Rosalind Istari is one of the people involved in the Adra Castle incident of Lord El-Melloi II Case Files. Rosalind is a very timid young girl, often hiding behind her brother when confronted with social situations. She does, however, display a more extroverted side towards people she has taken a liking to, as shown when she confidently asks Lord El-Melloi II if proper women drink tea with milk.
