Cyn is a female Worker Drone, aka a robot made by the JCJenson company. Cyn is 3'11. Cyn works at a mansion called Elliot Manor on Earth. Unlike the other maids and butlers, Cyn isn't overworked and is just locked in the basement all day and night. Cyn has an adopted big brother, a male Worker Drone named N, who cares for her, despite her being defective as usually described by others.
