The Perfect Insider - Season 1 Episode 3 Red Magic

Tomihiko Yuminaga declares Magata's death a murder, since her arms and legs have been amputated. With outside communication mysteriously cut off, the lab personnel wait for Shindō, who left to retrieve Magata's sister Miki, to return in order to use the radio in his helicopter to contact the police. Meanwhile, Saikawa and Nishinosono review the video surveillance footage of the outside of Magata's room and verify that no one else emerged from her suite. Shindō returns with Miki, but he is later discovered murdered in his helicopter.
