One of the many creatures in my upcoming game "Enter The Flesh Again".
These demons, or evil spirits, are incarnations of beings who committed a series of negative actions in previous lives. They are filled with anger, while they linger in confusion between different realms, lashing out with hatred at anyone who comes near them. These spirits will wander aimlessly in extreme suffering until they wear out their negative merits or until they are plunged out of their confusion by another, and get the chance to be reborn again.
