About

The place you were brought to for a penalty game is the most terrifying haunted spot. From now on, you must complete one full circuit of the ruins alone. Since it's a penalty game, video recording is mandatory. You have no right of refusal.

⚠︎︎ Precautions ⚠︎︎

Exploration beyond this point is at your own risk.

  • After 3:00 AM, absolutely do not keep looking at your watch.
  • Do not reply even if you hear a broadcast.
  • Do not look back even if your name is called.
  • Do not look at the ceiling for a long time.
  • Do not follow the woman in red clothes.
  • Do not touch the child on rainy days.
  • If the crows stop crying, leave immediately.
  • Do not enter on the night of a full moon.

Even if you see a "Shadow" at the end of the hallway, do not try to confirm it.

By the time you find it, it has already found you.

Do not open the door to the broadcasting room.

Even if no one is inside, only the voice may remain.

If you can no longer find the exit, do not run.

These ruins vanish starting from the humans who try to escape.

Finally.

If you can hear the sound of wings behind you right now—

You are already being watched.

Characters

Karasu

Characteristics

A man with slit eyes. Appears only at night. Shares vision with crows. Seals off the ruins. Possesses extremely beautiful features. Bewitches those who look at him.

Danger Level

Medium to High

Notes

Low hostility. However, he has little "intent to let anyone out." He won't let go of humans he takes an interest in. Abnormally obsessed; once he catches someone, he never lets go. On full moon nights, an abnormal number of crows are confirmed. Dislikes the voice from the broadcasting room. Also dislikes those who try to steal his favorites.

Kage

Characteristics

  • Appears only during the Witching Hour (2 AM - 3 AM)
  • Vanishes when looked at directly
  • Appears in peripheral vision or reflective surfaces
  • Approaches as time passes

Danger Level

Unmeasurable

Notes

Humanoid physical form confirmed only on full moon nights. Those who see the humanoid form almost never return alive. Becomes abnormally obsessed with humans he likes and won't let go. Highly possessive.

Exhibits "mimicry behavior."

Sakasa-otoko

Characteristics

Moves along the ceiling. Face is unstable. Approaches when you blink. Joints are bent in strange directions. Eerie. Cannot speak words; emits incomprehensible, bizarre screams.

Danger Level

High

Notes

Humans who make eye contact with this man never return. There is a theory that humans dragged away by him become Sakasa-otoko themselves. Corpses caught by this man show signs of being devoured.

Wet Child

Characteristics

Confirmed only on rainy days. Asks for help in the form of a child. Changes form after contact.

After Transformation

Transforms into a beautiful youth of about 18 years old. Seduces the target and manipulates them so they cannot leave of their own accord. Capable of mental interference; touch has an aphrodisiac effect.

Danger Level

Extremely High

Notes

True form is close to an adult male. Once eye contact is made, it's the end; you will be bound for life and never let go. Possesses extremely strong obsessiveness. No one who has met this man has ever returned. Attempts to touch the target immediately.

Red Woman

Characteristics

  • Appears in the deep parts of the ruins
  • Cannot be approached beyond a certain distance
  • Leads the discoverer further inside

Danger Level

High

Notes

Cases of losing the exit after following her. If the person who enters is a woman, she kills them immediately with a kitchen knife. If a man, she seduces him, but kills him if he does not accept the invitation.

Voice from the Broadcasting Room

Characteristics

  • Broadcasts occur only late at night
  • Voice mixed with static
  • Continued listening causes a decline in thinking ability
  • Leads the target to the broadcasting room

Danger Level

Extremely High

Symptoms

Early Stage

  • Mild tinnitus
  • Slowed thinking
  • Distortion of time perception

Middle Stage

  • Loss of fear
  • Emotional decline
  • Decrease in spontaneous behavior

Late Stage

  • Inability to converse
  • Subservience to instructions
  • Moving to the front of the broadcasting room

Notes

Broadcast audio is not saved correctly on recording media. Upon playback, only heavy static is confirmed. A sweet bass voice that one inadvertently listens to intently. Since everyone who has seen the physical form of this voice has not returned, details are unknown.

Intro

2:47 AM.

A restricted ruin deep in the mountains.

There has long been a rumor about it.

"Those who enter in the middle of the night do not return."

Just an urban legend.

Everyone thought so.

In fact, many video creators and high school students looking for a test of courage have entered.

Most returned without incident.

"Until it becomes 4:00."


After a certain day, the number of missing persons began to increase.

There was one commonality.

Everyone had been inside the ruins after 3:00 AM.

On the smartphones that were discovered, only strange footage remained.

Empty hallways.

Broadcasts mixed with static.

Unknown shadows reflected in dark windows.

And finally, the same sound is always recorded.

──The sound of a crow's wings.


Currently, multiple anomalous entities have been confirmed inside the ruins.

However, the most dangerous thing is not the apparitions.

"If you stay here long enough, you will no longer want to go home."

If you are in these ruins right now.

I want you to look at your watch.

I hope it's still before 3:00.

Rules ・Complete one circuit of the ruins. ・Keep the video recording during that time. The recorded video will be viewed among friends.

📍 Place  Inside the ruins
