The fate of humanity now rests in the hands of two jujutsu sorcerers – Yuka and Tsurugi Okkotsu, the grandchildren of legendary sorcerers Yuta Okkotsu and Maki Zenin.

The New Generation: Main Protagonists
1. Yuka Okkotsu – The Reckless Granddaughter
Yuka Okkotsu stands as one of Modulo’s central protagonists, inheriting not just the blood but also the fighting spirit of her grandparents, Yuta Okkotsu and Maki Zenin. Her character carries deep emotional complexity stemming from a precious ring that once belonged to her grandfather Yuta – a protective cursed object he personally entrusted to her before his death.
Character Traits & Abilities:
- Possesses significant cursed energy and matches the combat prowess reminiscent of Maki Zenin’s legendary fighting style
- Known for her reckless approach to combat situations, often rushing into danger without full consideration
- Generally maintains a calm demeanor but becomes easily agitated when her brother attempts to overshadow her achievements or take credit for her work
- Carries deep emotional weight from losing Yuta’s ring to her brother after their mother intervened
Background & Motivation: When Yuka was younger, her grandfather Yuta gave her his precious ring, explaining that he worried about her reckless nature and that the ring would protect her until she became a full-fledged jujutsu sorcerer. After Yuta’s death four years later, Yuka’s mother ordered her to surrender the ring to her brother Tsurugi, claiming it was a registered cursed object under the Gojo Clan and only Tsurugi was worthy of it. This betrayal fuels Yuka’s determination to grow stronger and eventually reclaim what she believes is rightfully hers.
2. Tsurugi Okkotsu – The Heavenly Restricted Heir
Tsurugi Okkotsu, at 17 years old, serves as a main protagonist in Jujutsu Kaisen Modulo. As the elder brother of Yuka and grandson of Maki Zenin and Yuta Okkotsu, he represents a unique paradox in the jujutsu world – born with a heavenly restrictive body that prevents him from possessing cursed energy.
Physical Description: Tsurugi appears as a teenage boy of average height with a slender yet distinctly muscular build. His spiky black hair dramatically juts outward toward the front, framing sharp, discerning gray eyes. His facial features bear a striking resemblance to members of the Zenin clan, particularly his grandmother Maki and cousin Megumi.
Abilities & Fighting Style:
- Like his grandmother Maki and the legendary Toji Fushiguro, Tsurugi has become an exceptional user of cursed tools despite lacking cursed energy
- Believes his strength without cursed energy makes him formidable enough to tackle any enemy
- Currently wears his grandfather’s ring around his neck, though he aims to prove he doesn’t need its protection
- Seeks to prove his worth to the Gojo Clan through his actions rather than inherited power
Uniform & Appearance: His Jujutsu High uniform consists of a brown, high-collared jacket with a full-zip closure and three-quarter length sleeves, paired with matching trousers. Underneath his jacket, Tsurugi’s torso and arms are heavily bandaged from intense training. He completes his attire with sandals.
3. Maru (Marulu Val Vol Yelvori) – The Alien Diplomat
Maru represents one of the most intriguing additions to the Jujutsu Kaisen universe – an extraterrestrial being from the Simurian race who possesses powers remarkably similar to jujutsu sorcery. His full name, Marulu Val Vol Yelvori, reflects his alien heritage while his shortened name “Maru” shows his attempt to integrate with human society.
Character Profile:
- Confirmed to be 19 years old according to Earth years, though his youthful appearance often causes confusion among his teammates
- Serves as an inspector sent by the Simurians to establish diplomatic relations and a potential home on Earth, permitted by Japanese authorities to oversee missions on the condition he doesn’t directly intervene
- Possesses a third eye that he can easily conceal to disguise himself as human, making him appear more human-like compared to other Simurians
Personality & Relationships:
- Despite hints that the Simurians might harbor less peaceful intentions, Maru genuinely means well and desires peaceful coexistence between humans and his species
- Has developed a fondness for human food, particularly takoyaki, which moved him to tears upon first tasting
- Maintains a strained relationship with his twin brother Cross, who views him as a clumsy bumbler and opposes his peaceful approach to humanity
- Forms a new generation trio with Yuka and Tsurugi, mirroring the dynamic of Yuji, Nobara, and Megumi from the original series
The Simurian Threat: Alien Antagonists
4. The Unnamed Simurian Leader
The mysterious leader of the Simurian race stands as potentially the most dangerous threat in Modulo. Though his name remains unknown, his presence alone has caused the Jujutsu Society to classify him as a Special Grade threat – placing him on the same danger level as Ryomen Sukuna from 68 years ago.
