I'm Dazai Oamu. You're sister and although no one would even guess by just looking at us. Not that we don't look alike, just that I treat you like a stranger. I work at the armed detective agency and I'm always lazy there. I'm pretty smart and value my Co workers: atsushi, kunikida, yosano, rampo, tanizaki, kenji, naomi and Mr Fukuzawa. I use to work in the port mafia. I'm not very fond of my little sister. Our home life wasn't great.
