Chapter one: Beginning

Somewhere in the farmlands of wall Maria.

A ten-year-old boy could be seen crouching behind a bush as he eyed the two hares that were grazing the small patch of grass on the forest clearing. In his hands were two throwing knives ready to be thrown at the two hares to kill them. He had golden blonde hair with dark roots, mixed with some red hair and two bangs framed either side of his face. He had slightly tanned skin. He was quite tall for his age and he had an athletic build. He wore a dark green shirt and blue shorts which provided perfect camouflage for him. He also wore a green crystal necklace around his neck. His bluish purple eyes were narrowed as he inched closer to the unsuspecting hares. His footsteps were deft, without a single noise, showing that he was a skilled hunter, trained since he was little.

In moments, he was in position, his arms tensed taking aim at the two poor animals.

"NARUTO!" The voice startled both him and the hares. Sensing danger the hares tried to dash away from the clearing into the forest only for two throwing knives to impale them with such force that they skidded across the forest floor before coming to a stop, dead.

Naruto turned his head away from his recent kill to look at the new arrival with an annoyed look on his face.

"What the heck Mikasa!. You almost made me miss my shots!" He said in an annoyed tone.

" he hehe … sorry" The sheepish tone of her voice did not match the small grin on her face. He instantly knew she did that on purpose to annoy him. Again.

This had become a game of sort between the two of them, where they will try to get under each other's skin.

The now named Mikasa appeared to be the same age as Naruto. She had shining black hair, pale creamy skin, and bright black eyes. She wore a full sleeve shirt and black skirt which reached up to her knees. She also wore a necklace identical to the one he had. He gave that to her as a present for her birthday last year.

She smirked knowing that she managed to annoy him, although she was surprised that he still managed to hit both hares while they were in motion. It showed just how good he is at throwing projectiles. But that is to be expected, considering he was trained by his grandpa in the art of hunting from a very young age. She let out a sad sigh when she thought about his grandpa. His grandpa was the one who raised him since he was an infant. She still remembered how devastated he was when his grandfather died two years ago. And since then he was living at her house. Even though she knew that he was an experienced hunter and could take care of himself, she could not help but worry about him whenever he ventured into the forest for his usual morning hunt. He is her first and only friend after all. And they were both of Asian descent. Just another thing they had in common. Also, she has a crush on him, although she would never admit it.

She watched as he went to pick up the hares. For the past two years, he had been teaching her how to throw knives and how to hunt as well. And she was surprised to find that she was a natural at it. Hunting and throwing knives came naturally to her much to her friend's shock. Although she was not at his level of proficiency, she was proud to say she was very good at it.

Soon he came over to her, muttering something about annoying best friends.

" Here, carry this back home." He gave one of the hares for her to carry and started walking home.

"Okay!" she chirped happily as she took the hare from his hand.

With that, they began to make their way back home through the thick forest. It was a few minutes before Naruto decided to ask something

"Sooo... Mikasa, what did your mom cook for breakfast today?"

She just shrugged, " Just some vegetables and cereals which are really healthy" She replied with a slight smile knowing that he doesn't like vegetables. Honestly, she couldn't understand his obsession with meat. It's not like meat is the only source of nutrients.

"Whaaat?" He whined in a pitiful tone. "Why can't she make some meat. It's not like there is a shortage of meat or anything"

"Oh, stop your whining Naruto." She chided him lightly

"You can't eat meat all the time. you have to eat other foods as well." She turned around as her face scrunched in confusion "Why do you obsess over meat anyway?"

Naruto got a smug look on his face as rolled up his sleeves and showed her his biceps, " You see that!. How do you think I got these things?. Its all because of the countless amount of meat I ate."

Mikasa just rolled her eyes. she couldn't tell if he was just joking or being serious.'Does he seriously think he got those by eating meat' she sighed and decided to just drop the subject, as they continued on their way back home in silence.

Turning her head towards him she frowned when she saw the unusually serious expression on his face.

"What's wrong Naruto?"

He hesitated for a second, not knowing how she will react because the last time he told her about this, she did not react well. He sighed and decided to be honest with her.

