Highschool of the Dead

Synopsis

With the apartment cleared, the girls refresh themselves in the bath while Takashi and Kohta check the weapons and ammunition in the household. Meanwhile, the police at the blockade are coming under pressure from both the zombies and the civilians trying to escape them, including a group of protesters led by a conspiracy theorist who believes the epidemic is a biological weapon of the US and Japanese governments. With no help coming from headquarters, the police are ordered to use deadly force to maintain order at the blockade. Back at the apartment, Takashi has to deal with Rei and Shizuka, who are both drunk. After an argument between them, Rei starts to come onto Takashi, but he holds her back. Just then, a dog, later recognized as Zero, starts barking outside, which starts to attract the zombies.
