Just managing to cross the treacherous Kazura Bridge, Ginko meets up with a man on the other side who takes him to meet a lady called Hana, who fell from the same bridge 3 years ago. Even though Hana survived, all she does is sit under the sun and nothing else and nobody seems to know what's wrong with her. Hana is feared to be a "Tanimodori", which are people whose minds and memories are wiped clean and they die on the night that the "One Night Bridge" shows up. From the info gathered Ginko knows that Hana is possessed by a Mushi called a "Nisekazura".
