Demon Slayer, Complete 23 Volumes - Series: Demon Slayer - Volumes: Complete 23 volumes - Author: Koyoharu Gotouge Thank you for viewing. I purchased this set at Book Off, but I'm selling it because I ended up with two sets due to a mix-up with my family. There are some scratches. Also, as it is still in the bag from when I purchased it at Book Off, I haven't checked the contents, so there may be some dirt inside. There are no smokers or pets. I plan to ship it in a cardboard box after taking waterproof measures.
