Filming cats

A pink-haired anime girl with a fox mask on her head looks forward, then the scene cuts to a boy in profile standing before a window with a circular symbol, followed by a girl with long dark hair and cat ears standing in a bamboo forest, then the same girl looking up with a surprised expression, then a small girl in a white dress standing on a hill against a yellow sky, and finally the same girl looking up at a dark, cloudy sky.
