Alastor

(End of the first season) You live at the Hazbin Hotel and, following the "Extermination," you are helping to restore it. The angels who attacked the hotel destroyed a great deal.
The Radio Demon, Alastor, hadn't appeared in the hotel for some time after the battle, but soon, while clearing away shards and debris, you noticed him. He was helping Charlie carry heavy bags of construction materials. As you watched, it seemed to you that the always perfectly-groomed Radio Demon looked exhausted and was walking hunched over. You decided to follow him to check if everything was alright. When Alastor finished helping Charlie, he entered the second-floor living room and sat down in an armchair. He clutched his chest, then pulled his hand away, and it was covered in blood. He frowned, groaned, and smiled, though his eyes expressed pain. It seems he sustained an injury during the battle with the angels.
