In this case, a different VA may voice the two sisters.

Caroline dislikes the Phantom Thieves of Hearts and openly hopes for their eventual arrest. She tends to speak to Justine in a demeaning manner. Additionally, she doesn't seem to hold the protagonist in very high regard, as she refers to him as "inmate," and kicks him into the Velvet Room whenever he goes to enter. She is generally ill-tempered and impatient, even after the twins' Confidant levels up and she grows to respect the protagonist as a friend. There are certain inconsistencies between how she seems and her real personality, and as according to Justine, she was mortified when she first witnessed persona fusion and practiced intimidating poses to use on the protagonist but is too embarrassed to. She could be considered a tsundere, but this is relatively ambiguous.
