Synopsis
The game is a standard command-style adventure. The player chooses from a set of text commands to interrogate, examine, or move from place to place. The setting of the secluded mansion gave the game a tense and horror movie-like atmosphere which was well received by fans. The original FDS version requires the player to switch the Disk Cards midway through the game, but the GBA and Virtual Console versions can be played without such interruptions.

Plot
The scenario was written by Toru Osawa and Nagihiro Asama, based on the concept by Yoshio Sakamoto. The story begins with a man named "Amachi" discovering the fallen protagonist on the ground near a cliff. The protagonist discovers that he has lost his memory, and after recuperating, he revisits the cliff and meets a young girl named Ayumi Tachibana. He learns from Ayumi that he is an assistant detective investigating the death of Kiku Ayashiro, and heads over to the nearby Ayashiro estate located in Myoujin village. The Ayashiro family owns a huge plot of land passed down from generation to generation, but there is a strange saying in the village that the dead will return to life to kill anyone who attempts to steal the treasure of the Ayashiro family. As the protagonist investigates the mysterious death of Kiku Ayashiro, he discovers the terrifying connection between this saying and the serial killings which take place.
