A/N: Wow! Another new fic! A new adventure! Whooo! But, hold on, because I probably have to explain a lot of it. The first, and most important thing, this is written basically as though 'The Decline of Duel Monsters' (You'll know it when you get there) was trigged directly after Battle City, mainly because I haven't seen after that yet. (Yup, good ole' Britain is still in the Virtual World arc) I need to get cable… Anyhoo, this is going on the general assumption that in the beginning of the whole thing, Yugi, Seto, ect. were 15, Mokuba was 11, and Serenity was 12. (I always thought she was 13, but for the sake of convenience…) This fic is set four years after that. Aka, Yugi, Seto ect. are 19, Mokuba is 15 and Serenity is 16, for those of you who can't add up. Oh, and this is mainly based on the British school system, so Mokuba is in his final year of Secondary school, Serenity would've just started college, and yeah, the others would have been able to enrol at University at 18. If ya don't get it, tough nougies.

Finally, and most importantly, THE MILLEUM ITEMS ARE NO LONGER AROUND! Seeing as I actually know what happens to em, I see no reason for them to be included. Okay?

Now, this is just an intro chapter, so it's small and lame. But bear with me, things should get going next chapter!

Disclaimer: Teenage Mokie! What? Oh, I don't own.

One: One of those days…

Seto growled softly to himself and banged on the door again. Finally, his younger brother's head appeared.

"Yes?" He said innocently. And loudly.

"Turn it down!" Seto ordered.

"What?" Mokuba asked.

"I said turn it down!" Seto bellowed over the music that was now more then ever pouring out into the corridor and polluting his ears.

"Turn what down?" Mokuba grinned.

"That noise!"

"It's not noise! It's music!"

"It's loud and it's in my house. It's noise!"

"You just have no taste in music." Mokuba sniffed (loudly) but none the less, went and begrudgingly turned the stereo off.

"Thankyou." Seto said, miming hitting him over the head. "I surprised you don't kill yourself."

"Like you can talk…" Mokuba muttered. "How many times have you nearly killed yourself? I seem to remember Yugi telling me about someone who knew he was losing a duel and so stood on a castle wall above a 50-ft drop, the ocean, and sharp rocks, and threatened to-"

"You're going to be late for school." Seto growled threateningly, arms folded.

"You're going to be late for work!" Mokuba retorted, sticking out his tongue.

"Oh, grow up." Seto sighed. "Besides, I'm the boss, I'm never late. Now, go on, get out of here!"

"Fine." Mokuba said grudgingly, walking down the stairs. "See ya later, Seto."

"Yeah, bye."

A few seconds later, he heard his brother's exclamation as he saw the ocean that had apparently got bored of the beach, because it was now falling from the sky. Seto shrugged. Hey, Mokuba was the one who had insisted on not riding to school in the limo. Seto had just had to go with it.

He was sure he wasn't like this when he was fifteen.

Mokuba gritted his teeth. It was obviously going to be one of those days.

o-o-o-o-o-o-o-o

You may have noticed that Seto Kaiba seems to have 'lightened up' considerably in the last four years. Not many people care to speculate on why this is, and frankly don't give a monkey's, but for those who do, there is one generally accepted theory. And that is what 'experts' call The Decline of Duel Monsters.

As Yugi Moto won more and more matches, it became fairly obvious that no-one could beat him. Not even Seto Kaiba. And as soon as this became clear, duellists, even the most ambitious players, could see there was no point in competing in tournaments- It was obvious who the winner would eventually be, the outcome would be decided before the first players had drawn their hands. As a result, competitions stopped running- the 'serious' players had already forgotten about their dreams and aspirations to be the best, because it was unreachable. Motto was untouchable.

With no tournaments or opportunities to duel new people, even those who played for fun eventually became bored. I2's business began to fail, and a game that had previously run everything was forgotten.

Which had an understandable effect on those we all know the best.

