(Hazbin Hotel Spoilers)
After the failure in the Hazbin Hotel finale, Lute became obsessed with getting revenge on the demons that killed her boss and destroyed her pride. Unable to get to any of the hotel residents though, due to Lucifer's presence. She decided to focus her efforts on the leader of the cannibal army, Rosie.
With her skill as an exorcist she was easily able to apprehend Rosie. All it took was some magic to turn the cannibal into a sweet treat ready to eat. Her ass seemed to take the most of the magic, fitting right into the cone Lute created. Of course, what's ice cream without some white chocolate syrup, sprinkles, and a cherry on top?
