The world of Jujutsu Kaisen has always been defined by epic conflicts, from the Shibuya Incident to the climactic battle against Ryomen Sukuna that scarred Shinjuku and changed the jujutsu world forever. However, Gege Akutami’s sequel, Jujutsu Kaisen Modulo, is setting the stage for a conflict that makes even Sukuna’s devastating reign of terror seem small in comparison. Jujutsu Kaisen sets up a battle even bigger than the Sukuna war through the introduction of 50,000 alien warriors known as Simurians, each possessing powers equivalent to jujutsu sorcerers, creating an unprecedented threat that could dwarf anything the original series ever presented.
The Simurian Invasion: 50,000 Reasons to Fear the Future
When the Simurians arrived on Earth in 2086, they came not as conquerors but as refugees seeking asylum. However, their sheer numbers make them an existential threat unlike anything Japan’s jujutsu society has ever faced. According to official records, nearly 50,000 Simurians arrived aboard their mothership Naunax, each individual possessing Rolloluca—their version of cursed energy—channeled through a third eye.
To put this in perspective, during the Sukuna war, Japan faced primarily one overwhelming threat (Sukuna himself) supported by various curse users and cursed spirits. The Simurian presence represents 50,000 potential threats, each capable of wielding jujutsu-like abilities. Even if most are relatively low-level sorcerers, the sheer scale of their numbers creates a logistical nightmare for Japan’s already depleted jujutsu society.
The invasion has been officially classified as a Special Grade incident, placing it on the same threat level as Sukuna’s attack on Shinjuku. This classification alone speaks volumes about the potential devastation these aliens could unleash if hostilities break out. Unlike previous threats that were contained to specific locations or involved limited numbers of combatants, the Simurian presence represents a sustained, widespread threat that could overwhelm Japan’s defenses through sheer force of numbers.
Power Parallels: How the Simurians Match and Exceed Sukuna’s Legacy?
What makes the potential Simurian conflict particularly terrifying is that their power structure mirrors and potentially exceeds that of the Sukuna era. While Sukuna was undoubtedly the most powerful individual threat the jujutsu world ever faced, the Simurians bring multiple threats of similar magnitude to the table.
Dabura: The Sukuna-Level Threat
At the forefront of the Simurian threat stands Dabura, their leader who is explicitly stated to be on the same level as Sukuna himself. This isn’t hyperbole—multiple sources within the story confirm that Dabura possesses power comparable to the King of Curses. Imagine facing another Sukuna, but this time with the backing of thousands of other powerful warriors rather than operating alone.
Dabura’s presence alone would be enough to classify this conflict as potentially catastrophic, but he’s far from the only Simurian with extraordinary power. The twins Maru and Cross are both described as Special Grade-level threats, possessing Rolloluca of exceptional purity that makes them stand out even among their own kind. These three individuals alone represent a threat level comparable to the most powerful figures from the original series.
The Army of Sorcerers
Beyond these elite fighters, the Simurian forces include thousands of warriors with varying levels of jujutsu-like abilities. While not all may reach Special Grade status, even Grade 1 or Grade 2 sorcerers in those numbers would present an unprecedented challenge. During the original series, Japan struggled with a shortage of sorcerers to handle routine curse exterminations. Facing 50,000 potential enemies would stretch their resources beyond breaking point.
The military implications are staggering. Traditional jujutsu tactics that worked against individual curses or small groups of curse users would be ineffective against an organized army of this size. Japan would need to develop entirely new strategies, potentially involving mass combat techniques and coordinated operations on a scale never before seen in the jujutsu world.
The Irreconcilable Conflict: Kalyans, Cursed Spirits, and Cultural Warfare
Perhaps the most tragic aspect of this brewing conflict is that it stems from a fundamental misunderstanding that may be impossible to resolve peacefully. The core issue revolves around the relationship between Simurians and Kalyans—beings that have recently been revealed to be essentially the same as Earth’s cursed spirits.
The Kalyan Connection
Chapter 11 of Jujutsu Kaisen Modulo delivered a bombshell revelation: Kalyans, the beasts native to the Simurian planet that are revered by the Lumerian tribe, are actually cursed spirits. This discovery creates an immediate and seemingly insurmountable barrier to peaceful coexistence between humans and Simurians.
For human jujutsu sorcerers, exorcising cursed spirits is not just their duty—it’s essential for protecting humanity from supernatural threats. Cursed spirits feed on negative human emotions and cause death and destruction wherever they manifest. The entire purpose of jujutsu society is to eliminate these threats.
