Because ironically it happened to me.
And right after falling unconscious, I woke up in Naruto in a child's body. How did I know? Simple, I heard people talking about Amegakure, it's not difficult to associate one thing with another, it's like 1+1 = 2, it's not difficult. After the initial analysis, I despaired when I saw that I was reborn in a place that only had war, fighting and corruption, on the part of Hanzo da Salamandra. And then I remembered Nagato, and his Rinnegan... It was a good chance.
"So my name is Ryu? It means Dragon from what I remember."
Third Person P.O.V.Ryu analyzed the memories he had of the body he possessed, such as the basics of being Amegakure, which is a small hidden village that was a battlefield, he was a thief, a very good one in fact. However, this was not what Ryu mainly wanted to be, so taking advantage of these stealing skills, Ryu stole scrolls and books on Chakra, Ninjutsu, Taijutsu and Genjutsu.
Analyzing the scrolls, Ryu began to study Chakra first.
'The way to control Chakra would be through meditation? Although the seals help, I initially need to get used to it.' Ryu thought as he read a scroll about Chakra.
Produced within internal organs, such as the heart or brain, chakra spreads throughout the body through a circulatory system, the "chakra network", which is similar to the cardiovascular system. Scattered throughout the chakra network are pressure points called "tenketsu", through which chakra can be "emitted" out of the body, allowing the performance of a wide variety of techniques. For a jutsu to be performed correctly, after the ninja produces enough chakra, it is necessary that he has adequate chakra control to dedicate part of that chakra and manipulate it with the help of hand seals. If a ninja releases more or less chakra than necessary to activate a jutsu, it will become unstable and its efficiency will be impaired."That's interesting... I think I might have a general idea." Ryu closed the scroll and placed it in the corner of the room. He closed his eyes and began to feel the Chakra internally, starting from his belly. 'Have an image of the Chakra network, feel and spread this Chakra throughout the body.'
Feeling an energy, like a flame, in his belly, Ryu began to enlarge this flame but the flame showed resistance, making him apply more force and thus the flame began to expand.
'It is difficult...'
Naturally, the emerging Chakra would become very resistant, this is due to it not being mature enough, and also due to the lack of experience of the manipulator herself. However, the manipulator can also apply force to the chakra to manipulate it, but it is still difficult anyway.After time, the flame started to become easy to control, its resistance became weak little by little. Until Ryu could control the Chakra and bring it out without any resistance.
'That was quick, it only lasted 3 hours.'
The weather was even good, although Ryu had to admit that sitting still had never been his strong suit.
"Now, what do I learn now?" Picking up the parchment again, Ryu opened it and began to study more.
It was a lot, it would take a lot of time.
...
In the streets wet with rain, Ryu entered a ninja store and took advantage of the fact that the salesman was sleeping, he ran and grabbed some papers and parchments, then quickly left and ran as far as he could. Returning to the hidden room that was at the top of a building, it was a well hidden place that no one would go to that place.He threw the scrolls into a spot on the other side, opposite a stack of books on Chakra and Basic Ninjutsu, Genjutsu and Taijutsu Techniques.
Ryu first took some Sensitive Papers, and made the Chakra flow through the paper.
The paper was then divided into 5 pieces, one burned to ashes, one crumpled, another turned to dirt and crumbled, the last one became damp.
'Is this the Five Elements?' Ryu thought in surprise before turning to the scrolls he picked up. 'It's a good thing I got it from all the Five, otherwise I wouldn't have to go back there.'
He started with the Earth Style, or Doton.Specifically, he wanted the barriers and trap possibilities of the Doton, in fact, each Element had its advantages, the Doton was mainly terrestrial barriers and traps, although it had other abilities, the barriers and traps were what most had in the Doton.
"First, the Mud wall."
First was the hand seals.
Tiger → Rabbit → Boar → Dog.
Then he molded the Chakra and spat mud from his mouth and formed a wall 35 centimeters thick and 10 meters high, almost reaching the ceiling.
"Perfect." Ryu smiled as he felt like his chakra hadn't even decreased because of that. It seems his chakra was pretty high too.
And for days, he learned each Doton Jutsu that was in that scroll, until on the 10th day, he finished the Doton scroll.
Then he left for Raiton.
This was an element that would work well in Amegakure and the Land of Rain.The days passed while Ryu trained tirelessly, he walked around the village and its surroundings, until he found a young girl with short blue hair sitting in a cave, hiding from the rain.
He recognized her and approached.
"Hey..."
The girl looked at Ryu who extended his hand.
"Come with me, I'll show you a better world than the one you're seeing now."
The girl looked at Ryu for a moment, before asking. "What world is this?"
"A world without hunger, without wars, without any kind of pain, a world where no children like us have suffered..." Ryu spoke as his scarlet eyes met Konan's amber ones. "And all I need is you."
"Why me?"
Ryu smiled.
"Because with you by my side, I will have the determination to do what needs to be done, you... Are special to me." Ryu smiled, and at the same time the rain stopped, the sun shone over Amegakure for the first time, the girl's eyes were taken by the light and she took the young man's hand.
From afar, a young man with spiky orange hair watched and heard everything.
