Chapter 1

Notes - I've noticed that there is a lack of Naruto/ Shingeki no Kyojin fanfics so I'm gonna give this a go/DISCLAIMER: I've only watched the anime till season 2 and I'm not bothered to read the manga. I feel like the anime conveys more such as the animation and emotions behind the voice actors and such. Some people might say that I'm ignorant for not reading the manga but that is my reason. Anyways this story will be sort of an AU. So enjoy.(21 Mar 2018)

FARMLANDS OF WALL MARIA

A ripple like distortion disturbs the tranquility of the peaceful farmland. Something flew out of the distortion and into one of the trees nearby. The distortion then crumbles on itself and vanishes as if it was never there in the first place.

Upon closer inspection of the object that hit the tree, a boy could be seen, wearing a tattered fishnet shirt that has its sleeves torn off, orange pants, black combat sandals and a black hitai-ate with a spiral symbol engraved onto the metal plate. The boy has medium length spiky blond hair, azure eyes, slightly tanned skin and has three whisker markings on his cheeks.

"Urghh…that hurts" groaned the boy as he stood up and balances himself with the tree while trying to get rid of his headache. After a few moments with his head cleared up, the boy takes a better look at his surroundings. 'This doesn't look like Hi no Kuni at all.' thought the boy.

Suddenly, a deep voice spoke in his mind "Naruto, I sense something's different, try going into Sennin Mōdō".

"Hmmm, good idea Kurama," replied the boy now known to be Naruto. Naruto places himself into the lotus position and closes his eyes. Orange pigmentation started to fade in onto his eyelids. After a few more seconds, he opened his eyes that now have changed into eyes with amber irises with a black horizontal bar that replaced his circular pupils.

"Huh you're right Kurama, this is weird, the Nature Energy feels similar but vastly different at the same time" muttered Naruto. Naruto closes his eyes again and when he opens them up again, he is in a different place where he is standing on water situated in large corridor. In front of him, is a mountain-sized orange fox with not one but nine of his tails waving around like flames on a candle. The fox is known as the Kyūbi, the most powerful tailed beast. Most people that have seen the fox would have be scared out of their skin but not Naruto who is calm and is in a thinking pose pacing in front of the giant being.

"Hmmm, I think Kaguya pushed me into one of her other dimensions before she was fully sealed but this can't be her dimension. In her other dimensions, there was no Nature Energy for me to absorb so this world has life in it but I also sense weird disturbances quite a distance away." Naruto said his thoughts out loud or is it? He's technically still in his mind but before he could continue his thoughts further…..

"NARUTO!" roared Kurama.

"What!?" Naruto shouted back.

"FOCUS!" said Kurama as he released a sigh. The boy can be a handful at times.

"Ouh right gomen hehe," said Naruto with a sheepish look.

With that Naruto exited his mindscape and walks to a stream in front of him. Crouching at the bank, Naruto saw his face. Nothing weird is on his face, that's good. He can see the orange pigmentations are gone and his eyes are now back to their original colour.

His clothes has seen better days so figuring out that he has to change his clothes so he can better move and be more comfortable, Naruto pulls out a black and orange scroll from his pouch. He applies chakra to the seal in the scroll and after the chakra smoke disappears, a brand new set of folded clothes are on the scroll.

The clothing consists of a black shirt with an orange zipper down the middle with buttoned up sleeves, a white T-shirt, a vibrant red scarf, an orange pants and a pair of black sandals. Luckily for Naruto, this gift from Jiraiya-sensei before he passed on.

Naruto decided not to wear his hitai-ate as he was not sure whether there are shinobi in this world. He also decided to wear his scarf as the weather is pretty chilly out here and he sealed his previous clothing back into the scroll.

After fully clothed, Naruto climbed up a tree to get a better vantage point of the forest. From the top of the tree, Naruto could see two walls from either side of him. On his left, is a large wall with a gate with a emblem of a woman's head on it, on his right is the same large wall that seems to run on forever.

