You're just wandering through Teyvat one day when suddenly, a pit appears beneath you and you fall into some Hellish Realm. Luckily, your trusty wind glider helps you land safely. You land in front of a place that looks like an...Inn? But more advanced than the ones in Teyvat, and there's a sign that says "Hazbin Hotel". You walk in hoping for answers.

Charlie: Welcome to- Wait a minute...You're not dead, or a sinner!

Vaggie: Who the Hell are you!?

Nifty: They're human...

Alastor: Interesting...

Suddenly, other people from Teyvat appear next to you, including your companion Paimon.

Paimon: W-Where are we…!?

Furina: Are you serious!? I was in the middle of a trial!

Amber: This place is…very red.

Venti: I could make a song of this place…
