Naruto woke up on Thursday morning to find his room blazing with Summer sunlight; his body was well tone but very stiff sleeping on a hard mattress. He sat up quickly and looked over at his clock, it had been blocked from view by the curtains but got a glace that it was quarter to six. Seeing that he was awake, he gathered all his thoughts on the recent events, but one which didn't leave his mind was Kyubbi.

A demon was sealed inside of him and by none other than Yondaime Hokage. The real question is he, not a demon? Will the Kyubbi influence him? And why did they seal a demon inside a newborn?

Sooner or later he is going to ask Hokage about this sealing of a demon inside him anyway.

'I am up early so how about some training.'

After completing his morning routine the blond began to prepare his breakfast. That is boiling water and adding it to his cup noodles. This instant cup noodle was his favourite it had a dehydrated small piece of pork in it. It didn't taste like fresh pork but, something better than nothing.

[Strong emotions contribute to acid coming up the throat. Increasing saliva level. Please swallow the food with saliva to calm down the acid.]

'Stop saying weird shit and shut up!'

[Going into silent mode.] As the Voice died down Naruto poured him a cup of milk.

'All in order,' He said, as he clumsily fed himself. After a quiet breakfast, he left the apartment with excitement on his face.

'I still have three hours before the academy, let's train.'

Reaching the training ground Naruto took out 2 academy Kunai as he took The dragger stance, he started to perform its movements, it was the same with Hawk style. But the surprising fact was Naruto didn't feel the slightest exhaustion even after performing and even his movements were 'too fast and precise

'Hey Nano'

[Deactivate silence mode?]

'...yeah' Naruto still wasn't fully grasped the concept of the machine.

[Deactivated, Yes Master?]

'Sigh ...I understand that my movements are precise, but how in the world I'm moving so fast?'

[I have reconstructed your body, Master]

'Ah! Reconstructed, I remember you said something about it last night'

As Naruto thought back to his conversation last night, but he didn't know what it meant.

'Okay... But I didn't get it. Can you please make it easier for me to understand?"

Naruto thought as he barely got up and sat down on the ground.

[Changing language to fit the user's level.]

'Level?'

Naruto frowned as it didn't feel too good; it felt as he was insulted, but he couldn't understand fully either.

[Translation complete. Yes, Master. The nanomachines have extracted the unnecessary substances from your body and have reshaped the blood, muscles, and joints to best fit your body shape.]

'Oh, now I get it! That black thing on my body was your work.'

[Yes Master. Reconstruction has increased Master's speed and strength.]

'... wow! You are awesome Nano'

Naruto was just amassed.

[Thank you, Master]

Our Jinchuriki spent some time sprinting around the ground. Surprised that not only he was fast but even after running for half an hour he didn't feel much exhaustion. That's when Naruto heard someone's voice.

"Ha ..."

Curious as he was, he tip-toed to the nearby bushes along the side of the training ground. What he saw was leaf Shinobi be practising his katas. He was moving quickly changing his stance one after the other. It amazed Naruto.

'If only I could learn that Taijutsu' He could never learn a higher level Taijutsu until he becomes a Genin rank ninja.

[Would you like to scan The Ninjas movements?]

The blond boy opened his eyes in shock.

'Can you scan a person's movements too?'

[It is possible.]

'Then you mean you can scan that ninjas Taijutsu movements and transfer them to my head?'

[Yes, Master. And there is data of multiple martial arts techniques that I can transfer over to you at this moment.]

According to Konohagakure Shinobi standards, it's was rude to peek at or copy the training of a fellow ninja from the village. The fact that he did not gain approval from Shinobi, but he wanted to protect himself from any threat even if it was coping with Taijutsu. He had to make a choice.

'Okay. Scan it.'

[Activating the scan.]

Naruto's focus began to shake rapidly and then started to scan Ninjas movements. After staring at his movements for about thirty minutes, Nano's voice filled his head.

[Movement scan completed. Martial art is rectified after proper analysis. Beginning transfer.]

And with the jolt, the movement began to playback in Naruto's head. And soon, it was complete

[Transfer complete.]

With the slight dizziness, it was done. Naruto's smirked

This was beyond amazement.

'It's like I know all the movements at the back of my head.'

Naruto tan towards the other side of the training ground so the Shinobi could not see him.

He started to perform all the katas, his movements now matched Shinobi's movements perfectly. As Nano's voice rang in his ears again.

[Muscle analysis complete for training the movements. Will you accept the transfer to your muscles?]

'I need the muscle transfer too, but last time didn't need one right?' The boy asked curiously.

[Last Taijutsu was basic and didn't require any properly developed muscles for your movement, but you will...]

"Ugh!"

Before Nano could finish, Naruto felt pain tearing through his entire muscle. It was so intense that he couldn't even move, he slumped on the ground.

'ugh., Why?'

[Master did not train like The Ninja for a long time, so your body is not yet accustomed to the movements that your brain has learned. Only after simulating the movements and analysing the muscle development requirements you can use Taijutsu Thoroughly.]

'Okay... I think I understand. It's still hard though.'

Most terms that Nano used were not used in people of current times, which was hard to understand.

[Would you like to lower the language level to the lowest level?]

'...No, that won't be necessary. So, if I transfer the muscle development, I won't have this bad pain?' he quickly said.

[That is correct. Will you begin the transfer?]

'How long does it take?'

[Reshaping muscles will require every Nano Machine inside the body, which will take loading time.]

'Loading time? So how long will it take?'

[Approximately two hours.]

