One-Punch Man World.
"Ah, are these two Uchiha Itachi and Uchiha Sasuke?"
Saitama looked at the two names, scratched his head, and said curiously, "I feel like I've heard these names somewhere before."
Saitama was still living in his own home. After being exposed by the video, although he became known to the S-Class Heroes and A-Class Heroes of the Hero Association,
The Hero Association still hadn't promoted him to an S-Class Hero.
It was said that within the Hero Association, a meeting was held for Saitama. The discussion was roughly about whether to immediately promote Saitama to S-Class or let him continue living a quiet life.
They discussed back and forth, but none of the various proposals could pass.
This led to a very awkward situation within the Hero Association. If they had promoted Saitama to S-Class from the start, there wouldn't have been so much trouble.
But now, if they suddenly promoted Saitama to S-Class, how would they explain it to the public?
Could they say Saitama is a super powerhouse who, in a video, took down an alien that could be rated as 'God-level'?
Then the public would surely ask, what video?
One must know that only special personnel can have the multiverse projection; others basically aren't qualified.
A small number of people knew of Saitama's existence, but the vast majority had no idea who Saitama was.
In the end, the Hero Association chose to ask for Saitama's opinion. Saitama felt it was strange and stated that maintaining the status quo was fine. If possible, he'd like them to get rid of the 'neighbor' next door.
And he wanted the other S-Class Heroes to stop visiting him all the time. Those S-Class Heroes would come over and want to spar with him as soon as they arrived, which was really boring.
Ultimately, the Hero Association could only respect Saitama's choice and let him continue being a B-Class Hero.
"These two names... they're a bit familiar." Genos also frowned slightly. Too many things had happened lately, and he had subconsciously forgotten some things.
Most recent events revolved around Saitama-sensei. Having been busy for so long, Genos had almost forgotten who Sasuke and Itachi were.
"That Sasuke was the No. 1 in the previous video. He also appeared in the comment section, the guy who asked this fellow about his training method."
At this point, Tatsumaki quietly entered. She didn't use the front door but flew in through the balcony.
"Enter through the front door!" Saitama complained. He felt these S-Class Heroes were all very strange—not using the front door and insisting on entering from weird places.
With Tatsumaki's reminder, Genos had an epiphany. "So it's him. No wonder he looked familiar."
"But it's strange. Since they're brothers, why are they fighting?"
Saitama expressed his confusion. At this time, he also remembered that Sasuke had once said
that to kill Itachi, he was willing to pay any price to obtain Saitama's method of becoming strong.
Later, Saitama said he didn't need Sasuke to pay anything; as long as the other party had perseverance, they could become strong. He even publicly shared his training method once.
Although many people sent him private messages saying Saitama was a liar and that if he wasn't willing to give it, he shouldn't say anything!
Another group of people asked Saitama what happened in between.
Some even asked what important thing Saitama lost while becoming strong.
Saitama answered them one by one. Anyway, staying at home with nothing to do, chatting with them wasn't bad.
The most serious among them was naturally the one named Sasuke.
So Saitama had a deep impression of him. Because of this, he was also curious why the two brothers had ended up like this.
"It's probably the older brother's fault."
Tatsumaki spoke. Looking at Uchiha Itachi and the young Sasuke in the video, she said calmly, "He's probably like me, thinking that a younger sibling only ever needs to accept their protection and shouldn't consider anything else."
"Eh? Your sister?" Saitama looked at Tatsumaki in surprise. This was probably the first time he had heard Tatsumaki talk about her sister.
"Yes, my sister. I'm aware of the things she's doing now." Tatsumaki looked at Saitama with a mysterious smile and said, "If it weren't for that video, you'd probably be fighting my sister right now."
"?"
Saitama tilted his head, looking completely puzzled as to why he would have to fight Tatsumaki's sister.
The video continued playing.
The memories of young Sasuke and Itachi continued, showing their beautiful childhood life.
However, after a while, the scene changed abruptly. On a 'blood-colored' night, Uchiha Itachi held a katana and stood atop a utility pole, a 'blood-colored' moon behind him.
But what drew even more attention was that the Three-Tomoe Sharingan in Uchiha Itachi's eyes had changed into another form.
This was the Mangekyo Sharingan.
Accompanied by screams and blood, the Night of the Clan Massacre began. These were memory fragments from the past.
At this moment, Uchiha Itachi was like a cold and heartless executioner, killing all his clansmen.
In the end, only Uchiha Sasuke and Uchiha Itachi remained of the entire Uchiha clan.
The young Sasuke sensed something was wrong and immediately ran home, only to see the corpses of his parents and his own older brother standing there.
Facing this tragic scene, Uchiha Sasuke, still unaware of the situation, asked Uchiha Itachi who could have done such a cruel thing.
Finally, Uchiha Itachi used the genjutsu of his Mangekyo Sharingan on Uchiha Sasuke, forcing him to see what had happened.
This was the sequence of events of the massacre night, which caused Uchiha Sasuke to let out a terrified cry, as if he couldn't accept this reality.
Uchiha Sasuke asked Uchiha Itachi why he did such a cruel thing.
Uchiha Itachi replied that he wanted to measure his own capacity. As for why he didn't kill Sasuke,
He wouldn't answer that question now. Not until Sasuke obtained the same eyes as him.
Only then would Uchiha Itachi tell him the answer.
As he spoke, Uchiha Itachi displayed the Mangekyo Sharingan again. This pair of eyes would henceforth become Sasuke's nightmare.
The once gentle brother had vanished, replaced by an Uchiha Itachi who slaughtered his entire clan and killed his parents.
As for Sasuke, he transformed from an innocent youth into an avenger. He wanted to kill Uchiha Itachi!
Finally, the memories in the video ended.
A short sequence of memories had clearly explained the relationship between Uchiha Itachi and Uchiha Sasuke.
Inside a room, Uchiha Itachi rested with his eyes closed.
The grown-up Sasuke stepped into the room, his Three-Tomoe Sharingan staring at Uchiha Itachi.
Uchiha Itachi also slowly opened his eyes, the Three-Tomoe Sharingan rotating slowly within.
The two looked at each other, their Three-Tomoe Sharingan reflecting the other's figure.
The battle between brothers was about to begin.
