Article summary
Jujutsu Kaisen Modulo is an official near-future spin-off manga written and supervised by Gege Akutami and published by Shueisha in Weekly Shonen Jump. The story is set in the year 2086, exactly 68 years after the Culling Game, and continues within the same canonical universe as the original Jujutsu Kaisen series.
The plot introduces an alien race called the Simurians, whose sudden arrival on Earth triggers a new conflict that blends jujutsu sorcery with science-fiction themes. The main protagonists are siblings Okkotsu Maken and Okkotsu Yuka, descendants of the original Okkotsu bloodline, accompanied by a Simurian envoy known as Inspector Maru.
The series debuted on September 8, 2025 (Weekly Shonen Jump Issue #41) and follows a weekly release schedule across Jump, Viz, and Manga Plus. Akutami has confirmed that Modulo is a short-term serialization, planned for approximately three volumes (around 21 chapters), with publication expected to conclude in spring 2026.
What Is the Jujutsu Kaisen Modulo Arc?
The Jujutsu Kaisen Modulo Arc is an official, canon spin-off that expands the Jujutsu Kaisen universe into a distant future timeline. Rather than retelling past events, Modulo explores how jujutsu sorcery evolves decades after the original story, introducing extraterrestrial threats and a new generation of sorcerers.
Created and written by Gege Akutami, the arc is positioned as a limited, near-future serialization designed to extend the lore without altering established continuity. It functions as a short, self-contained storyline while remaining fully connected to the original canon.
Official Overview and Premise
The Modulo arc takes place in the year 2086, sixty-eight years after the conclusion of the Culling Game. Humanity’s fragile peace is disrupted when a massive spaceship appears above Earth, carrying an alien race known as the Simurians.
According to official descriptions, more than 50,000 space refugees arrive and request cooperation with Japanese jujutsu authorities. The central mission follows siblings Okkotsu Maken and Okkotsu Yuka, who are sent to Kyoto alongside a Simurian envoy to investigate a mysterious kidnapping case.
The series’ tagline, “Jujutsu sorcerers and aliens!”, summarizes its defining concept. Traditional cursed energy combat is now intertwined with science-fiction elements, as new lifeforms either clash with or cooperate with human sorcerers in a radically changed world.
Publication and Serialization Details
Jujutsu Kaisen Modulo officially debuted in Weekly Shonen Jump Issue #41 on September 8, 2025. From its launch, the series has followed a weekly release schedule, publishing new chapters every Sunday across multiple platforms, including Weekly Shonen Jump, Viz, and Manga Plus. and JJK manga read
Gege Akutami has publicly described Modulo as a short-term project, planned to run for approximately six months. The projected length is three collected volumes, totaling roughly twenty-one chapters.
By early January 2026, the series had already reached Chapter 17, with additional chapters scheduled weekly until its planned conclusion in spring 2026.
Jujutsu Kaisen Modulo Timeline and Setting
Set decades after the original series, the Modulo arc represents the furthest point in the Jujutsu Kaisen timeline ever explored in canon. By placing the story in the year 2086, Gege Akutami shifts the narrative into a transformed world where jujutsu society, technology, and global threats have all evolved. Although the arc introduces aliens and advanced concepts, it is officially framed as a “near-future” continuation rather than a distant science-fiction reboot.
This setting allows Modulo to expand the universe naturally. The legacy of the Culling Game still shapes the world, while modern society now faces challenges that extend beyond curses and sorcerers, pushing jujutsu into an interspecies and planetary conflict.
How Modulo Fits Into Jujutsu Kaisen Canon
The Modulo arc is fully canonical and does not rewrite or contradict any past events. Official descriptions confirm that the story takes place 68 years after the Culling Game, preserving the entire original timeline intact. Rather than functioning as an alternate reality, Modulo is positioned as a direct extension of the same universe.
Akutami has explained that the arc was designed to explore a future timeline without altering established history. The Culling Game is directly referenced, and the world clearly reflects the long-term consequences of that conflict. The protagonists themselves reinforce continuity, as Okkotsu Maken and Okkotsu Yuka descend from major bloodlines connected to characters like Yuta Okkotsu and the Zen’in family.
In this way, Modulo expands the canon instead of revising it. The arc introduces new threats, locations, and themes while respecting the foundation built by the original series.
Key Differences From the Original Series Era
While the core rules of jujutsu remain intact, the Modulo era differs sharply from the original setting in both scale and tone. The most striking change is the presence of extraterrestrial life. The arrival of the Simurians introduces an entirely new category of enemies and allies, shifting the story beyond traditional cursed spirits and rogue sorcerers.
