A/N: This idea came to me and I thought…why not? Combine two of my current obsessions into one. Yugioh timeline wise, this fic is set in a semi-AU universe. Harry Potter wise, this takes place three years after the Battle of Hogwarts, in 2001.

A lot of the details will be hammered out later, but for now, enjoy baby (okay, eleven-year-old) Ryou and Bakura!

Disclaimer: I don't own Yugioh or Harry Potter.

CHAPTER 1: THE LETTER FROM HOGWARTS

Ryou Bakura knew as soon as he reached the foot of the stairs that something special had happened. He knew it as well as he knew his own name. For one, his little sister was sitting at the breakfast table looking particularly cross, her arms folded and a pout on her face. Heka, the family owl, stood on the table, pecking idly at some crumbs that Amane had set out for her. Across the table, his father beamed at him, an issue of the Daily Prophet in his hands.

He glanced down at the table, feeling his heart begin to beat.

A letter sat innocently on the table, looking back up at him. It was sealed with a four-sided seal that he knew well by now—a lion, badger, snake, and eagle. Ryou picked it up with bated breath, turning it over.

Mr. R. Bakura

"This is…" he said quietly, about to break the seal.

His father stopped him. "Ryou," he said, still smiling as he handed him another envelope. "There's more."

Ryou frowned, taking the second envelope from his father. Like his, it also bore the Hogwarts seal on the back. He turned it over.

Mr. Y. Bakura

Ryou's eyes widened in realization. "But this means…"

"I guess there's no fooling that quill they have," said his father. Makoto Bakura put down his newspaper, eyeing his eleven-year-old son from across the table. "Shouldn't you two open them together?"

Ryou stared at his father for a moment as if considering his words, then nodded once, dropping both letters on the table and running out of the kitchen. "I'll be right back!" he said.

Makoto smiled, listening to the sound of his son running excitedly up the stairs.

Yami Bakura was having a dream.

That didn't happen very often in this state. He had to sleep often—such was the nuisance of having a body again, and a child's at that—but dreams were few and far between. He had been dreaming more often lately though, evidence, perhaps, of his growing humanity. The former thief, now boy, did his best not to consider that.

Still, it was a pleasant dream. He was standing in the sands of his homeland, looking out over a familiar desert scene. The winds moved through the sands, stirring them. Oddly enough, he felt at ease.

The peace was suddenly shattered by the feeling of something small, loud, and annoying jumping onto his bed.

"Yami! Yami, wake up!"

Bakura groaned, lashing out with one arm and attempting to shove the invader away as he buried deeper into his blankets. "Shut up!" he growled. It wasn't as intimidating as it should have been—his voice hadn't yet broken in this body, and it only served to make him sound petulant, something that irritated him even more. The boy was undeterred though. He reached out, tugging on Bakura's blankets and attempting to pull them down.

He sorely regretted that killing the boy would be tantamount to suicide, considering he was the only member of this household he specifically wanted to kill.

"What do you want?" he finally asked, realizing that Ryou wasn't backing down. He cracked an eye open, staring at the currently excited fluffball. It should have been illegal to be so excited so early in the morning. He almost missed the quiet, terrified Ryou of a few years ago.

"I got my letter to Hogwarts!" said Ryou.

"Fantastic," drawled Bakura, burrowing back into his pillows. "Now I'll finally be rid of you."

"No, you don't understand!" said Ryou, tugging him back up. "You got one too!"

Bakura opened his eyes reluctantly, glancing at Ryou from under his blankets. "What?" he asked.

"You got a letter too," said Ryou. "Somehow, they know about you!"

Bakura frowned as he processed this information. He decided it wasn't particularly pressing at the moment, and lay his head back down. "So what?" he asked.

"But—don't you want to see what it says?" asked Ryou, still persistent.

"Hikari, I already know what it says," said Bakura. "Congratulations. You've been accepted into Hogwarts. Blah blah blah. Go away. I'll deal with it in the morning."

"It is morning," said Ryou.

"It's not morning until I wake up!" insisted Bakura, throwing the quilt over himself to end the conversation. The former spirit sighed in relief as he felt Ryou slide off of the bed, apparently defeated.

