Shiori's Classmate  

She first appears meeting Yuuichi after he met Shiori in school one day. She told him about Shiori being in school for the first day only to faint out. She is also the first person Shiori meets and talks to during the first day in school. Ever since Shiori fainted in school, she has been worried about her. She is the one that gives Yuuichi hints that Shiori is actually Kaoris younger sister. She is invited to attend Shioris birthday party as well.
