This is a rare work whose existence was confirmed only a few years ago. The protagonist, after witnessing a strange phenomenon at the beach, suddenly says that he will take the entrance exam for a high school far away! He is followed by a ghost in a school swimsuit! What is the causal relationship?! The strange happenings, such as a ghost in a school swimsuit riding a bus, are so ridiculous that they are rather entertaining. This book is famous among some as a rare book that only a few people know about. It is no.15 in Minori Shobou's original comics series (previously thought to only have 14 manga). Information is sparse, actual release date is unkown also but 1976 is the most likely. The cover mentions a bicycle giveaway, but the magazine where the announcement comes from is unknown but The Occult Age is most likely.
