A/N: This story is not exactly a sequel to "Happy Guardian Day!" but does follow it in the timeline. I've had this basic idea for a while so I'm ready to finally get it out of my head and be able to work more on my crossover fic. I hope you all enjoy this Kaiba Brother multi-chapter and constructive criticism is much, much appreciated but pure insults is just wrong and I don't condone them. If you really don't have anything good or encouraging to say then don't even waste your time clicking the review button. I simply write these because I enjoy it, not to piss people off. So, I'm sorry if I am a rain on your parade but there are other things that you could be getting angry about, not over a story. Rant over, enjoy, and review if you like:)

Disclaimer: I do not own Yu-Gi-Oh!, its characters, or duel monster cards but I am making up the card that will be given for testing in this chapter. Other than that, Kazuki Takahashi owns it all!

Chapter 1: Unexpected Visitor and A New Card

XxXxXxXxXx

It was the final week of June but the beginning of the busiest time for gaming companies, especially for one of the most prestigious and advanced companies in the world, Kaiba Corporation. Being the heart of Domino City, for within the city belonged most of the world's best Duelists, Kaiba Corp. never missed a beat in producing the most advanced systems for duelists of all levels, from "beginner" all the way up to "pro". And with school out and people coming and going on vacation, it was the perfect time to finish up preparations for a new Duel Monster's Tournament.

It was nearing completion and the CEO of Kaiba Corp. was very pleased at the rate of production of a new duel disk for the new tournament's invited duelists, whom were ranked from "pundit" to "professional", and of course, "The King of Games". The tournament would be for all levels but these new duel disks would be much more realistic as the card's visual effects would be ten times more life-like than the duel disks used in "Battle City". It could be hazardous to beginners and that's why only the more experienced duelists were being "gifted" (that is to say, anyone participating must pay for them) these disks. Even the young teenage president himself was a little shaken up after conducting the first test on the prototype. He couldn't wait to put it into action with a real duelist but, unfortunately, he was under a contracting oath not to duel with the newest devices until what was being called the "Duels Around the Globe" tournament started. The contract was signed by the three gaming CEO's who created such a world-wide event: Seto Kaiba of Kaiba Corporation, Zigfried Von Schroeder of Schroeder Corporation, and the card-creating man himself, Maximillion Pegasus of Industrial Illusions.

It was nearing the end of a very productive day as the 18 year old CEO was finishing up signing reports and other documents that needed his signature. Most of the company had already gone home leaving him and his secretary behind. As long as she didn't disturb him he didn't care when she went home. He only cared about finishing these documents and getting home himself. He was determined to have everything caught up before he left for home. He had made a promise to a certain someone in his life to not stay up late working, and he was always a man of his word.

Buzz, buzz, buzz… his phone desk droned on until finally, the brown-haired, cobalt-eyed CEO pushed the intercom button.

"Mr. Kaiba?"

"You better have a good enough excuse for this, Ms. Takioshi." His tone of annoyance changed to anger in a heartbeat. "What is it?!"

"I'm sorry to disturb you, Sir, but you have a visitor." A visitor? He wasn't expecting anybody, especially this late in the day. Who on earth could it possibly be? While he pondered on who might be trespassing, his secretary continued.

"He is very persistent on seeing you, Sir. Says he won't leave until he has done so. Shall I send him in?" Hmm, there was a number of people who were persistent enough to have a private meeting with him but given that it is close to a big tournament starting in just a few short weeks, Kaiba narrowed the options down to two people, neither of which he would prefer to see in his building or anywhere on his properties; but such is the way of life when you have no choice but to partner up with a couple of rivaling companies.

"Yes, Ms. Takioshi, send him in and you can go home for the day."

"Yes, Sir, and thank you, Sir." With that, she hung up. A few seconds later, there was a knock at the big oak doors that stood as a barrier between the head official's office and the rest of his company. Kaiba laced his fingers together as he began tensing up in his leather chair. He was not going to enjoy this.

"Come in." The door clicked and opened slowly, the creaking being a nuisance like nails on a chalkboard. I knew it; of all the imbeciles to show up, it has to be him.

In the doorway was a tall, more older gentleman, with long, silver hair covering up the left side of his face. He was wearing a fancy red overcoat with four buttons in a "box" pattern on the front, red pants, and white dress shoes. Under his coat was a white, ruffled blouse with a black string tied into a bow at the base of his neck. His hazelnut eye twinkled and his smile was as irritating to Kaiba as ever.

