My first fanfic here! Kind of excited and nervous about it. This is mostly a crossover between No Game No Life and some (if not all) Yu-Gi-Oh anime versions, since I've always thought it would be niteresting to know what would happen if both those worlds collide...

If the revies are good, I'll keep posting, otherwise, thanks for reading it!


Somehow, for some reason, they are all here. Every great character ever reckoned to be outstanding in their own time is here. Albeit they all come from different worlds, different times, different realities, they are all gathered together in the same city. The place is overfilled with a large quantity of people, extraordinary people, who desires to explore this world strange to them.

Even thought this phenomen began only a month ago, many interractions have already been hold between this masses and townfolk. But not only that: it seems that information trading between persons from different dimension, not specially ours, have been increasing by the time. Could it be that, whoever or whatever brought them here, have predicted this behavior? Is it possible that a greater plan upon these worlds gathering together are the means for something even bigger than what we are already witnessing?


Noboru Gongenzaka was sitting meditating on the floor, at the balcony of the hotel room he and his friend Yuya Sakaki rented for his stay in that world. Lately, with all the mayhem and chaos brought by the sudden appearance of many dimensional visitors, he had little to no time to be with himself. He even tried the hotel's roof, but there was always a bunch of flying creatures that blocked his concentration. Last night, for example, he was interrupted by some flying people fighting each other. But right now, he was enjoying the bright midday sun.

-Again with the meditating, Gongenzaka? -Yuya asked, who just came out from the bathroom. -I know there isn't too much time for that anymore, but how about going out for a bit?

-I'd rather stay here, if I may -he answered without opening his eyes. -I appreciate your invitation, but I want to clear my thoughts before going out.

-Clear your thoughts? -Yuya repeated perplexed, while putting his googles on. -Well, if you want. I'll go see Yuzu right now. If you want to see us, we'll be at the caf we went yesterday, okay? See ya.

Even after Yuya left, he couldn't feel distressed. Several days they have been in that world new to them, and no answers about they arrival had been shown. Nor even the visitors knew why they were here, not even a clue: they just appeared. However, this wasn't what worried him the most...
Ever since he arrived there, he had been feeling like something was missing, like something was out of synchro. Was it his Dueling? He had been working hard on perfectioning it to the point none of the opponents who presented themselves in Gongenzaka Dojo could have defeated him. Besides, he was in pair with the elite duelist, that included duelists from other times and dimensions. Was it his friends? No way, Yuya and Yuzu hadn't left his side since their arrival. Not to mention, they had been making new companions and friends after that, several duelists among them. Maybe there was something he had to do. The problem was simple: what was it? Something about people from other worlds, probably. But who? And why? There were so much amazing people with special abilities, but why did he felt some of them would need his help?
After fifteen minutes of struggling against himslef, he punched the wall next to him out of frustration, and the impact was such he left a hole in it.

-Hey! Who was it? -The occupant of the room behind the wall roared. His voice was deep and, apparently, raging.

-So-Sorry, sir!


-Ruca! Come see this!

-What is it now, Rua? You've been impressed by everything today...

-No! This is different!

The twins were sitting on a bench in the park. The whole day was just Rua being amazed about everything he saw and calling out her sister about it. Although she loved him, she was starting to get sick of him.

-Look, Ruca! I've been browsing in my Duel Disk, and it seems every Duelist in the town is listed here.

-Wow, really? Even those out of our dimension?

-Yeah, look! -He then passed his Duel Disk to Ruca.

The screen was showing a picture of every duelist and a couple of numbers next to it, including number of battles, wins, loses and all. Apparently, there was also a ranking.

-Amazing! Who do you think created this program?

-I don't know, but it's awesome! -He quickly replied. -Look: they are all ranked upon the Duels they have had in the town since our arrival. I'll show you: it here says I'm #185!

-It also say there are 200 Duelists here...

-Whatever! And you are #116. You're almost over the top half!

-Hehe, thanks I guess...

-Well, it's only a matter of time, since we only had like 30 duels so far. Give it some time and we'll be the best!

-I don't know... -She doubted. -So anyway, who is the top one?

-I'd bet it's Yusei, or maybe Yugi Motou. I heard he is the...

Rua couldn't finish that sentence. The moment he found the #1 Duelist, his face seemed to become paralayze out of fear.

-What is it, Rua? Something wrong?

-The... The... The #1 Duelist... -He had a really bad time talking.

-Who is it?

He frightenedly showed her his Duel Disk, only to show a blank image with no name and data. As soon as she saw the numbers, he understood why his brother acted so strangely.

