Suguru Geto is not actually alive in the current Jujutsu Kaisen anime and manga timeline. The character seen after the events of Jujutsu Kaisen 0 is actually an ancient sorcerer named Kenjaku who has taken over Geto's body by implanting his brain into it. This explains why Geto appears alive despite his apparent death in the prequel movie
. Gojo Satoru did kill the original Geto after his defeat, as confirmed in the manga, but Kenjaku obtained Geto's body because it was not properly disposed of. Kenjaku is a powerful antagonist who has survived for over a thousand years by possessing various bodies. He uses Geto's body and cursed techniques, especially Geto's ability to manipulate cursed spirits, to further his own goals
. Kenjaku's ultimate plan involves merging all humans in Japan into a single entity using cursed energy, creating chaos to explore cursed energy's potential. This is distinct from Geto's original ideology, which was focused on eliminating non-sorcerers to create a world only for sorcerers
. In summary:
- The "Geto" seen post-Jujutsu Kaisen 0 is Kenjaku in Geto's body.
- The real Suguru Geto died after his battle in the prequel.
- Kenjaku uses Geto's body and techniques to pursue his own agenda
