Jujutsu Kaisen: Why Was Gojo Sealed Instead Of Killed?

The Shibuya Incident was built to meet the exact rules needed to seal Gojo. Civilians trapped in the station forced Gojo to protect them, the Special Grades battered him nonstop to burn precious seconds, and the shock of seeing Suguru Geto’s face created the brief hesitation the Prison Realm needed.

Once Gojo stayed within range for that relative minute, the seal snapped shut. From that second on, everything that happens later, the Culling Game setup, colony rules, and Kenjaku’s larger plan, became possible because the one Sorcerer who could stop it in an afternoon was locked away.

How Was Gojo Sealed In Jujutsu Kaisen?

Gojo was sealed during the Shibuya Incident using the Cursed Object known as the Prison Realm, a living barrier that can trap anything if strict conditions are met. Multiple Special-Grade Curses pressured him nonstop to burn precious moments while the Prison Realm was brought within range.

At the key moment, the enemy revealed Suguru Geto’s body (now controlled by Kenjaku), which shocked Gojo just long enough for the Prison Realm’s condition to trigger, which was keeping the target within a close radius for a minute in their mind. Once that mental window opened, the object latched on, and the command to close sealed him inside.

After the seal took hold, Gojo’s Cursed Energy was cut off, and the cube processed him, becoming immovably heavy until stabilized. Kenjaku then escaped Shibuya with the Prison Realm in hand, removing the strongest Sorcerer from the battlefield in one move.

Sealing Him Was A Better Choice

Killing Gojo was the worst choice tactically and politically. Tactically, Limitless bends space, and his reactions are inhuman; a failed kill attempt would only awaken the most dangerous counterattack. Politically, a confirmed death would unify Jujutsu High, turn Gojo into a martyr, and harden every faction against Kenjaku and his team.

To make matters worse, eliminating this Six Eyes bearer might just restart the cycle with a new one down the line. Sealing Gojo dodged these outcomes since there was no body to bury, no funeral to rally around, and no immediate risk of a new Six Eyes awakening.

Keeping Gojo alive but sealed also created options. The villains could waste the time of Gojo's allies as they attempted to unseal him. In short, a corpse would have ended the scene while the seal controlled the tempo of the whole story.

How The Seal Enabled The Plan

Shibuya’s design matched the Prison Realm's conditions perfectly. Gojo had to be close, mentally pinned, and held for a perceived minute. The human shield of civilians fixed his focus. The Curses hammered him without pause, and Kenjaku’s use of Geto’s body delivered the only realistic mental freeze he would have never had.

That single stumble was enough to close the lid. With Gojo gone, the board changed overnight: Yuji, Megumi, Maki, Yuta, and others had to carry fights a level up, which opened lanes for the enemy to place colonies, revive old Sorcerers, and move the merger forward without a one-man raid flattening it.

The most important part was that sealing bought time. The Culling Game and merger were slow-burning schemes that needed days and weeks. A sealed Gojo guaranteed that window because he couldn’t blast his way out, and freeing him would require rare methods and perfect timing. That delay was the win condition for Kenjaku.
