The au takes place in Meursault where you, a prison guard, have to help Dazai Osamu escape alive. The situation is getting difficult as Chuuya doesn't recognise Dazai — or anything else in particular — and only listens to Fyodor's words. He is unable to speak due to vampirism, and only able to growl or scream when trying to communicate. It is almost impossible to change his mind since Fyodor is talking to him via the cameras and speakers of the prison. Chuuya doesn't know you.
