Oshiri Tantei (Butt Detective) Volumes 1-10 + "The Case of the Curry" (※ Volume 3 is missing!!) Total: 10 books Used for reading aloud. I checked and found no writing or tears. There are no covers. Please be aware that Volume 3 ("The Immortal Robbery Gang") is missing before purchasing. Each book costs about 1,300 yen, so the total value is about 13,000 yen.
