The countryside is overrun by zombies, with only a few pockets of survivors just scraping by here and there. One such person is Aya, the next to the last member of a clan gifted in the ways of the sword, who thusly handles the undead with relative ease, though she has her sights on her younger sister, Saki, for the murder of their father.
By Aya’s side is Katsuji who has had similar hardships; his kid sister has been kidnapped by the evil D3 corporation and the zombie it’s created, and he too is out for revenge. Later they meet another ass kicking lady shows up, Reiko, who wages war with a sawed off shot gun. After the zombies are done away with, they immediately set their sights on each other. But Aya’s cowardly and bumbling, yet lovable assistant Katsuji manages to convince each other that they’re all fighting for the same thing, and a truce is formed.
