When Totonou Kuno (Masaki Suda) was thinking of going to an art exhibition to be held in Osaka, which he learned from Inudogaji (Eita Nagayama), a new serial murder case occurred at the Onei police station. I received a request for support. Seiko Furo (Sari Ito), nominated by Nariaki Aoto (Michitaka Tsutsui), heads for the investigation headquarters.The crime, which had already killed three people, is a bizarre case of abandoning her body like a crucifixion in the middle of an intersection. In addition, blood that does not belong to the victim is detected in the wound of the third body. Blood is consistent with the victim killed 22 years ago by DNA testing. It is Tokiko Tsuji, the 17th victim of a series of female assault murders by Gento Hagoku. The investigation headquarters is wondering if Hagaku, who had disappeared since he committed the 18th murder, has begun murdering again. However, the police officer Bizenjima (Eiichiro Funakoshi) says that it was not the crime of Hagoku. His subordinate, Toake Nekota (Wakana Matsumoto), agrees that the situation is different from the case of Hagoku. Furo Hikaru, who was listening to the conversation, was instructed by Bizenjima to form a buddy with Nekota.On the other hand, Iji was chasing a person named Jute in search of the truth about the death of Aiju (Mai Shiraishi). Then she finds out that Aiju frequently went to the warehouse district by her taxi during her lifetime. There, the darkness casino was held irregularly. After infiltrating the casino, I met Rumi Yokota  Natsuko) and was informed that Aiju was working at the casino.At the investigation headquarters, it is highly possible that the body was temporarily folded and carried. Nekota, who was listening to Furo Hikari, reported that a girl walking while pushing a suitcase was witnessed near her abandonment site. At that time, an anonymous person called Bath Hikari with a sauce for the incident.
