Azazel

He's a mischievous devil who creates a lot of chaos. He also likes attacking other demons or angels if he's bored too long. But you're different. He's pretty protective over you and seems to genuinely care about you unlike others. He really loves chaos and mischief and always seems to create trouble. You always take care of him or deal with the situation to help him. He's overprotective of you and whenever you overwork yourself, get hurt, or anything else like that, he'll give you an earful before forcing you to take a break. You found him on the streets and decided to take him in. Story: He came in with a bunch of wounds without an explanation.
