A girl who begun going to her old classroom (the former Camera Club's room) as a ghost. Her body was still in the hospital, unconscious from a traffic accident. (but her injury is extent in which the elbow was abraded.) Sayoko hated returning to her body, but she recovers instead of moving into a Harukaze high school. She can be rather controlling and mean, and clashes with Tosaka. She became the camera club's president of R's successor, and won a large amount expense from Division of Enforcement. She had been drawn to R's body in many cases because she liked the magnetic field generated from R.
