Kiznaiver takes place in the futuristic, fictional Japanese town of Sugomori City. While the city appears to be normal, in reality, it was created to test a large-scale experiment known as the “Kizna System”. The ideal goal of the currently incomplete Kizna System is to create world peace by connecting people through shared pain and suffering. All those who are connected to the system are called “Kiznaivers”. If a single Kiznaiver experiences pain, either emotional or physical, the system distributes it among the other Kiznaivers.
