Shiori's Mother (mother)
Shiori Misaka (美坂 栞 Misaka Shiori ) is a first-year high school student and is Kaori Misaka's sister. She has suffered from an illness since birth, which has caused her to become very physically weak, and is almost always absent from school because of it.
Her theme is Egao no Mukougawa ni (means "Another Side of a Smiling Face).
Shiori is a frail-looking young woman who has a light complexion and blue eyes. She has short, straight brown hair that comes down to her neck. She usually wears a woolen white jumper underneath a brown checkered shawl. She wears her school socks which are black and knee-high, as well as black school shoes.
Shiori loves drama and is always inventing reasons for things that happen in her life, but the real-life drama of a sister who denies her and a life threatened by illness is encroaching on her. While she was sick her sister ignored her, so she stayed out of her way.
Sick as she is, Shiori thinks nothing of sitting outside the school for hours on end while eating ice cream in the middle of winter, despite Yuichi telling her several times to go home and rest.
Due to her illness, it is not strange for her to carry around an array of different pills and drugs for her many ailments. She has a noticeably quiet voice. Shiori informs Yuichi early on that the reason she disobeys her doctors' advice and comes to school so frequently is that she wants to meet someone she knows.
- Shiori actually makes her first appearance in the first episode as a cameo, conversing with Kaori in the background.
- Her name (栞 - Shiori) literally means "to remove", "to discard" (the word can also be written as "删" (shān) in Chinese).
- She is the only main character who did not have any interactions with Yuichi Aizawa in the past.
- She has been proven to not be able to handle spicy food well.