*BLANK*
WINS: 16.253 LOSES: 0 DRAWS: 0

-16.253 wins and no loses?! -She exclaimed scared. -Who could achive so much in just one month?!

-I-I don't know, the name is in blank...


Yuzu and Yuya finished having lunch and left the caf . Although the last days were kind of troublesome and busy, right now the street seemed quite and peaceful.

-Well, I guess after so much time being here, people would actually get tired of us visitors, right? -She was thinking out loud while walking along with his friend.

-I guess so. But I still wonder what is it with Gongenzaka -He said with his look down, still thinking since he had left the hotel. -Since we got here, he's been acting weird...

-Give it a rest, Yuya. I'm sure he'll work it out somehow.

-Yeah, but...

-Yuya, wait! Look!

They both stopped, as Yuya also found what Yuzu did: a small girl with extremely white and long hair was laying asleep on a bench of the street, using a bag as a pillow. Aparrently, that girl was alone, since no store was opened nearby, due to it being Sunday.

-Yuya, do you think she's lost?

-I don't know, but we can't just leave her like that, something could happen to her...

-You're right. C'mon, let's wake her up.

When they got where the little girl were, they were stunned by the whiteness of her hair, the cuteness of her face... and the simple fact she was all alone in plain midday. She couldn'tnbe more than 12 years old...

-Hey, wake up... -Yuya started shaking her. -Wake up, it's not safe to be alone...

Slowly, the girl started waking up. At first, she groaned a little, but then she opened her eyes. She seemed to be confused, specially because the first thing she saw was a couple of strangers looking at her...

-Don't worry -started Yuzu-. We won't hurt you, we just wanna know if...

But the girls started to cry.

Both of them didn't know what to do. She suddenly sat up and hugged her knees in an effort to be safer. She was almost silent, but you could simply tell she was death of fear, as her eyes were more than wet and she was shivering.

-Nii... Nii -She started mumbling-. Nii, please come. Don't leave me alone...

-D-Don't worry! -Yuya panicked as he didn't expect that reaction, neither did Yuzu-. We'll find your brother! Everything's okay!

-Nii... Nii...

-H-He's right! Your brother cannot be far from here, right? -Yuzu tried to calm her down by placing her hand on the girls shoulder, but before she could, the latter cried even louder.

-What now, Yuzu?

-As if I know! What if...?

-Master, please don't cry.

Both the teenagers were startled by that sudden voice behind them. But not as startled as when they turned around and saw who was it.

An angel, or at least that's what they thought, was floating gracely right behind them. She was bearly wearing clothes and her magnificiently giant wings spreaded at her sides. Although she was wearing a sweet and tender smile, something in her eyes told them she wasn't such a kind creature.

-Master, please don't cry -She gently repeated while passing through Yuya and Yuzu, not paying much attention to neither of them. She then stopped right in front of the little girl-. There is nothing to worry about...

-Ji-Jibril... -It seemed like she recovered her senses, since she stopped crying, altough she was still sobbing.

-Your brother had to depart while you were asleep. I'm sorry I didn't wake you up, but I had to make sure first there was no one in sight to threaten you. His departure was just a couple minutes ago. He left along with Dola-chan.

-Really?

-Yes, Master.

-Ok, then -She then cleared her tears with his sleeve and stood up. Surprisingly for Yuya, she took a more serious face, nothing like the saddened girl who had been crying on the bench just a minute ago. -You two -She looked at Yuya and Yuzu-... I'm sorry for that. I overreacted after I slept, that's all.

-No problem, I guess... -Yuzu answered doubtfully, still trying to fit this weird scene into his head.

-Just who are you anyways? -Yuya asked, both perplexed and anxious.

-I'm Shiro. -The girl said firmly-. And she is Jibril -The angel waved them happilly.

-Nice to meet you. I'm Yuya Sakaki.

-I'm Yuzu Hiragi. Nice to meet you, Shiro-chan. -Yuzu tried to be polite to her.

-Duel me -Shiro instantly confronted Yuya.

-Wh-What? Right now?

-Yes. I heard your name, and I know you are a Duelist. I'm a Duelist myself, but not as reckoned as you are...

-Well, thanks for the compliment... -Yuya answered with a bit of shame.

-Can you Duel me, please? -While saying so, Shiro stared at him with her beautiful eyes wide open. Upon seeing them, Yuya couldn't resist but to say...

-Well... I guess one Duel would be okay...

-Can we bet something?

-What kind of bet? -Yuzu was intrigued.

-If you win, I'll give you one card of mine, a very rare one.

