I do not own the characters (they are owned by Masashi Kishimoto).In this story Naruto and Tenten are both 18.
Sixth Hokage Naruto Uzumaki Namikaze was on his way over to the forge that Tenten's father owned in the late afternoon. He was currently wearing his Hokage cloak which was an orange cloak with black flames and red markings on the collar similar to the ones on Hagomoro's cloak. His cloak also the kanji for "Sixth Hokage" on the back along with the symbol of the Uzumaki Clan above it.
Tenten had run into him earlier today and told him to come by her family's forge later on that day to pick up something that "belonged to him". Although she wouldn't say what it was, she simply said to him that it was something that her father had said was meant to be given to him a long time ago.
"Well after everything I have been through in the war, I'm guess I should be used to surprises by now." Naruto thought to himself smiling as he thought about how the war had been won. Naruto and Sasuke had finished off Madara Uchiha after the two of them had been gifted with Hagomoro's chakra.
Naruto had managed to pull all of the tailed beasts from Madara as well as the Shinju chakra he possessed which was added to his own Shinju chakra that he received from a redeemed Obito Uchiha. He then used the combined chakra of the tailed beasts as well as Hagomoro's chakra to activate his new Senjutsu of the Six Paths chakra cloak which made him look like a mirror image of the Sage.
Sasuke meanwhile had awakened the Rinnegan in his left eye after receiving Hashirama's cells from Kabuto who arrived to save Sasuke's life to repay Sasuke's brother Itachi for showing him the error of his ways. His newly awakened Rinnegan merged with his Sharingan and this only served to enhance his powers.
Naruto then surprised his allies when Naruto was revealed to have awakened his own unique Rinnegan thanks to the combination of Hagomoro and the Shinju's chakra, and the chakra of Hashirama Senju given to him by the reincarnated Hokage himself. Naruto's version of the Rinnegan, which he called the Yin-Yang Rinnegan was colored black with white ripples from the influence from the Shinju's chakra.
But what ultimately proved to be the biggest shock of all to everyone (especially Madara and Sasuke) was when Naruto revealed his new Eternal Mangekyo Sharingan in both eyes that he had received as a gift from Obito Uchiha, who had given him his Sharingan as he transferred the tailed beasts to him to save his life and Itachi Uchiha who had given him Shisui Uchiha Sharingan before going to find Sasuke instead of destroying it and telling Naruto to use it when the time was right.
Naruto's two gifted Mangekyo Sharingan had then morphed into Eternal Mangekyo Sharingan thanks to the influence of the Sage's chakra and this gave Naruto the ability to summon his own completed Susanoo which took on the appearance of a giant knight with a demonic right claw and a demonic horn on its head. In its right hand was a giant gothic-looking zweihander.
Naruto and Sasuke destroyed Madara with a combination of Sasuke's Rinnegan enhanced Blaze Release: Susanoo Kagutsuchi that skewered the elder Uchiha ancestor before he was cleaved into pieces by Naruto's Susanoo sword. Naruto and Sasuke then proceeded to destroy his remains with a Chidori Sharp Spear/Lava Release: Rasenshuriken combination.
After Madara had been completely obliterated Obito Uchiha had used the last of his remaining life force to perform the Outer Path: Samsara of Heavenly Life Technique to revive all of the members of the Allied Shinobi forces that he and Madara were responsible for killing as well as the deceased jinchuuriki.
Then much to Naruto's surprise Kabuto used the last bit of his life force to perform an Impure World Reincarnation in a similar fashion as Orochimaru when he reincarnated the previous Hokage to bring back all those who were killed as a direct result of Akatsuki's actions and Orochimaru and Kabuto's crimes before the reincarnated shinobi were fully revived by Obito's technique.
Obito and Kabuto died soon after and despite all the chaos they had both caused, Naruto would be lying if he said that he wasn't somewhat sad to see the two reformed villains die, but he took solace in the fact that they had both died as their true selves and not behind the masks that they had lived under for so long.
Sasuke returned to Konoha soon after and was reunited with Sakura and he and Orochimaru were soon pardoned for their crimes and were allowed to return to Konoha and as a form of compensation for how Sasuke's clan was wrongfully slain the Konoha Council was soon reformed with Koharu and Homura stripped of their positions and Sasuke was offered a spot on the council which he gratefully accepted.
As for Naruto he was celebrated as a hero in the five Elemental Nations and soon after he was rewarded with his lifelong dream of becoming Hokage. Soon after he was named Hokage, he later named Sasuke as the newly-appointed Captain of the ANBU like his brother before him along with naming both Sasuke and Sai as his bodyguards.
"Hey Naruto, you finally made it." a familiar voice said and Naruto looked up and smiled to see that he was at the weapons forge and standing in front of the forge waiting to greet him was Tenten herself.
The bun-haired brunette hadn't changed much in regards to her personality. She was still the same spark of energy that she had been since her youth. However that wasn't the case for her physical appearance. Her body had matured since they were younger and Naruto had to fight back a blush at the weapons mistresses' slender, toned figure.
"Um Naruto, are you still with us?" Tenten giggled as she snapped her fingers in front of his face to bring him back to the realm of the cognizant.
"Y-Yeah, sorry about that. So what did you say you had for me?" Naruto asked the weapons mistress.
"Follow me and you'll find out." Tenten said and she turned and led Naruto into the forge where they both came face-to-face with Tenten's father.
"Ah, Hokage-sama. Glad you could make it." Tenten's father said as he smiled at him.
"Thank you very much. So Tenten tells me you had something that belonged to me?" Naruto asked the weapons master.
"Oh, yes wait here for one moment, Tenten would you come with me please." the man said and Tenten followed her father to the back before they returned moments later holding two boxes. Tenten was holding a long and slender black box and her father was carrying a large blue box that he was looking at with a reminiscent expression on his face.
