On Earth, a young man of about 30-years old with great intellect and views about the world was on his birthday party, it was one of the few days that he took a break, being born as an orphan but having an IQ of 369, being the person with the highest IQ ever recorded, he was taken by the government and studied everything possible, the boy had a special interest towards genes and the human body, therefore, he studied it with more effort.

After exactly four years, all of the knowledge known about genes and the human body were learned by him and in more six years, he started to develop an elixir that would give the 'Perfect Body', while the young man named Ale was indeed someone that cared about humanity and it took part on this experiment, his true reason was different.

No one knew but he was a fan of the anime 'Naruto' and wanted to create this 'Perfect Body' to be able to use the energy of this certain animeverse, however, is a failed experiment, an explosion happened and he died instantly, instead of going to Heaven or Hell, he was on the boundless void, where only space and darkness were his partners.

Millions of years passed as he mumbled every day about why the experiment failed, about his existence and more things like what's the meaning of life, etc...

One day, however, the now more than one million years old ''young man'' was suddenly s.u.c.k.e.d by light as he appeared in an unknown place.

Where am I? This is the first thing that came to my mind as I stared to someone with a blurry figure in my vision that is holding me, giving the situation and my strangely small body that I can't even move with freedom, I'm probably an infant, I have to admit, the feeling of having a body after millions of years in the void as a soul is comfortable.

Luckily, the language that the person in front of me is the same as my world, I'm not sure if I reincarnated in the same world or a different world but what I heard cleared my doubts ''His name will be... Senju Shiro'' the voice of a woman sounded in my ears, I'm calm but also in ecstasy, the only regret, in my opinion, is that I wasn't able to see what came after the end of Naruto Shippuden, sigh...

I can confirm three things by analyzing this simple thing that I heard. One: I was born at Senju Clan, Two: I'm at the Narutoverse and Three: I'm at the Era of the Warring States, which means I probably won't be able to see the original plot.

Of course, this is given that I don't find a way to become immortal, by the way, what are these strange particles everywhere? Is this chakra? If so, why was this never shown on the anime and why am I able to see it? Sigh... I'm already sleepy, judging that I was just born and that I'm only a baby, there's nothing that I can do except sleep, bye everyone.

My perception of time is different from a normal person, I mean, after millions of years on the void, one year is nothing to me and it passes quickly if there isn't something interesting, anyway, I'm not sure if I'm abnormal but at four months old, I was already able to walk and after one year, I was able to talk, well, this one is rather normal, after all, I wasn't mute in my previous life.

I decided not to talk about these particles to my father and the clan because I'm not sure if this is a normal thing or not, however, I learned somethings, my father is the twin brother of the current Senju Clan Leader and I don't know who's my mother but I got to know something, my uncles is the father of Hashirama, judging by his young features right now, Hashirama will be born after around fifteen to twenty years.

While I can indeed feel these strange particles and possibly absorb it, I saw that in the anime, the best age to start refining chakra is about four years old, which is three years from now, it won't be too long, for me.

By the way, my father is named Senju Asuha, I immediately thought about the name similarity with Otsutsuki Asura but just shrugged it off because I know that Asura reincarnation will be Hashirama and then Naruto, the current clan leader, my father twin brother, is named Senju Haruka, I liked the name and he's very nice to me, though I don't like when he calls me 'cute baby' even though it's true, I'm an old monster with more than one million years old, though my mentality isn't of one.

In a flash, three years passed and I was already four years old, in front of me was my father, that started to explain ''Almost everyone has chakra inside of their body, some people have more chakra and some have less, people like us from Senju clan is born with a stronger physique and we usually have extremely high amount of Chakra, being comparable if not better than our ally, the Uzumaki Clan, Chakra is essential for someone like us to get stronger''

Then, he started to show me the Senju Refining Technique, all techniques are the same in essence but the Senju and Uzumaki techniques are different due to these clans physique, I understood and through the guidance of my father, I started to absorb these particles around me, that was quickly drawn towards my body and soon, I felt a strange, warm feeling flowing through my entire body.

An unexpected thing then happened, my eyes started to heat, not in an uncomfortable manner, it was warm and refreshing, I was already surprised and started to guess, however, when my father confirmed it, I felt shocked as I heard him saying ''You... awakened Sharingan!''
