Juden Chan

From a planet called "Life Core", which exists parallel to the normal human world, females known as "Jūden-chan" (charger girls) are patrolling the human world in search for individuals who feel depressed and unlucky. Their job is to charge these people up with the help of electricity in order to improve their mental states. While normally unseen by human eyes, one of these Jūden-chan, Plug Cryostat, accidentally meets a young man who is able to see her, because she was targeting his father (his sister in the anime). This series revolves around the various antics between the main characters and the quest for this Jūden-chan to improve herself.
