Hong Kong City was located in Asia with over 7.4 million people of various nationalities in a 1,104-square-kilometre (426 sq mi) territory, Hong Kong was one of the most densely populated places in the world.
When the first sign of Doomsday appeared three months ago, the society of Hong Kong City immediately descended into chaos. People went to the hospitals, the streets, the malls, each with their own agendas. Tensions were high at all times; there were even moments when people went out on the streets and fought with one another, blaming or defending the government and such. The government had tried to put back stability but due to the tense situation, some people didn't listen, rioted and even attacked the police and military. Tension grew, and some people hid in their houses. But as the dead rose up, many people regretted their decisions.
