When Gege Akutami concluded the original Jujutsu Kaisen series, fans wondered if the complex and beloved power system had reached its peak. Little did they know that the universe was about to expand in ways nobody could have predicted. Jujutsu Kaisen’s power system just got a massive upgrade with the introduction of Modulo, the official sequel that takes the cursed energy framework from Earth-bound mechanics to cosmic proportions.
Set 68 years after the Culling Game in 2086, Jujutsu Kaisen Modulo introduces elements that fundamentally transform how we understand jujutsu sorcery. From alien races with their own version of cursed energy to mysterious ores that can manipulate all forms of power, the sequel doesn’t just add to the existing system—it revolutionizes it entirely. Let’s dive deep into how Modulo has upgraded JJK’s power system and what it means for the future of this beloved universe.
From Earth to Cosmos: The Simurian Invasion of Jujutsu Lore
The most significant upgrade to Jujutsu Kaisen’s power system comes with the introduction of the Simurians, an alien race that arrives on Earth in 2086 seeking refuge. These aren’t just extraterrestrial beings with advanced technology—they’re beings who possess their own form of jujutsu sorcery, effectively proving that cursed energy isn’t unique to Earth.
Simurians have evolved their own version of cursed energy called Rolloluca, which they channel through a third eye. This biological difference alone creates fascinating implications for how power works in the JJK universe. While human sorcerers generate cursed energy through negative emotions and innate talent, Simurians produce Rolloluca through their third eye, suggesting a completely different evolutionary path to similar abilities.
What makes this particularly fascinating is that Rolloluca appears to be more destructive and versatile than traditional cursed energy—at least initially. Early chapters of Modulo suggest that Simurian abilities operate on different rules and principles, potentially making them more powerful than even the strongest human sorcerers. However, as we’ll discover, this power comes with its own limitations and vulnerabilities.
The introduction of Simurians also raises profound questions about the nature of cursed energy itself. If multiple species across the universe can develop similar power systems, what does that say about the fundamental laws of the JJK universe? Is cursed energy a universal force like gravity or electromagnetism, manifesting differently based on biological and environmental factors?
Rolloluca: The Alien Cursed Energy That Changes Everything
At the heart of Modulo’s power system upgrade is Rolloluca, the Simurian equivalent of cursed energy. This isn’t just a reskin of existing mechanics—it’s a fundamentally different approach to energy manipulation that expands the possibilities of what jujutsu sorcery can do.
Rolloluca shares some similarities with human cursed energy but operates on distinct principles. While human cursed energy is generated through negative emotions and mental fortitude, Rolloluca is produced through the Simurian third eye, suggesting a more biological and less emotional foundation. This difference could explain why Rolloluca seems more volatile and potentially more powerful than its human counterpart.
One of the most intriguing aspects of Rolloluca is its purity and potential. Certain Simurians, particularly the twins Maru and Cross, possess Rolloluca of exceptional purity that makes them stand out even among their own kind. This suggests that, like human cursed energy, Rolloluca can vary in quality and potency based on individual factors.
The introduction of Rolloluca also creates fascinating comparative possibilities. How does it stack up against the cursed energy of legendary sorcerers like Satoru Gojo or Ryomen Sukuna? Can it be used in similar ways—creating domain expansions, manipulating shikigami, or performing reverse cursed technique? These questions open up entirely new avenues for power development and combat scenarios in the JJK universe.
Perhaps most importantly, Rolloluca demonstrates that the principles of jujutsu sorcery aren’t limited to Earth. This cosmic expansion of the power system allows for virtually limitless storytelling possibilities, introducing the idea that there might be countless other species across the universe with their own unique approaches to energy manipulation.
Mul Ore: The Universal Energy Converter That Redefines Power Scaling
If Rolloluca represents the biological evolution of jujutsu sorcery, then Mul ore represents its technological and material evolution. This special ore, found exclusively on the Simurian homeworld, possesses the incredible ability to convert Rolloluca into any form of energy imaginable.
Mul ore is essentially the ultimate power multiplier in the JJK universe. While human sorcerers are limited by their innate cursed energy reserves and the specific applications of their cursed techniques, Mul ore allows Simurians to transform their Rolloluca into literally any type of energy they need. This could include kinetic energy for devastating attacks, electromagnetic energy for technological applications, or even entirely new forms of energy that humans haven’t discovered yet.
