Jail House Lock (ジェイル・ハウス・ロック Jeiru Hausu Rokku?) is the Stand of Miu Miu featured in Stone Ocean.


Jail House Lock is a humanoid Stand with a brain-like head, an emaciated body and conical arms. Its body is patterned as though with stitches, including patterns on the chest resembling those of denim pockets.


Cycling Short-term Memory Loss: Jail House Lock has the ability to cause a person of Miu Miu's choice to be able to retain a limit of 3 items in their short-term memory. If the target of Jail House Lock learns a fourth "thing", they will forget the first thing they learned. The target may continually learn new things at the cost of forgetting the first item. However, long-term memories attained before Jail House Lock's influence remain.



  • Jail House Lock's appearance could reference techniques of discipline or torture related to prison such as solitary confinement, starvation and mutilation. In theme with Araki's choice of designer names for many characters in Stone Ocean, it could also refer to anorexia nervosa, as is occasionally accredited to fashion marketing.
  • The pattern on Jail House Lock's body in its resemblance to denim stitching may reference historical U.S. prison uniforms, as featured in its motion picture namesake.
