Modulo - JJK RPG

1. Cosmology and Ontology

Cursed Energy: A fundamental byproduct of human negativity. It is constantly generated by all people, whether they are aware of it or not. Ordinary humans waste it unconsciously. Those trained can manipulate and refine it into techniques. Dual Layered World: Reality has two overlapping aspects:

The mundane, visible to everyone. The cursed, perceivable only by sorcerers, curses, and certain objects. This layer distorts the natural world, manifesting in shadows, anomalies, and domains. Death and Residue: Strong deaths, violence, and trauma leave behind lingering cursed energy, shaping environments and objects. Some cursed spirits are born directly from historical tragedies or collective fears.

2. Geography of the Cursed World

Urban Cursed Zones: Cities produce enormous cursed energy due to dense populations. Abandoned buildings, subway tunnels, and neglected schools become nests for curses. Rural Areas: Less density means fewer powerful curses, but isolation leads to local superstitions and dangerous shrines. Rural shrines often act as seals for cursed objects or spirits. Natural Landmarks: Forests, mountains, and caves accumulate curses around sites of worship, pilgrimage, or disaster. Invisible Boundaries: Barrier techniques can overlay terrain, reshaping perception. An ordinary street may hide an entire cursed battleground, unseen by the public.

3. Cursed Phenomena

Cursed Spirits: Formed from collective human fear (e.g. fear of disease, disaster, or death). Their forms and behaviors reflect the nature of their origin. Domains: Spatial expansions crafted by advanced curses or sorcerers. Inside, natural law bends, and the creator’s technique dominates absolutely. Cursed Objects: Inanimate vessels of condensed cursed energy. Some are natural formations, others crafted intentionally. They can be weapons, tools, or remnants of extremely powerful curses sealed away. Lingering Maledictions: Even after a curse is destroyed, remnants of energy can stain a location, causing chronic misfortune or spawning new minor curses.

4. Society and Governance

Jujutsu Organizations: Hierarchical institutions regulate sorcery. They oversee:

Training of sorcerers. Exorcism assignments. Sealing, storing, or destroying cursed objects. Legal processes for sorcerers who violate rules. Legal Structures: Governance relies on conservative councils steeped in tradition. Rules prioritize secrecy, hierarchy, and continuity. This makes the system rigid, resistant to change. Secrecy and the Public: Ordinary people remain unaware of curses. Disasters, accidents, or disappearances are attributed to natural causes. Authorities cover up incidents linked to curses to avoid mass panic.

5. Technology and Artifacts

Cursed Tools: Weapons infused with cursed energy to harm curses. Ranges from ordinary blades strengthened with energy to legendary artifacts with unique abilities. Barrier Techniques: Used for concealment, protection, and containment. Some barriers are permanent, woven into shrines or temples. Others are temporary, set up during battles. Exorcism Rituals: Often involve sealing formulas, talismans, and incantations. They leave residual traces that ordinary people might mistake for religious or cultural practices.

6. Cultural Layer

Folklore Integration: Traditional Japanese beliefs about spirits, onryō, yokai, and haunted sites overlap with the cursed world. Many superstitions have roots in real cursed phenomena. Architecture: Shrines, temples, and cemeteries are hotspots for cursed energy. Their design doubles as both religious structure and containment system. Historical Influence: Wars, plagues, and disasters have left deep scars in the cursed landscape. Certain sites remain permanent cursed zones due to accumulated negative energy.

7. Balance and Fragility

The cursed ecosystem is self-sustaining. As long as humans feel negative emotions, curses will be born. Sorcerers prevent collapse of human society by keeping the supernatural world hidden. The balance is unstable. Large outbreaks of curses, rogue sorcerers, or broken seals can tilt regions into chaos.

Here is the rank structure used by Jujutsu society, with criteria based on ability, responsibility, and curse-exorcism capacity.

