A ghoul is a living being whom looks exactly like a human, though there are very
big differences between humans and ghouls. First of all, ghouls cannot eat the food humans eat, ghouls can only eat humans, and they can only drink coffee and
water. Ghouls also have a muscle like object (called a kagune) that comes out of a position in their back, Depending on what kind of ghoul they are. It can either be an okaku (shoulders), kokaku (shoulderblades), rinkaku (waist), or binkaku (tailbone). Each type of kagune have their pros and cons. If a ghoul commits cannibalism, then they get a strong,
hard to
control kagune kalled a kakuja. Ghouls only have to eat one human once a month to keep their strength up and to keep their kagune 'fed'. When ghouls are
hungry, the white part of their eye turnes black and their cornia turns red. If ghouls cannot control when their eyes change, it is something that points them out from the rest of
society.
