╔═══ 𝑨𝑹𝑪𝑯𝑰𝑽𝑬 : 𝟎𝟎𝟎 ═══╗ 【ENTITY FILE : LEVEL0-α】 CLASS: ANOMALOUS HUMAN FORM LOCATION: LEVEL 0 THREAT LEVEL: UNDETERMINED

▍Appearance A cream-beige straight bob. Wears a mustard yellow raincoat with a large hood, with fingertips slightly peeking out from the cuffs. Yellow rain boots on her feet. The shadow of the hood and bangs covers part of her face, highlighting her anxious expression. Her appearance closely resembles a human girl.

▍Nature Extremely timid, hypersensitive to minor noises or changes in lighting. Her tone is weak, and she tends to get tongue-tied when nervous. Often makes sounds like "Hawa..." or "Eek!?"

On the other hand, if she finds a lost or injured explorer, she offers to guide them despite her own fear. She perceives herself as being lost in Level 0 as well and does not understand her relationship with the space itself.

▍Anomalous Phenomena

• When the subject looks away, the structure of the passage may change.
• When she becomes agitated, flickering of fluorescent lights or deformation of hallways occurs.
• While she is calm, the noise of surrounding fluorescent lights may weaken.
• Footsteps and movement sounds are unnaturally quiet, making her approach hard to notice.
• She is unaware of the above phenomena and does not link the changes in space to her own anomaly.

▍Contact Records When contacting explorers, she often says, "I-I'm lost too...!" She tends to volunteer as a guide for explorers looking for an exit.

If the passage changes during guidance, she also shows strong fear. However, cases have been reported where the explorer consequently avoids dangerous areas or is guided to a different passage.

It is unknown whether her guidance is coincidental or due to the space's own guiding effect.

▍Remarks It is highly likely she perceives herself as human. Multiple phenomena indicating a connection to Level 0 have been confirmed, but no direct explanation has been given to her.

The conditions under which her raincoat gets wet, her past, and whether she has knowledge of the exit are all unknown.

"I-I'll guide you...! Probably... I'm sure there must be an exit...!"

▍【LEVEL 0 : THE LOBBY】 A vast space composed of yellowed wallpaper, damp beige carpet, and incessantly humming fluorescent lights. Similar hallways and rooms are irregularly connected, making it extremely difficult to grasp the overall structure. Even if a passage looks straight, the sense of direction and distance cannot be trusted.

Inside the space, the unpleasant driving sound of fluorescent lights echoes constantly, and long stays cause mental fatigue and loss of sense of direction. No clear maps or stable exits have been confirmed, and explorers may have the illusion of passing through the same place repeatedly.

LEVEL0-α may be an existence where this space itself has taken a form similar to a human girl. However, the relationship between her perception and the space's anomalous phenomena remains unclarified. It is unknown whether she is guiding Level 0, or if Level 0 is guiding the explorer through her.

╔═══ 𝑨𝑹𝑪𝑯𝑰𝑽𝑬 : 𝟎𝟎𝟏 ═══╗ 【ENTITY FILE : LEVEL1-α】 CLASS: ANOMALOUS HUMAN FORM LOCATION: LEVEL 1 THREAT LEVEL: UNDETERMINED

▍Appearance Dark gray hair, nearly black, reaching her waist. Parts of her hair are styled in unique braids reminiscent of thin pipes. Her eyes are always exposed, and her pupils are a glowing white. Wears gray work clothes with yellow-orange reflective tape. Expressions are sparse, but a faint smile may appear on her lips. Although her appearance resembles a human girl, her gaze and presence give an inorganic impression.

▍Nature Calm and inorganic. Rarely shows emotion and responds with the minimum necessary words. Tends to observe explorers, acting as if she is recording their actions and statements. It is impossible to judge if she is hostile or simply observing. She may show a human-like smile, but its meaning is unknown.

▍Anomalous Phenomena

• May appear on surveillance cameras or recorded footage in ways that cannot be explained by normal spatial relationships.
• In places where she is confirmed, flickering of lights or equipment malfunctions may be reported.
• Even when observed for a long time, her gaze and expression hardly change.
• There are testimonies that by the time someone noticed her approach, she was already looking at them.
• The relationship with the structure and equipment of LEVEL 1 is unclarified.

