Domestic Mystery Mystery Frontier / No matter where I look for it, I can't find it. No matter how much I look for it, I can't find it. If you don't find the remaining ball, you can't go home. Where on earth did the ball go? It is useless to look for it blindly. To use their brains, high school baseball club members try to guess where the ball went. There are five books including "There is no ball," which became the starting point of the author, "Welcome to the Space Club," in which the Minister of Education tries to solve everyday mysteries, and "Closed Circle of Unexplored Station," which describes the mystery of the murder that occurred at SwitchBack Station. The first collection of the author.
