What do you mean by original incubi? The real world mythic incubi were simply alternate forms of succubi. In the MGE they have always been men who have been changed to become the ideal mate for a given monster girl (and for the chaos girls the ideal mate includes the ability to change form). KC has admittedly edged away from saying they are still truly human (and even when he did he said they counted as human only because they still produced human mana), more that they are altered/evolved humans.

But the setting has also long made it clear that what a being is considered to be is not entirely dependant on how they look physically, i.e. the multiple monster races that are physically largely identical to humans and count as monsters only due to the nature of their mana (and sexual skills).
