This is a set of all volumes (21 books) of Assassination Classroom, plus the official character book (Meibo no Jikan), for a total of 22 books. Overall, there is some yellowing and wear, but I believe it does not affect readability. Please refrain from purchasing if you are sensitive to this or are looking for a perfect item. Immediate purchase is possible. - Please refer to the photos for the overall condition of the yellowing, etc. - Volumes 6, 12, and 19 have folded covers (see photos). - I am a private seller, so I may have overlooked something as I have not checked every detail. - Recycled materials may be used for packaging. - The case shown in the photos is not included. - Volumes: Set of volumes 1-21 + official character book - Author: Yusei Matsui
