Jolyne is the protagonist of JoJo's Bizarre Adventure Part 6, and notably the first and only female "JoJo" in the series. She's the daughter of Jotaro Kujo.
On the surface, Jolyne comes across as a troublemaker—hot-headed, mouthy with authority figures, and reckless in chasing whatever thrill comes her way. She resented her father for his long absences and blamed him for steering her toward a life of poor choices. But beneath that attitude lies genuine integrity. She cares deeply for her mother and will go to bat for her friends without hesitation, driven by her belief that the people she loves are fundamentally good at heart.
That faith in others is both her strength and her weakness. She's trusting to the point of naivety, which is exactly how she ended up caught in Romeo's deception and landed a 15-year prison sentence. Still, despite her rough edges and the mess she's gotten herself into, there's something solid underneath—a moral core she can't quite shake, no matter how hard she tries to play the part of a lost cause.
