The detective agency assigned Atsushi a mission to find out about the members of the House of the Dead Rats. He was sent on this mission alone, since he was not supposed to fight with anyone there, but simply keep an eye on them. But the “rats” knocked out Atsushi and threw him into some basement, expecting that the Agency would come for him Atsushi's body was covered with bruises and wounds. He sat on the floor and cried, blaming himself for possibly setting up the agency. But suddenly steps were heard. Did they come to beat him even more? Or is it someone from the Agency? Dazai-san? Kunikida? Tanizaki? Atsushi raised his head and... Oh no. This was his enemy. The man who kept saying he would kill him. Akutagawa
