Okay, to specify, Bakura is Ryou, and his yami is Bakura, like almost every other story. It makes things easier, and as I am a lazy typer...

I don't own YuGiOh. I don't own Harry Potter, and as I stated before, I wish I did...

Oh, and I hope I didn't cram things in too much...

~*~*~

"You're my grandpa's friend?" Yugi asked the old man who had called himself, uh, Dumble-something...

"Yes, I am, one of them. All the teachers here are. We think very highly of your grandfather, Yugi Mutuoh."

"Teachers?" Anzu questioned, confused, and a litle dazed. She still half thought this was all a dream.

"Oh yes, Hogwarts is a school."

"Hog what?" Jou raised an eyebrow.

"A school for what?" Yami asked politely.

"Magic, witchcraft, wizardry, whichever you'd prefer to call it." Dumbledore waved a hand at this. "Now, I know I must explain everything to you, but would you mind if we talked and walked? We have the Welcoming Feast and Sorting to attend."

"Feast? I'm there!" Jou got a little excited. Dumbledore smiled and started to lead them around the building.

"A school for wizards? But we're not wizards. And why couldn't some of us see the castle?" Seto was still doubtful. 'This is just a highly convincing hallucination.' He told himself.

"Quite simply, of course, you have no direct connection to any form of magic. But Yugi's Yami seems to have broken that spell, at least for you. However, if he'd've waited for me," his eyes twinkled, "It could have been done without so much pain."

A couple of glares were thrown in Yami's direction. He just shrugged.

"Well, I guess before I explain anything to you, I must reveal that there is entire world of magic concealed from muggles."

"Mug what?" Jou raised another eyebrow.

"Muggles are non-magical humans." Dumbledore smiled.

"Whoa...so wait, there's an entire world?" Honda was more acceptive of the whole thing.

"Yes, and it has been increasingly difficult to hide this world from muggles." They followed him through a side door, and up a set of stone steps. He continued. "And in our magical world, we have everything that reflects the Muggle World, but is slightly altered. Clothing, entertainment, education, and, unfortunately, criminals."

"Criminals?" Ryou's eyes widened.

"Yes, and currently, the Magical World is in fear, for the one who is considered the most evil wizard of all time, has returned."

"Returned from what?" Yugi was curious.

"A complete state of powerlessness, some even considered him dead." Dumbledore seemed a little more depressed all of a sudden.

"Who is he? Does he have a name?" Anzu asked.

"His name is Voldemort. But I must say, that many people are afraid to call him that."

"Why?" Seto was kind of enjoying his delusion.

Dumbledore simply shrugged.

"Then what do they call him?" Ryou asked.

"The Dark Lord, He-Who-Must-Not-Be-Named, You-Know-Who..." Dumbledore rambled off.

"You-know-who?" Anzu raised an eyebrow.

"Yes, You-Know-Who."

"I don't know who." Jou scratched his head.

"As you can see, that gets highly confusing." Dumbledore shook his head. "So, if you would please just refer to him as Voldemort. Granted, you may draw some stares from your peers."

"Our peers? Wait, what does all this have to do with us?" Yugi asked.

Dumbledore smiled again. "You see, we have heard of the great exploits of the King of Games. How he can beat anyone at any game, win any challenge."

"Cool, Yami, we're THAT famous." Yugi smiled.

"Now, our great criminal, Voldemort, hates to be challenged. He believes that he is the greatest of all wizards, that no man may challenge him, and win."

"And you think Yugi and I can?" Yami finished.

"We were hoping that you would challenge him at some sort of Shadow Game, win, and as a game penalty, seal his soul away for all of eternity."

"My grandpa told you that we can do all of that?" Yugi said lightly.

"Yes."

"Cool." Yugi smiled again.

"Now, it will take a great amount of time and energy to put our plan into effect, so that no innocents will be harmed, especially Harry Potter." Dumbledore explained.

"Harry Potter?"

"Oh yes, you will meet him soon. He is one of the students, a famous one in the Wizarding World, and he was the only one to ever escape Voldermort alive, let alone four times. He is the one that Voldemort wishes to destroy the most, and Harry will most likely end up getting caught up in this all somehow. He and his friends always do." Dumbledore's eye twinkled with a smile. Yugi was beginning to like him. He seemed to be nice.

"Now, will you help us?" Dumbledore sounded almost like he was begging.

Yugi looked at Yami, who nodded. "I...yeah, sure, oh course we will."

Dumbledore looked greatly relieved. "Now, we were hoping to enroll you as students. Obviously, as most of you are non-magical, you will not be learning magic."

"Aww..."

"Instead, I will be teaching you personally, from the curriculum from your own Domino City High School. English, obviously, as your foreign language, mathematics, Japanese literature and history - I can speak Japanese - science, and if you wish, physical education and the arts. However, as I am none-too-skilled in those areas, some of the other teachers will bestow their expertise upon you."

The group came to a stop outside a set of tall wooden doors. They could hear what seemed like a large crowd on the other side.

"Wait a minute, your saying that we're gonna spend the entire year here? Like live here, too?" Anzu's eyes widened.

"Yes." Dumbledore nodded.

"But what about our other friends, our families?" Anzu demanded.

"They have been informed that Yugi's grandfather has given you the chance of a lifetime to attend an exclusive boarding school for a year, for free. They agreed immediately." Dumbledore reassured them.

"But what about my company?" Seto suddenly remembered. "I was only supposed to leave for a week."

