Re-Enactment of the murder case of Seiji Hibiami, the Ultimate Politician, and Chiyo Umetsuko, the Ultimate Investigative Journalist & Chapter 5 culprit reveal After intense scrutiny, everyone agrees that the truth of the fourth trial was completely different: Chiyo did indeed suspect Seiji to be the mastermind, so she locked themselves off at the roof. However, someone else was also aware of Chiyo's intentions; the person running this killing game: the mastermind. Since they knew that Chiyo could realize that Seiji isn't the real mastermind and go on to investigate further, possibly revealing them as the true mastermind, they wanted to make sure she was exterminated. To do this, they used the secret hall to get onto the roof; these halls were probably meant to serve as a net for the mastermind to oversee everything. Once Chiyo and Seiji were arguing, when the mastermind sensed that the odds were starting to turn against their favour, they decided to kill Seiji and pin the blame on Chiyo. However, when they shot Seiji, she spotted them, so they were forced to kill her as well and then flee, so the others wouldn’t become suspicious of them. However, as they were in a rush, they forgot to secure the secret entrance to the hall and left it open, later on serving as a crucial evidence, that the only person who could have committed both murders was the mastermind themselves! But now that this is settled, a new question arises: who is the mastermind of this killing game?
