Jujutsu Kaisen Modulo Manga Chapter 21

⭐ Jujutsu Kaisen Modulo Chapter 21 — Prediction

The Jujutsu Kaisen Modulo Manga storyline is quietly crossing its most dangerous threshold. Not because of stronger enemies. Not because of new cursed techniques. But because every major character now believes they are justified.

Jujutsu Kaisen Modulo Manga Chapter 20 reshaped the battlefield in a way that feels far more fragile than explosive. Dabura’s rapid mastery of Reverse Cursed Technique, Mahoraga’s continuous adaptation cycle, and Tsurugi’s irreversible binding vow against Maru have all created a conflict that can no longer be solved by overwhelming force alone.

These Jujutsu Kaisen Modulo Manga Chapter 21 predictions focus on a single, unsettling question: What happens when the people who can stop the disaster are also the ones accelerating it?

Context Recap: What Chapter 19 and Chapter 20 Established

Before we look forward, it’s important to understand what the story has deliberately prepared.

Chapter 19 The battlefield stops being personal

Chapter 19 pushed the conflict out of isolated duels and into public consequence.

The Dabura vs. Mahoraga clash expanded far beyond a controlled combat zone. Spatial instability, collapsing barriers, and residual cursed energy surges forced emergency evacuation sectors across Tokyo. For the first time in the Modulo arc, the narration framed the fight as a civilian disaster, not just a sorcerer conflict.

At the same time, Tsurugi formally activated his binding vow against Maru. Not as a sudden power-up but as a carefully prepared exchange: His remaining physical lifespan and cursed output stability traded for a fixed, overwhelming combat window. Chapter 19 ended by removing ambiguity. The vow could not be undone.

Chapter 20 Power starts making decisions on its own

Chapter 20 then changed the emotional texture of the arc. Dabura revealed functional mastery of RCT at combat speed, healing, and correcting cursed flow without disrupting his offensive pressure. Mahoraga continued adapting not merely to techniques, but to tactical rhythm itself. More quietly, Yuji Itadori re-entered the scene. Not as a fighter. As a limiter. His presence didn’t interrupt the conflict; it reframed it. That silence is what Chapter 21 must now resolve.

Prediction 1: Yuji’s Next Intervention Will Be Deliberately Delayed

One of the strongest signals coming out of Chapter 20 is restraint. Yuji did not rush forward. He did not attempt to suppress either Dabura or Mahoraga. In Jujutsu Kaisen Modulo Manga Chapter 21, Yuji is more likely to observe longer than readers expect. This is not hesitation. It is an assessment.

Yuji’s growth in the Modulo arc has centered on understanding when intervention creates worse outcomes than inaction. The evacuation zones, the overflow of low-grade cursed spirits, and the political collapse shown in recent chapters have taught him that stopping one fight may trigger several others.

His next intervention will likely occur only after one of two thresholds is crossed:

• Civilian sectors become directly targeted by the clash, or
• Tsurugi’s binding vow begins to destabilize Maru’s technique in ways that threaten surrounding zones.

Yuji’s interference too early risks forcing Dabura and Mahoraga into escalation rather than resolution. Chapter 21 may show him choosing not to interfere at all, and that decision itself becomes the tension.

Prediction 2: Dabura vs. Mahoraga Will Escalate Through Reversal, Not Power

The most important shift in Dabura’s position is not his speed. It is control. With functional RCT now stabilized, Dabura is no longer constrained by the same recovery windows Mahoraga has been exploiting. This opens the door to a potential cursed technique reversal, something Mahoraga has not yet adapted to.

In Jujutsu Kaisen Modulo Manga Chapter 21, Dabura’s escalation is far more likely to come through technical inversion rather than raw output. Mahoraga’s adaptation historically responds to repeated patterns. A reversal, especially one that alters cursed flow logic rather than attack structure, forces a recalibration period.

That recalibration window may be Dabura’s only real opportunity to land meaningful damage.

However, the fight will not conclude cleanly.

The narrative structure suggests escalation, not closure. Mahoraga may begin adapting to Dabura’s recovery patterns, themselves countering not the attacks, but the healing intervals that allow Dabura to maintain pressure. The fight becomes less about killing power and more about who can exhaust the other’s adaptive limits first.

Prediction 3: The Fight Will Spill Into the Larger Crisis

One major detail from Chapter 20 cannot be ignored. Cursed spirit outbreaks are no longer localized. They are spreading. Jujutsu Kaisen Modulo Manga Chapter 21 is likely to shift part of the Dabura vs. Mahoraga focus toward what their collision is unleashing across the city.

Quantity, not quality, becomes the next threat.

Low-grade cursed entities flooding evacuation corridors would force sorcerer redeployments and thin out remaining defenders. This creates indirect pressure on Yuji and the command structure.

The duel becomes strategically dangerous even if neither fighter loses.

Prediction 4: Tsurugi’s Binding Vow Will Begin Breaking Maru’s Technique, Not His Body

The most tragic tension heading into Chapter 21 is not who wins between Tsurugi and Maru. It is what remains afterward. Tsurugi’s binding vow was not designed for instant victory. It was designed for guaranteed destabilization.

Maru’s cursed technique, already built on complex spatial and causal manipulation, requires internal equilibrium. Chapter 21 is likely to show that Tsurugi’s amplified output is not damaging Maru physically, but structurally.

Expect:

• delayed technique activation
• inconsistent targeting
• feedback loops within Maru’s domain constructs

Maru may remain standing.

But his technique may not. This creates a terrifying possibility: even if Tsurugi collapses after the vow expires, Maru may be left unable to safely relocate Simurians or stabilize displaced zones. Victory becomes functionally hollow.

Prediction 5: Yuji’s Choice Will Be Between Two Collapses

If Yuji finally intervenes in Chapter 21, the intervention will not be aimed at Dabura or Mahoraga. It will be aimed at the consequences. Yuji may choose to redirect resources toward evacuation defense instead of battle suppression.

This would be a subtle but powerful statement. He is no longer trying to control the strongest individuals. He is trying to protect what the strongest are breaking.

TL;DR: 

• Yuji delays intervention to prevent forced escalation
• Dabura attempts a cursed technique reversal against Mahoraga
• Mahoraga adapts to healing patterns rather than attacks
• Cursed spirit outbreaks expand citywide
• Tsurugi destabilizes Maru’s technique through his binding vow
• Chapter 21 prioritizes fallout over victory

Final Thoughts

These Jujutsu Kaisen Modulo Manga Chapter 21 predictions reflect a story that is no longer centered on defeating enemies. It is centered on limiting damage. The arc is quietly reframing heroism. Not as domination. But as damage control.
