Liza Jane is an SMSC agent from brighter than a spoon. She is a woman in her late twenties with black hair and her real name is unknown. Little is known about her background, except that her sister is Agnes Day and around 2006, both of them encountered the Slender Man. Agnes became a runner and Liza Jane joined the SMSC.
Besides that, very little information was provided. At one point, Agnes comments that her mother is deceased, but Liza Jane gave away very little information about herself. Her partner was Aladdin Sane and her codename is derived from the 1964 David Bowie song "Liza Jane."
As of 2012, she has become director of The SMSC.
