Is Yuji Itadori the Reincarnation of a Forgotten Sorcerer?
The Jujutsu Kaisen fandom has been a hotbed of speculation, especially with the intense events of the Shibuya Incident and the Culling Game arcs. While the manga has confirmed that Kenjaku, the ancient sorcerer inhabiting Suguru Geto's body, is Yuji's mother, a compelling new fan theory suggests this is only half the story. The theory posits that Yuji's father was not a random human, but the reincarnated soul of a powerful, forgotten sorcerer from the Heian era—one whose very existence was erased from history.
The evidence, according to fans, lies in Yuji's bizarre physical capabilities. His superhuman strength, speed, and durability before ever consuming a Sukuna finger are anomalies that simple "physical prowess" can't fully explain. The theory argues that Kenjaku, in its centuries-long plan, wouldn't have chosen a random vessel. It needed a body with a unique constitution, one capable of not only containing Sukuna but also potentially overpowering him.
This forgotten sorcerer, the theory suggests, was a contemporary and rival to Sukuna, perhaps possessing a technique that could directly counter the King of Curses' "Cleave" and "Dismantle." Kenjaku, ever the puppet master, orchestrated the reincarnation of this rival's soul into the Itadori bloodline, waiting for the perfect moment to combine it with its own cursed lineage. This would make Yuji not just a vessel, but a living, breathing counter-measure to Sukuna, created by his own mother. It reframes Yuji's entire journey from a boy who accidentally stumbled into the world of jujutsu to a living weapon forged for a specific, terrifying purpose. This theory gives a deeper meaning to Yuji's inherent ability to resist Sukuna's influence and his unnatural aptitude for learning complex curse techniques, suggesting he's tapping into a latent power from a past life.
