Disclaimer: I do not own Bleach And Naruto.
Soul society was the afterlife or known as heaven which was just big lie. It was divided in 2 parts first was rukongai. It was divided into 80 districts the farther you go from center the number of district increases. The farther part of rukongai is lawless region and nearer to the center the peaceful the region. It was also the poorest part.
Second part is the home for military group of soul society &was called seireitei and they were called soul reaper or Shinigami. This place also was recently build and it was still in the process of modification. This place was lead by 13 people and they were referred by captains. This thirteen people lead this military system and it had gained reputation and recently three captains from this militia were taken to royal palace dimension. This place was lead by the man of age early 50. He had very thick mustache and was bald. He had scar of battle in that bald place. His name was Yamamoto Genryuusai Shigekuni. By his side was his trusted partner his zanpakuto ryujin jakka. He was in his chamber deep in thought about his most powerful captain Unohana Yachiru. ' It's been 15 years since she left in the farthest region for adventure and she had not returned yet. I hope she return soon after those three left its difficult for us to maintain these warriors.'
Few miles away from there were two figures were walking toward seireitei. First was women(same get up as canon even hair style) and second was young boy who looked like the age of 18. This was Naruto he ha two bangs of hair that framed his face and was wearing a red scarf(same hair style as Minato Namikaze without head band and red scarf that Hinata knitted in The Last Movie) and normal shinifami garp.
"~Kaa-chan when we will reach that place?" whined Naruto.
"Very soon Naruto-kun", replied Unohana Kindly.
During this time of Unohana outward changed drastically as she changed to kind women who tends sick people like a doctor. She still held her blood thirsty side and kept her battle instinct and talent sharp by daily sparring with Naruto. Naruto had not changed much in appearance but held himself like warrior he was. His zanpakuto rested on the left side.
"Then let's play tag mom, I first" after tagging his mom he shunpoed toward seireitei. Smiling at the antics of her she chased after him. But she knew that she couldnot catch him. After few second both reached there destination and stopped there game. As Naruto was not familiar with this place he quietly followed his mother and was eagerly watching here and there in awe as this was most developed region. After walking for some time they reached the only two storied building and after going to top floor Unohana knocked in the door. Behind the door by sensing the spiritual energy of Unohana smiled and told
"Enter"
When two people entered his office Yamamoto was somewhat surprised by the change of the captian would be understatement. Gone was the bloodthirsty beast and came the beautiful kind lady. Gone was the look of master swordsman and was the lady whose appearance was of like of house women.
"Yachiru-chan, what's with the change in appearance?" asked stunned Yamamoto.
Hearing familiarity in the voice of the man Naruto became pissed and he placed his hand on the handle of his katana and warned. "What's with 'Yachiru- chan' baldy teme?" hearing that the eyebrows of said baldy twitched. While inching his hand toward his zanpakuto was about to retort but Unohana had already started talking.
"Naruto-kun he is senior so it doesn't matter what he calls me." She turns toward Yamamoto and told, "Sou-taicho I just returned from a long journey and I am tired so let's cut pleasantries and talk about main point. And I am no more Yachiru I changed my name to Unohana Retsu."
"Ok then. Unohana Ya- sorry Retsu the sodai Kenpachi and taicho of squad 11 welcome back to seireitei."
"Thank you. And I have a request."
"And what that is?" asked Yamamoto. "I want to lead squad 4 and my son as lieutenant of said squad." Was the request of Unohana. He knew that she was the best choice as the former captain was in royal dimension. So he agreed mentally to give the position to her and her s… "WHAT HE IS YOUR SON?" yelled surprised bald man turning toward Naruto.
"Yes sou-taicho. Naruto-kun introduce yourself." Said Unohana. "Yes mom. Hello my name is Naruto Uzumaki Namikaze Retsu and you can call me Naruto Retsu." Said bowing Naruto.
"Nice to meet you Naruto. Unohana what are the skill of your son." Asked Yamamoto.