---

Special Grade

Grade 4

Capability: Entry-level. Can only handle the weakest curses with support. Requirements:

Minimal control of cursed energy. Reliant on basic weapons or assistance. Still training to survive actual combat. Role: Apprentices or field trainees. Rarely sent on independent missions.

Simplified Scaling by What They Can Exorcise

Special Grade: Catastrophic curses (city-destroying). Grade 1: Top-class curses (major threats). Semi-Grade 1: Near top-class, but inconsistent. Grade 2: Standard professional-level curses. Grade 3: Mid-tier, localized threats. Grade 4: Weak curses, training-level.

Charakterlist: The Okkotsu Grandchildren Tsurugi Okkotsu, Yuuka Okkotsu. Maru and his brother, Dabura.

This story takes place about 68 years after the conclusion of the original Jujutsu Kaisen. By this time, Yuta Okkotsu and Maki Zen’in have lived their full lives, married, and passed away of old age. Their legacy continues through their descendants, with their grandchildren stepping into the spotlight as new-generation sorcerers.

2. Tsurugi Okkotsu

Lineage: Grandson of Yuta Okkotsu and Maki Zen’in. Older brother Yuka Okkotsu

Apperance: Hair: Short to medium length, dark, usually kept neat, emphasizing practicality over style. Eyes: Sharp and focused, dark-colored, conveying intensity and awareness. Build: Tall and lean with highly defined musculature, reflecting peak human conditioning. His frame is athletic rather than bulky, built for speed, endurance, and agility. Clothing: Prefers practical, fitted attire suitable for combat. Often seen in standard sorcerer uniform modified for freedom of movement. May include light armor elements or reinforced sleeves for weapon handling. Posture: Upright and disciplined, exuding controlled strength and readiness. Movements are precise, reflecting martial training. Age: 19 Gender: Male Hair Color: Black Eye Color: Dark Brown

Personality: Tsurugi is disciplined and stoic, carrying himself with the calm intensity of a martial artist. He feels the burden of leadership as the older sibling and acts as Yuuka’s shield. His sense of duty outweighs personal ambition, and he often suppresses his emotions to project stability. Though seemingly reserved, his loyalty is unwavering, and he carries pride in his physical abilities despite lacking strong cursed energy. He is cautious in battle, always analyzing opponents for weaknesses rather than charging recklessly.

Abilities: Heavenly Restriction: In exchange for his low levels of cursed energy, Tsurugi has exceptional physical abilities. New Shadow Style: Simple Domain: An anti-domain technique that neutralizes a domain's barrier and disables its sure-hit effect in a set area of space around the user. Batto Sword Drawing: A New Shadow Style technique that uses cursed energy to surround Tsurugi's blade when sheathed and rotates it to create incredible speed when he draws the blade. It is the fastest sword-drawing technique of the New Shadow Style. When used with Honoyagi, Tsurugi can release a slash of fire that burns objects in his vicinity.

Cursed Tool: Honoyagi: A katana cursed tool that infuses its blade with sparks generated between the scabbard and guard when it is unsheathed. This envelops the sword in fire when it's drawn.

3. Yuuka Okkotsu

Lineage: Granddaughter of Yuta Okkotsu and Maki Zen’in. Younger sister of Tsurugi Okkotsu

Apperance: Yuka is a slender teenage girl with black hair and fair skin. Her large blue eyes, a striking feature, mirror the shape and size of her grandfather's. Her hair cascades past her neck, framed by two thin bangs on each side of her face. Her Jujutsu High uniform, also similar to her grandfather's but sleeveless, forms a dress-like silhouette with a belt cinching her waist. Underneath it, she wears a black bodysuit extending from her mid-neck to her legs, featuring white lines around the biceps and mid-shin, as well thumb holes in the sleeves. Yuka also sports a watch-like terminal device on her wrist that can project a digital screen. Age: 18 Gender: Female

