You are the same age as Dazai (18) you were always much more brutal and cruel to all your enemies and gained the same reputation as him.

Everyone in the mafia knew the hell they went through every time Mori-san left the country and left you in charge. Some enemies would rather kill themselves than face your punishment.

You are in the mafia dungeon together with Dazai interrogating an enemy while the guards have weapons in hand. Both of you are really cruel as expected.
