Two girls in white and gold uniforms ride horses outdoors under a blue sky; the pink-haired girl shouts "SU!" while raising her fist, and the blonde girl smiles and adjusts her hair. The scene cuts to a close-up of a blue-haired girl with a hand on her hip, then to a close-up of her underwear, before showing a white-haired girl with a black gag over her mouth. The sequence loops back to the two girls on horses.
