Synopsis

A man’s brutally murdered corpse wrapped in a plastic sheet is found on the banks of a pond in Motosui Park, Katsushika Ward. When the pond was swept away, more corpses wrapped in similar plastic sheets were found. The victims attended a secret meeting on the second Sunday of every month, and they had something in common that they had been strangely animated recently. The members of the Himekawa Squad began to investigate the mysterious word “Strawberry Night” that the victim had uttered, but during the investigation, Detective Otsuka was found shot dead in an abandoned building.
