Gojo Satoru's True Motives:

One theory suggests that Gojo Satoru, one of the most powerful characters in the series, has secret motives that have not been revealed yet. Some fans speculate that Gojo might have a hidden agenda related to the history of curse energy and the curse world. The idea is that Gojo knows more about the background of the Jujutsu battle than he discloses, and his goals may be more complex than they initially appear.

Suguru Geto's Return:

Suguru Geto, a former friend of Satoru Gojo, is introduced as an antagonist in the series. One theory proposes that Geto might potentially return to the side of the protagonists in the future. This could be based on a deep connection between him and Gojo, and there is speculation that there is more to Geto's backstory than what has been shown so far. Some fans believe that his motivations could be more intricate, and there might be a twist involving his return to the side of the protagonists.

Satoru Gojo's True Name:

A more speculative theory revolves around Gojo Satoru's alleged true name. In the series, it is mentioned several times that Gojo keeps his full name a secret and only reveals it to a few trusted individuals. Some fans speculate that his real name could play a significant role in the plot and may have a connection to ancient curses or legends. This theory is based on the concept that names in the world of "Jujutsu Kaisen" could have deeper meanings and power.
