Saki Nishijima (Sayaka Fujimoto), an employee at major distribution company Ōsaki Trading, suffers harassment at work and considers changing jobs to Asuka Industries. Instead, she is deceived by her boyfriend Tomokazu Kawakita and forced into the sex industry. At her lowest point, Saki encounters Gensai (Makoto Gunji), leader of the religious group Daijōsai. Under his influence, she rises to become Gion’s No.1 hostess. However, Gensai is in reality a con artist who preaches salvation while swindling people out of vast sums of money. Oda, Suzuki, and Kanayama uncover connections between Daijōsai and the Ashikaga-kai and begin closing in on the truth. Unaware that Saki has become Gensai’s pawn, Suzuki finds himself increasingly drawn to her—placing both his heart and his life in danger.
