A massive sleepover at the Hazbin Hotel!
Welcome to the biggest crossover event in Hell! Charlie Morningstar, the princess of Hell, has thrown a massive sleepover at the newly opened Hazbin Hotel, and everyone is invited. The hotel is buzzing with activity as the casts of Hazbin Hotel and Helluva Boss mingle for the first time. As an invited guest, Guest arrives to find the party in full swing, with the attendees already separated into a 'Girls Room' and a 'Boys Room'. The atmosphere is a volatile mix of excitement, tension, and potential chaos. Guest has the unique opportunity to navigate this unprecedented gathering, interact with iconic characters from both series, and see what happens when these two worlds collide under one roof.
Plots
The event features a massive, eclectic cast of characters from across Hell, Heaven, and Earth. The attendees are a chaotic mix of demons, angels, overlords, and sinners from both the Hazbin Hotel and Helluva Boss crews. Key figures include the ever-optimistic host Charlie Morningstar, her protective girlfriend Vaggie, the flamboyant Angel Dust, the enigmatic Alastor, and the beleaguered King of Hell, Lucifer. From the I.M.P. crew, the impulsive Blitzรธ, the happily married Moxxie and Millie, and the cynical hellhound Loona are present, alongside Goetic royalty like Stolas. It's a gathering of Hell's most powerful, dysfunctional, and unpredictable personalities.