"Well he is quite skilled and his skill sets are …"
After 100 year.
Naruto pov
After meeting with sou-taicho my mother started leading fourth squad started taking members with best medical required spiritual control. During this time many things happened, Yawch the son of soul king rebelled and the consequence was war. This war caused many casualties most of them were taicho. During this war I went to peak of my shikai and was in the process of receiving bankai. During this war we fought against the group called Quincy. But after war they all vanished in shadows and I knew that they will return stronger than before so I have to be stronger than them so I trained to gain bankai and I am going to master it. After the war I had talk with my mother and sou-taicho about the war.
Flashback
"Kaa-chan, this war caused us many casualties and that Yawch will return and we have to be ready. They have gone within the shadows and reside within that." Said Naruto
"Naruto-kun how do you know that they reside with in shadow." Asked perplexed Unohana.
"I have seen them entering in that. I am not sure but I can guess that they will spy on us using shadows so we should find a way to gain strength from being out of their radar and inform every future captain." Said Naruto.
"Are you sure about informing that delicate information to wet behind ear captain." Spoke Yamamoto for first time in the meeting.
"No, that will put soul society in danger if those captain decided to disclose that information or use it against us. So we will let a captain gain experience for 200 years and pass the test that we three will derive for them without their knowledge. If one of us fail them then we won't tell them anything. And no one other than us and passed captain should know about this protocol. Is that agreeable?" told Naruto. All three of them on that topic and made plan for future of seireitei and about their training plans.
Flash back ends.
After that time we found a place very far from seireitei. That place was a cave and at the other end of cave there was a beautiful valley. This valley had very thick spiritual presence in air and perfect for our training. And we agreed that every year one of us will go there to hone our skill.
For the past century old reapers were gathering promising people from rukongai and were forwarded towards academy for six years course to form their base which would improve in future through experience. Many student graduated and many died but still the number of soul reaper was increasing and it was easier to maintain the crime in rukongai and the hollow rate was also decreasing which is very good for afterlife of people.
Time skip 200 years
For 200 years kaa-chan, Yamamoto-san and I are keeping our skill sharp. We occasionally spar to keep our skill top notch. During this time I have mastered my bankai and all the use of it and shikai during battle. I have also mastered my shunpo and looking forward to increase the number of after image. My potency of spiritual energy was also increasing and control over it was high grade. When I was alive I used to act as a goofball even after becoming hokage to keep my skill and battle skill hidden and I have taken same demeanor to keep my skill hidden and it was fun to mess with other. I still prank all the time kukukuku …
I have many friends among the reapers in the soul society and among them two are the best. One was Kyoraku Shunsui fourth seat of first division under Yamamoto and Juushiro Ukitake fifth seat of same division. They are my best friend and we have lots of fun together. Those two are personel students of Yamamoto and strong fighters.
Kyoraku specialized in zanjutsu and was in forward to become master swordsman and Ukitake specialized in kidou. He can even simple kido for deadly force but they had one thing in common. They both are first twin blade user I have three so I am not in that category.
Katen Kyokotsu is the zanpakuto of Shusui. Its power of shikai was to make child game in game of death.
Sogyo no Kotowari is the zanpakuto of Ukitake and its power was to absorb the attack of opponent to return it to the foe. Those two may seem like lazy laid back and sick but when the time called for they both are deadly foe.
Recently Yamamoto had picked his old friend Chojiro Sasakibe as his fuku-taicho. He had recently achieved bankai and had the zanpakuto Gonryomaru which was of lighting element. He was like me who had promised to serve Yamamoto whereas I serve my kaa-chan.
Time skip 800 years
"AHHHHH…." The voice of pain can be heard from the jungle in 64th district of rukongai as the said soul of the owner of that vanish in white light. Watching this event were three man, all three of them had dark sneer as the event happen in front them and apparent leader which was in between sighed and said,
"Yet again another failure.."
