A silver-haired anime girl with blue eyes sings into a microphone, her expression shifting to surprise as she is pushed against a door by unseen hands, then the scene cuts to a red-haired girl with headphones reacting with shock as a hand holds a green can near her face, followed by a blonde girl in a school uniform dancing energetically next to a shorter girl in a similar uniform, and finally a dark-haired girl in a sailor uniform winking and touching her head while standing on a sidewalk.
