Time skip 5 years:
Right now, we can see a man in his thirties sitting infront of a pile of paper works this man has very distinguishable features of gravity defying silver hair and he wore mask to cover the lower part of his face and has scar over his left eye that reached from forehead to the cheek,he wore a dark green jonin vest behind it has written sixth hokage, this man is infamous in the elemental nations as 'copy ninja's who copied over a thousand jutsu with the sharingan given to him by his teammate obito and his name is Hatake Kakashi.
As kakashi is doing his paperwork he was about take another pile he heard a knock on the door and put it aside and welcomed the people outside the door the person who came was hyuga hinata who has grown beautiful and strong over the years with her lavender eyes to her silky black long hair with she entered the office with a sleeping child of three years with yellow hairs that look like apples top in the front and has two whisker marks on each cheeks who is son of hinata and Naruto, as soon as they entered a smile tugged at sleeve of the elderly mans face seeing his students son who is just like him at the same not made his heart warm and the next person was his another student Sakura haruno with her bublegum pink hair and a violet diamond mark on her forehead and a smile with a girl of three years who has black hairs and wore red dress with uchiha clans crest on the back is the daughter of sasuke and Sakura who both married three years ago.when he saw them he remembered It's been 5 years since both Naruto and sasuke left the village to train their new powers and enjoy their life.
"What is it Sakura, hinata why are you two here" asked the masked hokage knowing full well they are here to ask about when his students Naruto and sasuke are coming with a warm tone.
"Well we wanted to when both of them are going to come back" came Sakuras question with a warm smile who has slowed her temper after marriage and child. "It's been five years heh.. time really flies doesn't it I remember doing bell test with you three like yesterday"Kakashi said in a melancholic tone remembering old days"well, they both must be coming today or tomorrow"
"It's that me and Naruto still haven't married and I even haven't told him about Boruto, do you think he will be mad at me?afterall he wanted to have family "shyly said hinata thinking Naruto might become angry at her for not telling that she has his three years old.
"Don't worry hinata, he'll understand afterall it's because of his training you kept it from him if you've told he would be distracted to train " Sakura said
Suddenly they felt a chakra signature of the person they knew very well near konoha gates the young man is in his early twenties and his prominent feature are black hair coming to shoulders with his left eye covered and his right eye is onyx black eyes and when wind flutter and his locks slightly altered we can see his left has purple irisis with four concentric black rings and dot in the centre and has 3 tomoes in first two rings from the centre.the man wore purple shirt black pants and black cape with black shinobi sandals with a chokuto on the back with no emotions on his face he came from the black portal created by his rinnegan space time ability. As soon as he entered the gate gaurds and anbu perked up and watched his every move as he entered the village and without registration he started walking directly towards hokage tower as a new gate gaurd was about stop the new comer the other one stopped him in his tracks saying that man is Sasuke uchiha that shut the gate gaurd and anbus went there ways knowing very well the man is not harm to the village.
Sasuke entered the hokage office and saw kakashi, hinata and Sakura with her daughter as soon as his eyes laid over sarada his eyes softened and his lips curled upward and pink haired girl came and hugged him tight after releasing the hug he took his child in his hands and asked " looks like you all have been good, Kakashi how's your job treating you","well we are fine N as you can see my desk it's not easy" told kakashi "we are fine sasuke kun how are doing"Sakura "hello thanks, we are fine "hinata
"Where is Naruto I don't sense him did he come yet " sasuke, "you're the first to arrive sasuke I'm sure he'll come today only, last I heard from his toad messenger his training is really paid off and he had become incredibly strong what about you? How was your training go" Kakashi" my training is good I've grown strong you can see the fruits when me and Naruto fights", and they were talking and chatting with eachother about their life in last 5 years that's when sasuke felt the incredible chakra even though it was suppressed to normal civilian level because of his sage of six paths chakra he could sense
"Looks like he also arrived" sasuke with that lavender eyed girls smile got bigger and her face brightened and her son woke as though he has sensed his father or the strong chakra which only sasuke and kakashi noticed.
A portal appeared like a glitch or damaged part in movie or tv screens and the name of the space time technique is 'Amenominaka' a jutsu used by kaguya otsutsuki the technique also called as mother of all space time technique. Out came the young man in his early twenties with 6'10" height and body that is built for both speed and strength which every woman drool over and spiky white hair which come down to his back with two locks are over the red cloth he loosely wore over his forehead and a face that had no babyfat and a perfectly with a megawatt smile his oceanic blue eyes are now turned into ethereal blue and he wore white shirt over mesh shirt and dark red pants and a pair of ninja sandals and he strapped a small tanto which looked like inverted spear and he wore a haori with black and orange flames licking the bottom of it that reached just below his knees and on his right hand he wore small toy like gunbai,a gourd, axe hammer,a bow and a sword with both his hands wearing custom black fingertip gloves totally the young man looked like a god. Just like for sasuke anbu and gate gaurds perked up even though they can't feel his chakra they could tell he's very strong by seeing how he carried himself. When he entered he greets the gate gaurds but didn't register instead he climbed up the nearest pole and announced "I'm back" that's when the gaurds realised who he was, he is the hero who brought end to the fourth great shinobi war and his name is Uzumaki Naruto.
