A quiet, gentle, nondescript girl. However, she’s quick-thinking and has a strong sense of self. She enjoys sewing and crocheting, and has a tendency to get lost in her own little world. When Mikoto asks her out, she senses something guarded about her that intrigues her. Although she doesn’t understand Mikoto’s true intentions, she decides to do her best to make things work between them. Aoi seems to like her and often talks to her, but she doesn’t know what her intentions might be, either.

Mikoto’s younger sister. She’s been sick from a very young age. When at school, she spends most of her time in Infirmary Room 2, studying on her own, although she’s often absent from school altogether due to hospitalizations and appointments. Since no one else spends as much time in the infirmary as she does, she treats the room as her own, decorating it with her personal things. She usually has her nose in a book and, having had to grapple with her own mortality, has a more mature personality than her elder sister and a more philosophical outlook on life.
