アルラウネ

A famous plant type monster. There are many different kinds of Alraunes, and their personality and appearance vary wildly depending on the type. This Alraune is of a very pure type, and has an upper body very much similar to a human’s. They can live off photosynthesis alone, but they prefer male semen. Their bodies all contain an intake for semen, and will carefully extract it from any captured male. Since it’s designed to feed, the hole is quite capable of forcing any man to come quickly. Alraunes generally have a gentle personality and will not suck a man dry. Always optimistic, they live a mostly carefree life. [From In-game Monsterpedia]
