The eldest daughter of the Sagara family. She is a day-care center worker in Tokyo. She is good-looking, talented, and has a very gentle personality.

The third daughter of the Sagara family. She is a first-year student at a school in Tokyo. She is frighteningly quiet and reserved, and even when she is standing next to you, you may not be able to tell she is there. Although her presence makes her difficult to notice, she is in fact quite a beautiful girl. She has always had a tendency to be shy, but her father's death seems to have made that tendency even stronger. However, as she and the main character get to know each other, her expressions change slightly, to the extent that only her sisters can tell.

The matriarch of the Sagara family. She is a widow whose husband died shortly after the birth of her fourth daughter, Ruruka. She is mentally strong, having raised four daughters by herself. In terms of personality, she is very open and easygoing. She thinks of the main character as her own son, and because of this, she is sometimes very defenseless towards him. She is still very much in love with her late husband. Sexually, since the death of her husband, she has been in a state of abstinence, and in reality, she has accumulated quite a lot of sexual desire (although she is not aware of it...).
