Demi-Spiritual Lifeform

Demi-Spiritual Lifeforms (半精神生命体) are a type of lifeform that can be called an inferior version of a Spiritual Lifeform.

Properties
Demi-Spiritual Lifeforms are beings that exist in a framework beyond that of any material lifeform and aren't bound to a Material Body if they even possess one. They can broadly be split into two categories, those who have become Enlightened among Demi-Physical Lifeforms and those that are naturally born with this status typically within Spiritual Worlds.

Being unbound to flesh and not requiring a material body to function naturally means that Demi-Spiritual Lifeforms have their memory storage and thoughts located within their Spiritual Body or even deeper within. And for those that possess a Material Body, it becomes almost unbound by lifespan, having it's physical structure reconstructed over time to surpass the limits of organic life. Even if their brains are destroyed, they can regenerate it without any issues.

Though Demi-Spiritual Lifeforms are extremely close to Spiritual Lifeforms in nature they remain inferior in one key aspect, their mortality. If the spiritual body of a Demi-Spiritual Lifeform is destroyed, then they die for good, having been unable to escape the constraints of their body and cheat death.
