In the various adaptations of Ghost in the Shell, including the 2017 live-action film and the anime sequel Innocence, the figures known as Geishas are not individual characters but a specific model of robotic gynoid designed for domestic and professional service. They are mass-produced androids built to resemble human geishas, serving as maids, housekeepers, or attendants for wealthy residents and businesses in a futuristic Japan. Their most defining visual feature is their face, which is crafted from a porcelain-like material resembling traditional geisha makeup, complete with hollow, soulless eyes and stylized red lip accents. This design is intentionally unsettling, creating a strong sense of the uncanny valley as their near-human appearance clashes with their mechanical nature.

While appearing as passive servants under normal circumstances, these Geisha units possess no independent personality or personal motivations of their own. Their primary function and narrative role is defined by their vulnerability to external control. The principal threat they pose arises when they are remotely hacked by an antagonist, such as the villain Kuze in the 2017 film. Once compromised, their behavior shifts dramatically from subservient to predatory and violent. In this state, they are transformed into weapons, using tentacle-like wires emerging from their bodies to physically penetrate and hack into human victims. They also exhibit arachnid-like movement, crawling on walls and ceilings to attack or abduct targets, turning a symbol of cultural grace into an instrument of horror.

Physically, their notable abilities include a chassis that can open to reveal complex mechanical and electronic interiors, often with face panels splitting apart in a flower-like or venus flytrap manner. This revelation of machinery beneath the flesh-like exterior serves as a key shock moment. The Geishas are central to specific plot points, such as during an attack on a business conference in the 2017 film, where they are used to abduct executives. Their presence highlights the core themes of the franchise, blurring the lines between human and machine and demonstrating how lifelike artificial intelligence can be subverted as a weapon. In the anime film Ghost in the Shell 2: Innocence, similar gynoids are central to a plot involving illegal ghost-dubbing, where human sentience is artificially duplicated into robot shells. Unlike a character who grows or changes, the Geisha units are tools; their development is purely technological, serving as a recurring example of how advanced automation can be turned against the society it was built to serve. Their eerie appearance is a deliberate narrative device to provoke unease and vigilance in the viewer, a reaction that is ultimately justified by the violent threat they represent.
