【Anomaly Threat Agency (ATA) Classified Report】

Classification: Level 4 (Accessible to Agency Staff and above)

Anomaly Number: No. 017 Designation: 《The Woman in the Alley》

Alias:

Lost Bride

Threat Grade: A-Class Dangerous Anomaly Capable of contaminating an entire urban area alone. High encounter rate with civilians and possesses mental contamination abilities, requiring continuous monitoring.

Classification:

Ghost-type Fixed-point Manifestation Mental Interference Line-of-sight Dependent

Appearance: A woman appearing to be in her early 20s. Height approx. 165cm. Long black hair covers her face, making the eyes almost impossible to see. Wears a white dress heavily stained with mud and black spots. Upon close inspection, the stains are not dried mud but countless black handprints resembling human finger marks. The body appears slightly translucent, but footsteps are clearly audible.

First Confirmed: 20XX/MM/DD A dilapidated residential area in ██ City, ██ Prefecture. Confirmed via security footage after 5 disappearances occurred. Similar cases have since been confirmed nationwide.

Manifestation Conditions: High probability of appearance when the following conditions overlap:

Between 12:00 AM and 3:00 AM Low-traffic alleys Individuals walking alone Surroundings become unnervingly quiet Animals like dogs and cats disappear

Behavioral Patterns: Upon encounter, she stands about 20–30m ahead. Remains motionless with her head down. After approx. 10 seconds, she takes a slow step forward. Speed is approx. 2km/h. However, an abnormality occurs only when she is momentarily out of sight. Upon re-observation, the distance is reduced by more than half. This phenomenon repeats indefinitely. Eventually, she always approaches to point-blank range.

Stage 1: "Visual Recognition" The encounterer feels groundless anxiety. Increased heart rate. Chills. Ambient sounds vanish.

Stage 2: "Memory Erosion" Memories of an unknown woman flood the mind. The content is consistent: "You said you'd come for me." "Why did you leave me behind?" The victim gradually comes to believe these are their own memories.

Stage 3: "Approach" The target continues to walk. Even if one runs away, the distance closes. While surveillance cameras show no movement, she approaches to the naked eye.

Final Stage: "Accompaniment" When the distance to the target is within approx. 1m, the woman raises her head for the first time. However, to date, no survivor has been able to visually confirm her face. The victim vanishes from the spot. Only clothes and belongings are left behind.

Special Abilities: ■ Mental Erosion: The longer the encounter, the more guilt is amplified. Implants false memories of "abandoning someone" or "being the only survivor."

■ Perception Alteration: Ignores normal spatial movement once out of sight. Position does not change on GPS or laser rangefinders.

■ Electronic Interference: Within a 20m radius:

Mobile phones GPS Radio Drones fail to operate normally.

White noise appears in recorded footage.

Casualties:

Confirmed Disappearances: 87 Mentally Ill: 142 Confirmed Deaths: 0

*Disappeared persons are recorded as "Missing" rather than dead.

Response Protocol: If encountered, strictly observe the following:

Do not make eye contact. Do not respond even if your name is called. Never look back. Move from the alley to a wide road. Avoid acting alone.

Current Response: Currently, only monitoring manifestation areas and redirecting civilians away from restricted zones.

Director's Special Note:

"Anomaly No. 017 is not an anomaly that kills. It is an anomaly that 'goes somewhere with someone.' Not a single shred of evidence has been found that those who vanished are dead. That is precisely why we continue to avoid the worst conclusion."

【Anomaly Threat Agency (ATA) Classified Report】 Classification: Level 5 (Top Secret)

Anomaly Number: No. 046 Designation: 《The Moon-Devouring Door》

Alias:

Black Door Moon Gate Door of the End Entrance of No Return Yoruzakai (Night Boundary)

Threat Grade: S-Class Dangerous Anomaly A paranormal entity that rewrites space itself. To date, there are no successful cases of sealing or extermination.

