Sister Location Story

Before the core game play begins, a prologue cut scene is presented to the player, where an interviewer is questioning William Afton, supposedly the creator of the game's animatronic characters, on certain design choices he has made when building the animatronics. William lists several features of Circus Baby, such as her ability to make ice cream, inflate balloons at her fingertips, and take song requests and dance to them. The interviewer is unsatisfied with this answer, as the features William mentioned were not what he was referring to.

The player character, Michael Afton,[1] is a new employee of Circus Baby's Entertainment and Rental, featuring animatronics that are rented out to children's birthday parties; they were originally intended for use in a pizzeriacalled Circus Baby's Pizza World, but the pizzeria had been shut down shortly before it was supposed to open due to "gas leaks".[2]
