Chapter 1: When the prince leaved.

In the royal palace of Wei, a child with blond hair looked through the balcony of his room, he could see the people of Luoyang preparing the celebrations for their princes birthday, it has been a year since his life had changed.

Flashback

A 5 years old blond boy was hiding in the Hokage's office, an angry mob formed by ninjas and civilians had chased him up here taking advantage of the fact that said old man was on diplomatic mission out of the village, said mob kept pouncing on the door.

"What have I done to them? Why do they attack me?" The child thought while the mob insisted on his attack, suddenly an extremely strong impact on the door caused the fall of a photo of the fourth hokage, behind which was a compartment that contained a scroll with his name on it, Naruto had learned to read at an early age using the hokage, so he grabbed the scroll and began to read it.

The scroll revealed to him his heritage and the presence of the kyubi, and on a seal on the scroll were his inheritance, the jutsus that his parents thought he would need other than their personal jutsus like the rasengan and his birth certificate signed by the fourth and the third.

When he read the scroll the boy decided to ask the Kyubi's help from the Kyubi, in exchange to find a method to pull him out of the seal without dying in the process, he would help him flee and take a little revenge against the village, after the fox accepted the deal, Naruto ceded the control of his body to the fox, he took out the birth certificate, copied it and fleed the office undetected leaving a copy of the certificate on the table of the Hokage, another on the council hall and took the original with him.

The boy fled to the west with the only company of the fox for a month, training in ninja techniques thanks to him this and the scrolls of his parents, finally on the borders of the Kingdom of Wei, Naruto found three bandits who had kidnapped a girl his age and were threatening to rape her if she didn't stop kicking.

To the surprise of the bandits, the largest of the three suddenly fainted and Naruto appeared above his body, the other two tried to attack him, but taking advantage of his small size, his speed and basic jutsus the young traveler defeated them and tied them together with his obese partner.

While he untied the girl, a group that could only be described as a small army stood before them, the woman who was at the head of the group dismounted her horse and jumped immediately to the girl holding her in an embrace.

The girl turned out to be Sousou, Princess Wei and daughter Sousong which at that time was very busy trying to crush her daughter, when she finally decided to release the child, her group had set up a camp at the site and the bandits were in a cell being interrogated.

She dedicated a questioning look at the blonde child, "I thank you from the bottom of my heart that you rescued my little Karin, but may I ask what is a small child like you doing here without his parents?"

Naruto told everything to the women, from him being a jinchuriki to his parentage, the woman felt amazed with the child, despite the treatment he had received from Konoha the boy didn't want revenge (beyond making them know their mistakes through the certificate) determined to cheer the guy up, Sousong shouted the soldier that was closer to her "send a messenger to the path of the five grains, tell them to send an expert on extracting energy"

She then turned in the direction of Naruto, who at this time was stroking the head of Karin who was sleeping on his lap.

"Naruto-kun, get ready to improve your life," she said smiling.

A week later a doctor from the way of the five grains extracted the kyubi from Naruto, which deleted the whisker-like birthmarks of his face, before leaving the kyubi leaved a present to him, a small fox to help the kid on his fights, but the best was yet to come.

Arriving at Luoyang, Sousong announced Naruto as her son and brother of Sousou and gave him the name Souren.

/ Flashback

"Naru nii-chan do you want to come for a walk with Shunran, Shuunra and me come Shunran?" asked the girl who was his sister in all but blood, he gave her a sad smile and hugged her, "I'm sorry Karin-chan, I have to study with mother today? How about going out to eat together later?"

The little girl nodded with a smile, before leaving her brother's bedroom.

Since the boy was from the elemental countries, his new mother had decided to make sure he learned everything needed to be the heir of the kingdom with her sister, fortunately thanks to his Kage-bushin, that he learned in his parents scrolls, he would only need a few more lessons before finishing his learning.

Karin and Naruto had lunch together and were about to leave the restaurant where they had lunch when some girls a few years younger than they collided with them, the restaurant owners came out to apologize for his daughters, but the young princes made them a reassuring gesture and smiled at the girls, calming the two restaurant families and thus starting a friendship with the small Ten'i and Kyocho, a friendship that would be very productive for them on the future.

Meanwhile Konoha received an unexpected visitor, a man with long crimson hair was sitting in the Hokage's office and while he waited he smiled to himself after seeing some changes in the village.

"Hokage-sama, I note that many of the business in the town have been closed, what could be the reason?" asked the redhead.

"For some reason the western countries have cut all contact with us, Kurama-san"

Replied the old man, causing his guest's smile to spread.

"Ara? last time we saw each other you called me an abomination, I guess the years change the humans" Kurama said taking out his nine tails and using them to immobilize and silence the Hokage and the ANBU operatives in the room.

"Well Hiruzen, calm down, I didn't came here to destroy anything, but to tell you that the kit's still alive and happy where he is, and to explain what happened 'that' day" and holding them prisoners, the fox told them what happened that October 10.

-Timeskip, five years-

Naruto and his sister were sitting in the throne room before their mother waiting for her to talk.

"Naruto, Karin, as you know, only one of the two of you can be the heir to the throne, usually this should fall on Karin, but I want to know your opinion on the matter. "The woman said, and almost instantly Naruto raised his eyes and spoke.

"Mother, I think Karin is the most appropriate for the position, I'm more a warrior than a diplomat, she is more capable and respected" Said girl was completely blushed and tried to deny it, but was defeated by her mother.

"It's decided then, Naruto will be the one to inherit my place."Seeing that her words caused confusion in her children, the woman smiled and explained her motives.

"While it's true that Karin is respected by the villagers, so are you, also instead of trying to monopolize the power, you chose to give it to your sister for what you believed was more right for the people, plus you're the one that achieved peace with the Tô faction by befriending Toutaku."

"But mother, if Karin doesn't inherit the throne she will be obliged to marry someone of high birth by our laws," said the boy trying to convince his mother to change her opinion.

While it was true, that the West was almost completely dominated by women, the laws forced the daughters of prominent families to marry the heirs of other families to win more political and economical power, of course Sousong had prepared a solution in this regard, she just hoped that said solution occurred by itself rather than having to force it, because it would be rather difficult with the interests of his daughter on regards to the relationships.

"Until you two reach the age of 18 years old it won't be official, so you have another 7 years to find a satisfactory solution, meanwhile I will continue deliberating" It goes without saying that Naruto was looking for a way to resign, while Karin thought of a way to explain to Naruto something that eated her form within, the opportunity was presented to her that night.

Karin was relaxing in the hot springs of the palace, thinking about what happened today, when the usual sound of Naruto training reached her, however a different sound alarmed her, that was the sound of an explosion, and then a cry, altered Karin rose from the wather when a geyser emerged before her and the sound of the cry trailed off.

'Ok, mental note don't to call kii-chan a glutton , who would have thought that Ruru and had so much strength' Naruto thought as he pulled his head from the water, running on all fours, as he looked ahead, he remained completely blocked, before him was his sister, her beautiful blue eyes fixed on him, her cheeks slightly flushed and her lips forming a strange smile.

"Naruto, I want to tell you something..." she said as she grabbed something that was on the floor, right where he knew she left her scythe while bathing...
