Sayuri Kakinuma

Sayuri Kakinuma is a student of 9th Grade Class 3 in 1998. She is a shy, mature and studious girl, who loves to read books, but not to socialize. She is usually seen reading a book, as well as going to the library. She was present during Mr. Kubodera's suicide, an event which was traumatic enough for her to miss a few days of school, as she didn't appear for several episodes. She is later seen in the class trip, not smiling in the group photo. In "Makeup", she heard Takako's broadcast, and along with Matsuko tried to confront Kouichi, though they were unable to prevent him and Mei from escaping.