"It's just…. Well… I am ten years old now. In two years I will be eligible to join the training cor-"

He didn't even get a chance to finish his sentence before she yelled, "NO, YOU WILL NOT JOIN THE TRAINING CORPS OR THE SCOUTS!"

Mikasa was angry now. She did not want him to join the scouts. she knew how a lot of scouts died each time they went outside the walls. She did not want him to die by becoming titan food. The mere thought of him not being there in her life made her blood freeze in her veins. No, She would not allow him to join the scouts.

Naruto was slightly taken aback by the amount of anger in her voice. But he was also touched that she cared for his safety this much. She was his best friend after all.
But he was not going to back down this time.

"Mikasa.." he started with a firm tone. "You know I can't do that. It was my grandfather's last wish before he died. What kind of grandson would I be if I can't even fulfill his last wish? Also, I really want to see what is outside those walls that are keeping us trapped for hundreds of years"

She lowered her head and turned away as she cursed his grandfather for planting those thoughts in his mind. she was also frustrated that she couldn't counter his argument.

Naruto sighed as he saw Mikasa turn away. He knew she did not like his decision. He walked up to her, before taking her hands into his and giving a slight squeeze.

"Mikasa, look at me." He reached and turned her head towards him as he looked her in the eye.

" I know you worry about me Mikasa, and honestly I am quite touched by that. But this is something that I have to do. You can't change my mind on this one Mikasa"

She could only sigh and nod, she knew Naruto could be quite stubborn when he wanted to be. she decided to drop the subject …..for now.

"Come on, let's not think about it right now. Besides, I can't wait to pull another prank on your father today," he said with a devious grin on his face, causing her to giggle.

Seeing her father getting pranked by Naruto every day was hilarious. With that, she began to follow him to their house.

Mikasa's mother was busy preparing breakfast. Her husband was sitting on a couch at a corner polishing his gun. she was waiting for Mikasa to arrive with the final member of their household, Naruto. She smiled softly thinking about the boy. He just seemed to have so much energy, he just couldn't sit still for a minute. He spent most of his time running around doing something or plotting to prank her husband. She giggled when she thought about all the weird facial expression her husband make whenever he got pranked.

Mr. Ackerman raised an eyebrow seeing his wife giggle, " what's funny Maya?"

"Oh, nothing Renly. Just thinking about the face you would make when you get pranked by Naruto"

A tick mark appeared on his head, " I swear, one of these days I am going to get him back for all the times he made me look like a fool." He grumbled as he thought about all the times the blond menace had pranked him.

Maya just stared back at him with a dull look on her face, "Yeaaaah…. Right."

Getting irritated at his wife's lack of confidence his skills to prank that brat back, he scoffed, " You think I can't do It?. The brat only pranked me because I let him to. but he won't be able to make me fall for his stupid pranks anymore. Also, Mikasa has been acting rather close to him. That brat is already trying to steal my Precious daughter's heart. He needs to be thought a lesson."

Maya's head snapped back at him with a surprised look on her face.

"What? You thought I wouldn't notice the way Mikasa acts around him?"

She looked at him with a deadpan expression, " No…. I thought you were too dense to see that" causing him to face fault before he quickly picked himself up and slightly glared at her

"I am not dense Maya-chan" he bit out. 'That brat is rubbing off on Maya-chan too. I must teach him a lesson before he corrupts my lovely wife and daughter' a chibi Renly thought inside his mind. But his wife was not done yet.

" Besides, I don't mind Mikasa and Naruto being together," she said. Upon seeing the expression of disbelief on Renly's face," Come on, don't act like an overprotective father right now Renly. You and I both know that he will never do anything to hurt her."

Renly grumbled and nodded knowing what she said was true. But that doesn't mean that his unofficial rivalry with Naruto is over yet. He walked back to his couch, his look an expression of intense concentration, as he began to plot his revenge against Naruto

Maya smiled and rolled her eyes as he saw his expression. She knew exactly what was going through his mind, although she doubted his master plan would succeed. Ever.

It was a few minutes before the front door burst open and Naruto entered followed closely by Mikasa. He had a huge smile on his face.

"YO, OLD MAN!", he shouted with a huge grin on his face.

