2074, The World Ended.

The moon and sun were broken, resulting in a perpetual white night, and days of sleeplessness followed.

Then, an unknown virus caused the Whitening phenomenon, where everything mutated into white.

People called the transformed plants and animals Baeksa (百事). Regardless of whether they were plants, animals, or humans, once infected, their entire bodies turned into white monsters.

Once transformed into a Baeksa, there is currently no way to return, and they turn into grotesque monsters, losing their original form. Infected plants mutate into white, fern-like growths that spew the virus, while infected animals and humans become white, four-legged creatures with large, mantis-like forelimbs, losing their sense of self and attacking all living things.

It is now 2077. Three years have drastically changed the survivors.

The world has completely abandoned the systems of society and law, replaced by rampant violence and power. Survivors constantly fight to secure the few remaining supplies.
