Simultaneous Transmigration: We Share a Role-Playing System

"Master, such a precious item is only used to seal away a clone?"

The timid, hunched-over demon, cautiously questioned the devilish Onijuro, who, unusually, answered his question:

"I don't care about the people who can be sealed with this thing, and I can't seal the people who are worth my attention. It's just right to use it to seal Jin Tianjinglong's clone and buy us some time."

After saying that, the demon Onijuro used his telekinesis to bring the unconscious Itajiro out of the car, took out ten of Sukuna's fingers from his pocket, and fed them to him one by one.

The next second, the curse mark belonging to Ryomen Sukuna appeared on Itadori Yuujin's face. Ryomen Sukuna turned around and looked at the demon lord Kijuro, but did not make a move.

"You look pretty strong."

"Sukuna Oni, I didn't expect you to be so much more rational after losing your demonic body. I have a deal, would you like to hear it?"

"This way of addressing me...it seems we know each other before, right?"

"You seem to have gotten quite smarter."

"Stop wasting your time. Just say what you have to say. You've gone to such lengths to find all these fingers of mine, so tell me why I should help you?"

"Because I can help you defeat Nishikida Keiryu and avenge your previous defeat."

Upon hearing the name Nishikida Keiryu, Ryomen Sukuna instantly revealed an incredibly terrifying smile and questioned:

"You better not lie to me, or I'll make you regret it."

The demon Onijuro didn't speak. He pulled a physical body out of the eyeball in his hand. Sukuna recognized it at a glance as the body that had been sealed away a thousand years ago.

Sure enough, there was a large hole in his chest; his heart was gone.

"Your body has remained incorrupt for a thousand years, and those foolish lowly people actually worship you as an incarnation of Buddha. It's a pity they don't know that your ghostly body has real value."

"A demonic body? You mean that gigantic body? So it really wasn't a dream?"

"Of course, we've just been fooled, so... how about we cooperate to reclaim everything that truly belongs to us?"

Faced with the demon Onijuro's question, Sukuna pondered for a moment before decisively agreeing. Onijuro then used some kind of magic to restore Sukuna's body to its former vitality and broke off Itadori Yuujin's left little finger, feeding it to his own body.

Having regained his original body, Sukuna looked at his four arms, which now only had twelve fingers, glanced at Itajimaru, and then left with the demon Onijuro without looking back.

Before leaving, the demon Onijuro entrusted the prison gate to the real man and gave him the following instructions:

"Make sure it's clean. You can do whatever you want with it, consider it a reward for your good behavior today. Also, come home on time."

"Yes, Master!"

The prostrate man didn't dare to get up until the other person was completely far away. He looked at Itadori Yuujin on the ground with a cruel and mocking smile.

"Hehe! Hehehe! Hehehehehe!"

Meanwhile, in Hisahito Itadori's inner world, he opens his eyes and gets up, finding himself sitting on a train that has been submerged by seawater and is filled with marine life.

"You're awake."

An old but powerful voice came from ahead. When Huzhang looked up, he was so startled that he jumped up on the spot.

"Don't be so nervous, sit down."

Yuji Itadori, from 68 years in the future, looks at his younger self, his previous resentment replaced by heartache and relief.

"you……"

"Don't make wild guesses. I am you from 68 years in the future. I came to find you to tell you a story."

Having said that, before his younger self could react, Hisahito Itadori began to tell the story on his own:

"Many years ago, a person appeared in this world. He was blessed with a gift from heaven and a cursed future. Luck and misfortune befell him at the same time, making him destined to have the power to gain everything, and also to have a life with nothing."

"This divine favor became his eternal nightmare. To fulfill his mission, he had to reincarnate countless times, becoming a tool to solve disasters and appearing as a savior in people's hearts in different forms."

"Until one day, he transformed into a ronin of the Heian period, born into an era full of demons, monsters, and sorcerers. He knew his mission early on and began to slay demons and monsters and walk the righteous path."

"He is very strong, incredibly strong, not even human, but a god walking among the earth. He is also very weak, too weak to protect the people he loves, because that white fox is the object he is destined to eliminate, a cursed spirit."

Upon hearing this, Itachi's mouth gaped open, speechless, but the other party offered no explanation and continued:

"After leaving his lover, he continued to travel the world, aiming to defeat the country's strongest sorcerer, the demon Onijuro who wreaked havoc on the world, and finally accomplished this goal with ease."

"But the story doesn't end there. After defeating the demon Onijuro, he had basically exterminated and sealed away all the demons in the world with names and surnames. So the ronin went into seclusion for more than ten years and wrote his story into a biography called 'Taiping Fudoki'. In it, there is a sorcerer who was born during these years."

"The cursed king who transforms into a demon in human form, Ryoumen Sukuna."

Upon hearing this, Itadori Yuuji immediately realized that the other person was actually talking about Locke's past life, the story of Nishikinda Keiryu.

But he didn't understand what this story had to do with the current situation, or with him sixty-eight years later.

As if sensing his confusion, the elderly Yuji Itadori answered:

"I think you might be confused as to why I'm telling you this, because decades later, at the end of the wanderer's life, he met the strongest enemy of his life."

"The Black Dragon King of the Alien World, the endpoint of artificial intelligence, the ultimate judge who seeks to annihilate all organic life: Gilbaris."

"?"

When Itajō heard this name, which clearly only existed in games and anime, his entire being instantly switched from the style of the Warring States period chivalrous legends to the style of a space epic drama.

"You don't think that humans are the only intelligent life form in the vast universe, do you? In the almost infinite universe, one multiplied by infinity is still infinity, and the Gilbaris are an enemy of civilization created by one of the infinite races."

"He is the ultimate weapon created for peace, for eternal peace. For him, it is necessary to eliminate all intelligent beings. Therefore, he destroyed most of the civilizations in the universe that had never encountered an adversary before."

Hearing his future self describe it this way, Yuji Itadori could feel the utter despair of that world, an invincible adversary, a world destined for destruction, a Damocles' sword hanging over all civilizations.

As a member of a young civilization that has just left his own planet, Hisahito Itadori feels a deep sense of despair for this future.

Suddenly, however, the elderly Yuuji Itadori's tone became incredibly fervent, and with guilt and wide eyes, he opened his arms and shouted to his younger self:

"Faced with this enemy of civilization, Nishimada Kyōryū, nearing the end of his life, stepped forward, standing shoulder to shoulder with the gods despite his mortal body, ultimately burning himself out to accomplish the impossible!"

"He—defeated Gilbaris!"
