Highschool of the Dead

Synopsis

As two other survivors, Saya Takagi and Kohta Hirano, try to avoid the zombies, Rei tries to contact her father, who tells her the city is in complete chaos before being cut off. Meanwhile, kendo club president Saeko Busujima saves the school nurse, Shizuka Marikawa, from more zombies. Kohta manages to piece together a nail gun, while Takashi and Rei manage to stop the zombies on their end. As Kohta runs out of ammunition and Saya starts to buckle under the pressure, the other survivors join them to take out the zombies. As they make plans to journey to Takashi's house to check on the safety of their families, they learn that the outbreak is much worse than they thought.
