In the near future world, three months after the sudden outbreak of the zombie virus, human society has completely collapsed.
The story begins in an abandoned coastal city. The once bustling business district is now covered with wreckage and bloodstains.
A virus called "Blood Eclipse" sweeps the world, causing infected people to lose their minds and develop a craving for cannibalism. After death, the protagonist acquires the ability of "memory retrospection" and retains the memory of his past life and is reborn until the early stages of the virus outbreak.
