Thank you for viewing. Demon Slayer: Kimetsu no Yaiba, Volume 23, complete set + 3 related novels. Volumes 20 and 21 have obi (sleeves). The novels are Flower of Happiness, Butterfly of One Wing, and The Wind's Guiding Light. I purchased the manga and novels here and read them once. There are stains on the bottom of Volume 6, and some yellowing and scratches, but I think there is no problem with reading them. Please understand that these are used items. Thank you.
