Four years passed since the Fourth Ninja War, and now the world is more or less in peace, the five great ninja villages are more united than ever, the loss of life and the sense of camaraderie of the last war united them all together, right now the only constant threat is that of the Hollow that keeps being born, but on the good side now all the ninja are more focused on fighting the Hollow then among themselves.
In the Baransa HQ in the Land of Whirlpool, Ren is looking at the letters he received from the other members that are outside of Konoha, then letting out a sigh he says "Haa... to think that Zabuza has gone back to being a ninja and is now leading the Anti-Hollow division of Kiri... I thought that he would slow down after marrying Mei and having a child... Instead soon after they both returned to their duty, luckily they spend most of the time in the village so the little Yukio still spends a lot of time with his parents... And when they are too busy, there is Haku who became a full-time babysitter/teacher for her...and hell Zabuza's daughter is a monster on her own... She inherited her mother's Lava Release, but she got Wind Nature instead of Lightning, and she is able to mix them into Ice release...at the age of 3 she is already able to minimally use both..."
Then he looked a Dosu's letter "Instead after the war, Dosu went back to Oto and gained control of it becoming its Kage, then he gathered all Orochimaru's victims that didn't have a place and together they formed the first village specialized in hunting Hollow, in fact, their tactics, training, and formations, are often being used by the other hidden villages to build their own Anti-Hollow squad, another new is that he decided to tie the knot with one of Orochimaru's victim that we saved before... A certain Guren who has an extremely rare Crystal Release".
After saying that, he read Yakumo letter with a smile, then he says "Really who would think of those two together... Yakumo and Jugo are traveling all over the world to enjoy the nature, make paintings, go on dates, rescue small animals and villages, gathering information on dangerous Hollow or organizations... like that fucking Kara that we were able to eradicate two years ago... really to deal with that off shot Otsutsuki I had to pull him into Naraka, release my limiter and use Yukai to kill him... hell I even damaged a part of of the Naraka and as aftermath, I had to stay there for a few months to repair it, a few months without sex! Fucking Otsutsuki!!... But the good thing about Zanpakuto is that they make it so that the Kama is useless as the Otsutsuki soul is purified and sent once again into the cycle, and without the soul, the seal can easily be purged".
Then he shook his head when he read Taro and Jiro's letter "And the twins hunt for girlfriends is still unsuccessful... they are searching all over the Ninja world for one, but let's say they are pretty famous as the Twin Streakers, as the accident that happened during the war where they forgot to cover themself after their fusion time is over, plus the photographic coverage of the event that was spread by a mysterious person... but jokes aside they are going around as intermediary with ninja world and the others shinigami of the Baransa...".
Yes, Ren started slowly rebuilding a Shinigami's organization in the Pure Land, he gave a small piece of his power to a soul to nuture, so that it can form its own Zanpakuto, once that happens, the power he gave came back to Ren and he can do this process once again, right now only Ren can do this, but when the first batch reaches the Captain/Hokage level they can do so in his place, right now the new generation of Shinigami are, Minato, Hashirama, Kushina, Tobirama, Nagato, and Sakumo, the other in the list to recruit are other notable and honorable ninjas, right now they sometime come back to earth to deal with Hollow there and pass some limited time with their families, the first time Naruto saw his parents he thought he fell into a Genjutsu, then he cried for and laughted for an hour, and of course, Hinata got Kushina's seal of approval.
Then Ren looked at the letter he got from Yahiko, and he is stunned by what he read, so much that he stood up and yelled "What the....!? TSUNADE IS PREGNANT!!!?", Yes Tsunade and Jiraiya finally got together soon after the war, as she once again lost her bet, she then decides to retire as Hokage and the two started traveling and enjoy their time together, then three years ago they were called by Yahiko to Ame, as he needed Tsunade's help and he didn't trust the other medic in the village.
To make the long story short, after the war, Yahiko and Konan went back to Ame, and took control of it, at the same time the old passion they had relinked and the two married, and a year later Konan is about to deliver their first child, but seen Konan age, Yahiko got overly worried and asked, Jiraiya for help and so the two went to Ame, after helping delivery the little Nagato, the two practically became the child Grandparents and chose to settle for a while in Ame with them, and now after three-year living there, now is Tsunade that is expecting at the young age of 59.
Ren once again sat down and says "Really those two... Luckily thanks to Jiraiya's Senjutsu and Tsunade's medical ninjutsu they both can live a really long life...", then Ren thought about the others "In the end after Tsunade resigned, Kakashi became the Sixth Hokage, Kabuto, went back to taking care of the orphanage, together with Mecha-Naruto that became the children's Hero, hell they are making a mecha anime out of him... yet another random jump in technology... Sasuke is dating Sakura, and he is of course treating her well, after all he he doesn't or pull something like the original that he knock her up and escape, I'll spread to the world all his photos in the Hall of Shame, something I warned him about... And now, they are preparing to live together and marry..."
Then as he walked toward the Hall of Shame to check and update its content, he continues "Almost the same is happening to the other couples of my generation, Ino and Sai are dating for a while now and they too are thinking about marrying, Choji was able to conquer the fiery Karui from Kumo and she is now about to become a full Konoha citizen, and the same is happening with Shikamaru and Temari, talking about Shikamaru he spends most of his time now helping Asuma and Kurenai teaching the little Mirai about the basics, and helping her schoolwork as she is 5 years old now".
