Jolene Joestar is the main protagonist of Part 9 and is the alternative universe counterpart of Joylene Cujoh, she was framed for major fraud but bailed out by Josuke Higashikata. While in prison, Jolene developed a strong desire to bring justice to those who wrongfully imprisoned her, and joins Josuke on a journey to discover more about this shadow organization and attempt to end their corruption.

History
Jolene Joestar was born on May 30th, 2002. Her parents were irresponsible teenagers when she was born, leaving her with her paternal uncle, Arthur Joestar. Arthur raised her as a daughter alongside his son (Jolene's cousin) Jibby, and although their family was not wealthy Jolene was able to live a safe, happy childhood.

Jolene took an early interest in building computer hardware, something Jibby liked to do. He would fix computer equipment to help his father pay the bills, and Jolene joined in helping as she learned more and more from hanging around Jibby. At one point, Jibby left, not telling Jolene why. Jolene was devastated, but continued to work hard in school and get excellent grades. Jolene had a goal of making it into one of the best schools in America to study computer engineering, and she was thrilled to be accepted into all the schools she applied to. She still missed Jibby terribly throughout all this, however, and constantly wondered where he'd gone to.

Jolene would sometimes assemble computers for her friends at a small charge, and this put her in touch with a local gamer, Thoko. The two became friends quickly, having a mutual appreciation for retro consoles. When Jolene heard that Thoko lost his DS in a bet at a young age, she decided to give him one that she had received second-hand a while back.

On her 18th Birthday, just about a month before graduating from high school, Jolene was relaxing at her computer in the afternoon when all of a sudden her monitor started to fill up with confidential information about bank accounts for massive corporations. Jolene was confused, but attempted to stop what was happening. While working on undoing whatever was going on, two FBI agents walked into Jolene's room and arrested her.

Jolene was given a lengthy sentence in a maximum security prison. She did a full year without the use of her stand, until some inmates abused her to the point where her life was in serious danger. Her stand, Silver Lining, then awoke.

Jolene did another year in prison, now with Silver Lining. She was able to fend off the inmates who were abusing her, but she was still miserable. She found her stand could have broken her out, but she would be easy to track upon breaking out and she would have no way of getting around quickly, so she decided breaking out would do her no good. Shortly after doing two years, she was bailed out by Josuke Higashikata

Stand
Silver Lining:

Silver Lining allows Jolene to turn into a Mercury-like metal.

Jolene can decide, in this mercury state, whether to change her entire body or a portion of her body into a solid metal or a liquid metal. Both forms have their upsides and downsides. A solid state would allows Jolene to tank several attacks, preserving Jolene's form while decreasing her mobility, as movement would be a lot more stiff and difficult. However, a metallic punch has a lot more destructive force, so it is both powerful on offense and defense.
