Chapter One:

One is Silver, the Other Gold

Diana Randall, an incoming second year at Hogwarts School of Witchcraft and Wizardry, had not slept at all the night before. Today was the day that she, along with her friends Hermione, Ron and Harry, were getting on a plane headed for Domino, Japan, where her friends Yugi, Marik, Seto and Ryou lived, and Diana couldn't be more thrilled.

Not only was she excited to meet Yugi's, Seto's and Marik's girlfriends, Diana wanted to have someone to duel besides Ron, who she always creamed. She was hoping in particular to try and duel one of her friend's Yamis, since she'd heard they were really good.

Not wanting to be late, Diana woke Ron up at 7:30 AM, causing him to be very cranky.

"Thanks for keeping me up all last night and then waking me up early," he grumbled, "I could of slept until 9, the plane ticket says so."

"That's the time the plane leaves, you idiot," Diana said, "You have to be in the plane at that time."

Ron glared. "We can always use Floo Powder."

"Don't you think that'd scare them a little?" Diana snapped, "C'mon, get out of bed and get dressed."

Ron continued to grumble as he got ready, and Diana ran into the bathroom to get dressed.

Diana came out of the bathroom five minutes later dressed in a pair of her most casual jeans, a red-black layered top with "Dangerous" in curly black handwriting, two black sneakers and matching biker gloves.

"Punk much?" Ron said dully.

Diana stuck her tongue out as she put on her black KaibaCorp baseball cap.

"It's not my fault if a lot of cool stuff is black and red," she muttered, grabbing her yellow duffle bag and headed downstairs.

Mrs. Weasley was up too, and as Diana sat down at the table, she smiled.

"Good morning, dear," said Mrs. Weasley as she put a stack of pancakes and some sausages in front of her.

"Morning," Diana greeted as she bit into a sausage.

Ron then came downstairs, tugging behind him an old, tattered suitcase. "Morning, Mum. What's for breakfast?"

Mrs. Weasley scowled at her youngest son.

"Aren't you going to at least tuck in your shirt, Ronald?" she said exasperatedly, as she did it for him.

"Mum," Ron moaned, "Knock it off…"

"You should at least look presentable if you're wearing a button-up shirt like that," Mrs. Weasley snapped.

Ron rolled his eyes, and Diana tried to hold back a snicker.

Mrs. Weasley put a smaller stack of pancakes and fewer sausages on Ron's plate, and then looked at Diana.

"Would you like some more, dear?" she asked.

"Oh no, Mrs. Weasley, I'm fine," Diana assured her.

But Mrs. Weasley wasn't paying attention; she was staring at Diana in surprise.

"What's wrong, Mrs. Weasley?" Diana asked in concern.

Without warning, Mrs. Weasley screamed.

"Diana! You're…you're starting! I can't believe it!"

"Huh?" Diana was very confused.

"You're already becoming a lady, oh, your aunt will be so pleased!"

"Huh?" Diana repeated.

"You're so early…my goodness!"

"WHAT THE HELL ARE YOU TALKING ABOUT, WOMAN?" Diana shouted.

Mrs. Weasley tried to get a hold of herself. "You're already starting puberty…"

Diana paled. "W-what?"

Diana felt her shirt, and went even whiter.

"Oh, hell no…"

Mrs. Weasley continued to scream excitedly, but Diana ran into the bathroom to make sure she wasn't dreaming. Then Ron heard the sound of someone throwing up.

Diana came back into the kitchen, looking positively ill, but she smiled at Ron like everything was normal.

"C'mon, Ron, let's get to the airport."

((You know, I read that once in a fortune cookie...))

"Dare! Ron!"

The two redheads turned to find Hermione and Harry running toward them.

"Hey, guys," Diana said in a mellow tone.

"Are you okay, Dare?" Hermione asked in concern, "You look a little peaky."

Diana attempted a small smile. "I'm fine, Mione, really…"

She shot Ron a look when he opened his mouth to speak, and he desisted.

"Well, we better get on the plane," Harry said, "Do you know where it is?"

"It's at Platform K-something, last time I heard," Ron said, "Whatever that means, these airports are confusing…"

Diana glared at Ron. "Stupid git…It's at K1."