-Sorry, but I don't like Ante Duels...

-You don't have to wager a card. If I win, I want you to do me a favor...

-A favour? What is it?

-Well, I don't know where my brother is, and I would like some help to find him.

-So, you want me to help you find your brother?

Shiro just answered by a shameful look to the floor, not saying a single word. Just by seeing this, Yuya felt really bad for her.

-You know, you don't have to bet for that. I can help you without Dueling about it...

-But I want to Duel you...

-Okay... -Yuya finally replied, convinced that nothing wrong could happen-. I'll take the bet...

-Really? -Shiro asked a bit happier. Jibril laughed a little bit-. Can you swear to me by the Pledges?

-Pledges? What Pledges?

-They're some rules Nii and I follow when we play. It's a way we use to play fairly. Jibril, can you show them, please?

Both Yuya and Yuzu were impressed that the angel happily materialized a pergamine out of nowhere with ten rules written on it. But then again, she was an angel after all...

After reading the Pledges, Yuya seemed confused.

-What weird rules... But okay, I don't see nothing wrong with them. We'll Duel with the Pledges.

-Okay!

Soon, both Yuya and Shiro were facing each other with a distance of ten meters between them, both of them holding their Duel Disks. Yuzu and Jibril, meanwhile, were sitting on a bench in front of them.

Then, the Duel began with both declaring:

-ASCHENTE! DUEL!

-First turn is mine! -Yuya exclaimed while pulling two cards from his hand-. With Scale 1's Stargazer Magician and Scale 8's Timegazer Magician, I adjust the Pendulum Scale!

Suddenly, two vertical columns of light formed in both his sides, with each Magician inside of them. Then, a giant Pendulum was swaying around between them.

-With this, I can Special Summon monsters from Level 2 to 7 simultaneously! Sway around, pendulum of my soul! Draw an arc of light in the ether! Pendulum Summon! Now appear, my servant monsters!

After declaring this, he Summons Performapal Drumming Kong (Level 5, ATK 1600), Performapal Silver Claw (Level 4, ATK 1800) and Odd-Eyes Pendulum Dragon (Level 7, ATK 2500).

-Amazing! -Yuzu shouted out-. A Pendulum Summon in his first turn! Awesome, Yuya!

-How do you like my Entertainment Duel, Shiro?

-Not bad -Although she said that, she wasn't even smiling.

"What a strange girl", Yuya thought. Even so, he ended his turn.

-My turn! Draw! -Shiro pulled out a card from her Deck.

-Okay, Shiro! Show me your...!

-I pass.

Nobody, not even Jibril expected that movement. Passing without summoning a monster, or even placing a backrow?

-What is it? I just had a bad hand, that's all -She replied firmly-. C'mon, it's your turn.

-Oh! O-Okay then. My turn! -Yuya drew his card doubtly-. Hey, Shiro. If you want, I'll just pass until you get a good hand...

-Please, don't. I just decided I want to finish this Duel quickly.

-I don't understand, but okay...

Yuya then Pendulum Summoned the monster he just drew: Performapal Cheer Mole (Level 2, DEF 1000). Right after that, he declared a direct attack with Odd-Eyes.

-Go, Odd-Eyes! Spiral Strike Burst!

The dragon shot a large flaming beam out of his mouth towards the defenseless girl. As the attack striked, a huge smokescreen formed around the field.

-Yuya! What are you doing? -Yuzu yelled at him between that dense smoke-. How could you do that to Shiro-chan? You should go easy on a child!

-But she told me to not do that!

-Useless.

-Huh?

When Yuya turned around and the smoke finally dissipated, he found out something out of normal: Shiro still had 4000 LP. And not only that: she had a monster in her field. (Level 1, ATK 0)

-That kind of attacks are just useless -She explained again-. When I'm about to receive a direct attack, I can Special Summon Battle Fader from my hand, which also negates the Battle Phase.

-A card that negates attacks from your hand? -Yuya was impressed. Also, since he could do no more, he just ended his turn.

-Amazing -Yuzu hardly could speak-. She stopped Odd-Eyes' attack just like nothing.

-It's obvious you don't know my Master at all -Jibril said to her while gazing amused on the little girl. -This is just the top of the iceberg...

-My turn! Draw! -When she drew her card, she seemed with even more energy than before-. I summon Symphonic Warrior Basses (Level 1, ATK 600). I now activate its effect, increasing its own Level by the same amount of cards in my hand, and I have 5 cards in my hand, so...

Her monster started playing the bass, and while doing so, its Level raised to 6.

