Present Time
Itachi looked at Izumi's grave and sighed in disappointment. If it had been the Itachi of this world who committed the massacre, then it would have been better. He could have gotten a pair of Mangekyo Sharingan from himself and also shown off against the most controversial character in Naruto.
The most depressing thing is that he can't do anything.... Danzo is already dead, and so are all the ANBU. Only Hiruzen remains alive among the culprits, but direct death is a mercy to him. Seeing his clan members die one by one, and by another Konoha shinobi, is much crueler than this direct relief.
"You both can come out now."
Finally, after making a small but beautiful grave for Izumi surrounded by mountains full of white lily flower fields and teleporting to a nearby mountain, Itachi spoke while looking into the void.
"Itachi, you still have the habit of meddling in other people's business, huh?"
The next moment, two young men, each around sixteen to seventeen years old, emerged standing on air.
"Sasuke?"
Seeing the one speaking, Itachi felt like he was hallucinating.... He was now seeing the adult version of Sasuke, but.... how was that possible?
"Heh, you still have good eyes."
Hearing Sasuke's confirmation, Itachi started guessing.
"Are you from the future? And you are..... Haruto?"
"Yo, Uncle Itachi!! I was just stopping this idiot from doing anything wrong."
"You are the idiot, baka. How is taking revenge for my clan something wrong?"
"It doesn't matter who takes the revenge. Anyway, I don't think you came here for only this matter, right?"
"Indeed. Itachi, before I defeat your future self, I want to defeat you first."
"Hmm? You are scared of my future self, so you want to settle the score with me?"
Itachi looked at Sasuke with disappointment.
"You bastard, who are you calling a coward?... I challenged that idiot many times, but he said that I have to defeat you first before I am qualified to fight him..... I will defeat you first, then I will beat that arrogant guy."
"Hmmm... okay. What about you, Haruto?"
"I just saw this idiot coming here, so I followed. Though, since two people are fighting, why not include me?"
"I do not need your help."
"How about you two fight me together?"
Hearing this, Haruto began to think about Itachi's proposal. He didn't dare underestimate Itachi, unlike Sasuke, who became overconfident the moment he awakened the Rinnegan.
"You bastard, how dare you underestimate me this much. I can defeat you even without this idiot's help."
Sasuke, feeling the underestimation, especially from a fourteen-year-old brat, opened his Mangekyo Sharingan in anger.
"I accept."
"I do not accept."
"Very well, since you two accept, then we can fight. Let's move to another space-time lest we destroy this precious land."
"Hey, I said I do not accept."
"Let's go, Haruto."
"Yes, Uncle Itachi."
With that, Itachi and Haruto ignored the stubborn Sasuke, and Haruto opened a portal to another time-space, followed by Itachi.
"I will definitely beat you two idiots until you cry."
Being left alone, Sasuke cursed one last time before ultimately following them.

Unknown Dimension
In a strange place with a purple sky and gray ground filled with craters and mountains stood three young men, each with different eyes.
"I, Uchiha Haruto, challenge Uchiha Itachi to this battle."
"I, Uchiha Sasuke, challenge Uchiha Itachi to this battle."
"Ahh.... I accept your challenge."
Itachi said while thinking of the Pokémon battles in the anime where the referee said this.
Fire Style: Great Fireball Jutsu
The next moment, Sasuke spat out a small meteor-sized red fireball toward Itachi.
Earth Style: Earth Flow Wall
Taijutsu: Thousand Meteor Fists
Itachi countered the huge fireball with a huge kilometer-wide and kilometer-long earth wall.
Immediately, the two collided, and while the fireball was extinguished, the earth wall became red-hot.
The next moment, Itachi took a deep breath and punched with his right hand toward the red-hot wall.
The earth wall shattered into pieces, which rushed toward Sasuke and Haruto like a red meteor shower.
One Sword Style: Polar Vortex
At the same time, Haruto, who had been watching the show, took out a pure white sword and, after taking a sword stance, swung it.
