Sasafuna Koyama-young writer who decided to visit his grandparents for a variety. Waiting for his return, he stumbled upon a strange wooden box filled with manuscript called Kakuti. In fact, this is the incomplete work of the former writer Chidori Yukimura, who died of the disease at a young age of 29 years. Kakuti is a hotel located by Amanan, who lives the vital power of its guests, mostly people who are drawn into the world inside the manuscript after reading it. Unfortunately, Sasafun has a rather weak body, so it will not be a very good "food supplier." That is why they decided to let the sassafoon whenever he leads the hotel of another guest.
