HMX-17c Silfa

A robot, she is model HMX-17c, making her a "sister" of sorts to "Ilfa" and "Milfa". She was previously only mentioned in the game. She was shipped to Takaaki's home to serve as his personal maid. Her housekeeping performance however leaves a lot to be desired, plus she's quite emotional for a robot, to the point that she needs to be "disciplined" by HMX-17a Ilfa. She is however extremely shy, if not downright scared, when trying to interact with other people in the society, to the point of being called a "hikki(komori)" by Harumi and has a tendency to cover herself with and stay underneath a cardboard box all the time.
