The second game in the Jake Hunter/Tantei Jingūji Saburō series, this time on a regular Famicom cartridge. A girlfriend goes missing, and the search for her reveals that she was hiding guns. Police suspect a link between the case and an underground trafficking organization. Like other Famicom entries in the series, time plays an important role. Any action the player chooses uses a certain amount of time. Failing to solve the mystery within the allotted timeframe results in a bad ending. Commands are chosen from a set of several, like many Japanese graphical text adventure games. Because this game is on a cartridge rather than a Disk Card, progress is continued via passwords rather than save files.