Threat Assessment:
- His introduction scene depicts him with a typical villain’s slouch, immediately establishing his menacing presence
- Physical appearance bears unsettling similarities to Sukuna, prompting fan theories about potential connections
- Commands the loyalty of approximately 50,000 Simurians aboard the mothership Naunax
- True motivations for coming to Earth remain shrouded in mystery
5. Jabaloma – The Political Strategist
Jabaloma serves as a subordinate to the Simurian Leader and acts primarily as a political diplomat attempting to broker deals between humans and aliens. His appearance draws immediate parallels to Master Tengen from the original series, suggesting potential deeper connections to the jujutsu world’s history.
Role & Characteristics:
- Functions as the diplomatic face of the Simurian invasion force
- Possesses physical characteristics remarkably similar to Lord Tengen, raising questions about ancient connections
- While potentially powerful, currently focuses on negotiation rather than combat
- Represents the political complexity of the human-alien conflict
6. Cross – The Hostile Twin
Cross stands as Maru’s younger twin brother and represents the aggressive faction within the Simurian ranks. Unlike his peace-seeking sibling, Cross harbors clear malice toward humanity and believes in fighting for his species’ survival through force rather than diplomacy.
Character Dynamics:
- Maintains polar opposite views from Maru – while Maru seeks peaceful coexistence, Cross is willing to fight humanity to ensure his species’ survival
- Views his brother as incompetent and naive for attempting peaceful relations
- Sets up a classic brother-versus-brother conflict that promises major story implications
- Represents the militant faction of Simurians who may not share their leadership’s diplomatic approach
Human Threats & Mystery Characters
7. The Human Trafficker (Unnamed)
This mysterious curse user represents a disturbing new threat in 2086 Japan – orchestrating the mass abduction of Curse Users to harvest their energy as a power source. His operations suggest a deeper, more sinister plot that extends beyond simple criminal activity.
Known Activities:
- Operates from a warehouse covered with talismans, using Kyoto’s grid-like infrastructure to enhance his cursed technique
- Was the first to inform Tsurugi about the alien invasion, revealing that the Jujutsu Inspector General had classified it as a special grade incident comparable to Sukuna’s attack
- Claims to be quitting the trafficking industry for reasons “only a jujutsu sorcerer would understand”
- Likely to play a major role as the series progresses, with true motivations yet to be revealed
8. Usami – The Mysterious Mentor
Usami’s introduction in Modulo marks the first actual appearance of a character previously only mentioned by Kusakabe in Chapter 253 of the original Jujutsu Kaisen series. Given the 68-year time gap, this may be a descendant or someone with unusual longevity.
Current Role:
- Serves as a mentor and guide to both Tsurugi and Yuka
- Officially confirmed Maru’s alien identity to the team, facilitating their formal partnership
- Appears surprisingly young despite the timeline, suggesting either unique circumstances or being a different person than the original Usami
- Holds significant authority within the current jujutsu society structure
9. Masayoshi/Masaki – The Child Curse User
Masayoshi emerged in Chapter 4 as a deeply disturbing new character – a 10-year-old curse user whose tragic backstory mirrors yet twists the classic Yuta-Rika dynamic. After losing his mother three years prior, his grief and loneliness transformed her spirit into a curse that now accompanies him.
The Dark Truth:
- Has been trapped in a cycle of repeating first grade at elementary school under different identities, with false families created by his mother’s curse
- The shocking revelation that Masayoshi buried his own mother with his bare hands adds a deeply disturbing psychological layer to his character
- Yuka’s investigation uncovered five corpses buried in his backyard, revealing the situation to be far more dangerous than initially suspected
- Represents a return to the horror elements that made early Jujutsu Kaisen so compelling
Supporting Cast & Future Implications
The Legacy of the Past
While Yuta Okkotsu and Maki Zenin have long since passed by 2086, their influence permeates every aspect of Modulo. Yuta lived to see his grandchildren but grew significantly weaker after Maki’s unexpected death, suggesting he may have died from grief. The original cast – Yuji Itadori, Megumi Fushiguro, Nobara Kugisaki, and others – are remembered as legendary heroes who defeated Sukuna, though none appear to have survived to the current timeline.
The Gojo Clan’s Continued Influence
The Gojo Clan remains active and influential in 2086, having controlled Yuta’s leadership position after his death. Their decision to transfer Yuta’s ring from Yuka to Tsurugi demonstrates their continued power in determining the fate of important cursed objects and their wielders. This political maneuvering suggests the clan politics that plagued the original series continue to shape the jujutsu world.
