Ninja Academy
'My name is Uchiha Sasuke. I am nine years old and am the orphan of the Uchiha Clan. Just a few months ago, my entire family was massacred by her. I could only lie in the blood of my family as Genjutsu took hold of me and I became unconscious.
Since then, I have nightmares every day. But even with my clan exterminated and my family killed, I only opened a Two-Tomoe Sharingan, and even then I can't keep it active for long. Every day I dream of taking revenge, killing that bastard, but ultimately I am too wea—'
Just when Sasuke was dreaming of taking revenge for the hundredth time, he was stunned by the scene outside the classroom window. His brother, Uchiha Itachi, was standing beneath a tree waiting for someone.
Seeing the hallucination, Sasuke pinched his hand, waiting for the pain to wake him up. The pain did come, but he could still see Itachi.
'Is this the new Genjutsu of that bitch?'
As Sasuke rudely thought this, he opened his Two-Tomoe Sharingan and tried to disperse his chakra to wake himself from the Genjutsu, but he couldn't escape.
"Hey Sasuke, why are your eyes red???" Naruto, who was regretting not running away with Kiba in time, noticed the strangeness in Sasuke and shouted in shock.
"Uzumaki Naruto, do not dist—" Iruka, who was about to scold Naruto for creating another prank, stopped midway when he looked at Sasuke.
"You... do you see that person??" Sasuke ignored Naruto's unnecessarily loud voice and forcefully asked the nearby Ino.
"What... ah, there is indeed a person.... Doesn't he look like your bro—"
CRACKKK SPASHHHH
Before Ino could continue, the sound of breaking glass rang out as Sasuke jumped from the one-story-high window and rushed toward Itachi.
"Sasukeeee!!! Shikamaru, immediately go to the Vice Principal's office and tell them that Uchiha Itachi is in the Ninja Academy."
"Yes."
Seeing Iruka shouting while preparing to follow Sasuke, Shikamaru didn't act lazy and immediately got up. The Vice Principal of the Ninja School is an Elite Jonin, second only to the Principal, who is the Third Hokage. While Shikamaru ran, he thought of the incident a few months ago and wondered how Itachi was in the playground.

"ITACHIII!!!!!"
Itachi looked at Sasuke jumping from the building and running toward him while shouting his name.
'Still too impatient...'
Seeing Sasuke not even taking out a kunai, Itachi shook his head. Although Sasuke's expression was a little different, he could feel the unprecedented excitement and disbelief within him.
Indeed, in the original anime, Sasuke met Itachi only after his graduation, unlike now. Maybe after a few years he became more mature and calm, unlike now when he couldn't think of anything other than running toward him.
"Long time no see, Sasuke." Itachi smiled more gently than he had in a long time.
BOOMMMMM
The next moment, like a husky colliding with its owner, Sasuke hugged Itachi.
Itachi became confused upon seeing this. Where was the promised punch or kick? It's not that he was a masochist, but he was supposed to have a brotherly Taijutsu duel, then a Ninjutsu duel, and finally, after exhausting Sasuke, tell him the truth.
Now, everything was chaos....
Is this what you call a parallel world?
But sensing many people about to arrive, Itachi used Flying Thunder God to teleport to a distant mountain. Now he needed to calm Sasuke down and ask many questions in peace.
"Sasuke, I know you have many questions, but before I answer them, let me ask a few questions. They might be a bit sensitive, but answer truthfully."
"Okay, big brother."
Sasuke got off Itachi and finally nodded. He also felt that his big brother's presence was a bit strange, and he didn't know any jutsu capable of moving from Konoha to this mountain.
"First, what happened to the Uchiha Clan?"
"Brother, you don't remember?..... Nearly half a year ago, that half-blood bitch killed everyone in the Uchiha Clan. When I returned, father... mother... and everyone else were dead. She was about to kill me as well, but you arrived between me and her sword and finally made a deal with her to save my life. Later, I became unconscious, and since then I have been training to get stronger, kill her, and avenge everyone."
As Sasuke said this, his Two-Tomoe Sharingan rotated.
"Big brother, did you escape death by any chance, or did her stone heart have even a bit of mercy?"
Sasuke questioned him after noticing Itachi in a daze.
Itachi really was in a daze. He had died in this world while protecting Sasuke.
"Who is this 'she'?"
Noticing that Sasuke hadn't said the name even once, Itachi asked curiously.
"That bitch.... the half-blood of the Uchiha Clan.... Uchiha Izumi, your.... girlfriend."
Five Minutes of Silence
Itachi looked at the beautiful mountains and valleys in a daze.
He had expected many answers, but this was the last answer he expected....
Izumi exterminating the Uchiha Clan?
"Big brother, can you answer my question now?"
