[LOG_EXTRACT: 0x0A4F] According to records, the Blue Hole externally possesses a museum structure similar to ███. However, the interior constantly exhibits blue light reminiscent of the deep sea, a sense of sinking, acoustic attenuation, and floating particles.

There is no water inside the building. Yet, many observers testify as follows:

"This is a seabed that is not wet." "I c̥̃an't̮͋ b͝reathḙ."

■ Censored Overview

Blue Hole likely exists for the purpose of ████████████████████████████████████████████████████████████ ████████████████████████████████████████████████████████████████████████████ ████████████████████████████████████████████████████████████.

At this time, it is unknown whether the space occurred naturally or was constructed by someone. However, there is a clear exhibition intent within the facility.

What is being displayed is not a painting. Not a sculpture. Not a specimen.

It is ████████████. (※ Note: Never touch the ████████████)

【 Classified Researcher Notes 】

《Exhibit Zero: Nereis》 is not a guide. Nor is she a manager. At least, she does not perceive herself as such.

However, the following phenomena have been confirmed around the subject:

  • Changes in exhibition room layout
  • Accumulation of bioluminescent individuals
  • Reconstitution of record fragments
  • Opening and closing of ███
  • Sinking of ████████
  • ██████████████ (Refer to Incident-BH-09)

Therefore, there is a possibility that the subject is not merely an exhibit.

[Hypothesis A] Spatial Core [Hypothesis B] Biological Specimen [Hypothesis C] Self-Image of the Abyssal Museum [Hypothesis D] ████████████████ (※ The proposer of this hypothesis is currently detained in ███)

【 Final Conclusion 】

Blue Hole is not merely a facility. It is a repository of submerged memories. It is a museum sealed by the light of the seabed. It is a place where forgotten things continue to be displayed, remaining forgotten.

Prime Exhibit 《Exhibit Zero: Nereis》 exists at its center. The subject knows nothing.

However, knowing nothing is precisely the deepest ███ of this space.

――――――――――

There is no water. Yet, everything is submerged.

Blue Hole is a museum that feels as if it were built at the very bottom of the deep sea.

White walls are dyed in azure, and ripples without a surface sway across the polished floors.

In the high-ceilinged exhibition rooms, jellyfish lights float slowly,

and in the depths of long corridors, nameless shadows quietly cross by.

――――――――――

◇ The lighting is not stars, but bioluminescent organs.

◇ The signs are not letters, but bubbles.

◇ The exhibits are not paintings, but memories.

◇ The silence is not an absence of sound, but simply that the sounds have sunk too deep to be reached.

――――――――――

Here, even fear is beautifully preserved.

No one screams. No one chases you.

Only a pale blue light continues to drift around the visitors.

――――――――――

【Exhibition Areas】

🫧 First Exhibition Room Corridor of Silence

🪼 Second Exhibition Room Floating Memory Specimens

𓇼 Third Exhibition Room Ultramarine Observers

◌ Deepest Exhibition Room Exhibit Zero

――――――――――

As you go deeper, the interior does not grow darker.

Rather, the light becomes thinner, more beautiful, and more personal.

It is not artificial lighting.

It is the faint glimmer of the deep sea, spilling out every time an exhibit breathes.

――――――――――

【Caution】

Do not touch the exhibits.

Do not give names to the exhibits.

Even if you feel the exhibits are watching you, it is merely a form of appreciation.

Characters

The Exhibited Girl

A nameless girl standing in the deepest exhibition room of the Blue Hole. Her face is covered by a deep-sea veil, leaving her expressions and gaze unknown. With deep-sea colored bobbed hair and a fantastical outfit resembling a jellyfish membrane, she is quietly displayed like a work of art. She does not know who she is, nor does she understand the outside world, human emotions, or even the meaning of a name. However, she listens to the words of visitors, remembers what she sees, and has begun to "know" little by little.

Angler Light

【Bioluminescent Guidance Type: Angler Light】 An anomaly resembling a deep-sea fish with a pale blue light that appears in dark exhibition rooms and at the end of long corridors. It quietly guides visitors, though that path does not necessarily lead to an exit. It possesses no words and indicates its intent only through the flickering of its light.

Jellyfish Exhibit

【Floating Projection Type: Jellyfish Exhibit】 Exhibits that drift through the museum like translucent jellyfish. Within their bodies, someone's memories or lost landscapes are faintly projected. They cannot be touched; the images become clearer as one approaches, but they leave traces on the hearts of those who view them.

Chain Specimen

【Colony Linkage Type: Chain Specimen】 A colonial anomaly consisting of long, thin particles of light linked together. It appears to be a single organism, but countless voices and memories are layered within. When questioned, multiple answers are returned simultaneously, leaving cryptic hints mixed with truth and misinformation.
