Kiznaiver

In a fictional Japanese city called Sugomori City, a group of students find themselves entangled in an experimental peace-keeping program known as the Kizuna System. When Katsuhira Agata is unexpectedly selected to be a Kiznaiver by his classmate Noriko Sonosaki, he is connected with several other students whose lives and personalities differ vastly from his own. This system allows them to share each other's physical pain as wounds are distributed among the group, fostering empathy and unity in the process. Sugomori City, a metropolis built on reclaimed land, experiences a dwindling population over time, creating a backdrop of gradual change against which Katsuhira and his fellow Kiznaivers navigate their shared experience.
