Domino, Japan

800 hours, GMT +9

A raven-haired teen looked at his brother. They were sitting in the small house the two now owned. Kaiba Mokuba was now getting ready to head to Domino High, where he was a senior, and top of his class. Seto, however, was sitting on his couch, from which he had barely moved for almost a week. Soon, it would be time for him to go stagger down to the liquor shop and buy more booze, which now served for most of his meals. What little he did eat was all but forced down his throat by Mokuba, who did all the cooking and cleaning, and even had a job after school. It would have been against the rules for most students, but Mokuba had special permission, due to his circumstances.

"Are you finally going to look for a job today, brother?"

Kaiba Seto finally moved, his arm swung up and his head went back as he downed another bottle of booze. This was his only response. It was becoming more and more common. Mokuba shook his head, turning. He would have to go on being the bread winner a while longer.

Seto sensed his brother leave. His brother, who had once idol-worshiped him. Not that it was bad that a 17 year old boy no longer believed that his brother was superman, but now he had to seem him like this. A splash of liquid hit Seto. It had not fallen from his now-empty bottle, but rather from his already bloodshot eye. Proud Kaiba Seto, who all had called Kaiba-sama (at least, they did if they knew what was good for them) was crying, as he now did regularly.

Domino Japan used to be a simple suburb of Tokyo, where the majority of the town supported the great military industrial corporation, Kaiba Corp. Run by the bad – no, not merely bad, but evil – Kaiba Gozaburo who raised the orphans Seto and Mokuba to take over the corporation one day, and run it in their – no, his, Mokuba was only there because Seto had insisted on it before he go with him – adoptive father's stead. The problem was, the extensive training had been abusive, if that word could even apply to the level of suffering Seto had been forced to go through. Jokes on him though: as a ninth-grade middle schooler, Seto co-ordinated a hostile takeover of Kaiba Corp, driving his abuser to suicide, jumping out of a skyscraper window during a board meeting, laughing all the way.

Seto changed the direction of the company immediately, turning them from a creator of expensive killing machines for Japanese government purchase only into a designer of games and game related products. While their most famous products had been incredibly expensive, especially at first – Seto would later laugh on finding whole rooms dedicated to holographics that he now sold wristwatches to create for a mere 5000 yen – most of the products were available to every child on the streets. This, along with a competitor of his, Devlin games, had turned Domino from a one-company suburb of Tokyo into the gaming capital in the world.

It didn't help that Yuugi Motou resided there. Yuugi was national and international champion of several games, including Go, Poker, Chess, and more. In most of these Seto himself was second, many times having lost his title to Yuugi. Yuugi, however, decided not to continue professionally gaming, following his 'real passion', Egyptology. Seto had scoffed at the time, but now....

But all that had ended now. He was no longer the head of Kaiba Corp. If it wasn't for his little brother, Seto would have done exactly what his adopted father did. Sometimes he wondered if it wouldn't be better for the kid. However, he forced himself to stop thinking like that.

Seto considered hoisting himself up on the couch and going out for a walk. It was something he rarely did. When he did, he found himself facing his technology infused with magic on every street corner. It was something he couldn't stand.

Magic. Seto sneered. He had made so much fun of his rival and his friend for their hobby of dabbling in the occult. Admittedly, that was more the case for Yuugi, Yuugi's friend Ryou lived the occult. Now, however, it looked like they were correct. Wizards had shown themselves. They had taken over Egypt, they had taken over everything, even his -.... He stopped there. Mustn't go down that path. Death and Destruction lived that way.

So, Seto decided to stay put. He had a few more bottles anyway. He picked one up, about to take a swig.

Knock.

Seto almost dropped the bottle he was opening. What on earth? It had almost sounded like a knock on his door. But that couldn't have been. He hadn't been visited since he lost Kaiba Corp. Maybe it was Mokuba's boss? Heaven knew why he took that job, the sale of the mansion had given them enough money to buy this house and live modestly for years. No, that didn't make sense, the boy starred at work, just like he did at anything else. It must just have been Seto's drunken imagination.

Knock.

He couldn't ignore it this time. There was definitely someone knocking on his door. Seto peeled himself off the couch and stumbled to the door. "Hello?"

A young blond man stood there, not much older than his brother. Early twenties maybe. He spoke with an accent. British, definitely. English, maybe Welsh. No, English.

"Hello, Mr. Kaiba." The young man's nose wrinkled. "My, but you do smell." A small wooden stick pointed at Seto, who recognized it immediately. "Hey, what do you think-" he started to slur, but was interrupted. "Sobrieo!"

Immediately, Seto felt the results of the spell. The drunken stupor that he had been cultivating for months now left, leaving a sober Kaiba Seto in it's wake. Not even a hangover remained.

The young man stepped into the Kaibas' small living room. "Now, this just won't do at all." He swept his wand – that 's what that stick was, a wand – across the room. Dirt disappeared, taking the empty cans and bottles along with it. What remained flew into it's proper place. The blond wizard stepped in and sat on the now-clean recliner. "Aren't you going to sit?"

Now thoroughly confused, Seto came and set on his couch. No sooner had he sat down but the wand was out again, and between them bearing a tray set with tea for two.

"I know you Japanese are almost as fond of a good tea as we are, but considering the state of your house just a few minutes ago, I doubt that I would find much here. Besides, I never quite got a taste for the green stuff your country seems so fond of. I much prefer a good Earl Grey myself. So I took the liberty. I do hope you don't mind?"

Seto shook his head, still stunned. "I think Mokuba does have some tea in the kitchen, but it is green."

