Called in to investigate the whereabouts of Yura, the blind woman he'd fallen in love with seven years earlier, Takashiro Shugo is surprised when even her own father tells him it's hopeless. Takashiro travels to crime-ridden Ueno, where Yura may have recently been spotted, and gets a room in a brothel where the busty red-haired madam owes him a favor. As the case unfolds, Takashiro's memories of his first sexual explorations with Yura are vividly brought back as he finds himself seduced by the hot courtesans at the brothel. Could Yura's longtime disappearance somehow be linked to the grisly crimes gripping Ueno now?