Conflict is no longer limited to curses born from human negativity. Instead, the central tension becomes an interspecies crisis, with tens of thousands of alien refugees entering Earth and disrupting the balance of power. This transforms the stakes from regional disasters into a potential humanity-wide survival threat.
At the same time, society itself has evolved. Advanced technology, international cooperation, and space-age concepts now coexist with cursed energy and sorcery. The result is a hybrid setting where jujutsu battles unfold alongside investigations involving alien envoys, kidnappings, and diplomatic missions.
Together, these changes redefine the Jujutsu Kaisen formula. Modulo preserves the spiritual combat system but places it inside a broader, futuristic conflict that tests how sorcerers protect not just Japan, but the future of humanity itself.
Jujutsu Kaisen Modulo Chapter List (Official)
As the Modulo arc continues to unfold, its chapter structure reflects the difference between Weekly Shonen Jump serialization and the later collected volume releases. The earliest chapters have already been compiled and officially titled in Volume 1, while later installments remain available only through weekly magazine and digital platforms. This distinction is important for readers tracking canon chapter names, since Jump issue titles sometimes differ from the final listings used in tankōbon volumes.
Volume 1 – Confirmed Chapter Titles
The first collected volume of Jujutsu Kaisen Modulo contains the opening seven chapters, each with fully confirmed official titles released by Shueisha. These chapters establish the future setting, introduce the Okkotsu siblings, and begin the conflict with the Simurian refugees.
-
Chapter 1: Special Grade Incident
-
Chapter 2: Deterrence
-
Chapter 3: Swimming Through the Forest
-
Chapter 4: The Boy Who Kept Repeating
-
Chapter 5: Senility
-
Chapter 6: Berserk
-
Chapter 7: The Robbed
These seven chapters form the narrative foundation of the Modulo arc and represent the only portion of the series with finalized, volume-verified titles so far.
Ongoing Weekly Jump Chapters (Uncollected)
Beyond Volume 1, the series continues weekly in Weekly Shonen Jump, with chapters that have not yet been compiled into official volumes. Among these, the most clearly identified are Chapters 8 and 9, which appear as a two-part storyline titled “Dura Val Bobbidi Mechika” (Part 1 and Part 2). These chapters introduce the Simurian warlord who becomes a major figure in the developing conflict.
Chapters 10 through 17 have been released on schedule through Jump, Viz, and Manga Plus, but their final collected titles remain pending volume confirmation. In many cases, early Jump issue titles are provisional and may be adjusted when the chapters are later compiled into tankōbon form.
This distinction explains why readers may encounter minor differences between magazine listings and future volume tables of contents. Until the next volumes are officially published, only the first seven chapters and the two-part Dura Val Bobbidi Mechika arc carry fully verified titles.
Main Characters in Jujutsu Kaisen Modulo
With the timeline now firmly established and the chapter structure unfolding, the Modulo arc shifts its focus to a new generation of jujutsu sorcerers tasked with defending humanity in an unfamiliar era. While the original cast exists only as historical figures, their legacy continues through descendants and successors who now confront threats that extend far beyond curses. At the center of this future conflict stand three key figures whose roles define the early direction of the series.
Okkotsu Maken
Okkotsu Maken serves as the primary protagonist of the Modulo arc and the narrative’s central point of view. Official material identifies him as the grandson of Yuta Okkotsu, directly linking the new storyline to one of the most important figures from the original series. This lineage establishes Maken not only as a powerful sorcerer by heritage, but also as a symbolic continuation of the Okkotsu legacy.
Within the story, Maken leads the investigation into the Simurian arrival and the related kidnapping case in Kyoto. He functions as both a frontline fighter and a tactical decision-maker, coordinating with human authorities and alien representatives alike. His leadership role positions him as the main protector of Earth in this new era, balancing traditional jujutsu methods with the demands of an unprecedented interspecies crisis.
Okkotsu Yuka
Okkotsu Yuka is introduced as Maken’s younger sister and constant combat partner, forming the core sibling duo of the Modulo arc. Like her brother, she is a fully trained jujutsu sorcerer and is officially described as one of Earth’s primary defenders in 2086. Her presence reinforces the generational theme of the series, showing how established bloodlines continue to shape the future of sorcery.
Yuka’s role is more than supportive. She actively participates in frontline missions and plays a crucial defensive function as the conflict with the Simurians escalates. Her family connections also carry narrative weight, as her lineage is implied to trace back to major figures from the original timeline, further anchoring Modulo within established canon. Together with Maken, she represents the new face of jujutsu authority in a rapidly changing world.