"But the platform assistant told us the public Platforms only go up to F7," Hermione said in surprise.

Diana smirked. "I think we have a private platform…and since it's "K1", I think it's one of Seto's private platforms."

Right then, a guard in a tuxedo approached them.

"Are you four Diana Randall, Harry Potter, Ron Weasley and Hermione Granger?" he asked.

"Yes," Hermione replied, "We're looking for Platform K1."

The guard nodded. "Follow me. Mr. Kaiba was hoping you wouldn't be late for your flight, since broomsticks would be against the rules."

Diana and Harry exchanged a grin, before the four of them followed the guard down some stairs and through a metal door to the take-off area.

"Which one's ours?" Harry asked.

"That one," the guard replied, pointing to one in the corner.

Diana's eyes widened. The plane looked just like a Blue Eyes White Dragon, Seto's favorite Duel Monster.

"AWESOME!" Hermione and Ron yelled.

They walked toward the Blue Eyes plane, and the mouth opened to reveal some steps for them to go up.

"WICKED!" Harry and Diana said together.

"Glad you like it."

They got to the top of the stairs, and sitting across from a table in one of the blue seats was…

"Seto!"

Seto smiled at his friends. "Hello, all."

"This plane is so wicked, Seto!" Diana said, "How do you get this stuff?"

"You're talking to a millionaire here," Seto said in cool amusement, "How else? By telling people to make it for me."

"Well, it rocks!" Harry said with a grin.

"I like it too."

Running in was a little boy with a mop of long black hair and flashing blue eyes like Seto, followed by a girl about Seto's age with sleek black hair and warm brown eyes.

"Hi," the little boy greeted, "I'm Mokuba…I assume my big brother mentioned me already?"

He looked at Seto suspiciously, and Seto smiled.

"How could I not?" he asked, ruffling Mokuba's hair fondly.

"I assume these are the friends you mentioned, Seto?" the girl asked.

"Yes," Seto said, giving her a small kiss on the cheek before looking at the Brits, "This is my girlfriend, Melisanne. Melisanne, this is Dare, Harry, Ron and Mione."

"Hi," Harry greeted.

"Ni hao," Melisanne replied.

"You're Chinese?" Hermione asked in interest.

Melisanne nodded simply as she sat down next to her boyfriend and looking at him. "When are we taking off, Seto?"

"Soon," Seto replied, before adding to the Brits, "You guys better sit down."

The Brits sat around a Japanese-style table on the floor in blue, first-class seats, before feeling the plane take off smoothly.

"By the way, how's Kaiba Land getting along?" Harry asked.

Mokuba smiled. "It's really cool! I just wish Seto could use a little magic to make cooler-"

"Mokuba-chan, you know that's against the rules," Seto said sternly.

Mokuba pouted. "But you can't deny that would make it cooler, Seto-sama!"

Seto sighed. "No I can't, but that's not the point…"

"Then do it when you graduate!" Mokuba said in triumph.

"Not without Dumbledore-sensei's permission," Seto replied simply, "And I presume the Minister of Magic would need to know also…"

Mokuba glared playfully. "Really, Seto-sama, do you want me to have to beg from Seth-kun?"

Seto glared back at his little brother. "Mokuba-chan…"

Harry laughed. "You just can't resist your brother's pleas, can you?"

Seto rolled his eyes, and Melisanne laughed too.

"He never can," Melisanne replied for him, "Never, ever…"

"And when I do," Seto added sourly, "He goes right to Seth…"

The Millennium Rod glowed and Seth appeared in his transparent form next to Seto, looking tired and rubbing his eyes.

"Time to get up already, Hikari-chan?" Seth yawned.

"About three hours ago, yes," Seto said coldly.

"Really?" Seth asked lightly, before noticing the others, "Konnichiwa, all."

"Hi, Seth," Diana replied.

"What's up?" Ron asked.

"The sky," Seth said sleepily, before dozing next to Seto.

Mokuba burst into giggles, but Seto didn't look too pleased.

"Wake up, you nimrod!" the CEO snapped.

Seth jerked awake again. "It's too early, Seto-chan…"

"It's 9:00 AM!" Seto said testily, "You call that early?"

"Yes, as a matter of fact, I do…good night," Seth replied, before vanishing back into the Millennium Rod.

