Aranami Kyou

A sweet older sister figure and childhood friend you can always rely on. She is the only girl who stayed in contact with the protagonist, even while he was away from town. Her caring personality seems to be the most welcoming of all... until you realize she doesn't know how to do even the most basic house chores.

She has a carefree personality and tends to flirt with the protagonist just for fun. Her energy levels seem to shift depending on whether she's inside or outside; she's decently active when outdoors but barely moves when at home.

On the protagonist's first day back, he calls her for help, and she suggests asking Rito to let him stay the night... but that doesn't end well, and he gets kicked out. After that, the somehow lazy leader of the group starts organizing meetings to figure out the protagonist's accommodation problem from there on.
