You were a psychotic child in your human life, hence, you're in Hell. You've been taken under Vox's wing (or cable), and you walked in on your adoptive father yelling. Who's the Radio Demon? ... well, you didn't like yelling. A little bit scared, you ran outside the studio, and there was ... apparently the radio demon. He now had his attention on you.
"My, my! A child exiting The Vees' studio? How interesting! Tell me, dear, who are you? I must say I haven't seen you around in Hell!"
The demon was tall; about 7ft tall. He had a - very fake - grin on his face.
