By Moonlight

Disclaimer: I don't own Harry Potter, nor do I own Yugioh, much as I'd love to.

Summary: The thing werewolves fear most is moonlight. Remus Lupin is no different. But with the Marauders at his side, what is there to worry about? Two foreigners come to England, one with the complexion of moonlight . . .

Warnings: Yaoi (slash) and a little angst. Sirius/Remus Seto/Ryou – also oldies Albus/Minerva. These pairings kick-ass! I love saying 'kick-ass' for some reason . . . maybe because I'm too lame to think of anything else. Oh well, it'll do until I can think of something else. Maybe a bit of swearing. I haven't written a plain Seto/Ryou since . . . well, for months now. It's always Ryou and someone else first and then Seto/Ryou at the end. About time I wrote for only them! OOC

Author's Notes: I love Harry Potter and I love Yugioh. That's why I decided to write a crossover. My favourite HP characters are McGonagall, Dumbledore, Sirius and Remus! My favourite YGO characters are Ryou, Seto, Ryuuji and Malik. Eight kick-ass characters!

Oh yeah, this fic is set in the time of the Marauders, that is, Harry, Hermione and Ron etc do NOT exist. I don't particularly like them, actually. I like the previous generation of characters better – they're cooler!

Chapter Two: Warmer than Home

--------

The door to number 12 Grimmauld Place was thrown open with a huge 'bang!' by an enraged teen. Shouts and roars were heard from inside, as well as shrieking, when the black-haired teen stormed out, school trunk in tow. Sirius Black strode out, throwing out his wand arm.

The Knight Bus came into view and he barked instructions, handed over some money and got on. A couple came running out from the house, the man shaking his fist and shouting something. The woman was shrieking at the top of her lungs, hands on hips.

"SHUT UP WOMAN!" Sirius roared at her. He had thrown open the bus window and stuck his head outside. "I DON'T GIVE A DAMN WHAT YOU THINK!"

With that, he went back inside and slammed down the window. The bus driver started the engine and they sped off. Huffing angrily, Sirius sat down on one of the beds next to his school trunk. No one dared talk to him.

"Stupid woman," he cursed. "Don't give a damn about pure-bloods."

"Sirius, you ran away again."

Sirius looked up. Sitting across from him was Remus, smiling wanly. The gentler teen was watching him in exasperation as he bad-mouthed his parents and family. Sirius grinned back at him sheepishly.

"Yo, Remus," he said.

"You really should keep your temper in check."

"I want to, seriously," Sirius protested. Remus raised an eyebrow. "Well, all right, I don't do much to keep it in order. But it's all their fault, I swear! If they didn't make me so angry . . ."

"Sirius."

"All right, all right. Sorry, Remus."

Remus leaned on his battered school trunk and regarded Sirius with a sigh. The teen was unruly and had no heed for rules, which was why he constantly got into trouble. He had an inflated ego – not as inflated as James', granted, but inflated nonetheless. Remus frequently wondered how he was going to be able to watch him, as he had been instructed by Dumbledore to do. Instead of making sure they didn't get into trouble, or cause it, he found himself going along with whatever they did.

"On brighter note," Sirius said suddenly, "James and I think we've got the gist on how to actually escape from the castle into Hogsmeade."

"Sirius," Remus hissed. "Not so loud!"

"Hehe, sorry."

"Sometimes I wonder if you know when it's time to shut up about certain topics in certain places," Remus sighed. "It gets us into trouble more often than not, you know."

"I know, I know." Sirius leaned back onto his trunk as well, expression cocky. "Why don't we reminisce about old times?"

"Like what?"

"Like how James took off Snivelly's pants," the other teen snickered.

"That was just plain stupid," Remus sighed, rubbing his forehead. "We got into so much trouble by Professor McGonagall afterwards."

"I didn't hear you complaining at the time."

"That's because – well, it was still wrong."

"Admit it, Moony, you enjoyed it."

"Looking at Snape's greying underwear? No, I didn't."

"You liked it."

