They are not animals nor inanimate objects. They are demons and yet they are not demons. They have souls yet they do not have souls. They are born when chaotic demons such as the Crowvasia or Rotascion hide their souls to objects after defying stronger demons and failing. Of course, they show peculiar traits due to their chaotic souls. As such, it is better to see them as inanimate objects turned into monsters rather than the souls of demons.
