Yuuma Kousaka, a high-schooler resistant to the zombie virus, has found himself in a situation where he has to periodically kiss Mai Tsukishiro to stop her from turning into a zombie. They come across two more survivors-a pair of college girls-and Yuuma tries to hide Mai's zombification from them. However, after they see the pair, Yuuma and Mai are forced to keep up the façade and pretend to be in a relationship…something that his real girlfriend, Hinata Hyuuga, does not find entertaining.
