From the world, parallel to the normal human world, women, known as "Yuden-Chan" (girls-movers) patrol the human world in search of people who feel depressed and unhappy. These people are classified from A to F, being normal f and close to suicide. When judden-chains find targets with a range of C or higher, they charge these people with electricity to improve their mental states. Although it is usually not visible by human eyes, one of these Jūden-Chan, Plug Cryostat, accidentally meets a young man who can see her, because he pointed to his sister (his father in manga). This series revolves around a variety of outcome between the main characters and the desire of this Jūden-Chan to improve itself. ~ Very funny manga and anime wiki. I would like more people on him. Well, it is clearly a little and of the other.
