Kazama, Ushio

風間汐

Ushio is the protagonist Sumika's best friend and has always been so, remaining oblivious to Sumika's feelings for her (although she does at one point recognize that Sumika is in love and even feels guilty for not realizing it sooner; she simply does not understand that it is her whom Sumika feels that way about). Ushio has made it clear that Sumika is not her type; Ushio's "type" consists of a cute, small, and feminine girl who is innocently curious—the kind one would want to protect—and Sumika falls far from into that category.
Ushio is constantly falling for girls like that, only to find her crushes unrequited again and again, leaving Sumika to end up consoling her when her heart breaks. She wishes just once that she could find a girl who would return her feelings. Her spirits are lifted, however, when a lesbian couple in her class forms the Girls Club for women interested in women, with her and Sumika (and her straight friend Kiyori, who goes along with the idea to make the necessary number of people needed to form a club).
Ushio lives only with her brother (a yuri novelist, ironically enough); her parents, she says, are "gone," and her place is a mess because of this. She seems to have gotten over what happened, for the most part, in the story.
