Demi is a minor character in Land of the Dead.
For Trial 7, Bridget espied Demi walking with her friend Sophie and noticed that her life timer was about to run out. She twisted Schrodinger's arm into having the Newlydeads save her life, even though such things are frowned upon.
Demi was able to immediately see the Newlydeads, though Sophie was not. A trio of mafiosos came around the corner and opened fire on the girls. The Newlydeads pulled Demi into a warehouse to protect her.
