"The Personal Information Trap" is the third chapter of Volume One.
Madarame Baku visits Kaji Takaomi's home. There they find a 1-month overdue porn DVD and its receipt. They go to the DVD store; while Kaji just wanted to return the video, Baku requests to talk to the manager. Baku claims the store has been selling their customers' personal information. The manager is called, and the store is about to call the police, believing that there is no concrete evidence. However, the chief sees, by the reaction of his employee and the signatures Baku has, there is evidence enough to prove that the store has been selling personal information. Instead of calling the police, Baku and Kaji receive a compensation fee of two million yen and free DVD rentals.
