Konoha Village, training ground near the Ninja Academy.
On a bench against the railing, a boy wearing goggles, about 4 or 5 years old, opened his eyes.
Just moments ago, an extra set of memories appeared in his brain.
His original memories told him his name is Uchiha Obito, he is five years old this year, a student in Class 1-A of the Ninja Academy. Because he ranked last in every assessment for the past six months since enrollment, he became the dead last of the class.
His dream is to become Hokage. He often helps old ladies cross the street. The person he likes the most is Nohara Rin, who grew up with him as childhood friends.
But, the extra memories told him.
He, Uchiha Obito!
The great schemer of the ninja world, infiltrated Konoha and launched the Nine-Tails Attack, causing the death of his sensei and his wife.
He led the Rinnegan user Nagato astray, developing the second generation of the Akatsuki organization.
He participated in the Uchiha Clan Massacre Night, slaughtering the entire Konoha Military Police Force.
He secretly collected the Tailed Beasts, started the Fourth Great Ninja War, became the second Six Paths Sage, and fought against the entire world by himself.
Finally, he repented, blocked an attack for the Child of Prophecy, the reincarnation of Asura, the child of his sensei Namikaze Minato, Uzumaki Naruto, and died.
For a long time, his dream was to cast the Infinite Tsukuyomi to create a world with Rin. He often hid in the shadows to stir up trouble. The person he liked was Rin, who was killed by Kakashi himself...
The two sets of memories, except for the point of liking Rin which remained unchanged, were completely different in all other aspects. No, they were completely opposite.
For a moment, Obito fell into mental confusion. The two sets of memories constantly collided and merged, eventually forming a complete whole...
Uchiha Obito was reborn!
He somewhat incredulously raised his hands. What entered his view was a pair of somewhat tender small hands.
His gaze shifted from confusion to shock.
"I, actually reversed time and returned to the past?"
And also...
Sensing a strangely familiar power seemingly entrenched within his eyes, he subconsciously activated it.
Immediately... his eyes turned blood red, the black pupils differentiated into one tomoe, two, three...
Finally, the three tomoe spun continuously, transforming into a large pinwheel shape composed of three sickle blades.
This is... his dual Kamui Mangekyō Sharingan!
You must know, his body is only five years old this year. Awakening the Mangekyō at five years old? Even Uchiha Madara would be scared into unleashing his Complete Body — Susano'o upon hearing this.
He could no longer tell if it was because his spirit received a strong stimulus, leading to the re-awakening of these eyes, or if he had brought the eyes back from the future.
The next moment, he instinctively used the ability of his right eye.
Immediately, the space around him twisted, his entire person, as if erased chalk lines by a rubber eraser, abruptly disappearing from the real world...
Kamui dimension.
Obito's figure appeared here.
This world outlined in black and white was his final resting place.
"Indeed, the transfer speed of dual Kamui is much faster than with a single eye, almost without any delay. Even if it's not quite as fast as Sensei Minato's Flying Thunder God, it's close."
Obito couldn't help but sigh.
The Mangekyō Sharingan only reaches its maximum potential when a pair is gathered. In his previous life, he only had a single right eye for a long time. Although he eventually gathered both eyes, his condition wasn't good then, and he still had to face Kaguya Ōtsutsuki, the progenitor of chakra, so he didn't have much time to explore the abilities of both eyes.
Now was the perfect time to experiment.
But just as he was about to conduct more experiments, suddenly, a sharp pain came from his right eye.
A line of bloody tears had already flowed out uncontrollably.
Obito covered his eye: "I almost forgot, I don't have Hashirama's cells now, I can't offset the side effects of the Mangekyō Sharingan."
"And..."
He looked over his small, young body.
"I'm only five, still too young. Maintaining the Mangekyō for long periods is too taxing on the body. To avoid ending up weak and sickly like Itachi, it's best to use these eyes sparingly for now."
Thinking this, Obito deactivated the Sharingan state.
He felt lost.
He clearly met Rin after death, sank into slumber together with Rin, which counted as a pretty good ending. How did he suddenly return to the past?
What could he do now that he had returned to the past?
Wait...
He suddenly remembered, at this point in time, Rin, Sensei Minato, Big Sis Kushina are all still alive, Nagato hasn't turned to darkness, the Uchiha are still the largest clan in Konoha...
"Hahaha, hahahaha!"
Obito couldn't help but laugh wildly. He knew what he wanted to do now.
But as he laughed, his voice became hoarse, and tears streamed down.
He had no doubt that he possessed the ability to change the future. Not only did he know a massive amount of future information, but he also had the dual Kamui Mangekyō...
With just one eye he dared to run wild across the entire ninja world, let alone with two eyes? He didn't know how he could lose!
But precisely because of this, he felt a tremendous sense of absurdity.
After the Infinite Tsukuyomi plan completely collapsed, he recognized a fact.
He wasn't a savior, but a butcher.
He brought even more despair to this already scarred and battered ninja world.
The misfortune of Sensei Minato, Big Sis Kushina, Uzumaki Naruto's family, the corruption and fall of the Akatsuki, the hundreds of Uchiha lives, and the countless lives lost in the Fourth Great Ninja War... all were more or less related to him.
Everything started from him witnessing Rin's death and awakening the Mangekyō Sharingan in despair.
Damn my Kamui can't hide tears...
He was simply the number one bastard in the ninja world!
That's why he resolutely blocked the attack for Naruto. Even if it wasn't enough to repay the sins he carried, repaying a little was still something...
However, now, this bastard, could actually return to the past and personally atone for the crimes he committed. How ironic is that?
Good people get no reward, but bad guys can get redemption?
This world is too surreal. He didn't know if he was crazy, or if the deity who sent him back was crazy?
Why did he deserve such preferential treatment?
He wasn't worthy!
In this timeline, nothing has happened yet. No one has felt the pain Nagato spoke of.
Therefore, the values of Sensei Minato's teacher, Jiraiya, still hold true. People can achieve mutual understanding.
After all, good people are always naive and kind. Even if they knew what would happen in the future, as long as he was willing to repent and turn over a new leaf, most people would forgive him.
But he couldn't forgive himself...
Those hellish scenes he personally created were etched into his mind like carvings from a knife and axe, impossible to forget. Even returning to the past couldn't make him treat it all as if it never happened.
But...
A bastard returning to the past, no matter how hard he tries, he is still that bastard.
But a bastard returning to the past, if he does nothing, then he is worse than a bastard!
Even though he knew he wasn't worthy, he must do everything in his power to ensure Sensei Minato, Big Sis Kushina, and Uzumaki Naruto have a happy family; to make the Akatsuki organization truly the Dawn; to help the Uchiha avoid their fate of annihilation...
As for Rin, he will protect her personally. He will bring peace to the world, create a world where Rin can live happily!
