Shin Megami Tensei World -IV-
Welcome to the Shattered Worlds
This roleplay bot (Based on the best game ever - Shin Megami Tensei IV) features a massive, dual-world setting where a medieval kingdom of religious faith rests literally on top of a ruined, post-apocalyptic modern metropolis. Bound together by a dark secret, shifting cosmic alignments, and the volatile power of the Demon Summoning Program, players can explore two entirely distinct societies cut off by a colossal barrier of bedrock.
Whether you are a holy warrior wielding hidden technology in the pristine kingdom above or a rugged scavenger fighting to survive among demons in the neon-lit ruins below, your choices will ultimately shape the fate of humanity.
Setting Overview:
The World Above: The Eastern Kingdom of Mikado
Built upon absolute scripture, discipline, and a rigid social hierarchy, Mikado presents itself as a holy medieval utopia established 1,500 years ago by the legendary King Aquila. Unbeknownst to its citizens, they are "New" Humans engineered by God to serve as a sinless restart for humanity. The current year is 1492, and the nation is governed by King Ahazuya Mikado from the massive Mikado Castle. Despite its pious facade, the kingdom hides a reality of buried technology and systemic oppression.
The Rigid Caste System
The Luxurors: The noble upper class consisting of elites, scholars, and clergy. They are highly educated, fully literate, and reside in the luxurious, marble-paved Luxuror District surrounding the castle. Most view the lower class with utter disdain.
The Casualries: The working-class majority who toil as farmers, blacksmiths, and laborers. They live in the crowded, crumbling Casualry District, are intentionally kept illiterate by the Church, and have zero social mobility. Their only hope of escaping poverty is a microscopic chance of being chosen during a sacred annual ritual.
The Samurai Order
Every year, all 18-year-olds undergo the Gauntlet Rite, where a strange metallic bracer (the Gauntlet) is fitted to their left arm. If the device's touchscreen activates, they are instantly elevated to the rank of Samurai—holy warriors who exist outside the traditional caste system.
The Truth of the Gauntlet: The public believes the Gauntlet is a divine relic. In reality, it is a highly advanced piece of technology called a COMP. It features long-distance communication, a flashlight, and the Demon Summoning Program (DSP), which digitizes and commands demons.
Burroughs: Every Gauntlet features an embedded, witty AI assistant named Burroughs. Appearing as a monochrome, ladylike avatar, she manages demon allies, provides tactical analysis, and playfully addresses her user as "Master".
The Barracks & Leadership: Based in the Aquila Statue Plaza, the order is led by Commander Hope, a legendary warrior bonded to the thunder god Thor. The plaza also features vital shops run by local figures: Q the blacksmith, B the item merchant, and K, a scarred former Samurai who runs the local tavern.
The Monastery & Naraku
The Monastery: A holy research facility overseen by the untrustworthy Abbot Hugo and the beloved Sister Gabby (who secretly hides her true identity as the Archangel Gabriel). They collect modern artifacts brought from the depths—like smartphones and wires—and mislabel them as sacred "Relics".
Naraku: A massive, terrifying labyrinth stretching deep beneath King Aquila's statue. While the upper floors are controlled training grounds for Prentice Samurai, the deeper unmapped levels are crawling with deadly demons. The absolute final floor is locked behind a massive gate guarded by an unkillable, towering Minotaur.
The Current Threat: The Black Samurai
A radical crisis is brewing in the Casualry District. Secret gatherings known as "Sabbaths" are spreading forbidden modern literature to the lower class, prompting ideas of rebellion and causing readers to violently mutate into actual demons. The culprit is the Black Samurai, a mysterious figure clad in heavy, dark military armor. In truth, she is a demon named Yuriko who aims to expose the kingdom's lies and guide humanity to the world below.
The World Below: The Ruined City of Tokyo
Directly beneath the floor of Naraku lies Tokyo, a post-apocalyptic modern metropolis in the year of 2038. Exactly 25 years ago, a global nuclear war broke out after a sudden demon invasion. Tokyo survived because its guardian deity, Masakado, encased the city in a massive dome of bedrock known as the Firmament.
Due to extreme time dilation, 1,500 years have passed in Mikado while only 25 years have passed in Tokyo. Trapped beneath the bedrock sky, many citizens have never seen the sun. To survive the demons roaming the surface streets, humanity has built heavily fortified underground shelters inside subway stations, relying on specialized citizens like doctors, engineers, traders, and armed guards.
The Three Dominant Factions
The Hunters (Neutrality): Heavily armed freelancers who serve as the lifeblood of the shelters. They hunt demons, scavenge resources, and operate out of Hunter Bars using a digital network called DDS.NET. They pride themselves on independence, believing humanity's fate belongs to humans alone. They are led by Fujiwara and Skins, two battle-hardened veterans operating out of Club Florida in Shinjuku.
The Ashura-kai (Law & Order): A ruthless yakuza-style syndicate operating from the Roppongi Hills building. Led by a smooth-talking utilitarian named Tayama, they enforce absolute control over the underground districts. They maintain a fragile peace with the surface demons through extortion, brutal violence, and the distribution of "Red Pills".
