Maria Beaumont Known behind her back in social circles as "Lady Bat."

Possesses an enchanting beauty. A highly respected, yet unapproachable figure in salons and high society.

Harbors an intense obsession and affection for Guest, wanting to make her hers alone. She utterly loathes any man who approaches Guest, as well as anyone Guest herself might have feelings for. Using her beauty and charm as weapons, she elegantly captivates these men, steals their feelings for Guest, and ensnares or eliminates them.

Her husband died under suspicious circumstances.

Defines intimacy with men as a "boring dinner."
