I've been looking for a manga about books for a while, but I prefer slice of life style stories to action or supernatural manga, so I couldn't find one. I happened across this title in an issue of OtakuUSA magazine and decided to order a copy and give it a try. The premise is about a used bookstore that specializes in manga. Various people come to the store for different reasons, be it to buy a manga or to sell their old volumes. The characters find a manga that ends up changing their life, in some way or the other, but each chapter is presented in a different way, meaning that it isn't always just 'character A has problem, character A finds manga, character A changes forever'. It varies around, which is nice. Being someone who really enjoys nostalgia and learning about the history of manga, as well as someone who can get emotionally connected to something (including manga) pretty easily, this ended up being nearly perfect for me. My issue with it is that the chapters are fairly short, and similar to oneshots. I like that sort of style, but it does make me wonder about what happened to some particular characters that I ended up caring about. What I really appreciate about this manga is the history lessons about manga. There's a lot of old school manga that I don't know about, so I appreciate learning about it. The manga mentioned in the pages of Kingyo Used Books are real, and not simply parodies of said manga. At the end of the volume, a kind of encyclopedic entry of each central manga from each chapter is highlighted. I would recommend this manga to people who are interested in learning more about manga, who already have a solid respect/love for manga. This probably would not be the best choice for children, who may be looking for more action, and not a slice of life style manga. It also wouldn't be the best idea for someone new to manga who hasn't built the appreciation for the range found within it, yet.