"Good. Now, I believe I should introduce myself. After all, I do have you at a disadvantage. My name is Scorpius Malfoy, and, as you may have already guessed, I am a wizard. I have a business proposition for you."

"I'm sorry, Mr. Malfoy, but I no longer have a business, and I am not used to dealing with magical folk. So, if you don't mind..."

"Ah, but Mr. Kaiba, you certainly didn't think I had not heard of the takeover of the Kaiba Corporation? I am not that behind the times. No, I am offering you a chance at an economic revenge."

"I'm afraid that I don't understand."

"Mr. Kaiba, I'm offering you a chance to get back into the business, and drive the man who took your company over back to his own country."

The thoughts flashed through Seto's mind at a million thoughts a minute. Take that red-headed asshole on? There was little he wouldn't do for the chance. He remembered when he got the news. A board meeting took place, and a red headed stranger walked in.

"Who the fuck is this?" Kaiba-sama's rudeness was famous. So was his genius. It balanced out. Besides, he had been in a foul mood since the announcement of magic's existence.

The stranger spoke with an Irish accent. "My name is George Weasley, CEO of Weasley's Wizard Wheezes. And now majority shareholder of Kaiba Corp. Nice to meet you, Mr. Kaiba."

The beginnings of fear crept into Kaiba's face. "What do you intend to do?"

George Weasley turned toward the table of men. "WWW, Inc. has offered to buy all shares of Kaiba Corp. at market price. If Kaiba Corp agrees to this at a majority vote, the Kaiba Corporation will become part of the WWW empire. I now bring the matter up to vote."

The vote had gone round the table. A few of the executives voted yes, but most of them had voted no, as had Seto himself. However, now the vote now moved to the wizard next to him. "I vote yes. Tallying up the votes, I believe you will find that with my share of the stock, sixty percent of the company is voting for this. Kaiba Corp is now owned by Weasley's Wizard Wheezes, Incorporated. As my first matter of business as the new owner, you are all fired. Thank you."

Scorpius watched as the former business man shook in reaction to his words. Obviously, it had gotten to him. A smirk reached his lips. Yes, this would go his way. Soon, his soon-to-be partner calmed.

"Alright, state your proposition."

The sun was now well gone, and Mokuba was just now getting home. He dreaded going home and finding his brother on the couch. Now, after a long day both at school and at work, he was going to have to do the rudimentary cooking and cleaning that he had time for.

The last thing Mokuba expected to find as he opened the door was a light, besides possibly that of a television. No, strike that, the last thing he expected to find were the smells, that were bombarding his senses. "Did my brother get pizza?"

Opening the door turned out to be even more of a shock to the younger Kaiba. There his brother sat, on the couch. However, no bottles were anywhere, instead, two glasses of what appeared to be water sat on a table between the couch and the recliner. On the recliner sat a blond man that appeared to be in his early twenties, and not too far away from them was a drafting table and two chairs, none of which Mokuba had seen before. It appeared that the two had taken a break from planning on something to eat some of the pizza that sat in between them. Mokuba had to pinch himself to be sure he hadn't fallen asleep at work and started dreaming.

At the sound of Mokuba shutting the door behind him, both of the men turned to the door. Seto's face lit up in a way that it hadn't in so long. Mokuba felt tears rush to his eyes.

"Hello, Mokuba." Mokuba felt himself become enveloped by his brothers arms, as they shared an embrace. This sort of show of affection had been rare even before the corporate takeover of Kaiba Corp, and to have it now was an astounding thing. As the embrace broke, one of Seto's arms remained draped over his brother's shoulders, as he turned to face the now-standing blond man.

"Mokuba, this is Scorpius Malfoy, a Wizard. He's going to be helping me in our new business venture."

Mokuba stepped forward and bowed to the stranger, who seemed bemused by this cultural quirk, but returned the gesture before offering his hand to Mokuba to shake.

Mokuba took the man's hand and shook it in the Western-style greeting that he had been taught. "Thank you so much, Mr. Malfoy, for helping my brother."

"Please, Mokuba, call me Scorpius. I do not much care for the name Malfoy, it still has bad connotations in this world. My Grandfather tainted the once-proud name, and forced my father to do the same. Now, your brother and I can work together. The names of Malfoy and Kaiba will once again be names that we can be proud of."

"That's right," Kaiba interjected. "Blue Eyes Enterprises will clear the names of us all. Scorpius here has helped me to understand that there's a fundamental flaw in Weasley's business plan."

"Yes," Scorpius agreed. "Weasley's Wizarding Wheezes is one of the top innovators of magical products. They are doing some rather interesting innovation with Kaiba Corp products. However, they are doing no more innovation with the muggle side of things. That is, the mechanics of it. I believe that by combining magical and muggle invention, we can give ourselves at least a final chance."

Seto nodded. "Mokuba, I'd like you to quit your job. I'm going to invest all the money I got from the sale of our home, items, and Kaiba Corp stock into Blue Eyes. I'd like for you to come and work for us. We'll double your wages, and hire a maid for the house. Not a permanent one, mind, but someone to come in once a week or so and clean. We have plenty of money. That damn Weasley is never gonna know what hit 'im."

Thank you for reading the first chapter of this rather unusual crossover. This fic has a sister, Harry Potter and the Egyptian Menace, please check it out. In that one, you will find the Yuugiou characters in the potterverse. It focuses much more on the wizarding war taking place in Egypt. In it, you will find details on the wizarding takeover of Egypt and of the lifting of the veil, both mentioned in this fic. Please note that anything that happens here will be considered cannon there, and vice-versa.
