Although the official release is still a few days away, insiders have translated the full chapter, revealing that authors Gege Akutami and Yuji Iwasaki are accelerating the narrative toward a massive climax involving the fate of all cursed energy.

The narrative depth expands as we witness the mechanics of a new world order known as “Harmony,” designed to eradicate Cursed Spirits forever.

Jujutsu Kaisen Modulo Chapter 21 Why Did Tsurugi Choose to Forfeit Against Maru?

The chapter opens with an emotional flashback involving Maki Zenin and her grandson, Tsurugi, which contextualizes the young sorcerer’s decision on the battlefield. Maki imparts a crucial lesson about power and sacrifice, referencing the tragic loss of her sister Mai and urging Tsurugi never to discard what “didn’t need to be lost.” This philosophical weight leads Tsurugi to drop his sword during his duel with Maru, realizing that a victory achieved through current methods would result in a corrupted future.

Maru is visibly moved by this act of mercy, breaking down in tears as the manifestation of Rika appears briefly before fading away. This moment signifies a shift from pure combat to ideological resolution, setting the stage for the alliance that follows.

Maki’s Wisdom: She regrets losing Mai and warns Tsurugi against similar sacrifices.
The Surrender: Tsurugi senses that winning would be “wrong” and stops fighting.
Emotional Shift: Maru’s tears and Rika’s appearance signal a change in the battle’s dynamic.

What Is Dabura’s New Domain Expansion Jujutsu Kaisen Modulo Chapter 21?

Sensing the shift in the battlefield and the specific Cursed Technique signature of Maru, the antagonist Dabura realizes the protagonists are plotting something drastic. Refusing to let them dictate the flow of battle, the Simurian leader unleashes his ultimate technique to end the conflict immediately. He activates his Domain Expansion: “Boundary Between Worlds: Inverse Transcendence”.

The patchwork curse, who served as Yuji’s nemesis for years, appears genuinely terrified to see that his arch-enemy is still alive and capable of entering this plane.

This expansion appears to be a direct counter to the collaborative efforts of the sorcerers, threatening to sever the connection between dimensions. For more context on the lead-up to this battle, check out our analysis of Jujutsu Kaisen Modulo Chapter 20 spoilers.

The Domain: “Boundary Between Worlds: Inverse Transcendence” is revealed.

How Will Itadori and Maru Achieve “Harmony”?

In a shocking twist, Maru transports Itadori to a dimension housing the oldest known Karyan, where Yuji reveals he was briefed on these beings by Todo. The duo plans to initiate “Harmony,” a metaphysical state that would merge humans and Simurians to create a world where Cursed Spirits can no longer be born. This plan requires three specific components: the Cursed Energy from Yuta’s ring, the material from the Simurian spaceship, and their combined Cursed Techniques.

To facilitate this, Yuji Itadori hands over Yuki Tsukumo’s research book on souls, effectively aiming to fulfill her lifelong dream. This legacy play connects the current arc back to the original series’ lore regarding the eradication of curses.

The Goal: Create a world without Cursed Spirits via “Harmony.”
Key Ingredients: Yuta’s Ring, Spaceship material, and specific Cursed Techniques.
Yuki’s Legacy: Her book on souls is the final key to the plan.

Is Mahito Alive in Chapter 21?

The patchwork curse, who served as Yuji’s nemesis for years, appears genuinely terrified to see that his arch-enemy is still alive and capable of entering this plane.

This meeting is not for combat, but to utilize the soul realm to trigger the “Harmony” event, signaling the endgame of the series. Readers worried about delays can rest easy, as the manga will continue without a hiatus next week.

The Return: Mahito appears in the soul passage realm.
The Reaction: Mahito is visibly frightened of Itadori’s presence.