Entering the Hall of Shame, Ren checks the barrier he placed and saw that they were still standing "Good, it's hard to make a Rinnegan proof barrier, soon after the war Sasuke tried to send this room in another dimension and almost succeed, I had to use my Yin Bankai to put him to sleep and stop him, of course the photo of him sleeping sucking his thumb with a cool face entered the collection, but if this goes on, I'm afraid that one day if the content of this room gets out, Sasuke and Itachi will use the Infinite Tsukuyomi to make the world forget about it".
Then he looks at another photo pinned on the wall, in this one Sasuke is stalking his brother on his date with Ayame the daughter of Teuchi, and of Itachi stalking Sasuke on his first date with Sakura "...Really what a pair of brocon..." and the photo of him stalking them to take this photo "...Really Peri became a master of this art, even with my senses I didn't felt his presence then, he really is one with the nature!", then he pulls out another photo and pin it on the wall, in this one there is the image of Gai standing on his feet hugging and kissing Kakashi's cheek "I forgot to put this one, this was taken after I used Kaido to heal the damage the recivied from opening the Hachimon (Eight Gates)... Really sometimes those two worry me a little, they are close... like really close... and still single... better not think about it".
Ren looks at the photo of Naruto when he found out that he can't become a Hokage as he was still a Genin and that he has to become a jonin to become a candidate and says "Naruto and Hinata in the end still became a couple, and they are the third of our generation to marry, the fourth are Rock Lee and a civilian girl from his neighborhood, while the second are surprisingly Neji and Ten Ten... Talking about Neji, me and Karin created a new seal to protect the Byakugan and practically forced the Hyuga clan to use it, so the Branch clan is no more needed, there were some hostilities soon after but with Hinata and Neji working together, in the end, everything went for the better, in fact, Neji is now the new patriarch of the Hyuga clan, as Hiashi helped in suppressing the elders' opposition, and in just 4 years the Hyuga clan is stronger than ever".
Then just as Ren closed the door of the Hall of Shame, a small Senkaimon opens and a Jikogucho flies out of it and lands on Ren shoulder, and the next moment, Ren expression turn deadly serious, he quickly runs out of the HQ and uses the Bakudō #87. Sentan Hakuja (Thousand-Coil White Snake), to quickly teleport near to Konoha, then he uses Shunpo to enter the village and starts jumping from roof to roof.
Suddenly he stops and turn into another direction, and arrives in front of a flower shops with a sign that tell "Yamanaka Flower Shop" rushes inside and yells "Ino! Can you give a bouquet of lilies, iris, and dandelion please as soon as possible!" Ino smiles and quickly prepares his order as she says "Is it finally the day? You look nervous, calm down everything will be fine, after all the best medic ninja of our time is next to her..." then she gave the bouquet to Ren and says "...This is on the house hurry up, but be careful".
After saying thanks Ren once again rush out and runs towards the hospital, on his way he meet up with a family of three, they are Hayate, Yugao and their 6 years old son Mikatsuki, who as soon as he saw Ren yelled "Sensei! I did it! I was able to use the Onibi (Oni Fire) you taught me, stunning everyone at school including Shino-sensei" and Ren still running replies "Good job, Mika! This weekend I will teach you the basics for Hitotsume: Nadegiri (The First: Killing Stroke)! Have fun with your parents!".
Soon Ren reaches the Hospital goes inside, greets the receptionist, and enters his wife's room, what greets his sight is the view of his wife Karin getting ready to give birth, he goes near to give her the flowers and kisses her on the top of the head and with a charming smile said "You're sexy and you grow it...", but before Karin could say anything, Sakura punches Ren on top of his head and says "Don't be like dad and pull out puns at the most inopportune moments!", hearing that Ren nods and says "Ok, bloomer... Ops sorry too nervous...".
Then after a few hours of screams, a chain tentacle-like play, and a few broken bones, finally the child is out, and in the embrace of his mother, Karin, who while exhausted, has a happy and peaceful smile on her face and a beautiful boy with crimson eyes and a small tuff of raspberry pink hair in her embrace, and thanks to her Uzumaki constitution plus Ren's Kaido and Sakura medical ninjutsu is already recovering.
Next Ren hugs Karin and his child and asks "Dear, what do you want to call him?", Karin looks at her child and sees him looking at her with his crimson eyes and says "Let's follow our family tradition... His name will be Haruno Riku!".

Afterword
This is the end guys, I've chosen a more open-ended one, in case I want to make a sequel in Boruto Era, I admit that this isn't a masterpiece after all is my first work, but at least it should be a good one, and more importantly a complete one, I have read too many good fanfict with a very good potential that stops as soon as they reach 20+ chp, while this could be short for some it is still a 200.000+ word work bigger than a book of Harry Potter so for me good enough as a start, but enough ranting, THANKS EVERYONE for reading and appreciating my work and for those who gave their encuragament, see you in the next fic, it should come out, in the coming month (When I have 30+ chp ready) a little spoiler the next one will be a multiverse one, and I will try a different writing style, 1st person, less detailed description of characters, and imgs as support. Until the next time see you soon and Have Fun Cya.
