Chapter 1: After Fourth War

It was a great evening; Naruto was looking at sun setting from his room's window in Konoha and reminiscing. Fourth great ninja world war had ended around 50 years ago. That was the start of true peace in ninja world and whole of elemental nations. All nations small and big, even Samurai's had participated in the Great War, because its result was going to affect everyone. After end of the war nobody wanted to go back to previous system of fake peace, alliances and continuous threat and chances of war.

So a new system of governance was established. Daimyos of every country unified and formed a council for governing whole of elemental nations as one unit so that no previous inter-country tension was present. Now the previous country were called states e.g. Fire State, Wind State etc. Shinobi and Samurai's also formed a central council now aptly named military and police council. First Shinobi and samurai council consisted of Kages and heads of remaining ninja villages and of course head of samurais. Whole of Shinobi system was reformed now that they were unified and worked as protection and law enforcement agents for general public, Daimyo's council and finally protector of peace. Even in peace time training of ninja system was not slowed down, there was a sense of something even bigger events happening in future in every mind.

Even the excitement of future in the minds of people; most of the efforts for present were placed on welfare of general public and lifting the status of living in elemental nations. For the last 50 years spearheading all the change on the Shinobi side was Senju Naruto; but he never tried to control everything even after being offered many times the post of emperor. He was even lifted to status of god in human body, an avatar, by public due to his popularity, power and inclination to do the right thing even when the path to that aim is very hard. Military council's head was chosen by popular vote of all ninjas every 3 years. So for the first 21 years after the war he was the head of council. After that he took a leave from council's head position to spend time with his family. Now he was given a post in council for his contributions he represented fire state in the council mainly and an elder. There was also one more reason for his down to earth personality, who was none other than his wife Senju Hinata. She kept her hubby's mind from becoming too big from all the adoration and respect. She was his anchor to ground and his family was his life. In the process of welfare these fifty years, elemental nations had also gone through unprecedented technological progress.

There were no wars but that didn't mean that Naruto's life was not interesting in these years. There were many surprises that came to pass in Naruto and Hinata's life as years passed them by. First of them was that years did pass them by but they didn't affect Naruto. Time didn't affect Hinata to great extent. Nobody was sure but it was hypothesized that in case of Naruto it was the sum of four things, him absorbing some of Kurama's chakra in the womb of Kushina, second one being the Jinchuuriki of most powerful of the tailed beast from birth, awakening of rinnegan and his heritage as Senju and Uzumaki combined. While in the case of Hinata it was due to Tsunade's Creation Rebirth Jutsu and carrying Naruto's children.

Second of surprise was that persons Naruto revived with his Rinnegan during his training trip didn't age. He used this new found to give Hinata a body created by rinnegan and transferred her soul using Human Path. Current theory on agelessness of body created by rinnegan was very simple. They theorized that any and everything created by rinnegan didn't age.

This agelessness of Naruto and Hinata resulted in their gaining a bloodline which granted them a longer lifespan. The children also got a dojutsu as the bloodline. It was a new dojutsu which was mix of byakugan and fully matured sharingan.

This agelessness affected one more persons naturally, Gaara. He was ageing as normal a bit slower than normal before extraction of Shukaku but after the extraction and his revival his ageing also stopped completely. His less than normal ageing was explainable since he was a Jinchuuriki even before birth, but why ageing simply stopped it was still speculated upon.

Naruto on request from Tobirama and Gaara created rinnegan bodies for Mei and Tenten respectively. Mei was married to Tobirama while Tenten was married to Gaara.

These surprises in Naruto life were unexpected. But some surprises/events in their life also were expected and pleasant. Hinata gave birth to two children one boy and one girl three years apart. First child, a boy, was born five years after the conclusion of war. Naruto was very happy at the time of birth and gave them name based upon name given to tailed beasts by Sage of Six Paths, namely Senju Shukaku & Senju Chomei respectively. Original Shukaku and Chomei had no problem with that because he gained their respect too after he freed all bijuu from their jinchuuriki including Kurama, Shukaku and Gyuki, they even felt honored. This extraction of bijuu didn't result in deaths of jinchuuriki, since Naruto used his rinnegan and new Edo Tensei variation to bring them back to life, this even resulted in Gaara's agelessness.