The implications of Mul ore for power scaling are staggering. In the original JJK series, power progression was relatively linear—sorcerers grew stronger through training, experience, and occasionally through external factors like cursed objects or special circumstances. With Mul ore, power scaling becomes exponential. A Simurian with access to large quantities of Mul ore could theoretically achieve levels of power that would make even Sukuna seem weak by comparison.
However, Mul ore also introduces new limitations and conflicts. The ore is rare and valuable, leading to wars between Simurian clans over control of Mul mines. The Rumelians and Deskuntes, two major Simurian factions, have been fighting for generations over access to these resources. This conflict has now followed the Simurian refugees to Earth, potentially dragging humanity into an interstellar resource war.
The existence of Mul ore also raises fascinating questions about the relationship between different forms of energy in the JJK universe. If Rolloluca can be converted into any form of energy, does that mean all energy in the universe is fundamentally the same, just manifesting in different ways? This philosophical and scientific dimension adds incredible depth to the power system.
The Kalyan Connection: Bridging Simurians and Cursed Spirits
Perhaps the most shocking revelation in Jujutsu Kaisen Modulo is the connection between Simurians and cursed spirits. Chapter 11 confirms that the Kalyan—mysterious beasts that only the Lumerian tribe of Simurians can control—are actually cursed spirits.
This revelation fundamentally changes our understanding of both cursed spirits and the broader JJK cosmology. If cursed spirits exist on other planets and can be controlled by alien species, what does that say about their nature? Are they universal manifestations of negative energy that take different forms based on local conditions? Or are they something else entirely?
The connection between Kalyans and cursed spirits also creates immediate narrative tension. Human sorcerers have been exorcising cursed spirits for centuries, believing them to be purely malevolent manifestations of human fear and suffering. Now, they discover that these beings might be connected to the Simurians, potentially making their exorcism acts of war against an alien race.
This revelation could lead to conflict between humans and Simurians, as the Simurian elder Boro was horrified to learn that humans have been “butchering” Kalyans. If the Simurians discover that human sorcerers routinely kill what are essentially their sacred or connected beings, it could easily escalate into interstellar war.
The Kalyan connection also suggests that the JJK universe is much more interconnected than previously believed. The lines between different types of beings—humans, cursed spirits, and now aliens—are becoming increasingly blurred, hinting at a grand unified theory of existence that could explain everything from cursed energy to the nature of souls.
A New Power Hierarchy: Grade 1 Sorcerers and Measured Progression
Unlike the original Jujutsu Kaisen, which introduced incredibly powerful characters like Satoru Gojo and Ryomen Sukuna from the very beginning, Modulo takes a more measured approach to power progression. The sequel has deliberately avoided introducing Special Grade sorcerers early on, instead focusing on Grade 1 threats and building tension gradually.
This approach represents a significant upgrade to the power system’s narrative structure. By starting with more manageable threats, Modulo allows readers to appreciate the nuances of the new power mechanics without being overwhelmed by cosmic-level abilities from the outset. Characters like Masaki Takeda, who demonstrates power rivaling Grade 1 sorcerers, provide credible threats without immediately jumping to universe-breaking levels of strength.
This measured progression also allows for better character development and power exploration. Protagonists like Tsurugi and Yuka can grow into their abilities gradually, learning to navigate both traditional jujutsu techniques and the new Simurian-influenced powers. The awakening of Maru’s third eye, for example, is presented as a significant moment of power development rather than just another routine power-up.
The absence of Special Grade sorcerers in the early chapters also creates anticipation. Readers know that these incredibly powerful beings exist in the universe, and their eventual introduction will have much more impact because of the careful buildup. This approach demonstrates a more sophisticated understanding of power scaling and narrative pacing.
Third Eye Mechanics: Biological Evolution of Jujutsu Abilities
One of the most fascinating upgrades to the power system is the introduction of third eye mechanics for Simurians. Unlike human sorcerers who rely on training, emotion, and innate talent to manipulate cursed energy, Simurians use their third eye as a biological organ for channeling Rolloluca.
This biological approach to energy manipulation opens up entirely new possibilities for power development. The third eye isn’t just a metaphor or spiritual concept—it’s a physical organ that can be trained, damaged, or enhanced. This creates new vulnerabilities and strengths that don’t exist in the human jujutsu system.
