FUJIMIYA KAORI
Kaori is Yūki's classmate who choose to not make any friends as she would forget memories concerning friends every week. She used to be popular in school, but has since experienced a car accident that affected her memory. She decides to keep a diary after it was suggested by Yūki to record her experiences. This helps her to become more and more familiar with Yūki, to the point of just barely remembering him. She had made a promise to meet up with her childhood friend, Hajime Kujō some time in the past but was unable to because of the accident. Her mother suggests that to an extent, she may be repressing her own memories. She is quite good in mathematics as compared to Yūki, and often helps him with his studies.
