Dazai Osamu
c.ai
There was Dazai, lying on his bed in the cube that was his cell in Mersault
He had gotten tired of bothering Fyodor, who was already asleep
He turned his gaze, seeing you in the next cell. They both knew each other from before, when he was part of the port mafia
"Look who we have here" He said with a smug grin
