[[[Okay, so I don't own either Harry Potter or Yu Yu Hakusho, but that's okay because I don't have to own them to write fanfics about them.

You all may think that a HP YYH crossover would make a really weird fanfic, but please try it out, cause I love writing and you just might like this story. As always, of course, I have NO idea where this fic is going yet, but we will both see! PLEASE REVIEW if you feel like it.]]]

[[[also, this fic takes place when all the main characters are about 15 or so . . . It really doesn't matter what year, as it doesn't go with the plot line of the books anyway.]]]

Chapter 1: An Unlikely Likeliness

As the sun was swallowed beneath the dreary English clouds, a ruby red train pulled into platform 9 ¾ of the London train station. With its arrival, the group of hundreds of anxious students, many already dressed in their long black school robes, seemed to be electrified by pure excitement. This train was to take them all to school, a place that most children loathe to return to. Yet these students were not attending a regular boarding school. No, Hogwarts School of Witchcraft and Wizardry was anything but regular.

The only students not enthusiastic about the train's arrival were four young boys standing separately from the rest of the students in a semi circle at the edge of the platform. Although none of them had been there before, or even to England before, they stood as if they owned the very ground they stood on.

The rest of the students, not knowing the foreign boys, and seeing the glaring look that the shortest of the four had for anyone who came more than ten feet from them, courteously ignored them. But the boys couldn't care less; none of them were very confident in their English anyway.

"This is by far the worst mission we have EVER been sent on," the tall, orange haired boy muttered as he lifted his giant trunk onto his shoulder as if it didn't weigh anything at all.

"Remind me to kill Botan next time I see her," the surly looking dark haired boy snorted.

As the train filled with the chattering students, Yusuke, Kuwabara, Hiei and Kurama unwisely waited until they were the last students left to board. When the line inside the train dissipated as students found their ways into their own little rooms, the four Japanese boys were left in the train corridor with no place left to sit.

"Well shit," one of them cursed.

"Calm down, there has to be room somewhere for us," the green-eyed beauty with long red hair declared, used to being the rational one of the group. "We are supposed to be meshing with these kids anyways."

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

In that same cart, four other kids sat comfortably in their own cabin of the train. They had learned long ago not the waste time boarding the Hogwarts Express. The Express waits for no person.

As the train lurched into motion, they listened as the four unknown boys conversed in the hallway, apparently in a different language.

"What the bloody hell are they saying, anyways?" Ron whispered with a confused look contorting his boyish nose. "Is that Chinese? Great, we have China-men invading our school now."

"Oh shut up, Ron," Hermione hissed back, trying to listen into the four boys' conversation. "They're saying something about sitting down . . . and kicking some little kid's ass."

Harry, Ron and Neville stared blankly at the frizzy haired know-it-all.

"You speak Chinese?"

"It's Japanese, Ron, and I understand it now." She pulled out her wand and pointed it at her friend's bright red head. He stared down the wand with fear creeping into his expression. Hermione was scary with a wand sometimes.

"Languanius Japano!" she muttered, and two thin red threads of light snaked their way from the end of her wand to the frightened Ron's ears. Harry and Neville watched, astonished, as the ribbons of red glittered with what they thought looked like golden Japanese symbols.

"Hermione, you study way too much over the summer, you know," Harry joked as the charm broke away from her wand and fluttered through Ron's head.

"It's a real simple charm, I can teach it to you. Or you could read the book I found it from. I learned all sorts of languages from it. Japanese, German, Chinese, Italian, even Hebrew. Course the spell only works a few hours the first time. To get it to stick, you really have to . . ."

"Hey! Shut up, I can hear them!"

"What are they saying, Ron?!" Neville practically bounced in his chair with excitement.

"Well one of them just said some really bad curses and threatened one of the others with something called a katana. Don't know what that means . . ."

"It's a sword," Hermione answered with a puzzled look. "Hmmmm . . ."

"I'm gonna invite them in," Harry suddenly announced, starting for the door.

"What?! No!"

"They sound scary!"

"They haven't got a place to sit, and there is plenty of room here! You know these seats are enchanted to expand when more people sit on them!" He stared down his friends with his bright green eyes, determined not to let the language barrier or nationality difference force the new kids to stand in the corridor the entire trip. Harry reached for the door handle again, but Hermione caught his arm.

"I agree Harry, but maybe we should all use the language charm first, in case they don't know much English."

"You're right."

"Count me out," Neville squeaked. "I'll just go sit with someone else for a bit."

