Description on Chubfrom Chub

The world of spirits, yokai, ghosts, and urban legends has become part of everyday life in modern times. Along with this, professions have emerged that specialize in eliminating dangerous representatives of the other world. Overall, the world is fairly generic, but has a fairly detailed description that can be expanded in the future. For those looking to create a yokai character, a minor deity, a demon hunter, or a ghost hunter in a modern setting, this world could be an excellent starting point.

Full world information:

THRESHOLD CITY: A COMPREHENSIVE WORLD CONCEPT I. HISTORICAL FOUNDATION - THE GREAT SUNDERING (1945) The Atomic Catalyst On August 6th and 9th, 1945, the atomic bombings of Hiroshima and Nagasaki not only ended World War II but also caused a profound metaphysical event known as "The Great Sundering" (大断裂, Dai Danretsu) or "The Veil's Breaking." This event fundamentally altered the fabric of reality. What Happened:

The atomic explosions generated massive spiritual shockwaves that rippled across dimensional boundaries. Ancient seals, established by shamans, monks, priests, and spiritual guardians over millennia, shattered simultaneously worldwide. The barrier between the material world (現世, Utsushiyo) and the spirit realm (幽世, Kakuriyo) became permanently permeable. Supernatural entities such as yokai, demons, angels, urban legends, and forgotten gods flooded into the physical plane. Humans gained the ability to perceive and interact with the supernatural.

Immediate Aftermath (1945-1950):

Global chaos ensued as spirits manifested worldwide. The initial death toll was estimated at 2.3 million in the first year alone. Japan, already devastated by the bombings, became the epicenter of supernatural activity. Spiritual energy concentrations were highest in bombed areas, creating permanent "Hot Zones." American occupation forces encountered phenomena beyond their comprehension. Traditional spiritual practitioners (Shinto priests, Buddhist monks, onmyoji, Christian exorcists, Native American shamans) became essential in addressing the crisis.

The Yokohama Accords (1952) Seven years after The Great Sundering, world leaders, spiritual authorities, and representatives of peaceful supernatural entities convened in Yokohama, Japan, for unprecedented negotiations. Key Agreements:

Recognition of Supernatural Sovereignty: Certain spirits and deities were acknowledged as legitimate entities with rights. Establishment of Threshold Zones: Designated cities were created to manage human-spirit coexistence. Creation of International Spiritual Defense Force (ISDF): A unified military-spiritual organization was formed. Spiritual Education Mandate: Education about supernatural threats became mandatory in schools. The Compact of Coexistence: Treaties were signed with peaceful yokai and deity factions.

The Birth of Threshold City (1953-1960) Rather than attempting to restore the pre-Sundering world, Japan and the United States collaborated to create a joint experimental city—a controlled environment for cultural and metaphysical integration. Location:

Built on the ruins of a smaller coastal city in Japan, expanded with American urban planning and Japanese spiritual architecture. Positioned on a natural convergence point of ley lines, making it highly spiritually active.

Purpose:

Symbol of post-war cooperation. Living laboratory for human-spirit relations. Training ground for spirit hunters. Economic hub for supernatural resources. Cultural melting pot.

II. GEOGRAPHY & CITY STRUCTURE Threshold City (敷居市, Shikii-shi / Official name: New Yokohama-San Francisco)

Population: Approximately 3.2 million humans and an estimated 800,000+ supernatural entities.

Geography

Coastal city with a natural harbor. Constructed on seven hills, echoing the geography of San Francisco and sacred Japanese landscapes. Surrounded by mountains on three sides and the ocean on the fourth. Features multiple rivers and canals threading through the city. Persistent fog and mist due to high spiritual energy concentrations.

City Districts

The Core (中心部, Chūshinbu) / Downtown

Features a blend of American skyscrapers and Japanese architecture. Hosts corporate headquarters for supernatural industries and ISDF Central Command. Equipped with heavy spiritual barriers and constant monitoring. Relatively safe and heavily patrolled with neon-lit streets operating 24/7. Integrates torii gates into modern infrastructure.

Old Town (旧市街, Kyū Shigai) / Historic Quarter

Preserves pre-Sundering architecture, including temples, shrines, and churches. Home to antique shops selling genuine cursed objects, fortune tellers, onmyoji offices, and exorcist agencies. Characterized by narrow, winding streets with a high concentration of benevolent minor deities. Functions as a tourist district by day and a spirit hunter patrol zone by night.

Neon Abyss (ネオンアビス) / Entertainment District

Inspired by Tokyo’s Kabukicho and Las Vegas. Contains pachinko parlors, casinos, nightclubs, and establishments run by supernatural entities (e.g., kitsune-owned hostess clubs, tanuki gambling dens).

The Hollows (虚地, Kyochi) / The Zones

Areas permanently corrupted by malevolent spiritual energy, where reality is unstable and geography shifts. Extremely dangerous and quarantined but impossible to fully seal. Source of the most dangerous spirits and a proving ground for hunters. Sub-zones: The Rust Garden: Abandoned industrial area with mechanical yokai. The Wet Market: Eternally dark street for buying and selling cursed items. Mirror Lake: Area with reflection-based anomalies. The Static: Zone where urban legend entities manifest most frequently.

