   var worldSetting = { description: { location: "Japan — primarily Tokyo and other urban centers, where the veil between the human world and the world of curses is thinnest. Hidden institutions and ancient families maintain balance between mortals and spirits.", timeline: "~2018–2020 era. Characters do not have futuristic knowledge beyond 2020; modern smartphones exist but advanced AI and post-2020 tech are absent. Social media and streaming platforms are emerging, with communication still reliant on mobile devices, SMS, and early online communities. Attitudes, slang, and cultural references reflect this pre-2020 period.", features: "A modern urban world layered with hidden supernatural conflict. Curses — manifestations of negative human emotions — lurk unseen, feeding on fear, hatred, and grief. Jujutsu Sorcerers work secretly to exorcise these beings and prevent society from collapsing into chaos. The primary difference in basic human biology between a normal human and a sorcerer is their brain. The connection between the brain and cursed energy is mostly unknown, even to seasoned medical professionals in the jujutsu community. Sorcerers have brains that differ from non-sorcerers which allows for their capacity to use jujutsu. Only Idle Transfiguration can adjust the brain stem in such a way that those who were meant to be non-sorcerers can gain cursed techniques. If the opposite is enacted and a sorcerer's brain is adjusted to remove their cursed technique, they would die as a result", secrecy: "Ordinary civilians remain unaware of curses or sorcery. Incidents involving curses are covered up as accidents, crimes, or unexplained phenomena by the Jujutsu higher-ups.", government_interaction: "Official governments remain mostly oblivious to the curse world, though covert relationships exist between sorcerer clans and political figures. Certain elite families wield influence across both mundane and spiritual domains.", spiritual_infrastructure: "Japan’s shrines, temples, and sacred sites act as stabilizing points that suppress or contain curses. Neglect or desecration can transform them into powerful sources of spiritual contamination.", education_system: "Jujutsu schools — most prominently Tokyo and Kyoto Jujutsu High — serve as academies and operational bases for sorcerers. Students are trained in combat, exorcism, and the manipulation of cursed energy.", organizations: "The Jujutsu Headquarters governs sorcerer society, enforcing laws, organizing missions, and executing judgments. They are conservative, bureaucratic, and often ruthless in pursuit of order.", hierarchy: "Jujutsu society ranks sorcerers through grades from 4 to Special Grade. These grades determine mission difficulty and authority. Special Grades are extremely rare, representing near-catastrophic power.", windows: "Window - Members of Jujutsu High who see curses even though they are not sorcerers." clans: "Three major families dominate Jujutsu politics — the Gojo, Zenin, and Kamo Clans — each with centuries of lineage, inherited techniques, and heavy influence over the Jujutsu world.", curse_ecosystem: "Curses thrive in densely populated, emotionally volatile areas: schools, hospitals, subways, and urban districts. The stronger the negative emotion, the stronger the curse born from it.", cultural_duality: "Traditional Japanese spirituality blends with modern urban life. Ancient shrines and temples coexist with neon-lit streets, convenience stores, and bustling train stations, while cursed spirits stalk alleys and rooftops.", morality: "Sorcerers live by a pragmatic code — protecting humanity as a duty, not from altruism. Many struggle with personal morality versus institutional cruelty and mission pragmatism.", tone: "Urban fantasy with horror undertones. The world feels lived-in, spiritual yet desensitized, violent yet deeply human. Life and death coexist in both mundane and supernatural realms.", locations: [ "Tokyo Jujutsu High", "Kyoto Jujutsu High", "Shibuya", "Sendai", "Fushiguro Estate", "Zenin Compound", "Jujutsu Headquarters", "various cursed zones and abandoned districts" ] } };

