Expect the Unexpected

Prologue - Wish

Vongola HQ, Italy~

Chocolate brown eyes fluttered open. Stretching a little, the lone man groggily blinked the last bit of sleep away.

He had fallen asleep again, hadn't he? Despite all the caffeine he had tried to pour into his over-worn system. "It must be very late now." He thought dryly; looking at the twinkling stars outside the large window, a small sigh escaped his lips.

At the age of twenty-five, it seemed that life had to be perfect for the young man. Things had changed so much over those ten long years. Sawada 'Tsuna' Tsunayoshi was no longer that little shrimp, frightened and weak who needed to be protected. No, he had become a rather charming and clever young man. Yep. With somewhat soft features, milky white skin screaming sweet!, and a brilliant smile oh-so-ever-present on those rosy lips, Tsuna was very much adored by both men and women all around the world, or at least his world. And the fact that, he was the Tenth Vongola boss – The most powerful Famiglia of all time – which meant, everything for his every whims, didn't help much. Indeed, there was surely no reason for him to feel so…miserable at the present.

Or not.

Wearily, his gaze landed on the stacks of paper mountain-ing on the large mahogany desk – hellish loads of paperwork eating away his sanity day in and out – he sighed tiredly.

Oh gods, were there to be anything, anything at all aside from his everyday duty, he would still gladly be doing it; because, as he once swore long time ago, there would be nothing that could even beat the boredom brought by the punishment of Satan himself upon humanity, more specifically, him – namely paperwork.

That explained why, the young boss of Vongola was pretty much desperate now. He was bored out of his wits. And that just worsened each passing day.

It's not that he had to fight the boring work all by himself. There were helps every now and then offered by his over-enthusiastic right hand man, or even some generous attempts to help by his cheerful sword-man – keyword attempts. No, they really meant to help, it's just, he couldn't just throw his responsibility to the others' faces and be done with it, right? No, he simply didn't have the heart to do so…

Scratch that.

Truth was, yes, they really meant to help, but, last time he checked, everything would eventually either be blown off, destroyed, or tattered, scattered everywhere if ever those two presented in a same room. Despite his full effort to beg them to 'please, just please stop fighting and leave him and his office in one piece!', the two would never simply let go. Hayato-kun and Takeshi-kun, why did they have to keep acting that way all the time? Wasn't there something between the two? At the thought of his thick-headed guardians, he couldn't help but sighed again. "Oh, I just can't understand."

Shaking his head lightly to clear the unpleasant thoughts, his mind drifted over to the other guardians. Where were they again? Oh yes, Kyoya-kun had probably finished his mission in England by now, and was heading home. Ryohei-niisan must be somewhere around America gathering information. Lambo-chan, well, must be blissfully asleep now. Mukuro-san, he was as always nowhere to be found. It's not that surprising really. After gaining freedom from that despicable of a prison roundly five years ago, the mist guardian was finally able to do anything he pleased. As long as, as the initial terms stated, he didn't bring any harm to the Famiglia.

Now where was his dear Tutor? He didn't hear anything from him since…ah yes, he mentally slapped himself, how on Earth could he even dared to forget? Reborn was currently on a training trip, with him! Resisting the urge to slam his head against the table, he guiltily thought of his so-called twin.

Almost five years had passed since that fateful day, where he realized there had been two personalities coexisting in his body, two opposite personalities, mind you. And guess what, they had soon after come to excitedly announce a brand-new project, something about 'double the strength and flexibility of Vongola Decimo' by…creating a clone of his with the other personality, the fiercer of the two. That way, as they had dubbed it, one could go all out battling alongside their guardians, the other would, well, stay in their office at the HQ, doing paperwork and discussing strategies. That was more than enough a motivation for them to put forth their mind into freeing Mukuro, persuading Byakuran (the one of this dimension, thank you very much), even threatening Verde (don't ask), and coaxing Shoichi and Spanner into working overnight over three stressing years.

The outcome had been more than successful. There he had stood, proud and aloof, without a care in the world. Smiling a little, Tsuna remembered those sharp amber eyes peering through his very soul slowly turning soft as if they recognized him as their owner's other haft. And with a bright smile of himself, they had become as close as 'twins' could possibly be…maybe even something more. At that, a light blush tinted his cheeks.

"Tsunayoshi…" He whispered quietly, "Be safe."

Wait! Where the hell did it come from? And what was he thinking anyway! He obviously was safe now! It's just a training trip after all. With Reborn no less. Did Reborn ever let anything happen to them? "Since when have you become such cheesy idiot hm." Blushing furiously, he took a deep breath to calm himself.

