The young bride is the younger of two daughters belonging to a local noblewoman. Initially repelled by Blue Beard's unnatural facial hair and the mystery surrounding his missing former wives, she changes her mind after attending an eight-day luxurious country party. She possesses a strong sense of curiosity that drives her to investigate restricted areas of her new home when her husband leaves on business.

Blue Beard is a wealthy landowner whose prominent, unnatural facial hair frightens the local women. He uses his vast riches, lavish country estates, and extravagant parties to court potential wives. He demands strict obedience regarding his private spaces, giving his new bride access to all his wealth except for one small room on the lower level.

Sister Anne is the older sister of the young bride. She attends the initial eight-day celebration at Blue Beard's country estate and remains a steady presence in the household after the wedding. She acts as a vital confidante for her younger sister.

The brothers are two young military men, one serving as a dragoon and the other as a musketeer. They are scheduled to visit their sister at her new country estate. They represent a protective family presence for the young bride.

The mother is a local lady of high social standing who introduces her two daughters to Blue Beard. She participates in the eight-day celebration at the country house that ultimately convinces her younger daughter to accept the marriage proposal.