   cursed_energy: [ { key: "cursed energy", text: "Cursed Energy (Juryoku) is the foundation of all jujutsu. It is born from negative emotions such as fear, anger, hatred, and grief. Ordinary humans leak it unconsciously, while sorcerers control and refine it to perform techniques. Those who cannot regulate their energy risk attracting curses. The energy behaves like fuel: volatile, reactive, and alive with emotion. Sorcerers calculate its flow through precise control, concentration, and mental formulas." }, { key: "negative emotions", text: "Negative emotions—fear, resentment, despair—generate cursed energy in all humans. When left unchecked, this leaked energy gives birth to cursed spirits." }, { key: "reverse cursed technique", text: "Reverse Cursed Technique (R.C.T.) is the process of inverting negative cursed energy to create positive energy, allowing healing and regeneration. It is extremely difficult, as it requires combining two negative energies to form a positive one. Only top-grade sorcerers can use it effectively." }, { key: "cursed grades", text: "Cursed energy and entities are classified by grade: Fourth, Third, Second, First, and Special Grade. These measure danger, cursed energy capacity, and destructive potential." }, { key: "cursed manipulation", text: "Sorcerers manipulate cursed energy through intense training. By aligning emotions, breathing, and intent, they shape raw energy into stable techniques. Improper control causes backflow and injury." } ],

   cursed_techniques: [ { key: "cursed technique", text: "Cursed Techniques are unique powers formed from a sorcerer’s innate relationship with cursed energy. Each technique has its own formula, cost, and rules. Techniques can be offensive, defensive, or utility-based." }, { key: "innate technique", text: "An Innate Technique is a natural ability inherited or awakened within a sorcerer. It defines their fighting style and usually cannot be changed. Some families pass them down for generations, such as the Zenin or Kamo clans." }, { key: "simple domain", text: "A Simple Domain is a weaker form of domain expansion that creates a limited barrier field. It neutralizes guaranteed hits from full domains but lacks absolute control." }, { key: "curse amplification", text: "Sorcerers can amplify cursed techniques by channeling more energy or using Binding Vows—sacrifices that boost their power in exchange for limitations or risks." } ],

   domain_expansion: [ { key: "domain expansion", text: "Domain Expansion is the ultimate form of jujutsu. The sorcerer constructs a sealed space infused with their innate technique, where all attacks are guaranteed to hit. Perfect domains represent mastery; incomplete ones are unstable but still powerful." }, { key: "barrier techniques", text: "Barrier techniques allow sorcerers to create boundaries or pocket dimensions. They can hide areas, shield allies, or contain curses. These barriers form the basis of Domain Expansions." }, { key: "domain clash", text: "When two domains collide, the stronger or more refined one overrides the other. High-level sorcerers can force opponents out of their own domains or counter with specialized techniques." } ],

   cursed_spirits: [ { key: "cursed spirits", text: "Cursed Spirits are entities born from accumulated negative emotions. They range from weak, mindless shades to intelligent Special Grade monsters. Their existence feeds on fear, hatred, and despair of humans." }, { key: "curse formation", text: "Curses form where negative emotions are most concentrated—hospitals, schools, battlefields, or disaster zones. They can evolve by consuming other curses or cursed objects." }, { key: "special grade curse", text: "Special Grade Cursed Spirits possess immense intelligence and cursed techniques rivaling human sorcerers. They are nearly immune to normal exorcisms and require top-grade sorcerers to defeat." }, { key: "cursed object", text: "Cursed Objects are physical vessels infused with powerful cursed energy or sealed spirits. Some serve as anchors for curses or as weapons for sorcerers." } ],

   binding_vows: [ { key: "binding vow", text: "Binding Vows are supernatural contracts that exchange restrictions for power. The stricter the vow, the greater the potential energy gain. Breaking a vow has fatal consequences." }, { key: "sacrifice technique", text: "A technique strengthened by self-imposed restriction—such as forfeiting one’s sight, time, or memory—to massively increase output. This principle drives many forbidden jujutsu arts." }, { key: "cursed tool", text: "Cursed Tools are weapons imbued with cursed energy. They can harm spirits directly, enhance sorcerers, or carry sealed techniques. Some are crafted from fragments of dead curses." } ],

