02Appearance

Miu Miu has long, ratty blonde hair that's styled in several long tendrils with her eyebrows styled into circles. She wears heavy amounts of makeup and as a prisoner, she is dressed in a large sweater with pom-poms that resemble eyeballs. Miu Miu also wears stockings that have holes in them and a skirt with various words written across it, such as "Delicious" on the rear. She also wears boots with oversized leg warmers and a parting between the big toe and the other digits, likely a reference to the Maison Margiela Tabi boots.↗

Only the top half of her security uniform is shown. It is a long-sleeved collared shirt with two breast pockets and rectangular badges above them, as well as on the collars. Her left shoulder has a shield badge with text written above an emblem. Alongside it, she wears a belt with satchels and pockets attached to it.↗

03Personality

Miu Miu is the ruthless lead guard of the visiting rooms at Green Dolphin Street Prison.↗

Miu Miu seems to take her job as a guard rather seriously. Contrary to other guards, Miu Miu doesn't automatically use excessive force when dealing with the prisoners as she opted to openly confront Jolyne and show her Stand Jail House Lock as a warning first. This implies Miu Miu was willing to let Jolyne be if the latter didn't try to escape. Even after affecting Jolyne with the memory loss, Miu Miu keeps an eye on her. By looking at Jolyne's writings, she then discovered Emporio Alnino 's existence and enacted a plan that would make Jolyne lead Miu Miu to Emporio so that she could ensure Jolyne couldn't receive help.↗↗↗↗↗

While Miu Miu is generally less violent than the average guard, she remains a truly ruthless warden. As soon as she deems someone a prison breaker she doesn't hesitate to use lethal force. She was even willing to shoot Emporio, a small boy, to stop Jolyne. After Jolyne causes her more trouble than she expected, Miu Miu does confess that she's pleased at the prospect of Jolyne being shot down by the guards.↗↗↗

04Abilities

05Story

Background

Miu Miu is the lead guard in charge of the visiting room and front gate areas of the Green Dolphin Street Prison. Working alongside Whitesnake, Miu Miu has been preventing Stand users from escaping the prison thanks to her power. After Enrico Pucci fuses with The Green Baby, she is sent out to make sure Jolyne Cujoh does not meddle with Pucci's affairs anymore.↗

Jail House Lock!

Miuccia Miuller appears to Jolyne in her temporary confinement cell and relays a message from Whitesnake about how she shouldn't escape and should comply; if she does, he will make sure that Jotaro 's DISC will get out of the prison. Showing off her Jail House Lock as a warning, Miuccia explains that her orders are to kill Jolyne if she escapes and adds on that her other targets are Weather and Anasui. Jolyne declares that she is escaping and summons Stone Free to attack Miuccia.↗

Disguising herself as an inmate in the women's ward, Miuccia keeps an eye on Jolyne. She sits with Jolyne, interrupting her lunch and messing with her. Expressing her disgust when she steps on a cockroach, Miuccia proceeds to take her shoe off and put the cockroach in Jolyne's food then pours three sauces on Jolyne's plate to escape retribution.↗

Still following Jolyne, Miuccia eventually attracts her attacks but runs away, luring her in a forbidden corridor when guards threaten to shoot her. Jolyne escapes the guards and arrives in Emporio's ghost room, just as she planned. Entering the room, Miuccia takes a look at Emporio's Computer and realizes that she's identified her true identity. She declares Emporio a criminal and shoots several bullets at Jolyne and Emporio, hitting him and his computer screen.↗

Miuccia is then taken hostage by Jolyne and forced to instead use her ability on the guards, allowing Jolyne, Emporio and Ermes to easily escape Green Dolphin Street Prison.↗