-Now I activate One for One: by sending one monster card from my hand to the Graveyard, I can Special Summon a Level 1 monster directly from my Deck. Appear now, Tuningware! (Level 1, ATK 100). The monster I just sent to the Graveyard was Quilbolt Hedgehog, which can be Special Summoned from there if I control a Tuner monster, just like Basses (Level 2, ATK 800). Finally, if I have no monsters in my Graveyard, I can Special Summon Mirror Ladybug from my hand! (Level 1, ATK 100)

Yuya couldn't just believe it: in a matter of one turn, he fulfilled her whole field with monsters, just like his Pendulum Summon.

-You're incredible, Shiro! Your Dueling is awesome.

-You've seen nothing yet -Shiro cut him with a serious look in his face.

-What?

-When Mirror Ladybug is Special Summoned by its effect, its Level becomes the total sum of levels in my field, meaning ten (Level 10). Now I tune my Level 1 Battle Fader, my Level 2 Quilbolt Hedgehog, my Level 1 Tuningware with my Level 6 Symphonic Warrior Basses!

-What did you say?!

Suddenly, Basses became six glowing green circles that quickly sourrounded the other mentioned three monsters.

-Holy guardian of the nature and its livings! Let your roar tremble this very earth! Synchro Summon! Appear now, Level 10! Leo, the Keeper of the Sacred Tree! (Level 10, ATK 3100)

As it hit the ground, the enourmous lion held out a majestic roar that echoed all around the field.

-A 3100 ATK Synchro Monster! -Yuya was impressed.

-I'm not done yet! As Tuningware was used as a Synchro Material, I get to draw a card. Then, I overlay my Level 10 Leo and Mirror Ladybug!

-Heh?! -Yuzy just coudl't believe it: a Synchro used for an Xyz?

The Overlay Network was then created, and Leo and Mirror Ladybug, now shown as two orbs of light, quickly entered into the center of that vortex.

-From beyound the railway, arriving here and now, alongside the tremores of the earth! Xyz Summon! Come before us, Rank 10! Superdreadnought Rail Cannon Gustav Max! (Rank 10, 3000 ATK)

A gigantic railway then appeared in from of Yuya. Right after, an even bigger block transported by a train was sliding on top of it, with two Overlay Units floating around it. Yuya could tell very well that it wasn't good news to him.

-Now, by detaching one Xyz Material, I can make Gustav Max inflict you 2000 damage points!

An orb of light was ingulged by the machine, that then pulled out an enormous cannon from inside, which was pointing directly to Yuya.

-BIG CANNON!

The shoot was both blasting and violent. Yuya barely could stand up after receiving the hit, although his LP were reduced to 2000.

-Now, my Field Spell Card: Xyz Territory!

Right after activating it, the atmosphere around them was covered by a hundred colors that filled the air. Yuya also noticed that Gustav Max started glowing...

-Whenever an Xyz Monster battles another monster now, Xyz Territory increase that monster's ATK by 200 for each of its Ranks.

-What did you say?!

-Battle Phase! Gustav Max will attack Odd-Eyes now! And with that, its ATK increases by 2000! (Gustav Max: ATK 5000)

-ATK 5000? -Yuzu was shocked.

-Drumming Kong's effect activates now! When a monster I control battles another monster, mine gains 600 ATK during the Battle Phase! But I also activate Cheermole's effect: as an ATK's stat changing effect was activated, I can make that effect become 1000 more than usual, so my Odd-Eyes gain 1600 ATK points! (Odd-Eyes: 4100 ATK).

-Quick-Play Spell! Shrink! It halves your monster's original ATK this turn.

-Like I'll let that happen! Stargazer's Pendulum effect activates now! Once per turn, if my Pendulum Monster is battling and my opponent activates a Spell Card, I can negate it and set it face-down! Sorry, but you won't defeat me this turn.

-You really think so? I activate Mystical Space Typhoon to destroy Stargazer Magician!

A vortex formed and ingulged the Magician, destroying it.

-What the...? -Yuya couldn't even finish.

-Now that Stargazer's gone, its effect won't apply anymore, that means...

(Odd-Eyes: 2850 ATK)

-As I remember, my monster was attacking...

Gustav Max fires a beam from its cannon and destroys Odd-Eyes with it. The impact pushes Yuya away and reduces its LP to 0.

Yuzu was frozen while watching all that: in a matter of a turn, Shiro blocked every move Yuya had and blew his LP like nothing.

-Impossible... Yuya...

-I told you it was useless -Shiro explained to Yuya while she was walking towards him. He stood up slowly, a bit hurt too-. Your technique is not all bad, but has a lot of flaws...

