New World

' I've learned everything i needed from Orochimaru, it's time to get rid of him. ' Sasukes red eyes shined brightly, the danger in his eyes showed his intentions as he got up to find Orochimarus room.

" Where are you going? " Kabuto asked randomly appearing in front of Sasuke.

" Does it matter to a simple Maid? Or do you wish to die? " Sasuke asked slowly taking out his blade as electricity covered it.

" No I don't, Orochimaru is in bed so you should at least let him know. " Kabuto said with a smile looking at Sasuke stop before putting the sword back.

" He's going down this hall to the right, the door is open so it should be fairly obvious which room he's in. " Kabuto gave direction before leaving.

' Looks like i was going the wrong way, thanks for the information. ' Sasuke took out the sword again as he followed the direction but suddenly he saw a big blue portal.

" What the hell is that? " Sasuke looked at the massive portal covering the whole space with curiosity, quickly cutting the wall he grabbed a piece of concrete before throwing it at the portal.

It swallowed the piece instantly, it didn't explain much at all so he was thinking of entering.

" Is Kabuto trying to set me up somehow? " Sasuke asked himself, 

" Whatever it is, I'll destroy it. " With pride and confidence in his abilities he entered the portal with his eyes red and his sword covered with lightning.

...

[ You will now receive the necessary memories! ]

" What is this place? " To Sasukes shock a whole new world seemed to be where the portal sent him, Building he's never seen before, Cars, technology, people running around in costumes, what's going on?

[ Please try your best to endure the pain. ]

" What are you- GAHHH " suddenly a massive pain entered his head and eyes, his eyes were burning hotter than ever to the point it felt like they would melt, and his brain hurt so much it could break at any moment.

" What the hell this?! " Sasuke yelled as the pain continued the same as his screams.

After half an hour the pain finally stopped but Sasuke still hadn't recovered from it all, 

[ The memories have been given, please choose 3 characters to combine with you from your world ]

" Is my world not real? " Sasuke asked himself as he laid in the grass tired, he didn't even feel like sitting up.

[ All worlds are real and not real at the same time. ]

" That doesn't even make sense. " Sasuke closed his eyes as the memories settled down and he looked through them.

He received 3 different memories, The first was of the future him who fought someone named Kaguya along with Naruto. His whole future was played from beginning to end, his brother dying, the group he created, Narutos accomplishment along with his own, his growth, everything.

' It seems with those memories i was gifted the powers i had gained. ' Sasuke covered his right eye that had turned purple, The Rinnegan. 

The Second was the memory of a kid who came from a world called earth, in their world Sasukes world is called " Naruto " and is a anime, but that isn't really what matters as apparently he wished to take over Sasukes body so he was moved to MHA another anime as the kid took his spot. The boy apparently didn't read or watch MHA and has only seen glimpses or spoiler from something called Tiktok.

" What a useless kid, if he manages to survive at all I'd be surprised, especially in a world where there's no kinds of abilities, still it seems this world could be stronger than my world, This all might seems to be as strong or stronger than Tsunade, A Kage. "

And the last memories were the body he took over, he still has his face, body, and clothes he had before entering the portal. He seems to have no parents, or family members so I don't have to worry about any reason to act like the kid. 

" Still he was planning to enter this school called UA, this world is very different so i should follow it's rules to an extent if i want to live comfortably. All my plans gone down the drain because of a kid who wanted to be a anime character. " Sasuke got up and was ready to follow the directions back to his house in this world before being interrupted.

[ Please choose 3 characters to combine with you ]

" Ah i forgot about that...As a tribute to my brother i would like to choose him, his abilities would boost my own as well. As for the other two I'd like to choose Kaguya and Tsunade, Kaguya gives me all attributes in the world and a stronger base while Tsunade gives me perfect chakra control which helps quite a lot. " Sasuke explained receiving a answer quickly.

[ Characters granted, their abilities are now combined with you. The experience and memories of it all will be given to you. ]

Sasuke closed his eyes ready for the pain but instead it felt very smooth, his eyes, head, and body felt very warm as it finally went away after a few minutes.

" Thank you, Brother. " Sasuke said with a warm smile as he finally left towards his house.

...

" This world is very different from mine, Today is Wednesday so I'll have to learn everything by Saturday for the entrance exam. " With a goal in mind Sasuke open his sharingan and began researching for everything, after figuring out libraries had a lot of books to learn from he started visiting as many as he could.

He could read a 200 page book in 10 seconds, and if he only read the categories he needs he can knock out 2-3 libraries in a day. He also tried learning things that aren't taught in books through vutube or website where people explained it in high detail, by Saturday morning he had the knowledge he'd need for anything that could be asked. 

He didn't know how to feel about the boy he took over as he read a few reincarnation and transmigration novels when he got curious about his predicament, he found a diary of everything he wanted to do before dying so he promised to grant it as respects.

" I'll get first place no matter what, no one's going to stop me. " Sasuke told himself as he started walking towards the doors.

" Hey, i saw you just stand there for a few minutes, you okay? "

...

(A/N Incase anybody is curious why i didn't pick Naruto, it's pretty obvious. He has nothing useful, and Kaguya quite easily overpowered him and Sasuke at their strongest. Why go for a weaker character, Tsunade i already explained, her healing skills would be boosted even more with Kaguyas strength and bloodline, and Itachi boosts Sasuke Eye abilities and his Susanoo. )
