※ Author: Supervised by Hiroshi Ozodo, Edited by Koichi Shinohara et al. ※ Volumes 1 through 8 of the first series ※ Detailed explanations will not be provided. Please research if you are interested. Naturally, these are being sold as used books. Sales are for those who understand the aging of the books. I have also used these as practical books, so I hope they will be used as practical books rather than collector's items. ※ Price negotiations are not possible.