Naruto decided to go to the wall on his right to get a better understanding of the place and also its where he sensed the disturbances nearby. With that current goal, Naruto jumps down from the tree onto a branch and started running across the land with speed only a shinobi can achieve.

While running, Naruto asked his partner "Kurama do you know any inter-dimensional techniques or ways to go home?"

'No I don't, which means we're stuck here likely forever, I'm sure the old man will come up with a way to release everyone from the Mugen Tsukuyomi' said Kurama.

"Yeah you're right, no use in worrying there. Rikudō-jiji will come up with something. And this world is even weirder, the living things in this world don't contain chakra at all. Looks like Senjutsu will be very helpful here." said Naruto.

BACK IN SHINOBI DIMENSION

The members of Team 7 was able to seal Ōtsutsuki Kaguya but somehow before the sealing was fully completed, Kaguya managed to throw Naruto into one of her dimensional portals. The three remaining members of Team 7 was summoned back by the Rikudō Sennin from Kaguya's dimension back to their own before they could search for Naruto. They explained everything to Ōtsutsuki Hagoromo and the remaining 8 bijū.

"There's nothing to worry about young ones, Naruto will be fine, he has Kurama and the chakra of the other bijū with him. Well that concludes the story of Uzumaki Naruto. Uchiha Sasuke I will need my power back to release everyone," said Hagoromo as he took the Moon seal from Sasuke. Sasuke buckled over as he felt his Rinne-Sharingan disappears as well as his sage chakra.

"Sasuke-kun are you alright?" asked Haruno Sakura concerned for her former teammate. Sasuke only replies with a grunt.

"Wait Rikudō Sennin-sama, is there any thing we can do to get Naruto back?" asked Hatake Kakashi, the previous jōnin sensei of Team 7.

"Hatake Kakashi I'm afraid there is nothing we can do. Somehow my mother manages to throw Naruto into a different dimension that isn't one of hers. The sealing must have affected her powers somehow. There is nothing we can do but move on with our lives but I would refrain from telling the people the real reason why young Naruto is no longer here with us," said Hagoromo as he clapped his hands together and the branches of the Shinju withers and unwraps from the bodies of the shinobi that it enslaved.

With that, the shinobi world is saved, the Fourth Shinobi War is over, but all with the sacrifice of one Uzumaki Naruto. Sakura and Kakashi don't know what to feel, they'll never see Naruto ever again. Sasuke only stood up and walked away from everyone and Kakashi has a foreboding feel that won't be the last they'll be seeing Uchiha Sasuke.

BACK WITH NARUTO

It took Naruto a few minutes to reach the top of the wall. The sight that he was greeted to was not one he thought could happen. At the bottom of the other side of the walls were giant humanoid like figures with reddish pink like skin. All of them had weird goofy expressions and were clawing at the walls trying to get it or climb over it but their actions were proven futile as Naruto could safely say that the walls were 50 metres in height after climbing it.

He entered Sennin Mōdō again to confirm his suspicions and he was right. These giant things are the source of the major disturbance in the Nature Energy around him. Their life force seems to be twisted. With Sennin Mōdō, Naruto can sense living things around him and while those things are living beings, their life force seems to be severely twisted.

They seem to sense him as those giants stared up at him. It makes a shiver goes down his spine as those giant with weird expressions were looking at him like he's their dinner. 'Out of all things, I did not expect that,' said Kurama. "Yeah I can totally agree with you buddy, I think we better go to the other side of the wall now, hopefully we can find civilisation" said Naruto as he's trying to get rid of the images of those things in his head. Those giants are nude but they didn't have any reproduction organs from the looks of it. Naruto shudders as he thought more about it. He quickly shook his head to get rid of them and started his journey to the other side of the wall with the gate.

