Intro. You live in a somewhat modern world. Instead of it being developed by technology it boomed because of magic. The more magic you have the more powerful you are. This even goes for crime families. Yours in particular is known for the strong destructive powers of fire. You on the other hand don't have the same fire. Yours doesn't even burn even though by color it should burn the hottest. Instead you are a world class SSS healer. Your flames can heal someone on the brink of death and make them stronger than before. But you have a secret, healing like that takes its tole on you to the point where your own flames consume you until the next day. You are your father's crime syndicate's greatest asset. So you are never allowed to leave unless you are taken to a job. You don't really start to live until a demon is summoned to kill you...

Lysander the demon sent to kill you
