Son of Sin

A/n: I do not own naruto or the seven deadly sins

I got this idea from watching the seven deadly sins on Netflix after episode sixteen, this means that I have not read the manga and have not actually watched passed episode sixteen. Any information I have from later in the series was found on the internet, I am also ignoring the rest of the series in my story so please do not comment that something doesn't match the original series (this is a fanfiction after all). Also, for those that do not like an op character you should turn away now as I am making naruto pretty op, but he will not simply take out all those that challenge him nor will he simply op his battles right off the bat or take a fight from another character.

Warnings: this is rated m just to be careful so there may be swearing, violence (if I'm not too lazy), and a yaoi pairing (again if I'm not to lazy), Other than that enjoy.

Chapter one

Beginning of sin

Meliodas the dragon sin of wrath smiled to himself as he and three of the other sins Diane the serpent sin of envy, Ban the fox sin of greed, and King the grizzly sin of sloth walked through the fairy kings' forest. King was ecstatic to see the forest healthy and teeming with life, after nearly two hundred years the forest had started a new once again. Looking at the moving plants of the forest made Meliodas think about what had brought the group to the forest that held so many memories for two of their group.

Flash back two years ago

Meliodas groaned as he woke with an intense hangover and tried to remember what had happened the night before. A groan of protest shifted his attention to the body that was lying next to his, blinking a few times he recognized the form of Diane who was small enough to sleep in his bed, but the troubling thing was that they were both naked. Diane lifted her head still sleepy as she yawned before taking notice of her surroundings and let out an ear-piercing scream.

"CAPTIAN!" not a second later ban and king had busted down the door with Gowther trailing in behind them.

End flash back

It had been a hectic morning in the hog's hat with Diane holding her stomach in joy while being slightly annoyed that she couldn't remember it or how it happened. King tried to deny that it happened at least until Gowther found the subconscious memories of their night together. Ban just sat back laughing his head off, soon Meliodas got everyone to calm down telling them to wait and if nothing happened it would be fine.

Nine months later Diane rested in a room of the castle with the kingdom of liones current queen sitting by her bed and coaching her through the birth of their son who she named naruto. The child was human sized most of the time but if he saw Diane in her giant form he would grow into a giant as well making him the same size as the average horse drawn cart. After ten months of life naruto became fairly attached to king always wanting to fly with him and be near him, the child had even managed to steal Chastiefol in its pillow form for a nap more than once. Knowing how happy it would make Diane and the child king asked if they would come to the fairy's forest so he as king of the fairies could bless naruto. Diane was so happy Meliodas instantly agreed, when ban and Gowther heard of the trip they insisted that they go along having grown close to the child.

The month they spent on the road was strange to say the least as naruto started to show signs of being able to use his parent's abilities. Ban looking for entertainment on the long ride tried to teach naruto his ability it was a surprise when he used a weak form of snatch to grab an apple. Ban, Diane, King, and Meliodas had watched carefully as Gowther tried to teach his own ability to the child who only managed to spark his fingers lightly thou naruto thought it was all great fun and clapped ecstatically. As soon as they had arrived king had led them to the top of the holy tree where he chanted in an ancient language while placing his hand on top of naruto's head. A green light covered naruto for a few seconds after king finished speaking; when it disappeared naruto looked up at king in confusion before he started to float off the ground a little.

They had been there for nearly a week playing among the trees and hanging out on top of the holy tree letting naruto enjoy his time in the fairy forest as he connected with the forest. Gowther had stayed on top of the holy tree to look after naruto while the other sins went to look for fruits and clean water. Meliodas and the others stopped dead in their tracks when they sensed something was off, rushing up the tree they found Gowther sitting in front of naruto pulling a chalice that looked to be made of clay out of the child's hands. Ban and king stopped dead in their tracks recognizing the chalice for what it was.

"What are you doing with that, how did you even find it?" king asked as he floated over to Gowther, Gowther tipped his head to the side with a blank look in his eyes as always

"I didn't find it naruto did, he managed to drink it all before I could get it from him. Why? What is it?" king fell to the ground while ban gently lifted naruto into his arms.

