The ninth episode of Jujutsu Kaisen Season 2 has sent shockwaves through the anime community, after all, Gojo Satoru, the strongest, has been sealed!

Considering how Gojo had essentially guaranteed victory for the sorcerers just a few seconds ago, it came as a big shock for the fans when “Geto” appeared and sealed Gojo.

So, what happened? And, why?

How Was Gojo Satoru Sealed?

To seal Gojo, Pseudo-Geto used the Prison Realm. Prison Realm, also known as Gokumonkyo, is a special-grade cursed object containing a barrier that can seal absolutely anything and anyone in a pocket dimension.


It is the final remains of the Buddhist monk Genshin, and in its unused form, it resembles a cube small enough to fit in one’s hand.

To seal anything, one needs to place the object in front of the target and chant “Gate Open”.

Then the Prison Realm opens, and after one minute passes inside the target’s mind, they are captured.

After the user chants “Gate Close,” the object closes back to its previous form, and the victim is now sealed for eternity.

To ensure that Gojo Satoru would be caught off guard, Psuedo-Geto used the same tactic as Toji; He drove Gojo into a corner by overwhelming him using four Special-Grade Curses Spirits (Jogo, Hanami, Mahito, and Choso), while mixing humans with nearly a thousand transfigured humans.

This forced Gojo to use the 0.2-second Domain Expansion, and kill all thousand transfigured humans in 299 seconds.

However, this would only give him enough time to open the Prison Realm. To seal Gojo, one minute must pass in Gojo’s mind. To do that, a mysterious being used Geto’s body as a distraction.

When Gojo saw Geto again, all the memories from his “blue spring” of life came back flooding, as he saw a whole year pass by.

This was enough for the Prison Realm to seal the strongest, Gojo Satoru
