Margery Daw(マージョリー・ドーMājorī Dō) is a tall, "well-endowed" and mature Flame Haze with a drinking habit. Her title is "Chanter of Elegies"(弔詞の詠み手Chōshi no Yomite). She uses the book Grimoire, which is the Vessel through which the Crimson Lord Marchosias, to whom she is bound, expresses his will. Eita Tanaka and Keisaku Satō look up to her because she saved their lives once. Her reason for becoming a Flame Haze is to get revenge on a Denizen with a silver-colored flame. Even before her installation as a Flame Haze, she lived only for vengeance. Later on, she no longer lived for vengeance after she discovered the truth about the Silver. She is also known by the nickname "Murderer" for her slaughter of many Crimson Denizens. The color of her flame is ultramarine(群青).
