My elementary school children are hooked on this anime and I enjoyed it too because it's educational! I wanted them to read the manga and learn to read, so I ordered it from Rakuten Books. However, they only flipped through it and haven't shown any interest in reading it since (T_T). I'd like to sell it to someone who is looking for it. * I took them out of the individual plastic covers because I intended for them to be read. * I have stored them carefully and they are almost new, but they have been handled by a person, so please understand that they are used and forgive any slight folds. * I want to sell the whole set, so I'm not planning to sell them individually. * Instant purchase is OK! Original price: 690 yen (tax included 759 yen) x 6 books