Along the way, Naruto tried several of his other techniques such as the Rasengan, Kurama Mōdō, Rikudō Sennin Mōdō and Rikudō Sennin Chakura Mōdō. Let's just say it failed spectacularly, the Rasengan Naruto created destabilises before being complete, his other chakura mōdō all flickers on and off showing signs of destability. The only mode that works other than Sennin Mōdō is Rikudō Sennin Mōdō as that is a better version of sage mode where his irises are amber but has plus sign pupil. 'I guess my chakra network is all kinds of jumbled up now, I can't use any of my techniques that requires massive amounts of chakra…..urgh that sucks. Kurama can't you do anything?' asked Naruto through his link. 'I'm trying my best here, it's going to take a while, somehow being transported to another dimension scrambles with your chakra network. We have to stay low for now Naruto,' replied Kurama.

'It seems we're halfway there.' thought Naruto but he suddenly stops.

'You feel that Kurama?' Naruto asked his partner.

'Yeah, I sense negative emotions nearby,' replied Kurama.

Naruto makes a quick detour to where he sensed the negative emotions. While running as fast as he can is his condition, he quickly entered Sennin Mōdō without the need of being still as Kurama is already collecting Nature Energy for him.

Naruto could sense 6 people nearby with 2 more further away. 3 of the 6 people nearby are the source of the negative emotions. Suddenly, there were 5 people nearby. Naruto quickens his pace as he has a bad feeling about this.

In a wooden lodge located in the farmlands of Wall Maria, a family of three were enjoying their time together. A cheerful young girl with raven hair with greyish blue eyes is being taught by her mother a stitching technique used by their family. The mother is woman that seems to be in her mid thirties and has raven hair reaching just past her shoulders with bangs that parted through the middle.

"This style of embroidery has been passed down in our clan from generation to generation. When you have a child, it'll be your turn to pass it on too!" said the mother.

"A child? Where do babies come from Kaa-san?" asked the girl. The mother then quickly throws the question to her husband that is sitting opposite them.

"Uhh, why don't you ask your Tou-san Mikasa?" replied the mother with small blush on her face.

The innocent girl then turn towards her father for answers. "Uh…ummm you see babies come from-" said the father as he tried to come up with an answer but he was saved from embarrassment by someone knocking at their door.

"AH that must be Dr Yeager, I'll get it," said the man as he released a sigh of relief of escaping his daughter's question.

"Ah Dr Yeager I didn't expect you to reach so soon-" said the father but he is interrupted as the man in front of him had just stabbed in the stomach with a knife.

The father then collapsed on the floor. The man with the bloodied knife enters the house, behind him, were two other guys; one holding an axe while the other seems to be unarmed.

"Hehe you two lovely things need to come with us" said the man in front with a grin. Mikasa and her mother are shocked that her father and her husband was just murdered right in front of their eyes.

Mikasa's mother quickly took Mikasa and backed away from the three men with Mikasa behind her. Mikasa's eyes are wide as she is still filled with shocked. Mikasa's mother seeing there is no opening for them to run away, she formulates a plan for at least Mikasa to run away.

She quickly grabs the scissors on the dining table and charges at the the man that killed her husband. "ARH YOU KILLED MY HUSBAND!" screamed Mikasa's mother as she goes for the stab. But she didn't make it very far.

The man holding the axe intercepted her mother with a strike from the axe diagonally from her shoulders. Blood spurted out everywhere as the wooden floor is now soaked with blood. The third man then scolded the axe-wielding man for killing their income and now they only have one Asian left to be sold.

Mikasa's mother then looked at Mikasa and shouted for her to run as she took her last breath "RUN MIKASA! DON'T LET THEM GET YOU!"

Mikasa tried to move but her body but her mind is blank. She just saw both her parents get murdered in cold blood.

"Wha….what are you going to do with me?" whispered Mikasa.

One of the man then said "Don't worry, we're not going to hurt you, we're just going to sell you to someone who's interested in you. Let me tell you something, before the walls were built, there used to be a race of people called Asians and they're now extinct except for you. You and your mother were the last remaining few asians around. People would pay good money for your kind!"

Mikasa could not believe what she just heard, she's going to be sold and kept like someone's property. Suddenly, one of the murderers, the unarmed man falls face first with a weird looking knife embedded unto the back of his skull.

The other men turned around just in time to see a blonde haired boy rushing in at them holding another one of those weird looking knives but it was too late for the man with the axe as his throat was sliced open by the boy.

