Misaki Sogoru

She is Kyo Sogoru's younger sister and a middle school student. She has a somewhat strong-willed personality. In the final episode, she appears within the memories that Kyo Sogoru had forgotten. Her surname became the basis for Shizuno Misaki's surname. The name of the upperclassman whom she said Kyo Sogoru had a crush on is the origin of Shizuno's given name, but it is unknown whether that name is a first or last name. In the promotional video released before the broadcast, it appeared that she had transferred to another school.
