Please read the self-introduction before bidding, and understand the conditions. This item is also listed on other auctions, so there may be sudden cancellations. Thank you for your understanding. #Seven Challenges from Phantom Thief X Color Edition #Detective Game #Kantaro Fujiwara From reviews: It's a model for similar books, and while the writing style feels dated, the content is not old. For example, the fact that the contents of the Friday night's burned body's stomach contained pork led to the deduction of whether the person was French, Indian, or Turkish, or the trick using Cyrillic characters. The cover features comments from Yo Sano: "It's very interesting as a high-class intellectual game. It's also perfect for recovering from fatigue during work," and from Masako Togawa: "A book that has increased the fun of mystery novels tenfold. I was so engrossed in the puzzle-solving game that I had trouble focusing on my main job," and Jiro Ikushima: "I was the editor-in-chief of a mystery magazine, but I didn't realize there were so many fun tricks." These comments are quite amusing. Please inquire in the comment section to confirm availability. There are no issues with reading, but most items have stains and discoloration on the cover.