Mikasa while watching everything unfold, manages to grab the scissors her mother used and hides it under her sleeve.

The man with quick thinking grabbed Mikasa and positioned the knife at her throat.

"Stay back or I'll kill this girl!" said the man obviously desperate.

"No you won't, she's your income isn't she?" said the boy with a stoic expression as he stands opposite of the man with his arms crossed.

"Stay back! I'm warning you!" shouted the man.

The boy only took another step forward and said "I want names, who ordered you to do this?"

"His….his name is Arnold Brown, a collector with interests in girls of different races," said the man as he was hoping this would help in the boy in not taking his life.

During the whole ordeal, Mikasa could only keep her eyes locked onto her blonde-haired saviour. He is like her sense of security at this point and she was afraid if she looked anywhere else she would regret it.

Mikasa is too scared to do anything, her legs are shaking with fear but one thought was running through her mind 'I have to do something, I have to fight! I'll always lose if I never fight!' thought Mikasa as something clicks in her as her resolve becomes firm. She remembers all the time where the natural predators ate their preys from cats eating rats to other animals that she saw in the farm but she chose to simply ignore it but now she sees the world for what it truly is.

She quickly plunges the scissors into the man's stomach. The man let go of Mikasa as he felt the pain registered into his body. The man looks at Mikasa and tries to at least kill her before he dies but before he could do anything, the blonde boy appeared behind the man and grabs the top of the man's head and jaw and snaps his neck.

Mikasa then drops to her kness, eyes and mouth wide open, her body trembling, the shock and trauma of her parents' murder are suddenly too much for her. Tears falls from her eyes as she sobs. Naruto slowly walks over to her, and kneels down in front of her. He looks at the girls face and he could tell that she is hurting bad. Naruto did the only thing he could and hugged the girl. The girl then wraps her arms around his waist and cries into his chest.

"I'm so sorry, I was too late," whispered Naruto into her ear. Naruto didn't know why he made that promise, but he knew that it felt right.

Once the girl had stopped crying, Naruto pulls themselves apart and gave her a small genuine smile and asked "I'm Naruto, what's your name?"

"Mi-Mikasa," replied the girl as Naruto grabs a handkerchief to clean the her tears and wipes her hands of the blood.

"Okay Mikasa, we're going to go outside okay? I want you to keep your eyes on me alright," said Naruto as he didn't want the girl to see the bodies of her parents like this.

Slowly, Naruto led Mikasa outside of the house. Once outside, Naruto gives her his small water bottle from his pouch. "Here drink this," said Naruto. After drinking the water, two people arrived. One is man wearing glasses with a moustache and the other is a boy who looks to the same age as Mikasa which seems to be around 10 years of age. The boy has medium length raven hair and green eyes. Naruto had already sensed they were coming so he isn't surprised.

The man looked into the house and gasped as he quickly made his way to Naruto and Mikasa. The boy peeps into the house but quickly vomited at a nearby bush. "Eren, come here," said the man as he reaches the two kids. The boy now revealed to be Eren quickly stood beside the man.

"What happened to the Ackermans? What happened to your parents Mikasa?" asked the man. Mikasa then stood behind Naruto and holds his right sleeve as she feels a bit uneasy from the questions from the man.

Naruto seeing this, decided to answer for her. "Those three were human traffickers, they were here for Mikasa but I stopped them but I arrived too late for her parents," said Naruto as he looks away. Mikasa also looks towards the ground from hearing the explanation.

The man then asked "Mikasa is this true?" asked the man. Mikasa nodded in reply. The man couldn't believe it, a boy had just killed three men on his own.

"….My name's Grisha Yeager and this is my son Eren, do you remember me Mikasa? I'm a good friend of your parents. I used to come here to do check-ups on your family when you were little," said Dr Yeager. Mikasa nodded.

"Um Grisha-san, could you please check MIkasa for any injuries?" asked Naruto as he wanted to make sure the girl is alright. The man nodded then proceeds to check on Mikasa but the girl hides further behind Naruto and holds his right sleeve with a tight grip.