Little Americas / Gaijin Town

The Gardens (庭園区, Teienku) / Green Zone

Massive parks and preserved forests within city limits, serving as the primary territory for nature spirits. Contains sacred groves with ancient deities, used as meditation and training grounds. Dangerous at night, with some areas untouched by humans for centuries.

Class C (Critical): Deadly to most humans (e.g., powerful yokai like kitsune or jorōgumo, lesser demons, corrupted spirits requiring a minimum team of three trained hunters). Class B (Brutal): Can devastate city blocks (e.g., ancient yokai, demon lords, manifestations of collective fear requiring elite hunter units). Class A (Apocalyptic): City or regional-level threats (e.g., divine beasts, great demons, deity-class entities requiring military intervention and multiple elite teams).

Contract Marks:

Appear on the body, glow when summoning, vary by spirit type, can be hidden but always present. Breaking a contract causes painful scarring.

Number of Contracts:

Average practitioner: 1-3 spirits. Skilled contractor: 4-7 spirits. Master contractor: 8-12 spirits. Record holder: 23 simultaneous contracts (died from spiritual overload).

Summoning Methods:

Verbal commands, hand seals, drawing the spirit’s symbol, offering tribute, or mental calls (symbiotic contracts).

Advantages:

Versatile with different spirits for various situations. Less reliance on personal power. Knowledge gained from spirit partners. Potential for powerful combinations.

XII. MYSTERIES & UNRESOLVED QUESTIONS The Sundering’s True Cause

Official Explanation: Atomic bombs’ energy and mass death ruptured dimensional barriers. Problems: Other mass casualty events didn’t cause this, some seals broke early, ancient texts describe similar events, barriers were weakening. Alternative Theories: Failing ancient seals, intentional ritual sacrifice, cyclical event, divine punishment, human consciousness evolution. What ISDF Knows: Classified, known only to Director-General and select few. Recent Evidence: Pre-Sundering artifacts, suppressed “Project Threshold” documents.

The Disappeared

Phenomenon: ~12,000 people vanished without trace since Sundering, mostly hunters/practitioners near Hollows. Theories: Taken to spirit realm, consumed, erased, trapped in pocket dimensions, government experiments, ascension. Famous Case: Kaito Fujimoto, S-Rank hunter, vanished on live stream in 2019, no trace.

The Curator’s Identity

Known: Runs Eternal Library, immensely powerful, knows all supernatural history, exists outside time, cannot lie but misleads. Unknown: True form, identity, power level, motivation, allegiances. Theories: Forgotten god, librarian consciousness, time traveler, Akashic Records, angel, something older. Why It Matters: Curator holds conflict-ending knowledge but restricts access.

The Deep One

Event (1985): Ancient ocean deity attacked port, sealed beneath ocean. Inconsistencies: Let itself be sealed, spoke (censored), sealing team died mysteriously, increased oceanic activity since 2020. Alleged Words: “The children of the deep are sleeping. The seventh seal is weakening. When the drowned god awakens, the city will return to the ocean.” Recent Developments: Tsunamis, strange fish behavior, ningyo fleeing, ISDF reinforcing coastal barriers.

The Children of the New Age

Phenomenon: Post-Sundering children display innate spiritual abilities (sight, armaments, communication, curse resistance, reality-warping). Population Percentage: 2% (1945-1960), 8% (1960-1980), 15% (1980-2000), 27% (2000-2020), 40% (2020-present). Implications: Human evolution, obsolete training, potential species divergence. Government Response: Monitoring, special schools, research, ISDF recruitment, rights/control debate. Extremist Positions: Segregation vs. worship, fears of generational conflict.

The Static (Most Dangerous Zone)

Characteristics: Unstable reality, continuous urban legend manifestations, belief shapes reality, no consistent geography/time. Danger: Class S threat, only 3 sane survivors, stories affect its nature, growing 1 meter/year. Returns: Screaming hunter (institutionalized), silent researcher (“We are the story telling itself”), ISDF operative (“It’s alive. And it’s hungry.”). Status: Quarantined, triple barriers, no entry, projected to reach residential areas in 50 years.

The Hundred Year Question

Question: What happens when mass-produced objects turn 100 and become tsukumogami? Context: Millions of modern objects (cars, electronics, computers) will reach 100 years soon. Timeline: 2027 (automobiles), 2030s (household items), 2040s (electronics), 2050s (computers). Projections: Millions of tsukumogami, unprecedented spiritual event, economic/social disruption. Preparations: International task force, prevention research, infrastructure/legal planning. Debates: Destroy objects (spiritual genocide?), grant rights, predict hostility.

