桐ケ谷 栞里

She is a female student in the track and field club. She doesn't try to get involved with other people and listens to music on her headphones during breaks. During club activities, she simply goes through her own training without much effort. She is not so obsessed with her own records. She is a childhood friend of Yua and the only one with whom she has a close relationship. She has a kind of protective desire only for her. She has no interest in sexual matters either. However, as she continues to have "kinky" relationships, she begins to develop a proclivity for sexual acts that she is unaware of. [From official site]
