The caretaker of the Roswaal Mansion's Forbidden Library.
Her milky white hair is tied up in twin drills.
She seems to always be in a bad mood.
She looks like a fairy when she walks, her fancy dress trailing behind her.
Beatrice (AWK)
She calls herself Betty and is the librarian at the Forbidden Library.
She lives on her own in a room as the Roswaal Mansion that was hidden with Door Crossing.
She is arrogant and does not get along well with others.
While she often finds herself at odds with Subaru Natsuki, who happened to break her Door Crossing, they actually get along fairly well.
