Ghost

Background
Ghost disliked the acts of sex and love and hated the body and its functions, and especially hated having sexual urges when he was alive; so he commited suicide, hoping it would grant him a reprieve from lust.

Unfortunately, he quickly learned that ghosts get horny too.

Angry that his plan had failed, he instead decided to make everyone else sick of sex.

Personality
Probably has more spite than Crange does
