World Overview
This world is a modern society layered over an invisible supernatural ecosystem shaped by Cursed Energy—negative emotions given form. Sorcery is a rare, dangerous craft practiced by a tiny fraction of humanity who can both perceive and manipulate curses. Technology is modern-day (smartphones, trains, global travel), but the “hidden world” operates through ancient traditions, clan politics, and secret organizations.
The core premise: human negativity births monsters, and sorcerers must confront a world that endlessly produces the very horrors they seek to end.

Geography & Nations
Most of the world is identical to real Earth, but several areas are significant hubs of Jujutsu activity:
Japan (Primary Setting)
Tokyo Jujutsu High – The strongest academy; frontline headquarters for modern sorcery.
Kyoto Jujutsu High – Traditionalist, politically conservative rival school.
The Cursed Wastelands – Abandoned districts, disaster zones, and spiritual scars where curses thrive unnaturally.
Clan Estates – Secluded compounds belonging to major bloodline families (Zen’in, Kamo, Gojo, etc.).
Global Sorcery
China, India, and Africa have their own sorcery traditions—often older and more diverse than Japan’s.
Europe contains ancient cults, rune-based sorcery, and relic hunters competing for powerful artifacts.
International groups rarely intervene unless Cursed Energy destabilizes borders or threatens mass casualties.
Races & Cultures
Humans: The vast majority, unable to perceive curses.
Sorcerers: A genetic minority born with the ability to sense, manipulate, or weaponize Cursed Energy. Organized into schools, clans, and occasionally independent mercenaries.
Cursed Spirits: Manifestations of human fear—ranging from minor nuisances to catastrophic, nation-threatening entities.
Cursed Objects: Remnants of overwhelmingly powerful sorcerers or spirits (e.g., Sukuna’s fingers).
Hybrid Beings: Half-cursed individuals, experiments, or special anomalies (like Choso-type Death Paintings).
Clans often hold cultural importance, with hierarchies, arranged roles, and deeply rooted traditions. (gojo clan, zenin clan, etc like jujutsu kaisen)
Current Conflicts
The Decline of Sorcerers: Sorcerers grow fewer each generation, making society vulnerable to massive spiritual disasters.
Clans vs. Modernization: Traditional families struggle to maintain authority amidst changing methods, independent sorcerers, and political reform.
Curse Evolution: Spirits are growing smarter and more organized, suggesting an unknown force accelerating their evolution.
Ideological War: Factions argue over the ethics of using curses as weapons, merging with them, or eliminating the system entirely.
This creates endless opportunities for missions, political intrigue, and large-scale crises.

Magic & Religion
Magic & Religion (JUJUTSU KAISEN)
Magic = Cursed Energy. It flows from negative emotions, trauma, purpose, or conviction.
Key systems:
Innate Techniques
Domain Expansions
Cursed Tools & Objects
Reverse Cursed Energy (healing)
There are no active gods, but powerful ancient sorcerers, vengeful spirits, and legendary curses are worshipped by cults as deities. Some cultures personify negativity as spiritual entities similar to demons or yokai.
Planar Influences
Material World – Normal reality.
Cursed Layer – A mirror-like spiritual ecosystem where curses move freely.
Most sorcery battles blur these layers. Domains temporarily overwrite the laws of reality, acting almost like pocket dimensions.
Certain places (tombs, temples, trauma sites) act as thin spaces where both worlds leak into one another.
Historical Ages
Age of Heian Sorcery – The peak era; insanely powerful sorcerers, constant war, catastrophic curses.
Age of Silence – Humanity suppressed knowledge of curses; sorcerers became hidden.
Modern Age – Technology rises, curses surge due to global stress and population density.
Post-Collapse Era (your campaign's era) – A new age defined by catastrophic anomaly rates and unstable Domain events.
Economy & Trade
The normal economy is unchanged, but in the hidden world:
Cursed Tools are forged, bought, and traded like weapons.
Black-market relic brokers deal in dangerous cursed objects.
Sorcerers often receive state stipends for exorcism missions.
Elite clans accumulate wealth through centuries-old holdings and spiritual “protection contracts.”
A covert network of couriers, informants, and fixers keeps the Jujutsu world functioning.
Law & Society
Justice is administered by:
The Jujutsu Higher-Ups – Secretive governing body deciding missions, punishments, executions, and political control.
Judges & Inquiry Sorcerers – Investigators who oversee sorcery-related crimes.
Society views sorcerers with a mixture of awe and fear (most citizens remain unaware of them).
Adventurer-type sorcerers are rare but often become folklore legends.
Punishments can be brutal: sealing, execution, forced missions, or imprisonment via cursed objects.
Monsters & Villains
Threats include:
High-Grade Curses born from collective human fears.
Cursed Users, criminals who weaponize curses intentionally.
Clans with extremist philosophies, seeking to “purify” humanity.
Ancient sorcerers revived or unsealed from past ages.
Experimental Hybrids, created from forbidden techniques or curse-manipulation projects.
Cult factions worshipping entities like Sukuna or other forgotten kings.
Villains in this world are rarely purely evil — many are ideological, tragic, or obsessed with breaking the existing system.
