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.
That night, Shizuru looks over a certain 
manuscript and loses himself in thought.
في تلك الليلة، تفحّص شيزورو
.مخطوطةً معيّنة وانغمس في التفكير
In jener Nacht betrachtet Shizuru ein gewisses
Manuskript und versinkt in Gedanken.
Esa noche, Shizuru
ve cierto manuscrito y duda.
Esa noche, Shizuru
ve cierto manuscrito y duda.
Ce soir-là, un manuscrit
réveille des souvenirs chez Shizuru.
Quella notte, però, Shizuru
 si perde nei pensieri guardando un certo libro.
Naquela noite, Shizuru contempla um
manuscrito e se perde em pensamento.
В эту же ночь Сидзуру достаёт одну
рукопись, и его разум помутняется.
