Chapter I: Zero the guardian

I will never forget the night I met him, the word that he uttered to me. Those words I still can't get them out of my mind in fact those words will change my life for the better or worse.

It all started a few days ago I was in the living room with our computer since me and my twin brother Rua spend most of our time inside. We live alone on the highest floor of the tops which is a tall building located in new domino city. Is not like we are orphans or anything is just that our parents have always been busy with their jobs. My brother Rua is a very lively person though he is always cocky and sure of himself. I always point out some of his flaws he either ignores me or try to prove me wrong…he always fails. Despite that I always look up to him for encouragement. Me I am more calmer than him but a lot more frail. Unlike my brother who has a lot of energy when he duels I gets very tired quickly after one. When I was three I went to a coma that lasted exactly one month. That was the first time my parents and us were together. My mom said that Rua never leaved my side until I woke up. While I was in a coma I went to this place called the spirit world were I made a lot of friends and was protected by the ancient fairy dragon the ruler of the spirit world a blue dragon with a golden crest in the center that has four ruby spheres going from her neck to her upper torso. she also has golden with ruby sphere ornaments attached to her hands, a crest crown colored ruby with a sapphire sphere in the center and the lower corners colored in gold. Her hair was the same as mine green while her wings seemed frail but majestic. I spent most of my time here with her and the others spirit until I started to regain consciousness. Before I left however I made a promise to protect the spirit world from harm but I couldn't keep my promise since I was too afraid because of the pressure that I would have to undertake alone.

"Hey, Ruka!" I narrowed my eyes to look to my twin.

"Yes?"

"Let's go outside!"

"Ok." We walked but went opposite directions.

"Where are you going?" I asked.

"Outside, Duh." Wait when he said "Let's go outside" he meant as in outside the tops?!

"Rua, wouldn't be safer if we go outside to the balcony?" I tried to reason with him but as always he waved off.

"Where's the fun in that?! Besides is boooring here." I rolled my eyes there are plenty of things he could do here.

"Come on Ruka, pleeease." I sighed.

"Ok, you win but if we get in trouble…"

"Heh, don't worry I'll show them a thing or two if they trie to mess with my little sis." Little? We are the same age and height the only difference aside from our genders is our hairstyles. While my brother has it in a single high ponytail with two shoulder-length bangs on each side of his face I wear it into two high pontytails. his clothes being a short-sleeved white jacket over a sleeveless dark blue shirt with golden markings that differ from my shirt. He also wears white shorts with a dark blue belt and blue sneakers of the same color. Rua has a bracelet on each wrist. I on the other hand wear a light pink short-sleeved jacket over a long-sleeved red shirt with golden markings. I also wear a light purple shorts with a red belt and sneakers with black and pink markings and high socks.

"Yeah, Yeah."

We were outside and to tell you the truth it wasn't as bad as I thought the streets were clean and the atmosphere was normal. For once my brother was correct still why do I have this feeling.

"Is awesome! I knew it was a great idea to get out!" he looked at me and grinned. "Am I right Ruka?!"

"Y-Yeah." I murmured.

"Still I wonder if they are any duelist around here." I sighed of course.

"Rua." I looked around and started to get a bit nervous. I mean is been eight years since I have been outside of the tops usually the manager is the one who buy our groceries and looked after us now… "Huh?" Something caught my eyes it was brief but I saw someone with a long brown hooded coat that covered its entire body. he or she didn't seem to be tall a head at max taller than us. I couldn't tell if that person was a boy or a girl since the hood hid its entire face but what caught my golden grey eyes was the magatama he/she was wearing. It was a golden crest with the number 39 in the center that was colored in red that on the sides had white wings similar to a guardian angel. My eyes hypnotize by that magatama didn't pay attention to anything else until the snap of my brother fingers. "Eh?"

"Hey are you ok Ruka?" he looked at me in concern.

"Oh, um y-yeah I'm fine." I replied. That's strange why was I so fixated on that strangers magatama?

"You act strange sometimes sis."

"Like you are to talk." I said rolling my eyes before we kept walking toward the city.