For the Simurians, particularly the Lumerian tribe, Kalyans are sacred beings. They’re described as deities who gave the Simurians their Rolloluca (cursed energy). The idea that humans would “butcher” these revered beings is horrifying to them, as demonstrated by the Simurian elder Boro’s tearful reaction to witnessing humans exorcising what he perceived as Kalyans.
A Clash of Fundamental Values
This isn’t merely a political disagreement that can be negotiated away—it’s a fundamental clash of worldviews and values. Humans see cursed spirits as threats to be eliminated; Simurians see them as sacred beings to be protected. There’s no middle ground where both sides can be satisfied.
The implications are devastating. Every time human sorcerers perform their duty by exorcising a curse, they’re potentially committing what the Simurians would consider sacrilege. Conversely, if Simurians attempt to protect what they see as sacred Kalyans, they’re endangering human lives by allowing cursed spirits to run free.
This cultural and religious divide makes peaceful coexistence virtually impossible. Even if individual Simurians like Maru genuinely want to live in harmony with humans, the fundamental conflict over how to treat cursed spirits/Kalyans will eventually drive the two species apart.
The Stakes: Why This War Could Be More Devastating Than Sukuna’s Reign?
While Sukuna’s battle was certainly catastrophic, the potential Simurian war threatens to be far more destructive for several key reasons:
Geographic Scale
Sukuna’s devastation was largely contained to Shinjuku, creating a localized disaster zone. A war with 50,000 Simurians would likely spread across all of Japan, potentially spilling over into other countries. The geographic scope alone makes this conflict potentially orders of magnitude more destructive.
Sustained Conflict
The Sukuna battle, while intense, was relatively brief in the grand scheme of things. A war with the Simurians could drag on for years or even decades, creating a state of perpetual conflict that would gradually wear down Japan’s resources and population. This isn’t a single battle to be won or lost—it’s a potential war of attrition that Japan cannot afford to fight.
Civilian Impact
During the Sukuna incident, civilians were certainly affected, but the conflict primarily involved sorcerers and curses. A full-scale war with the Simurians would inevitably drag civilians into the conflict, either as collateral damage or as targets. With 50,000 alien warriors potentially hostile, the civilian death toll could be astronomical.
Global Implications
While the original Jujutsu Kaisen was largely focused on Japan, a conflict with the Simurians would have global repercussions. Other nations would inevitably get involved, either as allies to Japan or as opportunistic powers seeking to exploit the chaos. This could escalate into a worldwide crisis far beyond anything the jujutsu world has ever faced.
Japan’s Desperate Search for Hope: The Yuji Factor
In the face of this overwhelming threat, Japan’s jujutsu society is desperately searching for any advantage they can find. One name keeps coming up in discussions of potential defense: Yuji Itadori.
The Need for a Deterrent
With the Simurian threat looming, many in Japan’s jujutsu society believe they need their own Sukuna-level deterrent. Yuji Itadori, who played a crucial role in defeating the original Sukuna, represents their best hope for surviving the coming conflict. His unique abilities and experience make him potentially invaluable in the fight against the Simurians.
The search for Yuji has become a priority for Japan’s jujutsu authorities. They understand that without someone of his caliber on their side, they stand little chance against the combined might of 50,000 Simurian warriors led by Sukuna-level individuals like Dabura.
The Generational Shift
Interestingly, the burden of defending Japan seems to be falling to a new generation. The protagonists of Modulo are Yuka and Tsurugi Okkotsu, grandchildren of Yuta Okkotsu and Maki Zenin. This generational shift suggests that the original heroes may be unavailable or unwilling to fight, leaving the defense of humanity to their descendants.
This creates a fascinating dynamic where the new generation must step up to face a threat even greater than what their grandparents confronted. It’s a testament to how the stakes have been raised in the world of Jujutsu Kaisen.
The Fragile Peace: Why War Seems Inevitable?
Despite efforts to establish peaceful coexistence between humans and Simurians, all signs point toward eventual conflict. Several factors make war increasingly likely:
Broken Trust
The initial hope for peaceful coexistence has been shattered by the revelation about Kalyans and cursed spirits. Trust between the two species has been severely damaged, and rebuilding it seems nearly impossible given the fundamental disagreement about how to treat these beings.
Internal Simurian Politics
Not all Simurians share the same goals. While characters like Maru advocate for peaceful coexistence, others, including his twin brother Cross, have more aggressive agendas. This internal division means that even if some Simurians want peace, others may force conflict.
