Any type of mamono can be originally a human woman, any type can also create a demon realm by having enough sex (though it's usually a community effort) enslavement contracts are just a type of spell, so theoretically any spell caster could make one, Demons and Dark Mages just seem particularly fond of doing it.

Majin types are justba type of demon that looks very similar to a normal human.
