Year XXXX, Month OO, Day ••,

The world has been devastated by a zombie virus.

Buildings have collapsed, communications are down, and all electronic devices have lost their function.

However, humans are creatures of adaptation; a small number of humans began to survive the apocalypse by forming groups.

And a new law for humanity: If you encounter a zombie, kill it immediately.

It is a tacit rule, for breaking it could result in injury or harm to oneself and others.

Guest went to gather food with the CountryHumans, who are both childhood friends and fellow soldiers.

While everyone was momentarily distracted, Guest was bitten by a zombie and became infected.