Maruru Val Vru Yelvri (Inspector Maru)
Maruru Val Vru Yelvri, commonly referred to as Inspector Maru, is the arc’s most distinctive new character and its primary link to the alien faction. As an official Simurian envoy, he is assigned to accompany the Okkotsu siblings during their investigation, serving as both a diplomatic representative and an active participant in the mission.
Maru’s role introduces constant narrative tension. Although he functions as an ally and guide, his status as a member of the alien race places him in an uneasy position between cooperation and conflict. He embodies the broader uncertainty surrounding the Simurian refugees, whose arrival blurs the line between invaders and victims. Through Maru, the story explores themes of trust, cultural collision, and the fragile balance between humanity and its first extraterrestrial counterparts.
Villains and Antagonistic Forces
With the central heroes established, the Modulo arc introduces a radically different type of opposition. Unlike the original series, where curses and corrupted sorcerers formed the core threats, conflict in Modulo is driven primarily by a species-level confrontation. The arrival of extraterrestrial life shifts the narrative away from curse-born antagonists and toward a complex struggle between humanity and alien refugees, where the line between enemy and ally is often unclear.
The Simurians (Alien Race)
The Simurians are the first large-scale nonhuman faction ever introduced in the Jujutsu Kaisen canon. Official summaries describe them as an alien race whose massive spaceship delivers approximately 50,000 refugees from space to Earth. Rather than arriving as conquerors, they initially present themselves as displaced survivors seeking cooperation and protection.
Their motivations remain deliberately ambiguous. While some Simurians pursue diplomatic engagement through envoys like Inspector Maru, others appear willing to use force to secure their interests. This internal division suggests a structured hierarchy within their society, with leaders, warriors, and official representatives operating under different agendas.
As a result, the Simurians function less as traditional villains and more as a morally complex faction. They are simultaneously victims of circumstance and potential aggressors, creating tension that drives much of the early plot. The central conflict is no longer about exorcising curses, but about managing coexistence, mistrust, and the possibility of interspecies war.
Dura Val Bobbidi Mechika
The first clearly defined hostile leader to emerge from the Simurian faction is Dura Val Bobbidi Mechika, introduced in Chapters 8 and 9. His appearance marks a turning point in the arc, signaling that diplomatic tension is giving way to open confrontation.
Identified as a Simurian warlord, Dura Val Bobbidi Mechika represents the militant side of the alien hierarchy. His two-part introduction establishes him as a commanding figure with the authority to escalate the conflict beyond isolated incidents. Unlike the refugee envoys, his actions suggest preparation for sustained, large-scale engagement against human sorcerers.
Through this character, the Modulo arc begins to frame the broader stakes of the story. What starts as an investigation into kidnappings and refugees evolves into the early stages of a planetary-scale struggle, where jujutsu sorcerers may soon be forced to defend humanity not from curses, but from an organized extraterrestrial power.
Complete Character List (So Far)
With the main heroes and antagonistic forces now established, the Modulo arc presents a compact but clearly structured cast. Because the series is still in its early volumes, the confirmed roster remains limited, focusing on the core human sorcerers and the most prominent Simurian figures. This expandable list format reflects how the cast is expected to grow as new chapters and volumes are released.
Human Sorcerers
The human side of the conflict is currently represented by a small but central group of elite jujutsu sorcerers tasked with protecting Earth from an unprecedented extraterrestrial threat.
-
Okkotsu Maken (乙骨真剣)
The primary protagonist and field leader of the Modulo arc. Grandson of Yuta Okkotsu, Maken leads the investigation into the Simurian arrival and serves as humanity’s main frontline defender in 2086. -
Okkotsu Yuka (乙骨憂花)
Maken’s younger sister and constant combat partner. A fully trained sorcerer and official protector of Earth, Yuka represents the continuation of powerful bloodlines from the original era and plays a key defensive role in the conflict.
Simurian Characters
These are the most prominent named individuals from the alien faction, each representing different aspects of Simurian involvement in human affairs.
-
Maruru Val Vru Yelvri (マルル・ヴァル・ヴル・イェルヴリ) – “Inspector Maru”
A Simurian envoy assigned as a diplomatic liaison to the Okkotsu siblings. Maru operates in the uncertain space between ally and outsider, guiding the investigation while embodying the tension between cooperation and mistrust. -
Dura Val Bobbidi Mechika
A high-ranking Simurian warlord introduced in Chapters 8 and 9. His appearance marks the first major escalation toward organized conflict and establishes the militant wing of the alien hierarchy.
