This is a set of 5 books: Tengoku Daimakyo volumes 1-4 and Gaitenrou (complete in 1 volume). I purchased these at a bookstore and stored them on a bookshelf after reading them once. Tengoku Daimakyo is all first edition, and in very clean condition with no stains, folds, or sun damage. Volumes 2 and 4 include purchaser bonus papers and cards. Gaitenrou has a slight fold on the bottom right of the back cover, but otherwise, there are no noticeable folds, stains, or sun damage.
