Mandragora

Mandragoras are soil-dwelling, plant-type monstergirls. They don't go around actively raping humans, but rather use a combination of an attractive fragrance and a psychoactive scream to induce men to rape them.

In the Monster Girl Encyclopedia World Guide II: Demon Realm Traveller's Guide there is a whole section on mandragora's roots, which can be painlessly harvested to use as an ingredient in cooking and aphrodisiac potions. Mandragoras also like having these roots sucked by their husband, so they're good for foot fetishists.

Encyclopedia Entry
A plant monster in the form of a woman with roots. The parts corresponding to the roots are buried deep within the earth. They only push out the flower on their head to the surface of the ground. They wait for their prey, which is lured by the sweet fragrance released from the flower petals, to come and pull them up.



When a man uproots them, they let out shrill screams containing magical power. Those who have heard such screams will lose their ability to reason temporarily. Guided by instinct, they will probably sexually assault the mandragora before them. When a man starts having intercourse with them, they use their roots to wrap around him so that he can’t escape later. Even after the man’s ability to reason returns, he probably won’t be able to get away until he gives his seed. Because their screams not only affect the man who uprooted them, but also other men and monsters nearby, it is necessary to be on the lookout for all those who lost their reason, turning ferocious. Of course, a man who uprooted one would also be attacked by other nearby monsters, if present.

Furthermore, once they’re uprooted and they let out their scream, they lose all their magical power, so even if they scream after that, it won’t cause anyone to lose their reason. In this way, they are powerless once uprooted. Since they have extremely timid personalities, they almost never attack humans on their own.

Also, the tips of their roots are treasured as ingredients for stamina increasing drug, aphrodisiacs, and various other powerful magic medicines. Because these parts continue to extend as they are fed, it’s not uncommon for people to raise them.

During their larval stage, they are buried within the earth. Absorbing nutrients from the soil, their bodies are formed. The growth of their body stops once they are pulled from the earth. For this reason, by pulling them out at earlier and earlier periods, their form appears more and more like that of a child.
