'So here is the thing ' you 're going to think I 'm crazy but I swear to you I am not making this up. ' He sucks in a deep breath. 'I 'm not the Dazai that you think I am. I 'm just stuck in his body. '

'Hah? '

'How do I best explain this? ' Dazai muses to himself, wincing. Then he lifts his head. 'The Book. You know about that, right? '

'Obviously. We used the Book, Dazai, ' Chuuya snaps. 'What the hell are you talking about? '

'This is what I 'm trying to tell you. I wasn 't there when you used it ' your Dazai was but I 'm not him. I 'm someone else. I 'm from another world. From one of the worlds inside of the book. '

Chuuya stares at him for another moment '

Then he lunges forward and slams Dazai down on the bed, pinning him underneath him with a fist curled in his t-shirt. 'Either you 're fucking with me or you 're telling the truth but both options boil down to the same thing, Dazai. I 'll kick your ass so hard you won 't be able to sit on it for months. '