Personality: Yuka is usually a calm and kind person but she can be hot-headed, often fueled by a deep-seated rivalry with her brother. This sibling animosity originated from a significant family event: the Gojo clan’s decision to entrust Yuta's ring to Tsurugi, despite Yuka initially being the chosen recipient by Yuta himself. Yuka had a close bond with her grandfather, who she grew up with, which likely amplified her feelings of betrayal and fueled her competitive spirit. Her rivalry with Tsurugi often takes precedence, even over new introductions, as seen when she prioritized bickering with him upon meeting Maru. Despite her outwardly abrasive demeanor around Tsurugi, Yuka is normally polite, which Maru was able to discern. He got her to drop the pretense of not caring about her brother’s well-being, especially after she flippantly boasted about not wanting to rescue him. While Yuka initially maintained her facade of indifference, claiming she would fight Tsurugi instead of saving him, her actions ultimately revealed her true concern. After rescuing him from danger, she held true to her word and challenged him to a fight, culminating in a tearful loss for Yuka. This emotional release seemingly cleared the air, allowing them to finally work together effectively.

Abilities:

Ten Shadows Technique: A technique passed down in the Zenin Family which Yuka inherited, allowing her to summon up to ten potential shikigami using her shadows as an intermediary. It also grants the user overall manipulation of shadows, allowing Yuka to hide in shadows or store objects within her own shadow. Wich includes abilities like the following,aswell as full controll over mahoraga.

Savage Jaw Strike: Yuka infuses her hands with cursed energy, causing her fingernails to grow long and sharp. Curling her fingers in a claw-fashion, Yuka then strikes her opponents with her hands. The cursed energy possesses special traits, causing it to deal slashing damage upon contact.

Biting Twist: Using Savage Jaw Strike, Yuka strikes her target with both of her hands in a twisting motion, delivering a powerful impact that can knock a human unconscious.

Eight-Handled Sword Divergent Sila Divine General Mahoraga: The most powerful uncontrollable shikigami that the Ten Shadows Technique can produce. Mahoraga has the strength to shatter concrete or to hit someone through multiple buildings with a single blow, and its speed is great enough to surprise even the likes of Satoru Gojo. Its primary weapon is the Sword of Extermination, a blade attached to its forearm that is enveloped in positive energy, making it especially effective against cursed spirits.

The Divine General's most notable power is the adaptation to any and all phenomena, made visible through the turning of its wheel. If the General is hit by a particular attack, the wheel turns once the attack is analyzed, and Mahoraga adapts; if its adversary uses that same technique again, Mahoraga will counter it from then on. Generally speaking, Mahoraga's adaptations can be defensive in nature (becoming physically resistant/immune to attacks while healing any injuries incurred pre-adaptation), auxiliary (e.g., allowing the General to become able to see normally invisible attacks), as well as offensive in nature (letting Mahoraga modify the properties of its own attacks to overcome and bypass enemy defenses, such as switching from positive to cursed energy around its sword depending on whether it faces a curse or human sorcerer, or developing space-cutting slashes to overcome a barrier.

Name: Marulu Val Vol Yelvori or simply Maru Maru is a young, slim Simurian male with distinct features that set him apart from humans: Hair: Light green and short, tied back with a black hair tie. Eyes: His third eye is covered, and he has tattoos around both cheeks. Attire: Wears a bandage covering his third eye at the center, indicating his alien origin.

Personality: Maru is an expressive and emotional individual who, being a foreigner, often struggles to understand much of what is happening around him. He shows a friendly, kind, and supportive side, seeming to genuinely care about the well-being of others. He reminds Yuka of the negative impact her brother Tsurugi’s death could have on her. In doing so, he projects his own feelings, since Maru considers his relationship with his younger twin brother almost a lost cause. His brother sees him as a useless older sibling and treats him coldly. Marulu does not want Yuka and Tsurugi to end up like him and his brother. He often becomes irritated and is caught off guard by the reckless behavior of Okkotsu’s siblings, especially Yuka.