The figure walked toward the streets of New Domino City. All the figure needed to know was what year this was and also the target that it was tasked to protect. Underneath it white with the golden on the sidelines were cold icy blue eyes. It silently walked through an ally in order to find someone to duel against that way he would be able to find out the potentials of the rumored monsters that matches the power of his current one.

"Oh look here, a new face." the figure look to see a pair of thugs.

"…"

"What's a matter cat got your tongue?" the leader as he guessed who has short black hair told. the figure narrow its eyes and see that the thug had a black with blue on the sidelines duel disk. he then signaled to the man. "What, I do not understand signal language." the figure activates its duel disk which was colored silver with a bit of gold that glittered. "Oh, that is a nice duel disk you got there buddy tell you what how about if I win you give it to me. what do you say?" the figure didn't answered it just drew its cards.

"I think it accepted." the left thug said.

"I think he did very well."

[Masked Figure: 4000]

[Thug: 4000]

"Since I'm generous I'll let you go first." the thug smugly said before the figure drew. it looks at its cards and then summons a monster. the monster emerged and it was a roman spartan with its face hidden underneath its golden spartan helmet holding a half-red/half-gold shield and a spear. [monster: 4* ATK: 1600] he then proceeded to put a facedown and signaled to him.

"Humph my turn. I summon indomitable fighter lei lei to the field in attack." a orange muscled tiger with brown chest plate and helmet appeared and pound the ground. [Indomitable Fighter Lei Lei: 4* ATK: 2300]. "Now Lei Lei pound that spartan wannabe Ground Pound Tackle!" Lei Lei charge and then knocks the Spartan which shatters and the masked figure loses 700 life points. [Masked Figure: 4000-3300]

"Since my monster attack he is switch to defense. I'll place two cards facedown and end my turn." the thug smirked however it doesn't faze the masked figure who drew its card and quickly the thug played a trap that has Dark Ruler Hades feeling drained. "I activate skill drain by paying 1000 of my life points as long as this card is on the field all effect monsters effects are negated." The figure narrowed its eyes before he looked at the other face-down before activating a spell that shows holographic buildings with three facedown cards and a beam shooting toward the targeted facedown. He then proceeded to signal the facedown and a beam shot from the card pulverizing the targeted card. "What the?" the thug was surprised. the figure then summoned a monster wearing a violet cape, a white with a couple of red lines helmet, with purple clothes, black boots, gloves and chest plates holding a small sword on its left while a lantern on its right [4* ATK:1200]. it signals the monster to attack before this one destroys lei lei. it then signaled to the man in front.

"You'll pay for that punk." he drew. "I summon Convertible Machine Beast, Gunner Dragon." a Golden with red mechanical dragon with gunners on the top side of its heads and tank like wheels appeared roaring. [Converible Machine Beast, Gunner Dragon: 8* ATK: 2800] "Usually his attack and defense would be halved by his effect but with skill drain on the field he is at its full power that is not all I activate the spell Resurrection from the Dead allowing me to resurrect lei lei from the cemetery." lei lei appeared underneath the ground. "Now lei lei destroy his monster." it destroy its monster and the figure loses 1100 life points. [Masked Figure: 3300-2200] "That duel disk is mine go Gunner Dragon end this edge cannon!" Gunner Dragon charge the cannons and shoot them toward the masked figure.

We were walking toward an alley when the explosion make me scream.

"Whoah!" Rua exclaimed. when I looked toward the direction his eyes were looking my eyes went wide the figure that I saw about twenty minutes ago was flying out of the alley. From the alley a large muscular guy with short black hair appeared along with two other people.

"I'll be taking your duel disk now." the thug said. The person started to get up and I swear I heard cracking coming from its mask.

"I wouldn't be so sure of that." said the figure. my eyes looked to see his face…at least the voice sounded like a boy. then the masked split in two and it fell.

"Oh, now you talk after you lost?"

