Although her father was a great magician, Yamada Naoko is merely a competent magician who utterly lacks showmanship. She has a hard time making a living, and is constantly behind on her rent. That's where Ueda Jiro comes in. Ueda is a professor of physics who is also an author of books debunking the psychic and supernatural. People with problems of a supernatural nature seek out his assistance. But who ends up doing most of the work? Yamada may not be the best magician, but she has a genius for seeing through other people's "tricks," and Ueda uses this to his advantage. Their strange and often very funny partnership is the real reason people get hooked on this series.