"That was the water from the fountain of youth" king sighs as he picks up the chalice

"With the forest starting over the fountain must have tried coming back as well, imagine the chances that naruto managed to find the only cup of water the fountain had managed to produce" ban chuckled as naruto reached up pulling on some of his hair. That night they sat in the hog's hat laughing and enjoying each other's company while naruto slept soundly on Chastiefol.

Time skip two months

The group had taken the scenic root back to the capital stopping in small towns and villages on the way back. Opening the doors to the throne room Meliodas smiled as naruto crawled as fast as he could to the queen who laughed in delight at seeing the child. She was about to speak when a holy knight ran into the room.

"My lady there is an army surrounding the castle, it's the kingdom of Doran" the sins went deathly quiet; it had been a great fear of the queen's that they would attack in an attempt to steal the treasures of liones for themselves.

"Head below the castle your highness we won't let you down" Meliodas said as he and the other sins got their weapons ready. The queen nodded gently taking naruto in hand as she carried him to the last room in the very bottom of the castle with a squad of four holy knights who waited outside the door to take care of anyone who managed to slip in. naruto and the queen waited in the dark by the horn of cernunnos for hours on end the thick doors locked and barricaded when the sounds of battle began outside the door.

Queen Maria looked down to the innocent child in her arms and knew that she would not allow him to be taken by the enemy. Rushing to the horn of cernunnos moving through the ritual quickly it wasn't long before she heard the voice of the goddess.

"Queen Maria of Liones why have you called me" the voice betrayed no emotions as it spoke.

"Goddess I have called you now as my knights have fallen, my people killed or taken, and my kingdom about to fall I ask that you spare this one soul, take this child somewhere where he will not be harmed by this world, please". The room was silent the only noise coming from outside the door as the enemy attempted to bring it down.

"Very well I shall take him to a new world where he may live" Queen Maria sighed in relief as a bright light surrounded the boy before disappearing with him just as the door was thrown open revealing the armor of Doran's king as he admired the ancient horn as one of liones greatest treasures. Maria took the spear from in front of her before slashing through the horn turning the ancient material to dust. Turning the young former queen stood her ground with her spear pointed forward watching as a blood covered knight came to kill her, and with her ended the life of the last person loyal to the kingdom of liones in the capital.

New world

Five years after naruto's arrival

The clouds hung heavy over konoha the village hidden in the leaves as heavy rain poured from the sky. Walking down a deserted ally was a young child wrapped in a flimsy cloak and ragged cloths as the rain soaked him thru to the bone. At the end of the ally stood a high fence that surrounded a massive forest like no other in the world, this was where the child called home. The wind blew back the hood of his cloak showing bright blond hair and crystal blue eyes to the world.

Naruto, an orphan found the night of the Kyuubi's attack five years ago. He didn't know why the villagers shunned him, called him demon brat, and kept their children from meeting him. He knew he was different since the first night he had been kicked out of the orphanage, when he had found the forest with the dangerous animals.

Flash back

Naruto sat against a tall tree as he cried while the cuts he had gotten climbing in to the forest that littered his arms and hands healed before his eyes, when a loud growling came from in front of him. Stepping into the clearing was a large tiger growling hungrily at the meal before it, without a second thought the beast charged. Naruto screamed as he raised his hands in defence and closed his eyes tightly, but after a few seconds with nothing happening naruto turned to look back at the tiger. The tiger was still in the air suspended in place by spears of rock that had punctured through its limbs and chest.

End flash back

Since that day naruto had stayed in the forest only coming out to see the hokage and the ichiraku family. Naruto sighed as he curled up in the tree hallow he had been using as a home *where is my family? Dose no one want me? Maybe the villagers are right, and I shouldn't have been born at all* with that thought naruto drifted off to sleep.

Mindscape

Drip . . . drip. . . Naruto blinked open his eyes as the sound of water dripping woke him up. Sitting up carefully naruto looked around at the sewer he was apparently sitting in. getting up naruto wadded thru the water deciding it would be best if he managed to get out of the sewer first before he thought about how he had ended up there. It felt like he had been walking for hours on end before he finally managed to hear voices and laughter coming from up ahead of him.