For example, when Simurians cry from their third eye, it can be deadly for them, suggesting that the organ is intimately connected to their life force. This creates a fascinating risk-reward dynamic where using their powers might literally cost them their lives if pushed too far.
The third eye also suggests different evolutionary paths to power. While humans developed jujutsu sorcery through mental and emotional refinement, Simurians evolved it through biological adaptation. This raises intriguing questions about whether other species might have developed completely different approaches to energy manipulation—perhaps through technological means, collective consciousness, or other biological adaptations we haven’t imagined yet.
Gender Dynamics in Power: A New Approach to Cursed Energy
Jujutsu Kaisen Modulo introduces another significant upgrade to the power system through its exploration of gender dynamics in energy manipulation. Chapter 11 reveals that only male Simurians can wield cursed energy, while female Simurians can see curses but cannot use them.
This limitation creates fascinating social and power dynamics within Simurian society. It suggests that power distribution isn’t equal among all members of the species, leading to specialized roles and potentially complex social structures. Female Simurians, while unable to directly wield power, might serve as scouts, strategists, or mediators due to their ability to perceive curses.
This gender-based limitation also contrasts interestingly with human jujutsu society, where both men and women can become powerful sorcerers. Characters like Nobara Kugisaki, Maki Zenin, and Yuki Tsukumo demonstrate that gender is no barrier to power in human jujutsu society. The Simurian approach suggests that different species might have evolved completely different solutions to the challenge of energy manipulation.
Resource Wars and Power Politics: The Real Cost of the New System
The introduction of Mul ore and the conflict between Rumelians and Deskuntes adds a layer of political and economic complexity to the power system that wasn’t present in the original JJK series. Power isn’t just about individual strength anymore—it’s about resources, territory, and interstellar politics.
The Rumelians, who possess large reserves of Mul ore hidden in Naunax, represent the established power structure that controls valuable resources. The Deskuntes, who pursue the Rumelians for their Mul reserves, represent the ambitious challengers seeking to upset the balance of power. This conflict has now spilled over to Earth, potentially dragging humanity into a war they don’t understand.
This political dimension makes the power system feel more realistic and consequential. In the original JJK, conflicts were primarily personal or ideological—individuals and organizations fighting over beliefs, revenge, or power for its own sake. In Modulo, the stakes are higher and more complex, involving the survival and prosperity of entire species.
The Future of Jujutsu: Infinite Possibilities
Jujutsu Kaisen Modulo’s massive upgrade to the power system opens up infinite possibilities for future storytelling. With the introduction of alien races, new forms of energy, and interstellar conflicts, the JJK universe has expanded from a relatively contained story about Japanese high school students fighting curses to an epic space opera with cosmic implications.
The sequel suggests that we’ve only scratched the surface of what’s possible in this universe. If Simurians exist with their own form of jujutsu sorcery, what other species might be out there? What other forms of energy manipulation might exist? Could there be entire civilizations built around different principles of power that we haven’t even imagined?
The measured approach to power progression also suggests that we’re in for a long and satisfying journey. By avoiding the temptation to immediately introduce universe-breaking powers, Modulo sets up a narrative structure that can grow and evolve organically, allowing readers to discover the depths of this expanded universe alongside the characters.
Conclusion: A Bold New Chapter for Jujutsu Kaisen
Jujutsu Kaisen’s power system just got a massive upgrade with Modulo, and the changes are more than just cosmetic—they’re fundamental to how we understand the JJK universe. From the introduction of Rolloluca and Mul ore to the revelation of connections between Simurians and cursed spirits, the sequel has transformed a relatively contained power system into a cosmic framework with infinite possibilities.
What makes this upgrade so brilliant is how it builds on the foundation of the original series while expanding it in logical and exciting ways. The core principles of jujutsu sorcery remain intact, but they’re now part of a much larger tapestry that includes alien biology, interstellar politics, and universal energy mechanics.
As Modulo continues to unfold over its planned six-month serialization, fans can look forward to discovering even more about this expanded universe. The careful pacing, measured power progression, and intricate world-building suggest that we’re in for a journey that will redefine what’s possible in the world of jujutsu sorcery.
Jujutsu Kaisen’s power system just got a massive upgrade, and the best part is that we’ve only seen the beginning. The cosmic expansion of the JJK universe through Modulo proves that even the most well-established systems can evolve in exciting and unexpected ways, setting the stage for countless stories yet to be told.
