After Soren's battle with Kakashi, Soren, Kakashi, and the 3rd Hokage all went back to the Hokage's office, and Soren was presented with a set of Jonin Clothes, as well as an ID that stated he was a certified Jonin of the Hidden Leaf. Soren then left the Hokage's office after getting some important information, as well as the information on how to use the Shadow Clone Jutsu from the 3rd himself, and went home to practice the technique, and when Naruto saw Soren practicing a new jutsu, he tried to stay hidden as to try and practice it himself.
[...You know, it's not nice to spy on others, how do you think I would feel if I had to go pick you up for peeping on the women's changing rooms again]: soren
[Aww!... I thought I did well to hide my presence… And it's not my fault one of the Hyuga clan members decided to scan the room before she began changing]: naruto
[That's the problem… You got caught]: soren
[Hey!... There is no way to escape the eyes of the Hyuga Clan!]: naruto
[Hehe… That's where you're wrong you brother… There is only one way to escape the eyes of a Hyuga Clan member]: soren
[How is that Nii-chan!?]: naruto
[Simple!... Transform!]: soren
When Soren said that, a puff a White smoke surrounded Soren, and once it disappeared, a voluptuous figure of Soren appeared, while wearing the same clothes that Soren was wearing before he transformed.
[Make them see you as one of them, and join them directly]: soren
Soren had noticed that during his time pretending to be a young child, he had grown some childish tendencies, and it only made Naruto become more and more childish and perverted.
'Please let my actions go by and not affect him too much': soren
Soren began praying to whatever God was incharge of the Narutoverse, but then he remembered that he probably scared off that God when he entered. After Soren's teaching moments, a few months had passed, and Naruto was now old enough to join the academy, and on the day of the initiation, Soren was there to be his guardian, and make Naruto feel just a little more normal than he would have with nobody there for him. And while other parents were arriving with their children, Soren began to hear some murmurs from some of the parents whispering between each other, and what he heard made his switch flip.
[There's that boy… The cursed one with the Fox sealed inside him]: random parents
Soren told Naruto to sit on the swing set for a second, and quickly disappeared from his spot, only to reappear behind the still gossiping parents, and began to speak in a cold tone.
[It is forbidden to speak about that incident, and you know the consequence for breaking that rule right?]: soren
The parents heard this and quickly turned towards the voice, and when they saw someone who appeared to be 8 years in age wearing a Jonin outfit, they got scared, as this was the new Jonin who had taken on 3 S-Rank missions all by himself, and he just heard them speaking about the forbidden secret.
[Please!... Let us live! Our son still needs us in his life!... Well do anything, just forgive our crime this once!]: scared parent
[Your child won't make it in the Ninja world, pull him out, and never bring him back to this academy… You will also be stripped of your title of Ninja if you are registered]: soren
Soren spoke his words and scared the family who immediately followed his words and left the academy with their child, as well as relinquished the title of Ninja if they held it, due to fear. Soren had no right to remove their right to be a Ninja, but due to the fear he can induce, anyone will give up on whatever Soren wants them to give up on, and once Soren saw the family leave, he reappeared back to Naruto's side, and saw him trying to talk with a boy who had Black hair tied up into a ponytail, but it wasn't long enough to reach down his back. The boy had a look of laziness on his face, and made Soren remember the lazy boy of Naruto's class who despite being lazy, was actually one of the smartest kids in the class when it came to strategic planning.
[Who's your friend Naruto?]: soren
Soren began walking up to both Naruto and the boy he remembered to be Shikamaru from the Naruto Anime.
[Nii-chan!... This is Shikamaru, he is from the Nara Clan]: naruto
[The Nara Clan?... Quite the background you got for yourself Shikamaru]: soren
[I know… What a drag!]: shikamaru
[So, are you guys going to be in the same class as each other?]: soren
[Yeah!... This is Shikamaru's first year as well Nii-chan]: naruto
[Good!... I hope you can be a good friend to my little brother Shikamaru-kun… Anyway, Naruto, I will be going out on a few missions for a while, so I need you to be a model student while I'm gone, okay?]: soren
[Okay Nii-chan!... Come one Shikamaru!]: naruto
Naruto then began trying to lead Shikamaru into the academy building, while Soren went to the Hokage's office to collect a bunch of missions to do. Soren would take missions to make up for his missing time, and would do it like this, Soren gets a bunch of missions assigned to him like reconnicense, and then he would send Shadow Clones to do them as a slow pace, while he would enter his Inner World and spend time with his family. Today, Soren entered his Inner World while his Clones did the missions, and was confronted by his family, as they wanted to come out and explore the world, and not for a few hours, but for good.
[I can do this, but you cannot live in the village until I put together backstories and information for you… I also cannot claim that I know you as I have been integrated into the Uchiha family, and haven't been there since the fight with the Kyuubi]: soren
When Soren spoke about the situation, Misha spoke up with a resolution to the problem.
[Then why doesn't Husband create his own Village?... Misha thinks that's the best way to solve our problem]: misha
Soren realized he never thought about this option as he had always stayed in Konoha to protect Naruto until he felt Naruto would be safe on his own.
