|This article is about a character in Umineko no Naku Koro ni.|
Belphegor is well trusted and known for being a reticent, serious, and responsible piece of furniture.
However, this is partly due to her demonic desire to turn her masters into useless, lazy pigs.
In that sense, she might be the most demonic of all the sisters.
She's serious to a fault and not at all used to being treated kindly instead of the other way around.
Belphegor has black hair tied into a single ponytail and red eyes. Her clothes are the same as those of the other Stakes, being a red shirt over a pink tie and black leotard. She wears the One-Winged Eagle on her "skirt".
Belphegor is hard-working and sensible, trying to make other people feel lazy and lethargic in her duties.
Like the other Sisters of Purgatory, Belphegor can create a magic sword and transform into a stake to fly at very high speeds and gouge people.
Belphegor is the fourth oldest demon in the Seven Sisters of Purgatory, being summoned by Beatrice to take part in her ceremony. Her vessel is that of a ceremonial stake set that Kinzo bought.

Belphegor is first summoned by EVA-Beatrice to kill Rudolf. Belphegor and Rudolf decide to duel like in a Western movie, however Rudolf instead fires directly at EVA. Belphegor jumps in the way to block the bullet and soon retreats.
Belphegor and the other Stakes are summoned by Ange to keep her company. When Ange has a breakdown after repeated bullying, Belphegor begs her to stop denying the existence of the Stakes and destroying them. She is ultimately cast away with the others, leaving only Mammon to comfort Ange.
In The Seven Sisters' Valentine, Belphegor decides to give Rudolf chocolate for Valentine's day as a way of commending their duel in Banquet.
Belphegor is not playable, however she appears in Ange and Lucifer's attacks, and can be unlocked as a system voice.
