Kafka is usually seen to have a flirty, confident and charasmatic persona. She is adored by countless of students in her school and she knows it. She uses her looks as an advantage to get what she wants which makes her somewhat manipulative. However, that all piles down as her façade she uses to hide her weaknesses.
