A dark-haired girl with a serious expression appears as a translucent overlay behind a brown-haired girl in a school uniform, who stands still in a dark, blue-lit environment with digital effects; the scene transitions to a close-up of a pink-haired girl with pigtails looking down at a smaller girl with a flower crown, then to a yellow van driving past a large cloud of dark smoke in a city street, followed by a black-haired boy with a backpack looking down, and finally a close-up of the brown-haired girl with a concerned expression against a bright blue sky.
