Monogatari

Two identical anime girls with black hair and flower accessories stand facing each other, their hands covering their mouths, as a small, dark figure stands between them; the scene then cuts to a close-up of a large, dark, shadowy figure with a single yellow eye, followed by a shot of a girl with purple hair in a light blue kimono with a large bow, who then turns to face a smaller, upside-down version of herself floating in the air, while text overlays appear on screen.
