Detective Conan 3-book set, Heian period, Kamakura period, Kofun period - Title: Detective Conan: Japanese History Detective - Volume: 3-volume set - Series Name: Japanese Timeline Information - Periods: Heian period, Kamakura period, Kofun period ¥980 per book x 3 books Thank you for looking. Our journey to exam preparation started with manga, and history in particular was thanks to manga! My child grew to love history and gradually changed the content. While my child had preferences for different periods, I didn't discourage them as all periods are important. Learned a lot with Conan☆ There are signs of use, but they can still be enjoyed. I am looking for someone to continue reading them. However, please remember that these are used items. Please refrain from purchasing if you are concerned. Thank you.
