid feelings of gratitude and had never pressed for a thank you or anything of the like.

"So, is your mother finally letting your leash go out a bit longer?" Yusuke asked.

Ever since they had come back, Kurama's mother had been clinging to him about as tight as a fly to a spider's web. She didn't let Kurama out of the house without him giving her a minute-by-minute break down of where he would be and what he was doing. He also had to have his cell phone on at all times and he had to call her every half hour to check in, unless he was at school.

"Well, yeah, a little. Right now, she thinks I'm at a club activity. Even I need some fresh air now and then," Kurama chuckled.

"You did not! Mister Perfect lied to his own mother?" Yusuke gaped (while at the same time holding back gales of laughter).

Kurama huffed. "Not like I enjoyed it," he muttered.

Yusuke just grinned and patted Kurama's shoulder, "Well, I suppose sneaking away from school was cake for a guy who used to be a S-rank thief."

"Still am," Kurama corrected. "I pulled off a heist about a week ago. Raked in about thirty million yen for it too."

"Okay, seriously, I have got to get into your line of work!" Yusuke proclaimed.

Kurama just laughed and continued walking. Although Kurama spent the majority of his time in the Human World, every now and then he got hired out by some rich demon or human or something of the like to steal a precious object. On those occasions, he let Youko out to play, and he earned big bucks for it. He didn't do it often, but it was enough to keep his family's bank accounts fat and happy, and what he didn't put into the bank account for his family he slid into another under Youko's name (he had even set it up as Youko, but with a hat on). Needless to say, when Kurama retired, he could live the high life for a good, long time.

"You know, normally you two walking together down the street isn't a good thing," a voice drawled from Yusuke's left.

"And you know, normally, you don't come out during the daylight hours," Yusuke retorted, his hazel eyes glaring a challenge at the tiny demon now walking beside him and Kurama.

Hiei glowered back, but otherwise remained unresponsive, which in turn made Yusuke pout in annoyance. It was no fun attempting to bait the little demon if he would not rise to it! Kurama just watched the exchange with a shake of his red locks and turned his emerald eyes skyward. They settled into an almost comfortable silence – as much as could be expected from Hiei and Yusuke having to share the same breathing space. The two got along, but…. well, they weren't about to have any sleepovers, that was for sure.

"So, what did bring you out of your rabbit hole?" Yusuke finally asked, stretching as they took a detour into the nearby park.

Hiei was a quiet for a moment and then began to rummage around in his cloak and pulled out a tattered looking letter. The thing looked like it had been summarily dropped in the mud, dragged through it, then gone through a thunderstorm and air dried through the glories of tornado speed winds.

"I received it this morning," Hiei said, indicating the tormented piece of parchment in his hand.

"What is it?" Kurama asked quizzically.

Hiei was quiet for a moment, mulling over what to say. "Well…I suppose you would call it an invitation." Yusuke's eyebrows rose in surprise. He hadn't know the little demon knew what that word meant, much less what an invitation might look like.

Yusuke snatched the letter from the demon's hands and unfolded it swiftly, eyes skimming the page. His eyebrows scrunched together, "What in the world is this? This has to be some kind of joke!" Yusuke held out the letter to Kurama. "Here," he said.

Kurama blinked and took the letter, not sure what to expect.

Hogwarts School

of Witchcraft and Wizardry

Headmaster: Albus Dumbledore

(Order of Merlin, First Class, Grand Sorc., Chf. Warlock,

Supreme Mugwump, International Confed. Of Wizards)

Dear Mr. Hiei,

We are pleased to inform you that you have been accepted at Hogwarts School of Witchcraft and Wizardry. Please find enclosed a list of all necessary books and equipment.

Term begins on Sept. 1. We await your owl by no later than July 31.

Yours Sincerely,

Minerva McGonagall Minerva McGonagall, Deputy Headmistress

"Where did you say you got this again?" Kurama asked, re-reading the letter.

