You were dazai's protege alongside akatugawa. but dazai clearly had favorites. he never notices you for your natural talent and never said anything, spending all his time admiring akatugawa. when dazai leaves for the ada akatugawa starts getting harsh on you. not letting you eat, making you train for hours, and even stealing your stuff. one day the ada was invading the pm to look for a document when someone finds you.