Seto sweatdropped. "I really do hate him."

"Why, because he gets more sleep?" Melisanne teased.

The conversation went on and on like this, until Diana finally challenged Seto to a duel and lost spectacularly to his Blue Eyes Ultimate Dragon.

In a little less than an hour, the Blue Eyes plane landed, and all of the British kids rushed to look out the window.

"Home, sweet home," Mokuba said with a grin.

They got off the plane, and went out into the airport, to find some more familiar faces.

"Yugi!"

"Marik!"

"Ryou!"

Yugi grinned. "Hey guys!"

Diana gave a newly appeared Bakura a hug before looking at Marik and asking, "How are the tombs?"

"They're boring, as usual," Marik replied, "If only I could use some magic to make it more interesting…ow!"

A girl had whacked Marik on the head with a rolled-up magazine. She had short brown hair, a dark tan and flashing green eyes.

"Don't you think you should set a good example for the twins?" she snapped, gesturing to a stroller in which two babies were sleeping.

"Yes, dear," Marik said sheepishly.

The girl smiled at the British kids. "Hi. I don't believe we've been formally introduced. My name's Kara."

"And I'm Kitty," said a girl holding onto Yugi's arm. She had short, dark auburn hair and hazel eyes that hid shyly behind silver-rimmed glasses. Diana also noticed her gothic attire.

"Diana."

"Harry."

"Hermione."

"Ron."

Kara smiled, and Kitty said, "Pleased to meet you."

"HEY YUGI-KUN, WAIT FOR US!"

Yugi and the others turned to see a boy and two girls running over to them. The boy was blond with puppy-like brown eyes, and the first girl had light brown hair and eyes like the blond, and the other had blond hair and bright purple eyes.

"Are these the kids you told us about, Yugi-kun?" the boy asked.

"Yep," Yugi said, before looking at the British kids, "Guys, this is Joey, Joey's girlfriend, Mai, and sister, Serenity."

"Nice to meet you," Diana said.

"Right back at ya," Joey replied.

They all met back at the Kaiba mansion for pizza and a film ("Spiderman"), and then discussed the sleeping arrangements.

"We thought we'd each host one of you," Ryou said, "Since Kaiba-kun can take care of when Artemis comes out, Dare-kun can stay here at the mansion. Mione-kun can stay with Marik-kun at Kara-kun's house, Harry can stay with Yugi-kun and Neko-chan at the Game Shop, and Ron-kun can stay with me at my house."

Diana soon found that each of the Japanese Muggles had something unique about them, and that made them quite different, and yet so similar.

Joey Wheeler (a.k.a. "Puppy" and "Dueling Monkey") had been Yugi's best friend ever since before Duelist Kingdom, and was quite a duelist himself. He was spunky, street-wise and hotheaded, and yet, to everyone with the exception of Seto (a.k.a. "Rich Boy" and "Money Bags"), he was really friendly and sweet.

Mai Valentine seemed like an odd match for Joey at first, but Diana later saw why they were meant to be. Mai was also spunky, but she was a little more of a loner and loved traveling and shopping above all else. Together, however, those two blonds could probably make through anything.

Kara, Marik's girlfriend, was very kind-hearted and a little more pensive than the others. Joey seemed to get along with her the most besides Marik and the twins, but it wasn't hard to. She was a little impatient and a perfectionist at times, but she obviously was a good friend and mother.

Kitty, as Yugi had told them, was a slight Goth. She was very shy and introvert, but as soon as she was comfortable, she was very sweet and kind, although she still had an aura of seriousness. She liked to read and write, and always seemed to be asking for paper and a pencil to write down an idea for a poem or story.

Serenity was really innocent, optimistic and loyal: almost a mirror image of her brother Joey without the temper and dueling expertise. She seemed to always be helping Kara with the twins or talking with Mai about different things (mostly shopping).

Melisanne was quiet and mysterious like Kitty, but she opened up both faster and less than Yugi's girlfriend did. While she was kind to the Brits before Kitty, she seemed to have an aura of someone always keeping secrets, but she still got into conversations and seemed at ease.

Diana fell asleep in a guest bedroom across the hall from Mokuba's with a smile on her face.

'This was the best day of my life…'
