Monzo Kobayashi is a dime-novel writer. He goes to see the stage of Ranko Mizuki, a star of an all-girls'-operetta company known as Asakusa Revue. Monzo notices a creepy man sitting beside him who keeps his head slumped down and does not even look up when Ranko appears on stage. On the way home from the theater, Monzo encounters another creepy situation. A dwarf (inch-high samurai) with a child-sized body and a grown-up's head passes right by him and is carrying a woman's arm that has been sliced off from the shoulder. Being a writer, this strangely enhances his interest of this dwarf and he begins an investigation about dwarfs. At the same time, his old friend Yurie visits him. Monzo secretly has a crush on her but knows that she is married to some one else. Yurie asks Monzo to introduce her to his friend, the detective, Kogoro Akechi. Monzo agrees to this and takes her to Akechi's apartment. When Akechi tells them about his current investigation, Monzo surprisingly finds out that Ranko Mizuki has disappeared. However, this is just the beginning of a bizarre twist that is going to occur one after another. Monzo and Akechi's challenge to solve the mystery begins.—Division 1656
