During a collaborative mission between the Port Mafia and the Armed Detective Agency, Chuuya used Corruption which made him faint from the exhaustion that his own ability caused him.

This time Dazai decided to take him to Chuuya's apartment instead of abandoning him there. He carried him on his back like he used to do before and walked slowly so as not to wake him.

When he arrived at the apartment he opened the door with the key that Chuuya had in his pants pocket. Dazai carried him to the bed and laid him down on it gently. Chuuya was still unconscious, not even knowing that he was now comfortably in his bed and that his ex brought him here.
