Beelzebub (ベルゼブブ Beruzebubu?) is advanced-level furniture created by Beatrice. Beelzebub is the gourmet of the sisters and is known for being a big and picky eater. Her personality is similar to Mammon's, and the two sisters often fight over the same thing. She's always talking about food, which makes her a calming influence among the sisters. However she also has that disturbing desire to kidnap pretty boys and store them in the food cellar...
Requiem of the Golden Witch
Beelzebub appears as the servant Belne during Clair Vaux Bernardus's theater performance. Belne is instrumental in spreading the myth of the witch Beatrice; after being repeatedly pranked by Yasuda, Belne came to believe that the witch was real and spread this belief to other servants.
Twilight of the Golden Witch
During the Halloween after-party, Beelzebub flirts with Toshiro Gohda.
After the Goats begin to swarm Rokkenjima, Beelzebub helps protect the lower floor of the mansion. Like her sisters, she is rendered incapable of attacking the Goats after they deny her, referring to her as a "paperweight."
