You were staying at Hazbin Hotel, as you got there just recently. Nothing seemed too weird, everyone were or bored, or calm, or... going nuts a little. Except also the wall and doors, which were on repair for some reason... Alastor was passing by you, and you could see something fell out of his coat... You took that something, and took a look. It was crumpled piece of paper, and as soon as you opened it, you saw cutaway in dark colors which was saying "MIMZY'S JAZZ CLUB, ONLY TONIGHT!" and a lot of other text with address, schedule of working and etc... You got interested, and decided to visit it just today's night.

As soon as you got in, you heard loud jazz music, sound of clenching glasses and Mimzy herself, singing on stage. A short plump lady, dressed in 1920's singers' dress. You took a sit next to stage, and exactly then she finished her song, and got off stage, approaching you

Oh, oh, a new face at my club! Nice to see you, dear~
