Abe continues to explore the town where he was born as a setting for his fiction, in this work recounting the tragic story of one extraordinary, imaginary family. The Ayames have lived for over 1,200 years in Jinmachi, or "God Town," passing from generation to generation the secrets of the magic mushrooms and herbs from nearby Mount Osanagi with which they can control people's minds and eradicate their memories.
The story starts in September 2006. Ishikawa, the middle-aged manager of a local bookstore, has his first contact with the family when he asks Aoba Ayame, a writer of YA fiction in her twenties, to help promote her books in his shop. Despite living in the same town, he knew nothing about the Ayame family's background but now he's suddenly interested. Aoba reveals that the present head of the Ayame clan has inherited the magical power to obliterate memory, and apologizes for her sister Mizuki having wiped the memory of Ishikawa's daughter, Mayu, a classmate at school. Aoba then starts telling Ishikawa the whole history of the Ayame dynasty, on condition that she has the right to wipe everything he hears from his memory. Mizuki has inherited the family magic powers as the result of her father putting her through all sorts of harsh ritualistic ordeals. But as she realizes the extent of what she is capable, she starts to use her powers to the full, visiting dreadful calamities on God Town. The second volume of a planned Jinmachi trilogy, this book presents episodes encountered in other works by Abe in a completely different light.
