The story revolves around a female thief named Chico, who is the spiritual successor to the Kaijin Nijū-Mensō (The Fiend with 20 Faces) thief character created by famed suspense and detective novelist Ranpo Edogawa. (Edogawa is a pen name for Tarō Hirai; when written in Japanese family-name-first order, it spells out a Japanese pun for the name of the American suspense and detective author "Edgar Allan Poe").
