Yōko Nishikawa

A girl in the same grade but different class to Futaba and Teru. She was raised in a rich family, but before the story starts, her mother died and her father's enterprise went bankrupt; as a result, she has to lead a frugal and ordinary life on her own, while she still speaks and behaves with the demeanor of a noble girl, and still longs for her previous rich life. She was very lonely since that misfortune, until Futaba and Teru run across her at the start of the story, and befriend her. Her given name means "leaf child".
