Sei learns of the fact that Yoshikazu Miyoshi (Asami Mizukawa) was once killed by a stalker at a mountain lodge where a mystery party was invited by Haruo Tenda (Kosuke Suzuki). Not only Kiwa, but the stalker is also dead from the toxic smoke of oleander in the fireplace. Before coming to the mountain lodge, Sei said, 'There is only one person who lie to the participants, so please take a look.' Talk about what you were asked to do. Then, Furo Hikaru was told by the heavens, 'I want you to see someone who doesn't lie.' Sei and Bath Hikaru begin to wonder if there is something wrong with Kiwa's case.The next morning, the awakened participants shovel the snow. When Sei asked Tenda about Kiwa's case, Tenda replied that although there was no evidence of a third party's invasion, he had always felt uncomfortable about the case. And Tenda asks Sei, 'I just want you to see the situation of the meeting without prejudice.' At that time, Furo Hikaru noticed that several branches of Oleander were broken.After shoveling the snow, when Sei and Furo Hikari are cleaning up the tools in the garage, a power outage occurs and the electric shutter does not open and is trapped. Sei takes out a flashlight from the tent that Takakatsu Tachibana (Kuranosuke Sasaki) put up in the garage. Sei and others are released by having the heavens open the door leading to the mountain lodge. The cause of the power outage was that the power line was cut off by the weight of the snow. Restoration will take until the evening, so I will eat lunch for the time being, and Sei will be asked to make curry. I noticed that there was something about the arrangement of observing the participants.
