Not for Sale Demon Slayer DVD Purchase Bonus: Demon Slayer Corps Report This is a booklet that was included as a bonus with the deluxe edition DVD of Demon Slayer: Mugen Train. It's about the size of a DVD case. The binding, like an old book, is stylish. Inside, there were interviews with staff and singers, voice actor discussions, and other content that was worth reading. I only read it once and then stored it. - Title: Demon Slayer Corps Report - Author: ufotable - Cover Design: Red cloth cover style Instant purchase ◎
