Body

Body (体) or Corpus refers to 3 out of 4 fundamental existential components of most lifeforms. The Soul, the remaining component, is surrounded by the three bodies, from innermost to outermost: Astral Body, Spiritual Body, and Material Body.

Astral Body
Astral Body (星幽体) is the innermost Body which surrounds the Soul. It is basically the "Vessel" of the Soul.

Spiritual Body
Spiritual Body (精神体) is the body-type responsible for the memories of an individual that prevents those with just Soul and Astral Body from collapsing. It serves as a virtual memory.

Material Body
Material Body (物質体) refers to the physical body as most know it. It is required for Daemons and other Spiritual Lifeforms to permanently remain in the material world without being affected by the rejection force of the world.
