After receiving a suspicious phone call from an unknown caller, Himura and Arisugawa find a body at a condominium. With the scent of perfume lingering, they deduce that someone was there until just before their arrival.
Given that all three murder cases which occurred around Akemi must be connected, and hoping to find more clues, Himura and Arisugawa go to where the second murder took place.
Two members of Shangri-La, a radical group, are murdered in Tokyo and two teenagers are murdered in Kyoto. Rumor has it that a high schooler, Sakamata, aka Apollon is the perpetrator. The photos of four different crime scenes portray something significant.
Arisugawa is taken hostage by Shangri-La so Moroboshi can lure Himura to Arisugawa's location.
