A comic version of "Scary Stories That Happened at School", a masterpiece that decorated the final days of the Super Famicom... ... but although there is an interview with the creator, the content of the game and the manga are not related. In fact, the article on the game is less than 10 pages long, including the interview with the creator... Well, it seems that this book was made before the game was released, so to be honest, it is a horror manga book that is unified with horror manga set in "school". However, since it was made by the world-famous ASCII, there is not even a trace of the cheapness of making it by gathering up some unemployed manga artists. It has a pretty luxurious (in other words, strong) cast, and there is a wide variety, from pure school horror to crazy horror.
