There is a zombie outbreak in a Japanese city. Things are going downhill rapidly. One young man plays a videogame with an English speaking zombie hunter. Soon he and his fellow residents are fighting numerous zombies in the real world. And the living dead have quite an appetite. The zombie outbreak spreads rapidly. It seems to have a supernatural origin. The key to stopping them seems to fall primarily to an old man. But a new hero emerges in the form of a high school girl who takes up a warrior's taks to fight the zombies. She somehow ends up with the arm of the zombie hunter from the videogame. She and her grandfather (the old warrior) eventually face the master demon.