He even freed Kurama by using preta path and extracting his chakra totally from him after the war. Kurama's extraction took him about three days because he couldn't extract it fast lest he die from sudden loss of chakra and also due to vast amount of chakra which made Kurama. Since he used Preta Path to extract Kurama's chakra, his chakra capacity increased rapidly again. His original chakra capacity which became around triple of Hashirama at age of thirty and was now growing slowly now tripled again. People estimated that Hashirama's chakra capacity was around five times that of a high S-rank ninja or Kage. After this event Naruto became a true chakra monster with having chakra around fifty times that of an S-ranked or Kage level ninja. He now even surpassed bijuu in chakra capacity, such that he almost equaled Kurama in chakra capacity and since his still reserves were still growing he may even surpass him.

He, Tobirama, Mito, Minato and Kushina all combined their minds and knowledge and created human bodies which can handle a bijuu's chakra and have minds of bijuu using Rinnegan, body of Shinju and seals. It took them almost ten years but they completed the task. It resulted in two favorable outcomes, first one being now no one could use Shinju body again to do any damage since it was deconstructed to give bijuu bodies, and secondly it provided bijuu freedom because nobody could now seal them into anything and they could roam freely.

Naruto thought why original Sage didn't created human bodies and he only came to one conclusion that he couldn't do that because seals were not that advanced at that time and he was on last of his life when he was dividing Shinju's chakra. Now bijuu, who after this change prefer to called by their names and if needed to define them collectively liked to be called chakra entity instead of tailed beasts. They could access all their powers in the bodies just like a jinchuuriki could i.e. version 2 chakra cloak and full tailed beast transformations. Some of them who were treated fairly still care for their villages, while rests of them were fully utilizing this new developments result by wandering around and seeing the sights.

In the last few years, after everything settled down and they reached a satisfactory level of governance, Naruto had been thinking about world outside of elemental nations. He found out about outside world from Mifune. Sometime around twenty years after the war Mifune and Naruto has become great friends after he trained Naruto in swordsmanship. He mainly taught him sword techniques of Samurai including a curious technique which applied "Haki", which is basically application of willpower to strengthen swords and body and effect environment. It came into the discussion after Mifune was able to hit Naruto even when his Kamui was activated.

After this event Mifune explained to him about haki. As he explained to him, "Haki is pure application of willpower that is having no doubt in your actions. Since its application of will power it can hurt him even being intangible because it doesn't only affect physical aspect but also affects his willpower and soul to an extent."

It was passed down only to leadership of samurai. But considering the help and contribution of Naruto in establishing peace in the Nations the leadership of Samurai agreed to train Naruto in haki. Mifune was charged with Naruto's training in haki. After training in haki Naruto found out that haki can be counteracted with sage mode and its many properties match with sage mode like high durability, minute or high preflex and increase in attacking power, and all these qualities increases as the proficiency in haki or sage mode increases. He had mastered sage mode completely, but he decided to acquire the skill of haki too. During training he also learned about the countries, islands and worlds outside of elemental nations. While elemental nations in an on itself was a big country/land but it didn't compare to the vastness of outside world.

In the time when he was being trained by Mifune, Naruto got to know more about culture, philosophies and history of Samurai. Apparently their origin was not in the elemental nations but outside them. Few people outside of iron country always wondered how samurais came to be, since Sage of six path only taught ninshu i.e. ninjutsu. They came from a country called Wano which was in second part of Grandline. Few people from the country started on an expedition to find new nations, many years before, and they came about this nation. Leader of nation was fascinated by ninjutsu and decided to stay here longer. When there was time to leave for next adventure, many of the expedition decided to stay and formed the start of what is called iron country today. Surrounding events and culture affected them and there came about some deviation from original culture, and they also incorporated use of chakra in forging and fighting.

Naruto was proud of his achievements and of people of elemental nations. But now he was in a dilemma. His ancestor's dream was to bring peace to the world, now that he knew about outside world he can't just ignore their existence and condition. But to intervene in the outside situation meant that he had to leave elemental nations and more importantly his family.

He was lost in these thoughts when Hinata entered the room after bath. She saw Naruto lost in thought and asked, "What are you thinking about Naruto?"

Naruto replied with a sigh, "Nothing."

