Kyouran Kazoku Nikki狂乱家族日記; Kyōran Kazoku Nikki

A thousand years ago, Enka, the god of destruction, died leaving a prophecy that its "child" would one day destroy the world. In order to prevent this, "Operation Cozy Family" is implemented in which the children who are potentially prophesied as the "Child of Enka" are forced to live together. This impromptu family contains all children, human and otherwise, as well as an official of the bureau and a self-proclaimed goddess who act as the parents of the household. The goal of "Operation Cozy Family" is to discern who the prophecy applies to, as well as to teach them all about the love of family in hopes of convincing the "Child of Enka" not to destroy the world. But with all families, there''s bound to be mishaps and adventure - especially when the fate of the world is at hand!