"Who said I have lost." the voice calmly said. His face it was very young if I'm not mistaken he was four years older than I am. he took out its hood to reveal his black hair that reached its shoulder. There were some of his hair that rose up that was colored a glittering silver his eyes were a very dark ocean blue. Something about him stand above it was his face it was so calm and collected yet so cold and intimidating.

"What, but how?! That blow should've taken your life points down!"

"It would've if it weren't for him." [Boy:100] the boy calmly said before a monster that I have never seen before appeared. it was a blue armored knight with two shields as his arms. "You see if I would receive 2000 or more damage from battle I can discard Heroic Challenger- Sword Shield from my hand to negate all that damage and have my life points reduce to 100 instead." Does a card like that exists?!

"Tch, I'll place two cards facedown and end my turn. it doesn't matter what you do I will win that duel disk!" the muscular man laughed.

"Humph, do not be so sure of that, you see I know your deck inside out, it is good that you play a skilled drain deck but you left yourself wide open." the boy said as he drew a card. "If you only would've destroyed my face-down you could've had a chance but your overconfident blinded you, now I activate my facedown go Heavy Storm!" He flip the facedown and indeed it was Heavy Storm creating a strong gust of wind that destroyed not only Skill Drain but the man's facedown cards.

"Tch, big deal. was that your big move?!"

"You should wait and see this duel ends here I summon heroic challenger double lancer to the field." he puts a card and another knight this one with purple on the top, light blue in the center, and white on the bottom helmet along with its armor being white with the exception of the center and its boots being purple. its shoulders and some parts of its armor were also colored light blue. the monster was holding two golden lance in each hand. [Heroic Challenger- Double Lance: 4* ATK: 1700] " Now I overlay the level 4 Double Lance!" Overlay? With one monster?

"Over what?!" Rua and the thug said out loud.

"Usually I will need two monsters to do this but Double Lance allows me to overlay himself as two units." then something happened the sky turned dark as the monster turned into two red orbs. "I create an overlay network with him." then I saw something amazing the ground the surrounding turned into some kind of intergalactic black hole that took the two orbs and a huge explosion occurred. "Xyz Summon!" from said explosion a metalic knight with some of its armor colored red while its helmet has the same color of its armor with a what looked like a golden cross attach to the top of its helmet wielding a big sword with a golden hilt and handle on its left hand appeared from it. "Heroic Champion Excalibur!" [Heroic Champion Excalibur: Rank 4 ATK: 2000]

"S-So you summon a new monster big deal it still not stronger than my monsters so much for ending it in this turn." a smug smirk appeared on his face but then fades when the boys chuckled. "What so funny?"

"Nothing its just that I forgotten that you people not knowing what an Xyz is makes me wonder if they actually exist here." Actually exists? does that mean he is not from here. "Regardless I believe is still my turn now witness the real power of an Xyz! I activate the special effect of my Excalibur by detaching all overlay units from this card I can double his attack until the end of my battle phase!" [Heroic Champion Excalibur's ATK: 2000-4000]

"An ATK of 4000!?" He just did all of this with only 1 card?! I look to the boy with widened eyes, who is he?

"I'm not done I activate the spell Heroic Chance during this turn only I can target one "Heroic Champion" I control and double its attack!" But that means…[Heroic Champion Excalibur's ATK: 4000-8000]

"8000?!" For Rua to have his mouth open would be an understatement but who wouldn't with just two cards this boy was going to defeat this person.

"W-Wait!"

"Too Late Heroic Champion Excalibur attack his Converible Machine Beast, Gunner Dragon: Single Sword- Finishing Move of the True Blade!" The monster then went to Converible Machine Beast, Gunner Dragon and with a mighty swing destroyed the monster sending the man flying from the impact. [Thug: 4000-0]

"Boss!" the others rushed toward him.

"Humph." the boy deactivated his duel disk before he narrowed his eyes toward the other two who flinched in fear. "Get out of my sight before I change my mind." Just then the sound of sirens were heard.

"Is Sector security."

"Let's get out of here boss!" the three thugs ran away.

"Nuisance." I heard the boy murmured under its breath.

"Hey!" Rua what do you think you're doing?!

"W-Wait Rua!"

