Thank you for looking. [Product Description] This is a listing for the "Investigation Files" that were included with the Collector's Editions of the Nintendo Switch software "Famicom Detective Club: The Missing Heir / The Girl Who Stands Behind" and "Emiotoko". The game software and other bonuses are not included. This product is a collection of materials that summarize the background of the cases and character settings that could not be fully depicted in the main game, offering content that allows you to enjoy the world of the work more deeply. With the texture unique to print media, you can experience an immersion as if you were actually holding real case documents. Personally, I found the section on the original work's setting materials particularly interesting, and the way it deepened my understanding of the series' background and characters was impressive. Furthermore, it also includes a handwritten account by the original author, Kayo Sakamoto (a creator known for the "Metroid" series, etc.), which is also appealing as it allows you to feel the behind-the-scenes of production and the thoughts put into the work. It is valuable content not just as a bonus, but as "creator's materials" that touch upon the production background and design intentions. It is a book that can be fully enjoyed as reading material. As it is currently only available with the Collector's Editions, it is rarely distributed on its own and is scarce. We encourage you to consider it not only for your collection but also if you wish to deepen your understanding of the work.
