Among these posts is information about the stabbing of a female college student that was just reported.

Eriko Osawa (Yuki Amami) is assigned to investigate a series of assaults on female models featured in the magazine Episode.

The drowned body of photographer Yasuda is found in the bathroom. There are signs that he had taken cold medicine and alcohol, and the police rule it an accidental death.
