Kuroto Nakano is a young salaryman with a very unhappy and stressful life, almost entirely occupied by his job at the company for which he works. One night, after yet another day spent overworking, the moment he opens the door of his home he finds a seemingly young girl with fox ears and a tail cooking dinner for him – her name is Senko, an 800-year-old fox-demigod. Senko has been sent to Earth from the spirit world to relieve Kuroto from his unhappy life and help him find happiness again.
