Shiori Misaka (美坂 栞 Misaka Shiori?) is a first-year high school student and is Kaori's younger sister. She has suffered from an illness since birth, which has caused her to become very physically weak, and she is almost always absent from school because of it.

Shiori's theme is Egao no Mukōgawa ni ("Another Side of a Smiling Face").


Shiori is frail-looking with 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 is a very polite, somewhat shy, and kind individual, but also 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.

As rough as her life is, Shiori has forced herself not to cry, no matter the situation. She instead hides her real emotions behind a happy and optimistic façade. She often lies about just how severe her sickness is, claiming that it's nothing more than just a common cold.

She dislikes causing trouble for others, and even admits that she had tried her best to not allow Yuichi to get close to her, as she knew that her worsening condition would only cause him pain.

Despite the struggle that her condition causes her, she had accepted her fate a long time ago. Only when Yuichi got involved did Shiori truly value her life, and not want to pass on before she was able to do more things with him and the new friends she had found in the people Yuichi had introduced her to.

Shiori longs to be treated like any other normal person despite her severe illness, and also wants to once again be close with her older sister, who started to avoid her once she learned of Shiori's fate. She longs for the times they used to have before Shiori's state worsened, and wants to have more memories with her.

She has also been proven to be a very stubborn individual, even going against her doctors orders to wait outside of the school every day instead of resting. Even with Yuichi constantly pestering her to stay at home, she insists on visiting the school every day.

Trivia Edit

  • She has been proven to not be able to handle spicy food well.
  • Shiori is the second shortest of the main characters, only taller than Ayu.
