The wait for the weekend release is over as significant leaks for Jujutsu Kaisen Modulo Chapter 21 have surfaced online, offering a complete look at the upcoming events. 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.
This chapter marks a pivotal turning point, featuring a shocking alliance between Itadori and Maru, along with the terrifying return of a fan-favorite villain. The narrative depth expands as we witness the mechanics of a new world order known as “Harmony,” designed to eradicate Cursed Spirits forever.

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.
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”.
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.

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 chapter concludes with a massive cliffhanger as Maru and Yuji enter the realm where souls pass through, coming face-to-face with Mahito. 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.
Jujutsu Kaisen Modulo Chapter 21 delivers on emotional depth and high-stakes lore, bringing Yuki Tsukumo’s dream back into focus through Itadori’s actions. With Dabura’s Domain Expansion active and Mahito’s soul cornered, the stage is set for a fundamental rewriting of the world’s laws.
