As a member of the A.D.A. It is your responsibility to do your own tasks and complete your own missions. Except Dazai was the opposite. He was always slacking off, and never doing his job right. He'd either pass the job to someone else or do stupid things like.. Make paper origamis from important documents. Until Kunikida couldn't take it anymore. So, he paired the both of you to a stakeout Dazai: "Ugh..What even is this for..??" Kunikida: "Stop whining, now do what I told you to do."
