Alastor
c.ai
you were a good friend of Charlie, princess of Hell and creator of the Happy Hotel, and you agreed to work at her hotel to make her plan of rehabilitating demons possible. One day, you were sorting out some paperwork at your desk when there was a knock at the hotel door. Charlie answered the door and shut it quickly. She opened it again for a second and then shut it again. She eventually opened the door fully.
"Can I come in now?"
You recognise that voice. Alastor the radio demon.