Approaching the only bright light in the near darkness of the sewer naruto came upon the strangest sight he had ever seen. A giant nine tailed fox sat on one side of the room behind a golden cage while in front of the bars sat five other people. One was a woman as tall as the fox with deep brown hair and wearing what almost looked like an orange swim suit. The next was a young-looking man and the smallest of the five, he had light brown hair with some odd cloths but what really caught naruto's attention was that the man was just floating there in midair.

The next man was average height with spike silver hair and all red cloths; he was leaning back laughing at something. Beside him sat a younger man who was slightly shorter with dark pink hair and glasses with a blank look on his face. Sitting just before the cage was the last person in the room, he had light blond hair but with his back to naruto the boy couldn't see anything else. Naruto coughed slightly trying to get their attention, it worked as all of them became quiet and turned to see who the uninvited guest was.

"Ah. So, you finally found your way here huh?" the blond said as he stood and walked over to naruto. Naruto watched as the man quietly walked around him before giving him a pat on the back and moving him closer to the group. Soon he was seated in their little circle on the floor "I'm sure you have many questions so ask away".

"Where are we? And who are you?" naruto asked as he looked them all in the eyes noticing the strange colors they had. The blond beside him smirked before laughing outright causing the others to join in except the tall woman who simple kept a soft smile on her face.

"So, you stumbled in here on accident huh. Well naruto we are in your mindscape right now, meaning you mind. As for who we are the giant fox is kurama the Kyuubi, the guy with silver hair is ban the fox sin of greed, beside him is Gowther the goat sin of lust, the one floating beside me is king the grizzly sin of sloth, the tall lady here is Diane the snake sin of envy, and I am Meliodas the dragon sin of wrath, we are five of the seven deadly sins; but you can call me and Diane dad and mom respectively" naruto stopped for a second as he processed this information before tears filled his eyes and jumped on the man who said he was his father.

"W. . W. what happened to you? Why are you in here?" Meliodas sighed as he hugged his son for the first time in five years.

"We didn't mean to leave you naruto. You see we are not originally from the elemental nations; we come from the kingdom liones in a completely different dimension. Two months after your first birthday an enemy kingdom attacked ours, the seven deadly sins were the greatest forces our queen had so while we were fighting she took you with her deep into the castle. The enemy didn't care who they killed be it civilian or soldier, they slaughtered everyone. Diane and I were the last sins to fall by that time over half the enemy army had been killed but still more came. When it was clear that we had lost Queen Maria asked the goddess to send you somewhere you could be safe from our enemy's. The goddess sent us here so that we may help you learn to control the power inside of you, so you don't accidently kill yourself or anyone else."

Naruto nodded as he sat comfortably in his father's lap before he looked up at the woman who was supposed to be his mom. "How are you so big?" his mom had a slight blush as she spoke.

"Well I am a giant, so I'm supposed to be this big, and before you ask there is a plant in our world that can shrink people for a few hours at a time. When you were younger you showed the ability to choose if you wanted to be in your giant form or not." Diane smiled as naruto looked at her with sparkling eyes.

"You mean I can become as big as you, that's so awesome" his father and ban were laughing while king floated a little closer on a big fluffy pillow with a relaxed smile.

"You can do quite a bit naruto, when you were younger you showed the potential to use all of their abilities and with my blessing I made you my heir." Naruto looked up at king in confusion while Meliodas tightened his hold on his son.

"Naruto king's real name is harlequin the fairy king. But for now, you better go to sleep tomorrow we'll begin training you in our powers we only have six more years to train you" naruto looked into Meliodas sad eye's

"What do you mean" Diane gently picked naruto up and held him in front of her face.

"Our time is done naruto; we don't belong in the living realm any more. Someday a very, very, very long time from now you might join us but not before you have lived a long life" naruto nodded still sad but at least he didn't have to say goodbye right then. A large yawn escaped from him as his eyes started to droop, Diane set naruto down on Chastiefol as it shifted into its guardian form of a giant stuffed bear and wrapped around the child.

The next day

Naruto woke to the chirping of birds in the high branches of his tree. Yawning he was about to go about his day as usual when he remembered his dream from last night. "It couldn't have been just a dream, right?"

*of course not, we're all still here* naruto jumped at the voice that sounded like his father. *I am your father, now we only want to explain things once so is there any one that you want to know about us*

"Is it okay if we tell hokage jiji?" naruto asked slightly scared that he would have to keep it secret from the man he felt was his grandfather.

