Life Spirits

are beings with no shape or individuality that are described as "pieces of their Great One" and the font of energy that raises all races in many worlds, including Humans, Demons, Goddesses, Giants, and Fairies.

Overview
According to Zarura N'Du, a Life Spirit themself and an energy golem created by Percival's Magic called Hope, says that all Life Spirits are "Pieces of their Great One" who, as of the present, is still a complete mystery.

A particular Life Spirit happened to inhabit the body of the human baby Percival, by some machination orchestrated by his father, Ironside. The love he received from Varghese over the following years led him to develop the feelings and individuality that a Life Spirit should never have, which in turn led him to forget everything related to the Life Spirits.

Appearance
Life Spirits do not possess any shape or form, being seen as blobs of energy similar in appearance to the Magic called Hope that Percival wields.

Physiology
Life Spirts are described as all being parts of a greater, unnamed being and are implied to have no gender and being completly neutral due to naturally not possessing any kind of emotion (with the exception of Percival). They also lack any individuality or physical forms, being seen as pure energy and in most cases a simple-looking blob, but when in need of a physical body, they can possess other creatures to use as vessels like Goddesses or Demons do, or even Chaos itself.

Powers and Abilities
Not much is known about the Life Spirits' abilities but they're shown to be capable of sharing a single mind with each other, and also being capable of inhabiting other creatures' bodies as shown with Percival and the Behemoth.

Zarura N'Du states that Life Spirits can use the hope of others to spread life, the same way they use despair to spread death.

Trivia

 * The Life Spirits' energy-like appearance makes them appear similar to Percival's Magical Power, Hope, implying a connection between them given that Percival himself is a Life Spirit. Indeed, Zarura N'Du, who refers to himself as a Life Spirit like Percival and Behemoth, has been brought forth by Hope.
 * Chion describes the Life Spirits as the loftiest of all Spiritual Beings.
