An unknown pandemic has flooded Japan and is on the rise of causing Havoc among humanity. Although this lethal disease is unknown, the way it is passed on is deadly. Those who get bitten by 'them,' die and come back as a zombie and feed on the flesh of living human.

Meanwhile in Japan, a group of high school students and a school nurse have joined forces, to escape the already contagious Fujimi High School, in their attempt to investigate who or what was responsible for this plague.

Along the way, the group saves a young girl and a puppy from the clutches of death, whilst trying to find their families.

Friendships and allies will be made; lives will be saved and lost; hearts will be broken; and love will be found. However, can the group, with a doctor, swordswoman, strategist, gunsman, a noble puppy, a young girl, a fighter and their leader survive through the wreckage of hell, or will they all slowly fade away and become one of the billions of people among the dead?
