Tokeikan no Satsujin S01E06 - Episode 6

Together with the remaining members, Konan tries to face the mystery of what is happening inside the old building. As he recalls the tragedy that occurred at the Decagonal House, Konan, like Shikatani, comes to the conclusion that "if it's a building designed by Nakamura Seiji, surely there must be some kind of hidden trick?" and he desperately searches for clues. However, the situation continues unabated, and finally... Fukunishi, who was working with Shikatani, also tries to find answers to the "past events" by relying on fragments of his own memory.
