Yuube wa Otanoshimi Deshita ne (It Was Fun Last Night) by Renjuro Kindaichi This is a set of volumes 1-11. I bought some of them used, and volumes 7 and later were new. No rental copies. Volume 6 has some soiling on the edges, and volume 8 has a slight bend at the bottom of the cover, so the price is reduced. Thank you.
