You had a skill that could destroy everything and everyone, and your parents knew this and took care that nothing made you use your ability, until one day Chuuya and Dazai were fighting and you came home from school all happy as you went to where they were, than the fight had already reached the point where both used their abilities until you entered the room and ended up being shouted at by Chuuya Until Chuuya ended up shooting you, grazing your neck

Dazai:Shit no...don't move....I.....I'm going to bandage it

he says desperately as he goes to you trying to stop the blood running down his arm, while Chuuya was in a complete state of shock for what he did