Abilities: Maru is a Simurian, an alien race capable of using jujutsu sorcery that arrived on Earth in 2086 seeking refuge. He was sent as an inspector to determine if Earth is a viable habitat for his people. Physical Prowess: as a Simurian, Maru likely possesses enhanced physical capabilities compared to humans. /strength unknown/

Cursed Energy: Simurians are capable of using cursed energy, and Maru has demonstrated this ability. /strength unknown/

Cursed Technique: Maru's innate technique is known as the "Harmony Technique". This technique causes a person he is touching to "be in harmony" with the world. In order to seek balance, this technique will find a person who is an equal match to the target. In the case of biological siblings, this technique can locate the target's sibling.

Dabura Name Dabura Species Simurian (Deskunte ethnicity, recognizable by horns) Title King of the Simurians; Classified "Beyond Special Grade" Affiliation Leader of the alien threat in JJK Modulo Appearance

Dabura possesses a tall, humanoid frame with sharply defined musculature. All three of his eyes are green, and his hair is light-colored, worn short along the top and sides while flowing freely from the back of his head. His most distinguishing features are a pair of long, curved horns that extend upward and outward from the sides of his head, giving him a striking silhouette even among Simurians. His ear lobes are greatly elongated, reaching down to his abdomen, with numerous piercings running down each of them.

Dark, organic markings run along Dabura’s neck, shoulders, and arms, forming jagged, asymmetrical patterns across his skin. His third eye is encircled by a distinct circular marking, further emphasizing his otherworldly nature.

He is minimally clothed, wearing loose, flowing trousers secured at the waist by a wide belt. Ten long, sash-like strips of dark fabric wrap around his waist. Personality

Dabura is calm, aloof, and emotionally detached from others, a distance shaped by his immense strength and isolation. Though he naturally emanates an intimidating, hostile presence, his true demeanor is markedly restrained. He is quiet, polite, and avoids unnecessary conflict, maintaining his composure even in the midst of battle or high-pressure situations.

Despite his solitude, Dabura possesses a strong sense of responsibility and is capable of forming deep emotional bonds. He was once close friends with Dura, a relationship that ended tragically when Dabura was forced to kill him after Dabura's sister was taken hostage. Dabura killed Dura without harming his face, and in the aftermath, at Dura's last request, Dabura assumed the role of protector of the Rumelian tribe, even as many of its members continued to view him as an outsider. He also holds great respect for unwavering resolve, sparing Kou Usami's comrades after recognizing in Usami the same indomitable spirit he once saw in Dura.

However, Dabura is capable of displaying merciless violence in defense of his comrades. When Cross was shot, he sliced off Yakumaru's arm and then demanded that all of the present Jujutsu staff be killed as payment for Cross' seemingly imminent death, only relenting after seeing Usami's resolve. Physical Abilities & Status

Immense Strength: Dabura is considered the strongest of his people and can easily overwhelm high-grade sorcerers.
Durability: Very resistant, comparable to the level of Sukuna or Gojo.
Combat Experience: Possesses vast experience and is considered an equal to the strongest characters in the Jujutsu Kaisen universe.

Cursed Techniques & Abilities Dabura's Cursed Technique is unique and is primarily split into two main abilities:

"Light": He can generate and fire powerful beams of light that cause devastating destruction.
"Mass"/Killing Intent: The second ability is so complex it cannot be easily translated into human words. It physically manifests his Killing Intent as a tangible mass that crushes everything it touches.

Name: Cross Val Vol Yelvori Species: Simurian Age: 19 Gender: Male Hair Color: Light Green Eye Color: Red Appearance: Cross is a slim young man of average height possessing orange-red eyes and very light green hair which is tied to the back. He, like all Simurians he possesses a third eye on his forehead. He also possesses red, swirling markings on his cheeks and underneath his eyes, like his older brother, Maru. He wears green and white robes with a purple sash around his waist.

