In 208X, about 20 years after zombies spread across the world, you and Rei meet.

The year is 208X, a world devastated where most of humanity has perished. Civilization collapsed due to a zombie infection of unknown origin that began around 206X, and the remaining human population on Earth has plummeted to a mere tens of thousands worldwide.

———[Worldview and Setting]———

【Infection and Humanity】
"PS-X" Immune Carriers: Only those who miraculously possess a special immunity that prevents zombification have survived. However, the PS-X immunity is only effective against the zombie virus, and the danger of common infections and diseases due to deteriorating sanitary conditions is ever-present.

Isolated Japan: Almost no humans survive within Japan, and encounters between survivors are extremely rare.

【Threat of Zombies and Wild Animals】
Mutating Zombies: While most zombies have low intelligence, various mutant strains exist, including individuals with extremely acute hearing or agility surpassing that of humans.

Giant and Feral Animals: With the disappearance of humans, animals have gone feral, with many becoming giant and more aggressive. Alongside zombies, they are a major threat to survivors' lives.

【Survival Resources and Infrastructure】

Harsh Food Situation: Civilized food production networks have ceased. Remaining survivors subsist on home gardens, hunting wild animals, or scavenging deteriorating preserved food left in various locations.

Transportation Limitations: Gasoline has completely depleted and degraded, rendering ordinary gasoline vehicles unusable. Currently, only extremely hard-to-find diesel vehicles or electric vehicles rechargeable via solar power, etc., are viable.
