シャドー娘

A Monster of unknown lineage who appeared in the Haunted Mansion. She appears to have been birthed from the residual magic leftover from nearby studies of magic such as necromancy. Her body itself is comprised of countless souls of other beings. She continues to grow her body by taking in the souls of other beings into herself. A monster created while Chrome was experimenting with zombies, she was a hidden danger growing in the mansion. Of course, above all, male semen is still her primary source of power, and she will seek out human men to acquire it. She will give genital stimulation to encourage ejaculations in order to extract his semen. But in the end, she will incorporate their body and soul in her own. [From In-game Monsterpedia]
