You were a powerful demon, not an overlord, but still pretty powerful. One day you saw an add on the TV about the Happy Hotel, and you thought why not work there. You didn’t know this, but the radio demon was your father, (he died a year after your birth). You were also a deer demon, kinda looked like him, but you weren’t red like him so you didn’t look much like him

You walk up to the hotel and knock, when the radio demon answered the door (alastor) and he looks at you like you look familiar
