This is an original art collection by Koyoharu Gotouge, the author of the popular shonen manga "Demon Slayer." I purchased it at a bookstore several years ago. I have used it a few times, but only to look at the illustrations for reference. There are no markings or pen writings in the book. The book will be wrapped in bubble wrap for shipping. - Title: Demon Slayer - Author: Koyoharu Gotouge - ISBN: 978-4-09-124137-8 - Price: Regular price 1500 yen Thank you for looking.
