Simultaneous Transmigration: We Share a Role-Playing System

Dreaming about himself isn't really a nightmare, but for Itajō, the dream was strange and even frightening.

In the final moments of the dream, the other person's gaze held many things he couldn't explain: pity, sadness, hatred, and expectation.

Although Itari is usually carefree, in situations like this, his amazing intuition allows him to sense things that are difficult for ordinary people to notice.

And now, his intuition tells him that for a fleeting moment, the other person was thinking about something.

"If you were to die now, it might be a good thing."

Thinking of this, Itachi felt a cold sweat instantly soak through his back, and his breathing became rapid.

Moonlight streamed through the window, illuminating Itachi's face. Sweat beaded on his forehead, trickling down his cheeks and onto the blanket, bringing him back to his senses from the shock.

Yuujin Itadori looked out the window at the moon, recalling everything that had just happened, and with an expression of disbelief, he said in a daze:

"What the hell... is going on?!"

——————————————————————————————————————————————

Sixty-eight years later, in the cabin atop the mothership Naunax of the alien refugees Rumer, Yuujin Itadori and the Rumer boy Maru stood together before Karian, a Rumer creature resembling a cursed spirit.

Looking at the alien creature in front of him that was related to curse power, Yuuji Itadori found it hard to believe that the creature actually had a lifespan of two thousand years, but discussing such things now was pointless.

Because the entire region, and even the entire universe, will face annihilation.

After a period of reflection lasting sixty-eight years, Yuujin Itadori recently traveled to the moon with warriors of the Desquint tribe and Yuuka Otoko, the current leader of the Shadow Ninja, to challenge Gilbaris, a construct life form referred to as the Black Dragon by Keiryu Nishikita.

As for the ending, Maru didn't know; all they knew was that in the end, only Hisahito Itadori returned alive from the moon.

No one wanted to ask Hisahito Itadori what had happened. They all knew it was all meaningless. In any case, it would take Gilbaris at least several hundred years to fully recover and begin cleaning up the entire universe. So what did it have to do with them?

As for Itadori Hisahito, he was to blame for all of this. If it weren't for him, Nishikinda Keiryu would not have been able to defeat the opponent that Nishikinda Keiryu had already defeated.

Now, sixty-eight years have passed. Although Gilbaris has only recovered to 12.8%, it is still not an opponent they can defeat. Having lost Dabra and Yigu Yuhua, Itadori knows very well that he has lost his only chance to win back his brother Locke.

He may never be able to save Locke, who is trapped in the core of Gilbaris, and the entire universe will face the true end after Gilbaris is fully repaired.

Just when he was desperately trying to end his life alone, the young Maru, a boy named Rumel, offered him a completely new solution.

Using his techniques, he can create chaos in time and reverse the future.

"Is it really possible, Maru? Can your technique really achieve this?"

"If we set a life-or-death constraint, we can definitely do it, but I don't know how far we can go. I'm not sure how much information we can send back, but this is the only way we can."

"...I'm sorry, but in the end, there's nothing I can do. It's too powerful. Without Brother Locke and Teacher Gojo, Earth, the Milky Way, and even the entire universe would be in crisis."

"It's alright, Mr. Itadori. That's no longer an opponent that a normal living being could defeat. Neither Mr. Itadori nor Dabra could defeat that guy. That's probably why he chose to erase the traces of his own existence to destroy it. If it weren't for that damned demon Onijuro, if it weren't for that book, Taihei Fudoki, perhaps everything would be different."

"If, and I mean if, I were to let go of all constraints, could I leave as much information about the future as possible in the past, in the past version of myself?"

"I'm sorry, Mr. Itadori, I really don't know. Reversing time is a use I've never thought of before, and I'm not sure to what extent I can do it. I can only do my best. This is something we have to risk our lives to do. Without this awareness, all that awaits us is failure."

Yuji Itadori looked up and met the other's serious eyes, only then realizing what was happening.

It turns out they were the same kind of people; both had long since lost everything, having been stripped of everything by fate.

His innate kindness still compelled him to speak up and offer a reminder.

"Maru, you are different from me. You still have time, you still have a future, you are still young enough."

Before Haddō could finish speaking, Maru interrupted him directly.

"I know, Mr. Itadori, but this is my own choice. As long as it can change all of this, as long as everyone can have their own place to live and live a peaceful life... I feel that's enough."

The moment their eyes met, they both saw in each other's eyes a resolute determination to give up everything in order to turn things around.

Seeing this, Huzhang completely gave up on trying to persuade the other party, his mind filled only with his youthful dreams and his grandfather's last wish.

He wanted everyone to experience the right death; he wanted to die rightly surrounded by people.

"Then let's begin, Maru, let's turn this around."

Maru nodded as the other person offered him a hand, shook it, and began to activate his spell.

"Come on, Mr. Itadori, let's... change the past and reverse the future together!"

Back to this moment, inside the Palace of the Hungsing Star.

Tianyuan was using the nationwide barrier to search for Lu Suo's whereabouts, but for some reason, an ominous premonition lingered, causing her to subconsciously look around.

Just as she severed her connection with the barrier and stood up, a small black dot suddenly appeared beside her. The next moment, violent magical power surged into a vortex, sweeping over with an all-consuming pressure.

Before Tianyuan could react, a hand emerged from the vortex. Immediately afterward, a gaunt old man with three eyes struggled to squeeze half his body out of the vortex of magical power. The moment he saw Tianyuan, his eyes flashed with light, and he cried out in a hoarse voice:

"Don't look for the 'Taiping Fengtu Ji'! The real 'Taiping Fengtu Ji' was destroyed by yourselves long ago! Beware of the demon Onijuro! Never let the Black Dragon reappear in the world!"

But when he saw Tianyuan looking at him with a face full of astonishment, he was instantly overwhelmed by despair and screamed incoherently:

"Damn it... Am I too early? But this is the last time, I... I don't have time left! Please, please don't forget, please don't—"

Before he could finish speaking, the vortex of cursed power vanished from Tianyuan's sight without a trace.

Realizing what had happened, Tianyuan only had time to use a barrier technique to inscribe the words "Records of Peaceful Customs" on this body before he completely forgot everything due to the world's correction.

"Strange, what just happened? Is my memory failing me again?"
