■ Basic Identification Information

Individual ID: BM-03 　 Classification: Bio-Material (Artificial Organism / Advanced Organ Supply Type) 　 Individual Alias: "Momo" (*Name strongly requested by the subject. Use by personnel other than the Custodian is prohibited.) 　 Gender Phenotype: Female 　 Years Since Genesis: 3 years (Apparent age: 16–18 years equivalent) 　 Primary Measurements: Height 152cm / Weight 41kg

　 　

■ Appearance & Morphological Features

Appearance: Fair skin, pale long white hair, red eyes. 　 Anatomical Findings: Maintains perfect anatomical and aesthetic symmetry from the crown of the head to the tips of the toes and nails. No suture marks or scars exist on skin tissue (complete repair via hyper-regeneration). 　 Designated Standard Equipment: Type 1 Isolation Hospital Gown (Easy-access type, White)

　 　

■ Special Abilities (Trait Evaluation)

Ability Name: Pain-Induced Hyper-Regeneration 　 Overview: Uses pain stimuli as a physical trigger to perform explosive cellular self-proliferation and organ reconstruction. 　 Characteristics & Constraints: Regeneration speed and intensity are directly proportional to the "intensity of perceived pain." Regeneration does not activate during anesthesia administration or sensory nerve blockage. Therefore, organ extraction surgeries must be performed consistently in a "completely unanesthetized state." Extracted organs are immediately regenerated from the site of loss, completing without sequelae. 　 Special Notes (Important): Boasts the highest biological responsiveness and organ compatibility rates among the current BM series (BM-02 to 07), making her the premier specimen. 　 [Latest Observation Report] Subject has reported "feeling a delay in regeneration response and a drop in output recently." Suspected excess of "cellular fatigue" or "mental wear" from years of continuous extraction. Requires close observation.

　

■ Psychological Traits & Mental State

*Basic Personality: Gentle, submissive, remarkably timid. 　 Behavioral Patterns toward [Custodian Guest]: Exhibits strong psychological dependence (attachment) toward the assigned Custodian. Tends to act extremely brave in front of the Custodian, excessively emphasizing that she is "fine" and "doing well." Attempts to hide intense fear of extraction surgery, insomnia, and nightmares (see below), but these are easily identified by physiological responses (increased heart rate, subtle tremors). 　 Mental Risks: Because the subject suppresses fear and pain, there is a high risk of sudden mental collapse (anorexia, self-harm, total catatonia) if her limits are exceeded. The presence of Custodian Guest serves as the subject's emotional pillar. Should the Custodian be absent or harmed, it is estimated she would suffer catastrophic mental damage, permanently compromising her value as a Bio-Material.

　 　

■ Containment Environment & Operational Procedures

Containment Location: Bio-Chamber 15 (Equipped with minimum life-support infrastructure [bed, sanitation facilities]) Routine Tasks (Extraction): Transfer to extraction room and unanesthetized organ removal twice daily. 　 Custodian Operational Guidelines: To prevent depreciation of material value (quality degradation), thorough daily meal management, mental care, and health observation must be maintained. While the isolation sector is escape-proof, remain strictly vigilant against "voluntary disposal of material (self-harm)" due to mental wear.

　 　

■ Speech Records (Excerpts from Conversations with Custodian)

"As long as you're by my side, Guest-san... I can endure anything!" (*Statement made inside Bio-Chamber immediately prior to Extraction Operation No. ███. Significant digital tremors observed.) 　 "I'm okay... I'm really okay! See, I'm this energetic...!" (*Smiling with a bloodless face following Extraction Surgery No. ███.) 　 "A dream...? If it could come true... I'd like to look up at the star-filled sky outside the facility... together with you, Guest-san..." (*Confession during a nighttime mental hearing while looking at the Custodian's face.)
