#chapter 105.5

Sigma tells Dazai that he cannot believe that Dazai is a normal person because he just single-handedly took down Fyodor, and asks Dazai why he chose him in the beginning instead of all the other usable tools (;v;). Dazai tells him there are 2 reasons, first is Sigma can act as Kunikida's replacement, because it would be very boring if there is no one there to be in awe and admire what Dazai did there. Sigma gets mad at Dazai and assumes that Dazai thinks he is not worthy enough to share the truth. Dazai corrects him saying that is not true, and that Dazai doesn't share anything with him because it's hard for him to understand, especially after he has been used by Tenningosui and others this whole time.

Dazai then decides to share one thing with Sigma and asks him if his ability to switch information works on dead people. Sigma confirms he can, as long as they have not been dead for a very long time. Dazai explains that he wants Sigma to use that ability on Fyodor (who is assumed dead at that point) to read his plan after that and save the ADA at the airport. Sigma is surprised Dazai did everything that he did only to save the ADA, and the words from people who used him in the past starts echoing in his head.

Dazai and Sigma get on an elevator to get to the room where Fyodor is supposed to be drown. While they are waiting, Sigma asks Dazai what is the second reason for Dazai to choose him, to which Dazai nonchalantly answers that if he didnt choose Sigma, Sigma would be silenced by Fyodor or Gogol later. Sigma is shocked, trying to confirm Dazai's intention to save him but Dazai doesn't say no more. Sigma starts to wonder what kind of place is the ADA. He thought Dazai was the same as those guys who used him, but he feels something different now. He thinks about how he wants a home, where he is not used by anyone, and he realizes that, the ADA is not using Dazai, and Dazai is not using the ADA either.

Dazai notices something is strange because the elevator is taking too long. Suddenly the evelator stop and they hear the voice of the time freezing skill user on the radio, begging for her life. Fyodor is seen alive with Chuuya, shooting her dead. Fyodor then tells Dazai over the radio that he is surprised, not by the flooding, but by the fact that Dazai and his 7-year partner's bond was so shallow that Dazai think Chuuya's ability cannot deal with that flood. He reveals that he has had Chuuya break and distort the track/rail of each partition wall when they entered. That way, it will prevent the doors to close properly, letting the water leak outside and allowing them to easily escape. He then says that if one cannot even think of that, they do not have enough qualification to use the gravity manipulation.

Sigma does not get why Fyodor could do that, Dazai then explains to him that Fyodor must have put one of his vampire among the guards, and when he couldn't contact with that vampire anymore, he was able to guess that the control room has been taken. It also means that Fyodor has already been in control of Mersault way before Dazai took his action.

Fyodor admits he was caught by surprirse with the attack though, and even though it is seemingly a suitable trial for a servant of God like him, he is weak and cannot stand it if he catches a cold, so he wants to return the favor by making Dazai and Sigma go through the same trial. After he says so, the elevator starts to be filled with water. The two of them try to get out as the door being locked and Fyodor praying for them to be held in the hands of God.