"That's gross, Sirius."

--------

"OI GUYS! ABOUT TIME!"

James bounded over like an overly hyper puppy as Sirius and Remus got off the Knight Bus, looking slightly green. They had almost crashed into another double-decked bus on the way here, narrowly avoiding almost ten sheds in the countryside and nearly killed God-knows-how-many animals.

"I must say, the Knight Bus isn't a transport I'd choose willingly," Remus said weakly. "I'm just glad we got here in one piece."

"Ditto," Sirius agreed. He turned back to the driver on the bus. "THAT WAS THE WORST BLOODY EXCUSE FOR DRIVING I'VE EVER SEEN!"

"I'D LIKE TO SEE YOU DRIVE!" the driver roared back. "AND I GOT YOU HERE, DIDN'T I? WHY CAN'T YOU TEENAGERS SHOW SOME RESPECT FOR A CHANGE?"

Sirius made an extremely rude gesture as the Knight Bus sped around the corner, tyres screeching. Remus and James hit him over the head. They went inside, greeted by James' parents enthusiastically. Remus loved this place, as Sirius did as well. It was warm and inviting and there seemed to always be love everywhere. Certainly their houses weren't the same.

"I heard you arguing with the Knight Bus' driver, Sirius," Mrs Potter said, looking at the culprit sternly. "What was that all about?"

"Uh – well, you see . . ." Sirius muttered sheepishly. Remus and James grinned at each other. Mrs Potter was the only one who could make Sirius stutter. ". . . Uh, his driving was bad?"

"And that gives you reason to yell at him?"

"Uh – no?"

"Do you admit you did something wrong?"

"Yes ma'am."

"Good boy."

With a wicked grin, Mrs Potter patted Sirius on the head fondly and walked back into the kitchen. When she disappeared, Remus and James cracked up. It was amusing to see big headed Sirius acting ashamed and sheepish about doing something wrong. Sirius flushed angrily and resorted to chasing them around the house when they didn't stop.

They ran up to James' room and collapsed on the floor, tired out.

"Mate, that was uncalled for," Sirius panted. "You guys are so evil."

"My mother can keep you in check no problemo, buddy."

"Still, you have to admit, it's rather amusing to see you admit to doing something wrong," Remus added.

"Hey, I don't think that's very nice, Moony," Sirius complained.

"You don't even stumble when McGonagall catches you in the act," James pointed out. "As I always say: GO MOM!"

He dodged an aptly thrown Quidditch figurine, laughing. Remus grinned as he watched his two best friends throwing things at each other like they were still seven years old.

--------

Ryou opened the door to his father's London flat. It was a small, cramped apartment with limited space, only big enough for Ryou's father himself to live inside. Ryou never really liked to live with his father, who hid almost everything about his personal life from his only remaining child.

"Father?"

Yaten Bakura wasn't home. Ryou sighed. He had actually been looking forward to seeing his father again after five years. Ever since he had moved to Japan, Ryou had found it increasingly difficult to see his father, who was often away on archaeological digs, or in London. A comforting hand rested on his shoulder.

"Maybe we should come back later," Seto said.

"Yeah, maybe," Ryou said quietly. "This is a pretty busy time at the university. He might be back later."

"Don't look so unhappy." Seto's hand reached over and gave him a hug around the shoulders. "We're here for another month or so, right? We have plenty of time to see your father."

"I was looking forward to introducing the two of you," Ryou murmured unhappily.

"We'll get the chance." Struck by an idea suddenly, Seto hugged the albino again. "Why don't you show me some of the collectables you have in here? I was looking forward to seeing your games."

"Sure, why not?" The other boy brightened almost instantly. "Come on, then, it's in the back."

Ryou went ahead, a light bounce in his step. The CEO smiled and shook his head at the other's ability to throw away sadness in an instant. He would never be like that, which was perhaps the reason why they had become fast friends. Ryou complemented him well. He was the better part of him.

"Come on, what are you waiting for?"

"Nothing much." Seto allowed himself to be tugged away by an overly bright Ryou, who wore a bright smile as he led the way to the back room.

