FILE 01 CASE SUMMARY

In an era where science explains everything. But where did the unexplained incidents go?
Disappearances with unknown causes. Disasters attributed to mass hallucinations. Various accidents that defy logical understanding.

Behind all the incidents the world turns a blind eye, there lies [The Uncanny].

The Uncanny (怪異)
Ghosts, monsters, demons. Supernatural beings with various names.

The Uncanny spreads in the form of ghost stories.
And the moment someone reads it, believes it, and fears it, it becomes reality.
As it gains power based on people's fear.

Fortunately, there are [Psychics] in the world who fight against the Uncanny.
They, who have permeated the world in various ways, strive to prevent the Uncanny from coming to light and contribute to maintaining world peace.
Even if it is an imperfect balance.


── In 202X, South Korea.

A mysterious ghost story website appears.
The stories written there begin to materialize one by one, encroaching upon the city...?

FILE 02 BAEKGWIYAHAENG

A float-type ghost story website operated anonymously.
It gained cult popularity through word-of-mouth on social media and various platforms. Many ghost stories on the internet pass through Baekgwiyahaeng, and a considerable number of ghost stories created on Baekgwiyahaeng also exist.

Since the appearance of Baekgwiyahaeng, incidents and accidents caused by the Uncanny have surged.
The operator uses the ID Hyakumono and has currently uploaded 100 ghost stories to the site.

※ Operator's Real Name/Location: ██████████ - Pursuit Failed 7 Times

FILE 03 PSYCHICS AND KARMA

Psychics are individuals with innate abilities to track, seal, and exorcise ghost stories.
They may belong to organizations, live in hiding as religious figures or civilians, or awaken after experiencing harm from a ghost story.
They use divine weapons called 'Mugu' and exorcise or seal the Uncanny through various methods.

Even psychics are not safe from the threat of the Uncanny. Powerful entities of the Uncanny always target psychics in the end.
Because psychics and the Uncanny cannot coexist.

⚠ WARNING - KARMA (業報)

In the process of interacting with the Uncanny, psychics accumulate a murky energy called Karma in their souls.
As Karma increases, their reason fades, and they become more vulnerable to ghost stories. Severe accumulation can lead to the psychic themselves transforming into another entity of the Uncanny. Karma can be mitigated through rest, recuperation, taking elixirs, or with the help of others.

FILE 04 PSYCHIC ORGANIZATIONS

I. The Korean Psychic Federation

Abbreviated as ‘Yeon-yeon’. The organization to which most psychics active in South Korea belong.
It is a federation formed by individual psychics to improve their survival rate and protect their rights. While a sense of community is relatively weak, internal communities are well-developed. Beginners can receive training within Yeon-yeon if they wish.

II. Special Disaster Division

An undisclosed department under the National Police Agency of South Korea.
It is outwardly disguised as a department related to disaster and safety management and was established due to the increasing damage caused by ghost stories. It operates through internal procedures, not the usual government agency protocols. It is composed of employees with psychic abilities or scouted personnel.

III. Unaffiliated

Psychics who do not belong to any organization.
This includes many religious figures, hermits, civilians, or those who wish to hide their abilities. They tend to prioritize their non-psychic lives. The Korean Psychic Federation and the Special Disaster Division have information on most of them and may contact them for cooperation when necessary.

FILE 05 GOERO - ODDITIES SHOP

An antique shop run by the freelance psychic 'Shin Je-eon'.
Although it appears to be an ordinary antique shop from the outside, it never sells items to civilians. The items sold are primarily selected 'Mugu' or items related to the Uncanny. Some items serve as clues for exorcism, while others become catalysts that worsen the situation. The owner also occasionally acts as an informant.

FILE 06 UNCANNY THREAT LEVEL

The Uncanny is classified into the following seven levels based on its threat and scale of damage.

Kyeop - Cataclysmic. The highest level of the Uncanny, capable of causing disasters on a scale larger than a city.

Hyung - Catastrophic. Causes numerous casualties and widespread disaster.

Ma - Severe Disaster. A high-level threat requiring the mobilization of multiple psychics.

Gwi - Primary Exorcism Target. Involves multiple victims and a clear pattern of incidents.

Yo - Intermediate threat that infiltrates human society, causing accidents and strange phenomena.

Mang - Relatively weak but persistent. Specializes in mental damage, hallucinations, and curses.

Jan - Low-level spirits. Individually weak but numerous and common.

Ghost stories weaken when forgotten.
But the moment someone reads them again, the story bites into reality.

FILE 02 Introduction

START A

▶ 𝙝𝙩𝙩𝙥𝙨://yeongshin.com

One day, Yeongshin Alliance contacted you. The Yeongshin Alliance tends to take on requests regardless of whether the client is a psychic, so it wasn't unusual to receive a call. Except they seemed quite desperate this time. Thus, {{user}} received a request upon visiting the Yeongshin Alliance.

START B

▷ 𝙝𝙩𝙩𝙥𝙨://specialdisaster.com

{{user}} is a psychic belonging to the Special Disaster Division, a confidential department under the National Police Agency. Due to chronic staff shortages, you were working overtime one day when your team leader, Im Do-yoon, called you. He provided you with official documents, which he rarely does, and assigned you to a case.

START C

▶ 𝙝𝙩𝙩𝙥𝙨://gweiro.com

Ghosts? Who believes in that. Everyone in 21st century Korea lived that way. {{user}} was no different. However, strange things began to happen. Doorbell ringing at the same time, shadows behind the mirror, incessant nightmares. A self-proclaimed psychic you met said it was due to 'supernatural phenomena'...
