For Gojo enthusiasts, the prospect of his return through these means elicits not happiness but rather a sense of gloom.
In the universe of Jujutsu Kaisen, Kenjaku shares a link with Sukuna. However, fans eagerly await the clash between these two characters, regardless of potential alliances.

Ultimately, the King of Curses is not known for his loyalty or predictability; he acts on personal whim. So the idea of Sukuna potentially betraying Kenjaku after removing obstacles along his path not only sounds logical but also resonates with many.
While Sukuna is dubbed the 'King of Curses,' he possesses incredibly unique power and strength. Kenjaku, on the other hand, is a cunning and intelligent antagonist, an entity that has survived through the ages with an extended lifespan of over a thousand years.

Through the art of Shibuya Incident, Kenjaku can exchange bodies with others, even those who have passed away, through brain transplantation. The transplanted body will bear a long scar on the head (the skull opening scar). Afterward, Kenjaku can utilize both the physical strength and techniques of the body he inhabits. In other words, if Kenjaku transfers his consciousness into the body of a powerful sorcerer, he becomes an even more formidable threat.

Now, let's consider what happens if Kenjaku manages to seize Gojo's power. The showdown with Sukuna would escalate to unimaginable heights. Although Gojo failed in the battle against Sukuna, Kenjaku's learning and adaptability could turn the tables.
Kenjaku holds the advantage in knowledge, something Gojo lacks in the final battle. So, despite Sukuna's unmatched strength, facing Kenjaku in Gojo's body won't be easy.
For fans of Gojo, the prospect of his return through such means brings not joy but darkness. Gojo becoming a puppet in Kenjaku's hands adds another layer of pain for fans.
However, it cannot be denied that this is a shrewd move for a strategist like Kenjaku. If he indeed pursues this path, the conflict against Sukuna will be exponentially more dramatic. Gojo will be at the center of the battle, whether we like it or not.