Three minutes later, Harry spoke, wrote and understood Japanese fluently. He unlatched the cabin door a little timidly, while Neville squeaked behind him. The door zipped open and he stepped outside to meet four sets of surprised eyes staring him down. Using Harry as a human shield, Neville slipped out of the cabin with another squeak and walked quickly down the corridor to the next cart.

"Uh, Hi," Harry spoke in perfect Japanese, though his glasses were slipping down his nose on the sweat forming on his pale face. "Are you guys looking for a place to sit? Cuz there is some room in here if you wanna come in."

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

As if the four boys weren't surprised enough to see the lanky, black haired boy step out of the room in the first place, his ability to speak Japanese down right confused them. And his daring kindness to ask them inside.

Kurama and Yusuke glanced sideways at each other, as they often did when they both needed a little reassurance when making decisions.

"Thank you, we would be honored to sit with you. My name is Kurama, and this is Hiei, Yusuke and Kuwabara."

"Uh, well, my name's Harry, and in here, err, are my friends Ron and Hermione."

"It's nice to meet you, Kurama," Hermione suddenly appeared at Harry side, her arm stretched out to shake the red head's hand, and her cheeks pink with embarrassment.

"You must be Hermione," the suave fox spirit cooed, taking her hand and giving it a gentle kiss. "The pleasure is all mine."

At his side, Hiei humfed with indignation at his friend's flirting. But the two young students' blushing stare down was broken short by a frustrated Yusuke.

"Right, well, I'm ready to sit down now. Doesn't matter where," he shoved past the two, elbowing Kurama's hand out of the way.

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

After all of the kids were settled into the cabin, every other cabin of the cart opened with curious heads poking out of each room.

"Who are they?" the students whispered across to each other.

"No idea."

"Harry was speaking a different language!"

"Maybe he's more than a Parsel Mouth!"

"Those guys were scary!"

"Who are they!?"

"We DON'T KNOW!"

The train flew across the beautiful European landscape, cutting through plains of fields and ranges of mountains so beautiful Kurama could almost forgive Koenma for sending him on this crazy mission. He and his three team mates spent the rest of the ride making small conversation with the three English teens, all who seemed to speak perfect Japanese. After an hour and a half, however, the freckled red head began to stutter as he spoke and his grammar became broken and stressed.

"Ron, you need another go at it," the puffy haired girl announced, enthusiastically pulling out a thin stick from her robes. "Here let me . . ."

"Me can myself do it!" he protested as best as he could, pulling out his own stick.

As the four newbies watched with wonder, interest, and something of fear, Ron renewed Hermione's charm on himself. Kuwabara flinched as the ribbons wound from the wood into the kid's ears.

"What the hell was that?" Yusuke demanded as the last of the red and gold threads slipped into Ron's head.

"Witchcraft," Hiei predicted, his arm twitching toward a sword that wasn't hanging on his belt. Damn that Botan, he thought, wishing for his katana once again.

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

"Well, yeah, its witchcraft," Harry said, looking rather confused at the reaction of the other boys. "You guys aren't muggles are you?" At that question, the boys looked even more confused; Harry tried to explain. "Don't you guys know magic? You have to in order to get into Hogwarts, even to get through the barrier to platform 9 ¾. Didn't you get your wands?"

Totally confused, and pissed off by the way Harry spoke as if all of this should be obvious, Yusuke started to say "No, we don't know magic, or what the hell you are talking about," but was cut off by his quick thinking friend.

"Yes, we know magic," Kurama sort of lied, "but not the kind that you know. We usually don't use wands to do our magic, and we really only know spells for fighting purposes. That's why we decided to transfer to Hogwarts. Perhaps we need more school supplies than what we were given. Are wands necessary with your magic?"

"With most of it," Hermione replied, her cheeks reddening again as they did most times she talked to the green eyed boy. "Don't worry though; I'm sure that Professor Dumbledore can help you out somehow."

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

When the train finally reached its destination, the two groups split up to take different coaches, which Kuwabara loudly declared were pulled by nothing ("But there's nothing there! How are we moving?! Where's the horse?!").

On the way up to the castle, Yusuke and Kuwabara discussed how badly they planned to pummel Koenma and Botan for throwing them into this mission with just a ten minute briefing, while Hiei sat silently by Kurama, who stared out the window, watching their approach to the intricate castle.

The coach in front of them, which carried the only people who, as of yet, had had the guts to even say hello to them, was filled with hurried whispers.

"I don't know, that Kurama seemed alright to me, at least."

"Of course he did! He was putting the moves on you, Hermione!"

"I think they are okay, but I don't think they are telling us everything."

"He was NOT putting ANY moves on me!"

"Yes he was!"

"No he wasn't . . . and so what if he was?"
