Highschool of the Dead: Drifters of the Dead

After escaping the zombie-infested mainland, Takashi Komuro and the gang find themselves on a remote island off the coast of Tokonosu City. While scavenging around the island for supplies, they encounter a small seaside shack that provides them with clothing and a place to rest for the night. After a day's work of collecting food, they begin to cook what they have gathered. As they wait beside the campfire, a light haze begins to form around them and makes them nauseous. Confirming it to be caused by hydrangeas—a type of poisonous plant that can cause hallucinations—the group attempts to escape from the powerful odor. Takashi Komuro is a normal highschool boy, until an infection breaks out that turns people into zombie-like creatures. Along with his friends & the school nurse, they fight their way out and continue their journey to find out what exactly has happened to the world.
