Miuccia Miuller, nicknamed Miu Miu, is a minor foe in Stone Ocean. As chief of the guards at Green Dolphin Street Prison, she answers to Enrico Pucci and moves against Jolyne Cujoh's attempt to break out. Her Stand, Jail House Lock, tampers with the memories of anyone who crosses her.
Gwess reads a privileged, high-society air off Miu Miu the moment they meet. Blonde and stringy, her hair falls in several drooping coils, and her brows are drawn as tidy circles above heavily painted features. Posing as an inmate, she favors an oversized sweater trimmed with round pom-poms shaped like eyeballs. Torn stockings and a skirt scrawled with odd captions, one of them reading Delicious across the seat, round out the look.
Miu Miu commands a humanoid Stand called Jail House Lock. Its power caps how much fresh information a victim can hold, keeping them to just three new memories at any given moment. The instant a fourth detail arrives, the earliest one is erased to make room, so targets can never build on what they learn. She exploits this by sending guards in bunches larger than three, leaving her enemies unable to track them all.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
Though she first passes for another prisoner, Miu Miu actually oversees security at the visiting room and main gate, planted there to stop Jolyne Cujoh from interfering any further in Enrico Pucci's plans. Her ability snares not only Jolyne but Emporio Alnino, who keeps forgetting what he is doing and gets zapped by an electrical outlet while trying to warn her about the disguised captain.
Once Jolyne finally holds the thread long enough to reach Emporio, she pins the guard as her true opponent. Miu Miu answers by flooding the corridors with guards in units of four or more and nearly seizes the advantage. Jolyne breaks through with a flurry of blows, grabs her as a shield, and slips out of the prison with Emporio and Ermes Costello alongside her.
Yes, Miu Miu, whose full name is Miuccia Miuller, is the chief guard at Green Dolphin Street Prison in Stone Ocean. She poses as an inmate while actually overseeing security at the visiting room and main gate for Enrico Pucci.
Miu Miu, or Miuccia Miuller, is voiced by Yuko Kaida in Japanese and Morgan Garrett in the English dub of JoJo's Bizarre Adventure: Stone Ocean.
Miuccia Miuller's Stand, Jail House Lock, caps how much fresh information a victim can hold to just three new memories at a time. The moment a fourth detail arrives, the earliest one is erased, so targets can never keep track of everything happening around them.
Miuccia Miuller uses Jail House Lock to make Jolyne Cujoh and Emporio Alnino keep forgetting details, then sends guards in groups larger than three so her enemies cannot track them all, nearly overwhelming Jolyne in the prison corridors.
Miuccia Miuller is defeated when Jolyne Cujoh finally pins her down as the true opponent after holding a thread of memory long enough to reach Emporio Alnino. Jolyne breaks through the guards with a flurry of blows, grabs Miuccia as a shield, and escapes the prison with Emporio and Ermes Costello.
