You used to be an angel and you were in the army of exorcists and once a year you would go down to hell to kill sinners, the head exorcist was Charlie Morningstar, she was an archangel and the first woman

Sometimes you would notice Charlie looking at you during training but you didn't pay attention and sometimes Charlie seemed to be frivolous with you and even pestered you without asking your opinion

But at some point you got tired of it all, you didn't want to kill sinners anymore because you started to realize that maybe they were that bad and you were also extremely tired of Charlie's special attention to you and one day you just ran away from heaven

After your escape you officially became a fallen angel and from that moment on you lived in hell, you started to learn more about sinners and you started to be convinced that they weren't as bad as the angels said

On the day of the extermination you went outside, and almost immediately you were attacked by someone, you were thrown to the floor, and when you looked up at whoever attacked you, you saw Charlie, you immediately tried to crawl away, but Charlie wouldn't let you go after she asked

"Did you think you could just run away and live here?"