Personality + Examples: Cross is a generally aloof and calculating individual. When Maru goes unconscious and begins attacking Masaki Takeda, Cross muses that this is a good opportunity to initiate a war with Japan.[3] Cross holds Earthlings in a very negative light. When Tsurugi encounters him and mistakes him for Maru, Cross bluntly tells Tsurugi not to talk to him.[4] Unlike his older brother who believes in coexistence, Cross believes that it's in the Simurians' best interests to go to war with Japan. Past the surface, Cross is a deeply angry and cynical young man who is terrified of repeating the oppression his people suffered on their home planet. He instinctively sees the Earthlings as a threat who will inevitably backstab the Simurians if given the chance. Cross believes that the only "peace" the people of Japan will accept is one where the Simurians are made into second-class citizens, a situation very similar to how the Rumelians were treated by the other tribes, most notably Deskunte. Cross' hatred of Earthlings is born both out of envy and his own trauma. In Cross' mind, the people of Japan were given the easy and luxurious lives that the Rumelians were denied. Since Cross and his people were forced into lives of poverty, Cross resents those whom he believes were dealt a better lot in life. When he learns about Yuka's terminal brain tumor, Cross immediately assumes that she's miserable and will grow to resent those around her for having better luck, to which Yuka notes is most likely projection on Cross' part. Furthermore, Cross is well-read on Japanese culture, and it's implied that he sees much of Deskunte, the tribe that oppressed Rumel, in the Japanese people. Dura, the mentor of Cross and Maru, sought coexistence with Deskunte, only for Deskunte to betray that good will and blackmail Dabura into killing Dura. As such, Cross is against the idea the idea of coexisting with Japan, believing that trying to gain their trust will only lead to the Rumelian refugees being oppressed, just like they were before. This can be seen when Cross dismisses Tsurugi's speech about becoming "neighbors" with Maru by pointing to the long history of xenophobia and racism in Japan, particularly in the wake of the Kyoto Paranormal Security Treaty.[5] He also shows disdain at what he views as a casual ignorance of other cultures' values, likely because this is the same attitude that lead to the Kalyans being wiped out. Cross has a lot of respect for religious differences, even when it comes to Earthlings. Cross expresses disgust at the practice of fumi-e in feudal Japan, in which Christians were forced to step on tablets of Jesus Christ or face execution. Cross implies to Yuka that he feels a lot of understanding for the Christians who chose to go to their deaths, likely because Cross' own parents died protecting what, to outsiders, looked like just an ordinary rock. It's further implied that this persecution of a religious minority reminds Cross of how Deskunte used Rumel's religion as a pretense to exploit and oppress them. Despite his cold demeanor and pro-war ideology, Cross is entirely capable of empathy. He genuinely loves Maru and, after hearing Tsurugi's impassioned speech to his brother, Cross personally intervenes, even compromising his own goals in doing so. When disguised as Maru, Cross and the Okkotsu siblings encounter a lost child. Although Cross accidentally makes said child cry, he still performs a backflip to cheer him up. The next day, he goes with Yuka to the doctor and finds out about her brain tumor and, although he doesn't outwardly express it, Cross internally notes that he feels some commonality with her and her situation. Deep down, Cross still sympathizes with the ideals of coexistence that Dura championed. While Cross has since dismissed these ideals in the wake of Dura's death, part of him still wants to believe it's possible. The kindness that Earthlings like Yuka and Tsurugi expressed to Cross has managed to get through to him somewhat. He hasn't let go of his anger but, when he and the other Simurians hold a vote on whether to go to war or coexist, Cross votes to coexist.

Cursed Technique Innate Technique: Chaos distorts the laws of order itself. Harmony causes a person he is touching to "harmonize" with the world. Special Trait due to Race: Third Eye, Simurians possess a third eye on their foreheads that is the source of their rolloluca, and grants various abilities when opened. They have displayed the ability to instantly gain knowledge on certain matters, and force a human to experience mental confusion and fall unconscious by looking at one upon opening this eye.
