At that time, Furo Hikaru was informed that her junior police officer had reported a bus jack. However, there are no problems with local buses and sightseeing buses. Bath light talks to Aoto and others, but she is dismissed as she is just a prank.The bus with the train stops at the park, and Otoya sends the passengers to the bathroom one by one. The first person to go to the bathroom thinks about how to contact the outside. Sei, who had been informed of the contact information by Ikemoto before leaving, wrote down the current situation on a memo paper and placed it in a place where the criminal could not find it.
