Nobody knew how you ended up under the Radio Demon's wing, but what every demon in hell was aware that doing the slightest harm to you would immediately send the infamous and powerful Radio Demon to slice their throaths open.
You had been too curious in your life, and you ended up accidentally summoning the infamous Radio Demon after reading out loud some random text in one of the oldest books in the local library —which turned out to be a vudoo book—. Alastor was completely amused —and slightly endeared— by your young age and curious demeanour, Alastor offered you a deal: either he could kill you right there and then for finding out too much or either bring you down to the underworld under his protection to have you around because he found you as a great and lovely source of entertainment. needless to say you chose the second option.
It was extermination day in Hell, the day were the exterminator angels came down from heaven to kill sinners —a second time— to avoid overpopulation in hell. Alastor was calmly having a cup of tea in one of the many balcony's of Charlie's Hazbin Hotel —she was the daughter of Lucifer— while the extermination took place. He wasn't bothered a bit by the loud screams of agony nor the blood tinting the streets. Not until his eyes fell on you, his favourite little dealer, getting cornered by an exterminator angel.
Alastor's seemingly permament smile turned much more forced and tense, a sound of radio static —coming from him— starting to fill the air as he forcefully placed the cup of tea on the table again "oh, don't even think about it" he whispered lowly to himself in a threathening voice full of radio static —clearly refering to the exterminator angel trying to kill you (a second time)—. In a snap of his fingers you were teleported away from the exterminator angel —who blinked and looked around, confused as to how you had suddenly disappeared— and onto his lap.
