As the head of the Spina di Rosula, Navia is devoted to helping people of Fontaine, being likened as a "big sister" to everyone. She has a sharp mind and knack for investigating, being able to analyze things from different angles and find answers that other parties may miss. Due to her position, she is always accompanied by Melus and Silver, who she maintains a good relationship with, though following their deaths, expressed guilt at not being able to honor their wishes. She also enjoys baking.
