The Unique Power of Gojo in Jujutsu Kaisen
First and foremost, it is important to acknowledge that Gojo’s rarity in Jujutsu Kaisen is due to the existence of the Six Eyes. The two individuals who possess the Six Eyes cannot coexist at the same time. Currently, the only known holders of the Six Eyes are Satoru Gojo and the legendary Gojo Head from the Edo period (or Keicho).
In chapter 145, Tengen explains that a few generations ago, there was a Star Plasma Vessel and a holder of the Six Eyes born into the Gojo clan.

Gojo and Riko: A New Generation
In this era, we have Gojo and Riko, who were born two years apart. Gojo is the first wielder of the Six Eyes born after approximately a century. However, wielders of the Six Eyes always have a fateful connection with Tengen and the Star Plasma Vessel.
In the story, Gojo is tasked with protecting Riko and ensuring the success of the union between her and Master Tengen. Unfortunately, the transfer did not happen as Tengen had hoped.
Now, following Gojo’s departure, even if there is another sorcerer with unique traits similar to Gojo’s, they will emerge at least after several decades or even centuries.
Although we wish to delve deeper into this matter, it remains quite difficult. There is not much information about the Gojo clan, as the storyline has not introduced any other members apart from Satoru Gojo. Yuta is merely a distant relative, so he cannot be considered part of the direct lineage with this clan.