-Amazing, Shiro -Yuya smile at her, albeit his brushes-. You truly are a great Duelist.

-Thanks -She shortly smiled.

-So, you want me to help you find your brother now?

-Why would you do that? -Shiro's tone changed drastically into seriousness.

Yuya thought he misheard her.

-I mean, didn't you want help with looking for your brother?

-Yes, I did. But did I tell you that was the favour I was going to ask you?

He stood there in silence. What was wrong with this kid? One minute, she was crying over her lost brother, and now she was trying to bergain her.

-What do you...?

-I guess you don't see your actual situation, Yuya-kun -Jibril said while floating into their direction, Yuzu following her-. You accepted a wager without even knowing what you were betting in the first place. Now you have to face the consequences.

-What consequences are you...?

Shiro shushed him before he finished. Then, she said clear and out:

-I want you to be my butler.

-Heh? Why would I do that in the first place? You're not making any sense at...

-Butler -Shiro interrupted again-: bring me a beverage.

-Alright, Shiro-sama! -Yuya happily reverenced to her-. What kind of drink would you...?

As soon as he found out what he was just saying, he stayed in awe. And Yuzu wasn't reacting good to it either.

-Yu... Yuya... -She was panicking-. What's wrong with you?

-I... I don't know... -He started trembling-. Something's wrong with...

-Drinks. Now -Shiro stouted.

-Right away, Shiro-sama! -He then ran to the next vending machine he found, bought six or seven cans of drinks and came back to Shiro, all in a matter of fifteen seconds.

-I hope you enjoy any of the flavours I... -He stopped again, dropping the cans all over the floor-. WHAT THE HECK IS WRONG WITH ME?!

-YOU TELL ME! PULL IT TOGETHER, YUYA! -Yuzu yelled at him, confused and frustrated.

-Before we Dueled, you accepted playing with the Pledges after aknowledge them -Jibril quickly explained-. That means, you must follow them.

-What do you...?

-Pledge #6 -Shiro interrupted again-. "Any bet made in accordance with the pledges must be upheld". Now you must be my butler, as that is the favour you wagered.

-Like if I let you do that! -Yuya confronted her-. I'm not going to be your butler just because...

-Butler, quiet down.

-Yes, Shiro-sama! -He then stood up firmly and stopped talking.

-Wait, Shiro-chan! You can't do that to Yuya... -She stopped, as a thought came up to her mind-. This was your plan from the beginning, right? To lure us into Dueling you with the Pledges...

-It was. -Shiro confirmed it like nothing.

-How could you do that? That's unfair!

-It wasn't: you both read the Pledges and agreed to them. Everything was fair from the beginning. Butler, you may speak now.

When Yuya opened his mouth, it was like he could finally breathe since forever. He decided not to waste his words.

-Yuzu! Get some help, hurry!

-What are you talking about? You don't think I can do it myself!

-Don't do it! I don't want her to slave you too!

-But Yuya...!

-Listen to him -Shiro cut her shortly and calmly-. I would trust him if I were you. You just witnessed how I defeated him in a matter of a turn. Do you really think you have any chances to beat me in a Duel right now!

Yuzu was furious, but deep inside, she knew Shiro was right.

-We both know you can't do anything but to call comrades in your support. I can wait: Yuya has its Duel Disk on, so you can localize me whenever you want. But better hurry, who knows what will happen to him...

Yuzu looked at Yuya in fear, but he tried to smile at her in confort.

-Don't worry, Yuzu. I'll be fine. Just go already!

-So-Sorry, Yuya. I promise I won't take long! -She said while runnig away, looking for aid.

When she was far gone, Shiro ordered Yuya to pick up the soda cans and to follow her along with Jibril. They were now walking down the street.

-You'll see, Shiro -Yuya suddenly said. Jibril turned her head around, while Shiro just kept walking without looking at him-. I may not be the best, but Yuzu and I know much more Duelists, some of them way better than me. You won't have it your way forever...

-I wonder about that...

-Heh?

-The goood and bad thing about Duelists, specially from your world, is your altruism and your lack of senses when you are Dueling. Because of that, many Duelist will come in order to defeat me, but I won't go down that easy. And when I beat them and make them my servants, more will come in order to avenge them. And none of them will be able to win because I never play the same Deck twice.

-What the...?

-So thank you, Yuya Sakaki. Thanks to you, much more Duelists will encounter the same fate as you.

Jibril starting giggling at her Master's brilliant plan, and Yuya started sweating of fear, regretting the big mistake he had just made...
