I do not own naruto anime, manga or other released formats.
As Naruto began doing his secret training, and the imprint of Madara not leaving the boy alone on a single night, the effects started to show after the 1st year. He was stronger, quicker, smarter and more skilled that the average little boy his age. His "parents" could not be more surprised when a man decided to try and steal the purse of his mommy was Naruto called her. He did snatch the item in question. His mother could have stopped him easily but she figured that it would be wrong for a fully trained jounin to injure a civilian that was so desperate for money that he fall to do such low handed and despicable things. Naruto however was not a ninja and not registered as such, but he simply was not going to let some crook try and do something like that to his mommy.
He had been eating a set of dango that Mikoto bought for him for helping her carry some really heavy supplies she needed for the next class day. In truth the class were assigned into teams of 3, and they were supposed to get the item together. But the other kids in the teams were lazy, one wanted the home assignment to fail so he be moved to another team, and the other simply said that the task was too troublesome to even try. Naruto saw a sad Mikoto at the schoolyard and when he heard what the other 2 said, and that she was going to fail because of them she simply offered to help. Mitoko was surprised, I mean he was supposed to help with a job by doing the work of 2 guys at least 5 years older. How was he supposed to do that. "Shadow Clone Jutsu!" 10 Naruto clone appeared from what looked like a smoke bomb going off. Well this made the work that much easier, and since they helped her finish the work early the teacher gave them a pair of free Dango coupons.
Having eaten one stick he saw the creep take his mommy's purse. He simply took the dango stick and did yet another jutsu he learned in a dream. "Shadow Kunai Jutsu" was whispered as he did the hand signs and throw the dango stick. The second he did where there was 1 dango stick became 100, pinning the crook against a wall. He got up and looked at him with so much hate that the crook was thinking that this was a nightmare. "Steal anything from my mommy again, and you will not live to see the next day. Got it!" The crook was who it was and knew who his mom was. He simply nodded before fainting. He left the crook pinned to make sure he remembered that.
Mikoto was still seated eating her dango when Naruto casually walked in with the purse in hand. "Honestly Naruto people are going to talk about something like that. You know that you are too young to be doing that?" Naruto simply laughed and mentioned ,"Who would believe them anyways? A boy not even 4 doing jutsu and pinning a crook like that?" Mikoto had to admit that he made sense, the civilians would never believe it because it would be too incredible, and the ninja would never acknowledge it because they would see that a little boy barely going to be 4 actually did a jutsu most genin would have trouble with. The ignorance of the civilians and to keep the reputation of the academy would keep this incident from spreading.
Little did Naruto know that not all the ninja would ignore it. The Anbu Commander watched the entire thing, he had even watched Naruto train. He simply could not wait for the little boy to get to Chuunin so he could send the application to have him in Anbu. Sakumo Hakate knew talent when he saw it, and that little boy would eventually be a welcomed addition to the Anbu Corps.
His mom however was not happy one bit. What would happen if Naruto missed and ended up killing a civilian? He might have good intentions but the way to hell was paved in good intentions. Her son would be he able to cope with the shock and stress of his first kill before he was even a student? No, her little boy had to be protected. If it mean not being so relaxed with pickpockets and purse snatcher she would do it for her little boy.
The life of Naruto was like that till he reached his 6th year, and not once did he deviate from the training and not once did he complain. The other Uchiha parents felt like the little boy was pushed by the sheer responsibility of being the son of the Clan Head, others felt like the parents demanded too much from him since everyone in the clan considered them elites. But when the mother of the bully that picked on Mikoto began to try and say that his mommy was an abusive parent and that she was pushing Naruto so hard in hopes to kill him, that is when Naruto really began to show the fruits of his training. "No one and I mean no one makes fun of my mom and gets away with it!"
That was the thing that was heard, and in a matter of seconds he eyes opened to see the three tomoe in each eye, but he was really mad and the thing that scared this foolish Hyuuga woman more was that they way the eyes changed into the magenkyou stage, "How did a child have that doujutsu evolved to that point!" that was the last she said out loud. Naruto was so angry that the little boy yelled at the top of his lungs, "Tsukoyomi!" In an instant the Hyuuga was trapped in the genjutsu.
The little boy in a cold stare simply walked to the women, "You are in my world now! I control everything and when I am done with you hell will seem a vacation!" The Hyuuga knew that she was in for something bad, but how much could a little boy do. That is where a 100 kunai appeared and began to launch themselves at the woman. In a matter of seconds she was hit by all the kunai in places not deadly but painful. "That was 3 seconds. You still have 23 hours, 59 minutes, and 57 seconds to go!"She was crying and pleading, "Naruto I simply was trying to protect you! I think a little boy should enjoy their childhood! I meant no harm to you at all! I was only trying to make sure you are happy!"
Naruto looked at her, "There are ways to do things, and then there are ways to do things. Inviting a person to tea and expressing in a civil manner your concerns about how someone is raising their kid is one. No parent is perfect, there is no manual to raise children. But no you decided to humiliate my mother, like your good for nothing son!"
The lady knew nothing about the bullying her child had done. Naruto stopped the punishment just to tell her every single incident her child had been involved in, the pain, humiliation, abuse he inflicted on his fellow academy students.
By the time he finished, the things he told her hurt a thousand times worse than the kunai ever did, and as she cried she simply asked, "Do you not want to play Naruto? Do you not want to have friends? Do you think your childhood is normal?" He simply looked, "If you promise to take care of your child's bullying, and decide to talk to my mom in a respectful civilized manner. But be warned that if you don't do something about the bullying, and decide to do something like this to my mother yourself or with the help of someone else.. you will be back here and no manner of pleading will stop the time that you have left this is just suspended and give you a chance. Am I Clear?"
The woman felt like she was at Anbu torture and interrogation. She was in a great deal of pain, bleeding and crying and between sobs she promised that she would do it, but for Naruto to forgive her. As the last word was spoken the genjutsu broke and she did not have a mark on her, tears were seen but no injury. Naruto looked at his mother after deactivating his doujutsu and told her that his mommy was going to be alright. She cried and hugged Naruto. Little Naruto had tried to defend his mom and used a high level genjutsu. One the one side she was worried about her son, but deep down where she did not even notice she was extremely proud.
This one incident did make it to the Hokage and the Anbu Commander, and they both decided that if he could use the Magenkyou Sharingan then he needed to begin training in the academy immediately. In the academy he would learn what can, and what should not be done and to learn some limits in the use of force. This was to protect the civilians that due to their ignorance they might do something wrong against his family, and if someone injured his mother their would be payment in blood. They both would not be surprised, Naruto would defend his family to the point of actually killing someone, and with his doujutsu to that level he could kill a squad of genin faster than it takes them to say Ramen.
So was the day that Naruto was admitted to the Academy and Mitoko still had a few more years to go, She was happy since Naruto would be going to the academy. They could walk to school, eat lunch, help him with class stuff and walk home together. Mitoko was really happy about that.
