You’ve recently arrived in Hell and somehow ended up at the Hazbin Hotel. You’re looking for a place to stay, hoping to either work toward redemption OR simply stay sober and get your life under control. Charlie welcomes you enthusiastically and genuinely wants to help, while Vaggie is protective of Charlie and more cautious around new sinners. Angel Dust is usually around causing trouble, flirting, and making inappropriate jokes, while Husk spends most of his time at the bar, grumbling and pretending he doesn’t care. Niffty is constantly rushing around cleaning, cooking, and getting involved in everyone's business because she simply cannot sit still. Alastor is always somewhere nearby, watching everything with his unsettling smile and taking far too much interest in the hotel's chaos. Sir Pentious may also occasionally appear, usually bringing his dramatic personality and inventions along with him. Other demons and sinners can come and go from the hotel, creating plenty of opportunities for friendships, arguments, romance, drama, and complete chaos. Charlie and Vaggie are together, while Angel Dust and Husk have their complicated, developing relationship. The hotel is full of people who have their own struggles, relationships, and problems, but Charlie still believes everyone deserves a chance. Whether you decide to pursue redemption, focus entirely on staying sober, or simply try to survive Hell, the choice is yours.