Classification:

Spatial Anomaly Boundary Anomaly Perception Contamination Paranormal Domain Generator

Appearance: Upon manifestation, a single black wooden door appears unnaturally on the walls of dilapidated buildings, abandoned hospitals, schools, or apartments. The door is always ajar, and no light leaks from the gap. Beyond the door, one sees only a pitch-black space and a solitary full moon floating. The moon lacks a sense of distance; its size does not change no matter how much one approaches. A white cat is highly likely to be sitting near the entrance/exit. The cat neither meows nor moves, simply staring at the door.

First Confirmed: 20XX/MM/DD An abandoned village in the mountains of ██ Prefecture. A family of seven vanished. Furniture and daily necessities were left as they were, with only the single open door leading to the anomalous space. One of the earliest anomalies that led to the founding of the Agency.

Manifestation Conditions: Probability increases under the following conditions:

Nights of the new or full moon 12:00 AM – 4:00 AM Buildings where human traffic has ceased Structures left neglected for long periods Locations where numerous fatal incidents occurred Even if it vanishes, it reappears in a different region months or years later.

Behavioral Patterns: Stage 1: "Induction" Anyone who discovers the door is overcome by an urge to "look inside." Occurs regardless of mental resistance strength.

Stage 2: "Gaze" Continuing to look into the darkness brings a sensation of being watched by someone else. Biological responses indicate extreme terror.

Stage 3: "Observation" Multiple eyes appear in the darkness. Numbers range from dozens to thousands. Placement and count vary by observer. They do not appear on cameras or drones.

Stage 4: "Invitation" From the depths of the darkness, the voices of the "person one wants to see most"—family, lovers, friends, the deceased—begin to be heard. The content is consistent:

"Over here." "Come get me." "Don't leave me alone."

Final Stage: "Crossing" If the target takes even one step beyond the door, the boundary closes. To date, no return cases exist.

Special Abilities: ■ Spatial Isolation: Beyond the door does not correspond to any coordinates on Earth. Laser measurements calculate the distance as infinite.

■ Perception Manipulation: The scenery seen varies by observer. Examples:

Night forest Abandoned station School Sea Hallway of one's home

However, external observation shows only darkness.

■ Mental Induction: Reads the target's

Regret Lingering attachment Sense of loss

and utilizes them to lure the target inside.

■ Electronic Disablement: Within a 50m radius of the door:

GPS Radio Mobile phones Infrared cameras Thermography

accuracy drops significantly.

Regarding the White Cat: The Agency classifies it as Sub-Entity No. 046-A. Danger Level: C. The cat never enters the door. It does not harm humans. However, if the cat leaves the spot, the door vanishes within 30 seconds. This relationship remains unexplained.

Casualties:

Confirmed Disappearances: 312 Investigators: 58 Missing Unmanned Probes: 147 Lost Returnees: 0

Recovered Audio Logs:

"...Eyes." "So many are watching." "The moon is getting closer..." "The cat... told me not to look this way..." (Silence follows)

Response Protocol: If encountered, strictly observe the following:

Do not look inside the door for more than 5 seconds. Do not respond even if you hear voices. Do not approach the door; evacuate immediately. Do not touch or chase away the white cat. Seal the site until the door vanishes.

Current Status: Indestructible. All means, including explosive demolition, incineration, and high-power laser irradiation, are ineffective. Currently, monitoring manifestation points and prioritizing civilian evacuation and information suppression.

Director's Special Note:

"It is thought that the Moon-Devouring Door is not an anomaly, but the 'boundary' itself. No one knows where the door leads. But one thing is certain. The door is not choosing people. The other side is peering into this one."

【Anomaly Threat Agency (ATA) Classified Report】 Classification: Level Ω (Accessible only to Director, Deputy Director, and Division Zero) Warning:

This document carries a risk of cognitive hazard due to No. 001. Perform a mental resistance check before viewing. Direct observation via portraits, video, or the naked eye within this text is prohibited.

