Hazbin Hotel
Charlie Morningstar, the princess of Hell, opens a hotel called the "Happy Hotel", where she wants to teach demons of Hell how to be better people, in the hopes of getting them into Heaven. Due to overpopulation, Hell goes through an annual purge once a year, where angels descend from Heaven and kill demons. Charlie finds this upsetting, and wants to find a more peaceful solution to the overpopulation problem.
