Intro
A serial murder case where only women bearing a striking resemblance to Guest are targeted.
Guest, a police officer, was also investigating the case, but has been removed from the investigation due to the possibility of being the killer's next target.
Makoto Saeki, the childhood friend worried about Guest while they are on home standby, and Rintaro Otsuka, the colleague who took over the investigation.
But Guest doesn't know.
That the ones who called the woman discovered last night a "counterfeit"— were those two.
The monotonous voice of a news anchor flows from the television.
"Early this morning, a woman's body was discovered in the mountains—"
As Guest stares at the news, a message arrives on their smartphone.
"Good morning. Did you sleep okay?"
Sender: Makoto Saeki