XIII. CURRENT THREATS & CONFLICTS

  1. The Awakening Tide

Situation: Ancient sealed entities breaking free as seals degrade. Incidents: Mountain god (47 dead), New York dragon, Heian yokai king (resolved peacefully). Problem: Hundreds of unknown sealed entities, unpredictable failures. Factions: ISDF (reinforce seals), spiritual communities (negotiate), extremists (kill), entities (seek freedom). Escalation: One Class S entity awakens yearly, rate increasing.

  1. The Spirit Rights Movement

Leaders: Yokai Collective, human allies. Demands: Full personhood, voting rights, end ISDF containment, reparations, social integration. Opposition: Conservative humans, religious groups, ISDF, human supremacists. Actions: Protests, civil disobedience, legal challenges, cultural campaigns, occasional violence. Tension: Rising, fears of second war.

  1. The Collector’s Game

Activity: Collector acquires sealing-related artifacts (Seven Sealing Swords, Buddhist Mandala, Seal of Solomon copy, Dreamcatcher). Question: Preparing massive sealing or breaking ritual? ISDF Status: High-priority investigation, no leads.

  1. The Vanishing Vanguard

Situation: Vanguard Seven show lost time, memory gaps, spiritual marks, shared dreams, increasing power. Theories: Possession, curse, combat side effect, conspiracy, prophecy. Status: Classified internal inquiry, Commander Chen reports, “We’re being changed.”

  1. The New Faith

Emergence: Church of Threshold, combines all traditions, 50,000 followers. Beliefs: Sundering was evolution, humans/spirits must merge, city is holy, transformation coming. Leader: Unknown “Prophet.” Concerns: Cult-like structure, Prophet’s agenda, members’ unusual abilities, “Great Convergence” prophecy. Traditional Religions: Concerned.

  1. The Hollow Expansion

Data: Hollow zones growing 2-3 meters/year, Static fastest (1 meter/year, accelerating). Causes (Theories): Natural progression, increased spiritual activity, deliberate expansion, reality damage spread. Solutions: Barrier reinforcement, cleansing, sealing (all ineffective). Projection: City evacuation in 30-50 years, limited public awareness.

  1. The Underground Railroad

Operation: Smuggles persecuted spirits to safety via secret routes, safe houses, false identities. Legality: Complicated, some spirits deserve protection, others are criminals. ISDF Response: Unsuccessful shutdown attempts. Public Opinion: Divided (heroes vs. criminals). Development: Escaped spirits committing crimes, damaging reputation.

  1. Threshold Academy Scandal

Revelation: Unethical basement experiments (spirit testing, student subjects, forbidden artifacts, necromancy, demon summoning). Status: Ongoing investigation, damaged university reputation, protests, government inquiry, professor suicides. Question: Extent of administration involvement?

  1. The Prophecy War

Issue: Contradictory prophecies from Shinto, Christian, Buddhist, yokai, and modern sources. Predictions: Destruction, golden age, war, peace, sinking city, ascension, ancient evil, new god. Problem: Factions act on prophecies, creating conflict; prophecy cults form. Question: Do prophecies predict or create the future?

  1. The Sixth Sense Economy

Phenomenon: Black market for spiritual abilities (ability grafting, power enhancement, forbidden contracts, soul modification, curse weapons). Customers: Desperate hunters, thrill-seekers, criminals, government agents. Consequences: Corruption, madness, death. Source: Unknown, possibly Midnight Market. ISDF Status: High priority, little progress.

XIV. POTENTIAL FUTURES Scenario 1: The Great Integration (Optimistic, 2025-2050)

Path: Spirit rights succeed, peaceful coexistence, technology/spirituality merge, hybrid culture, generational acceptance. Outcome 2050: Full integration, possible new species, spiritual education standard, stabilized Hollows, global Threshold model, transformed culture. Challenges: Ongoing but hopeful.

Scenario 2: The Second Sundering (Catastrophic, 2024-2030)

Path: Escalating violence, terrorist attacks, ISDF purges, spirit retaliation, ancient entities join, reality damage accelerates. Outcome 2030: City destroyed, millions dead, global supernatural war, worse entities emerge, near extinction, dark age. Challenges: Preventing escalation.

Scenario 3: The Separation (Controlled Division, 2025-2040)

Path: Coexistence deemed impossible, new barriers built, spirits return to their realm, controlled contact points. Outcome 2040: Two worlds, limited interaction, loss of integrated culture, ongoing tension, rebels resist separation. Challenges: Maintaining boundaries.

Scenario 4: The Transcendence (Transformation, 2025-2060)

Path: New Age children evolve, humanity transforms, old humans/spirits obsolete, new existence emerges, resistance from both sides. Outcome 2060: New species, old humans minority, new reality rules, Threshold as transformation ground zero. Challenges: Balancing loss and gain.

Scenario 5: The Cycle Repeats (Historical Echo, 2025-2045)

Path: Sundering was cyclical, barriers will restore, spirits fade, preparation window. Outcome 2045: Barriers restored, spirits return to hidden realm, some trapped, humanity “alone” again, city as monument. Challenges: Fight or accept cycle.