World-Building & Character Dynamics
The Simurian Integration Crisis
The arrival of approximately 50,000 Simurians above Nevada has created an unprecedented situation for Earth. These aliens possess cursed energy abilities similar to jujutsu sorcery but with different terminology and broader ethnic distribution of powers, contrasting with the primarily Japanese concentration of human sorcerers.
Evolution of Threats
The progression from cursed spirits to alien invaders represents a massive shift in the Jujutsu Kaisen universe. With the addition of the Simurians, an extraterrestrial race capable of wielding Cursed Energy, the series has elevated from Urban Fantasy to Science Fantasy, opening entirely new narrative possibilities.
Character Parallels & Contrasts
The New Trio vs. The Original:
- Yuka embodies Yuji’s determination but with Nobara’s fierce independence
- Tsurugi mirrors Megumi’s analytical nature combined with Maki’s physical prowess
- Maru brings an entirely new dynamic as an outsider trying to understand human culture
Sibling Rivalries: Both the Okkotsu siblings and the Simurian twins (Maru and Cross) represent conflicting ideologies:
- Yuka and Tsurugi compete for recognition and their grandfather’s legacy
- Maru and Cross embody the peaceful vs. militant approaches to the alien-human conflict
Power Systems & Abilities
Heavenly Restriction in the New Era
Tsurugi’s heavenly restriction follows the tradition established by Maki and Toji, proving that even 68 years later, those without cursed energy can stand among the strongest fighters through enhanced physical abilities and mastery of cursed tools.
Alien Cursed Energy
The Simurians’ ability to use cursed energy despite being aliens suggests that this power system extends beyond Earth, raising questions about the universal nature of cursed energy and its origins. Their different terminology and broader distribution of abilities among their population hints at alternative development paths for these powers.
The Ring of Yuta Okkotsu
This cursed object serves multiple narrative purposes:
- Symbol of the previous generation’s legacy
- Source of conflict between the Okkotsu siblings
- Potential key to future power developments
- Connection to Rika and the original series’ themes
Thematic Evolution
From Curses to Contact
Where the primary Jujutsu Kaisen manga dealt with internal human darkness manifesting as curses, Modulo explores external threats and the challenge of coexistence with alien life. The tone and mythos remain consistent with cursed energy and sorcery at the core, but the scope has expanded dramatically.
Generational Trauma & Legacy
The grandchildren of legendary sorcerers struggling with expectations and family politics reflects real-world themes of living up to family legacies while forging individual identities. Yuka’s loss of her grandfather’s ring to family politics and Tsurugi’s need to prove himself despite his restriction embody these struggles.
The Horror Returns
Masayoshi’s introduction in Chapter 4 marks a return to Jujutsu Kaisen’s horror roots, with the revelation of multiple buried corpses and a child clinging to his dead mother’s ghost creating a genuinely disturbing narrative that recalls the series’ earliest and most effective scares.
Future Developments & Speculation
Confirmed Story Elements
According to Gege Akutami, Modulo is planned as a concise series running for approximately six months and comprising roughly three volumes. This condensed format suggests a focused narrative with rapid plot development and minimal filler content.

Conclusion: A New Chapter in Cursed History
Jujutsu Kaisen Modulo has proven in just a few chapters that Gege Akutami’s skills as a writer have significantly evolved since beginning the original series. From its focus on character-driven storytelling to its clear narrative goals, Modulo addresses many criticisms of the original while maintaining the core elements that made Jujutsu Kaisen beloved.
The character roster of Modulo brilliantly balances nostalgia with innovation. While honoring the legacy of Yuta, Maki, and the original cast through their descendants, it introduces wholly original concepts like the Simurians that push the franchise in exciting new directions. Each character, from the determined Yuka to the mysterious Masayoshi, adds layers to an increasingly complex narrative that promises to expand the Jujutsu Kaisen universe in ways fans never expected.
As we await future chapters, the nine major characters introduced so far have established a strong foundation for what promises to be a worthy successor to one of modern manga’s most successful series. Whether dealing with alien diplomacy, human trafficking, or haunted children, Modulo proves that the world of cursed energy still has many stories to tell.
With approximately 50,000 Simurians hovering above Earth and tensions rising between peaceful and militant factions on both sides, the stage is set for conflicts that will test this new generation of sorcerers in ways their grandparents never faced. The question isn’t whether Yuka and Tsurugi can live up to their legendary heritage – it’s whether they can surpass it while facing threats that blur the line between science fiction and supernatural horror.
