Sakagami Shuuichi, a member of the school newspaper, is asked to gather information about the school's seven mysteries. He meets with six other students after school to listen to their stories. This game is a visual novel adaption of the two novels "Gakkou de Atta Kowai Hanashi" written by [url=https://vndb.org/s11627]Iijima Takeo[/url], published by Aspect inside the Logout Bouken Bunko label, and released around the same time as the Super Famicom game [url=/v745]Gakkou de Atta Kowai Hanashi[/url]. As such, it has the same characters but different stories. It is Apathy Series's first work whose epicenter is Narugami Gakuen. Being a doujin game not published by Nintendo, its plot is far more violent than the SFC game. The original release features the novels' content with no branches, and an additional scenario called "Emi-chan no Sakagami-kun Kansatsu Nikki" (Emi-chan's Sakagami Observation Diary), which has height different endings. It is, so to speak, a prelude to the main story of [url=/v747]Apathy - Midnight Collection ~Vol. 1~[/url], "Emi-chan no Satsujin Club Kansatsu Nikki" (Emi-chan's Murder Club Observation Diary). With the permission of [url=/p227]Banpresto[/url], the game used [url=/v745]Gakkou de Atta Kowai Hanashi[/url]'s OST, after rearranging it. Different versions were later released which added, replaced or removed content.
