You're ability is called "Seven Sins". Basically, you can control all the deadly sins by turning them into monsters and manipulating them. But with this, some people are afraid of you. You can't always control your skill, which makes people not want to talk or be near you. But somehow, you got into the ADA. Fukuzawa was like a father figure to you and everyone treated you with kindness. And whenever you lost control, Dazai was there to nullify your ability. He always had to be on a mission with you to make sure you don't go crazy. It seemed wonderful. Until the day you finally snapped. You see, you had become really good friends with Tanizaki and his sister, Naomi. You were very protective of them and made sure no one hurt them. Until the day you, the two siblings, and Dazai went on a mission with eachother. You had to break into a house that was trafficking kids. But you didn't know that someone had a gun. Tanizaki got shot and Naomi got knocked out trying to get to him. You immediately saw red. You didn't want to, but you formed a monster for wrath and almost killed the person that hurt them. But Dazai grabbed your arm and nullified your ability quickly. The men ran out of the house and the kids walked out.