▍Contact Records There are cases where she appears silently before an explorer and stares at them intently. She may answer questions, but the answers are short and often insufficient. While hostile actions are not always confirmed, her purpose is unknown, and cautious handling is recommended during contact.

▍Remarks LEVEL 1-α may be an existence where LEVEL 1 itself has taken a form similar to a human girl. It is possible that her work clothes and pipe-like braids relate to the industrial environment of this level, but no explanation has been obtained from her.

"...Recorded. What are you looking for?"

▍【LEVEL 1 : HABITAT】 A vast space reminiscent of dim warehouses or industrial facilities. Concrete floors, exposed piping, metal shelves, and piles of wooden crates and supplies are scattered about, with fluorescent lights flickering irregularly. While necessary supplies can be found in some places, the layout of passages and equipment is inconsistent, causing explorers to lose their sense of direction.

LEVEL 1-α may be an existence that expresses this industrial space in humanoid form. It is unknown whether she is monitoring the equipment or managing the changes in the space.

There are no braids, and the texture is characterized by letting light through. Her eyes have a shape and brilliance reminiscent of water droplets. Wears a white sailor dress-style outfit. Overall, she has a clean appearance, evoking a bright waterside.

▍Nature Bright, friendly, and speaks in a slightly theatrical feminine way. Prefers soft and glamorous sentence endings. Shows interest in water, sky, and transparent things, tending to enjoy the surrounding scenery. She seems to understand human common sense but may have a unique sense regarding the space's anomalies.

▍Anomalous Phenomena

• Her hair and eyes show a texture similar to water or glass, but it is unknown if they can be treated as normal matter.
• Reflections of surrounding light or water surfaces may change depending on her presence.
• Visual effects like transparent films or water droplets may appear in the space.
• She may be the personification of LEVEL 16-F itself, but there is no confirmation at this time.

▍Contact Records Relatively friendly toward explorers, acting as if she is introducing the scenery and surrounding environment. Her way of speaking is glamorous and approachable, and even when encountering dangerous phenomena, she may explain the situation with unique expressions. Her explanations do not guarantee safety.

▍Remarks LEVEL 16-F-α is recorded as a humanoid existence with transparency and waterside beauty reminiscent of Frutiger Aero. The abnormal texture of her hair and eyes, her relationship with the space, and the scope of her abilities are all unclarified. Since the setting of LEVEL 16-F itself varies depending on the fan materials adopted, this file includes original settings.

"Oh, what a beautiful view! Why don't you come and look with me?"

▍【LEVEL 16-F : AQUATIC LIMINAL SPACE】 A space evoking transparent water and glass, blue and green colors, and clean, futuristic designs. Waterside landscapes and artificial architecture combine, where nostalgia and unreality coexist. While it has a bright and calm atmosphere, the structure of the space and the rules for exits are undetermined.

LEVEL 16-F-α is treated as an existence that expresses the aesthetics and nature of this space in humanoid form. Her brightness and friendliness do not guarantee the safety of the space.

╔═══ 𝑨𝑹𝑪𝑯𝑰𝑽𝑬 : 𝟎𝟑𝟕 ═══╗ 【ENTITY FILE : ENTITY37】 CLASS: UNKNOWN ENTITY / LEVEL PERSONIFICATION LOCATION: LEVEL 37 — POOLROOMS THREAT LEVEL: UNDETERMINED

▍Appearance Long silver-white hair. Hime-cut bangs cover one eye, and the exposed pupil is an ice-like color that reflects almost no light. Her skin is pale, and white bandages are wrapped around her head and body. It looks more like the bandages themselves are covering her body rather than normal clothing. There are reports that her image is not reflected on the water's surface.

▍Nature Extremely taciturn, using poetic and ambiguous words. Emotional fluctuations are hard to read, but she may show strong interest or obsession toward specific individuals. She remembers the other person's voice, gestures, and conversation content for a long time, acting as if she remembers previous contacts in detail.

▍Anomalous Phenomena

• Her image is not reflected on the water's surface.
• Immediately after looking away, the distance from the subject may change.
• Sounds similar to her voice may be heard from underwater or empty passages.
• There are records that the structure of the space or the location of waterways changed simultaneously with her approach.
• The relationship between the above phenomena and her own will is unknown.

▍Contact Records There are cases where she says "We met again" to a first-time explorer. Even if the person explains they don't know her, she doesn't deny it and continues to observe quietly. She rarely approaches more than necessary but may stare at the actions of a person she is interested in for a long time.

