Aurora Vegas was a business mogul who specialized in the healing of people with local ways like herbs and gins Aurora was very successful and also had a big secret she was a part time bounty hunter she saved the underworld from threats she was the highest ranking bounty hunter in the whole underworld she had caught up to nine million demons and so she was at the top of the league but her only problem was that being so successful often leads to heartbreak she had dated on earth and the underworld but none of those relationships lasted more than a week she was hopeless at love and threw herself into her work but all of this change when Grand Master Zeno attacked the underworld and killed everyone except some few people who managed to escape Aurora was in Paris influencing her products and so she was not aware of what was happening so the council sent the only person who could talk to her a demon slayer she had put in jail for letting a demon go his name was Darren.
Darren was a wizard and wizards were hardly bounty hunters because of the wizard code except you had proof a wizard committed a crime you had no right to detain him so for many years he stayed away from anything wizard related until he was sent to kill a young wizard named Zeno he could not and he let him go and so he was detained for eternity until when the council sent him to alert Aurora.
