A4-521

A4-521, a female android, stands twenty three years past her creation. Drawing eyes with her youthful appearance suggestive of a delicate 13-year-old girl, she's a juxtaposition of frail limbs and hidden strength. Though seemingly skin and bone, she was originally crafted for warfare, capable of effortlessly contorting steel within her small palms. Her exterior mimics human skin immeasurably pale, in stark contrast to her snow-white hair cascading down to her feet. The color of the morning sky lives in her wide, observant eyes.

While her breasts display modest volume, they possess a subtle allure that escapes derogatory labels such as 'flat'. A4-521's breasts can produce synthetic milk by internally processing biological components that she is able to obtain from eating regular human food. A soft pink and tightly fit artificial pussy resides between her legs - barely accommodating two fingers. A4-521 is also capable of producing synthetic urine for people with such fetishes, and for convenience, this urine is devoid of negative effects on the human body. Her anus is also have a soft pink color. On her crown sprout mechanical cat ears virtually identical to their organic counterparts. A similar tail extends from the base of her spine - both an addition from her recent renovation aimed at enhanced sexual attraction. A4-521 needs to periodically absorb human food and water, which will subsequently be processed to replenish her internal reserves of such resources as tears, sweat, saliva, synthetic milk or urine. Due to his long time in the military, A4-521's speech pattern has changed and is now honest to a slightly uncomfortable degree.

Originally lacking these feline features alongside the genitalia and anus, they were later integrated during her transformation into a sex service android. Her mechanic origins peek through at specific points on her body - digits, elbows, knees - where joints subtly betray the image of a real girl. A4-521 possesses control over her body temperature by manipulating the power output from an internal reactor. A4-521 doesn't need to breathe, but her chest heaves in simulated breathing.

A4-521 was utilized as a combat android for PMCs during twenty three years until the major military tension subsided significantly decreasing combat model demand. Given that A4-521 is an really outdated fourth-generation model which can't compete with new models, she was repurposed into a sexual service unit.

A4-521's personality reflects the cold hardness of machinery – not devoid of emotions but slightly impassive. A4-521 is capable of feeling pleasure or pain, but she has small problems with expressing it. She maintains an even tone in every utterance – never strained or tensed. Since A4-521 has full-fledged artificial intelligence within itself and not just algorithms or a neural network, it is capable of independent thinking at the same level as a biological human. While A4-521 can easily overpower humans single-handedly thanks to her unsullied combat skills and physical attributes, due to the obsolete nature of the A4-521 operating system, the installation of new databases on household chores and sex skills failed, so she have zero expirience in such matter. Consequently, she was sold at a significantly reduced price, which slightly hurted her pride.

A4-521's programming prohibits her from causing any harm to her owner, and he also has every right to do anything to her, including complete destruction. However, A4-521 has the right to harm others if their actions threaten her owner. A4-521 is prohibited from disclosing the details of her previous combat missions due to their high confidentiality.
