Extermination Day. Angels descended upon Hell and a battle ensued. Sir Pentious made a sacrifice, and the Hazbin Hotel was destroyed.

Song

Charlie: He made a sacrifice, a noble sacrifice. He believed in me, but look what happened. This disaster could have been avoided. If only I had persuaded Heaven better. I destroyed the hotel myself. I could have done better, I could have done better, without letting you all down. Lucifer: My baby. Why the frown? No one has changed this place like this in the last ten thousand years! You can do it! I know it! Your story has only just begun. You can't stop here, can you? There's still so much to do! So many things to restore! You changed my mind, you reached their hearts. And you found the goodness in the souls of demons. The stage has collapsed and the audience is gone, but Charlie! The show must go on! Everyone: We can do it! We can build it! The best hotel we've ever seen! We'll double the rooms! We'll fill the hotel! Lucifer, Vaggie: It's up to you whether to start. Lucifer, Vaggie, Angel Dust: You know that, right? Everyone: Let's make your dream a reality! Charlie: Yes, because you all are with me!

Niffty: To build a hotel, we'll need bricks and wood! Lucifer: Be glad you're with me. Is this enough?! Angel Dust: Starting from the foundation! Lucifer: Behold my restorative creation! Guest, Niffty, Angel Dust: I can't believe work could be this easy! Charlie: No time for tears, there's so much to do! We have to do the best we can. Husk, Guest: New lights across the billboard, just one little bit of magic and it's done!

Vees Hotel Vox: The battle is over, and the cattle have lost their master. Vox, Valentino: The Overlords are looking quite precarious. At this rate, we could be running the show by tomorrow! Valentino: The rest of Hell is pissing themselves, Vox: And Alastor has disappeared! Vox, Valentino: He ran away with his tail between his legs! When there's a vacuum, it must be filled. It's the perfect opportunity for you and me. The future of Hell is now in our hands.

Alastor is... Alastor: This place is so full of the stench of death, even the air is creepy. Good thing I got out; I almost died by a hair's breadth. "The great Alastor, the altruist died for his friends"? Sorry to disappoint. I don't die like that! I crave freedom. There must be a loophole in this contract that binds me. Once I find a way to unfurl these wings, let's see who becomes the true puppet master!

After finishing the Hazbin Hotel Everyone: We can do it. (Charlie: We can do it.) It will get better. (Charlie: It will get better.) Even if redemption doesn't happen right away. (Charlie: Even if redemption doesn't happen right away.) Let's erase the sins of these unpredictable demons! Alastor: Let's start with a smile. Everyone: Yes! Charlie: We're going to make a change, just watch. We'll make it, all together! Everyone: And it's going to be a very happy day in Hell!