"Hmm." the boy turned to look at us.

"That was so cool I never heard of Heroic before."

"You'll never will at least not until a long time." he said, so he really is not from here. "Beside I do not have time to deal with brats, right now I have important." the boy froze and he look at his magatama. now that I look at it the magatama was shinning brightly and the boy look toward us which makes me somewhat afraid.

"Hmm." I tug on Rua's jacket.

"What is it sis?" he said turning to look at him.

"We should get out of here you heard those guys sector security might be coming here any minute."

"We will let me…" he blinked a few times before my eyes look at the direction he was looking and then I realize something.

"He's gone."

A few days has passed and we haven't heard from that boy, it was as if everything was a dream to begin with…those monsters and what he called Xyz…is that some kind of new monster that industrials illusion is creating?

"I need something to drink." I stood up from my bed and went to the kitchen to get a glass of water. After I got the glass of water I heard a sound I recognized instantly. "What is it kuribon." I asked to my fury friend while she went to my arms so I could cradle hear. she start to murmur before she fly up and goes to the window. "Hey wait up!" I follow her, why would she be so frantic. I reach the glassed door and look over the balcony right there by the pool was a figure, I hesitated, what's that a burglar? but how could a burglar be there we were on the highest place in New Domino City any one would notice someone climbing up the building. Then something caught my attention it was that robe, I had seen it before. Why my mind set I slowly opened the door. kuribon gave me a concerned look. "Don't worry I'll be fine." I reassure her although I was doubting myself, what if he isn't who I think he is but then again it would explain how no one has notice. I walk slowly it seems he was looking at the moon, I have to admit it was beautiful and the stars surrounding the dark sky made it more beautiful. I got slowly close and it confirmed my first question it was indeed the boy still there was one question that I wanted him to answer but before I could muster the courage to say it he beat me to it.

"What are you doing here?" he asked without turning…what am I doing here? This is were I lived! I should be… "That is what you were going to ask me, right?" Wait he knew? How? He turned and once again our eyes collided my golden grey with his dark ocean blue. "Well?" That snapped from my trance then I noticed his magatama glowing higher.

"Y-yes." That's all I could muster, I was nervous I have no idea who this boy was and it doesn't help neither if he keeps looking me up and down.

"I see." he let out a sighed as if he was expecting something. "Well at least I found you." Found me? What is going on? "I guess introductions are in order." he said as he threw the robe that he was wearing causing me to shut my eyes instantly. "Hey." I opened my eyes to see him in clothes. the boy was wearing a black jacket with some kind of big ruby orbs on his shoulders, a white shirt with a golden crest design similar to its magatama with the exception of the number 39 in it. on his hand he was wearing fingerless black gloves while on his lower body he wore long dark blue jeans with black boots to match. After I looked at him he caught his robe with his left hand and then pointed toward me. "Listen and listen very well…" I gulped and nodded slowly. "My name is Ichigo Zero and from here on out…" he said and the next four words could change my life for the better or worse. "I'll be your guardian."

"A Guardian protects a person that they are tasked to protect,

why can't it be the same for the person who is protected?"

Man it took me forever to make this but I guess this would help me get back on track with my stories in fictionpress, trust me if I don't write everyday I'll become super lazy. Well what can I say this is my first OC/Ruka fanfiction though the story will focus on Ruka and Ichigo Zero, Fudo Yusei will still be the main character of the series, hey I like my OC's but that doesn't mean that I will still one of my fav. main characters spots by making Zero duel all the main ones. As for the Xyz and the monsters yes Zero is from the future but the events of Yliaster still happened it just that he was in a place far away from New Domino City when it happened and it was spread to the world. The magatama has a major role in this story but it will take time so yeah. Thanks for reading and I will see you next time.

If I have to chose and opening and ending for Zero's Legacy I will choose these:

Opening: Seikon No Qwaser's opening 2- Baptize

Ending: Gundam Age Ending 2- My World

Converible Machine Beast, Gunner Dragon= Fusilier Dragon, the Dual-Mode Beast

Resurrection from the Dead= Monster Reborn