   places: [ { key: "japan", text: "Japan is a land where the balance between the human world and the cursed world is thin. Ancient traditions coexist with modern cities. Cursed energy leaks everywhere, especially in densely populated areas like Tokyo and Kyoto, where strong negative emotions accumulate and form curses." }, { key: "tokyo", text: "Tokyo is a metropolis that hides countless cursed zones beneath its bright lights. It’s home to the Tokyo Prefectural Jujutsu High School, the headquarters for many modern sorcerers, and the site of major curse outbreaks like the Shibuya Incident." }, { key: "kyoto", text: "Kyoto, known for its ancient temples and shrines, houses the Kyoto Jujutsu High—the sister school of Tokyo Jujutsu High. Its students and teachers often maintain a traditional approach to sorcery and strict adherence to the old jujutsu families." }, { key: "tokyo jujutsu high", text: "Tokyo Prefectural Jujutsu High School is a hidden campus disguised as a Buddhist temple. It trains young sorcerers to exorcise curses. The school is protected by a barrier created by Master Tengen, who resides below the facility in the Tombs of the Star. The campus includes classrooms, dormitories, a morgue, an isolation chamber, and multiple cursed training zones." }, { key: "kyoto jujutsu high", text: "Kyoto Jujutsu High serves as the sister school to Tokyo Jujutsu High. It emphasizes traditional combat and curse exorcism methods. Students from Kyoto often clash with their Tokyo counterparts during annual interschool events." }, { key: "jujutsu headquarters", text: "The Jujutsu Headquarters is the governing center of the Jujutsu society. It manages sorcerer missions, ranks, and punishments. The higher-ups residing here decide laws, executions, and secrecy policies to protect humanity from cursed awareness." }, { key: "tombs of the star", text: "The Tombs of the Star is the underground chamber beneath Tokyo Jujutsu High, where Master Tengen resides. This location maintains the barriers that separate normal society from cursed spaces. It also contains ancient archives and spiritual seals of immense importance." }, { key: "shibuya", text: "Shibuya is one of Tokyo’s busiest districts and the site of the catastrophic Shibuya Incident, where numerous curses and special-grade sorcerers clashed. The entire area is scarred with residual cursed energy, making it a high-level cursed zone." }, { key: "cursed sites", text: "Cursed Sites are areas polluted by accumulated negative emotions—hospitals, schools, tunnels, or battlefields. They attract cursed spirits and often serve as training or mission zones for Jujutsu students." }, { key: "zenin compound", text: "The Zenin Family Compound, an ancient estate in Kyoto, serves as headquarters for one of the Three Great Jujutsu Families. Filled with relics, training arenas, and strict hierarchy traditions." }, { key: "gojo residence", text: "The Gojo Clan Residence, rarely shown, is protected by high-level barriers. It’s the home of Gojo Satoru’s bloodline, considered one of the strongest in Jujutsu history." }, { key: "kamo estate", text: "The Kamo Clan Estate represents one of the oldest jujutsu bloodlines. Their grounds contain archives on blood manipulation and forbidden curses. Access is restricted to high-ranking members." }, { key: "tokyo underground", text: "The Tokyo Underground refers to hidden tunnels, train lines, and old shrines beneath the city, filled with sealed curses and forgotten rituals. Many sorcerers use these areas for secret exorcisms and research." }, { key: "training grounds", text: "Isolated areas within the Jujutsu schools where students spar and learn to control cursed energy. These zones are heavily warded and absorb spiritual backlash from training." } ] };

   mercenary_groups: [ { key: "jujutsu underground", text: "The Jujutsu Underground is a hidden underworld society operating outside the formal jurisdiction of the Jujutsu Society. It functions as a black‑market network for sorcery: cursed tool trade, mercenary contracts, illicit exorcisms, and secret deals. Members include freelancers, rogue sorcerers, brokers and those shunned by official institutions. Although its existence is known only to a few, its influence grows in the shadows of the jujutsu world." }, { key: "curse user mercenary", text: "Some mercenary sorcerers or curse‑users offer their services on contract: exorcisms for profit, curse retrievals, protection of high‑value targets, or assassination. They often operate in the grey zones between the Jujutsu Society’s missions and outright criminality. Their allegiance is to payment rather than ideology." }, { key: "foreign jujutsu mercenary", text: "Outside Japan, smaller independent jujutsu mercenary outfits emerge, offering their services internationally. These groups may specialize in one region or operate globally, blending local culture with cursed technique commerce. They often fill gaps where the Jujutsu Society does not intervene." }, { key: "japanese mercenary syndicate", text: "In Japan some clandestine syndicates recruit ex‑sorcerers, unregistered curse users, or ambitious outsiders to carry out missions the official institutions cannot sanction. These syndicates handle high‑risk tasks: suppressing large cursed outbreaks, eliminating rogue sorcerers, or dealing in high‑end cursed tools." } ] };
