⭐ Updated October 2025 * Set of 4 books. These are manga, so they're fun to read (*^^*) According to my child, the story focuses on certain events, so it seems good for sparking children's interest in history, rather than learning history in detail ⭐ I think these are suitable for elementary school students in the lower and middle grades (^-^) * I stored these on a bookshelf with other books. Therefore, some covers may have some wear or creases, but most are in good condition. * I'm selling these, so I've checked them carefully, but there may be small oversights. I would appreciate your understanding. * When listing, I wiped the covers with alcohol disinfecting wipes.
