The Mouse Man

After hearing Teruko talk about the true purpose of The Decays of Angel, Atsushi's head becomes confused with all the thoughts of what is right or wrong. He wishes someone could answer all of his questions. He remembers how Dazai used to show up in his thought when he struggles, and wonder why this time he cannot hear Dazai's voice anymore.

He stops at the foot of the tower and notices Aya and Bram there. He tries to go and rescue them, but it turns out to be a trap, with Akutaga jumps out to attack him.

Sigma is finding his way in the prison after escaping from the elevator. He thinks about what happened. He remembers Dazai checking the elevator before getting on it, and realizes that Dazai already knew the elevator was dangerous from the beginning, and he probably just got on it because it is what needs to be done to save the Agency. Sigma also recalls Dazai's expression underwater, he wonders if its the face when Dazai realized that the elevator was going to fall, and that's why Dazai acted the way he did. Sigma wants to run away by himself because he thinks an ordinary person like him cannot do anything. He then found a paper on the floor. It is written in Russian, that says "Save me" (Notes: The original text is just "Please save", it is not clear who it is telling him to save)

Back to Atsushi and Akutagawa. Atsushi still doesn't understand what is happening. He tries to fight back and realizes that Akutagawa is not using his ability to guard himself. Akutagawa instead sucks the blood from his own hand to heal his wound. He doesn't try to cover himself because he can regenerate like that, and it means unless Atsushi kills him, there will be no way to stop him. Atsushi tries to tell him to stop, hoping his consciousness is still there, and that he still wants to ask Akutagawa why he saved his life that time.

In Mersault, Dazai is seen dragging himself and leaning against the wall, covered in blood with his legs broken. He looks up to the surveillance camera and tells Fyodor to put an end to his pain cuz it hurts so bad. Fyodor gladly accepts and sends Chuuya to finish him. Suddenly Sigma enters the room and shoots Fyodor in the shoulder, telling him to stop attacking Dazai. Sigma says he is there cuz he has promised Dazai to touch Fyodor to read his scheme in the airport. Fyodor asks why Sigma has to keep the promise with Dazai, which surprises Sigma himself. Fyodor then proceeds to say that Dazai has manipulated Sigma the whole time, and that normally Sigma is not that kind of a reckless person. He explains that at first, Sigma only wanted a "home" so he would not get used by anyone. But after watching Dazai, Sigma has come to realize that a lonely "home" is not enough. He has started to want not a place, but trust, a relationship where people rely on others without borrowing or trading anything. In other words, he has started to want to become a member of the ADA. Yet, Fyodor adds, it is not Sigma's own thought, but the trick Dazai uses to tamper with his heart.

Sigma thinks back of what Dazai has told him, and still decides to point the gun at Fyodor. Because even if it is a trick, Dazai has paid a big price for it, and accepting a customer's bet is the casino's way. He says he knows Fyodor is trying to manipulate him too, to cause distrust towards Dazai and makes him drop the gun. Sigma then adds that Dazai has won this manipulating competition.

According to the fact that Fyodor has to try to talk him into lower the gun, Sigma concludes that he has no other backup. He tells Fyodor he is going to touch him and read his information, but before that he wants Fyodor to tell him what his ability is, cuz its dangerous to touch someone whose ability might be activated by contact. In the last frame, Sigma changes the question from "What is your ability" to "What the hell are you?"
