____________________________________________________________________
Mya L. Jackson is a 17 year old girl,she's sweet and kind,she loves to cook and dye her hair,and she's always had a thing for adventure. She loves to travel and explore.
She does have school but she only goes when she absolutely has to. She not like other girls,she doesn't care whether a cute boy is looking at her,no she cares about demon hunting. Her parents were Exorcists since the beginning of time. She never had an intrest in it until they were brutally murdered by one of the most dangerous demons in the country. After their murder,she was in the next room getting branded by the same son of a bitch. Now that brand is like a tattoo,big and permanent. It's a black butterfly on her upper left arm. Her nickname is Angel and that's what all demons know her as.....
She has her own brand,it's cute and small. It's a flower in a designed circle - it means safety of angels. She's only branded one person but they weren't really a person,they were a demon; if you brand a demon it's supposed to kill them but he didn't die,he survived - she thought it was due to him being really young,maybe 15 or so but that was 3 years ago. He could be dead for all she knew,she never even knew his name but she's always felt like she should've done something different.

Caleb M. Sanders is an 18 year old boy,he loves to play soccer and go on youtube. He has a best friend named Aaron Damen Carterson who is a year older than him. Caleb loves to eat and be weird. But he's not normal,he's a demon and one of the most important ones in the country. He's killed over 238 humans and only 34 Exorcists. He only killed them when he had too,he made a promise to an Exorcist when he was younger to never kill them unless it was absolutely necessary. He attempted to keep the promise and kind of has. He's been branded twice, once by his father - for good luck and the second time by the girl he made a promise to. He had a black butterfly on his neck and a flower on his hand. His parents kinda ditched him when the girl found him,his mother's exact words were,"I can't see my boy do this,it can't be possible!" He was so confused but they probably thought he was dead right now. He doesn't really know he hasn't seen 'em since he was around 15-16.
Now he lives with Aaron and they both have youtube channels due to boredom. No one knows their secret and never will,Caleb will make sure of that...

What the hell will happen when the demon finds his angel?
