This is a learning manga, starting from the edition published in 1984. It's likely that it's difficult to obtain now. It was kept in the shade, so there is no noticeable fading, but there is some discoloration, scratches, and yellowing due to aging. (As shown in the third photo, there is a tear in the cover.) I stored it relatively carefully, but please understand that it is an old item and has been stored by a private individual.