Hinata rolled her eyes and said, "We have been with each other nearly 65 years and you still think you can hide things from me."

Naruto looked to her and said resigned, "I had not yet decided on what to do so didn't want to burden you with my thoughts if it resulted to nothing."

Hinata came closer to Naruto and asked, "So what were you thinking about?"

Naruto said, "I was thinking about the information I got from Mifune about outside world all those years ago. You know there is a vast world outside of Elemental Nations which are untouched and unexplored by people of elemental nations. We have been so engrossed in internal warfare and politics there was no time for anyone to go outside for anything for hundreds of years and if someone before that did go to outer sea there is no record of that. But now that Elemental Nations are stable and enjoying a peaceful time I was thinking about going out to sea and explore."

"Why are you thinking about this today?" asked Hinata after thinking over Naruto's words.

Naruto replied, "Tomorrow is a session of council. Many of our friends will come there so I wanted to discuss it with them and take their advice."

"Why, are you bored with me and our children?" asked Hinata in a teasing manner.

Naruto hurriedly said, "No. I didn't mean to give the impression of that. It's just that Sage of six Paths' aim was to bring peace to whole world not to only elemental nations. And I think he knew about the outside world too or at least as much that could be possible in that day and age."

Hinata said, "I was just teasing you Naruto-chan."

Naruto continued, "Shukaku and Chomei have grown, they don't need me to take care of them anymore but I can't decide to leave our grandchildren. But I think they will be in good hands with their parents and if necessary I can come here using Hiraishin or kamui from anywhere."

Hinata thought everything over and said "So tomorrow tell everyone, discuss and then decide about it. Now come to bed." opening her bathrobe in the last word.

Naruto started opening his clothes hurriedly and said,"ok". After that they lost themselves in each others' embrace.

-Next day-

At council meeting, Naruto presented the notion of exploration outside of elemental nations. Many people were in favor of this idea, some because they thought that we need to explore and know more about our world for the sake of knowledge and meet new cultures and some because they thought it will be good to know more about outside world in case there was ever a threat from outside.

So an idea of a team for exploration was proposed by Shikamaru, the resident super tactician. He said, "It is troublesome but since outside of our nations; the territory is unexplored that is we have no knowledge about that, and as you will know from Samurai's a dangerous place, so I propose people because of whom this peace we have been enjoying has been established, mainly eight dragons."

At this Mei, Tenten, Tsunade and Jiraiya equally protested and said they too wanted to come with them because they were family. After some heated discussion and threat of castration and more, it was decided they too will be allowed to go. So this team of twelve was proposed as the advance team who will scout and if necessary more troops will be sent to strengthen the scout team and to make relations with different countries and as ambassadors or as backup. It was easy for exchange of information after development of communication seal matrix by Mito, Kushina & Naruto based upon Hiraishin.

For travel on the sea a ship was commissioned by the council. Hashirama supplied strongest wood available which was reinforced with his chakra and Naruto provided Rinnegan made reinforced metals for strengthening and riveting purposes. Inari's company, which was one of the most famous company for wood crafting and making buildings were given the job to complete the ship. He estimated that it will take around six months to one year to make a beautiful ship.

After council meeting ended Shukaku and Chomei met with Naruto. Shukaku asked, "Why are you leaving us?"

Naruto sighed and said, "I promised myself that I will bring peace to the world and now you know world is much larger than only elemental nations. So I need to go out there and do as much I can to that aim. Don't worry I am not leaving you permanently I will only be one Hiraishin away. If you ever need me, you know what to do."

The successor of Mifune a man named Urakaku gave him a copy of original map used by first samurai's to come here and explained they live in east blue part of the seas and close to calm belt hence there is no travel in direction of Kaze and Tsuchi no Kuni. Now was the time to prepare for leaving.

-After 10 Months-

As the reputation of Inari's company suggested, Inari completed the ship two month before the time limit. By the time everyone understood the reasons for the exploration and was happy with them. Now everyone was able to correlate the feeling they have been experiencing with these new developments. Initially, after hearing the news, his grandchildren were sad but after he made them understand that he and everyone on the ship was only one Hiraishin away and they will come to see them periodically, they got out of the funk. Everyone was excited, there was peace, but it was a bit boring and this was the start of a new exciting chapter for elemental nations.

