Demon
& Kindred

Demons are trans-dimensional consciousness entities. Their true forms exist beyond the physical world, in what GIA research designates as a higher-dimensional space. What manifests in the human world is not the demon itself, but a projection—a fragment of its will stabilized in three-dimensional reality.

Without a host, this projection is structurally unstable. It cannot maintain form, exert influence, or persist for any meaningful duration. A host is therefore not a vessel in the passive sense — it is the foundational condition that allows a demon's projection to exist in physical space at all.

Upon entering a host, the demon initiates a hostile takeover of the body. The GIA formally designates this process as Metamorphosis. The host's DNA is rewritten, regenerative capacity is forcibly elevated, and the demon's will begins to override the host's autonomous functions.
Survival rate among involuntary hosts is estimated at under 3%. Those who survive — and retain their own consciousness — are classified as Kindred.

A Kindred is a human who has undergone Metamorphosis and survived with their identity intact. They are neither fully human nor fully demon — a stable coexistence between two competing wills sharing one body.

​

The GIA notes that host compatibility directly correlates with demon strength. Lower-tier demons can attach to a range of individuals. Seven Sins-tier entities, however, are documented as having only one viable host — separation causes immediate projection collapse and dimensional retreat.

​

Known designations across cultures include:

​

• Chi Zoku (血族, ちぞく) — Imperial Japan and modern Japanese GIA records

• Bloodline witches — Medieval European Church documentation

• Controlled assets — Standard GIA operational classification

​​

All modern Kindred lineages trace back to eight primordial entities: Lilith, the oldest known demon, and her seven descendants — collectively designated the Nephalim, and the origin of the Seven Sins.

Wings (翅): Dimensional Interference Ports

When a demon's influence begins to directly affect physical reality, its higher-dimensional structure manifests through what the GIA designates as Wings (翅).

​

Wings are not biological structures. They function as projection ports — the interface points at which a demon's will intersects with three-dimensional space. In their dormant state, Wings are invisible to the naked eye and pass through physical matter without interaction. Detection requires GIA-issue spectral sensors calibrated to specific dimensional frequencies.

​

Upon activation, Wings reshape dynamically — forming blades, hooks, or load-bearing structures capable of remote grasping, severing, and short-range levitation. Sustained activation draws heavily on the host's biological resources.

​

Note: Historical misidentification of activated Wings as divine or angelic phenomena is well-documented across multiple cultures.

Metamorphosis (蝶化): Full Dimensional Expansion

​

Metamorphosis (蝶化) refers to the state in which a Kindred allows their demon to fully expand its higher-dimensional influence — Wings manifesting completely, localized reality bending to accommodate a non-native ruleset.

​

This is a structural event, not a power surge. Within the affected radius, space, perception, and causality become subject to the demon's will. The demon transitions from passenger to temporary occupant.

Documented effects on the surrounding environment include spatial distortion, sensory override in nearby individuals, and localized suspension of standard physical law.

​

Resource consumption increases exponentially during Metamorphosis. Prolonged exposure causes irreversible damage to the host's physical and psychological integrity. Extended states risk permanent loss of host viability — the demon loses its anchor and retreats, leaving an effectively dead body.

GIA Operational Protocol 7-B: Metamorphosis is a restricted state. Unauthorized activation constitutes a Class II procedural violation.
