Naruto: Journey of the strongest teacher

25 years has it been since I was reborn in this world. My name from before doesn't matter anymore since I forgot about it.

The name I remember was Ishizu Sasaki.

When I was young, I always wanted to be reborn in the Naruto world. It was a dream of a small child, but instead of canon; I was reborn in Kakashi's time.

A time where war was common and child soldiers were trained to kill. I don't want to tell you about that.

To summarize it, I was a prodigy like Kakashi because I had a cheat as my mind was much older and from the beginning; I learned a lot.

I also got on the team of Minato, and he trained me as the 4th member. Many things happened and I won't tell you more about my past for now but you just have to know that I did not derive the story and I didn't change canon before it started.

Still, I made my mind up to help Naruto go through his early life easier as it was in the anime and manga.

I dropped the missions I had and started to care for Naruto. I fed baby Naruto when he was hungry and read him stories when he was lonely.

I never showed myself to other people, so they started to believe Naruto was mentally retarded.

Naruto and I became friends as I was the first he started to fully trust even before the 3rd Hokage.

Now, here I am seeing a 4-year-old baby Naruto. I told the 3rd Hokage a lie that Minato wanted me to train Naruto so I could mold him as I wanted.

Naruto at this age was like a sponge, ready to be filled with knowledge, but instead, he got treated as a monster.

Having the strongest bijuu sealed in a kid was the best that this village could have gotten and instead, they threw it away.

Now, Kakashi was a mess and didn't visit Naruto. I too felt guilty letting Rin die, but I knew I could bring her back later in life.

I walked closer to Naruto: "Hey Naruto how are you?" I asked the young Jinchūuriki.

"Ishizu-niisan I am good but those people aren't allowing me to buy things except this orange jumpsuit," said Naruto as he looked at me.

When I saw it, my eyes grew wide. I knew it was his small-sized trademark, but I had a 20-year-old Ninja lifestyle and a 'kill me' jumpsuit would not be worn.

I looked at Naruto with a smile: "Come Naruto. I will buy you something good and then I will make you a real Ninja."

"Really?" Naruto looked at me with stars in his eyes. I took him to a store and bought him a back T-shirt and blue trousers, and after that, we walked to Naruto's apartment.

At Naruto's apartment.

"Now Naruto, for you to become a ninja you have to know a lot. To be a Hokage, you need to know the past as it is important in the future.

First comes learning and with it comes jutsus. If you can't write or read, you can't understand what is written about jutsus," I explained to the boy.

Naruto complained, but finally, he agreed as he wanted to learn some cool jutsus. One thing to know about Naruto was that if he wanted something done, he would do it.

It was how he still got strong despite being dead-last in canon.

At the age of 5, he could name all 5 main villages and their respective Kage. It took him some time to drop the screaming 'I will be Hokage,' but eventually, he got over it even though he does it sometimes when someone pisses him off.

As his reward, I taught him the first chakra control exercises. He needed 1 month for the leaves, 1 week for the tree, and 1 day for the water.

Sometimes I just shook my head why Hiruzen never helped him secretly.

For a 5-year-old to have genin level chakra reserves was amazing to see.

In the next 3 years, we focused on Taijutsu and the academy 3 but instead of Bushin I told him to just let it be and learn the Kage Bushin when he was ready but I told him to hide this information.

The civilian council was already mad that the fox brat was trained and they sometimes some drunk retard thought they could teach me a lesson of how to handle the demon spawn.

I told Hiruzen that giving Naruto love and train him would not only get you a strong Shinobi but also a loyal one.

He agreed and I don't know what he did but the council didn't speak up since then.

Training Naruto resulted in unexpected things. At first, it was hard for Naruto to focus. He was a bundle of happiness and I thought he had ADHD.

First, I started reading about our village and the Shinobi, and he listened because it was rare or nonexistent that someone would read him something.

Then Naruto started reading to me and I asked him after he finished the questions he had to answer.

At 6 years, Naruto could be considered a high Genin in all but battle experience. With his massive chakra, he learned all chakra control exercises.

I knew he had 'Wind' as this prime element but I gave him some Defence Justus such as 'Earth style: Earth Skin' or 'Head hunter' Jutsu in case that civilians decided to try something on him.

"Ishizu-niisan, will I go learn in the academy because I think I know everything they will teach?" asked Naruto.

"I thought it would be nice to get a few friends, you decide it.

If you want to be Hokage, you need to have connections with other clans. The Hokage should be respected by everyone so where better to start if not in the academy.

You probably won't learn much, and I would recommend that you fail and be dead last.

It is for the best because the civil council will think you will not become a ninja and they will stop annoying me. Just tell your closest friends that you need to be dead last for a reason.

Deception is one of the important aspects of a ninja. A strong ninja would get killed by a weak one if the weak deceived the strong by appearing weak," Ishizu replied.

So the next year Naruto went to the academy and faster than I could imagine 2 years passed.