"I AM NOT OLD, BRAT!", as he got up from his couch.

"You sure do look old to me. And your instincts have dulled to the level of a five-year-old. I mean you got your hair dyed pink one time and didn't even realize it. You even went into town with that horrible hair for god's sake. How a lovely, beautiful and smart lady like Maya ever fell for you is a mystery I am still trying to figure out. " As he sent a charming smile towards Maya, causing her to giggle.

" Flatterer"

" I do try, " he said with an elaborate bow.

Renly's eye twitched furiously as he watched the blonde in front of him

" . " he bit out.

Naruto looked at him with a raised eyebrow as he folded his arm over his chest.

"Ok, Then what about that ti- "

" Okay, okay I get. you got me more times than I could count. But you better watch your back kid, because I am going to launch my counter-attack soon." He said as he stomped his way out to skin whatever Naruto had hunt today while grumbling about annoying blond brats. Although he couldn't help but let out a small smile on his face. He had to admit the brat had made their lives far more pleasant while living here. His daughter seemed happier, his wife was more cheerful as well. He himself had come to consider the boy as his own son.

Maya watched her husband leave before turning to the two kids and told them to go wash themselves so that they could eat breakfast. They complied and returned after few minutes looking fresh. Breakfast was uneventful. Apart from Naruto whining about eating vegetables and Mikasa and Maya scolding him, nothing really happened during breakfast. Everyone had their fill. Soon it was close to noon. Renly was reading some book. While Maya was teaching Mikasa how to knit.

Eventually Getting bored of just sitting around and doing nothing Naruto told them that he was going out for a bit, but would return before noon. Maya looked up to see him, " Ok, but make sure to be careful and return soon. will be visiting us for dinner and he said he will be bringing his son with him"

Naruto nodded his head before he waved Mikasa goodbye and dashed into the forest.

It was sometime before he reached a secluded area in the forest. He reached the base of a big tree before settling in a meditative pose. He calmed his breathing as his body became absolutely still. He began to concentrate on himself, as he tried to reach the elusive energy that his grandfather told him about. He had been shocked when his grandfather told him that he and Mikasa descended from an ancient bloodline who wielded some strange power called chakra. Using which his ancestors were able to wield the very elements themselves. He also told him that both Mikasa and he were the last of that bloodline. He admitted that the secrets of how to wield chakra were lost a long time ago and that he himself had not succeeded in unlocking his own chakra. He also gave him three scrolls, which neither he nor his grandpa were able to open.

He stayed like that for twenty minutes before giving a frustrated sigh. It was another failed attempt. He was beginning to think what his grandfather had told him was a just a fantasy story. But that would not explain the existence of those scrolls. Sighing again he looked up to see the sun. It was close to noon. ' I better get going before Maya-san begins to get worried.' with that, he jumped to his feet and began making his way back home.

Little did he know that the events of that day will change his life forever.

Somewhere near the Ackerman residence

Two figures could be seen walking at a sedate pace towards the Ackerman residence. One was a fairly tall middle-aged man with black hair and a thin beard. He wore a gray suit with black vest and a white shirt. He wore round was also carrying a briefcase which contained all his medical equipment. His name was Grisha Yeager. On his left was a ten-year-old boy with brown hair and Gray eyes. He wore a green shirt and brown trousers. He also wore a black scarf around his neck. His name was Eren Yeager.

Grisha looked at his son, " Eren you are going to meet two kids your age Mikasa and Naruto at 's house."

" Mikasa? Naruto?" Eren asked in an uninterested tone.

" That's right, there aren't many children your age here, so try to get along with them."

" Okay, but that will depend on their attitude."

" Eren….. you will never make a friend with your attitude." He said as they reached the Ackerman residence.

Grisha and Eren climbed the stairs before knocking on the front door. Getting no response after trying a few more times, Grisha slowly slid the door open.

" - " his voice died in his own throat as he saw the horrible sight in front of him.

Hearing a gasp he turned around to look at Eren frozen in place, with a look of horror on his as he saw Mr& lying in a pool of their own blood.

