Peri mostly acts like a spoiled child, crying very easily when upset and will lash out violently. Such feelings stems from the murder of her mother by a servant when Peri was young. Peri's father's general apathy toward her violently injuring servants further stunted her sense of morality, escalating to her outright murdering anyone she feels has wronged her. To further her childish behavior, in the Japanese version, Peri often refers to herself in the third-person, a trait usually expressed by young Japanese children or adults portrayed as childish.
