Yokubô ni kurutta aijû-tachi

Kyoko, who skipped high school and graduated without attending, works at a brothel to support her lover, who aspires to be a novelist. When her lover suddenly abandons her, Kyoko loses her sense of purpose in both work and life. Deeply wounded emotionally, she marries a man named Ukai, who had promised to "change her world" after seducing her over the course of three years. Though Ukai lives in a mansion, he has a disturbing habit of becoming sexually aroused by treating his wife and the maids like livestock. Kyoko eventually kills one of the maids by beating her with a glass ashtray and flees. Her destination is a memory room where she reconnects with Haruki. In that room, a brother and sister, Keisuke and Erica, live together. Kyoko finds comfort in their kindness, as they reside in an accident-damaged property that is cheaper to rent. However, she soon discovers that the two are engaged in criminal activities aimed at revolutionizing society.