It was still early in the morning, and he still had exactly two hours before the academy starts. Naruto quickly laid down near a tree. Agreeing to muscle transfer.

[Activating muscle transfer. It will come with strong pain, so you will be put under anaesthesia.]

'Does it hurt?'

[It comes with severe pain. There have been millions of cases of fainting from the pain.]

'Should I try it without anaesthesia?'

Naruto wondered curiously.

[Will you proceed without anaesthesia?]

'...If I can't bear it, can you put me to sleep?' Naruto added. He soon realised he was not wrong in adding that last part.

[Beginning the process.]

As millions of nanomachines began moving toward his muscles, he felt ticklish.

"This doesn't seem-" And the muscle change began at once.

"UGH!" he gasped. The muscles twisted and his eyes rolled backwards at the intense pain. He couldn't scream as he knew that anyone near the training ground would hear him, but he couldn't hold back either.

"Nnnnnnggghhhhhaaaaaah..." Naruto bit his lip as he twisted in agony and almost screamed as Nano's voice rang in his head.

[Injecting anaesthesia.]

as Naruto fell asleep.

Two hours then passed by.

[Muscle transfer complete. Deactivating anaesthesia.]

With a jolt in his head, Naruto woke up from his sleep.

"Ugh!" The boy got up, panting. He remembered the extreme pain right before he was put to sleep. He did not want to feel that kind of pain anymore, which was worst than the pain when he was stabbed

"Ha... I will never try it again.'

[I warned you, Master.]

"...Yeah."

It was Naruto's choice to try it out. He then got up from the shade and walked to the centre of the ground to prepare himself to use the copied skill.

'Now it won't hurt, right?"

[Through the simulation, you now have the same muscles as the ones that practised the movements for years.]

'Good!'

Naruto prepared his stance and breezed through his katas. The power seemed to be very different from a while ago as his movements were more precise and accurate. As he stomped to move on to his next step, the ground rumbled loudly.

"Woah!"

Naruto was surprised and stopped immediately. The floor now had marks of his footstep.

"It leaves deep footprints even without Chakra."

While he was thinking about it, that's when he realised that he was late for his academy. Naruto panicked as he took off, he wanted to make a good impression today, and he already messed up.

Academy was not too far away from the training ground. But the speed at which Naruto was running made the time required even shorter.

The Academy was a huge building in Konohagakure located directly at the base of the Hokage Mountain. Where the ninjas are trained and the official ninja receives their assignments. It was founded by the Second Hokage; Tobirama Senju out of military necessity.

As the academy came into view Naruto frowned, eyeing the Hokage tower and mountain.

Naruto rushed through the corridor of the Academy. It was bustling in a few classrooms while others were quiet; hinting few of the classes had already begun.

'Fuck'

Standing outside the door to his classroom; Naruto got a nervous look. As he heard Iruka talking to his class.

'He is even done with the attendance?'

"Naruto didn't come today eit-?"

"I'm here!"

Naruto loudly busted in, surprisingly heavy wooden door. Everyone's attention was now on the said their point of view Naruto looked different, his baby fat was trimmed out of his face and he wasn't even wearing that horrible orange jumpsuit. Instead, he was wearing a grey-green shirt and grey cargo shorts.

Naruto smirked as he caught everyone eyeing him intently, especially Iruka.

"Iruka-Sensei, did you miss me? You'll whatcha looking at?"

Hearing him, everyone snapped out of their thoughts.

"Ahem, you changed."

"Is it bad?" He asked innocently

"No no! I mean a good change." Iruka said shaking his head. Without any word, Naruto quickly reserved his seat beside Shikamaru one of his friends besides Choji.

Shikamaru who was sleeping head down was now eyeing Naruto. His blond friend did look different. But asking him would only waste time as he was not sure that he would get any answers from the blond.

"Alright, Naruto. Today will be the last day of you being late or bunking the class," said Iruka

"Make sure you will not miss it, or I will get 'lectured' by Hokage-sama," said Iruka tries to remind Naruto, who is yawning continuously with a bored expression.

"Yeah-yeah... Just take it easy, Sensei, or you will never get married." Replied Naruto while teasing his teacher, which caused the whole class to Snickers.

During the three years, Naruto became more familiar with his teacher, but mostly he would tease his strict teacher about some of this stuff.

"Grr... Huft... If you just have a little bit of sincerity, I will not worry about you at all. But, to be lectured by me for three whole years and couldn't even do a simple bushin truly hurt my pride as a teacher."

"Easy, Iruka-Sensei. Actually... I also want to but..." Naruto sighed. Iruka knew that blonde gave his all in learning ninja arts, he joined the academy two years prior to his classmate, yet he failed for two years.

'Naruto... You...' Thought Iruka as he immediately felt wrong to bring up such a topic. Naruto flashed Iruka a sad smile.

"Don't worry..." said Iruka

Before Iruka could finish his sentence, "But, I think it is too troublesome to do it right Naruto?. So, teacher, why don't we just end this class and enjoy the weather in the garden. Today has good weather for laying around." Shikamaru spoke up diffusing the awkward situation.

Hearing this, Naruto felt grateful for what his friend did. Iruka sighing started with his class.

"Thank you," Naruto said softly.

"Troublesome" Naruto just chuckled at his friend's antics.

Now, he just has to wait for the practical class to show Iruka-Sensei his skills.

Authors note:

For readers who are wondering, will Naruto hide his strength? No, he will be showing his potential and won't hide anything besides the existence of nano.

No bashing! No love life in any chapter at least anytime soon and this story will revolve around Naruto, I will try and show other characters development.