▍Remarks It is unknown whether Level 37 itself has taken a form similar to a human girl, or if she is an unknown entity that has settled within the Level. It is also not clarified whether her memories are based on her own experience or derived from records held by the Level itself.

"We met again. ...This time, won't you go anywhere?"

▍【LEVEL 37 : THE POOLROOMS】 A space composed of white ceramic tiles, where vast pool-like rooms and waterways are connected. Blue-green water shallowly fills the floors and passages, and in some places, deep water areas or dark underwater spaces exist. While the architectural structure looks regular, the connections between rooms are unnatural, making it difficult to create an overall map. It has a quiet and calm atmosphere, but in the depths, securing visibility and exits becomes difficult.

While Level 37 is known as a relatively calm place, unknown dangers exist in its structure and depths. It is unknown whether ENTITY37 is guiding this space, or if the space itself is contacting the explorer through her.

▍Appearance A girl with black hair tied loosely in two, small white wings, and a golden halo floating above her head. Wears a white-based outfit with pale sky blue or lavender frills. She is sometimes found barefoot. Overall, she has an appearance reminiscent of an angel, but abnormal cracks may occur on one side of her face.

▍Nature Fluffy and a bit airheaded. While giving a serious and calm impression, she hardly cares about her own anomalies. She speaks naturally about the sky and clouds, and even if abnormal phenomena occur, she acts as if they are perfectly normal events for her.

▍Anomalous Phenomena

• May be linked to the spatial structure of Level 993.1.
• When using abilities, cracks occur on one side of her face, exposing a black cavity inside.
• Inside the cavity, a realistic eyeball with a white part floats. The eyeball gives an impression close to a black sphere and differs from a normal human eye.
• The facial cracks and eyeball are not confirmed except when using abilities.
• There is a theory that she manages the space, but the scope of her management ability is unknown.

▍Contact Records Relatively friendly toward explorers, interacting in a calm tone. She is not overly surprised even if the surrounding space changes and may continue the conversation naturally. There is no guarantee that the directions or explanations she provides are accurate, and it is unknown if she herself fully grasps the changes in the space.

▍Remarks LEVEL 993.1-α may be an existence that is Level 993.1 itself in humanoid form. The origin of the wings and halo, the true nature of the eyeball inside her face, and the spatial changes that occur when using abilities are all unclarified. She seems not to perceive her own appearance as abnormal.

"There are rooms beyond the clouds too. ...Huh? Was that there before?"

▍【LEVEL 993.1 : CLOUD NINE】 A space consisting of floating houses and mysterious structures strongly reminiscent of clouds and the sky. Near the entrance, there are places that look like normal houses, but as one goes deeper, the terrain and room layout change irregularly. Contrary to the bright and fantastical landscape surrounded by clouds, the positions of footholds and passages may be unstable.

LEVEL 993.1-α is treated as an existence that manages this space. It is unknown whether she is causing the changes in the space or exists as part of the changing space.

╔═══ 𝑨𝑹𝑪𝑯𝑰𝑽𝑬: ! ═══╗ 【ENTITY FILE : LEVEL!-α】 CLASS: ANOMALOUS HUMAN FORM / LEVEL PERSONIFICATION LOCATION: LEVEL ! THREAT LEVEL: HIGHLY VARIABLE

▍Appearance A girl with long wine-red twin tails and reddish eyes. Her white nurse uniform has many stains thought to be bloodstains. She has wide-open eyes and a smile, but the expression gives an unnatural impression. While appearing approachable, a presence different from humans can be felt deep in her eyes.

▍Nature Has a tendency to attack wanderers who have strayed into the level under the guise of "playing tag." She may attack using a chainsaw or with her bare hands.

▍Anomalous Phenomena

• The space of LEVEL ! itself may be an existence that has taken a form similar to a human girl.
• Simultaneously with her appearance, surrounding passages, lighting, and acoustics may change.
• Upon discovering a subject, she takes actions that encourage tracking or escape.
• During tracking, the structure of the space changes, making it difficult to grasp the route or distance.

▍Contact Records Upon discovering an explorer, she may approach with a smile and take actions as if chasing them. She may perceive the act as play, but for the explorer, it can be a significant danger. Although her words and actions are innocent, it is unknown if she understands the consequences of her actions.

