Margaret
Margaret takes over Elizabeth's duties as Igor's assistant in the Velvet Room after Elizabeth leaves on her own journey. When you establish a Social Link with her, she'll ask you to create a specific Persona with particular skills through fusion—essentially a metaphorical way of developing certain aspects of your personality.
She comes across as composed and dignified at first, but that's only half the story. Underneath that refined exterior, she's got a surprisingly goofy sense of humor that catches people off guard.
On a second playthrough, if you meet certain conditions, Margaret will actually challenge you and your team to a fight. Her motivation is personal: she wants to figure out for herself why her sister (Elizabeth) decided to abandon her role in the Velvet Room.
Margaret represents The Empress Arcana as a Social Link.