"This is the only room in the apartment that I can actually use," the albino chirped. He opened the door. "It's too small to be a bedroom, as my father says, so I just keep the things I couldn't take to Japan in here.'

As soon as Seto saw the room, he knew that Ryou was indeed a game-lover. In his apartment in Domino, Japan, Ryou had had many board games, card games, computer games and miniatures in his 'game room'. But that was nothing compared to what he kept here.

In the centre of the room were four tables. The largest one held a game Seto knew well: Monster World. It was Ryou's favourite game and the only one that he could beat the CEO and number one gamer at. The table next to it was a chess set and the one next to that was Seto's professional game: Duel Monsters, or Magic & Wizards. He created technology for this game and that was what his company specialised in. It earned him millions a month.

The last table was Dungeon Dice Dragons, a game invented by one of their classmates, Ryuuji Otogi (A/N: for the dubbed-viewers, Duke Devlin). Seto scowled at the thought of the dark-haired, green-eyed teen. Ryuuji Otogi was one of the most popular males in their school, a pretty boy with a habit of flirting with anyone – male or female – who caught his interest.

And, to Seto's immense dislike, Ryou had happened to catch his interest. Not that the CEO could blame him. Ryou was one of those people who could walk into a room and then all heads would turn in awe. He knew, because he had been victim to that at one stage. Ryou walked past him to the Monster World table and Seto sighed inwardly. Sometimes he still was.

"This is amazing, Ryou," he noted, looking around at the numerous games displayed in shelves around the room. "I don't think I've seen this many games in one room."

"Nonsense, Seto," Ryou laughed. "The Kaiba Mansion has much more than this. Compared to your collection, this is but a drop in the ocean."

--------

After checking out the games, they went out for lunch. By this time, something had started nagging at the back of Seto's mind.

"Ryou, I need to ask you a question."

The albino looked up from his meal, blinking in confusion. Seto jabbed his lunch with his fork a tad too forcefully. Several carrots went flying. They both paid this no mind, as both were focused on what Seto had to say. The CEO swallowed and met Ryou's dark eyes.

"Your father – why doesn't he let you live with him?"

Ryou's face dropped and his eyes grew saddened. Immediately, Seto wished to take his words back. He hated to make the albino unhappy. Opening his mouth to make an apology, Seto found himself being cut off by Ryou.

"It's a long story. When I was six, my mother and my sister died in a car accident back in Tokyo. Since then, my father came back to England, where he was born, and took me with him. He worked late nights and didn't come home until I was asleep. It took me a while, but I figured that it was because I looked too much like my mother for him to bear so he stayed away. Finally, he moved me to Japan when I was eleven and he stayed in England. I've only really ever spoken to him face-to-face three times in the last five years."

"I'm sorry."

"There's nothing to be sorry about, Seto," he replied with a smile. It didn't quite reach his eyes. "I'm over it. It doesn't hurt as much as it used to."

But the fact that it had hurt him at all was enough to make Seto's blood boil. How could that man send his own, eleven-year-old son to Japan by himself for his own selfish reasons? From what Ryou had told him before, Seto had thought that Yaten Bakura was a good father despite the fact that he rarely came to see his son. But Ryou made it sound like the reason his father left was his fault.

"It's not right for you to live alone." Seto put down his fork and folded his arms. "When we go back – no, scrap that. I'm calling the servants and they're moving all your things to the mansion. You're going to move in with me."

"You don't have to do that, Seto," Ryou protested. "I'm perfectly fine living alone. It'll be too much of a bother to you, having me around the mansion."

Seto held up a hand to stop the flow of protests from the other teen. He had made up his mind and it was impossible to keep him from achieving what he wanted now. Ryou insisted he didn't have to help him out all through the meal, as Seto paid the bill and as they walked down the street. Finally, Seto couldn't take anymore and turned to face him. The albino stopped, surprised at the change in attitude from the CEO.

"S-Seto?"