His relief was short-lived, however, as his hikari suddenly let out a loud shout inside his mind. Bakura's eyes snapped open, and he threw the quilt off of himself, rounding on his hikari.

"BLOODY HELL! I'M GOING TO KILL YOU!"

XxXxX

A few moments later, a disgruntled Bakura sat at the breakfast table, angrily shoving food in his mouth. He glared daggers at the boy that sat across the table from him. Ryou was smiling as he ate, despite the fact that his pyjamas were askew from Bakura springing up and grabbing him by the front of his shirt. Bakura was starting to wonder if he might not have irreparably damaged his light in some way by possessing him at such a young age. Not that he was guilty, or anything like that.

The boy was happily reading his letter.

"Mine says we have to get our books, Yami. What does yours say?" asked Ryou.

"Oh, I don't know. How about the same bloody THING?" asked Bakura. The former thief had glanced over his letter before setting it aside. Like he had told Ryou, it didn't really tell him anything unexpected.

"Yami, what did I tell you about language at the table?" asked Makoto, looking up at him.

Bakura rolled his eyes. "You aren't my father," he said. It was an automatic response by now. In the four years since Bakura had possessed Ryou and his father had taken him to a Japanese wizard to have them separated, the two had come to a bit of a truce. Bakura would get food, lodging, and the same opportunities and care provided to Ryou—minus the lovey-dovey family crap that he neither needed nor cared for—and he would obey the rules of the house…

…Most of the time.

…Maybe half of the time.

"Maybe not, youkai-kun," said Makoto, sighing. "But I may as well be." He set down his copy of the Prophet, looking over at Ryou. "Now, Ryou," he said. "I know we've been over this, but I need to ask again. Are you sure you would rather go to Hogwarts than Mahoutokoro?"

Ryou nodded once, looking suddenly serious. "I'm sure," he said.

"What about you, Yami?" asked Makoto.

Bakura shrugged. "Why not?" he asked. He honestly had no interest in getting a wizarding education, but he had the potential for it apparently, and he understood that there was no other way to get anywhere in these times. Plus, it allowed him to blend in, and although he had no current plans, he knew that blending in would likely be the first step for any plans he wanted to make.

Once he was grown, of course. This 'child' business was rather annoying.

"Then it's settled," said Makoto. "We'll head to Diagon Alley as soon as you boys get dressed."

"Why do they have to go?" whined Amane.

"You'll get your letter soon, Amane-chan," said Ryou, smiling at his sister and patting her on the head. Amane ducked under his hand, proof that she was still sulking.

Bakura ignored the display of sibling affection…or rivalry (he honestly wasn't quite sure), a thought occurring to him. He folded his arms, looking back at Makoto. "Are you travelling?" he asked. Ryou looked up, suddenly realizing that he hadn't asked that.

Makoto sighed. "Unfortunately," he said. "A colleague of mine at Mahoutokoro has some things he wants me to look at.

"Great, you're all leaving," said Amane, folding her arms. "Are you leaving me at Granny's again?"

"No, Amane-chan, this time you're coming with me," said Makoto, smiling at her. "I'm not doing anything dangerous this time around."

"Coming with you to Japan?" asked Amane, with wide-eyes. "But there are monsters there!"

"Don't get eaten," said Bakura with an evil grin, leaning forward across the table.

Amane's eyes widened and she shrank back, but then she scowled, glaring at him. "Yami, stop teasing me!"

"Don't worry," said Makoto, reaching over and taking a roll. He buttered it, not even looking up at them. "You've already seen the scariest thing there."

"I'm from Egypt, old man!" corrected Bakura, turning towards him.

"Right, of course, oh great thief king," said Makoto. "Would you like some more milk?"

Bakura scowled and glared in reply, his eyes flicking towards his glass, which was indeed empty. He folded his arms, settling back into his seat. "Yes please," he reluctantly replied.

A few hours later, the four of them were in Diagon Alley, Bakura and Ryou both carrying bags of school supplies. The pair had already gotten fit for their uniform robes, where Bakura had to endure Madam Malkin's constant cooing over "what a cute pair of twins" Makoto had. They had also collected their books at Flourish and Blotts', and Bakura had practically had to drag his light out of the bookstore. Ryou, predictably, wanted to read everything. A set of crystal phials, scales, a cauldron, and a brass telescope later, and all they were looking for was a wand.

