Not at Home

Initially, two hundred years ago, the "Mist" appeared... The fog is mysterious and terrifying. It grows silently like a living creature. Like a hungry glutton, it swallows up all the villages, towns and even countries it touches, along with the ocean, earth and sky, until the whole world becomes chaotic and unknowable... Creatures as powerful as gods began to appear one after another, either standing in the cities of human survivors or walking in the vast sea of mist. The surviving humans were surrounded by mist, as if they were humble ants trapped on an isolated island... Until a group of people decided to go deep into the fog to find the truth behind the fog, they became "non-returners".
