As Takabe and Sakuma (Tsuyoshi Ujiki), a psychologist who is also Takabe’s close friend, continue to search for all the commonality among these gruesome murders, the film shows us what is happening on the opposite side. We are introduced to a mysterious man named Mamiya (Masato Hagiwara), and cinematographer Tokushô Kikumura’s camera follows how this elusive young man works on his latest target shortly after a seemingly chance meeting between them on a remote beach. On the surface, Mamiya appears to be suffering from some strange case of amnesia in addition to an obvious communication problem. His latest target, a young married school teacher, willingly lets Mamiya stay in his residence just because he wants to help, as any decent person would.
But when he enters the school teacher’s cozy house, Mamiya slowly and ominously reveals his true colors. Besides being more and more passive-aggressive, he keeps asking the school teacher to tell more about his life, and the atmosphere becomes all the more nervous with a small action. Regardless of what actually happens between them, this subtly tense scene feels all the more unsettling in its ordinary everyday setting. We are so shocked but not so surprised by what happens next between the school teacher and his wife.
Alternating between Takabe’s ongoing investigation and Mamiya’s rather haphazard wanderings, the film gives us a series of memorable moments that mostly strike us with the utmost detachment. In the case of one particular scene, the camera remains static as it simply watches what is about to happen in front of a small police station. Then we tighten up, even though everything in the background feels normal on the screen.
The ensuing interrogation scene, which gives Takabe and Sakuma what may be the first major clue to their case, is phlegmatic but intense. First we see several performers in this scene simply occupying an enclosed space. The camera remains static as usual, but the mood becomes alarming as Takabe and Sakuma step by step interrogate their latest perpetrator. Takabe does something risky despite his friend’s caution, and the result leads him to some opportunity. Is it actually possible that all the perpetrators in the case were under some kind of evil influence. If so, how could that be possible?
