Ghosts

Ghosts are a race of monsters in the Monster Girl Quest setting. They are one of the two undead races, the other being zombies.

Description
Ghosts are ethereal beings composed of dark magic and souls. This composition makes them resistant to physical attacks, but it also makes them vulnerable to magic.

There are various types of ghosts. Some, such as Page 17, possess books. These have the ability to draw a human man into an alternate universe within their book, in which they drain them for the rest of the man's life. Another type are mimics, which hide inside containers such as treasure chests. These exploit the greed of humans, preying on those who attempt to open them seeking treasure.

Ghosts can be summoned by mediums, to fight alongside them.
