Miuccia Miuller

Miuccia Miuller (ジョナサン・ジョースター) (a.k.a. Miu Miu) is an antagonist from Part VI: Stone Ocean and the head guard of Green Dolphin Street Prison.

Appearance
Miu Miu is described by Guess as a blonde giving off an air from having come from an upper-class socialite family.

Synopsis
Introduced in a way that she appears to be an inmate, Miu Miu is actually the head guard in charge of the visiting room and front gate areas of the Green Dolphin Street Prison sent out to make sure Jolyne Cujoh does not meddle with Enrico Pucci's affairs anymore.

Her stand causes trouble not only for Jolyne, but also for Emporio Alnino, who attempts to contact Jolyne about her true identity as the head guard and is shocked by an outlet several times due to his forgetfulness induced by her stand's effect.

When Jolyne finally remembers to find Emporio, she manages to make Miu Miu out to be her enemy. Unfortunately, Miu Miu sends the guards after her, taking care to send them in squads of more than three to make it more difficult for them to counter her attacks. Right as she is about to get the upper-hand, however, Jolyne defeats her with a series of punches, uses her as a hostage and as a means for them to escape the prison, and escapes with Emporio and Hermes Costello.

Trivia

 * The way she encounters Jolyne for the first time is very similar to how Chaka encountered Polnareff, with thier stand activated before catching them off guard with thier abilities.
