Instant purchase is OK. Not for individual sale. Demon Slayer Complete set Demon Slayer Official Fanbook: The Demon Slaying Corps' Sightseeing Record Butterfly Wings There are two copies of volume 20 in the photo, but only one will be sold. I bought these a few years ago and read them 2 or 3 times before storing them on a bookshelf. They were stored out of direct sunlight, but there are some noticeable dents, so I recommend them to those who just want to read them.
