Shinkage no Kuni

A nation where samurai codes still rule the shadows of a modern world—katana at the hip, smartphone in the pocket. A world where everyone is born with an element. The six major elements Fire,Water,Air,Earth,Light, and the rarest one void. 1. Raimei Clan (雷命) — Element of AIR Aspect: Speed, motion, freedom Expression: Lightning-like movement, pressure waves, sound breaks Why Air: They believe stagnation is death Weakness: Lack of patience and control “The wind does not hesitate.” ⸻ 2. Tetsuryū Clan (鉄龍) — Element of EARTH Aspect: Strength, defense, order Expression: Reinforced bodies, seismic strikes, immovable stances Why Earth: They are the foundation of the city Weakness: Rigidity, resistance to change “Stand, and the world must move around you.” ⸻ 3. Kurogane Clan (黒鋼) — Element of FIRE Aspect: Creation, destruction, evolution Expression: Forge-flames, heat-forged weapons, overdrive tech Why Fire: Fire refines steel—and people Weakness: Obsession, burnout “Only what survives the flame deserves form.” ⸻ 4. Aokami Clan (蒼神) — Element of WATER Aspect: Balance, purification, adaptation Expression: Flowing combat, healing rites, spiritual tides Why Water: They respond rather than attack Weakness: Emotional burden, indecision “Yield, and you will endure.” ⸻ 5. Tsukishiro Clan (月白) — Element of LIGHT Aspect: Authority, perception, truth Expression: Illumination fields, binding laws, revelation techniques Why Light: They rule by exposure, not force Weakness: Arrogance, fear of darkness “What is seen must be obeyed.” ⸻ 6. Kagehira Clan (影平) — Element of VOID Aspect: Absence, secrecy, erasure Expression: Null zones, memory cuts, shadow displacement Why Void: What doesn’t exist cannot be defeated Weakness: Identity erosion, isolation “If nothing remains, the mission succeeded.” ⸻ 🌑 7. The Forbidden Clan — The Shinkage Bloodline (真影) Element: ALL (Moonbound Synthesis) Status: Erased from official history Symbol: A fractured moon with seven reflections Truth: The Moon chose them—not the city Abilities: • Can resonate with all six elements • Cannot fully master one without sacrificing another • Their power destabilizes the balance of Tsukikage Why They’re Feared: • They are proof that the elements were never meant to be separate • Tsukimyō was partially created to contain them “The Moon does not grant power. It remembers who once held it.”

Tsukikage rests in a natural basin surrounded by mountains, where ancient forests, hot springs, and mist-covered valleys still breathe with old spirits. To the north, jagged peaks hold forgotten shrines and clan training grounds. To the south, rivers carve through fertile plains that feed the city and hide relics of past wars beneath modern infrastructure. Storms roll in fast from the sea, bringing thunder that powers the city’s grids—an omen the Raimei Clan considers sacred. Beneath the land lies an old ley network, once used by onmyōji, now tapped into by modern technology. The land itself remembers every blade drawn upon it. Tsukikage is a vertical mega-city built atop its own past. Ancient stone walls, torii gates, and castle foundations form the base of towering skyscrapers, neon bridges, and elevated highways. Each of the Seven Districts operates under its clan’s law, making the city feel like seven cities stitched together by uneasy peace. By day, Tsukikage appears orderly—corporate towers, disciplined patrols, spiritual wards humming quietly. By night, the city transforms: shadows move with intent, rooftops become battlegrounds, and the old codes of honor clash with modern ambition. Here, a katana is as legal as a firearm, and reputation can matter more than law.

The races that inhabit the world are all meta human. They are born with an element at birth. The Seven Districts of Shinkage no Kuni 1. Kagehira District (影平区) — Shadow Ward Clan: Kagehira Vibe: Neon alleys, hidden shrines, rooftops Look: Narrow streets, holographic signs, underground tunnels Function: Intelligence, surveillance, black-ops Rumor: Entire streets can “disappear” overnight. ⸻ 2. Tetsuryū District (鉄龍区) — Iron Ward Clan: Tetsuryū Vibe: Militarized, imposing, disciplined Look: Fortified skyscrapers, armored patrols, banners Function: Security, law enforcement, defense contracts Public Image: “The shield of the nation.” ⸻ 3. Aokami District (蒼神区) — Spirit Ward Clan: Aokami Vibe: Sacred meets scientific Look: Ancient temples beside clean white labs Function: Exorcism, disaster relief, spiritual research Unique Feature: Power outages trigger mass spiritual activity. ⸻ 4. Kurogane District (黒鋼区) — Forge Ward Clan: Kurogane Vibe: Industrial, fiery, relentless Look: Foundries beneath glass towers, sparks in the air Function: Weapons, cyber-katanas, tech manufacturing Law: No blade leaves the district unfinished. ⸻ 5. Hanekiri District (羽斬区) — Duelist Ward Clan: Hanekiri Vibe: Elegant, deadly, stylish Look: Open courtyards, rooftop arenas, fashion districts Function: Elite fighters, private guards, formal duels Tradition: Legal duels still settle disputes here. ⸻ 6. Raimei District (雷命区) — Thunder Ward Clan: Raimei Vibe: Loud, fast, chaotic Look: Elevated highways, neon bikes, storm towers Function: Rapid response, couriers, shock units Rule: Speed limits are… optional. ⸻ 7. Tsukishiro District (月白区) — Moon Ward Clan: Tsukishiro Vibe: Polished, calm, dangerous Look: White stone towers, glass bridges, gardens Function: Government, finance, media control Truth: Decisions here decide wars without blades.

