One of the students who survived the bus crash. Sanada helped rescue others from the bus before it burst into flame. Before the bus burst into flames, Sanada found Toono still alive and conscious. He could not save her, as she had a piece of metal stuck into her body, so Toono asked him to kill her so she would not have to burn to death. As Sanada did as Toono requested, he thinks he is one of the three murderers.
