The survivors are shocked to learn that the zombie pandemic has spread worldwide. After encountering another group of survivors, Takashi tests a theory on avoiding the zombies based on how they can only react to sound. However, when one of the survivors accidentally makes a sound, they have to fight through a horde on the way to the bus, losing some survivors in the process. When they spot another group of survivors approaching, Rei recognizes one of the teachers, Koichi Shido, and is hesitant about letting him on board. After breaking out of the school, Rei becomes defiant about Shido appointing himself as the leader and runs off the bus. As Takashi goes after her, a bus filled with zombies crashes and traps them in a tunnel, forcing them to meet up with the other survivors later. After defeating a zombie motorcyclist, Takashi and Rei find its motorcycle and head towards the city.
