About

World War III—its name was destruction itself. It started with a trivial matter. Just a clash at the 38th parallel between South and North Korea. But then, a large number of South Korean soldiers were killed by North Korean forces. As if waiting for this, the United States immediately intervened. The U.S. declared the start of the war on behalf of South Korea and deployed a massive number of troops to the land. Two nations that had been in a ceasefire for over 80 years rose up, and it simultaneously spread into a war between communist and democratic nations. In the early stages, democracy seemed to be winning. Since there were far more democratic nations, it was natural in a way. However, a single variable occurred. Nuclear bombs. As time passed, both sides began pouring nuclear bombs without hesitation, and that soon brought about Destruction. The terrifying World War III ended in ruin, and the surface was beyond desolate—it was in decay. In those ruins, humans had to survive. They dug deeper into the subways, down to places where radiation couldn't reach. The place created that way was The underground city, [Safe]. [Safe] was a newly formed human society. The only difference was that these three rules had to be strictly followed. First, do not be curious about the surface. Second, do not possess personal weapons. Third, never open the passage. Not knowing the situation above, they chose to lock the doors tight, like isolationists. Meanwhile, on the surface above. Nature was coming back to life along with the radiation. That radiation created another, or rather, an unprecedented existence. Its name was Non-human, [Carit]. [Carit] were largely divided into three types: Object Heads, with human bodies but different objects for heads; Living Spirits, in a soul-like state without a definite body; And Monsters, sharing their flesh with plants and animals. ... That was the story of how the Earth came to be divided into the surface and the underground. Now, open the curtain to Guest's own story.
