Beginning on the 4th day after a zombie virus has broken out, this is a story about the will to live, human instincts and our selfish desires. A thrilling tale about the survivors of a zombie apocalypse.

The story begins with Jingook Yeo being stuck in his room after his mom became a zombie. With food and water running out, he ponders his fate.

The story begins with Hideo Suzuki, a 35-year-old manga artist assistant, whose life seems to be stuck around his exhausting but low-paying job, unfulfilled dreams, strange hallucinations and unsatisfying relationships. He sees himself as a supporting character in his own life, and has low self-esteem, resulting in frustration.

One day, the world as Hideo knows it is shattered by the presence of a disease (nicknamed ZQN) that turns people into homicidal maniacs who resemble and behave like zombies, and whose first instinct is to attack and devour the nearest human. Armed with only his sporting shotgun, he runs for his life, meeting strangers along the way. For a while, he and his companions struggle to stay alive, while questioning their moral choices. In the end, only three of them remain and drive all the way to the top of Mt. Fuji to be saved.
