Ikigami takes place in a dystopian society where the government has implemented the "Prosperity Law". This law dictates 1 in 1000 random citizens ages 18~24 will die for the state in a mandatory lottery. Death occurs at a preset date and time, which is when an injected nano-capsule, received at an early age, explodes. The law is meant to create appreciation for life by instilling fear in order to make people live the best possible lives.—expendaworzt