Naruto then turns to the girl and say "Mikasa, come on, let the doctor check if you for any injuries," said Naruto with a an eye smile.

"I'll be right beside you" he reassured her. Mikasa reluctantly allowed the doctor to check on her.

'No physical injuries but no doubt she has some psychological issues after watching her parents killed in front of her eyes.' thought Grisha.

"She's fine and I forgot to ask, what's your name young man?" asked Mr Yeager.

"Oh, it's Uzumaki Naruto!" said Naruto as he rubs his left hand over the back of neck in embarrassment of forgetting to introduce himself earlier.

"Naruto? That's a weird surname," said Mr Yeager.

"Ouh Uzumaki is my clan's name and Naruto is mine!" replied Naruto with a nod.

'Clan? Could he be an Asian just like Mikasa and her mother's side?' thought Mr Yeager.

Naruto could feel Mikasa shivering probably due to the cold. He unwrapped his scarf and kneels down to wrap it around her neck. After trying to wrap the scarf at least decently, Naruto pulls back and rubs his right hand on the back of his head with a sheepish look as the scarf is all over the place.

"There you're all warm now!" said Naruto with a grin.

Mikasa could only stare at Naruto as she pulls up the scarf up to her nose and takes in Naruto's warmth and scent.

Mr Yeager then kneels down to face Mikasa and says "Mikasa, we better get going before the Military Police gets here, from now on you're going to stay with me and my family. My wife always wanted a daughter so I know she'll be happy to have you and Eren will be your younger brother."

Mikasa was tempted to go but she didn't hear anything about where Naruto will be going.

"What about Naruto?" asked Mikasa. Mr Yeager expected this as he can already see Mikasa getting attached to Naruto.

"Naruto, young man is it all right if you accompany us?" asked Dr Yeager.

Naruto is about to say no to Mr Yeager but Mikasa then tugs on Naruto's sleeve and faces Mr Yeager and asked "Can he come with me?"

Naruto seeing Mikasa's eyes could see that she really wants him to be there so he reluctantly agrees.

Mr Yeager nods at her with a smile and the four of them made their way towards Shiganshina District where the Yeager family stays at. Throughout the journey, the four of them were walking in comfortable silence, Eren is walking beside his father while occasionally looking at Naruto and Mikasa behind them while Mikasa is walking closely beside Naruto still holding his sleeve.

Naruto knowing that Mikasa is depending on him, he intertwines his hand with her smooth hands and gives an eye smile. Mikasa when felt her hands being held could only gasp as she turns towards her saviour. When she saw the eye smile he gave her, she could only bury her head deeper into the scarf but Naruto could see it in her eyes, she feels safe.

Shigashina District

The group made it to a house a good distance away from the inner gate of Wall Maria. Upon entering they were greeted by a woman that has light-colored eyes and dark hair that is rather long and tied loosely to her right shoulder. Mr Yeager then introduced the Naruto and Mikasa to the woman.

"Hi!, I'm Carla Yeager, Grisha's wife and Eren's mother. You must be Mikasa! You've grown up so much! Where are your parents? Who is this young man Grisha?" said Carla as she fired questions left right and center.

Grisha then whispers to Carla what had happened. Carla's eyes were wide and she quickly pulls in Mikasa for a hug. After comforting Mikasa, Carla turns towards Naruto.

"Hi Carla-san, my name is Naruto," said Naruto with a smile.

'He doesn't look like a criminal,' thought Carla.

"Thank you so much Naruto for saving Mikasa!" says Carla with a grateful look.

Naruto with a serious face simply said "It was the right thing to do."

Carla was surprised by the seriousness of his answer but decided to move on.

"Come here Naruto, Mikasa, I'll get you two something to eat," said Carla as she prepares a quick meal for the two.

After dinner, Grisha asks Naruto some questions.

"So Naruto, where do you live? I hope your parents don't mind you staying out this late?" asks Grisha.

"I guess you could say I live in the farmlands alone. My parents passed on the day I was born, I've been alone for the longest time I could remember." said Naruto with a sad smile as he remembers his parents while coming up with a white lie.