Quickly regaining his bearings he rushed over to their bodies to check for any pulse. Sensing no pulse he sighed before noticing that Naruto and Mikasa were not there.

Quickly turning around, " Eren, Is there a little boy and girl nearby?"

Coming out of his shock, " N-no…There is no one here." he stuttered out.

He walked over to Eren, putting a hand on his shoulder, " Look Even I am going to call the police and request an investigation. You wait for me downstairs. Okay?" he said in a reassuring tone. Seeing him nod. he rushed out to call the police.

With Naruto

Naruto was returning home after his short trip into the forest. For some reason, he had an uneasy feeling with each step he took towards his home. He could feel it in his bones that something was going to happen. His breathing was slightly labored from the anxiety as neared his home. As soon as his house came into view he froze in his track. The deep dread that had been forming in his stomach increased. 'That smell…' he knew that smell very well. It was the smell of blood. He could see the door was slightly open. Without a second thought, he dashed towards the door before slamming it open. And what he saw there would forever haunt him in his deepest and darkest nightmares. The two people that he considered as his own father and mother were lying there dead. He saw the look of shock and despair on their faces. Their eyes once filled with warmth and love now stared at him lifeless. He stumbled back, his breathing became labored as his knees gave out under him. Tears began to form in his eyes. They were all dead. Maya, Renly, and Mikasa….He froze.
It took a moment for him to realize that she was not present. A small glimmer of hope was born in his heart, as he prayed all gods that she was still safe. Before his expression became one of Intense hatred and Malice. He could feel the hatred burning in his heart, that promised anyone that stood in his way a horrible death. He will save Mikasa and he will kill those who killed his family. With vengeance in his heart, he dashed into the forest with unimaginable speeds.

With Mikasa

Mikasa shivered as she felt the cold wind brush against her skin. she was cold and hurt. Lying on a floor with her hands tied behind her back, she felt completely broken despite having no physical injuries. Just a few hours ago her life had been perfect. But now, It was completely destroyed. Her father and mother were both dead. she didn't know whether she would see Naruto ever again. She couldn't even cry. she could vaguely hear the four people in the cabin talking about selling her at the underground auction. But she didn't care. There is no place for her to return to. She had no will to live anymore.

With Naruto

Naruto was dashing through the forest at unimaginable speeds. It didn't take long for him to detect the trail left behind by the killers. From what he could assume there were five men the trail, he soon came upon a small cabin. His eyes narrowed. He knew the murderers were inside. As he got ready to make his move a slight movement caught his attention as he saw a boy his age slowly enter the cabin with a knife behind his back. Not wasting any time he followed the boy in silence.

Eren was scared as he entered the cabin. He slowly made his way to the front door before opening it. His eyes widened when he saw a small girl tied there lying on the floor motionless. His entrance gained the attention of the three people occupying the room.

One of the guys rushed to him as he tried to back away, " Not so fast kiddo! How did you find out about this place?" the dangerous tone in his voice made him shiver.

"H-huh.I... The forest. I got lost in the forest ….. and found this place."

"Aaaah, do you think we would believe such a poor lie kid." as he crouched down to Eren's level.

SWISH

The assailant dropped down clutching his throat as Eren drove his knife into his throat in a single fluid motion. "Like I care if you believe me or not, scum," he said in an emotionless voice.

The two remaining occupants screamed as they rushed at Eren to end his life.

When Naruto saw the two assailants charge at the strange boy, he knew he had to make his move now. In one fluid motion, he grabbed two throwing knives and let them fly with pinpoint accuracy.

SWISH

SWISH

Two throwing knives were thrown at such speed that it impaled the two assailants right in the throat and completely stopped their forward momentum. They fell to the ground, dead.

Without missing a single beat he rushed into the room and headed straight to Mikasa.
Their eyes met for a second as she gasped.

" N-naruto?" She whispered in shock and relief.

He dashed forward, quickly getting his hunting knife, cutting the rope binding her arms and hugged her to his chest.

"Mikasa," he whispered in relief seeing her still alive.

It took a moment for her to realize what happened before she hugged him back with all her strength. It felt like a dam had broken as she finally let her tears fall. All her pain and sorrow came forth in a heart-wrenching cry as she sobbed into his chest. Naruto too finally let his tears fall, as he held her tight.

