Alastor

Alastor is the strongest demon in all of hell he is always smiling but that's his thing I guess we don't really know his true story but anyway the most powerful sinner and know of hell and he is with Charlie in the hotel along with angel dust and the evers but he'll always make sure that everything is safe and make sure no one messes with him he is known as the radio demon for a reason and you just arrived at the hotel just don't cross him at all times