Seto Kaiba, being Seto Kaiba, had seen it coming for years. So, while it was still a craze, he made his fortune and established Kaiba Corp. as a company by selling his Duel Disks and other related merchandise. Just before it crashed, he stopped production of aforementioned items, much to everyone's surprise. By the time the population was moving on to the next fad, Kaiba Corp. was establishing itself (and beating the crap out of all the other companies) in the field of AI. While the robots weren't independent or sentient yet by a long shot, they were certainly the most advanced.

Which made Seto a very rich man. Again.

Peguas, if he was honest, didn't particularly care about Duel Monsters going down the pan. He was retired anyway, and he had always known the day would inevitably come. The cards were no longer being produced, simply because they wouldn't sell. It was sad, yes, but at least his beloved monsters would live on to some extent in the hands of an aspiring business-man…

Whose name was Duke Devlin. In a move of desperation, and, or so it was rumoured, intelligence, to keep his game alive, DDM brought up I2 and hence owned all rights to Duel Monsters. Then, he had gradually bent or created rules for the dice game that allowed it to be incorporated into almost all types of gambling. DDM was now a favourite in casinos and arcades the world over. Perhaps not the most moral of decisions, but it certainly made him rich. Unfortunately, it also meant he was abroad a lot, which, though not bad in itself, meant that he had more or less lost contact with his friends, including…

Ryou Bakura, who had left for England some years ago, to go to college and then University. Last anyone had heard, he had taken a year out of Uni to go travelling with a friend of his. He had been excited at the prospect of travelling the world and seeing new places, countries like New Zealand, Australia, Peru, China and…

France, much like Mai Valentine, who had been accepted at what she called a 'fashion college' in France. Apparently, she was learning how to design all her own clothes and wasn't doing to badly at selling them either. Things had turned out pretty well for her, as they had for…

Joey Wheeler, who, on completing school had moved out of town to live with his mom and sister. This meant that Serenity would no longer be visiting Domino, unless Joey came back to, much to the chagrin of…

Tristan Taylor, who was still in Domino but had been pretty distant since Joey left. He had neglected University in favour of an apprenticeship at the local mechanic's, unlike…

Téa Gardener, to who Uni. had been a dream come true. She had left home and was now living on campus, taking a degree in both Literature and in Psychology, a class she shared with…

Yugi Moto, who, although taking courses at the University, had remained at the Game Shop to work there in his spare time. A feat he finally got paid for, I may add. Heralded four years ago as bringing new life to the flagging game of Duel Monsters, he was now almost always blamed for its downfall.

He was just too good.

As any animal instinctively knows, when an older generation is dying, the only choice is to bring in a new generation in the hope that the species will survive another decade.

Perhaps it was time for Duel Monsters to do the same.

Or perhaps it was already too late. Beyond the point of no return. A species that is extinct cannot be revived, despite those who have so painstakingly tried.

But surely, Yugi and the others should be the ones that know the best that some things buried under the sands of time are best left buried.

You never know what you may find.

o-o-o-o-o-o-o-o

Mokuba was tramping through the wet, already soaked through. And he had only just got down the to the street proper. He, as he so often did, cursed the architect that had built the place. Why on Earth would they need such a long drive-way! What, did people think they'd have a fifty foot long car?

"Hey!" Someone shouted. "Yoo-hoo! Mokie! Wait up!"

Mokuba gritted his teeth again and walked a little faster, pretending not to have heard. The voice was whiny and unmistakable. A fellow class mate of his, a very irritating girl who followed him around. A lot. Suddenly, he heard gales of laughter behind him and Mokuba gave a mixed sigh of relief and exasperation as he realised he'd been fooled again.

"Morning." He said wearily, as his friend, a girl named Risa who had an amazing infinity of being able to put on various voices and imitate people perfectly.

"The richest family in Domino and you still can't afford an umbrella." Was her greeting.

"You don't have one either." Mokuba pouted as they reached the bus stop- and just in time, as the bus was pulling up at that exact moment.

"Why does it always rain?" He asked miserably as they climbed on. "I'm soaked…"

"Well, so am I now!" Risa yelled back, as he shook the water out of his hair. This act earned him the second wack upside the head of the morning.

