Famicom Detective Club: The Two-Case Collection brings together remastered versions of both Famicom Detective Club games originally developed by Nintendo R&D1. The Missing Heir (1988): an amnesiac detective's assistant investigates the death of Kiku Ayashiro at the Ayashiro estate in Myoujin village, uncovering how an old family legend connects to a string of murders. The Girl Who Stands Behind (1989), a prequel: a teenage runaway becomes the assistant of private detective Shunsuke Utsugi and investigates the murder of a schoolgirl named Yoko Kojima at Ushimitsu High School—aided by Ayumi Tachibana and Hitomi Kawaii, in a case entangled with the urban legend of a ghostly figure that stands behind students.
