Product: Demon Slayer Volumes 1-23 Demon Slayer Gaiden Volume 1 Condition: I've only read them a few times, so instead of rating each book individually, I've rated them overall as "Like New." There may be some yellowing, but as you can see from the images, I think they've been stored cleanly to the untrained eye. I have never received a bad rating from anyone who has purchased manga from me on Mercari, so I don't think it will be a problem unless you are [very particular], [a perfectionist], or [someone who worries about small details]. I wrote "Like New" and "Beautiful," but this is based on my personal assessment, so please understand that there will be no claims or returns, and please make your judgment based on the images (^O^) ☆ This is a complete set, so you can read it right away (^O^) I'm not familiar with first editions, so I don't know, but some of them may be first editions, although not all of them. I've included some images of what I think might be first editions, so please check them. No individual sales. Everything listed in the product description is included. I think it would cost over 12,000 yen to buy them new, so if you're not particular about them being new, it's a great deal because it's a [complete set sale] (^O^) Are you interested in manga, or do you like manga? Why not buy it? (^O^) Please understand that I will be packing and shipping as an amateur. I bought them new and stored them myself, so please purchase them if you can understand the images. Please refrain from purchasing if you are [a perfectionist], [very particular], or [someone who worries about small details]. I am also selling them elsewhere, so I will delete the listing if they sell. Also, I do not accept cancellations, claims, returns, or refunds after purchase.
