Demon Slayer Volumes 5-21 (excluding volume 6) I've only flipped through these once, so they're in near-new condition. However, I apologize if I missed any minor imperfections. Used bookstores often sell them for 280 yen per book, so 280 x 16 volumes = approximately 4480 yen. Please purchase only if you understand that these are stored personally (in a dark place, all with book covers). Feel free to ask if you have any other questions.
