One day, Zeha wakes up in a hospital bed with a nasty wound on his chest and no memory of what happened. Before he can get his bearings, a city detective reveals that he was found collapsed on Inwang Mountain, the sole survivor of a grisly mass murder. This was only the beginning. The Beom, monstrous entities from another world, stalk the streets, mauling and devouring anyone they can find. When Zeha learns that he is somehow at the center of it all, he decides to stand up and fight. But first, he will need allies— a team of seven individuals drawn to each other, as if guided by fate itself.
