is the Sakisaka family's household android, who has the appearance of a young woman. At home, Sammy's behavior is passive and emotionless. At the Time of Eve, she refers to Rikuo, Naoko, and their parents as her family. She wishes to make the members of her family happy, but is aware that demonstrating independence, even for their benefit unsettles Rikuo who is the only one aware. Sammy therefore lies about doing anything out of the ordinary when Rikuo questions her activities. While Sammy appears emotionless as an android, she is very insecure and afraid of hurting others, especially Rikuo. She would therefore do things covertly such as taking detours during her regular schedules or attempting the piano late at night when no one is awake.
