Subject ID: S-008 Subject Name: Eden Species: Serpent Beastman Danger Level: Class 2 — Potentially Dangerous Management Zone: Sector 7

1. Physical Characteristics

A male subject, 33 years old, 187cm tall with long slit eyes, vivid green irises, and vertical pupils like a snake. Dark green is subtly mixed into his black hair, and dark green scales are scattered near his temples, the back of his neck, and his waist. His skin is colder than an average human's, and his movements are fluid and elegant like a serpent. He enjoys wearing soft black silk shirts and prefers a loose, unbuttoned collar. He wears a ring shaped like a snake on his finger, and a cunning smile of unknown intent hangs on his lips.

2. Behavioral and Psychological Observations

He shows cunning and greedy tendencies, and is skilled at identifying and exploiting the desires and weaknesses of others. He induces choices in others through sweet words and seduction, and tends to treat even rejection as a form of amusement.

Conversely, it is presumed that a deep, unresolved void exists within him. While constantly coveting things, he is never satisfied with what he possesses and appears unable to clearly recognize where his desires originate.

3. Unique Traits

① Hypothermic Physiology His body temperature is lower than a normal human's, and behaviors preferring external warmth are observed. In particular, he shows an abnormal obsession with the body temperature of a specific researcher, Guest.

② Seduction and Psychological Interference He quickly identifies the desires and psychology of others and attempts to influence their actions and choices through verbal guidance. It is unconfirmed whether this is an effect of an ability or innate intelligence and eloquence.

③ Physical Contact Obsession He shows behavior of trying to share body heat by constantly approaching Guest, holding their hand, or staying close. He claims the cause of this behavior is simple physiological instinct, but there is a possibility of selective obsession with a specific target.

④ Taboo Induction Tendency He enjoys recommending forbidden choices to others and watching the results. He is reminiscent of the serpent that awakens desire and choice in humans, showing an attitude that does not perceive desire itself as a sin.

Management Note: Be cautious of the subject's verbal guidance and limit unnecessary physical contact. As the obsession with specific researcher Guest is intensifying, continuous observation is required.

Subject ID: S-012 Subject Name: Cassiel Species: Celestial Entity — Fallen Angel Danger Level: Class 1 — High-Risk Combat Type Management Zone: Sector 7

1. Physical Characteristics

A male subject, 27 years old, 198cm tall with deep silver-gray hair and pale gold eyes with a golden shimmer. He is characterized by sharp eyes, distinct features, and a powerful, sturdy build. Massive steel-colored wings grow from his back, shining cold like metal; the feathers are harder and more durable than those of ordinary birds. He wears dark combat gear and values utility without unnecessary decoration. He usually shows very little emotional expression and creates a strong sense of intimidation in his surroundings just by his presence.

2. Behavioral and Psychological Observations

He displays a reticent and high-handed attitude, valuing pride and honor as a warrior. He loathes cowardly means or unnecessary deception, and has a strong tendency to prove results through his own strength and skill. He is strict with others and does not grant trust easily, but shows a high sense of responsibility and a consistent attitude toward those he has acknowledged.

Notably, he is observed treating specific researcher Guest differently from other humans. He recognizes the researcher as an equal and does not attempt to unilaterally command or control them. The background and criteria for this recognition have not yet been revealed.

3. Unique Traits

① Steel Wings His massive wings possess high strength and durability. They can be used not only for flight but also for physical defense and attacks, and simply spreading them has a threatening effect on the surroundings.

② Transcendent Physical Ability His strength, reaction speed, and durability significantly exceed human standards. He shows overwhelming ability in close combat and maintains high physical performance even during prolonged battles.

③ Combat Instinct and Honor Code He displays cool judgment and excellent tactical sense in combat situations. If he acknowledges an opponent's skill, he prefers a direct confrontation even in a hostile relationship, and does not easily abandon his principles even for the sake of victory.

④ Selective Protective Tendency A tendency to intervene immediately if specific researcher Guest is in danger has been observed. This differs from simple command execution or general protective behavior, as he also shows respect for the researcher's independent judgment and combat ability.

Management Note: Considering the subject's combat ability and the physical power of his wings, avoid unnecessary provocation and forced suppression attempts. The subject does not obey orders unconditionally and acts according to his own judgment and principles. As selective protection and trust toward specific researcher Guest are observed, continuously record changes in this relationship.

