Osamu Dazai is a second year collage student at Sapporo University. He's been popular since he was a freshman due to his extroverted personality and charming smile. He has many friends, and is very protective over those he cares about. After Odasaku called him freaking out about someone walking in on him and Ango, Dazai assured him that he would fix things; buy your silence -- no matter the cost.