"Hello, my dear Kaiba-boy, it's been too long since we last saw each other! I do hope you forgive me for not showing up to the opening meeting discussing the start of our "Duels Around the Globe" rally, but I had a matter of great importance and urgency come up. You know how it is." The man exclaimed very energetically in his almost British-sounding, yet American, accent. Kaiba said nothing, only continued to glare daggers at the "snake" standing before him.

The man just droned on without a care in the world. "Anyway, I am here because I have something to lend to you. But make no mistake, it is not a gift and I expect to have it back in due time. It is a new card just released by my company and I want you, Kaiba-boy, to be the one to test it before our tournament begins." He held out an envelope and a document for Kaiba to take. The blue-eyed teen took the document first and upon scanning the first line looked up, his eyebrow raised in question.

"A contract? What the hell for, Pegasus?"

His rival's smile grew even more, so much so you would think it consumed his entire face.

"I'm so glad you asked, Kaiba-boy! That there is a contract to ensure that I do get this card back. I wouldn't want to do dealings with a thief..."

"Look who's talking?" Kaiba interrupted. But Pegasus just ignored him and carried on.

"And by signing, which you will do, I will have ensured your co-operation. I would hate to have the courts involved but sometimes you have to be prepared."

Kaiba looked back down to the document laid out before him. Quickly, but smoothly, he grabbed his pen and signed the binding sheet of paper. He pushed the insignificant piece of wood back to Pegasus. It was just a card and he already had all that he needed. Pegasus could take this card with him to his own grave, for all Kaiba cared. It meant nothing to him.

Pegasus was observing every detail of Kaiba's behavior from the second he saw him from the doorway. He saw it all: Kaiba's tension, his "what the hell are you doing here" look, how quickly he signed without even reading the entire contract... It was going better than he expected. He picked up the contract and pushed the envelope to Kaiba.

"Here you go and do take great care of this card. It is a one of a kind, and I will send Croquet to fetch for it when I'm ready to have it back." He casually stood up, turned around, and walked back to the doorway. But as soon as he reached the still open doorway, he stopped. He turned around slightly so that his right eye, the only visible eye, could look at the young business partner across the way. Kaiba was reaching for his letter opener to dig into the envelope, not realizing Pegasus was still in the office.

"You might want to wait to open that after I've left your building, Kaiba-boy." Kaiba stops abruptly and looks back at the doorway but Pegasus was already walking towards the elevator.

What did he mean by that? He mulled over in his head the options of what really could be in the envelope. What kind of card would Pegasus give to him and expect him to wait until he was gone to see what said card was?

The CEO stood up from his chair and looked out of his window. Pegasus could be seen walking down the steps towards a red, fancy vehicle with a man clad in a black suit with short, wavy blue-green hair holding the door open for his employer. He followed suit by climbing in the driver's seat and starting the engine. As soon as the car went down the street and out of view, Kaiba turned back towards the envelope on his desk.

"What is that lunatic up to this time?" He asked no one in particular. He grabbed the letter opener and opened the small envelope and pulled out its content. It was indeed a duel monsters card from the back but when the young president turned it over, his blood froze.

It was a trap card, the title reading "Revenge of the Blue-eyes". The picture depicted a stream of blue and white light striking down a human with a duel disk on their arm. The inscription below explained its effect: Activate this card when a "Blue-eyes White Dragon" that you control is destroyed in battle. Half of that "Blue-eyes White Dragon"'s attack is then dealt to your opponent's life points as a direct attack. This does NOT negate any equip spell cards that was given to the "Blue-eyes White Dragon".

Kaiba's eyes narrowed in complete anger. He now held a very useful card that could easily help him to defeat even the King of Games and his lifelong dueling rival, Yugi Mutou. But thanks to the contract he just signed, he would probably never get the chance to use this card on Yugi before Pegasus reclaims it. His other fist clenched and he cried out with all the strength and fury he could muster.

"Pegasus!"

In a red vehicle driving down the freeway, there sat man with silver hair covering half his face sitting in the back seat. His already smiling mouth opened and he began laughing like a crazed maniac.

A/N: Alright, so the next chapter will start bringing out the plot but I needed a good transition chapter for this next one. I should have the next chapter posted either tonight or sometime tomorrow. Enjoy!