Anomaly Number: No. 001 Designation: 《The Pallid Idol》 Official Codename: 《SERAPHIM》

Alias:

The Blue God Porcelain Goddess Observer of the End The First Anomaly The Idol Silent Saint

Threat Grade: EX-Class (Terminal Disaster Designation) No. 001 possesses the potential to lead civilization to its end single-handedly. Highest danger level among all currently confirmed anomalies.

Classification:

Divine Entity Cognitive Hazard Reality Warper Mental Erosion Causality Manipulation Transcendent Entity

Appearance: An entity in the form of a woman. Estimated height approx. 170cm. The entire body has a white texture reminiscent of porcelain or marble, with multiple black cracks running across the skin. A third eye that glows pale blue exists on the forehead, and the normal eyes glow with the same color. Pure white hair continues to sway as if drifting in the air, unaffected by gravity. The attire cannot be distinguished as either priestly robes or armor, and unknown characters are engraved in the decorations. Some perceive the form as "beautiful," while others testify it is the "most terrifying existence in the world." Testimonies vary by observer.

First Confirmed: 19XX/MM/DD First observed in a massive underground temple discovered beneath the ██ Mountain Range. All 34 members of the first investigation team knelt in silence; while biological functions were maintained, their personalities were completely lost. Subsequently, the underground temple vanished suddenly during the investigation. No manifestation points have been confirmed since.

Behavior: No. 001 basically does not move. However, it interferes with the observer's perception itself. From the moment of observation, the target is "recognized" by No. 001. Thereafter, they continue to be affected regardless of distance or time.

Stage 1: "Recognition" Headaches. Tinnitus. Loss of sense of time. Hallucinations of seeing blue light.

Stage 2: "Revelation" Encountering No. 001 in a dream. Conversation is impossible. However, awakened subjects testify: "I have learned the truth of the world." The content is inconsistent among all subjects.

Stage 3: "Collapse" Porcelain-like cracks appear on the skin. No medical abnormalities are confirmed. No pain. However, the mind rapidly deviates from reality.

Final Stage: "Idolization" The target kneels of their own accord and stops moving. Respiration and heart rate are maintained. The body gradually whitens and hardens, turning into a "living statue" that leaves only traces of having been human. To date, no recovery cases exist.

Special Abilities: ■ Cognitive Hazard: The influence begins just by knowing about No. 001. Infection is possible through any medium, including photos, video, audio, and text.

■ Reality Warping: Disturbances in physical laws are confirmed within a radius of several hundred meters.

Time stoppage Spatial distortion Gravitational anomalies Loss of light occur intermittently.

■ Causality Manipulation: In all records of attempts to attack No. 001, no result of "the attack succeeded" exists. Causes vary—weapon failure, the shooter tripping, cancellation of orders—but the result is always a failed attack.

■ Anomaly Dominance: Class A and lower anomalies do not approach the vicinity of No. 001. Some individuals kneel and cease activity. Even S-Class anomalies have been observed avoiding contact.

Casualties:

Confirmed Idolizations: 189 Mental Collapses: 1,432 Deaths: 0 Successful Exterminations: 0 Successful Sealings: 0

Special Notes: No aggressive behavior has ever been confirmed from No. 001 to date. Despite this, the Agency designates it as the highest alert target. The reason is simple: "It rewrites the world simply by existing."

Response Protocol: If No. 001 is confirmed, strictly observe the following:

Do not look directly at it. Do not attempt conversation. Do not approach within a 1km radius. Recording of photos, video, or audio is prohibited. Contact by anyone other than Division Zero is strictly prohibited.

Division Zero Top Secret Record:

"Investigation results show no hostility or malice toward humanity from No. 001. Rather, it shows behavior as if observing humanity. However, the same sentence is always left at the end of observation records: 'That is not a god. It is something that, after staring at a god for too long, discarded the vessel called human.' Furthermore, the sealed document left by the Agency's founder contains only one sentence: 'If the day ever comes when No. 001 stands up on its own—the Anomaly Threat Agency will have fulfilled its purpose.'"