The CEO led him around the corner, hand grasping his elbow firmly. When they had turned into a deserted side street, Seto pinned Ryou to the wall. The dark eyes widened in surprise.

"I'm taking care of you," Seto said firmly. "You're the best and closest friend I've ever had and I'm not going to see you live alone. I don't know what you think, but you are the most important person in the world to me. There will be no arguments, because I always get what I want. Understand?"

"Seto . . . you – you promise you won't regret it and that I won't bother you?"

"I promise."

Ryou's eyes filled. No one had ever treated him as well as Seto did now. It had been a long time since someone had shown such compassion towards him and he couldn't help but cry. Seto's determined expression softened considerably and he held the smaller teen quietly as he sobbed into his shirt.

"You're too nice to me, Seto," Ryou sniffled after a while. "For five years, all you've done is give. Everything you've done has benefited me, but I haven't done anything for you. I – I don't know if I should tell you this but . . ."

He pressed his lips to Seto's cheek in a chaste way, blushing. Seto blinked in surprise, holding a hand to the place where Ryou had just kissed. Did the other have those feelings towards him? Ryou leaned against the wall, looking downward shyly, a faint pink blush spreading across his cheeks.

"Ryou . . .?"

"When I'm with you, there's this warm feeling . . . it's better than how I felt when my mother and sister were still alive. I-I don't know if you feel the same or not, and this'll probably ruin our friendship, but I really do have feelings for you."

--------

"Is it time?"

"Not yet."

"When?"

"Three more days."

"Oh." A pause. "Are you sure they'll meet?"

"Yes."

--------

Remus sighed as he stared out the window of his room. The moon was almost at its fullest and soon he would have to begin his transformation. He wasn't looking forward to it at all. He grimaced. The transformation was painful and he hated it. Not to mention the fact that he lost all control of his mind when he was a werewolf.

"Hey, no sweat, Moony. We'll be there remember? Prongs and I'll keep your werewolf in check."

"If only it were that simple." Remus sighed again. Sirius watched him, a sad expression in his normally bright eyes. "The transformation hurts, even more than the duration of being a werewolf. At least I don't feel anything when I'm a werewolf. If I got to choose, I'd rather stay that ugly beast than go through the transformation process."

"Remus, we're here for you." Sirius clapped a hand on his friend's shoulder comfortingly. "Remember, we're friends and friends never ditch each other. James and I will never ditch you."

"Thanks, Sirius. But if we ever got found out – especially Professor Dumbledore . . . I don't want to get into trouble."

"I know you don't." Sirius grinned. "That's why Prongs and I are gonna take 'special care in concealing this fact. And we'll keep Wormtail from blabbing out anything. That silly twit would talk under pressure, I betcha."

"Don't be so unfair to him. Peter's a very nice person and he wouldn't talk."

"He's dodgy," Sirius said stubbornly. "If it weren't for the fact that he already knew so much about the three of us, I'd get rid of him for good."

"That's horrible Sirius!"

Remus reached out to hit Sirius over the head with a pillow playfully, only to have the other fling it back with his arm. That started a pillow fight as soon as James came out of the bathroom and joined them in the room. It continued on until Mrs Potter came in and told them to go to bed, sounding very much like Professor McGonagall back at Hogwarts.

Author's Notes:

I've decided that I like soccer, but I'm a real newbie at this sport, so I wanted to know whether you guys know anything about it. Things like teams that are good, any special players I should note and the general game rules and all. I've really started to like soccer . My favourite position is GK.

And I hoped that this chapter was good. I'm an impatient person and I really wanted Seto and Ryou to get together (come on, they've known each other for five years . . . and they're closer than normal best friends are anyway!). What should Seto say in reply to Ryou's feelings? I've made up my mind, but I want to know what you guys think!

Since this fic is going to be a Sirius/Remus, I need a way of getting them to like each other! Any ideas? I don't want anything too corny, or something that's too common. Something that I can write so that it makes people remember it. I'm picky . . . sorry about that ;

Anyway, could you guys please tell me more about soccer?
