Millicent "Millie" Fitzsimmons is the main protagonist of Count the Ways, the third story from Fazbear Frights 1: Into the Pit.
Millie is a stereotypical "goth" teenager. She obsesses over death to the point where she constantly reads and writes poems about it. She even romanticizes death as an anthropomorphized, attractive man - specifically Curt Carrion, her favorite singer.
