I do not own naruto anime, manga or other released formats.
Well Naruto managed to heal from the stressed caused by his chakra pathways expanding. He was just fine by the time the medics release him, except for several problems, first he was going to need new clothes, he apparently grew a few inches and his clothes did not quite fit right, but to his surprise Mikoto was actually pretty good with a sewing needle. She fixed his clothes and saved him a good amount of money. The second problem came as she started to fix his shirts, and asked him to give him the ones he was wearing, she managed to repair the others just those needed fixing. But when he removed his clothes she saw his chest, his muscles, his abs, his powerful strong legs, and something that made her blush. Because of the growth he had gone thru the boxers he was wearing now looked like brief, and his package became quite noticeable. Mikoto was torn between telling him to cover up with a blanket, and simply jumping him and tossing caution in the wind. A few kunoichi came to the tent to see if Mikoto needed some help, and when they saw Naruto like that they always left with either saying something about Mikoto being lucky or calling him a hunk.
Kurama was quiet, and quite busy her fur really was a mess of knots, and the smell was giving her a hard time. She ended up taking a bath several times before the smell finally disappeared. But the knots did that guy ever hear of a comb. Her chakra had doubled and it was pretty hard to keep it under control, and do delicate things like straighten her fur, specially in those hard to reach places. She was tempted in asking Naruto to help her with the fur on her back, but she remembered that there was this annoying barrier that kept that from happening. She ended up using some clones to take care of it.
The last problem had been from the rest of the camp, they kept making comments that he and Mikoto should do the decent thing and get married already. They said that they behave like a couple of newlyweds, that they should get the ceremony done and over with. Sakumo put an end to that teasing by saying that he was not about to send two of his most valuable troops so that they get married, the time of getting there, the ceremony and then the honeymoon. He told them this camp would be either captured or dead by the time they got back.
Mikoto was always smiles when she was near him, and the looks she would give to other kunoichi who tried to flirt with the new and improved Naruto as they had a habit of calling him was of poor murder. Her attitude towards them was clear as day, she was basically saying he is mine, and if you try and take him I will make you see hell. Koji and his partner often joked with each other about how did Mikoto go from kindly family member to jealous lover in a matter of days. A jounin that heard that decided to put in his opinion and told him, "Sometimes in the heat of battle relationships can either grow stronger or break up. We could die any moment so the time with a loved one becomes that more precious." Koji simply did not understand why he would know, the jounin simply told him that the head kunoichi healer in camp was in fact his wife. They became involved, and eventually married before the end of the 2nd world war.
Koji felt that maybe he should try and find himself a mate, that was when the formerly mentioned healer went to look for her husband, and found him chatting with the Inuzuka and his nindog. "You need to simply make yourself available. Trust me, when a woman wants a mate she will be the one finding you!" All the men and the nindog looked at her, she was right but it was sure a hard thing to hear.
Sakumo was worried about Naruto as well, the extra chakra would have messed his control, and controlling your chakra was vital in combat situations like they were now. Combat against the camp had happened less and less, it seems Suna was finally getting the message. Mess with this camp and you will have to expand your cemetery. The newly appointed Kazekage was even doing secret negotiations with the Hokage to declare peace between them and even enter a possible alliance to deal with Iwa. Lady Chiyo was a big promoter of this she did not want to ever be in combat against that armored fiend from Konoha for as long as she lived.
After 2 years of combat, and the council in Suna seeing that their ninja ranks where being decimated by the war, they finally saw the wisdom in what Lady Chiyo of what her and the knew Kazekage had been trying to get them to see for those 2 years. Mikoto, Koji, and Naruto made full jounin but also did several others. They finally would have a months leave to see their family, and Naruto told Captain Hakate that he was doing special training to get ready for the Iwa offensive. Minato and Naruto became the best of friends and Kushina joked that when were they going to see the two finally marry and give them some little godchildren to spoil. Kushina took the loss of her biju as many would, a blessing. She did not have to deal with the fur ball's constant blood lust. Her relationship, health, and outlook in life improved 100%.
The hokage was happy to see that most of the troops had made it back, but still held memorial services to those that had died. He wrote letters to the families that lost members and he would always say that they were by far the hardest letters he ever had to write. How do you tell a wife in a letter that she would never see her husband or that her child will have to grow without a father. The worst had been where he had to sent the children of couples that both died in the war. The life of a war orphan was never easy, and seldom was it a happy one. Kagami welcomed both Naruto and Mikoto with open arms and a smile, but that smile ended when he met with the one eyed heavily scarred face of Fugaku glaring at them. Kagami was not feeling an once of pity for him, you try and hog all the glory in a war and you will pay for it.
Naruto talked at night with the wolf boss Fenrir, he too told him that the only way to improve enough to be able to use the extra chakra was for him to go to the wolf summon territory and train with the elders. He was told that the place had a nice village but the problem was that time was different there and in Konoha, in the month he trained there he would eventually end up the same age as Mikoto. He would have to explain why he had gone from a late teenager to a mid twenties adult. He simply did not pay much mind to that, Mikoto was not that superficial, and Kagami would trust him.
Naruto was then summoned to the wolf summon territory, and he was greeted by Fenrir's own daughter. They took a time to get to know each other and became good friends, by the time they arrived at the village. He was supposed to train his chakra control with the wolf elders, but instead he was told by the elders that he was going to do something no one has done in thousands of years. He was sent to the wolf sages, to learn the ancient and noble art of seinjutsu and become a wolf sage. The elders tried to scare him and told him that it was an extremely heavy training regiment, to which he laughed. In a puff of smoke 1,000 shadow clones were also laughing. He pointed at the clones and told the elders with this group I will finish the training, the wolf elders looked surprised but in the end that would have to believe it.