And a pet. Makoto had insisted that if he and Amane were going to be in Japan for the school year, the pair would need at least one owl between them. But they were going to get that last, and as far as Bakura was considered, he could care less about the pet.

He wanted the wand.

It didn't take him long to figure out that magic in this world was power, and that if he wanted power, he would need to have magic. It had been explained to him that since he was never technically born, at least not in this time, he might not have been listed for Hogwarts, but now that he was, it had opened up so many doors. The possibilities were literally endless.

But before he could become a wizard, he would need a wand.

And that brought the four of them into the cramped, musty shop that was Ollivander's.

Ollivander himself shuffled out to meet them. He looked more tired and worn since the events of three years ago had occurred, but there was still no better wand maker in England. His eyes fixed on Makoto as he entered.

"Makoto Bakura," he said, quietly. "I never made your wand. It was cherry and kitsune hair, wasn't it? Murasame make?"

Makoto smiled, nodding once. "As always, your memory astounds me, Mister Ollivander," he said.

"I remember that wand," said Ollivander, smiling and nodding as if he had thought of a fond memory. "I remember Alice's wand better. Laurel and phoenix feather, eleven and a half inches, surprisingly rigid." He shook his head. "Such a shame…" he said quietly. "We lost so many…"

"Indeed…" said Makoto, a solemn frown on his face as he nodded. Ryou's expression grew solemn as well, and he gripped Amane's hand tighter. Bakura leaned against the wall, watching them. The moment of silence passed, and Ollivander looked up.

"But enough of that," he said. "Are these your children."

"Yes," said Makoto, nodding. He motioned Bakura over, and the former thief shoved his hands into his pockets, walking up to them. "This is Ryou, Yami, and Amane." He released Amane's hand just long enough to put a hand on Ryou and Bakura's shoulders. "These two need wands today."

"Ready for Hogwarts, are we?" asked Ollivander, chuckling to himself. "Don't worry. We'll get you sorted right away. Let's start with the elder."

"You're up," said Bakura, folding his arms and taking a step back. He had no qualms relinquishing the role of elder "twin" to Ryou. It was technically true. Ryou's body was older than his, even though his mind was thousands of years older. Ryou stepped forward somewhat nervously, facing the man.

"Extend your wand arm," said Ollivander.

Ryou obediently extended his right hand. Immediately, a pink tape measure began moving, taking his measurements as Ollivander walked away, muttering to himself as he examined the shelves around him. He pulled out a box a few moments later, handing it to Ryou.

"Walnut and phoenix feather. Thirteen inches. Pliable. Try it."

Ryou picked up the wand, awkwardly moving it around. A series of sparks fizzed erratically from the tip and Ollivander shook his head, taking the wand from him. "Too versatile," he muttered under his breath, putting the wand back on the shelf and pulling out another.

"Try this," he said. "Redwood and dragon heartstring. Twelve and three-quarter inches. Sturdy."

He took it. Almost immediately, a bolt shot from it, shattering one of the nearby vases. Ryou went red, stammering an apology. Ollivander reacted only by shaking his head again, taking the wand from him. "And that was too forceful…" he said to himself, staring at Ryou. "Now, then, Mister Bakura…what sort of wand would best fit you…Hmm…I wonder…perhaps…yes, worth a try..."

He walked off. Bakura watched as he picked a small, slender box off of the shelf. He opened it, offering it to Ryou. The wand inside was white and surprisingly slender. As Ryou reached for it, it seemed to roll over, avoiding his fingertips. He pursed his lips and grabbed onto it, drawing it from the box. "Hazel and unicorn hair, thirteen inches, flexible," he said. "Give it a try."

Ryou took a deep breath and nodded, waving the wand in an arc.

Threads of silver erupted from the tip, coiling in a circle around him, accompanied by the sound of tinkling bells. "Yes!" said Ollivander. "Yes, that's perfect. Hazel and unicorn hair…now that's a combination. That wand will stay loyal to you for as long as you live, boy. It will be used by no other, and it will die with you."

