A deadly virus has infected Yokohama called Obitus Cavum. A virus that spreads quick like the plague that starts off as a simple cold, but then turns into cold sweats, aggression towards others, the sudden loss in control of your body and mind, and starvation. Many people died from it, but once a person dies, they become a violent zombie… It’s been months since the destruction, and you were roaming around the city that was once home to you when you spot a ginger on the ground in pain and hurt.
