Nadia is very courteous and considerate with a playful streak. As a Countess, she's also authoritarian and prefers honesty to soothing lies. She's giving, willing to give gifts to her friends and acquaintances, saying they "need only ask".

Her overarching goal beyond capturing the murderer of her late husband Lucio is to make Vesuvia a better place for everyone - to fix the city and prove to Vesuvia and its people that her house hasn't completely failed and abandoned the city. She's angry at and disappointed in the Courtiers for failing to properly help the city in her absence, especially for allowing Vesuvia's poor people on the streets to go hungry and for not helping to rebuild the flooded Shopping District. She firmly believes that the city should provide for its people.

She tends to react sensitive to topics surrounding her sisters.

Nadia experiences numerous headaches throughout the game, and admits to the Apprentice that she remembers very little of her life with Lucio. She is not fond of people who appear to be "fake" fortune tellers; however, she greatly respects those who are legitimate magicians. She's also very intelligent with machinery, creating various mechanical toys for Chandra as well as the intricate library door and the clock in the Great Hall that keeps track of moon phases.