"An owl," Hiei replied.

Yusuke sighed. "It's called the mail, Hiei. Honestly, we've explained how things work up here enough times already!"

Hiei glowered at Yusuke, "No, I really mean an owl. A large predatory bird that is nocturnal, and is best known for its eyes and keen hearing, and is often referred to as 'wise'."

"Okay, okay, I don't need the encyclopedia reading," Yusuke snarled.

Kurama handed the letter back to Hiei. "It seems very authentic," he noted. "What's more, who knows Hiei well enough…or at least, is stupid enough to try and prank him? Other than our small group, no one in this world knows who Hiei is or that he is even here."

The fox had a point. Yusuke eyed the letter until Hiei finally stuffed it back inside his coat, next to his katana. What in the world was going on? Was it possible that it was one of Koenma's rather elaborate ways of saying that they were needed for a mission? No, that wasn't it. Ever since Yusuke had been reclassified in the eyes of Spirit World as an S Class demon he was no longer a Spirit Detective. It was more like he was a criminal that the FBI was content to let stay in another country, so long as he didn't cause problems and staid out of their hair.

So, what as all this? There was no way this was real. But, then again, Yusuke hadn't believed that Demons existed until he had died trying to save a little boy and had met Botan and begun his crazy trip down the road of life as a Spirit Detective. So, what, did that mean, through his own logic, that wizards and witches were real and that there was such a school as Hogwarts hell bent on training little wizards and witches?

Yusuke groaned and rubbed his temples. It was all too much to think about right then. Out of the corner of his eye, he could see Kurama begin to open his mouth to make some sort of point, but he was cut off by the impossibly cheerful sound of his cell phone ring.

Paling the tiniest bit, Kurama dug the phone out of his pocket and flicked it open. "Mother!" he said in his best 'No, I am not up to something, whatever could you be thinking?" voice.

He was quite for a moment and opened his mouth to say something, but closed it as his eyebrows scrunched together and his lips pursed. "Now, mother, I am sure that it's just your –" again he was cut off and this time his eyebrows flew up as he listened to something on the other end. "Mother? Mother? Mother, hold on, I'll be right home!" he said and flipped the phone shut.

"What was that about?" Hiei demanded, watching the red head with an amused glitter in his eyes.

"Apparently, my mother says my house is being attacked by an owl. It came in through the window and now refuses to leave," he said.

"Owl?" Yusuke repeated. He looked at Hiei, the letter coming to mind. "If…but then…I think you have mail."

Kurama frowned seriously and nodded. "Yes," he said quiet, "I think I do." With that he took off at a dead run, heading back towards his home.

Yusuke and Hiei watched him go until he was out of sight and silence had settled around them. Yusuke sighed after a long moment and looked at Hiei out of the side of his vision, "Do you know where Koenma is?"

"No, but I can find out," Hiei said, and with that, he vanished.

Yusuke was left alone in the park, nothing around him but the silent sakura trees and the dull roar of the city. He stood where he was for a long moment, contemplating what to do. If he went to his house and there was an owl and a letter, what was he supposed to do? Was he supposed to accept the fact that there was whole other society out there besides Demon World and the Human World? Heck, he had accepted the whole Demon and Spirit World thing, but hey, he had been dead.

With sigh and a rather defeated slump of his shoulders, he turned on his heel and exited the park, heading into the concrete maze that would lead him back to his own apartment. More than likely, if there was an owl in the house, his mother was to drunk to notice, or she was asleep and still didn't notice. Either way, Yusuke just knew there was something waiting for him.

Trouble was, did he really want there to be?


Haha, yay for rewrites:D And, on a side note, I know the letter for Hiei was verbatim from the Harry Potter book. I did so because it 1) sounded better that way, and 2) gets across to first time readers that I am not joking – this is a Yu Yu Hakusho/Harry Potter cross over! Anyways, more rewrites to come!