With a single swing, a huge gust of cold, frigid wind gushed out, freezing all the small meteors, which ultimately fell midway.
"Nice swordsmanship...."
Seeing Haruto easily counter his attack, Itachi praised him in appreciation.
Although this attack was still in the Super-Kage range, he couldn't have blocked it with pure swordsmanship.
"Very well, then try this...."
The next moment, Itachi stomped his right foot against the ground.
Electromagnetic Concrete Release: Infinite Citadel
(From now on it will be ECR.)
Almost simultaneously, with Itachi as the center, the area within a ten-kilometer radius started dividing into even squares.
Huge structures began rising from the ground, creating a grand city within a minute.
"Itachi, I will not play house-house with you."
Fire Style: Hephaestus Curse
In retaliation, Sasuke spat out a column of fire several kilometers wide toward the hundreds-of-stories-tall buildings.
One Sword Style: Thousand Ice Cuts
Haruto also swung his sword a thousand or so times within a few seconds, each slash hundreds of meters long, rushing toward the huge buildings ready to slice the city into pieces.
"It can't be that simple, can it?"
With Itachi's words, the sea of fire and sword slashes collided with the buildings, but before they could touch them, blue barriers prevented them from moving further.
A few seconds later, when everything calmed down, the city was the same as before.
ECR: Ten Million Cannons
Simultaneously, all the windows opened as cannon barrels emerged from them.
Subsequently, all of them fired thick blue rays that targeted the two Uchiha from all directions.
Susanoo Final Stage : Indra's Descent
One Sword Style: Lightning Demon Barrier
Facing the millions of rays, Sasuke directly opened his hundred-meter-tall condensed Complete Susanoo as a defense.
Haruto, on the other hand, plunged his sword into the ground while inserting lightning chakra into it, forming a barrier around himself and preventing the blue rays from entering.
"Then, how about this?"
ECR: Attraction
The next moment, two two-hundred-meter-tall buildings on the two sides of Susanoo suddenly moved toward each other at speeds exceeding the speed of sound.
By the time Sasuke reacted, his Susanoo was already being crushed between them.
Haruto, who was facing the same situation, used lightning chakra to increase his speed, thus escaping the disaster.
But this was only the beginning, as thousands of buildings started moving irregularly throughout the city at bullet-like speeds.
Susanoo was already trapped within tens of buildings, making it look like the center of a Rubik's Cube that was rotating and changing patterns every second.
Rinnegan: Super Shinra Tensei
The next moment, fed up with pushing away the buildings, Sasuke opened his Six-Tomoe Rinnegan.
A huge repulsive force pushed everything away from him.
Although none of the buildings were broken, the nearby one-kilometer area around him became barren.
Seeing Sasuke free of trouble, Itachi rushed toward him and punched toward the Susanoo's head.
Seeing this, Sasuke swung his hundred-meter-long sword, but the next moment Itachi was replaced by a thousand-meter-tall building.
"Fuck you."
Seeing Itachi's disgusting tactics, Sasuke immediately used Amenotejikara to switch places with Itachi.
Seeing a thousand-meter-tall building crashing toward him, Itachi immediately used Flying Thunder God to teleport away.
Amenotejikara
Flying Thunder God
Amenotejikara
Flying Thunder God
In the next second, Itachi and Sasuke played this teleportation game dozens of times before Itachi finally teleported the flying building away, preventing himself from being crushed by only a few centimeters.
"Sasuke, Haruto, let's level up."
Ryōiki Tenkai: Hakua Kyūden
Domain Expansion: White House
Indra's Arrow
One Sword Style: Hell Demon Valley
Seeing Itachi about to open his Domain Expansion, Sasuke and Haruto immediately attacked.
"It's too late."
Conversion: Explode
The next moment, the kilometer-long Indra's Arrow made of purple lightning and the red-black slash exploded midway.
With the help of the Conversion property, Itachi simply destabilized the attacks, causing them to explode midway.
