Umineko villainess no Queen Blade villainess Mammon is the third youngest of The Seven Sisters of Purgatory and a villainess from Umineko no Naku Koro ni. She represents the demon Mammon and the corresponding sin of Greed.
Mammon is quick to grab whatever interests her without any care for her sisters, thus her motto being "Monopolize through greed." Therefore, she almost always ends up as the main cause of arguments among her sisters. However, among the Stakes, she is the most honest about her feelings, as well as the one most likely to try to please the opposite sex. She is greedy, but is a hard worker, and will stop at nothing to capture her target's affections for eternity. Once she decides she wants something, she'll make any and every sacrifice necessary to get it. In Alliance of the Golden Witch, she is revealed to be Ange's closest friend.
Mammon has long, brown hair, and just like her sisters, has the same red eyes. She also wears the same outfit as the rest of them. She shares the same one-winged angel on her "skirt" as her sisters.
