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 "I suppose" (かしら, kashira) and "in fact" (のよ, no yo) at the end of most of her sentences.
