Gojo Satoru is unsealed in the Jujutsu Kaisen manga when Hana Kurusu (the “Angel”) uses her cursed technique Jacob’s Ladder on the Prison Realm’s “back gate,” which breaks the seal and releases him in Chapter 221.

How Did Gojo Get Unsealed?

Gojo’s unsealing happens after a long setup involving the Prison Realm, special conditions, and the Angel’s unique ability to erase all forms of cursed technique. The key idea is that only Angel’s technique, which can “purify” or nullify cursed techniques, could forcibly open the Prison Realm that had trapped Gojo since Shibuya.

Quick Scoop

  • Gojo is freed in Chapter 221 of the manga.
  • Hana Kurusu (Angel) uses Jacob’s Ladder to target the Prison Realm’s back gate , shattering the seal.
  • Due to Kenjaku’s precautions, Gojo is actually released 8,000 meters under the ocean in the Japan Trench, not next to his allies.
  • Gojo instantly survives the pressure, returns to the surface, and goes straight to confront Kenjaku and Sukuna , rather than reuniting with his friends first.

In simple terms: they used Angel’s “anti-curse” nuke on the back of the Prison Realm, Kenjaku tried to dump Gojo at the bottom of the sea, and Gojo just walks it off.

Step‑by‑Step: The Unsealing Process

1. Setting up the Prison Realm

  • The Prison Realm is a special cursed object that can seal even someone as overwhelmingly strong as Gojo, once certain conditions are met (like trapping him in a small area for a set time).
  • During the Shibuya Incident, Kenjaku uses this artifact to seal Gojo, removing the strongest sorcerer from the board and making the Culling Game and his larger plan possible.

2. Finding a Way to Break It

  • After Shibuya, the remaining sorcerers learn that normal exorcism or brute force won’t open the Prison Realm.
  • They eventually discover Angel , a sorcerer whose cursed technique can erase any other technique, which theoretically includes the complex binding around the Prison Realm.

The logic: if everything about the Prison Realm is a cursed technique, then Angel’s ability can strip it away.

3. Angel’s Condition and Jacob’s Ladder

  • Hana Kurusu agrees to help unseal Gojo as repayment for being saved and as part of the plan to fight Sukuna and Kenjaku.
  • Angel’s technique Jacob’s Ladder is invoked on the back gate of the Prison Realm, which is specifically mentioned in the story as the point they target to break the seal.
  • When Hana activates Jacob’s Ladder , a purifying/light-type effect is used to “pry open” and erase the Prison Realm’s binding, effectively canceling the seal.

4. Kenjaku’s Ocean Trap

  • Kenjaku anticipated the possibility of Gojo being released and relocated the front gate of the Prison Realm to open at a point 8,000 meters below the Pacific Ocean’s surface in the Japan Trench.
  • His goal was:
    • The extreme water pressure might crush or at least delay Gojo.
    • If that failed, he could try to ambush Gojo before he reunites with other sorcerers.

So even after the seal is broken, Gojo’s exit point is effectively a death trap designed by Kenjaku.

5. Gojo Walks It Off

  • Despite being released at abyssal depth , Gojo appears completely unharmed, underscoring the absurd scale of his power.
  • After surfacing, he immediately goes after Kenjaku and runs into Sukuna in Megumi’s body, leading to a short clash and a decision to postpone their all‑out fight for about a month.

Why Only Angel Could Do It

From an in‑universe perspective, Angel’s ability is uniquely suited to undoing the Prison Realm. The artifact’s sealing power is a complex cursed technique, and ordinary sorcery or brute force cannot overwrite its absolute rules once the target is sealed.

By contrast, Angel’s Jacob’s Ladder functions like a hard counter to cursed techniques, making her the only explicit, confirmed method to reliably break Gojo’s seal without destroying him in the process.

How Fans Talk About It (Forum‑style View)

“We waited YEARS for manga Gojo to come back and Gege drops him in at 8,000m under the sea like it’s nothing.”

“The fact that Angel nukes the Prison Realm and Gojo just casually shows up to press Kenjaku and Sukuna is peak Gojo energy.”

Many fans also point out how the unsealing:

  • Pays off long‑term setup from the Shibuya Incident.
  • Immediately raises the stakes by putting Gojo face‑to‑face with both Kenjaku and Sukuna instead of giving him a slow reunion arc.

“Latest News” and Ongoing Discussion

Even in 2025–2026, the topic “how did Gojo get unsealed” is still trending in fan discussions, especially with anime‑only viewers catching up to the Prison Realm storyline. New explainers and videos break down the mechanics of the Prison Realm, Angel’s role, and the ocean trap, often revisiting Chapter 221 as one of the manga’s most anticipated moments.

TL;DR (Story Version)

Gojo was sealed in the Prison Realm during the Shibuya Incident, turning the tide in favor of Kenjaku’s grand plan. Much later, the sorcerers recruit Hana Kurusu , whose Angel technique, Jacob’s Ladder , can erase any cursed technique, including the Prison Realm’s bindings.

They perform a ritual targeting the back gate of the Prison Realm, and when Angel fires off Jacob’s Ladder, the seal finally breaks. But because Kenjaku moved the front gate to 8,000 meters below the sea , Gojo materializes in a deep‑sea trench instead of on land.

Being Gojo, he shrugs off the pressure, returns topside, and doesn’t even stop to say hello—he heads straight for Kenjaku and Sukuna, setting up one of the biggest showdowns in the series.