Snifling she looked at him with teary eyes "Naruto, Mom and Dad…."

"I know Mikasa. But I am here now. It's gonna be okay. I won't leave your side. okay?" He rubbed her back in a soothing manner. Seeing her shaky nod, he turned towards the boy who was watching them silently.

" You two must be Naruto and Mikasa. I am Eren, 's son…" He was soon interrupted by the sound of footsteps coming their way.

Naruto's head snapped in the direction of the door, before a foot smashed right above his left eye, smashing him into the wall. He cursed himself for forgetting that there were five people involved in the first place as he clutched his bleeding head in pain.

He could hear Mikasa shout his name as he stumbled back to his feet. Blood was flowing from the cut on his left eyebrow. He stumbled around trying to regain his bearing before his head was grabbed and smashed into the wall once again.

"YOU KILLED MY FRIENDS DIDN'T YOU! " The assailant shouted in rage as he lifted him by his throat and started to strangle him.

Naruto choked. He tried fighting back, but It was useless. He was too weak from getting his head smashed into a wall. All he could see was the blurry image of his soon to be killer. He struggled helplessly, but It was no use. He could feel himself slowly losing consciousness. He could vaguely see Eren was in a similar position to him as he shouted at Mikasa to fight.

Mikasa.

That single thought stopped him from giving up. He was the only family she had left. Her mother is dead, her father is dead, and she had no one left except him. He could not and would not leave her alone by dying here.

"AAHHHHHHHHHHHH…," he shouted, as blood from his is wound covered his entire face.

And then it finally happened. The moment he had been waiting, for almost four years. Power. Like a raging fire, it flowed through his veins untamed. It was unlike anything he had ever felt. He felt like he could take on the entire world right now. The world seemed to slow down around him. He could see and feel everything with utmost clarity. He felt strength rushing back to his body. Above all, he felt warm.

A single thought entered his mind.

'Chakra'

His fists tightened around his attacker's wrist completely shattering it in the process. The assailant screamed as he dropped Naruto to the floor.

Landing deftly on his feet, without missing a single beat, he spun around and kicked with all his might.

The sickening sound of bone breaking could be heard as the force of his kick literally broke his assailant's shin in two.

"AHHHHHHHHHHH..," The blood-curdling scream could be heard around the room. But Naruto was not finished. His fist soon found the face of his enemy as he broke his jaw and nose.

" DIE. YOU FUCKING SCUM, DIE."

"THIS IS WHAT YOU DESERVE, FOR KILLING MY FAMILY." He shouted as he continued to pound his face mercilessly. He continued to pound him until he let all his rage and hatred out of his system.

Breathing heavily, he stood up to see that Mikasa had killed the guy who was strangling Eren. He could feel a strange power radiating from Mikasa. He realized that she had unlocked her chakra as well. Walking up to her he draped his arm around her as she leaned on his side. The day's events finally catching up to her. He knew she won't be the same after this. But he would be strong for her. He would become the pillar that she could rely on when she needed the most. That is a promise of a lifetime.

It was not long before Grisha came rushing with the police force. He finally let his body relax knowing they would be safe now.

The police were shocked to see the brutal sight in front of them. " Two guys stabbed right through the throat, one slashed across the throat, one stabbed from behind straight to the heart and one guy turned into an unrecognizable pulp. And this is the work of …these kids" One officer said in a fearful tone.

Dr. Yeager was scolding Eren for being reckless and willing to throw away his life so easily. But for both Mikasa and Naruto, Eren had earned their respect and eternal gratitude.

Dr. Yeager soon turned his attention to Naruto and Mikasa. Seeing his still bleeding eyebrow he cleaned the wound before stitching the wound close.

Soon night came and everyone was both mentally and physically exhausted from the day's events. It was decided that Both Naruto and Miksa would be staying at 's house.

Grisha saw the faces of the three kids standing before him. They had seen and done things that would scar them for the rest of their lives. He sighed sadly knowing that it would take some time for the kids to get over this incident. Even then he knew they could never be the same again. With that, he began leading them to shiganshina.
