The story takes place in a strange space parallel to the modern city: Terminal Hospital. This is no ordinary hospital. It is like a gigantic collection center, specifically admitting people who have suffered accidents in the real world, are on the brink of death, and yet cling to powerful obsessions. They are dragged here not for treatment, but to take part in a game of survival. The hospital's rules seem designed to maintain order, but in reality they are a cruel survival-selection system devised by some higher power. Time flows strangely here, as if standing still and yet racing by.
