The "most terrifying" housekeeper is back to clean up Japan's dirt! This time, Mitadaen (Masahiro Matsuoka) will lead the new housekeeper, Sakura Daimon (Rinka Kumada) from the housekeeper agency. Her father is a criminal police officer, and her mother is a member of the Science Research Institute. She grew up in such an investigative family, and has been accustomed to reasoning and solving puzzles since she was a child. She has a side that will make her delusions and imaginations swell into cases even for the slightest changes. "Investigation is making money with your feet", with the young and enthusiastic side of the Showa era, she embodies the image of a housekeeper that has never been seen before!
