A half-mazoku is a composite being created when a mazoku abandons its natural existence as spirtual being in order to merge with another being, or when a creature is partially transformed into a mazoku by other magical means. In certain cases, it can be seen as some kind of possession. If the half-mazoku is the product of a merge between a human and a mazoku, the souls of both coexist within the merged being. One or the other may take complete control at times. If the two souls have conflicting desires, then the half-mazoku may hesitate or become paralyzed.
