"Bonder" is an original Japanese TV animation produced by the animation company TRIGGER Co., Ltd., and the production decision was announced in October 2015. The story is set in the fictional Japanese city of Sugo City, which was built on the land of pioneers and has a sharply reduced urban population. A high school student named Kappei Agata who lives there has a body that cannot feel pain for some reason. One day when summer vacation is approaching, Kappei learned that he has been selected as a member of the pain-sharing system "Bonder" through the guidance of the mysterious girl Sonozaki Houko. Sonozaki said: "This is an experiment to lead a world full of disputes to peace." So, the boys and girls who bear each other's pain began this summer's story!