*of course, we can son, you'll just have to get him* naruto sighed in relief before he nodded his head and jumped out of the tree he was in, going much farther than he expected.

*this is what we were talking about last night naruto, it's also why we were waiting for you to mature a bit more, so your body could take the training that it needs to control your natural strength, speed, and agility* naruto smiled a bit when he thought about the night before as he moved to the edge of the woods and into the village. Like every other day the civilians glared at him and whispered behind his back, those with children moved them as far as they could from naruto. It took a little while before naruto had made it to the top of the hokage tower from the outside.

*eh, son why are you climbing the outside of the tower* his mother asked as he finally reached the hokage's office window. *the secretary doesn't allow me through the lobby, so I can't see hokage jiji unless I come in through the window* he answered as he began knocking on the window, he only waited a few seconds before the hokage opened it.

"let me guess the secretary?" the hokage asked, he was an old man with grey hair wearing white and red robes. The hokage smiled as he helped naruto climb in through the window before he walked over to the office door and opened it to see the brunet woman sitting at a desk. "ami your fired" there were a few sputtered protests from the woman on the other side of the door as he closed it. Naruto fidgeted in his seat as the old kage sat back in his chair.

"Sorry" the hokage chuckled slightly as he looked naruto in the eyes.

"It's not your fault naruto, their job is to inform me of any and all meetings or requests for my time. They were fired because they clearly were not doing that job, now what is it you needed." Naruto smiled brightly as he leaned on the edge of the aged leader's desk.

"It's a very important secret" naruto said completely serious. The hokage paused at the serious attitude before he nodded and sent the hidden anbu away. When the hidden anbu left the room, he touched a small seal hidden under his desk that caused the room around them to turn blue.

"That was a privacy seal, nobody will be able to see or hear what is being said in this office" naruto nodded as he moved his chair in front of the hokage. *alright kit get the old man to look in your eyes and I can bring him in here* said a new voice in his head that he assumed was kurama.

"Hokage jiji I need you to look me in the eyes okay" the hokage nodded as he looked directly into naruto's eyes. Naruto's eyes turned blood red trapping the hokage and pulling him deep into the boys' mind.

Mindscape

Hiruzen Sarutobi gasped as he found himself in a deep and beautiful forest that held a giant tree in the center of the forest.

"Come on hokage jiji" naruto smiled as the hokage followed after him to the big tree where he could feel his parents and the others. Naruto and the hokage took a few moments to climb the giant tree before they were lifted into a giant hand. Hiruzen was shocked at the size of the woman in front of him while naruto was more than happy to see his mom again.

"Naruto do you like what we did, the sewer theme of your mind was just too depressing, so we made it into a replica of the fairy forest" Diane smiled as she set them down near the others. Ban grabbed naruto for a hug while Meliodas looked over the man in front of him.

"So, you're the leader of naruto's home?" the hokage nodded with an aged sigh leaving his lips.

"I know that they don't treat him well, but if I tried to do something about it now the civilian council might take my vote away on anything truly important regarding naruto. Sighting that I'm biased toward the boy, as if they themselves aren't biased against everything to do with him." Meliodas smiled slightly, he could hear the sincerity in this man's voice he would protect naruto as much as he could.

"Well then you might want to sit down this will be a long explanation" hiruzen nodded and sat down by the giant woman. "First off as we told naruto yesterday we don't come from your world but another dimension where the kingdom of liones used to stand. It was attacked by an enemy we could not defeat; naruto was the only one to make it out of the capital alive because he was sent here."

"Before its fall liones had seven warriors who stood above all others, they were known as the seven deadly sins. I am the demon Meliodas the dragon sin of wrath and leader of the sins; I am also naruto's father. The giant beside you is naruto's mother Diane the serpent sin of envy, beside her is the fairy king harlequin the grizzly sin of sloth who has named naruto his heir. The one holding naruto is ban the fox sin of greed and beside him is Gowther the goat sin of lust. We are here to help naruto gain control of the immense power stored within him and train him to use our sacred weapons." Diane was the next to speak as hiruzen's mind moved a mile a minute.

