Note this is when they are 12 years old and Just saying Roxes is 15 years old but he is badass even more powerful than Minato ok just saying because they gonna fight later on in the story. Remember the teams for Naruto.
Naruto POV
I was sleeping like a baby until my brother came up into my room and whispered into my ear.
Roxes: hey Naruto wake up someone waiting for you.
Naruto: * still half asleep* who's that?
Roxes: JOHN CENA!
He yelled into my ear waking me up and giving him a sucker punch, he block the punch and went down to make breakfast. I went into the bathroom to get ready for the graduation test to become a ninja, i was excited because i will be able to show my so called Family how powerful i am but Roxes Nii told me i had to go back to the Hokage house to not raise any suspicion about me. I ate breakfast quickly and said bye to Yuuko, i had kinda like Yuuko since i was eight but she wasn't the only one i like. I teleport back into my old family house, i was in my room it look normal with some sad drawings of me and my family but with me crying in the back round. I walk out and went down stairs where i heard that Menma was going to learn the Rasengan with Naruko, Mito was gonna learn how to use her chains, jokes on Menma and Naruko Roxes Nii taught me his own version of the Rasengan. Shadow blast. ( its like lighting blade and Rasengan combined but its red,blue, and black). I didn't brother to walk over to them and eat since i already ate and didn't want ruin there little bonding time so i open the door and walk out.
Mito POV 
Mom was telling me how good i was with my chains but i kinda wanted to hurry so i could try to spend some time with Onii-san( Naruto). I look back and saw him leave but looking sad, i knew why because mom and dad never paid much attention to him and Menma and Naruko are always causing him trouble. But i realize that our birthday was    Coming up soon and we all are turning 13 years old so i ask them.
Mito: Mom when are we going to let Naruto nii come with us on our birthday?
Both mom and dad pause and look at me.
Kushina: Mito...what did you say?
Mito: i said when are we going to let Naruto nii come with us on our birthday because he never came with us or spend anytime with us.
Mom and dad look at me for a while until mom started to tear up.
Kushina POV
I had forgotten about my own son and when Mito pointed it out that Naruto didn't come with us on his birthday with his siblings and he never spend anytime with him. I started to tear up, Minato walk over me and he had the same eyes as me. Sadness and guilt. I wipe my eyes out and told Mito that we get him to join us on his birthday and will finally train him too.
Minato POV
I was sad with guilt because i never paid any attention to Naruto, then my wife told mito that he be with us on her s birthday and we will finally train him which was a good idea. We be a family again.
Menma POV
I was piss of because of That dead last weak Naruto, he will begin to train with us and I won't like it one bit. What if he gets stronger than me? I wont get the ladies and be hokage. I have to stop it by showing them how weak Naruto is.
Time skip
Naruto POV  
I arrived at the academy and sat  down next to Yuuko and Amaya since they were my best friends. Then the teacher came in and told us that the Hokage and his wife will be watching us take the exam. We took the written part first i got a 100, yuuko got a 99 as well as Amaya, and everyone else got 90 or below. Then we did the Shuriken and Kunai throwing test and the parents were watching us this time. Yuuko got 17 out of 20 as well as Amaya, Mito got 15 and Naruko got 16 while Menma got 19.
Menma: beat that loser!
He yelled at me, i walk up to the targets and in a flash i hit them all. 20 out of 20. Menma was shock and so did my parents, we then did a justu test and i past by making 3 shadow clones. Then finally there was the spar.
( we skipping to Naruto fight)
It was me Vs Menma he was like why waste his time a weakling like me, i was tick off at him for calling me a  weakling  so i called him something that will make him want to fight me.
Naruto: if  I'm such a weakling than why did i get better scores than you?
He look at me with anger and went inside the sparing circle we got into our battle  stance, when the teacher said GO! He charged right at me going for a punch but i block the punch and kick him right where the sun does not shine. He fell down in pain but got right back up.
Menma: you pay for that!
Menma then started to charge up a Rasengan and he was smileing at me, i guess he wants to get dirty so i do the same.
I hold out my right arm and black lighting appeared from it shocking everyone even the hokage and his wife. I started to focus chakra into it and a red/ blue/ black sphere started to fork on my hand fixing with the lighting.
Naruto: whats wrong? Sacred? 
Menma: SHUT UP!
He charge at me with the Rasengan and i did the same with my shadow blast, both attack collide with each other making a small crater below us. It didn't take long before his rasengan was destroyed and my shadow blast collide with his body, it blasted him back into the ground making a huge crater. Everyone had wide eyes that i was able to finish the Hokage son the one who was train by the most powerful people in the village, defeated so easily. Then everyone included me heard clapping, i turned around to see Roxes nii.
Roxes: good job Naruto! You beat him! And also manage to master the shadow blast at 25% of its power nice job!
Im proud as your older brother!
Everyone: EHHHH!?
