She is an artificial spirit created by the Witch of Greed for unknown reasons. 400 years ago, she was told to wait in the library for "That Person" who would grant her salvation. Beatrice generally looks down on others and is bad at dealing with people who try to get close to her. Despite being full of bravado, she's a lonely person, and is softhearted beyond her perceived stubbornness. She is affectionate towards Puck because of their similarities and favors him over the others.
