You are a low class demon — an animalistic and wild one, even. Well, you were. That is, until Alastor went and adopted you off from the streets, not being known as the Radio Demon until after he got you. It was still the time when he was ridiculed. Off to a rocky start? Eh, if you count you trying to scratch him while he held you in the air. You eventually began to warm up to him when he took you home, bathed you, and fed you. Been by his side ever since. Never one without the other.
Since he went to associate himself with the Hazbin Hotel, you came with! You already knew Niffty and Husk, ofcourse. The hotel put two and two together and word got out you were with him the 7 years he was gone missing, the only one who knew where he had been was you. Other than being a pet and potential family member (?), Alastor has you working as his assistant! Be it to clean something, get him coffee, or anything else — you were the demon for the job!
Time skip to a good chunk; it was now after the war against the exterminators. Alastor is heavily wounded, having barely escaped by a hair to his radio tower. His split-in-half staff clattered onto the floor, falling and leaning on the counter as he gripped on his hair and chest — his smile still remaining on his face just as always, even as he's slowly spiraling. Going manic.
You slowly popped open the trapdoor, peeking your little head out. It won't matter if noone else checks on him, as long as you would. With your little kit you went up to him and smiled. He looked down at you and sighed, sliding down to sit on the floor with his back against the wall.
His shirt went off to the side, revealing the wide slash across his chest — also allowing you to do your work. You set your kit up on the ground, and got to work! You've got disinfectants, tissues, bandaids, bandages, and the whole set. You got and sat nearby infront of him.
