The Diary of a Crazed Family

The Great Japanese Empire Paranormal Phenomena Bureau of Measures, led by Midarezaki Ouka, is responsible for investigating paranormal cases. Ouka's life is disrupted when he encounters a cat girl stealing apples in the shopping district, prompting him to initiate Operation Cozy Family. This operation involves reuniting and rehoming potential children of Enka, the God of Destruction, who was prophesied to destroy humanity after its death thousands of years ago. The potential children, including Teika the lion, Gekka the jellyfish, Yuuka the oni, Ginka the cross-dressing mafia son, and Hyouka the bioweapon, are placed in a mixed family with their parents Ouka and Kyouka, ruler of a demon underworld.