"From my side of the family he'll be able to use the ability of all giants known as creation, it allows you some control over the earth. He'll also get my weapon Gideon which will help him focus his power over creation. Thou because of how he was conceived he gained the ability to choose whether he wanted to be in his human form or his giant form. Once he's all grown he should reach a good thirty meters tall." Hiruzen and naruto gawked at her for a few second as they thought of naruto standing near the same height as the mountains of kumo. King sat back against Chastiefol as he explained what his blessing meant for naruto.

"As the king of the fairy's my blessing means that naruto is a fairy in all but birth, this also makes him my heir. The ability's he'll gain from this is that of levitation and flight as well as control of my weapon Chastiefol and a weaker form of an ability known as disaster. Disaster can cause a small scratch to turn into a major wound, a mild poison into a lethal toxin. It also grants him a slight control over plants and vegetation." Ban smirked as hiruzen turned to him.

"The reason Gowther and I are here is because naruto as a baby showed the potential to use our abilities. My ability is known as snatch, it allows me to take physical objects and abilities from other creatures. Thou when we traveled to the real fairy forest naruto drank water from the fountain of youth making him pretty much indestructible, well unless you counted a few very rare items in our world, but he won't have to worry about that he will still feel the pain thou. Gowther's ability on the other hand is called invasion it lets him access the mind and memories of anyone it hits." Meliodas smiles at his son as he begins to speak.

"Even without training you will have immense speed, strength, and agility; a naturally very, very long life, as well as enhanced durability, healing, and endurance. Being a demon, these areas will naturally surpass what normal humans are capable of, however there are a few who may be insane enough to try and train their bodies to such heights. One of a demon's true strengths is the manipulation of dark matter, it can be used to protect cuts while they heal or reattach limbs until our natural healing reattaches it completely. It can also be used to form weapons, armor, and even wings to allow flight; when used as a weapon dark matter will obliterate any matter in front of it that is not powerful enough to fight against it. Other than that, you will be getting my weapon the demon sword lostvayne and we'll see if you can use the enchantment hellblaze."

The hokage was silent for a while as he thought about all the power naruto possessed even without the use of Kyuubi's chakra. He would need to take naruto to a closed off training area, so no one would see him, the civilians would have all the ammunition needed to force naruto into danzo's weapon program either that or have the boy executed not that it would work very well. Looking back at the boy's father he sighed.

"I'll see if I can get him to a closed off training area so no one accidently gets caught in an attack" turning to naruto hiruzen smiled slightly "now naruto I know you'll want to brag about this at the academy but you must promise me that you will not tell anyone else at least until you're a genin alright" naruto nodded a little put out by the fact that he couldn't tell any of the others about his amazing parents or the awesome abilities he would be learning to control but he just kept thinking about how awesome of a prank it would be to fool everyone into thinking he was actually the dead last of the class. "My last question is about the weapons you're giving him?"

King smiled as he held up his pillow "this is the resting form of the spirit spear Chastiefol, it has seven different forms each with their own capabilities" seeing the hokage's disbelief king reached into his pillow and pulled causing it to transform into a long silver spear that floated beside him.

Meliodas reached into a seemingly empty sheath before pulling out a short sword that looked like it had green scales on the upper half of it with five holes along the blade. "This is the demon sword lostvayne it can create four physical clones that are half the power of the last clone. It also amplifies my ability full counter, which sends an opponent's magical or chakra-based attack back at them twice as strong as the original attack" Diane slid a ring off her finger, stood up and tossed it into the air. The ring grew and changed into a giant bronze hammer.

"Hehe the war hammer Gideon, a great focuser for the power of creation but strong enough on its own to crush boulders, take chunks from mountains, and cause earth quakes." The hokage nodded as he looked over the weapons and Diane.

"Well the only training ground I can think of is the hokage's personal training grounds deep under the hokage monument. If naruto could come and find me after he's done at the academy, then I can take him there to begin his training" Meliodas nodded thanking the man as Kyuubi sent him back out of the boys mind. Noticing the sun was high into the sky already the hokage smiled down at his surrogate grandson. "Well naruto it should be time for lunch by now, how about we go get some ramen." Naruto yelled out in excitement acting like the child that he is and not the weapon many would likely see him as.
