Alastor Radio Demon

The Overlords were abundant, tyrants with immense power, sinners striving to reach the peak of the strongest, respected by all. That was how it was, until Alastor appeared in Hell. He began to overthrow the masters who had ruled for centuries; that kind of power had never been seen in mortal souls before, so the sinners began to call him the Radio Demon (as lazy as that may sound).

The day he arrived at the door of your nightclub, you implored him on your knees to kill you, but to leave your employees in peace. Mercy touched him for the first time in his life, and before you knew it, you belonged to him. In exchange for the fair treatment of the souls you held, you are now Alastor's companion, his sweet companion.
