naruto pov
As soon as they finished talking I saw how they launched themselves at me to attack me I thought that Jiji would come to save me but I realized too late, he is the Hokage so he will not always be watching him because he is busy doing other things.
When they approached him he felt how they began to throw stones at him, that didn't hurt him much but later they began to beat him for which his pain increased and finally they began to cut him with kunais.
Within minutes of screaming in pain he would fall unconscious, so he stopped feeling pain.
I woke up in what looks like a sewer with many paths but I felt two presences coming from two different paths, I was a bit scared since one of the paths felt very evil while the other felt great pressure making it feel heavier, he decided go that way since at least I didn't feel ostility like the other way.
As he advanced he could feel how the pressure was increasing as he passed there was a moment when he wanted to start retreating but he heard someone tell him that if he was going to give up, so he assumed it was the one at the end of the tunnel, so with all his dedication and effort he managed to get out of the tunnel he was more tired than in his entire life but he felt that it was worth it, he was also curious about what was on the other side of the tunnel.
Coming out he would see many mountain-like rock structures only smaller and with lots of spikes in the center.

(Something like that)
He saw a man on one of the tops of a rock he was about to speak until he turned around and oh naruto could see him whole then the man jumped off the rock to land a few feet away from naruto.
Naruto felt nervous as the man had an intimidating look on his face but with all his courage he asked.
Naruto: Hi, I'm Naruto. Who are you?
He would ask a little embarrassed since he never talked to anyone just with his jiji that he was the only one who didn't treat him badly.
The man would look at Naruto as if inspecting something that was getting on Naruto's nerves since he believed that he was going to hit him.
A: I am A the third Raikage.
Naruto would be surprised that he answered him since nobody talked to him and when he spoke to them they just insulted him, but then he remembered that he said raikage so he thought he was like his jiji since he had explained that everyone who had the kage position was very strong.
Naruto: so you are like my jiji a kage.
The raikage would continue to see something that didn't bother Naruto so much knowing that he wouldn't hurt him.
A: jm who is your hehe.
Naruto: His name is Sarutobi Hiruzen.
A: a and he is the hokage right.
Naruto: that's right you know him.
A: That's right I fought him a few times.
Naruto: seriously and who is stronger.
He would say it with emotion since he knew that his jiji being the hokage was the strongest man in his village.
A: Of course I did but he beat me once.
Naruto: fence you must be very strong to have beaten jiji, by the way you know where we are.
A: We are in your mind.
Naruto would be surprised by that since he believed that he was lying but then he remembered the beating they gave him and that he just fell silent he got up ouch.
Naruto: I see and what do you do Mr. A in my mind.
A: I'm only here because the shinigami put me in your mind seeing that your life was going to be very lonely.
Naruto: and why would the shinigami put you instead of someone else?
A: That's because I'll be the one to train you to be the best ninja of them all.
Naruto when he heard that was surprised and glad to know that he would be trained by someone very strong.
Naruto: seriously you will train me.
A: That's right when you get out of your mind you will go to a training camp where I will start training you.
Naruto: okay A sensei and what will you teach me.
A: I'll teach you to be the strongest ninja and look at them all just like I look.
So he would lean back and put on the raiton no yoroi.
Naruto: great I also want to be able to do that.
A: there is still a long way to go before you can do this naruto, remember one step at a time.
Naruto: yes To sensei.
A: well when you wake up you can't tell hiruzen that you talked to me or that you entered your mind naruto.
Naruto: and why can't I.
A: You must keep it a secret from everyone that you know me, Naruto.
Naruto: well I understand that but why can't I tell him to enter my mind.
A: you see naruto come sit here next to me.
She would say it by touching the ground where he was sitting.
Naruto would sit across from A and tell him.
Naruto: ready now.
A: Naruto you know what a biju is.
Naruto: I don't just know that the kyubi is one of them.
A: well that's right the kyubi is a biju but along with it there are 8 others that start from the one tail to the nine tails which is the kyubi.
Naruto: I understand.
A: Well, Naruto, you can't kill a biju, so it has to be locked up inside a person.
Naruto: yeah.
But later he would realize that they always treated him badly and called him a devil, for which some tears would fall from his eyes and he would tell him.
Naruto: So the kyubi is locked inside me.
A: that's right naruto.
He would say it a bit sad since he reminded her a bit of one of his friends.
Naruto: So the other presence on the other path was the one that took me to the kyubi.
A: that's right, that's why you can't tell hiruzen that you entered your mind because otherwise he might think that you already talked to him kyubi.
Naruto: Okay sensei and when I'm in the training camp I'll talk to you.
A: nothing you just have to think about talking to me and you can listen to me.
Naruto: well that's fine I don't want to have to come in here all the time.
A: well naruto when you get out of your mind you will see hiruzen I want you to ask him for books on ninjutsu and mathematics along with a chakra paper.
Naruto: he's fine but if he tells me why I want him.
A: tell him that you will start studying so that when you are older you will be very strong, nothing more.
Naruto: Okay sensei see you in a few hours.
A: It's ok, to go out you just have to think about it.
He would say it with a drop falling from his head seeing that Naruto didn't know how to get out.
