Visitors from the future

Time soon passed by,

Naruto soon began to train the Flying Thunder God thanks to his shadow clone cheat and was making steady progress in learning it since he had time space affinity like his father while Sasuke was still doing physical conditioning because his body wasn't strong enough to withstand Lightning chakra.

As for Karin, She now began to learn more medical knowledge and preparing to learn the Yin seal.

Two men then appeared in Konoha, One of them was a blonde 12 year old who had whiskers similar to Naruto while the other one was a tall black-haired man who had bangs covering his other eye.

They soon ventured into Konoha and bumped into Naruto who was running away with Jiraya after they got caught peeping.

Tsunade who was pursuing JIraya and Naruto then noticed that these two people were trying to get close to Naruto but since they weren't in the Akatsuki file that was anonymously donated, she decided to be lenient towards them and soon called Tetsuya to monitor the two of them.

Tetsuya who saw the two people immediately went to punch the blonde kid on the head for some reason which startled everyone present.

"Uh! Sorry I had a sudden urge to punch that kid as soon as I saw him."

Everyone present just shrugged it off since no significant damage was done except for the blonde kid who showed an angry expression at Tetsuya.

Goddamnit. I didn't want to think about Boruto's plot at all.

As all of them separated, Tetsuya asked tall black-haired man to have a private talk with him which he accepted.

"Well then, Uchiha Sasuke from the future. Do you know me?"

Sasuke was startled that his identity was leaked on the first day when he arrived but after thinking for a seconds he decided to respond truthfully

"No, I don't know you." Sasuke responded

"Well then, you're not in your original timeline but in a parallel timeline in which some events that should've happened have changed greatly.

You didn't defect in this timeline and you weren't in the same team as Sakura so I'm sorry but you probably won't be Sakura's husband in this timeline."

Sasuke then began to think and soon asked about what Tetsuya knew and why did he tell him.

"While I don't know everything, I most likely know more than you about the Otsutsuki threat that your timeline is facing. I also know most of things that happened in your timeline since it's supposed to be the original timeline while this timeline was greatly changed by me.

As for why I told you, I leaked the Akatsuki's information to the Hokage but she doesn't believe it fully. I would like you to reveal your identity to her and help me convince her since whatever you do here won't have any repercussion on your timeline."

Sasuke accepted to help after he considered his options and soon began to ask about what Tetsuya knew about the Otsutsuki.

While Tetsuya knew about Otsutsuki Isshiki, he didn't know much since he just skimmed through the anime and manga just to give it a fair chance but he gave up halfway because all he could think while reading was that they ruined Naruto's ending to make this sequel.

Tetsuya then began to talk about Urashiki's powers and Isshiki's presence which greatly startled Sasuke.

After all was said and done, adult Sasuke and Boruto went to Tsunade and Jiraya to reveal their identity without mentioning Tetsuya's existence since Tetsuya requested that he didn't. 

After explaining what would happen in the future, JIraya was relieved that he didn't barge in Amegakure. Jiraya was also surprised that the child of destiny he was searching all along was Naruto.

Tsunade was also satisfied after hearing that Naruto became the seventh Hokage.

They pretty much confirmed the information of the Akatsuki that they had and decided to make a plan for the future.

Naruto and Sasuke were unaware of what they talked although what was talked was mostly about them.

But for now, they prepared to intercept Urashiki who would arrive in a few days.

Adult Sasuke then approached Yuzume since he was made aware that another Uchiha survivor existed. After adult Sasuke revealed his identity to Yuzume, the two of them soon had a talk about Itachi.

Yuzume didn't have much enmity with Itachi since he didn't have a loved one in the Uchiha who but he still decided to take revenge since it's his responsibility as the current Uchiha clan leader to avenge the Uchiha who died during the genocide.

After discussions, they decided to reveal the truth to Sasuke so that he could make a choice of his own since he had different experience from adult Sasuke.

Sasuke who finally knew the truth finally awakened the Mangekyou. He still decided to kill Itachi since that was his Itachi's wish anyway and he didn't approve of Itachi's method to kill everyone else to let him live.

Sasuke didn't bother trying to take revenge either since Yuzume and Tetsuya already killed Danzo who was the mastermind. And adult Sasuke convinced him with his words since he was himself in the future.

…

Soon enough, Urashiki appeared to attack Naruto but this time, they were prepared to intercept him. Tetsuya gave adult Sasuke thorough information about Urashiki's powers since the Urashiki arc was one of the very few episodes of Boruto that he watched without skipping.

Adult Sasuke, Jiraiya, Tetsuya and Naruto were present in one place to bait Urashiki to them.

As soon as Urashiki approached, Jiraiya used the Toad Mouth Bind to entrap him within the stomach. Urashiki was arrogantly shrugging off the fact that he was trapped.

Tetsuya then ordered Naruto to send clones to attack in order to waste Urashiki's time and permit the poison emitted to seep into him properly.

Urashiki who was unaware of their plot just stood there arrogantly waiting for Naruto to tire out but after 5 minutes, the poison finaly took effect.

As soon as Urashiki coughed blood, Tetsuya immediately used the raigo rasengan to directly attack Urashiki's head.

Urashiki then died without even being able to implant the Karma on someone.

Tetsuya was a little sad since he could've gotten a rinnegan if he didn't blow up Urashiki's head but he soon gave up sulking because he knew that he couldn't bear the strain caused by it. Even Obito who was implanted with white Zetsu cells was only able to withstand a single rinnegan and Nagato's vitality was slowly eaten away by it.

….

Adult Sasuke decided to train his younger self a bit while Naruto who was still clueless that Boruto was his son just hung out together. They never revealed it to Naruto since things would become awkward with Hinata if they did.

Adult Sasuke also tried to promote Sakura to his younger self but he didn't get any results because all of young Sasuke's experience with Sakura was just her annoying fangirling over him since they never developed any friendship like in the original.

Adult Sasuke also wanted to see Itachi for the last time but decided against it since it would just make him sad afterwards.

After a few days, they finally left for their own timeline and the others soon came back to their daily Lives.
