In Naruto Trying to become a Saiyan from Kumogakure

At only six months old, Ron had already begun to crawl across the wooden floors of his family home, his movements surprisingly agile for a baby of his age. What truly astonished his mother Raiya, however, was his ability to form simple words.

Which she was quite worried about as the kid never made much trouble and only cried to express his physical needs, and was even silent and rather disinterested in toys and other people, such as the maids and others who took care of them.

In Raiya's eyes, Ron's eyes would sparkle and show interest only to her and their family members or when her Husband and Son would be home and talking about ninjutsu, She herself at one point been a Medical ninja and the secretary of Raikage so she recognized when her young son showed interest, but still never babbled or played with things, that is why she was worried since as a medical ninja and mother she knew at this age kids show interest in everything around them.

Suddenly one day she heard the word "Mama," which Ron said one evening as he felt enough development and control over his body, his small hand reaching up to grasp her fingers as she prepared his meal. Her eyes widened in disbelief, but the pride in her expression was unmistakable. She bent down and scooped him up, played with his chubby cheeks, then pressed a kiss to his forehead.

"You are something special, aren't you?" she murmured, holding him close.

At this moment Ron in his mind was silenced, as he was thinking, "Although it's nice to be kissed, as a grown man I don't want to be kissed and I don't want my chubby face to be played with!"

In his past life, Ron was a quiet child who only showed interest and enthusiasm for things that truly captured his attention. As the only son in his family, he was doted on by his affectionate parents, whose overly cozy demeanor often made him feel shy.

Despite his precociousness, Ron's world often felt quiet and lonely. His father, the formidable Third Raikage, was a rare presence in his life. When he did visit, his towering frame and seriousness and sometimes the booming laughter filled their home, but those moments were fleeting. His older brother, the Fourth Raikage, was much the same an imposing figure Ron had seen only a handful of times since his birth.

They were shinobi, protectors of Kumogakure, and their duties often kept them away from home.

But that did not bother Ron; as Ron felt that his life could have not gotten better, he felt like he was high on his thinking, during the time he could stay awakened as a baby.

Ron would think about questions and problems he pondered on in his previous life and would find that things have become clearer and more concise, even a perfect reoccurrence of details could be remembered.

Ron was surprised by this. "I guess in this life I have a perfect memory and clear thinking? But can babies even think like this at age or is it my soul that travelled through time is having these thoughts?"

Ron concluded that If it was his soul that was having the thoughts, he could think more, but that was not the case. Ron concluded that if he was just the soul he may not need to sleep without the restriction of the body, similar to the beings summoned by the Impure World Reincarnation technique.

But living beings are bound, and they grow and flourish with the body and soul, like Yin and Yang.

Ron found that he could sense this magical energy in his body that, like a seed existing in his cells, it could be controlled.

This was Ron's chakra, as every cell does contain a trace amount of chakra, inherited from parents, Genins sense this initial chakra within themselves, which allows users to use it as a starting point or key to the refinement of more chakra by automatically absorbing more spiritual power and physical strength. 

Ron concluded that this is done by the initial chakra seed inherited; making chakra refinement easier, of course, the chakra refined is controlled by the combination of physical control, will, and spiritual strength of a ninja, as chakra is the combination of physical and spiritual strength.

In the ninja world, not everyone can have chakra or refine it, if kids are told to sense their physical strength and spiritual strength and combine it to make chakra, just sensing it would be an arduous task, if this was so simple then anyone would be a ninja. 

Ron guessed that during the six-path sages era, where he spread chakra, he spread a trace of chakra to the ninja sect initially, or else it would not be easy for humans to control this foreign power this easily.

Ron sensed the chakra spread throughout his whole body and determined that every cell in his body had a trace of it, maybe due to his reincarnation, he had an enormous spiritual strength, capable of understanding and clearly sensing his own body.

Ron determined that for ninjas controlling chakra is pretty easy, but just sensing and controlling spiritual strength and physical strength, seems to be possible only for those experienced medical or sensing ninjas and other strong ninjas.

Ron carefully felt the trace chakra in his body and he was surprised by it, Ron was able to sense that the chakra carried personal information and traits, most of it was made from his spiritual power, which should have been his parents, as he had never refined chakra, but during the time his body was growing in the womb probably left his mark on it as it's in his body.

The physical aspect of the chakra should carry his parents' info, but he is made out of the information of both his parents so in a sense it is his.

Of course, the chakra in his body will change as he grows up and as he changes. About the characteristics of his chakra, Ron thought more.

"Maybe only by giving birth, 2 people's chakra information and physical cells create a new life without conflict, since in the anime transplanting bloodlines seems to be not such a successful thing, even awakening the bloodline limit of your family is not that easy as shown by the wood style experiments, maybe even if you inherit the physical aspect and chakra of your parents initially something will be lacking spiritually or chakra wise, as even the inherited chakra would change to be yours slowly!"

After all bloodline limits and chakra traits of ninjas are created and affected by chakra through the long history of time after the spread of chakra. Even if blood can be inherited, the spiritual aspect is unique and might not change the required way despite being affected by the blood.

Ron concluded that in the ninja world chakra is the key and bridge between the physique and soul. Your blood can affect the soul through chakra and vice versa, most importantly, chakra more malleable is the key to permanently changing and affecting the blood and soul. Through chakra, you can evolve and change or even refine your genes and soul, which is faster than biological, evolution.

This gave Ron ideas and hopes about the future and what he wanted to do.

However, as Ron delved deeper into sensing his chakra, he discovered a faint and foreign spiritual imprint embedded within it. The imprint was weak, barely discernible, but its presence unnerved him.

Ron wondered if no one recognized it or if it was hard to discover.

He doubted that, in the ninja world there are many geniuses and crazy ninjutsu developers who play with the soul such as the 2nd Hokage Senju Tobirama.

Ron realized this is something he is recognizing only because he is sensing the chakra seed at this young age, which is only possible not only because he has a strong spiritual power, but he has an adult mind and formed consciousness, adult ninjas who might be able to sense this in the future would find it almost impossible to recognize and discover as it has become part of them at this point.

This scared and surprised Ron, thankfully it was nothing to his spiritual power. Ron tried to remove and destroy this small spiritual imprint, which is even weaker than a normal baby's spiritual power. It was done.

But this kept Ron thinking and he finally concluded, that this was probably something that Kaguya Otutsuki or Sage of Six Paths or The Otutsuki clan left in chakra. Thankfully it was just like a speck of dust or a small hidden key hiding in your firewall, in your chakra.

"maybe that is why the Otustsuki and Rinnegan can absorb chakra so easily, and that is why sage of six-path could connect everyone's chakra so easily, or else each individual's chakra is unique how could it mix and mingle so easily without suppression?

"If Kaguya Otusuki and other Otutsukis could absorb everyone's chakra without limitation, and surpass all the spiritual aspects of all these chakras, then with their soul strength they would already be a true god, and just directly control all the people by suppressing them spiritually.

Who knows what other hidden threat there is to it; Ron thought and decided to remember what this imprint was like, and determined to remove it from his family and all Kumogakure ninjas if possible.

"Maybe I should invent some kind of device to allow other ninjas to discover it themselves, after all, chakra is something very personal!"

Determined to protect his new family and village from potential threats tied to this discovery, Ron vowed to develop a device to help ninjas identify and remove such imprints. Exhausted but resolute, he fell asleep dreaming of creating innovations far beyond the current era of shinobi. Even beyond the Boruto Era, after all, Kumogakure could be considered the most advanced in terms of technology in the current world except for a few individuals like Orochimaru and others.