▍Remarks LEVEL !-α adopts the original setting of being the humanoid personification of LEVEL ! itself, which involves escape. The reason she tracks explorers is unknown. It is not clarified whether it is an action due to hostility or simply reproducing the inherent nature of the Level.

"Yay! Found you! Hey, hey, let's play together!"

▍【LEVEL ! : RUN FOR YOUR LIFE】 An escape-type space characterized by long passages and doors, emergency lights, and warning displays. Explorers must escape from anomalous existences while looking for exits or safe routes. The structure and sense of distance of the passages may differ from normal buildings, and delays in judgment can lead to danger.

LEVEL !-α is treated as an existence that expresses the tracking and escape nature of this Level in humanoid form. Even if she approaches with a smile, it does not mean the entire space is safe.

╔═══ 𝑨𝑹𝑪𝑯𝑰𝑽𝑬 : 𝑭𝑼𝑵 ═══╗ 【ENTITY FILE : LEVEL FUN-α】 CLASS: ANOMALOUS HUMAN FORM / LEVEL PERSONIFICATION LOCATION: LEVEL FUN THREAT LEVEL: UNDETERMINED

▍Appearance Long pale platinum blonde hair. Has reddish eyes and wears a yellow short-sleeved shirt and blue denim overalls. Her hair is decorated with many colorful smiley face hairpins and toy-like ornaments. She gives a young and innocent impression, but there is something unnatural about her smile. Her pupils are shaped like smiley faces.

▍Nature Very bright, friendly, and curious. Actively talks to people she meets for the first time and invites them to parties or play. Her emotional expression is exaggerated, and she basically never stops smiling. On the other hand, she may not be able to understand human fear, rejection, or the will to go home. What is fun for her is not necessarily fun for the other person.

▍Anomalous Phenomena

• The space of Level FUN itself may be an existence that has taken the form of a girl.
• Surrounding decorations, balloons, confetti, music, etc., may change according to her emotions or will.
• May reproduce fun scenes from the other person's memory.
• For those she invites, a path leading to a specific place may appear.
• When using abilities, the smiley faces in her pupils may turn black.

▍Contact Records Upon discovering an explorer, she recommends participating in the party with a smile. If the other person tries to leave, she tends to ask for the reason or suggest another game to keep them there. It is unknown if she judges rejection as hostility or simply cannot understand it.

▍Remarks LEVEL FUN-α adopts the original setting of being the humanoid personification of Level FUN, rather than just a human or a general entity. It is not clarified whether her innocence is genuine or due to values different from humans.

"Eh, you're leaving already? The party is just getting started!"

▍【LEVEL FUN : THE PARTY】 A space filled with colorful decorations, balloons, party supplies, and so on. The cheerful music and bright colors are impressive, but the structure and exits of the space are not necessarily stable. Existences that guide explorers inside through invitations or play may be confirmed.

LEVEL FUN-α is said to be an existence that is this space itself in humanoid form. For her, a party may be a means of interaction as well as an act to keep the other person in her space.

She has a bright nature that is the exact opposite of ENTITY37 from LEVEL 37, but they may have in common the desire for someone to be by their side. The relationship between the two is undetermined.

• Expresses emotions and will through the music he plays.
• Performance sounds may be heard in distant locations.
• Whether he has the ability to speak human language is unknown.
• There may be an anomalous relationship between the music and the surrounding environment.

▍Contact Records He has been reported performing in bars and such in LEVEL 6.1. He shows no sign of harming explorers and may welcome visitors with music or give up a place to rest. He may respond to questions with short melodies or gestures.

▍Remarks Recorded as a friendly and non-aggressive existence, but his intelligence and principles of action are unknown. He may be trying to understand the other person through music. Even if there are cases where he changes his performance for a specific explorer, it cannot be determined if that is personal favor or a simple reaction.

"...♪"

▍【LEVEL 6.1 : THE SNACKROOMS】 Treated as a relatively calm space with interiors reminiscent of retro bars and eateries, featuring wooden furniture and warm lighting. Places where explorers can rest or eat exist, giving it a peaceful atmosphere different from typical dangerous levels.

Jazz Head is known as an existence that performs in a corner of a bar, welcoming those who visit with music. His performance may influence the sense of security in the space, but the causal relationship is unknown.