It was decided that Naruto will be captain of the ship; Tobirama would be in charge of security and tactics in combat situations. Hashirama was to be vice captain. Tsunade and Hinata will be medical specialists, healers on board. Tenten was weapons expert. Navigator was Mei because she initially lived on Mizu no Kuni and was more experienced and knowledgeable in navigation at sea. Mito was given the position of maintenance expert with Hashirama helping. Kushina was mainly a swordswoman knowing Uzumaki style and could use Haki, not to expert level yet, which was taught to her by Naruto after announcement of exploration. Gaara was deputy navigator and helmsman of the ship, by his request. Hinata and Naruto were also chefs because they have been cooking food for themselves from early childhoods and they had become expert in food making.

Everyone who was on board increased or refreshed their knowledge and proficiency in the time between announcement and start of exploration as much they could. They were going in uncharted territories from the perspective of elemental nations, so some new weapons were needed and developed, because in the travel they may come upon some obstacles which may be tedious or impossible to remove or overcome by ninjutsu and expertise of dragons alone. They knew that every obstacle will fall with the combined power of ship residents like Naruto and Hashirama but even then, for the sake of redundancy and for the ships on which ninja of their caliber were not available a new canon like weapon was created.

It was fruit of countless hours of seal experts like Mito and nature chakra experts like Hashirama and Naruto. Jiraiya couldn't help them because he mastered sage mode completely just few years back and didn't have as much knowledge as Hashirama and Naruto. The device uses the converted chakra nature from operating person or persons in small amounts using that as a trigger it used previously absorbed nature chakra from chakra storage seal, and convert it into the chakra nature of trigger, if two different nature of chakra were applied, then when converting, mixes it and expelled it with great range. For now mixing scenario was only possible with two chakra natures and storage seal took around two hour to replenish the chakra used after ten continuous firing of weapon. With the right mixtures of chakra type effect were devastating, like using earth and lightning chakra or fire and wind chakra. If there is 45 seconds gap in each firing it could fire 40 rounds consecutively.

A light and thin flexible armor for every person going on board was created by Naruto using Rinnegan, which had more strength and flexibility than old Dragon armor and could be worn under clothes.

Everyone came to say farewell on the day of departure. Naruto's family which was also the family to most of dragons, Choujuro, council members and thousands of people came to say farewell and good luck to them. It was start of a new chapter in history of elemental nations.

As Naruto laid eyes on the ship he was awed. He decided then and there it will be the second thing precious to him after family and friends. Ship was constructed to look very beautiful. It had seals carved into whole of hull to use chakra (again using also nature chakra storage seals) to facilitate sea travel. But seals were designed such that it didn't make it look gaudy or bad but it increased its beauty, like beautiful tattoos on a lady.

It was not a very large ship since people going to travel on it were few. It was a corvette like ship, but with a few modifications. It had 8 rooms, 6 for couples and two guest rooms, one kitchen, 3 bathrooms, one relaxation room, one entertainment room and one practice room. Practice room was heavily reinforced by seals. All of the rooms were under the deck except kitchen and relaxation room.

Deck of the ship was covered in natural soft grass and soil, there was a tree there too with a swing on a branch of it. The ship had three masts, big central one and two smaller one. Biggest mast had a flag of elemental nations flying on top of it. Flag had two concentric circles, outer one divided into six parts each one containing symbol of major countries, and inner one contained symbol of harmony.

Control wheel was on the front side of the deck was under a roof. Instead of a crow's nest there was a circular room with windows to observe the sea and scenery. On the front of the bow was a beautifully crafted statue, from wood, of Shinju in his ten tail form. The tails smoothly flowed into the railings and support hull. Shinju was kept was kept on the bow instead of traditional figures, because all chakra originated from him. And ship was named Kaguya Kamikaze in honor of first person to dream of peace and use chakra.

There were two options for embarking through calm belt and then grand line or travelling through east blue. It was decided because Grandline was more dangerous it will be better for ship residents to have more knowledge in relatively safer waters before going into Grandline.

All 12 people boarded the Kaguya and then anchor was drawn and the ship embarked on a historical journey with tears in eyes and smile on face of everyone, departing or staying. Because everyone knew it was not farewell, any one of them could come here using Hiraishin whenever their need will arise.