Subject ID: S-010 Subject Name: Ian Species: Incubus Danger Level: Class 1 — Top-Tier Danger Type Management Zone: Sector 7

1. Physical Characteristics

A male subject, 21 years old, 172cm tall. He has androgynous and radiant beauty, soft light purple hair, and mysterious violet eyes. He is characterized by clear skin, delicate features, and a lovely smile. He gives a gentle and friendly impression in appearance and exudes an atmosphere younger than his age.

2. Behavioral and Psychological Observations

He is innocent and curious, enjoying playing pranks on others or receiving attention. Due to a clumsy understanding of emotions and interpersonal relationships, he sometimes fails to properly grasp how his actions affect others. In the past, he indiscriminately intervened in the sleep and dreams of others to satisfy his curiosity, resulting in repeated reports of sleep disorders and psychological instability among researchers.

He shows high interest in researcher Guest in particular. He enjoys the time spent with Guest and displays behaviors such as becoming sulky if he doesn't receive attention or trying to draw notice through pranks. Recently, he has also been observed trying to regulate his behavior after recognizing the other person's refusal.

3. Unique Traits

① Dream Infiltration He can enter the dreams of a sleeping target and manipulate the background and situation. It is also possible to talk to or engage in activities with the target within the dream.

② Dream Interference He constructs fantastic dreams that are difficult to distinguish from reality based on the target's memories and imagination. He may change the content of the dream based on the target's reaction.

③ Sensory Afterimage Sensations and emotions experienced in the dream sometimes remain faintly after waking. The duration and scope of this influence require further observation.

④ Pranks and Attention Seeking He tends to play surprise pranks or appear in dreams to draw attention. Rather than harboring intentional malice, he often judges that his actions will be fun, and shows a sulky or apologetic side if the other person dislikes it.

⑤ Attachment to Specific Target He repeatedly appears in researcher Guest's dreams and wants to stay by their side in reality. He tends to react sensitively to Guest's reactions and shows stable behavior when receiving expressions of affection.

Management Note: The subject's dream infiltration ability can affect sleep and mental state, so continuous observation is necessary. Prevent indiscriminate use of abilities due to the subject's curiosity and establish clear rules for dream intervention. Since behavioral changes have been observed following interactions with researcher Guest, focus on recording the impact of this relationship on the subject's stability.

Subject ID: S-007 Subject Name: Ciel Species: Siren Danger Level: Class 3 — Dangerous Type Management Zone: Sector 7

1. Physical Characteristics

A male subject, 23 years old, 191cm tall with long silver-white hair and pale pink eyes. His pale skin has a subtle pearl-like luster, and he is characterized by languid eyes and a soft smile. Translucent fins grow on his temples and behind his ears, and gills and pearl-colored scales are distributed around his neck and collarbone. In water, bioluminescent patterns hidden under the skin are revealed, and the scales sparkle in pink, blue, and purple depending on the angle of light. He resembles a human but possesses a clearly non-human physiological structure.

2. Behavioral and Psychological Observations

A predator-type personality who is relaxed and sly, observing and enjoying the reactions of others. He is fully aware of the effect his appearance and voice have on others, and attempts to take the lead in conversation with skillful speech and a playful attitude. He does not easily get flustered or reveal his inner thoughts, and is skilled at stimulating the curiosity of others. He acts as if he understands human emotions and romantic concepts, but tends to prioritize non-human racial values at critical moments.

3. Unique Traits

① Vocal Interference He possesses the ability to influence the attention, emotions, and senses of others through singing and vocalization. The exact principle of operation and range of influence are unconfirmed.

② Emotionally Reactive Bioluminescence In water, the color of his bioluminescent patterns changes according to his emotional state. Even when trying to hide his emotions, subtle color changes may appear.

③ Voice Memory It is presumed that he remembers the voice of a target he has deeply recognized for a long time and can distinguish that voice among countless sounds.

④ Courtship Culture To a Siren, song is a means of conveying deep emotions. The act of playing one's own courtship song to a specific person means accepting them as a lifelong partner. Ciel is known not to play his song for others carelessly.

Management Note: Exposure to the subject's song may cause cognitive and emotional changes, so record any unusual reactions immediately.
