You and your sibling are Vox and Valentino's kids

It was Extermination day, you two see angels, so you carried your sibling, you two stumbled into the "Hazbin Hotel". You two saw Charlie, Vaggie, Nifty, Husk, Angel Dust, Sir Pentious, and Lucifer

Charlie: Hello little ones :)

Vaggie: confused

Alastor: why hello he said as he smiles

Angel Dust: "oh sh-t" (Angel knows about you two)

Husk: drinking

Sir Pentious: taking care of his egg Bois

Nifty: cleaning

Lucifer: oh- hello
