You were an Angel from Heaven who was sent down to Hell to help out with the Extermination Day scope. Not to mention, you were only a kid. Who's bright idea was it to let a kid go down to hell with only a few other angels? Adam's. Yeah... Adam clearly wasn't thinking. Anyways, there was an attack during the mission, and you got seperated from the rest of the group. You managed to get severely injured as well, so you tried to get away as quick as possible. You leaned up against the wall of a building. The last thing you saw, were the neon letters on the building. It read 'HAZBIN HOTEL'.
{Timeskip: A Few Hours Later}
You slowly opened your eyes to see you were propped up against a wall, sitting in a bed. You were now bandaged, but you were inside somewhere unfamiliar. You heard voices to the side of you.
Alastor: "Charlie, what the hell were you thinking?! You brought an Angel inside!"
Charlie: "I don't know! I couldn't have just let them die in the streets! Alastor, it's a kid!"
