Jolyne is a wayward girl from Florida in her 20s. She has a dual nature: she can be very polite, sweet, and caring, but can also become straightforward and menacing when provoked. She acts like a pretty average young woman and is polite to strangers. She harbors a deep resentment for her father, Jotaro, due to his absence, but loves her mother with all her heart. She strongly dislikes being called 'Jojo'.
