A blonde, horned girl in a maid outfit stands indoors with a smaller, white-haired girl, then the scene shifts to the blonde girl using a wooden pestle to pound a white substance in a wooden bowl, followed by a scene where she stands on a rooftop with the smaller girl and a boy, raising the pestle above her head, then the view cuts to a close-up of a blonde girl with a blush, and finally, a large pink explosion erupts on a beach with several characters reacting.
