Kiznaiver

The story takes place in Sugomori City, a fictional Japanese town built on reclaimed land. As time passes, the city's population slowly dwindles. One day, Noriko Sonosaki informs her classmate Katsuhira Agata, "You have been chosen as a Kiznaiver." The Kizuna System links Katsuhira to other classmates with vastly different lives and personalities, forcing them to share each other's wounds. This experimental system, meant to foster world peace by connecting people through pain, labels its participants as Kiznaivers. Whenever one of them is hurt, the system distributes the injury among the rest. The lives of Katsuhira and the others unfold in this fading town.
