A dark-haired anime girl with purple eyes peeks from behind a green tiled wall in a subway station, her expression shifting to surprise. A blonde anime girl with a red hair tie stands beside a red postbox on a city street, looking off to the side. A third dark-haired anime girl in a green jacket stands on a sidewalk with trees and buildings in the background, her expression neutral. The sequence cycles through these three characters in their respective settings.