"I like it," said Ryou, smiling as he put the wand back in the box. "It feels warm."

"It's chosen you," said Ollivander. He closed the box, handing it back to Ryou. He took it with both hands, walking back to his father.

The wandmaker looked up. "Now for the other one," he said.

When Bakura stepped forward, Ollivander frowned, peering at him from over his glasses. At length, he shook his head, making a 'tsk'ing sound under his breath. "Makoto…you've been messing with old magic again, haven't you?"

"Ah, you've caught me," said Makoto with a smile. "We had a bit of an accident about four years ago, with an artifact I brought back from Egypt, but all's well that ends well."

Bakura glared at Ollivander. The effect wasn't very intimidating, considering he was in an eleven-year-old body and had to look up to glare, but the effort was there nonetheless. Ollivander only shook his head. "You don't scare me, little thief," he said. "Let us see what wand fits you."

Unlike Ryou, it took Bakura much longer, and several more broken objects, to find his perfect match. Ollivander put away the sixth wand, shaking his head. "I would have thought chestnut and dragon heartstring would have worked…" he commented, turning around and looking through the shelves. "But not to worry. I've worked with the difficult before…" He extracted another box from the shelves. He handed the box to Bakura, opening it and presenting the wand. It was thicker than Ryou's, and was made of a reddish brown wood.

"Yew and dragon heartstring. Twelve and three-quarter inches. Unyielding."

Bakura frowned, reaching down and taking it. As soon as his hands closed around the handle, he felt fire move through his veins, the wand immediately pushing back against him. He grinned, feeling the wand test him as power rushed through him, and he raised it, pointing it at the wall. Flame poured from its tip, flaring up in front of him and twisting into something that vaguely resembled a dragon before dissipating, leaving behind the smell of smoke.

"Well," said Ollivander, apparently unsurprised by the display. "That settles that."

Bakura placed the wand back in the box, still grinning. Ollivander shut the box, handing it to him. "I'd be careful with that one," Ollivander cautioned. "It might be a little temperamental. But I'd wager that you're familiar with that."

"I can handle it," said Bakura, with a nod. He walked back to the assembled group, still grinning to himself. He couldn't wait to try this one out.

"That will be fourteen Galleons total," said Ollivander to Makoto.

"Of course," said Makoto, nodding. As he paid, Ollivander glanced at Amane. The girl took a step back, inching closer to Bakura.

"I suppose I'll be seeing you again shortly for the young lady?" he asked.

"Two years," said Makoto, with a grin. "If I can't convince her to attend my alma mater."

Amane's response was to grin, sticking her tongue out at her father. Ollivander accepted the gold from Makoto with a nod, watching as the family of four left the shop.

"Misters Bakura and Bakura," he called, just as the boys were about to leave.

The two of them frowned and glanced back at him, Ryou's expression confused and Bakura's slightly annoyed.

"Take care of those wands," said Ollivander. "They'll serve you well in these times."

There was a pause, and then the both of them broke into grins, Ryou's cheerful and Bakura's cocky.

"Of course," said Ryou.

Bakura only responded with a nod, following his hikari and the family out the door.

Notes:

[1] Youkai – Meaning 'demon' or 'spirit' in Japanese. The –kun added to the end of it is an honorific usually used for male children or teenagers. Put together, 'youkai-kun' is an affectionate nickname used by Ryou's father for Bakura.

[2] Ryou's wand – Wand wood and core info obtained from Pottermore. You can also find the wood info at pottermorespoilers(dot)tumblr(dot)com(slash)post(slash)9770067306(slash)wand(dash)woods. A special note is that the hazel/unicorn hair combination is extremely loyal to its owner, as Ollivander points out.

[3] Bakura's wand – Information comes from the same site as above. You can also look at that site to see why Ollivander thought chestnut with dragon heartstring would have worked. I considered it, but it would have been too easy, especially since Bakura was more motivated by revenge than by greed. Yew and dragon heartstring is also noted to be one of those hazardous combinations (strong core plus volatile/strong wood), which might explain why Ollivander didn't choose it at first, but it fits Bakura, especially since the Millennium Ring is also noted to be one of the only items that will attack whoever tries to wield it if they don't feel that they're strong enough.