"Sasuke, I am not Uchiha Itachi.... or at least not the one you know. I am not even from this world. I am from... another world, a parallel world that has some history similar to yours. I awakened my Mangekyo Sharingan, and while discovering its power, I arrived in this world."
"Does that mean everyone in your world is still alive?"
Sasuke asked with envy.
The feeling of losing everything within a single night....
He hated it to the core.
"Yes. The Uchiha Clan in that world is the strongest clan. I am now the Uchiha Clan Patriarch. The Sasuke there is also the same age...."
Hearing this, Sasuke became a little distant.
This Itachi was not the one who had given his life to save him, and this Itachi would eventually leave.
He didn't want to form any new bonds that would eventually break.
"Sasuke, do you want to travel to my world, where you still have your family?"
Itachi noticed Sasuke's expression and asked with a smile.
He had another, better way—to revive all the Uchiha.
But he couldn't for now.
Just like the card introduction said, the greater the interference with the plot, the less time he could stay.
Simply giving the three items and advising Kiba had reduced his total time by more than a year. This was also one of the reasons he didn't directly destroy Konoha.
If he went and revived Fugaku and the others, even without the Sage of Six Paths' interference, his time would most likely run out before completing the task.
That's why it was better to take Sasuke to Mizumori until he found another way to travel to this world without restrictions.
"They are not my family, and I still have to avenge big brother, mother, father, and the others."
Sasuke spoke coldly.
"And how do you expect to become strong enough to defeat Izumi? By going to the Ninja Academy and playing ninja games? Only an Uchiha can defeat an Uchiha. Konoha will only make you a breeding pig after you grow up and recreate the Konoha Uchiha Clan...."
"I... I can also awaken the Mangekyo Sharingan."
"How?"
Two Minutes of Silence Later
"Sasuke, how about this? At your age, I was already a Chunin and could perform dozens of jutsu. Just show me three jutsu, and I will tell you the secret of awakening the Mangekyo Sharingan, along with all the clan jutsu and secrets."
Hearing this, Sasuke immediately became excited.
He had been practicing intensely all these months, and finally it could be useful.
"Okay."
Snake → Ram → Monkey → Boar → Horse → Tiger
Fire Style: Great Fireball Jutsu
As Sasuke shouted, he opened his mouth and a huge fireball started to form.
SWOOOSHHHH COUGH COUGH COUGH
Just when the fireball was almost complete, it got out of control, and Sasuke started coughing black smoke. Without proper chakra support, the uncontrollable fireball gradually dissipated into nothingness.
"I... I will try again."
Ten Minutes Later
"Sasuke, look. You can't even perform a single ninjutsu. How can you think of defeating a Mangekyo user with this meager strength?"
Hearing Itachi's teasing, Sasuke glared at him angrily, his Two-Tomoe Sharingan rotating as if he wanted to burn that bastard into nothingness.
"You do not even have a shred of shame. Using Mangekyo Sharingan to hinder me?"
By now, Sasuke had come to understand that Itachi was preventing him from completing his ninjutsu.
The only reason he kept trying again and again was to prove that even with Itachi using his Mangekyo Sharingan, he couldn't remove the teeth of a tiger.
Now it seemed he had underestimated the Mangekyo Sharingan too much.
"When can I come here again?"
"Well, I am not sure.... You see, this time I came here accidentally. The next time I come here might be in a few months, a few years, or maybe never. Though, you do not have to worry. I will make sure that all the perpetrators of this disaster are dealt with."
"Noo.... I will take my revenge myself."
Hearing that Itachi was snatching away his chance for revenge, Sasuke shouted angrily.
"Weaklings have no opinion. Though you still have a few years before all the perpetrators die, so become stronger faster and wish me luck. Either way you choose, luck plays a major factor, so why not go with me?"
Sasuke clenched his fists.
Itachi was right.
Either way, it all came down to luck.
In the Ninja World, no one knew what came next—tomorrow or death.
"Okay, I will go with you."
"Hmm, then wait for me in Konoha for a few days. You can say goodbye to your friends and visit father and mother before we depart."
"Are you going to meet that half-blood?"
"Indeed, I have to know the complete story, right?"
"Hmph."
Itachi smiled at Sasuke's anger and, the next moment, teleported to a nearby forest outside Konoha.
"Sasuke, here's a few Haki Knots. If someone bullies you, untie one. The next moment, a gravitational domain will form around you, rendering most people unconscious. And here's Sagittarius's projection. If someone forgets the fear of the Uchiha, throw it at them and run."
"Okay."
The next moment Itachi disappeared. He could have taken Sasuke with him but why would he need a third wheel....even though this Izumi isn't his girlfriend.
' This is getting more and more interesting.... '
