is a visual novel produced and published by Chunsoft. Marketed by the company as a "sound novel" rather than a video game, it is the progenitor of the developer and publisher's sound novel series and of the format of electronic entertainment now usually known generically as a visual novel. Koichi Nakamura conceived the title after showing his work on the Dragon Quest role-playing video games to a girl he was dating. On finding she did not enjoy them, he was encouraged to make a video game that he described as "for people who haven't played games before." Influenced by the early survival horror game Sweet Home, he developed it into a horror-themed interactive story. The game sold over 400,000 copies in Japan, including over 300,000 copies for Super Famicom and 100,000 for PlayStation. It was later adapted into the film St. John's Wort. A sequel, Kirigirisō, was released in 2016, produced by Spike Chunsoft and serving as a crossover with and prequel to the Danganronpa series.

Although she tried playing the games that Nakamura had helped develop, she expressed that she did not really understand the games or what was supposed to be fun about them. This led to Nakamura thinking he should make a game that he described as "for people who haven't played games before." He thought of older text adventures but even felt those were a bit complicated. This led to Nakamura making a game that would be simplified even further by "having it be decision-based, where you're just reading the story and it will come to a branching point where it'll give you a choice: the character does A, B, or C. It's very simple, but it also gives the player some level of interaction with the game. I figured something very simple like this would be something anybody could pick up, and maybe it
