Join in more adventures with Madoka, the boy who can see dead people, and GSG, the agency that helps them to cross over to the other side. After a high school teacher dies before teaching her very first class, Madoka lets her take temporary possession of him so she can experience what it's like to actually teach. Then the ghost of a pretty but fatally frail high school girl enlists Madoka's help to take revenge on a former classmate: GSG agent Aguma!.