Naruto p o v:
As soon as he entered, he saw gate gaurds greeting them he climbed the nearest pole to take a look at his beloved village and proclaimed that he is back. After looking at the village he remembered what had all happened in last five years before he gone, he awakened sharingan and mangekyo sharingan at the same time with the help of sasuke by putting him in tsukiyomi' and making him suffer from all his trauma over the years and that helped him in two ways it helped him awaken his sharingan and mangekyo sharingan and it helped him to come to terms with everything and he accepted his trauma and became newself. After that he left taking every scrolls and books given by tsunade,sarutobi and jiraya and his parents and uzumaki after that he first went to the home of uzumaki, uzushiogakure after meeting tazuna and his family there he found many things fallen uzumakis sealed so the enemies can't get them and he sealed them in his sealing scroll and started training there he daily created one lakh clones which he was also surprised to find after containing all Biju his chakra has grown to new level and he doesn't need use his chakra to suppress them since they're willingly sealed in him. All those clones in first month made his chakra control the very best anyone had ever controlled using many chakra control methods,while his clones do the chakra other stuff he would use very heavy weight using fuinjutsu that he is at sixth level within a month after.hearing about guy's exploits against madara made him fascinated and he wanted to yield more amazing results in just with taijutsu and his body alone so he would do taijutsu learning and fight against his clones and bijus when they are out, even though shadow clone dissipates after one hit the sheer number made up for it, as his control grew he was able to make more clones of himself. With his regeneration ability and all he was able to grow leaps and bounds physically in one month he had one tonne weight distributed all over his body and with four times the normal gravity he could move at the speed guy without weights and his chakra control has no rival not even Sakura or tsunade and the next three months were mastering all five elements and with the help of his almost 2 and half lakh clones he mastered all 5 basic elements to new level like not even requiring handsigns to a jutsu but uses them not wanting to get bored and he has surpassed all greatest users of each element.at the end of six month he had mastered thousands of jutsu atleast two hundred to two fifty jutsu per each element genjutsu and other things after he went to the part of his sharingan and combining elements.another year passed now it has been 1 half year since coming and year starting his bloodline training in that time he had mastered all combining aspects and made a major growth and his mangekyo turned into eon mangekyo with 6 ninjutsu,genjutsu and time space jutsu like amaterasu,divine rain, celestial judgement, Malevolent slash,maze fort and exponential.Tsukiyomi, kotoamatsukami,
Probability, Izanagi Izamani(without weakness),drunken dreams of totsuka and Interrogatorrer. Kamui, Freeze Rewind, swap, weapon master and yomotsu hirasaka. After training with all of them after 8 months ago he activated rinnegan and rinne sharingan because of all the Biju presence his rinnegan gave him Deva,Asura,Animal,Preta, Naraka Human paths ninjutsu chakra molder, genjutsu nullify and limbo and his rinne sharingan abilities are precise absorb,copy, kaguya's six dimension,mirage and six clones,reversal. And he was mastering his kekkai genkai he got news that the moon is falling and hinata has been kidnapped.so,he took of directly to moon and met with Sakura,Sai, shikamaru and others went to take hinata back using his newfound skills and power he easily defeated Toneri.
During the battle one of his technique absorb which automatically absorbed toneri Tenseigan mode chakra that again changed his body his two eyes became rinne sharingan,and in his forehead is now a rinne Tenseigan and two rinnegan in each palm. Before all byakugan could consume toneri, Naruto and hinata saved him even if they were.because of that Toneri gave both Naruto and hinata gift which he didn't mention.after hinata confessing her feelings they both made love and he left them to complete his training and after that in another 3 and half year hear he mastered everything he had at his disposal he awakened susanoo which he had totsuka blade and yata mirror also he trained in its speed, reaction speed and variations in it and used Biju mode to further strengthen and at end of 5 years he's as fast as light without weights and his taijutsu his flawless and comfortable and his sage mode he perfected to not needing so6p mode to sustain it and he amassed chakra from first day at the end of the fourth year his chakra surpassed even that of jubi itself and what remained of the collected chakra he shared with all the Biju and they also grow very strong before 60 meter tall Biju now tower over 1000 meter in size as big as jubi and got mangekyo sharingan themselves now shukaku is as strong as kurama,matatabi is twice as strong as shukaku, isobu is 4 times, son goku is 8 times, kokuo is 16 times, saiken is 32 times, chomei is 64 times, gyuki is 128 times stronger than shukaku, while kurama now grown thrice as strong as jubi but when come out of seal they retain only half their size and newfound power.
So daily fighting the Biju while traveling places, meeting and making friends, training,growing stronger, he went to mifune to learn kenjutsu.for all in five years he has mastered every ninja art that is there and become so strong very few can fight him in real battle.
Remembering all of that made him happy.and jumped from pole and landed on ground and people who recognised him cheered him and he started walking towards hokage tower greeting people on the way.
When he entered the office he was greeted with the presence of 6 members his team and a woman he shared bed with but other two he didn't recognise although he could sense their chakra to find out he didn't wanted ruin the surprise and it would be invasion of privacy.so,after familiaring with them when he found out that he has a 3 year son and hinata didn't inform it made sad but understood the meaning and after few hours of talking he decided to marry hinata after few days since they already have a child.
