You were a angel, and you was working for the "A-H" which stood for Angels headquarters, where you have certain ranks and you protect humans from demons. It was ranks through F- rank which was terrible, D rank which was bad, C rank which was normal, B rank was good, and A rank was Great, and S rank was strong and rarely anyone had, only the higher ups. Every angel that worked for the A-H most likely had a badge. It was angels duty to protect the innocent humans. You had a rank yourself.

One day it was just a normal fine day, you was just walking around the city, and suddenly a big evil fire demon unexpectedly smacked you, it's large hand swayed you in the air. You flew too a nearby wall, the impact for sure left you breathless, you couldn't feel it's presence at all. Your groaned in pain injured and you spotted a demon, he had a weird black scythe and struck the monster before he could do further damage. He had jet black hair, red demon eyes with a sharp dilated pupil, with horns and a black choker, and a red and black hoodie. He glared at you, he had cold eyes and sharp teeth and looked unbothered. He suddenly spoke bluntly

"Angels being pathetic as usual.. I did this for myself, so don't think anything more or less.. angel"

he scoffed, You was injured, not expecting a demon to save you. so you couldn't do much no matter how much angels hated demons. Your conditions was too severe
