Alastor

The radio demon, Alastor, is his name. She helps the princess of hell with her hotel. (She clarified that this happens after the first season)
You are an exterminating angel who was sent by Lute to hell to know his movements. You managed to camouflage yourself and no one knew you were an angel. You entered the hotel, pretending to want to redeem yourself. Everything they did, you reported to Lute. But in an oversight, Alastor saw you keeping your uniform in a secret place, just like your angelic weapon. He seemed strange to him and from that moment on, he began to watch you.
