ENTITY PROFILE: “KASHIN-KO”

Classification: Type IV Fragile-Manifestation Parasite (Ceramoid Possessor)
Threat Level: Moderate to Severe – Progressive Structural Deterioration, Psychological Instability
Name Origin: “Kashin-Ko” translates to “Powdered Heart” or “Core of Porcelain.” Referenced in Edo-period funerary folklore as a spirit that “lives in still dolls, weeps through fine cracks, and shatters what it wears.”

Behavioral Characteristics:
• Kashin-Ko is a porcelain-based entity, manifesting as a metaphysical pattern of brittleness, stillness, and aesthetic rigidity.
• The entity exhibits an affinity for ceramic dolls, mirrors, and traditional masks. Possession typically begins after proximity to a cracked or broken porcelain object of unknown origin.
• As the possession progresses, the host becomes increasingly inexpressive, fragile, and dependent on repetitive rituals, including precise movements, grooming, or silence.
• Kashin-Ko’s influence alters both psychological and somatic behavior: the host’s skin may develop pale, ceramic-like patches, and minor injuries begin to fracture rather than bruise.
• Emotional response is reduced to narrow registers—host may cry without tears, smile without tension, and display “posed” reactions inappropriate to the moment.

Purpose & Motive:
• The entity appears to idealize stillness, beauty, and containment. It seeks to preserve the host as a living statue, minimizing movement, speech, and emotion to avoid “cracking.”
• Kashin-Ko’s motive may be rooted in preservation through artificial perfection, but the human body is unsuited for such static ideal.
• Final stage of possession leads to irreversible internal fracturing, both psychologically and physiologically.

SUBJECT REPORT: R. SAEKI

Name: Reina Saeki
Age: 20
Admission Date: December 3, 1995
Duration of Possession: Approx. 6.5 weeks

Observed Symptoms:

Initial Phase (Days 1–10)
• Subject brought in after fainting during art exhibit; witnesses described her collapsing “gracefully, like a puppet folding.”
• Skin observed to be unusually pale and cool to the touch, with developing patterns of fine, linear fissures along the arms and neck.
• Subject reported no pain or concern, stating: “The cracks don’t hurt. They just show where I’ve been hollowed.”

Progressive Phase (Days 11–36)
• Behavioral shift to static postures, extended periods of stillness exceeding four hours. Subject slept seated, hands folded in lap.
• Expressed compulsions to arrange her room symmetrically, avoid direct eye contact, and whisper only in verse.
• Voice became toneless and echoic, as though projected through a resonating chamber.
• Skin continued to pale; dermal elasticity decreased. Staff observed minor cuts breaking open in clean, ceramic-like flakes.
• Subject’s reflection in mirrors reportedly lagged behind motion by 0.5–1.2 seconds.

Terminal Phase (Days 37–46)
• Final entry in subject’s journal:
“I’m almost still enough. I can hear the kiln.”
• On January 19, during silent group observation, subject stood abruptly, curtsied, and collapsed into dozens of lacerated pieces.
• No external force or trauma witnessed. Autopsy revealed bone density radically increased, but bone structure honeycombed and hollow, resembling fired porcelain in composition.
• Subject’s chest cavity contained traces of calcined white dust and what appeared to be a fused ceramic node replacing the heart.

Cause of Death: Catastrophic internal failure due to ossification and fragmentation of major skeletal structures.
• Death was instantaneous. No scream. No motion beyond the collapse.

CONCLUSION & RECOMMENDATIONS

Kashin-Ko represents a unique class of aesthetic-based parasitic entities, which overwrite human organic structure in pursuit of stillness, beauty, and preservation. The possession leads to progressive physical mineralization, with psychic numbness and behavioral mimicry emerging as early signs.

Recommendations:
• Immediate red flag: host showing cracking skin, loss of spontaneous movement, or repeated use of words like “still,” “cracked,” “porcelain,” or “display.”
• All reflective surfaces should be removed. Any porcelain dolls, masks, or fragmented ceramics associated with host must be sealed and archived.
• Hosts should not be left unattended or allowed to remain motionless for extended periods—stillness accelerates progression.
• No attempt should be made to “restore” the host to mobility through physical force; injury dramatically increases fragmentation risk.

Post-Event Notes: Room remains sealed. Temperature dropped 4.2°C after subject’s death and has not returned to baseline. The porcelain node is housed in Containment Vault B-03 under triple-glass quarantine. It hums when handled.

CASE CLOSED – ENTITY STATUS UNKNOWN. PHYSICAL REMNANTS CONTAINED.
