The world of Jujutsu Kaisen has expanded with a surprising new sequel, Jujutsu Kaisen Modulo, launching a new era set 68 years after the original story’s conclusion. With a brand-new cast of characters taking the lead, fans are asking one major question: what happened to the original hero, Yuji Itadori? His notable absence has sparked a compelling theory across social media—that Yuji is not just alive but may have become immortal.
A New Era for Jujutsu Kaisen
Jujutsu Kaisen Modulo began serialization in Weekly Shonen Jump on September 8, 2025. It is planned as a mini-series, expected to run for about six months and conclude in three volumes. The story introduces new main characters, Yuki Okkotsu and Tsurugi Okkotsu, and introduces a sci-fi twist to the jujutsu world with the arrival of alien invaders known as the Simurians. The first chapter was a 54-page, full-color feature on the cover of the magazine, showing the publisher’s strong confidence in the project. This new setting has been praised by fans for its daring shift in scope, allowing creator Gege Akutami to explore fresh ideas.
With the story jumping decades into the future and focusing on a new generation, the sequel functions more as a generational reboot than a direct continuation. The legendary sorcerers of the past are now spoken of as historical figures, and Yuji Itadori has been referenced as a legend from a bygone era, leaving his ultimate fate a mystery.
The Immortality Theory Gains Traction
The central theory among fans is that Yuji Itadori has survived into the new era, potentially ageless due to his unique history. This idea is fueled by two key aspects of his past established in the original series.
A Body Altered by Kenjaku
Yuji’s very origin is shrouded in experimentation. It was revealed that his mother’s body was possessed by the ancient sorcerer Kenjaku, who orchestrated Yuji’s birth for the specific purpose of creating a perfect vessel for Sukuna. This involved unnatural tampering, and many believe these experiments granted Yuji enhanced physical traits that could include an extended lifespan. As one fan on Reddit pointed out, “If he’s still alive, he probably hasn’t aged after all of the time he spent with Sukuna or Kenjaku’s experiments with his birth.”
The Lingering Effects of Hosting Sukuna
For a significant part of the original series, Yuji’s body was the vessel for the King of Curses, Ryomen Sukuna. Containing such a powerful cursed object for an extended period has undoubtedly left a permanent mark on him. Fans speculate that the immense cursed energy he housed and the supernatural nature of his existence as a vessel could have fundamentally altered his biology, slowing or even halting his aging process. This theory is bolstered by the fact that Sukuna himself existed for over a thousand years as a cursed object.
Fan Reactions to a Potential Return
The fanbase is deeply divided on whether they want to see Yuji return. While many are curious about his fate, a strong segment of the audience hopes he remains absent, not out of dislike, but out of a desire to see the character finally find peace.
Many fans feel that Yuji suffered immensely throughout the original Jujutsu Kaisen story. He was forced to carry the burden of Sukuna, witnessed the deaths of numerous friends and mentors, and saw his own body used as a weapon of mass destruction. For these fans, his story has been one of relentless pain.
“I don’t want Yuji to show up in Modulo. He has suffered enough in the original series.”
This sentiment is widely shared online, with many expressing that Yuji has earned a peaceful rest, away from the endless battles and curses that defined his life. They worry that his return would only mean more suffering for a character who has already endured too much.
The Door is Still Open for a Legend’s Return
Despite the compelling reasons for his absence, the narrative possibility for Yuji’s return remains wide open. Gege Akutami has deliberately kept his fate ambiguous. His unique lineage and the supernatural causes behind his potential immortality provide a perfect narrative excuse to bring him back if the story demands it.
If he were to appear, speculation suggests he could take on a role similar to his teacher, Satoru Gojo, acting as a powerful mentor for the new generation of sorcerers, Yuki and Tsurugi Okkotsu. Alternatively, he could be living in secret, emerging only when the threat becomes so great that the new sorcerers cannot handle it alone, perhaps as a final defense against the Simurian King.
For now, Yuji Itadori’s story in Jujutsu Kaisen Modulo is one of potential and mystery. Whether he appears as an immortal mentor or remains a legend of the past, his presence is deeply felt in the fandom’s discussions and theories.
