Chapter 221 of Jujutsu Kaisen delivers one of the most anticipated moments in the series—the unsealing of Satoru Gojo. What follows is not only the reintroduction of the most powerful sorcerer in the modern world but a significant escalation in the narrative stakes.
From philosophical discussions about time to explosive face-offs, this chapter is dense with meaning, emotion, and foreshadowing.
Let’s unpack the key moments and characters that define this critical chapter.
Unpacking the Prison Realm: Gojo’s Imprisonment and Release
The chapter opens with a discussion about the Prison Realm. We learn that physical time doesn’t flow within it. This means that for Gojo, who has been trapped since the Shibuya Incident, time could feel like nothing—or like an endless abyss. It’s stated that only 19 days have passed in the outside world, but the psychological toll on Gojo could be far greater depending on his perception.
The technical explanation of the Prison Realm serves more than just plot exposition. It raises existential questions: what happens to the psyche when deprived of time? Could even Gojo, with his immense power and intellect, remain the same after such isolation?
Characters involved in this part:
- Kinji Hakari: He plays the rational observer, explaining the temporal mechanics of the Prison Realm. His pragmatic tone balances the emotional weight of Gojo’s imprisonment.
- Shoko Ieiri and Ieri’s assistant: Both assist with the sealing box and its protection.

Angel and Hana: The Key to Freedom
To unseal the Prison Realm, the group relies on Angel and her cursed technique. Hana, Angel’s host, is visibly tense—clearly aware of the gravity of freeing someone like Gojo. The chapter treats this scene with reverence. When the incantation is invoked, the cube disappears.
But Gojo isn’t immediately visible. Tension rises, and the group briefly fears that something went wrong. That is, until a black panel appears showing Gojo standing tall in a different location.
This narrative choice—showing Gojo in isolation rather than with the group—symbolizes two things:
- The psychological distance created by his time in the Prison Realm.
- His readiness to confront the threats that emerged in his absence.
Characters involved:
- Angel/Hana Kurusu: Their technique is essential to breaking the seal. Hana’s character is particularly humanized in this chapter—her doubt, fear, and eventual relief emphasize how dangerous and uncertain this mission was.
- Yuji Itadori and Megumi Fushiguro (mentioned/appearing briefly): They represent the emotional core of the new generation, waiting anxiously for their mentor’s return.
Gojo vs. Kenjaku (and Sukuna): Immediate Confrontation
Rather than retreating to safety or regrouping, Gojo immediately confronts Kenjaku. It’s a bold narrative move, showing that Gojo has no intention of playing defense.
But just as the tension builds between the two, Sukuna appears—now inhabiting Megumi’s body. This is the true gut punch of the chapter. Seeing Gojo lock eyes with Sukuna, knowing that his dear student is now possessed by his greatest enemy, adds an intense emotional and ethical layer to what’s otherwise a power struggle.
This moment sets up the inevitable showdown between Gojo and Sukuna, the two strongest entities in the Jujutsu Kaisen world. Gojo’s smirk at the end of the chapter says it all—he’s back, and he’s ready for war.
Characters involved:
- Satoru Gojo: His return dominates the chapter. From philosophical musings to a direct challenge, his presence is commanding. Importantly, he shows no signs of mental instability—suggesting that Gojo has either mastered the mental effects of timelessness or is suppressing it.
- Kenjaku: Calm and unphased, Kenjaku’s dialogue reveals that he expected Gojo’s return. His continued manipulation of events suggests he’s always three steps ahead.
- Ryomen Sukuna (in Megumi’s body): Sukuna’s smug, cruel demeanor contrasts sharply with Gojo’s composed confidence. His possession of Megumi adds emotional complexity to their rivalry.
Themes: Time, Isolation, and Resolve
This chapter expertly juggles supernatural mechanics and psychological consequences. The Prison Realm’s lack of time flow becomes more than a plot device—it’s a metaphor for disconnection and mental fortitude.
The philosophical undertones are clear:
- What does it mean to return to a world that moved on without you?
- How do relationships shift when time is experienced differently by different people?
- Can power truly overcome isolation?
Gojo’s calmness upon return suggests he has mentally prepared for this moment. Whether that’s a sign of growth or trauma will likely play out in future chapters.
Why Chapter 221 Is a Game-Changer
The last panel—Gojo facing Sukuna—reignites a rivalry readers have been speculating about for years. But there’s more at stake than just power levels. This isn’t merely a “who’s stronger” debate. Sukuna has taken over the body of Gojo’s protégé, Megumi. So, this fight will also be about rescuing a soul, not just winning a battle.
Moreover, Kenjaku’s presence means this isn’t a simple one-on-one duel. The old generation’s ideologies (Kenjaku’s manipulation, Gojo’s idealism) clash with new world chaos, represented by Sukuna’s unpredictable cruelty.
Gojo’s Return Changes Everything
Chapter 221 delivers not just a plot payoff, but an emotional and thematic triumph. Gojo’s release marks a shift in the narrative tone—from survival and grief to vengeance and reclamation.
Every character plays a critical role: from Hakari’s analysis, Angel’s release technique, to the silent emotional stakes that surround Yuji and Hana. But the heart of this chapter is Gojo—calm, powerful, and now, perhaps more resolute than ever.
His next battle may be the greatest in modern jujutsu history—not just in terms of power, but in what it represents: the battle for the soul of the world and for the redemption of the people he loves.
