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 in the Roswaal household. She has a distinct way of speaking, adding kashira (かしら, "I suppose") at the end of some of her sentences.