[Then I will make a Hidden Village… Who wants to be the Kage of the village?]: soren
[Dad, won't you be the Kage?]: zeno
[I could, but I am affiliated with Konoha, so I can't take control over the village, only run it from the shadows… But Zeno, you could be the Kage]: soren
[... Then I will do so, but only until you can take over]: zeno
[That's fine… Anyway, I can stay here for a few years, and leave when I get the information from my clones about the completion of their missions]: soren
Soren then spent some time inside his Inner World, and came up with some designs for his Hidden Village, and felt that it also needed an appropriate name, and what he came up with was genius.
[My village will be the Hidden Dragon Village, the Village Hidden by a Dragon]: soren
Soren then left his Inner World, and began creating the Village, and using all sorts of arrays to hide it from anyone not welcome, and once it was complete, it looked just like Konoha, but in a different layout, as well as no mountain rage behind the Kage's tower. Soren then called out his family, and introduced them to what would now be known as Fumetsugakure, and made Zeno the First Fushikage, Soren then explained that Fushi was a shortened version for the term Immortal, while Fumetsu was the longer version. Soon, a couple weeks passed in the newly constructed village, and Soren got everyone accustomed to it, and once Soren collected the information from all his Clones, he made his way back to Konoha while leaving his family to get used to the village along with some of the Sect members who wanted to see a new world.
[Halt!... ID please]: konoha guard
Soren showed his Jonin ID to someone who was presumed to be new to guard duty, and when the guard saw Soren was a Jonin, he quickly let Soren pass through, and Soren entered the Hokage tower, and entered the 3rd's office to report on the 8 missions he completed for scouting and reconnaissance. Soren then collected his rewards, and left off towards the home he shared with Naruto, and seeing that the time was still around the time Naruto was in school, he began to clean up the mess that Naruto made him over the month or 2 he was gone.
[I will need to teach him to clean up after himself soon… If I don't I will be stuck doing house work for the rest of my time here]: soren
Soon, 6 years had passed, and it was Naruto's graduation day, and because Soren taught Naruto how to better control his Chakra, he was able to use the Clone technique that always eluded him. Soren noticed that Mizuki, Naruto's sub teacher continued to shoot hateful glares towards Naruto every second he got, and on graduation day, Naruto told Soren that Mizuki asked him to steal the Forbidden scroll of Sealing, and when Soren heard this, he didn't bother to report it, but instead transformed into Naruto and stole it himself, and when Mizuki met Soren in the woods, Soren killed him immediately before returning the scroll before anyone noticed it was gone.
[So, Naruto… Who is your Sensei?]: soren
Soren was hoping that Kakashi would still be assigned to Naruto's team, as well as Sasuke and Sakura as his teammates.
[I got a real dumb one… His name is Kakashi, and he even fell for the oldest prank in the book, the Eraser in the door prank… Can you see if the Old man can make you our Sensei instead, Nii-chan?]: naruto
[Hehe, I know I'm great, but I am not registered as a teacher… But for you, I'll see what I can do]: soren
Soren didn't plan on changing Naruto's teacher, but join him instead, as a sub teacher like Yamato did later on in the series. The next day came by, and Soren woke up to see Naruto leaving the house with no breakfast, and thought not to interrupt greatness in progress, and went straight to the Hokage's office to see the 3rd. Soren then begged the 3rd to let him be a sub teacher to Kakashi's team if they pass, and after a few moments of thinking, the 3rd decided to agree, and Soren left the office to go watch Kakashi's trial for Naruto and his group. Soren then watched as everything played out just like the Anime, with Naruto trying to charge Kakashi before he said start, and Sasuke being the solo type badass who felt he was above everyone else, while Sakura was fawning over Sasuke every second she got, even during battle, and all of this ended up with them not getting a bell. Kakashi then decided to give them another chance after lunch, and tied Naruto to the pole for not listening and trying to eat before everyone else, and Kakashi stated that Naruto eats nothing or there will be consequences, and just like the Anime, Naruto was fed by both Sasuke and Sakura, and Kakashi showed up looking angry, but in the end passed them, and when that happened Soren appeared and spoke up.
[Great job guys!... You passed the ever so cold Kakshi's test, that nobody has ever passed before, and are now fully fledged Genin's]: soren
[Nii-san!?... You were here the whole time?]: naruto
[Nii-san!?]: sasuke/sakura
[Yeah, Soren Nii-san is my brother, but not by blood… But I don't care as he has been with me ever since I was a baby]: naruto
When Sasuke and Sakura looked back towards Soren, they noticed he was a Jonin, as well being only around 3 years older than them making him 15 or 16 years old.
'Hmph… He might be an idiot just like Naruto': sasuke
'He's sooo hot!... Just like Sasuke': sakura
[So why are you here Nii-san?... Did something happen?]: naruto
[Yes, I have been approved to be your sub teacher, and will be working with Kakashi as your teacher until you guys take on your own teams]: soren
Soren then walked back with Kakashi back to the Hokage's office after giving a substantial amount of money to Naruto so he could go take Sasuke and Sakura out to eat as to deepen their friendship. Soren and Kakashi then stood in line and waited for everyone's report on who passed and who didn't, and just like the Anime, Team's 7, 8, and 10 passed, and officially became Genin's. Soren then followed Kakashi out of the office, and went to meet up with Naruto, Sasuke, and Sakura at a food stand, and when Naruto saw Soren, he ran over to hug him, as he was happy to finally be a Ninja like Soren.
[So, Nii-san, Kakashi Sensei… What's our first mission?... Beat up some bandits? Guard a Princess? Or Espionage?]: naruto
