This is a set of all 15 volumes of the compact-sized Kadokawa Manga Learning Series, which allows you to enjoy learning about Japanese history. It seems like I purchased them 7-8 years ago. I've only read them a few times, so I think they are in relatively good condition. - Series Name: Kadokawa Manga Learning Series - Title: Japanese History - Number of Volumes: All 15 volumes - Features: Compact size, easy to carry Thank you for looking.
