4 Sasuke Uchiha

"Time to enter the final dimension..."

Sasuke muttered as he appeared inside a forest from a portal.

Sasuke Uchiha, one of the heroes of the Fourth Great Shinobi War had a complicated history.

As the weilder of the Rinnegan, he was able to master a teleportation technique, to make portals to enter different dimensions. So, he was the only one who could go and investigate the dimensions of Kaguya, and to get any information he could on the other Otsutsukis she was so afraid of.

Out of her six dimensions, he has just completed exploring her 5th dimension.

Sasuke sat down under a tree, finally relaxing after exiting the Gravity Dimension after a year of exploring it. After the lava dimension, it was the hardest to explore.

In the lava dimension, he had to let the snow from the ice dimension to freeze it, and then explore it with his Rinnegan. He found some clues on a mountain there, so it wasn't out of possibility that he may find more clues in other dimensions.

And the one he just exited now, was only possible to explore using the Deva Path of his Rinnegan to manipulate the gravity around him to move. But when he ran out of chakra, he had to suffer the intense gravity on him while sticking to the ground.

It was by far the largest planet, made out of heavier substances than the earth.

"It's been almost a year..."

"No. It's been ten years."

Sasuke was surprised by the fact.

"You are looking old, Naruto."

Sasuke turned around to face Naruto, who was shocked by the age difference between them being so apparent. Naruto shook his hand, shock apparent on his face.

"You are looking too young, Dattebayo!"

So time flows around 10 times slower than the Earth, huh.

Wait a minute... If 10 years has passed by, then Sarada-

"Yeah. Sarada is 12 year old now, and has recently become a genin."

Sasuke wasn't ready for that!

If Naruto wasn't pranking him, then this means that not only he hasn't met Sakura for a decade, who has grown to be a decade older than him, but also his daughter probably doesn't remember him, and has grown up without a father.

"Hehe!"

Naruto laughed, and poofed to be looking like a 25 something young man.

Sasuke took out his sword, and charged it with chidori.

"I am going to finish what I started at the valley of the End, NARUTO!"

"SASUKE!"

Both Naruto and Sasuke charged at each other, and suddenly, Sasuke jumped up as a Naruto's hands came from the ground to bury him.

He will never let Naruto of all people to humiliate him like Kakashi did.

He would have used Amenotejikara to swap places with Naruto to bury him instead, but he needed some time to recharge his Rinnegan's visual poweress after exiting that dimension.

But suddenly, Naruto appeared in front of him with a Rasengan, as if he has teleported.

"Rasengan!"

Sasuke barely blocked it with his Susanoo ribcage, but went flying due to the impact.

Naruto appeared in front of him again, with a Rasengan. But just in time, Sasuke's Rinnegan was recharged enough to use Petra Path.

A barrier appeared, and it started absorbing the Rasengan.

"So, how about Sage Mode?"

As Naruto went into Sage Mode almost instantly, Sasuke used Shinra Tensei to push Naruto away.

'I have enough chakra.'

Sasuke looked at the tree beside him, charged his chidori, and used his unique Rinnegan ability.

'Amenotejikara'

Naruto appeared in place of the tree, with his feet buried in the ground.

"NARUTO!"

Naruto formed a Rasengan.

"SASUKE!"

"BOTH OF YOU! STOP!"

Sasuke saw pink as the person caught his chidori with bare hands, and Naruto's Rasengan as well, and threw both of their jutsus in the air.

*BOOOOOOM!*

The three of them looked at each other, and started laughing.

Oh how times have changed. Some years ago, Sasuke and Naruto were fighting using the same Rasengan and Chidori, and Sakura almost got killed to stop them by coming in between, and he was not experienced yet to stop.

And now, both him and Naruto, were just having a friendly battle instead of a fight using Rasengan and Chidori, and Sakura had enough of them so she threw away their jutsus.

He looked at Sakura, and she hadn't changed from the last time he saw her, and Naruto too. They both looked around 25 years old, who just had their kids.

That Naruto, he scared him.

"I am back."

Sasuke Uchiha was back.

****************

"Dad!"

A 12 year old girl gave Sasuke a hug as soon as Naruto teleported Sasuke and Sakura home.

"Ahem! I have to return to calm down Boruto, so, bye!"

And Naruto disappeared.

...

'NARUTO!'