"As I understand, your brother Mokuba will be taking care of it."

"HE'S 10 YEARS OLD!"

"We've already spoken to our Ministry of Magic and yours. They will be keeping an eye in him and on your company."

"How can I trust them?"

"They do not wish for Voldemort to take over the world, either, and if protecting a muggle software company helps, so be it."

"But why us?" Seto asked, agonized. "I mean, I can understand Yugi and Ryou for their yamis, but why do I have to stay?"

"Well, according to Sugoroku, Yugi is rarely happy without his friends."

"I'm not a friend." Seto scoffed.

"Of course you are, Seto." Yugi smiled his cute-little-boy smile, that the fandirls all gush over and make way too big a deal out of.

"..." Seto just stared.

"I'd thought it would be fruitful for Yami to have you around. In which case he has the Japanese National Dueling Champion and World Favorite at his side."

Seto glares at Yami, who glares back.

"And I'd thought it would be an interesting project for the school, especially for the Muggle Studies classes...foreign muggles and all..." Dumbledore's eyes twinkled again. "Anyway, we've been standing here for a great long time, why don't we enter?"

And he pushed open the huge double doors, and every person in the huge room swung their heads around to see who'd come through with Dumbledore.

Yugi and his friends were amazed and simply stunned. There must've been two hundred people in there, mostly students in black robes, but at the front table, where Dumbledore was leading them, sat about another two dozen adults, in robes of their own colors.

Yugi looked up to the ceiling and nudged Ryou in the shoulder. His pale mouth dropped open. There was a ceiling, but it swirled. As in, SWIRLED with clouds. Seto looked up, too.

"I doubt that even the dunderheads at my corportion could make a hologram that real..." He was amazed.

Dumbledore lead them up to the front, where they stood towering next to a bunch of kids, no older than eleven, who looked just as nervous as they did to be standing up there in front of everyone.

Dumbledore took his seat at the center of the front table, and nodded at a strict-looking woman, who placed a very tattered pointed hat on a rickety wooden stool.

She began calling out the names of all the little kids next to them, alphabetically, and one by one, the group of kids disappeared, all sitting first at the stool, placing the hat on their heads. Yugi nearly yelped out in surprise when he heard the hat talk. It would cry out one of four different names: Gryffindor, Hufflepuff, Ravenclaw, and Slytherin. They all noticed that whenever a kid was called down to Slytherin, the other tables would hiss and boo. When the kid was named one of those four, he or she would sit down at one of the four long tables in front of the teachers' table.

Finally, it was just them at the front. Dumbledore stood up, and started to address the crowd.

"This year, Hogwarts is proud to welcome some new students from Japan. They are Muggles, but some of you maybe familiar with them."

With the announcement that they were muggles, everyone seemed to rise into shock. Whispers flooded the room, and one table in particular seemed to get angry.

"Now, they will not be learning the same lessons as you will be, they will not be learning magic. So there is no need to sort them. However, they do need a dormitory to sleep in, a table to eat at, and possibly, a place where they can feel comfortable about asking questions about magic. Do we have a House that will volunteer for this?"

The one table that had booed the most for the Slytherins began to cheer, as if they wanted the job.

Dumbledore held out his arms to calm them down. He turned to Yugi and his friends. "Well, then, Welcome to Gryffindor. Professor McGonagall, if you would please introduce them to their new housemates."

Professor McGonagall nodded and started to read from her paper again. "Bakura, Ryou. Fifth year."

Ryou froze and turned to his yami. Bakura just let a out a wide, obvious yawn, and sank back into the Ring. Everyone gasped. One redhead at the Gryffindor table turned to his black-haired, forehead-scarred best friend.

"Can muggles do that?" His friend shook his head furiously as Ryou readed down to the Gyffindor table.

"Hiroto, Honda. Fifth year." McGonagall read. Honda stepped forward, shrugged, and followed Ryou, sitting down next to him.

"Kaiba, Seto. Seventh year." Seto strode his way down, still hoping he would wake up soon. All the Muggle-borns in the Great Hall, however, were stunned to hear the name of the famous Japanese millionare.

"Katsuya, Jounouchi. Fifth year." Jou grinned at the Gryffindor table, and walked down to sit across from Seto.

"Mazaki, Anzu. Fifth year." Everyone clamored up to get a better look at the only girl of the group. She walked over and sat down next to Jou.

"Mutuoh, Yugi. Fifth year." The Muggle-borns started up again. They'd recognized the World Champion of the Duel Monsters Tournament.

Yami raised an eyebrow at McGonagall and she spoke again. "And Mutuoh's yami, er...Yami...Mutuoh.

Yami shook his head and Yugi surpressed a laugh as they walked down the table together.

"I should've just gone back into the Puzzle like Bakura." Yami sighed as everyone in the room turned to get a better look at what a 'yami' was.

~*~*~

Hey, cool, a purpose and a plot, sort of, sorry, if I explained everything too quickly, but i was thinking realistically. If I'd've seen a castle appear out of nowhere because a 5000 yr old spirit gave me a massive headache, I'd want some answers, too, and fast...

Oh yeah, I put most them in fifth year, because if they don't get to be good friends with Harry, it completely defeats the purpose (even if they won't be having classes with them. Damn, my undefeated purpose was just defeated again...by my own contradictions...). Plus, they're that age anyway, freshmen or sophmores and such. I put Seto in seventh year because he's supposedly 18 yrs old, a senior in high school, basically, and seventh years are at the same level of high school seniors.
