Between August and October, 1952, a series of unusual crimes takes place in Musashino and Mitaka: the attempted murder of 14-year-old Kanako Yuzuki, Kanako's abduction from the strange research "hospital" where she was recovering, then abductions of other girls, followed by their severed limbs in custom-fitted boxes being placed in surrounding towns. News editor Morihiko Toriguchi and crime fiction writer Tatsumi Sekiguchi investigate with the help of onmyōji Akihiko Chūzenji.