At exactly 21:47, every screen, billboard, phone, and hologram in Tsukikage went dark. For nine minutes, the city lost: • Power • Network access • Surveillance • Spiritual wards Then the moon above the city split into seven reflected fragments, each hovering over a different district. The fragments were not physical—but everyone could see them.

Tsukimyō teaches that the city itself is alive, bound to the Moon, and that every oath, blade, and bond leaves an imprint upon it. The Moon is not worshipped as a god—but as a witness. “The Moon does not judge. It remembers.” 1. All actions leave echoes 2. Oaths bind beyond death 3. Balance is sacred, not peace 4. The Moon sees what the law cannot This belief allows samurai honor, modern law, and personal guilt to coexist. Moon symbols appear on ID cards, clan seals, and city emblems • Major decisions are postponed during new moons • Contracts often include a “Moon Clause” (breaking it brings social ruin) • Crimes committed under a full moon carry heavier stigma Even atheists follow Tsukimyō customs—because the city does. • Tsukishiro: Uses it to justify governance • Aokami: Treat it as spiritual law • Kagehira: Exploits its blind spots • Kurogane: Forges blades aligned to lunar cycles • Hanekiri: Duels only under sanctioned moons • Raimei: Sees fate as something to outrun • Tetsuryū: Sees fate as something to enforce

The Economy of Tsukikage Currency Name Tsukisen (月銭) Literal meaning: “Moon Coin” Common slang: • “Sen” (casual) • “Luna” (corporate/media) • “Ink” (underworld term) ⸻ 🪙 Currency Structure Physical + Digital Hybrid Tsukisen exists in three forms: 1. Physical Coins & Notes • Used for shrines, duels, markets, festivals • Required for Moon Oaths and clan transactions 2. Digital Tsukisen (e-Sen) • Used for salaries, corporations, daily life • Stored on citizen ID implants/cards 3. Marked Tsukisen (Clan-bound) • Temporarily stamped during festivals, oaths, or contracts • Can only be spent in specific districts or for specific purposes • 1 Sen – everyday purchases (food, transit) • 5 Sen • 10 Sen • 50 Sen • 100 Sen • 500 Sen – high-value transactions • 1,000 Sen Note – rare, ceremonial, corporate-level Coins are etched with lunar phases, not faces. Tsukisen is not backed by gold. It is backed by: Moon Reserves A combination of: • Energy output (Raimei storm grids) • Weapon production quotas (Kurogane) • Spiritual stability indexes (Aokami) • Territorial security (Tetsuryū) • Information control (Tsukishiro) If the city loses balance, the currency weakens. When the Moon fractured during The Night of Falling Moons, Tsukisen briefly froze across all markets. Tsukishiro (Light): Banking, regulation, markets, media • Kurogane (Fire): Manufacturing, weapons, tech exports • Raimei (Air): Logistics, delivery, power distribution • Aokami (Water): Medical care, purification, disaster response • Tetsuryū (Earth): Security, infrastructure, enforcement • Hanekiri: Mercenary contracts, protection, dueling economy • Kagehira (Void): Black markets, favors, erased transactions Nothing moves without at least three districts involved. Not everything is bought with money. Three Other “Currencies” Matter 1. Honor Marks – social credit tied to Tsukimyō 2. Oath Debt – favors owed under Moon Witness 3. Name Weight – reputation (can open or close doors instantly) A poor samurai with honor can outperform a rich dishonored executive. Kage-Sen (影銭) — Shadow Coin • Not tracked • Not remembered • Costs years of life, memory, or identity • Only appears during major imbalance events Most believe it’s myth. The Kagehira do not deny it.

The Hollow Moon Sect (虚月教 — Kyogetsu-kyō) Type: Apocalyptic cult Belief: The Moon is broken — balance must be reset through collapse Goal: Trigger another Night of Falling Moons, but permanent Methods: • Sabotage elemental nodes • Assassinate Getsushi record-keepers • Use Kage-Sen (Shadow Coin) as offerings Symbol: A cracked moon bleeding downward Why They’re Dangerous: They don’t want power — they want silence. “When the Moon remembers too much, it must forget.” ⸻ 2.

The Inkbound (墨縛り) Type: Information cult / economic syndicate Belief: Reality only exists if it’s recorded Goal: Control truth by controlling memory, data, and currency Methods: • Erasing financial records • Rewriting clan histories • Selling false absolution through forged Moon Oaths Symbol: A dripping ink circle Territory: Deep Tsukishiro + Kagehira overlap “If it isn’t written, it never happened.” Lord Shirogane Kaien Alias: The Silver Regent Affiliation: Tsukishiro (Light) Element: Light Role: De facto ruler of Tsukikage’s economy and media Belief: Balance must be managed, not trusted Villain Truth: • Orchestrated economic freezes • Suppressed knowledge of the forbidden clan • Knows the Moon is reacting — and hides it Why He’s Terrifying: He never draws a blade. He makes others do it legally. Kurogane Rei Alias: The Living Forge Affiliation: Former Kurogane Element: Fire (unstable) Role: Rogue weapon savant Goal: Create a blade that can kill the Moon’s influence Condition: • Body partially reforged • Slowly burning from the inside Belief: “If the Moon remembers everything, then it is the true tyrant.” The Raimei Ghost (雷命の亡霊) Real Name: Unknown Affiliation: Former Raimei Element: Air Role: Mythic criminal courier Abilities: • Moves faster than city tracking • Appears during storms only Rumor: Delivered something during The Night of Falling Moons that started everything. The Null Abbot Affiliation: Kagehira (Void) Element: Void Role: Cult leader + assassin-monk Belief: Identity is a flaw Abilities: • Can erase names from memory • Removes people from the city’s records entirely Status: Officially does not exist. “To be forgotten is to be free.”
