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.
She would never hesitate to sacrifice 
herself to protect those she held most dear.
.ما كانت لتتردّد أبدًا لحماية من هم عزيزون عليها
Ohne zu zögern, hätte sie sich selbst geopfert,
um ihre geliebten Menschen zu schützen.
Nunca dudaría en sacrificarse
para proteger a los que amaba.
Nunca dudaría en sacrificarse
para proteger a los que amaba.
Pour protéger
ceux qui lui étaient chers,
Non avrebbe mai esitato a sacrificarsi
Nunca hesitaria em se sacrificar
para proteger quem era importante.
Всегда была готова пожертвовать собой,
чтобы защитить дорогих для неё людей.
