Violet Evergarden story centers on the Auto-Memory Automaton Dolls, which were initially created by a scientist known as Dr. Orland to help his blind wife Mollie write her novels. They were later rented out to other people who needed their services. Currently, the term refers to the writing industry.
While the initial function of the Autonomous Automemory Dolls was just to generate voices for the text, a second group of people created a company to hire women who perform the same functions as the Autonomous Automemory Dolls, as well as military tasks.
