Instead of going home, Kayo has spent the last few days in a disused school bus while being supported by Satoru and the others. Only Sachiko and Yashiro begin to realize that something is going on when they observe changes in Satoru’s behavior.
After being "missing" for three days, Kayo returns home. Her mother, Akemi, sees Satoru and Sachiko standing a few paces behind... Will Kayo be safe at last?
