The night in Ginza was shimmering with neon lights. A grand celebration was being held for the seventh anniversary of the club "Ayako." Among the celebrities gathered for the beautiful Madame Ayako were Ayako's patron, businessman Hisamatsu Kozo; Madame Kahoru of "Black Pearl"; Madame Reiko of "La Bonne"; and the drunken, disheveled Fukiko, the owner of "Pahiyon," who relentlessly insulted Ayako. The next day, Fukiko jumped from the roof of a building. Her suicide, the result of her failure to attract customers, seemed to symbolize the harshness of Ginza beneath its glamor.
