Ganji and Suzu, who are part of the Hondo Metropolitan Police "God Weapon Control" Division, get sent to investigate why a certain island off the coast of Japan has gone dark! When they get near it, they discover why—a giant "lid" has covered the entire island! Is this the work of a nefarious criminal, or simply the wrath of God punishing the island-dwellers with indefinite isolation?
