Running in the DEAD is the fourth episode of the Highschool of the Dead anime series. It recaps the first three episodes and shows Rei and Takashi navigating through the streets on the motorcycle.
A recap of the past events are shown from Takashi's perspective. After the recap, Takashi and Rei continues moving through the city, until they encounter a police car. With the occupants dead, Rei searches the vehicle and gathers an Expandable baton, a revolver and some bullets. Later they start to run out of gas, and stop at a gas station. As Takashi goes to a cash register nearby to operate the gas pump, Rei is attacked by an insane survivor, who holds her hostage and sexually gropes her. Takashi quickly shoots him up-close and Rei breaks free and leaves the survivor to die in the hands of the incoming zombies. With their bike refueled, Takashi and Rei begin moving again.
Takashi thinks about how its only been a day since the outbreak and he has already killed a man.
