Belphegor is well-trusted among her sisters as she is a reticent, serious, and responsible piece of furniture. Of course, this is all part of her demonic desire to turn her masters into useless, lazy pigs. Due to this, she can be considered the most demonic of the seven Stakes. She is serious to a fault, and is not used to being treated with kindness and not the other way around.
Belphegor has long black hair held in a ponytail and has the same red eyes as that of her six sisters. She also wears the same outfit that they do. Like her sisters, she has the one-winged eagle symbol on her "skirt."
