For any species to survive and continue, "reproduction" is inevitably essential. There are countless reproduction methods in the Multiverse, such as sexual reproduction, parthenogenesis, plane realm breeding, heterogeneous assimilation, and so forth, each more bizarre than the next.
Ghoul women, these ugly and wicked creatures, also have their unique way of reproduction.
Some say that the birth of ghoul women is based on a horrifying curse, just like werewolves, vampires, sirens, and harpies. This viewpoint is not entirely groundless, as understanding their reproduction method may lead to the same idea.
When an adult ghoul woman wants to give birth to offspring, she does not seek out males of her race for some pleasurable activities to satisfy her needs, because ghoul women do not have males. Likewise, she does not seek the seed of life from males of other species.
What this ghoul woman wants to do to give birth to her offspring is to devour a human baby.
