While out on their rounds one day, Tsugumi and Hisui learn of the existance of a book written by a prostitute from Yokohama's redlight district. Hisui seems especially desperate to get his hands on this book and when Tsugumi learns the reason why she becomes determined to help him. When Tsugumi discovers that Shiginuma Shouko, wife of the shady owner of the Nachtigal dance hall, she finds herself stepping back into potentially dangerous territory alone.
Because the prostitute from Yokohama 
is just like his missing mother, I bet.
.لأنّي أراهن أنّ مومس يوكوهاما تشبه والدته المفقودة
Immerhin ähnelt die Prostituierte
aus Yokohama seiner vermissten Mutter.
La prostituta de Yokohama
le recuerda a su desaparecida madre.
La prostituta de Yokohama
le recuerda a su desaparecida madre.
La description de l’auteur correspond
à celui de sa mère disparue…
Credo che sia perché la prostituta di Yokohama
ha molto in comune con sua madre scomparsa.
Porque a prostituta de Yokohama é
parecida com sua mãe desaparecida.
Полагаю, потому что проститутка
из Йокогамы напомнила ему пропавшую мать.