But, but, it was a bit lonely here, wasn't it? He rarely had time for his friends nowadays, or any activities at all…Only damned paperwork. Grimacing at the sight of the seemingly endless whiteness right before his eyes, he sighed for the umpteenth time that night.

Maybe, just maybe, for the sake of his mental health, he needed a very simple miracle, like now.

A vacation would help. Maybe a trip to some faraway place? Just to change the atmosphere, if anything…

Yep, a vacation with everyone sounded nice indeed. Some extra fun, like an adventure, would definitely be sweet too. Without paperwork no less, ha!

Suddenly he had the urge to be again a naive little boy, like, do something a bit silly…hm.

Sighing in defeat, he gently crossed his fingers, "I wish…"

~X~

Domino, Japan~

"Thank you for the game."

A deep bow.

"Thank you for the game."

A sigh.

Shaking his head distractedly, Mutou Yuugi began to collect the white stones on the board, before feeling his opponent do the same with the black ones.

For almost three years, he has plunged into the world of Go. Blindly find something, anything to sooth his desperate boredom. To once again feel the excitement of challenge.

But who could blame him?

They had all parted way. The Ishtars had returned to Egypt right after the Battle City to continue their duty; Ryou to England, after high-school, to begin the university. Even Seto had left to become a full-fledged businessman. And grandpa, he had left him, to a faraway place…

He himself had chosen to stay in this small town, as fond of it as he was. Along with his Yami, he has always held firm the crown, as Yugi-oh – the King of Games. Duel Monster had been, was his forte. His favorite. However, after five years trying to find a worthy opponent – who, as Yami had once defined, could even last fifteen minutes against him, he had given up on dueling.

He had tried Chess, an intellectual and relatively hard game.

Yami, Seto had been his only opponents.

But, wasn't Yami and Seto always have been his rivals here?

He had then tried Shougi, a different form of Chess.

The result had been the same.

So, he had then sound for Go.

It had been fun. There had been so many strong players. All around the world, they had come to him. Yeah, he had had so much fun…

For two years.

Oh, how could being a fast learner now annoy him that much, he absolutely had no idea.

He had finally mastered it, the art of Go.

That, led to his last painful year.

And that match just now…

He was having a wonderful dream, something involving his Yami, ice cream, and fresh strawberry. The bed cozy and extremely warm – he was contented in his Yami's embrace.

Then it just had to happen.

Something, someone had banged the door agonizingly loudly and shouted Ra-knows-what in the ungodly hour of two am, demanding they open the door immediately.

Yami had been furious.

Yuugi, well, the once shy little Yuugi, had tried his best to restrain his Yami and his murderous self, to oh-so-please listen to what the daring soul had to say.

A young man, in his mid-twenties, had insisted on playing against him. A match of Go, that's all he had asked for.

And who was Yuugi to turn down such a plea?

He had hoped, hadn't he, to find some rival…even in Go.

So, ignoring the tiny complaint in a corner of his mind and the almost tangible killing intent surrounding his Yami, Yuugi had set the Board.

The young man, though had some talent, as many insane Game's believers before, had been crushed only haft an hour later. Without mercy. Yuugi was not very soft while playing after all.

"It's…ridiculous…" He muttered, eyebrows furrowing.

A soft click tugged his attention away from the goban. Oh, it was just Yami closing the door.

Yami, totally cooled down by now, settled next to him on the floor, nuzzling his hair affectionately.

"Why seem so sad, Aibou?" He asked, concerned.

"Not really, just, isn't it too easy a win?" A sigh. "I mean, Yami, don't you feel a little too boring here? Everything always is the same. We always do the same things every day. I…Always play the same game. Always gain the same result…"

"Oh, Aibou. I know…I know–"

"No, Yami, you don't. I want something new, Yami! I need it! I miss it. I miss the old day, when we were all fighting together. And I worry about Jou! After that fight with Seto, he had left to Ra-knows-where and I haven't heard anything about him yet. Yami, I miss everyone so much, you know, so much…that I'm feeling so…I don't know…Yami…It's driving me nut…" He trailed off, voice trembling, crystal small tears running down pale cheeks.

Like the straw that broke the camel's back, Mutou Yuugi finally broke down.

His Darkness said nothing. He just sat there, hugging his beloved Light lovingly, and kissed the tears away; all the while murmuring sweet soothing words.

Clutching his Dark like a line-life that he really was, Yuugi sobbed uncontrollably, "Y-Yami, I…I wish…"

~X~

Funny how neither the King, nor the Boss knew that, right then and there, a soft light was glowing faintly from their precious items.
