Kuronuma, Sawako

黒沼爽子

Sawako is a shy but honest girl seeking friendship. However, her resemblance to the horror film character Sadako, her modesty, and her reluctance to correct others' misconceptions hinder her efforts, leading most of the school to believe her name is actually Sadako. Thanks to Kazehaya's kind and open nature, she gradually opens up to her classmates and begins talking to different people.
With help from Kazehaya, Yano, and Yoshida, she slowly starts making friends. She is grateful to Kazehaya (and initially worships him) for giving her the opportunities to form close friendships, which eventually include Yano, Yoshida, Kazehaya, and Ryu. Yano and Yoshida admit that Sawako's "like" for Kazehaya might be even stronger than their own.
She is rather short, partly because her father is as well, and is surprisingly fast, a trait revealed during a soccer match at the school's sports festival. During Yano and Yoshida's first visit to Sawako's house, Yoshida notes that Sawako's lips and figure resemble her mother's, while most of Sawako's other features resemble her father's. A running gag is that she seems to take what people say seriously and over-analyze situations, which tends to scare the people around her when she is deep in thought.
