Since depressed people exist throughout the world, the Juden-Chans - shapely ladies from a parallel world - use their special powers to help charge up the mentally dejected and also earn a living in the process. While doing her job, Plug, despite wearing her stealth suit, discovers that unlike other humans a teenage boy named Sento can actually see her, which Aresta later learns, as Sento uses a baseball bat on Plug and her if they startle or irritate him.