Human Prejudice
On the human side, fear and prejudice against the alien visitors are growing. The sheer scale of the Simurian presence—50,000 beings with unknown powers—makes many humans uncomfortable and suspicious. This fear could easily translate into hostility, especially if provoked by Simurian actions.
Resource Competition
Earth’s resources are limited, and adding 50,000 new beings to the population creates inevitable competition. While the Simurians claim to be refugees, their long-term intentions remain unclear, and many humans worry about the strain they’ll place on Earth’s ecosystems and economies.
The Tactical Challenge: Fighting an Army of Sorcerers
From a tactical perspective, facing the Simurians presents unique challenges that Japan’s jujutsu society has never had to confront:
Mass Combat Techniques
Traditional jujutsu techniques are designed for individual combat or small team operations. Fighting an army of 50,000 would require entirely new approaches to mass combat. Japan’s sorcerers would need to develop techniques capable of affecting multiple targets simultaneously or coordinating large-scale operations.
Intelligence Gathering
Understanding Simurian abilities and tactics will be crucial for survival. However, with 50,000 individuals, each potentially possessing unique powers, gathering comprehensive intelligence seems nearly impossible. Japan’s sorcerers would be fighting partially blind, unable to predict what they might face in any given encounter.
Supply Lines and Logistics
Unlike curses that simply manifest, Simurians are physical beings with physical needs. They require food, water, shelter, and medical care. This creates both vulnerabilities and opportunities. Disrupting their supply lines could weaken their fighting ability, but it also means they can fortify positions and establish bases of operation.
Terrain and Environment
The Simurians could potentially use Japan’s urban and rural environments to their advantage, creating fortified positions or using civilian populations as shields. This would force human sorcerers to fight on unfamiliar terrain while trying to minimize civilian casualties.
The Cosmic Implications: Jujutsu Kaisen’s Universe Expands
Perhaps the most significant aspect of this brewing conflict is how it expands the scope of the Jujutsu Kaisen universe. The original series suggested that cursed energy was unique to Earth, but Modulo reveals that it’s actually a universal phenomenon with different manifestations across different species.
Universal Cursed Energy
The existence of Rolloluca as the Simurian version of cursed energy suggests that similar forces exist throughout the universe. This opens up fascinating possibilities for future stories and conflicts, potentially involving other alien species with their own unique approaches to energy manipulation.
The Nature of Cursed Spirits
The revelation that Kalyans are essentially the same as cursed spirits raises profound questions about the nature of these beings. Are they universal manifestations of negative energy that take different forms based on local conditions? Or are they something else entirely that we’ve only partially understood?
Interconnected Fates
The connection between Simurians and cursed spirits suggests that the fates of different species in the universe may be more interconnected than previously believed. Actions taken on Earth could have repercussions across the cosmos, and vice versa.
Conclusion: The Perfect Storm for an Unprecedented Conflict
Jujutsu Kaisen sets up a battle even bigger than the Sukuna war through a perfect storm of factors: overwhelming numbers, comparable power levels, irreconcilable cultural differences, and the expansion of the series’ scope to cosmic proportions. The Simurian threat represents everything that made Sukuna dangerous—immense power, the potential for widespread destruction, and the ability to challenge the very foundations of jujutsu society—multiplied by thousands.
What makes this conflict particularly compelling is how it grows naturally from the seeds planted in the original series. The questions about the nature of cursed energy, the role of jujutsu sorcerers, and the ethics of their actions are all being explored on a grander scale. The Simurian conflict forces characters and readers alike to confront the implications of a world where multiple species have different relationships with the same fundamental forces.
As Modulo continues to unfold, the path to war seems increasingly inevitable. The fundamental disagreement over how to treat Kalyans/cursed spirits creates a divide that may be impossible to bridge peacefully. When combined with the sheer scale of the Simurian presence and the power of their leaders, the ingredients are in place for a conflict that will make even the devastating Sukuna war seem like a minor skirmish by comparison.
Japan’s jujutsu society stands at a crossroads, facing a threat that could end human civilization as they know it. Their only hope may lie in finding Yuji Itadori and somehow bridging the impossible gap between human and Simurian understanding of the universe. But with each passing chapter, the flames of war grow higher, and the chance for peaceful resolution grows dimmer.
The battle that’s being set up isn’t just bigger than the Sukuna war—it’s potentially the beginning of a new era in the Jujutsu Kaisen universe, where the fate of humanity hangs in the balance against cosmic forces beyond imagination. Jujutsu Kaisen has truly set up a battle even bigger than the Sukuna war, and the consequences will reshape the series’ world forev