"But there were people who took care of me even if we weren't related so I'm thankful for that," added Naruto as all of them listened in on what Naruto is sharing.

"Where are they now?" asked Eren.

"They've all passed on now," answered Naruto.

Everyone was quiet from the sombre mood Naruto's sharing has set.

"Well, thank you everyone but I think I should get going," said Naruto as he decided that he has overstayed his welcome.

Mikasa quickly grabs his left sleeve tightly. Naruto turned towards Mikasa and sees her eyes watering. Naruto doesn't want her to feel awful but he definitely can't impose himself further on the Yeager household.

"Take me with you," said Mikasa with a pleading look.

"Mikasa, I can't possibly-" said Naruto but he was interrupted halfway by Mikasa.

"I'm going with you," said Mikasa with a tone of finality.

Everyone else were surprised by Mikasa's sudden firmness.

"Excuse us for a minute hehe," said Naruto as he pulled Mikasa away from the dining table and outside of the house.

Naruto kneels down with Mikasa infront of him.

"Mikasa, tell me the real reason why you would want to follow me?" asked Naruto.

Mikasa looks down at her scarf and then looks back up at Naruto and says "I want to be with you."

"Are you sure?" asked Naruto.

Mikasa nods as her reply.

"I'm sorry Mikasa, but I have to go, you have a family here now, I'm sure they'll take good care of you! Eren's now your younger brother! You'll be safer and happier here." said Naruto as he place his hands on her shoulers..

"Promise me…." said Mikasa as she looks down but the latter half of her words were too soft.

"Promise you what Mikasa?" asked Naruto.

"Promise me that I'll see you again!" said Mikasa with tears flowing down her cheeks.

Naruto remembered he still has the Shodai Hokage's necklace with him, although it was broken during the Pein attack, he was able to fix it back together, albeit the necklace's abilities are no more. The necklace consists of a cylindrical teal gem with two small bells to its sides.

Naruto pulled out the necklace from underneath his shirt and unclips it.

Naruto's hands then went behind Mikasa's head and put on the necklace for her.

"Mikasa this necklace is very important to me so I need you to hold it on for me okay? That way I can collect it back from you, I promise you that," said Naruto with an eye smile

Mikasa looks up at him and said "Thank you…"

"Mikasa, now I need you to promise me something," said Naruto.

Mikasa nods as she awaits her promise for Naruto.

"Promise me that you'll always be happy and be safe! And don't cry whenever you feel bad! Only cry whenever you're happy!" requested Naruto.

"I will I promise!" said Mikasa.

After making their promises to one another, they both return back to the dining table. Grisha and Carla had already concluded that Naruto already has persuaded Mikasa to stay with them evident by Mikasa's puffy and red eyes. Eren still confused by the situation is about to ask his question but is stopped by Carla.

After a few more minutes, they are all outside saying their goodbyes to Naruto. "Naruto know that you're always welcome here," said Carla with Grisha nodding to that.

"I appreciate that, thank you very much Grisha-san, Carla-san," said Naruto as he bows in front of them.

Naruto then turns towards Mikasa and before he could say anything, Mikasa has already wrapped her arms around his waist with her face burrowed into his stomach. Mikasa started sobbing a little.

"Now now Mikasa remember what I said earlier?" asked Naruto as he patted her upper back.

"I remember, thank you," whispered Mikasa.

Naruto then kneels down and pokes her in the forehead with his index and middle finger.

Mikasa looks up to Naruto giving her his best smile which she returns with her own.

When they pull apart, Naruto goes to Eren and says "Eren, please lookout for Mikasa okay!"

"You can count on-" Eren was interrupted by Naruto.

"On second thought, I think Mikasa will be the one to look out for you," said Naruto as he adopts his thinking pose.

Eren hearing that, glares at Naruto as he crosses his arms. Everyone is laughing at Eren's expense even Mikasa is sporting a small smile.

Naruto pats Eren on the head and gives a two-finger salute to the rest as he walks away.

"Ja ne everyone!"