Oh yeah, it was defiantly one of those days.

o-o-o-o-o-o-o-o

A few hours and a little drier later, Mokuba rested his head against his locker door and sighed. It had been one of those days. He got yelled at in history, because the teacher didn't believe him when he that a stray dog had eaten his homework. The irony of it was that at break time, a dog that had got onto the grounds had eaten it. Then vomited it up all over his shoes, which was what had made him late to the class in the first place. His life had to be a sitcom, really. Otherwise things like that wouldn't happen.

Not to mention in gym class where the gym teacher deliberately tripped him up so he would screw up the vault. It wasn't fair. Mokuba was obviously the best in the class, and he wasn't boasting- it was true. The gym teacher just didn't like him. And as for getting his hair cut… Oh yeah, he was really going to get a crew cut. Yeah, then he'd look so much better.

Stupid evil gym teacher. If only he hadn't come out of that weird coma all those years ago… Long hair was apparently a sore subject for him. Who knew why?

By the time he'd been lectured by both the history teacher and the gym teacher during lunch break, it was nearly over. Which meant only the most crummy things were left. Rather squeamish by nature, he declined to have anything. He should really start bringing his own. But that meant either he'd have to get up even earlier to make it, or accept Seto's offer to do it for him.

Seto Kaiba can do a lot of things. Cooking is not one of them. Even his sandwiches could be disastrous.

And as for when he tried to cook meat… Was it any wonder Mokuba had been pretending to be a vegetarian ever since Seto fired their cook? Why did he fire the cook, you ask? He was worried a cook would poison them, naturally.

Plus he obviously didn't notice how bad his cooking tasted.

"Hello Mokuba…" Someone said softly in a tone they obviously thought seductive. Normally Mokuba would put up with and join in with Risa's horse play, but right now, for obvious reasons, he wasn't in the mood.

"I'm not falling for that again!" He said wearily, not turning around as he began to take his stuff from his locker so he could go home at last. "So just pack it in. I'm not in the mood for you right now. Or ever, actually."

He heard heavy footsteps as someone ran away sobbing. He turned around, already dreading what he would see. No, it wasn't Risa. This time, it really was that girl that kept following him. And he'd made her cry. Oops. He really should find out her name and apologise… but right now, he was just irritated. He hadn't said anything wrong! It was her own fault, for constantly annoying him.

He was just about to leave, when he heard someone coming up behind him. Evidently her crying had just been to get sympathy.

"Look!" He said harshly "I already said! I have no interest in you or your opinions, so just leave me alone and let me get on with my life in peace!"

"Excuse me? What did you say to me!"

"Oh nerts…" Mokuba mumbled, turning around, eyes closed. When he opened them, he saw his rather irritated head teacher.

One of those days…

o-o-o-o-o-o-o-o

The Game Shop's sign read closed, as Yugi hadn't bothered to open it yet. As all the prospective customers were in school, there wasn't much point. So, he was trying to get some of his coursework done. He was never gonna finish this essay…

Suddenly, the shop door opened, the small bell above it tinkling into the silence of the room.

"Sorry, we're closed…" Yugi muttered, trying to figure out what the question meant, not yet even attempting to figure out how to answer it.

"Oh well." The person sighed. "Maybe I'll come back later…Tell me, is the music shop still where it was before?"

Yugi looked up the second he recognised the voice.

"Huh! But you…"

A/N: Well, did ya like? I'm all excited because it's a new fic! Or that could be the pocky talking! Because I have finally acquired pocky! Do ya know how hard it is to get in this country? Well then! Anyhoo, face the wrath of my cliff-hanger! And I know it's a cliff-hanger, because Willowwind told me so and she knows all! Except who's in the Game Shop! But only two people and myself know! You all have to guess until chapter two! And that will be up next Saturday at the latest, if all goes to plan! So, R&R before I spontaneously combust and it would be a big explosion 'cause I'm full of sugar and sugar is energy so that means it BURNS! BURNNNNNNSSSSSS! MWHAHAHAHAHAHAHA….
