Sagara Emiru

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.

Spoiler

She secretly enjoys cosplay but is too afraid to tell anyone about it because she think they will look at her differently.
