I guess it would depend on the situation. If the aliens were abducting humans and mamono, or if they start to eradicate the life forms on the planet, I would believe that the demon lord would declare war on the aliens. If they just stop by for a visit, then she would probably be indifferent, since the mamono are bred to breed with human males, not extraterrestrial ones.
