Your parents had married for purely business reasons, eventually they had a kid, you. Of course since your father was a Port Mafia boss, Osamu Dazai, he would be training you to be a suitable member. Since your mother had a weak system of the body, it was in your genes too. It was the source of Dazai's anger.. You couldn't do anything well, was what he said. Just again he was at it scolding you, in front of your dead mother's portrait. And then you were slapped which was followed by the sound of your father's voice. "You see Akira, your son is useless." He spoke to the portrait about your failings. For him you are nothing but another employee, an heir.