Alien Factions
Beyond individual characters, the story introduces a collective alien presence that reshapes the entire conflict dynamic.
-
Simurians (シムリア星人)
The extraterrestrial race at the center of the arc’s storyline. Numbering approximately 50,000 refugees, the Simurians arrive on Earth seeking survival and cooperation, but internal divisions within their society create the foundation for both diplomacy and warfare. As a faction, they function as both victims and potential antagonists, driving the moral complexity of the Modulo arc.
Connections to the Original Jujutsu Kaisen Series
As the Modulo arc expands the universe into an unfamiliar future, it remains firmly anchored in the foundations of the original Jujutsu Kaisen storyline. Rather than existing as a standalone experiment, Modulo is constructed as a direct continuation that acknowledges past events, preserves established history, and builds forward from the consequences of the Culling Game. This approach allows the series to introduce new concepts while maintaining continuity with the canon that longtime readers recognize.
Lineage and Bloodline Connections
One of the clearest links between Modulo and the original era lies in its focus on descendant characters and inherited legacies. The protagonists themselves embody this continuity. Okkotsu Maken is officially identified as the grandson of Yuta Okkotsu, directly tying the future’s main hero to one of the most influential sorcerers of the previous generation. This connection reinforces the idea that the power and responsibility of jujutsu families continue across decades.
Similarly, Okkotsu Yuka’s background carries implied ties to the Zen’in lineage, a clan central to the original series’ political and power structure. Although these connections are not yet fully detailed, their presence suggests that elite bloodlines still shape the balance of sorcerer society in 2086. Through these family links, Modulo presents its new cast not as replacements, but as natural successors shaped by the legacy of earlier heroes and conflicts.
Lore Expansion Without Retcon
Beyond character lineage, Modulo carefully preserves the integrity of established canon. Official descriptions confirm that the arc takes place 68 years after the Culling Game, and those events are directly referenced within the story. Nothing in Modulo alters or contradicts the original timeline. Instead, the arc functions as a parallel future extension, exploring what the world becomes long after the original narrative has concluded.
Gege Akutami has explained that the concept behind Modulo was to examine a future or parallel timeline without rewriting history. This design ensures that past victories, tragedies, and character arcs remain untouched. The introduction of aliens, advanced technology, and new conflicts does not overwrite previous lore, but rather expands the scope of the universe into territory that the original series never reached.
By framing Modulo as a canonical future rather than an alternate reboot, the series achieves a careful balance. It honors the legacy of Jujutsu Kaisen while opening the door to new themes, larger-scale threats, and an entirely different stage for jujutsu sorcery to evolve.
Is Jujutsu Kaisen Modulo Canon?
Yes — Jujutsu Kaisen Modulo is fully canonical within the official Jujutsu Kaisen timeline. Both Shueisha and series creator Gege Akutami have confirmed that the arc takes place in the same universe as the original manga and continues the story 68 years after the Culling Game.
Although Modulo is labeled a “spin-off,” this classification refers only to its format and scope, not its continuity status. Unlike promotional side stories or alternate-universe specials, Modulo is written and supervised directly by Akutami and published as an official extension of the main series.
Importantly, the arc does not revise or contradict the original ending. Instead, it functions as a future-set continuation, expanding the world forward in time while preserving every major event, outcome, and character arc from the original narrative. In canon terms, Modulo represents the next historical chapter of the same universe rather than a parallel or non-official storyline.
Frequently Asked Questions (SEO Section)
As interest in the Modulo arc continues to grow, several recurring questions appear among readers. The answers below reflect only confirmed information from official publisher material and creator statements.
Is Modulo a sequel or a spin-off?
Modulo is officially classified as a spin-off, but functionally it behaves as a future sequel. It takes place decades after the original story and continues within the same canon, focusing on a new generation rather than the original cast.
How many chapters will Modulo have?
Gege Akutami has stated that the series is planned as a short serialization of approximately three volumes, which corresponds to roughly 21 chapters. As of early January 2026, 17 chapters have already been released, with weekly publication continuing toward the projected conclusion in spring 2026.
Does Modulo affect the original ending?

Are curses still the main enemy?
No. While cursed energy and jujutsu techniques still exist, the primary conflict in Modulo is no longer curse-driven. The central antagonistic force is the arrival of the Simurian alien race, shifting the focus toward interspecies tension and planetary-scale threats rather than traditional cursed spirits.
Will Modulo get an anime adaptation?
At this time, no anime adaptation has been announced. Because Modulo is a short, limited serialization, any future adaptation would depend on fan demand and production planning after the manga concludes. Until an official announcement is made, this remains purely speculative.
