Miu Miu
Miu Miu is the Green Dolphin Street Prison head warden — a Stand-user prison official tasked with monitoring inmate movement and enforcing institutional security. Her Stand Jail House Lock produces memory restriction that limits all opponents within range to remembering only three pieces of information at a time — anything beyond the three slots is forgotten. She is one of Pucci's covert allies inside the prison and dies in the Cape Canaveral final-arc.
Story
Stone Ocean
Part 6 · 2011Miu Miu's pre-Stone-Ocean biography is depicted across one chapter as a career corrections officer whose institutional rise was the result of her Stand-mediated surveillance capabilities. Her Stand Jail House Lock awakened in her early thirties via Stand-Arrow contact through Pucci's prison-circulation programme, and she immediately commercialised the mechanic for institutional-security applications.
Her role across Stone Ocean's middle act is Pucci's covert ally inside the prison — Miu Miu provides administrative cover for Pucci's Stand-research operations and uses Jail House Lock to disrupt Jolyne's investigation activities. Her combat scene against Jolyne's crew exploits the memory-restriction mechanic across multiple chapters, with the crew unable to retain the tactical information needed to defeat her until Jolyne identifies the three-slot constraint and engineers a memory-overflow workaround. Miu Miu dies during the Cape Canaveral final-arc.
Powers & Abilities
Jail House Lock
StandJail House Lock is a Long-Range Stand that produces memory restriction across any opponent within range. All targets within the Stand's effect-radius are limited to remembering only three pieces of information at any time — any fourth piece of information learned automatically erases one of the previous three from memory. The mechanic is the franchise's first depicted memory-cap Stand combat ability.
Combat applications scale from straightforward (force opponents to forget the tactical plan they were about to execute) to creative (force opponents to forget which Stand-user is the actual threat) to strategic (engineer compound situations that exceed the three-slot memory capacity, leaving opponents permanently confused about their own combat position). The Stand's primary structural constraint is opponent-awareness: once an opponent identifies the three-slot constraint, they can engineer memory-overflow workarounds — exactly what Jolyne eventually does.

Trivia
- Miu Miu is the Green Dolphin Street Prison head warden — one of Pucci's covert allies inside the institution and a structural argument that Pucci's Heaven Plan operates with institutional-security cover that conventional inmate-investigation cannot bypass. Her commercial-brand-named codename fits Stone Ocean's pattern of using fashion-industry brand names for the prison's female Stand-user characters.
- Her Stand Jail House Lock is named after the **Elvis Presley 1957 song *Jailhouse Rock***. The Stand-naming continues Stone Ocean's rock-music Stand-cluster — Jail House Lock's deliberately-doubled-name register parallels the Stand's three-slot memory mechanic in producing a structurally-restrictive combat profile.
- Jail House Lock's three-slot memory-cap mechanic is the franchise's first depicted memory-capacity Stand combat ability. The mechanic family — Stand User restricts opponent cognitive capacity rather than producing direct damage — has been read by long-form JoJo critics as the structural precursor to several later franchise cognitive-Stand designs across JoJolion.
- Miu Miu's death during the Cape Canaveral final-arc is one of Stone Ocean's most-restrained villain-death sequences. The manga depicts the death without extended combat — Made in Heaven's time-acceleration eliminates Miu Miu among many other Stand users in the universe-reset's preparatory minutes.

The death is one of Stone Ocean's most-restrained villain-death sequences, depicted without extended combat in the broader Cape Canaveral casualty cascade.
How do you defeat Jail House Lock?
Jail House Lock's three-slot memory-cap can be bypassed by opponent-awareness workarounds. Once an opponent identifies the three-slot constraint, they can engineer memory-overflow situations that exceed the cap's capacity — exactly what Jolyne Cujoh eventually does during Stone Ocean's middle-act confrontation. The Stand's primary structural constraint is that it cannot prevent the opponent from learning about its three-slot mechanic.
