In the recent chapter of Jujutsu Kaisen Modulo revealed some information was revealed that has caused the fandom to have some intense debates. It surrounds one decision taken by the Gojo Clan. They have forbidden to allow anyone to fully use the Ten Shadows Technique. This ability is seen as one of the strongest inherited techniques in the universe of Jujutsu Kaisen, which is why banning something like this felt counterintuitive.
While it is understandable to question a decision that would effectively stop a user from unleashing their full potential, it is important to take a deeper dive to understand the motive behind the action. If we were to take a look at the history, trauma, and political paranoia of the Gojo clan, the reasoning becomes disturbingly clear.

The main reason could be as simple as the ban is rooted in fear that came from the historical defeat. In Jujutsu Kaisen Modulo, there is a piece of information that has been reinforced. We are talking about the rivalry between Limitless + Six Eyes and the Ten Shadows Technique. Historically, clashes between these two techniques were not theoretical power-scaling debates because they ended in real deaths.
Most notably, a Ten Shadows user once defeated and killed a Gojo clan head who possessed both Limitless and Six Eyes. That single event permanently scarred the clan’s collective memory. For a lineage that prides itself on producing “absolute” sorcerers, the idea that another technique could reliably counter and even kill their strongest asset was unacceptable. Rather than viewing Ten Shadows as a tool to be mastered, the Gojo clan began seeing it as an existential threat.
Mahoraga: The untamable disaster

Among all Ten Shadows shikigami, Eight-Handled Sword Divergent Sila Divine General Mahoraga can only be described as a being that is a walking calamity. The way it can adapt to any situation would make the opponent push past their limits. It is literally an unstoppable force that could easily end up adjusting to opponents' technique and counterattack. We have seen that even Sukuna treated Mahoraga with extreme caution. That is why, for people of the Gojo Clan, Mahoraga is seen as the worst-case scenario.
It is a summon that even most Ten Shadow users cannot tame, control, or safely deploy. There would always be consequences. If a user fails the ritual or loses control mid-battle, Mahoraga doesn’t just kill enemies; it erases allies, infrastructure, and potentially the user themselves. In other words, Mahoraga doesn’t just threaten opponents; rather, its existence threatens the clan’s stability.
Yuka’s restriction in Jujutsu Kaisen Modulo

This philosophy directly impacts Yuka Okkotsu’s situation in Jujutsu Kaisen Modulo. Rather than being allowed to summon the full roster of shikigami, Yuka is restricted to limited applications of the technique, drawing out certain shikigami abilities without fully manifesting them. It is a deliberate nerf, but one designed to neutralize risk rather than potential. By doing this, the Gojo clan ensures that Ten Shadows never again becomes the weapon that turns on them.
Final thoughts
From a power-scaling perspective, fans are right to call the ban ridiculous. Combining Limitless and Ten Shadows under one clan could have cemented Gojo's dominance forever. But Jujutsu Kaisen Modulo makes it clear that clans don’t operate on optimal logic; they operate on fear, legacy, and survival. The Ten Shadows Technique didn’t just rival the Gojo clan. It traumatized them. And in the world of jujutsu, fear often dictates policy more than strength ever could.