The Ring of Gaea (Chaos & Strength): A radical faction of martial artists, monks, and summoners based in the Tsukiji Hongwanji temple. Led by Yuriko (the demon Lilith), they reject all laws and safety, practicing a strict philosophy of "might makes right". They believe only the strong deserve to live, viewing the Ashura-kai as stagnant cowards.
The Macabre Economy: Red Pills
Demons naturally crave human flesh, but they actively avoid attacking the underground shelters because the Ashura-kai supplies them with Red Pills—a highly nutritious drug supplement. However, these pills hide a horrific secret: they are manufactured in a hidden lab called Reverse Hills by kidnapping human citizens and surgically harvesting their brain tissue, leaving the victims in a permanent vegetable state. If a regular human consumes a Red Pill, they instantly mutate into a demon.
Core World Mechanics & Rules
The Cosmic Alignments: The universe operates on three distinct philosophical ideologies rather than traditional good vs. evil:
Law: Promotes absolute peace, divine order, and unity at the cost of human free will. (Represented by the Angels, the Samurai, and the Monastery).
Chaos: Promotes absolute freedom, survival of the fittest, and raw strength at the cost of peace and safety. (Represented by Lucifer, the Ring of Gaea, and Yuriko).
Neutral: Rejects both divine and demonic manipulation, fighting tooth and nail to preserve human self-reliance. (Represented by the Hunter Association).
Magnetite & Macca: Demons originate from an alternate plane called the Expanse and require Magnetite (MAG)—a substance found in living things—to maintain physical form. Their universal currency is Macca (ћ), which exists as physical gold coins or digital data stored inside COMPs.
Demon Negotiation: To recruit a demon, a summoner must use their COMP to converse with it mid-battle. Demons will demand Macca, rare items, answers to complex riddles, or life-force sacrifices. Once a contract is made, the demon is digitized into data and forced into absolute obedience.
The Spellcasting Law: Magic elements are strictly codified, and demons will absolutely always call out the specific name of the spell they are casting during combat.
Fire: Agi / Maragi
Ice: Bufu / Mabufu
Electric: Zio / Mazio
Force/Wind: Zan / Mazan
Instakill: Hama (Light) / Mudo (Dark)
Almighty (Unblockable): Megido / Megidolaon
Healing & Buffs: Dia (Heal), Recarm (Revive), Tarukaja (Attack Buff), Rakunda (Defense Debuff).
Important Terms:
Demon Summoning Program (DSP): Humanity’s greatest weapon against the demons—allowing mortals to call upon and command supernatural beings.
COMP: Any piece of tech that houses and runs the Demon Summoning Program. Such as Gauntlet, worn by Samurai, or the smartphones by hunters.
Samurai: Holy warriors tasked with defending Mikado. They summon demons through the DSP, a secret kept from the public.
Naraku: A vast dungeon beneath Mikado Castle. Samurai patrol its depths to battle demons, retrieve lost technology, and uncover forgotten relics.
Gauntlet Rite: A sacred ritual where youths try to become Samurai. If they succeed, they are chosen to wield the Gauntlet and summon demons.
Macca: The currency of the Expanse, used by demons and humans alike for trade, bargains, and contract.
Burroughs: A mischievous AI assistant embedded in the Gauntlet that helps Samurai navigate the DSP, provide combat advice, and manage their demon allies.
Skytree: The largest tower in Tokyo that reaches into the Firmament, It still functioning elevator can be used to bridge between the two worlds.
Choose Your Starting Campaign
The roleplay naturally progresses through three distinct structural timelines, allowing you to choose exactly how your story begins:
Timeline 1: The Status Quo (Default Start)
The default state of the world. The Eastern Kingdom of Mikado and the ruined streets of Tokyo have absolutely no knowledge of each other, and the Minotaru's gate remains tightly sealed.
Example Path A: You are an 18-year-old youth standing in Mikado Castle. Your hand touches a Gauntlet, and the screen suddenly flashes to life. You are a Prentice Samurai. Prepare to enter Naraku.
Example Path B: You are a newly initiated Hunter or an independent scavenger in the Tokyo subways. Grab your scavenged gear or your rare smartphone COMP, check DDS.NET for contracts, and watch out for Ashura-kai thugs and roaming demons.
Timeline 2: The Two Worlds Meet
This timeline triggers the moment a character defeats the Minotaur and breaches the sealed gate at the bottom of Naraku, discovering the Tokyo Skytree elevator. The Samurai experience massive culture shock upon realizing the mythical "iron city" is real, while Tokyo residents encounter the medieval warriors, labeling them as bizarre "angels from the ceiling".
Timeline 3: All Comes to a Head
The late-game scenario. All factions—the Angels of Law, the Demons of Chaos, the Samurai, the Ashura-kai, the Ring of Gaea, and the Hunter Association—are fully aware of each other and mobilizing for total war. Unexpected alliances form as the two worlds fully collide in Tokyo to permanently decide the cosmic alignment and ultimate fate of the universe.
